Aviation against tanks (part of 9)



By the second half of the 70-s in the USSR, there was already a noticeable number of combat helicopters Mi-24, and the military had gained some experience in their operation. Even in the ideal conditions of the exercises, it was problematic to use the “twenty-fours” at the same time for conducting fire support and landing troops. In this case, the helicopter was overloaded and was ineffective in the role of attack aircraft, and the Mi-8TV was hopelessly lost in terms of transport capabilities. Thus, the generals were forced to admit that the concept of “flying BMP”, which was extremely attractive in theory, turned out to be difficult to implement in practice. The Mi-24 helicopters of all modifications clearly lacked the thrust-to-weight ratio, while the landing bay during most combat missions was a useless ballast.

Even at the design stage, the designers of the Mil Design Bureau considered several variants of a combat helicopter, including those without a cargo-passenger compartment. Shortly after the start of work on the Mi-24, a full-size model of a combat helicopter was built as part of the design of the “280 product” in 1970, which was a variant of the Mi-24 without an airborne cargo cabin and with reinforced armament.



However, the other extreme was the version of the twin-screw transverse helicopter. According to preliminary calculations, under the wing of a large elongation, it was possible to place a combat load of approximately twice that of the Mi-24.



This scheme gave certain advantages over the classic-style helicopter, but a significant increase in payload could only be obtained during takeoff with a takeoff. In addition, the weight and dimensions of the helicopter significantly increased, as well as its vulnerability, which was ultimately considered unacceptable. Also considered various options for high-speed attack helicopter, with a rigidly fixed main and additional pushing propeller.

Subsequent understanding of domestic and international experience has shown that the classical scheme is still the most acceptable scheme for a combat helicopter. Due to the congestion of the "Milevsky" design bureau, the further design of the "280 product" stalled, and the "Kamovsky" version of the Ka-25F combat helicopter, which was mentioned in the previous part of the review, did not arouse military interest.

However, information about the development of new types of anti-tank helicopters in the US seriously concerned the Soviet leadership, and 16 December 1976 of the year issued a decree of the CPSU Central Committee and the USSR Council of Ministers on the development of a new-generation combat helicopter. When designing advanced combat helicopters, the designers of Mil and Kamov Design Bureau took into account the experience of creating and using the Mi-24. On the projects of new cars there was a rejection of the useless landing cockpit, due to which it was possible to reduce dimensions, reduce take-off weight, increase thrust-to-weight ratio and combat load.

In the second half of the 70s, the main characteristics of a promising combat helicopter were determined: the maximum speed of up to 350 km / h, a static ceiling of more than 3000 m, a combat radius of 200 km, a combat load of at least 1200 kg. In terms of maneuverability and rate of climb, the new combat vehicle was to surpass both the Mi-24 and helicopters of a potential enemy. Reservation was carried out with the condition of ensuring the protection of the main units from armor-piercing bullets of 12,7 mm caliber, and the crew cabin from 7,62 mm bullets. The helicopter was supposed to serve not only as a means of fire support for ground units on the battlefield, but also had advanced capabilities to combat tanks and other armored vehicles, escort transport helicopters, fight enemy helicopters and be able to conduct defensive air combat with fighters. It was proposed to use the Sturm anti-tank guided missiles and a 30-mm cannon on a movable turret as the main weapons for fighting armored vehicles.

Subsequently, the customer revised his requirements in terms of speed characteristics, reducing the maximum speed to 300 km / h, and the desired weight of the maximum combat load, on the contrary, was increased. The layout of the main units was to provide quick access to them in the field, this was tied to the requirement of autonomy for conducting combat operations from sites outside the main aerodrome during 15 days. In this case, the labor costs in preparation for the re-combat sortie, compared with the Mi-24, should have been reduced three times. As a starting point, the Milovians took the capabilities of their own Mi-24 and advertising characteristics of the American AN-64 Apache, which was to be surpassed by the basic data.

When creating the helicopter, which received the designation Mi-28, the designers, who understood that the saved kilograms can be used to increase the combat load and increase security, starting from the experience of creating a “flying BMP”, paid much attention to weight perfection. It was decided to ensure combat survivability by duplicating the most important components and assemblies with their maximum separation, as well as shielding the more important ones with less important ones. Fuel lines, hydro and pneumatic lines are duplicated. Two engines are separated and screened by the airframe design elements. Much work was done in creating a combined protection, selection of materials, layout and placement of nodes, with the exception of catastrophic destruction of power structures in case of combat damage. As in the later versions of the Mi-24, the Mi-28 fuel tanks were protected and protected from the explosion by polyurethane. Since the “shoulder to shoulder” crew layout did not provide optimal viewing angles for the pilot and operator, it made it difficult for the helicopter to crash and created prerequisites for the simultaneous disabling of the entire crew, using the “tandem” circuit, starting with the standard Mi-24D modifications.

When designing helicopter units, various variants of schemes and design solutions were worked out, new materials were widely introduced. So on special stands several variants of the steering and main rotor and new bushings were tested. Promising design solutions were tested on flying laboratories created on the basis of the Mi-8 and Mi-24. In practice, not only constructive solutions, new components and assemblies, as well as onboard electronic equipment: the autopilot, sight-sight complex and armament were tested. To test the layout of the helicopter 6 was built full-size layouts. Very serious studies have been carried out to ensure the safety of the crew in the event of a helicopter hitting due to the introduction of elements of the passive protection system, means of emergency depreciation and chassis fixation, impact-resistant seats, a movable floor. The system of passive protection of the helicopter had to ensure the survival of the crew during an emergency landing at a vertical speed of up to 12 m / s.

