40 years to the legendary Mi-24 combat helicopter (part of 1) Creation

53
In 2013, exactly 40 celebrated the years since the launch of the Mi-24 multi-purpose attack helicopter at the Rostov Helicopter Plant (now Rostvertol OJSC). Multi-purpose military transport helicopter Mi-24 was the first domestic helicopter specifically designed for combat operations. Its design was so successful that the modifications of the Mi-24 are still in use today. Currently there are about 1500 helicopters of this type, which are in service with 60 countries of the world. A total of 40 years was built around 3500 Mi-24 helicopters.




History The creation of a domestic armed helicopter capable of supporting ground forces with its fire weapons dates back to the 1950s. The first attempt in this direction was to equip the ATGM 9M14M "Baby" first-born M.L. Mile of Mi-1 helicopter. It was followed by a transport and combat helicopter Mi-4AV. Almost 185 Mi-4AV, equipped with a heavy machine gun A-12,7, four ATGMs "Phalanx" and NAR S-5, were first used in the Military Transport aviation, and then - in the front, which supported the Ground Forces.

Abroad, the idea of ​​an armed helicopter was implemented in the UH-1H Iroquois helicopter, which was widely used in hostilities in Vietnam. He carried the soldiers and supported them with fire. But gradually, Western experts came to understand that the attack helicopter is only a platform for various weapons, and the landing of the landing force should be carried out by an amphibious transport vehicle, but also armed.

In our own country, the concept of a transport-combat helicopter won, supported by Defense Minister Marshal A.A. Grechko. The new rotorcraft actually had to become a flying combat vehicle of airmobile infantry. In 1967, at the pilot plant of OKB ML. Mile built two layouts and several variants of the bow of the machine, called the B-24. They reflected two main approaches to solving the problem: the first was a helicopter with a take-off mass of 7 and one TVZ-117 engine, the second with a mass of 10,5 and two TVZ-117. In the same year, the Ministry of Defense announced a competition, in which the Moscow and Ukhtomsky helicopter factories took part.

Mi-4AV helicopter


The Milev team presented the B-24 project — the future Mi-24. Kamovtsy offered Ka-25F - a modified ship helicopter. His armament included a mobile unit with an 23-mm gun GSH-23, six Phalang-M ATGM, or six UB-16 units with 57-mm NAR C-5, or aerial bombs. In the cargo compartment housed up to eight paratroopers. On the take-off mass, this car was close to the first variant of the B-24, but significantly inferior to the second in maximum speed; combat load equivalence was achieved by the extreme use of the modernization potential of a serial vehicle. These circumstances, apparently, influenced the choice of a more promising B-24 with two TVZ-117.

Speaking of B-24, it is impossible to ignore the contribution to the creation of the OKB LMZ helicopter. V.Ya. Klimov. Under the leadership of the chief designer S.P. Izotov in 1965 began the development of the TVN-117 HPN XX engine. This team in 2200 - 1960's. created the first domestic helicopter gas turbine engine TV1965-2 with power 117 hp Now Leningraders offered a new generation engine of the third generation: one and a half times more powerful and shorter than the TV1500-2, which is much lighter and more economical.

The layout of the second version of the B-24 with two theaters


OKB M.L. Mile drew attention to TVZ-117 from the start of development and first proposed it as a power plant for the Mi-14. It is quite natural that the Millevtsy used the engine with such high technical characteristics on the B-24, where it “came to court”. Despite the large number of new design and technological solutions, the first prototype TVZ-117 LMZ manufactured in December 1966.

The model of the B-24 helicopter was armed with the GS-23 aircraft gun. On the side frames under the cargo door, a pair of anti-tank 9М17М "Phalanx-MV" was installed with the RCX. Beam holders for four bombs or NAR units were placed on a small wing without a transverse “V”.

Representatives of the Ministry of Defense, who were part of the mockup commission, suggested replacing subsonic anti-tank guided missiles with a manual targeting mode with supersonic rockets with a semi-automatic PKNS, and the GSH-23 cannon with a XNUM g. XMX high-caliber machine gun.

The full-scale development of the B-24 began in accordance with a resolution of the USSR Council of Ministers on 6 in May of 1968. On the same day, government decrees were adopted to create a TVZ-117 engine and a unified supersonic PT-RK 9-113 for an army helicopter and a self-propelled launcher. The general management of the creation of the B-24 was carried out by the general designer M.L. Miles, and after his death - the chief designer M.N. Tishchenko; technical management was assigned to the Deputy Chief Designer V.A. Kuznetsova, and the first lead designer was VM. Ol-shevits.

The first prototype of the B-24 in its original form


The first prototype B-24 after installing weapons


The profile of the main rotor blades for B-24 was selected at TsAGI, but by the time the first machine was built, this work was not completed. Then, at the suggestion of one of the OKB's leading designers, a new blade was manufactured at the Kazan Helicopter Plant: the nose with a cellular aggregate from the Mi-8 was attached to the nose blade with a spar from Mi-4 - the blades had the same NACA-230 profile. Compared to the Mi-8 blade, it turned out to be shorter by 2 and wider by 20. Such a decision was considered successful, and later a scientific substantiation was brought under it.