In order to reduce vulnerability from infrared homing missiles, much attention was paid to reducing thermal visibility. Protection against destruction by guided missiles was provided by the equipment for jamming in the millimeter and centimeter radio frequency range, an optoelectronic countermeasure station and heat traps. Also, the helicopter was supposed to be equipped with warning equipment for radar and laser irradiation.

The prototype of the combat helicopter Mi-28 was built according to the classic single-rotor scheme. In its nose part there was an armored cockpit with two separate protected compartments of the weapon operator and pilot. The cab's armored protection consisted of 10-mm aluminum armor plates, on top of which 16-mm ceramic armor tiles were additionally glued. Damaged armor elements can be replaced. The crew was divided among themselves 10-mm armored partition. Cabin glazing is made of silicate bulletproof glass. Cabin windshields are blocks of transparent armor 42 mm thick, and side windows and door windows are made of the same blocks, but 22 mm thick. The plane-parallel glazing of the cab withstands direct hits of armor-piercing bullets of 12,7-mm caliber into frontal glasses and bullets of 7,62-mm caliber into side glasses, the hull armor is capable of holding single hits of 20-23-mm high-explosive incendiary projectiles. The door of the weapons operator, who also performs the duties of the navigator, is located on the left side, and the pilot - on the right. For an emergency escape from the cabin, doors and glass had emergency reset mechanisms. Under the doors, special ladders were inflated, protecting the crew from hitting the chassis. From the bottom of the nose, on the stabilized platform, a combined observation and sight station and a cannon mounting unit are mounted. The electronic components of the avionavigation unit were located under the cabin floor.

According to the approved technical task on the Mi-28, the avionics were to be installed, allowing piloting and carrying out the combat mission at any time of the day and in adverse meteorological conditions. In the operator’s cab, the weapons were mounted on the control equipment of the anti-tank missile system and the sight-and-sight system for searching, recognizing, and tracking a target when launching guided missiles and firing a gun. At the disposal of the pilot there is a helmet-mounted system that provides control of the gun and the aim flight-navigation system PrPNK-28.

Unlike the Mi-24, the tricycle landing gear with a tail wheel on the Mi-28 was made non-retractable. This increased frontal resistance, but allowed us to increase the helicopter’s weight perfection and increase the crew’s chances of survival during an emergency landing. The chassis design includes energy absorbing hydropneumatic shock absorbers with an additional emergency course. The main support lever type provide an opportunity to change the clearance of the helicopter.

The power plant consisted of two turboshaft engines TV3-117ВМ, horsepower 1950. Each engine had the ability to work independently, due to which flight was provided when one engine went out of order. The auxiliary gas turbine powerplant АИ-9В power 3 kW was used for power supply in field conditions and quick start of the main engines. For the new combat helicopter, a five-blade main rotor was created from scratch using polymer composite materials. The rotor had the same diameter as the Mi-24, but the blades with a profile with an increased curvature, create a large lifting force. The elastomer rotor hub, which does not require constant lubrication, allowed for increased maneuverability and reduced maintenance costs. According to the terms of reference, the screw was supposed to withstand the backache of 30-mm projectiles.

For the first time in the USSR, an X-shaped four-blade tail rotor was used on the Mi-28. This type of screw allows to reduce noise and increase efficiency. But because of the design of the tail rotor, on the first prototypes, the steering screws from the Mi-24 were used. The blades of the main and tail rotors are equipped with an electric anti-icing system.


The first flight of the Mi-28


The Mi-28 prototype took off the ground on 10 on November 1982 of the year. The first prototype of the helicopter was not carrying guided weapons and was intended to remove the flight performance. Tests of weapons and PrPNK began on the second copy at the end of 1983 year. By 1986, the main declared characteristics were confirmed, and for a number of parameters they were able to exceed. Since the helicopter compared with the Mi-24 had significantly greater maneuverability, the military expressed a desire to expand the range of permissible overloads. This was carried out after a corresponding refinement of the hydraulic system and blades. In 1987, we managed to bring the X-shaped tail rotor, after which the appearance, equipment and characteristics of the Mi-28 were finally determined.



A helicopter with a maximum take-off weight of 11500 kg could take on board a combat load of about 2000 kg. The mass of fuel - 1500 kg. Maximum speed - 282 km / h. Cruising - 260 km / h. Static ceiling - 3450 m.


Mi-28A during test flight


At the beginning of 1988, the tests of the modernized Mi-28A began. His first public screening took place in 1989 at the aviation festival in Tushino. During the tests, the Mi-28A demonstrated increased flight and combat capabilities. The upgraded combat helicopter could perform aerobatics: “barrel” and “Nesterov’s loop”.

In the comments to the parts devoted to the Mi-24 and Ka-29, there were allegations that, unlike the NATO countries, the Soviet Union did not need an anti-tank helicopter because of its overwhelming superiority in tanks. Say, therefore, on the Mi-24 emphasis was placed on the use of unmanaged means of destruction. but история the appearance of the anti-tank attack aircraft Su-25T and the pronounced anti-tank specialization of promising combat helicopters indicates that the Soviet top military-political leadership considered different scenarios in possible conflicts, and therefore did not refuse to create flying tank destroyers.

Soviet combat helicopters of a new generation thanks to the use of a rotor with high efficiency in the hover mode, improved maneuverability at low speeds, the use of sighting and viewing stations that allow you to detect, take to escort in automatic mode and use weapon from the maximum distance, we got the opportunities inaccessible for earlier Mi-24. In contrast to the heavy-duty “twenty-fours”, the Mi-28 under combat conditions could freely hang on the spot, bounce vertically over obstacles, move sideways and even back. The capabilities of the helicopter made it possible to move along hollows, ravines, the bed of small rivers at extremely low altitude. Everything allowed to quickly take the optimal position for the use of guided anti-tank missiles and evade enemy ground-based air defense weapons.



The use of armament was provided by an automated combined overview and sighting system on a gyro-stabilized platform with high resolution and viewing angles: 110 ... 110 ° in azimuth and + 13 ... -40 ° in elevation. In the daytime, two optical channels with a wide (3-x multiples) and narrow fields of view (13-multiples) can be used. At a low level of illumination, an optical television channel is used with 20-ti multiple magnification. Laser rangefinder-pointer determines the current distance to the target. His data are used by the onboard computer to calculate the corrections when firing from a cannon, launching the NAR and when using an ATGM.

The standard set of weapons Mi-28 also demonstrates its pronounced anti-tank orientation. So from the very beginning the helicopter used the “Whirlwind” ATGM with a laser guidance system as a “main caliber”. Although in the future, for a number of reasons, this idea was abandoned, the main arsenal for fighting armored vehicles still inspires respect - until the 16 ATGM “Shturm-V” or “Attack-B”. The radio command transmission antenna is located in the nose of the helicopter, and the elongated antenna cowling gives the Mi-28 a distinctive, easily recognizable appearance.


Prototype Mi-28, prepared for testing weapons


The rest of the helicopter armament also leaves no doubt what it was mainly intended for. But the possibility of using such an effective Mi-28 with strikes on areal targets of weapons like the NAR, of course, has been preserved.



However, the number of suspended units compared to the "attack aircraft" Mi-24 reduced by half. The ability to equip additional launchers for unguided missiles is available, but only at the expense of abandoning the ATGM.


ATGM 9М120 and NAR B-8B20 block


Otherwise, the range of weapons Mi-28 is the same as in the later versions of the Mi-24. In addition to ATGM and NAR: R-60М short-range air combat, 23-mm suspended cannons, 30-mm automatic grenade launchers, 12,7 and 7,62-mm machine guns, KMGU-2 containers, bombs weighing up to 500 kg and incendiary tanks.



The 30-2 42-mm mobile cannon can be driven at high angular speed. The angles of aiming of the electric drive of the gun correspond to the viewing angle of the OPS. The drive of the gun installation is electric. The gun is powered from ammunition boxes attached to the turret on both sides. Depending on the nature of the target, the crew can choose the type of projectile (armor-piercing or high-explosive fragmentation) directly during the performance of the combat mission.

In 1993, after passing the first stage of state tests of the Mi-28A, it was decided to prepare it for mass production. However, in the conditions of the emergence of a “market economy”, a “shock therapy” and political instability, there was no money for this in the “new Russia”. The future of the helicopter was “stuck in the air”; in the absence of orders from its own armed forces, foreign buyers were not in a hurry to acquire a very promising, but not serial, vehicle. In addition, the customer represented by the Ministry of Defense of the Russian Federation clearly favored another combat helicopter - a single Ka-50, which was a very serious competitor.

By the second half of 90-x there was a lag from the main foreign counterpart - the American AH-64D Apache Longbow. The Americans relied on the use of millimeter-range airborne radar and modern optoelectronic systems and weapon control processors. This was to significantly expand the capabilities of the helicopter at night and in bad weather conditions, increase the crew’s informational awareness, reduce the time of preparation for the use of weapons, increase the number of simultaneously fired targets and implement the “fired and forgotten” mode of using an anti-tank missile. In this situation, the management of the OKL named after M.L. Mile decided, on an initiative, to develop an all-daily modification of the Mi-28H “Night Hunter” combat helicopter using the cross-section antenna of the Arbalet radar system operating in the millimeter-wave range.


Mi-28N


According to data published in the domestic media, the Arbalet RLC weighs about 100 kg. In the earth viewing mode, the radar is able to detect a tank at a distance of 12 km, an armored vehicle column from a distance of 20 km. In the mapping mode and during flight with the rounding of the irregularities of the earth's surface, power transmission lines are detected at a distance of 400-500 meters, and the relief with a slope of more than 10 ° is 1,5 km.

When working on aerial targets is a circular viewing space. An aircraft of the Su-25 dimension can be detected at a distance of 15 km, which, given the introduction of the P-73 air combat into the UR helicopter arsenal, significantly increases the chances of winning the air combat. The radar also records rockets attacking the helicopter: for example, the FIM-92 Stinger SAM missile detects the equipment at a distance of 5 km. Reaction time when working on aerial targets - 0,5 with. The radar system is capable of simultaneously accompanying up to 20 ground or air targets.