But over time, it turned out that the Kazan hybrid creates significantly less cravings than the Mi-8 screw. The static ceiling at B-24 in standard conditions was 0,8 - 1,3 km. This was clearly not enough in the mountains of Afghanistan, where the combat helicopter yielded Mi-8MT with similar engines for take-off and landing and traction characteristics.

In addition, the composite blade created a large pivot point. Especially significantly it increased with increasing barometric altitude and vertical overload. The power of the hydraulic boosters when performing a slide or a turn of the battle was often not enough to overcome the total effort from the hinge moments of all the blades. As a result, there was a temporary "jamming" of control in the longitudinal direction. It took the development of more powerful boosters and the gradual replacement of the originally developed power actuators by them.

A distinctive feature of the aerodynamic layout of the B-24 was the inclination of the main rotor shaft to the right of the vertical plane on 2,5 ° together with the power plant, caused by the desire to improve the accuracy of firing from a fixed weapons. This was due to the fact that the characteristic flight modes of the helicopter are hovering with a slight heel and flying with a slight slip caused by the need to balance the lateral component of the thrust of the tail rotor. Due to the inclination of the plane of rotation of the rotor, the roll and slip in all modes turned out to be minimal: roll - 0,5 - 1,5 °, slip - 1 °. For unloading the tail rotor when flying at high speed, the end beam had a relatively large area (2,8 м2) and an asymmetrical support profile. At maximum speed, the beam creates an 67% of the lateral force necessary to balance the rotor moment of the rotor.

When designing the B-24, special attention was paid to increasing combat survivability by reserving the main and backup hydraulic control systems, fire protection, installing a neutral gas system, as well as booking the crew cabin and the most important units and devices. Emergency chassis and power supplies were envisaged. The redundancy included dual control of the machine from the workplaces of the pilot and operator, and much more.

The requirements for B-24 were so high that the domestic industry could not implement them in full and on time. The cost center management, in an effort to speed up the process of creating a new machine, launched into production a prototype model B-24 (product 240) even before its layout was approved by the state commission.

Modified B-24 with an extended cabin, a wing with negative transverse V and a steering screw on the left side


Therefore, instead of a mock-up of the commission, in February 1969 was presented the first prototype of the helicopter. A distinctive feature of this first version of the machine was the crew cabin with flat glazing, under which the weapon operator and the pilot were placed one behind the other with a shift. Representatives of the Ministry of Defense revealed a lot of flaws, made a number of comments and suggestions, but some of the flaws then detected “fit” forever in the car. The test pilots of the Air Force Scientific Research Institute and the pilots of the Lipetsk 4 pulp and paper industry and PLC agreed that the B-24 crew cabin layout does not provide the required view of the airspace.

The first B-24 flew 19 in September of the same year G.V. Alferov. In the factory tests of the first two models of the B-24, besides Alferov, the pilots G.R. Karapetyan and M.A. Material, flight mechanics V. Tarabukhin and F. Novikov. The lead flight test engineer was B.V. Meanings.

For state tests, five prototypes of B-24 were built in Moscow and five more - in 1970 at the Progress plant in Arsenyev (Primorsky Krai), where they were preparing for mass production of the new helicopter. Preparations for the release of the series, which began before the completion of state tests, were quite in the tradition of the Soviet aircraft industry: after the completion of the main volume of tests, a preliminary conclusion was signed, which gave the plant the right to start mass production. Of the Arsenyev five, the first machine was intended for life tests, and the fifth was for testing the Shturm-V anti-tank missile system.



An obstacle to the launch of the series was the lag in the development of weapons and engine systems: TVZ-117 only in December 1969 was presented to the 300-hour state resource bench tests, and the Shturm-V anti-tank missile system existed only in the form of mock-ups. In this situation, the leadership of the Air Force and the MAP made a compromise: they decided to eliminate some of the shortcomings identified by the mockup commission and during state tests later, and equip the first production helicopters with existing systems.

B-24 passed state tests from June 1970 to the end of 1972. Yu.N. flew them. Krylov, M.V. Razomazov and B.A. Shcherbina; the lead engineer was S.Kh. Atabe-kyan. During the tests revealed a lot of different "effects". In some modes, the so-called “Dutch step” made itself felt when the car, like a pendulum, began to sway along the course and roll. To eliminate oscillations, the wing was installed with reverse transverse V. At the same time, the ATGM suspension nodes were moved to its ends, because of their location on the fuselage in front of the UB-32А-24 units, unguided missiles from the blocks could collide with them during launch. Then they extended the crew cabin to ensure the normal placement of the new machine gun in the USPU-24 unit and the equipment of the 9P145 “Phalanga-PV” complex.