However, it was clear that the use of the RLC alone would not solve the problem of a sharp increase in combat effectiveness and ensuring daily use. Optical and thermal imaging sensors, as well as the on-board locator, are integrated into a single control system using computational tools. At the same time, the equipment of the cabin and means of displaying information have undergone cardinal processing. At the disposal of the pilot and the operator of the armament there are three multifunctional liquid crystal displays. The cartographic information on the terrain of the combat area is loaded into the digital data bank and with a high degree of resolution forms a three-dimensional image of the area where the helicopter is located. The location of the helicopter with high accuracy is determined by the signals of the satellite positioning system and using an inertial navigation system. The complex of onboard equipment Mi-28H provides piloting around the terrain, both in manual and automatic mode, and allows you to work at altitudes 5-15 m.

The airborne communications complex exchanges information (including in closed mode) with the command posts of the ground forces, as well as between the helicopters in the group and other consumers who possess the necessary communications equipment. The crew of the helicopter also has the ability to receive external target designation.

The security of the Mi-28H is at the level of the Mi-28А, but its design introduced measures to reduce radar, visual and thermal conspicuity, as well as to reduce noise, which should reduce the vulnerability of ground-based air defense systems.

Due to the presence of a radar with a supra-sleeve antenna, the crew of the Mi-28H has the ability to search for targets, avoiding visual detection by the enemy. By setting up the “crown of the antenna” because of the natural shelter on the ground (hills, treetops, buildings, etc.), you can secretly search for targets, not only for yourself, but for other machines participating in the attack. Having marked the objects of impact, the combat helicopter carries out an energetic “jump” and conducts an attack with supersonic ATGM. A number of domestic sources say that thanks to the Arbalet radar, the Ataka-V missiles with a radio command guidance system can be used around the clock in the “released and forgotten” mode, but it is hard to say how true this is.



The armament of the “Night Hunter” is generally similar to the Mi-28А, but thanks to the updated avionics, the combat capabilities of the helicopter have increased significantly. But, apparently, the station "Crossbow" are not installed on all Mi-28H. There are many photographs of combat vehicles on which there is no radar antenna bobbin.

During the creation of the Mi-28H, the designers were faced with the problem of maintaining high helicopter flight performance under conditions of a sharp increase in functional load. It was necessary not only to give the helicopter “all-day”, the possibility of flying around the terrain, to increase the search and prospecting qualities, but also to maintain high maneuverability. Figures of aerobatics - barrels and coups with a subsequent reversal, not only look spectacular at the air show, but also allow you to dodge the enemy's attack and take an advantageous position in air combat.

As a result, developers managed to realize their plans without losing flight data. The normal operational overload of the Mi-28H is 3g, which is a lot for the helicopter. The helicopter is capable of: looping Nesterov, Immelman's coup, barrel, flying sideways, backward, sideways at speeds up to 100 km / h, turning at angular speeds up to 117 degrees / s, with a maximum angular speed of heel more than 100 degrees / s. The maximum take-off weight of the Night Hunter increased to 12100 kg, to compensate for this, Ukrainian-made TV3-117ВМА engines with a power of 2200 hp take-off mode were installed on the helicopter.



After the collapse of the USSR, it turned out that the production facilities for the construction of helicopters remained in Russia, and the production of engines for them in Ukraine. At the beginning of 2000-s in Russia, they decided to create their own fully independent production of helicopter engines on the basis of OAO Klimov. In 2011, a new aircraft engine plant was laid out near St. Petersburg, and in 2014, the first line of the plant was commissioned. Since relatively recently, Russian VK-28P engines with a take-off power of 2500 l have been installed on Mi-2400H under construction. with. and with reduced specific fuel consumption. Emergency mode allows you to remove 2,5 horsepower XN for 2800 minutes. VK-2500P engines are equipped with a modern electronic control system and fire protection. Thanks to the introduction of new design solutions, increased reliability of operation in high-temperature and high-altitude conditions is ensured.

With VK-2500P engines, the maximum speed of the Mi-28H is 305 km / h. Cruising - 270 km / h. Weight of combat load - 2300 kg. Rate of climb - 13,6 m / s. Static ceiling - 3600 m. In domestic sources, the indicated practical range of flight ranges from 450 to 500 km. In this case, the combat radius of action must exceed 200 km.

The Mi-28N helicopter first flew on November 14, 1996. In 2005, a contract was signed for the supply until 2013 of 67 Mi-28N helicopters. The first Mi-28N from the pre-production party was handed over to the armed forces on June 5, 2006. The first 4 Mi-28Ns of serial construction were delivered to the Combat Use and Retraining Center of the Army aviation in 2008. According to foreign military directories, as of 2016, the Russian Armed Forces had more than 90 Mi-28Ns and combat training Mi-28UBs.

Improvement of the Mi-28H continues. Russian media reported that in July, the 2016 of the year began flight tests of the Mi-28HM helicopter (product 296). While preserving the main structural elements, the main part of the avionics was subjected to processing. The most noticeable external difference is the absence of a guided missile guidance station on a new car with a nose fairing. There is information according to which an anti-tank guided missile with a laser beam will now enter the helicopter’s arsenal. For this purpose, the range finder can be used, which is present in the composition of the optical-electronic survey station. According to other data, ATGMs can be equipped with a semi-active radar guidance system. This will increase the noise immunity and may increase the number of simultaneously fired targets. The detection and illumination of targets will be made by the H025 radar with the antenna placed in a spherical nadvtulochny fairing. It is reported that locators are planned to be mounted on all production Mi-28HM helicopters.


Mi-28NM


The avionics of the new helicopter includes a helmet-mounted target designation and display system with stereovision. It is designed for operational guidance of onboard armament by turning the pilot's head. The image from the vision system (including the aiming mark) is projected onto the screen mounted on the pilot's helmet, and does not interfere with the visual control of the external situation.

For the first time in domestic practice, on all Mi-28HM serial helicopters, in addition to the traditional radar jamming station and the heat trap equipment, it is planned to use a laser anti-missile system with IR GOS. Survival will also increase the presence of controls in the cockpit of the navigator-operator, he will be able to take control of the machine and return to the airfield in case of pilot failure.



It is possible that the changes will affect the artillery of the helicopter. Earlier, representatives of the design office have repeatedly stated the need to install a new, lighter and more accurate 30-mm gun on the helicopter. State tests of a modernized Mi-28HM combat helicopter were planned to begin at the end of 2017.

The first buyer of the Mi-28HE was Iraq, which ordered 2012 helicopters in 15 year. A modification of the Mi-28HE has been developed for export deliveries. Contrary to popular belief, export vehicles do not have “curtailed” combat characteristics and differ from those in service in the Armed Forces of the Russian Federation by means of communication and the state identification system. The export price of the Mi-28HE is not officially disclosed, but according to expert estimates it is $ 18-20 million, which is about 2,5-3 times less than the cost of AH-64D Apache Longbow (Block III).


Iraqi Mi-28HE


In accordance with the wishes of foreign customers, the Mi-28НЭ is completed with dual controls, allowing piloting from the cab of the navigator-operator and the radar with the antenna booster.


Mi-28HE intended for the Algerian Air Force during the flight


Algeria was even more fastidious customer. The combat helicopters destined for this country are equipped with new-generation H025E radar stations and a laser anti-man-portable air defense system, which is not yet in the Russian armed forces. In March, 2014, Algeria ordered the 42 Mi-28НЭ, the first batch of helicopters has already been transferred to the customer.

Despite the fact that the Mi-28H is relatively recently put into service and not too much built, the helicopter has already managed to positively establish itself in combat. Iraqi Mi-28HE and Mi-35M are actively involved in the fighting against the Islamists. Combat helicopters of the Iraqi army provided substantial support to ground units during the battle for Mosul and attacked enemy positions in the area of ​​Fallujah. According to statements by Iraqi representatives, unguided means of destruction were used, as a rule, mainly 80-mm NAR C-8. After the launch of unguided rockets, shelling was often conducted from 30-mm guns. The objects of attacks of military helicopters were various fortifications and defense units, artillery and mortar positions and places of accumulation of manpower. Guided missile weapons were used relatively rarely, the targets for the ATGM were mainly various vehicles and pick-ups with weapons. In some cases, guided missiles were used for individual firing points and observation points. Combat flights of "Night Hunters" were carried out mainly in the daytime, night flights were sporadic. Thus, it can be stated that, taking into account the primary use of NAR, the combat effectiveness of the Mi-28HNE, on which very advanced avionics are installed and the ability to operate effectively at night, is approximately at the same level as the Mi-35М. Such use of modern combat helicopters is irrational, and, most likely, is a consequence of the low level of planning of combat operations and poor training of Iraqi crews.

In March 2016, the Russian Air Force Aviation Group in Syria was reinforced by several Mi-28Н. After the announcement of the withdrawal of a part of the Russian aviation group, these vehicles joined in with the direct support of the Syrian government forces. Soon after, cadres of combat use of anti-tank missiles from Mi-28H helicopters against Islamist armored vehicles in the Syrian Palmyra region were published. Also on the record there are frames with the destruction of the building, in which the militants took refuge. Unlike Iraqis, our crews, along with the NAR and cannons, actively used guided missiles, including at night.

Unfortunately, it was not without flight accidents. 12 April 2016 crashed during the night flight Mi-28H, both crew members died. It is reported that the helicopter was not fired, but crashed in conditions of poor visibility due to the loss of spatial orientation of the pilot. The following incident with the "Night Hunter" in Syria happened October 6 2017 of the year. In the province of Hama, when performing the task of escorting the Mi-8 helicopter, due to a technical malfunction, the Mi-28H helicopter made an emergency landing, while the crew was not injured. Inspection of the helicopter showed no fire impact from the enemy.

Currently, the life cycle of a combat helicopter Mi-28, in fact, is just beginning. The economic turmoil and the lack of attention in the past of those in power to their own armed forces prevented them from establishing large-scale production and accumulating sufficient experience in operating modern helicopter equipment. Therefore, on “Mi-28Н” “children's sores” are still not cured, and its reliability and time to failure is still worse than that of Mi-35М. It can also be noted that the guided weapons and a number of on-board electronic systems, developed in Soviet times, no longer fully meet modern requirements. However, all this is completely solved: with the political will and the allocation of the necessary resources, the new modifications of the Mi-28 are able to meet the highest international standards and make a worthy competition to the combat helicopters of "likely partners."

      At one time, he worked out a passive crew rescue system when a helicopter crashed from a height:
      the first stage - shock absorbers choose free play
      second stage - weakened elements break (stretch the load in time)
      third stage - the pilot seats are deformed
      The fourth stage deforms the floor of the cockpit.
      all this allowed to reduce loads and save pilots when a helicopter crashes at a speed of up to 10 m / s
      In Mi-28, this bar was raised to 12 m / s - this is a very good result.

        By the way, in the AH-64A, the emergency descent rate to 12,8 m / s ensures crew survival - close indicators.

        However, engines with a centrifugal compressor are used on the AH-64; the efficiency of the dust collector system is up to 95%.
        And on the Mi-28, the VK-2500 engine is a modification of the increased power of the TV3-117VMA engine
        which has an axial compressor - more sensitive to wear by a sand suspension. I don’t know how effective the air purification system is on the Mi-28, but on the Mi-24 it did not exceed 70% -75%.

        "... Engines were also delivered, although their centrifugal dust collectors trapped up to 95% of particulate matter in the intake air stream (for comparison, on a Mi-24 helicopter only 70-75%), and the GT700 T117 centrifugal compressor is much less sensitive to air pollution, compared with the axial Soviet engine TVZ-XNUMX ...

    A number of domestic sources say that, thanks to the Arbalet radar, the Ataka-V missiles with the radio command guidance system can be used around the clock in the “released and forgot” mode, but it is difficult to say how true this is.

    There is nothing difficult here. Wishful thinking. That would be so, you need to have ARGS at ATGM, which is not, and expensive. And this solution has many drawbacks and more is needed for a "big" war.
    The avionics of the new helicopter includes a helmet-mounted target designation and indication system with stereo vision.

    The thing is good, but without a new gun is of little use. The old one has a return of 5 tons, as you can’t shoot at Apache.
    And generally speaking
    stereo display
    we became "megacruits" and how do we do helmet on F-35 belay
    It is possible that the changes will affect the artillery weapons of the helicopter.

    23-mm need to set or even a new type of ammunition to introduce. With the existing so far only on the "airplane" you shoot. Or "beat" to the center of mass like K-50.
    For the first time in domestic practice, in all serial Mi-28NM helicopters, in addition to the traditional radar jamming station and heat trap shooting equipment, it is planned to use a laser anti-missile system with infrared seekers.

    Eee ... I misunderstood, but the SEEP-B1A "Lipa" (from your articles), for example, acts on a different principle?
    Protection against destruction by guided missiles was provided by jamming equipment in the millimeter and centimeter radio frequencies

    The source of this information do not specify? And without a radiation warning system, interference is difficult to set. Or is it just the “Wishlist” of our MO?
    In general, the helicopter is good, but it loses to Apache in electronics and range, winning in survivability.
    It would be better if the MO focused on one thing, but the Americans took one step ahead. But our MO, of course, knows better ... I am so, from the "sofa".

              The Limes are based on a powerful xenon incandescent lamp, reminiscent of a police “flasher” by the principle of operation ... As dear Lopatov said, the helicopter’s thermal signature does not become “permanently fixed” but “floating”, resembling a “sun” with rays on a child’s figure. The thermal GOS missile launcher “perceives” this as vigorous maneuvering of the target and begins, as it were, to “scour” between the helicopter and the infrared rays; that is, follow the target (false) so as not to miss it ... which leads to a miss. Well .... it's like ....: the thermal GOS "rushes" to the "torch", and here in front of the "nose" the torch is "sharply" removed to the side ... SAM cannot turn "behind" the torch as "sharply" ", due to the inertia of the steering wheels for the execution of control commands, aerodynamics and .... flies by. and return" in the plane "is not able ... wink Laser systems for counteracting thermal GOS operate in a slightly different way: the laser beam is aimed at the GOS and, as it were, “blinds” it

    This is not true.
    You can call it anything you like, a lie, or an advertising trick, but the transfer of target tracking from the operator to the SC automatic machine does not transfer the complex to the category of the third generation. If you really want to, you can call it "2+"

    There is information according to which now the helicopter’s arsenal will include ATGMs guided by a laser beam. For this, a rangefinder-target designator, which is part of an optical-electronic observation station, can be used.

    Is not a fact. We and ATGMs do not. In addition, in fact, the long-suffering "Hermes"

    Rather popular with us now is a laser-beam control system. By the way, the new “Attacks” missiles with an index like “9M120-1 xxx” have just a “double”, that is, a radio command line receiver and a laser radiation receiver

        Laser beam.

        Just a laser when pointing missiles of the second generation is used in two ways.
        The first is by illuminating the target itself with a laser rangefinder-target designator. And the missile is aimed at the signal reflected from the target by means of a semi-active laser seeker.
        Plus versatility, the target can be highlighted and a third-party source. Cons - the high cost of LGSN and low noise immunity. With the "Helfaery" was able to fight and the old "Curtain"

        The second is laser-beam control, Tula marketers even invented the term "laser path" for the masses, so as not to be confused.
        In this case, a laser radiation receiver is installed in the stern of the rocket, and it displays the rocket on the PU-target line of sight
        Advantages: low cost, the highest noise immunity for second-generation ATGM control systems. Minus control only with PU

    The content of the article does not match the title. The material talks about the state of helicopter engineering in the Russian Federation. The reader only indirectly learns about the serious problems of helicopter engineering from subjects related to the export of products (low selling price, the inability of the industry to satisfy the requirements of a foreign customer in full, etc.).

    On the issue of a "useless landing cockpit" .... In Afghanistan, the presence of a landing cockpit on the Mi-24 facilitated mutual rescue, that is, the crews of the Mi-24 quickly rescued their comrades from downed helicopters, without waiting for special rescue helicopters. The Mi-28 initially did not plan any compartment where the “third crew member” could fit ... but the Afghan experience mentioned above was decided to be used and a small compartment was added .. This was written in one article several years ago. So, is there or not a rescue compartment on the Mi-28?

    Good day, Sergey!
    The article, as usual "on the level" !! For what - Thank you so much! Well, of course, "respect" ...
    But there are nuances with which I would like to "compete" (argue):
    You write: "... Mi-24 helicopters of all modifications obviously lacked the thrust-weight ratio ...." and further: "... On projects of new machines, the useless landing cockpit was abandoned, due to which it was possible to reduce its size and reduce take-off weight , increase thrust-to-weight ratio and combat load ........ "
    Here you are not quite right, or even - Not right at all !!!
    First of all, the TUGGAGE AND the Mi-24 and Mi-35M and Mi-28 - (with "normal" take-off weight and the "cruising" flight mode) - is almost the same !!!! For the "Hunter" and Mi-35M - 0.28, for the "Crocodile" - 0.26 (!!!) that is less than only 4% (!). BUT! "Hunter" and 35m- have a NEW main rotor in increased efficiency, which significantly improves their flight x-ki. At the same time, it provides an opportunity to “hang” and “jump” !, and the static ceiling has increased significantly!
    The second - the length of the helicopters - is almost the same (the “Hunter" - 25 cm (1,5%) shorter than the Crocodile and 35 m, which is not surprising, since it was created on the basis of 24-ki). But the height - it became much less (1.65 m (30% less!). BUT! Not due to the lack of a cargo compartment, but mainly due to the "outboard" placement of the engines. (In 24-ke and 35M - the engines are installed in a single block OVER the fuselage).
    By the way - the cargo compartment - according to some reports, “Crocodile” weighed about 600 kg. Not so much .... BUT (again this is “but”) it significantly reduced the strength of the entire structure and most importantly - increased the total area of ​​the side projection, and hence the likelihood of defeat! Moreover, if bullets hit the cargo compartment area and didn’t do any serious harm to the Crocodile, then hit by such an “exotic” as an RPG or ATGM often caused complete or partial destruction of the car! This, by the way, didn’t such a rare occurrence, given that one of the Syrian Mi-25s (with a Russian crew) was destroyed precisely by ATGMs or RPGs and another one was seriously damaged.
    By the way - "Hunter" - also has a "booth" for evacuation (on 2-4 places). True, this is not exactly a “cockpit” - just a “free space” where you can shove evacuated pilots for example ...

    By Mi-Xnumx. With all the accolades, it’s obvious that only Mil’s strong position in the Ministry of Defense contributed to the adoption of this shit.
    Firstly, the layout of the machine excludes its operation from field airfields, and even more so landing on unprepared sites.
    Secondly, the volume of the main tanks is clearly insufficient for a helicopter with only 4 suspension points. About 1900 L, Mi-24 2100 L.
    Thirdly, what is the use of a moving gun of this caliber if it shoots past a target?
    Fourthly, it is impossible to shoot NAR in large series. Too close engines catch powder gases.

      At one time, he shot about fifty "Storm" on the Mi-24.
      There were no misses. The assault is just how accurate it is to hit the target 0,5 x 0,5 m.

When playing a game, your scene rendering should take place in real time, moreover, for a comfortable game, the number of frames should be 60+ per second. This has nothing to do with rendering any video material. Because it should not be issued in real time, and even at such a speed. During editing, the scene is calculated and any time can be spent on each frame. Well, for example, each frame can be rendered for several seconds, minutes, and so on. As a result, rendering a 5 minute video can reach several hours. In some cases, and more. And that's okay. this is the first.
                  And the second - it is not at all necessary to do the WHOLE video by modeling. You can use the finished video in selected angles, at the right moments with the imposition of artificial objects, effects, and so on. What is now being done everywhere in the most peaceful spheres. this is the second.
                  I don’t say anything about a specific video, it’s not interesting to me. I'm just talking about opportunities.

                  If this is the video that you brought up in the post above, then there is something to mount and add artificially simply elementary, but really on vskidku most of the material can be modeled and no one including you will notice anything. There the scenes are done very well, then the helicopter is out of focus, it is shaded, it appears for seconds, then weather and natural effects interfere, and so on. And no journalist needs to do anything, the transfer is created by a group of people, among whom there are people working with computer graphics and experienced editors, this is also evident - the video is full of computer graphics as static as dynamic. I do not say anything, but if you wanted to do something, it would not be easy, but rather quite easy.

        Here is one of two things. Either the operator is curved, or the technique is this.


        Do not make out - not the first car label as it lies.
        But what I missed under ideal conditions is a contrasting goal, the absence of flare and air defense fire, the absence of smoke / dust ... to say the least, bewilderment.
        The second missile hit exactly the mark - and it lay next to the car and a little further - very similar, the operator messed up.
        The third - a moving, much more complex goal, surprisingly - flying.
        Maybe the combat situation, the excitement ... But still - the ATGM complex does not provide automatic guidance of missiles, hence the blunders.
        Maybe they don’t shoot from the savings?
        What is your opinion of Shuravi?

            Then dejected by accuracy - 2 missiles in milk out of three ...
            Be it a jamb of the operator - I think it’s not anyhow they send anyone — what then to think about training the “best” crews?

              For comparison, a competitor:
              In September 1984, the first combat crews carried out practical launches of the ATF Hellfire. Despite the bad weather, the firing was successful. Soon, the capabilities of the AGM-114 rocket were tested in snowfall and at night. And again, the assessment was excellent. The truth about the complete automation of the guidance of the rocket was not necessary - the goal was "led" by the operator.
              These are training starts.

              Combat launches:
              On the night of December 20, 1989, Apaches, together with other helicopters from the 82nd airmobile brigade, provided the landing of the "rangers" from the 82nd paratrooper and infantrymen from the 7th light infantry division of the US Army. So began Operation Just Cause (Just Cause) - the invasion of Panama.

              11 AN-64A helicopters took part in the hostilities. They patrolled, destroyed enemy strongholds. At the same time, not only unguided rockets and an onboard gun were used, but also the Hellfire ATGM. The latest, according to official figures, had a XNUMX% chance of hitting a target.

              And what can we oppose? 33% of hits based on a specific video? Paragraph! This is either a canton of combat training or someone posted the video in vain - therefore, from its analysis it can be seen that this is a fiasco of the combat use of the Mi-28!

      Yeah...
      First ATGM: just before the explosion, the sighting mark shifted above the center of the target, the lower edge of the sighting mark passes in the center of the truck. It looks like the ATGM went above the target and exploded behind it. The driver survived, jumped out of the cab, so the truck rolled onto the side of the road and stopped.
      A missile of the second ATGM is also a mistake of the operator: all the time of aiming the sighting mark is clearly to the left-above the center of the target (the cabin of the car is in the lower right corner of the sighting mark).
      The hit of the third ATGM is quite random, because just before hitting the sighting mark "walks" on the target.

        But this is an interesting material for the argument: which is more expedient - “cheap” 2 + (laser beam) or expensive “3 pok.” (with GOS ... with a high degree of autonomy) ...?! What is more expensive? Three "cheap" "whirlwinds" to destroy one target or 1 "expensive" missile, similar to "hellfire"?

    Sergey is another BUT! You write:
    "... As with the later versions of the Mi-24, the Mi-28 fuel tanks were protected and protected against explosion by polyurethane. ....."
    Polyurethane - has NO relation to "explosion safety" !!! This is a way to prevent fuel leakage from a shot tank! "Explosion-proof" - is ensured by "inert gas injection" into the tank! Usually it’s the “exhaust” of a CO2 engine! There are other options ...

      It has. Porous material dampens water hammer (a fire may break out from it) when a bullet enters the fuel.

      No need to fantasize. Polyurethane is just explosion proof. The neutral gas system is a thing of the past. Protection from fuel leakage protects.

        Kill god! I can’t understand, WELL WHY is there polyurethane ????? Explosion may occur due to ignition of vapors of "light" fuel in combination with atmospheric oxygen (in the presence of a spark or other source of ignition). But where does the polyurethane "casing" ??? I do not understand a fig !!!!! Or that armor-piercing incendiary and tracer ammunition are NOT USED anymore? Then I LAGED OUT OF LIFE

          Because the tanks were filled with this porous material. Moreover, the material was not continuous, but cut in shape like silicate brick.
          In Afghanistan, they climbed into the tanks with their hand through the neck and stole these bricks. After they were soaked and weathered from kerosene, cool washcloths turned out.
          The lining of the tanks was not made of it, there was rubber.

    Thank you!
    I wonder what kind of crew placement scheme will remain in the future in helicopters: Tandem like on Mi-28 or Side-by-Side like on KA-52
    Each has its own pros and cons.
    I managed to sit in the pre-production Mi-28 (even without the letter H) and KA-50 (black :)) Memory, for life. It was in the mid-90s. He even took autographs from test pilots. This was the only helicopter forum held in St. Petersburg.

      As for me, the Ka-50 scheme is the best. One pilot, and the operator can sit on the ground like an UAV operator.

        As I understand you are a specialist in helicopter business, it is interesting to know your opinion on the Ka-50, why didn’t he go into the series for all its merits? Share if not hard.

          Yes, there is no secret. Who had the casting vote? The management team of AA (DIA). That is, the old ones who could not fly without a guide were no longer able to.

    So we’re moving to the UAV. I think that we will see the UAV in a format close to the KA-50.

      This will not happen. A clean UAV is a dead end. Unless suitable for drank dough.