On hovering before leaving for a test flight to determine the accuracy characteristics of the NAR, the engines began to surge. The skill of the pilot Krylov helped to save the helicopter.

Tests on sandy soils revealed rapid wear of the blades of the first stages of the engine compressor and the leading edges of the rotor blades. The metal wiring of the latter literally before our eyes turned into an almost transparent shell and deformed, acquiring a shape far from the calculated one. All this caused a lot of trouble for designers.

Mi-24A from the 1970 installation release series


Gradually, the main shortcomings of the car were eliminated and it was considered suitable for use under the designation Mi-24. A special role in the implementation of the idea of ​​a combat helicopter in our country belonged to the Commander-in-Chief of the Air Force, PS Kutakhov. Under his direct leadership, all the modifications of the Mi-24 were given a start, he was well aware of the combat and flight characteristics of the vehicle, considered it his brainchild, and at times reported on the helicopter himself at shows of aviation technology to the country's leadership.

In 1975, on the lightweight version of the Mi-24 under the designation A-10, the crew G.V. Rastorguyeva set a number of women's world record for a climb, and three years later, on September 21, 1978, the test-pilot G.R. Karapetyan set a world speed record - 368,4 km / h.

    The car has already become a legend! ------ ,, Representatives of the Ministry of Defense, who were part of the mock-up commission, proposed to replace the subsonic ATGM with manual guidance mode with supersonic missiles with a semi-automatic missile launching system, and the GSh-23 cannon - with a 12,7-mm high-rate heavy machine gun created in Tula TsKIB SOO "---- but this was finally fixed and on MI-35 they returned to the turret with a twin 23mm, originally conceived by Mil.

      In Afghanistan, pilots complained about the insufficient firepower of a machine gun. I did not know that the idea with 23-mm guns is still alive. good

      By helicopter - Mi-24 has become such a recognizable machine that today it is firmly associated with the USSR and Russia. Original brand of the country. It is characteristic that even the newest helicopters are still awesome to him.
      Beautiful, formidable car.
      Personally, I strongly associate it with the war in the DRA, where this "flying armor" became a real "angel of death" or, as the dushmans called it, shaitan-arba. How many lives were saved for our soldiers by the fire support of the Mi-24 in the most difficult conditions.

      hmm ...
      Not certainly in that way...
      or even NOT AT ALL



      Mi-24VP - modification with a turret gun mount NPPU-23 instead of a YAKB-12,7 machine gun with a GSh-23L double-barreled gun. Mi-24VP (“product 258”) was produced from 1989 to February 1992. General production - 179 vehicles. The Mi-24VP artillery salvo with 213P-A and UPK-23-250 containers is second only to the gunship AC-130U Specter.



      Mi-24P (Hind F) - cannon ("product 243"). It was distinguished by a fixed U-260 installation on the starboard side with the GSh-2-30K twin gun. The machine gun and its sighting system were removed, since the aiming was carried out by the helicopter itself. Designed in the years 1974-1975. In 1981-1989, 620 helicopters were manufactured.



      Mi-24BM - modernization of the Mi-24V / P / VP. Fixed landing gear, Mi-28N propellers, all-weather avionics, Lipa active IR jamming station, NPPU-24 mobile unit with GSh-23L cannon, improved RK guidance equipment for Attack ATGM - Tor-24. Also Mi-24VM can carry ATGM "Baby", "Shturm" and "Falanga-M". UR V-V "Igla-V". First flight in March 1999

      as for ... the "new" Mi-35 ... it was produced during the Soviet Union times:

      • Mi-35 - export version of the Mi-24V.



      • Mi-35M1 - modernized. It features TV3-117VMA engines, French avionics, and a shortened wing. The composition of the armament is similar to the Mi-24VP.

      • Mi-35M2 - high-rise. It is distinguished by TV3-117VMA-SBZ engines.

      • Mi-35M3 - export version of the Mi-24VM.

      • Mi-35MO - night. It differs in the optoelectronic system GOES-342. In 2000, 2 helicopters were converted.

      • Mi-35P - export version of the Mi-24P.

      there is simply a "public play": the T-72 was upgraded - a super new T-90 appeared, the existing Mi-24s were modernized - the Mi-35 appeared (at the same time, they somehow completely forgot that even under the Soviet Union, export vehicles were designated by such an index)

    Therefore, instead of a mock-up, the commission was presented in February 1969 with the first prototype of a helicopter. Representatives of the Ministry of Defense identified a lot of shortcomings, made a number of comments and suggestions, but some of the flaws identified then forever "fit" into the car. And most importantly, what we lack now. The first B-24 took to the air on September 19 of the same year Alferov. This is a kind of Kalashnikov assault rifle in helicopter construction.

    Excerpt from article "... Hind is quiet, fluid, powerful and fast. And in the conversation after the flight, Staton and fellow Army pilot Steve Davidson made more admiring comments.
    "He is hardy like a tractor."
    "Put it in the barn for a year, then charge the batteries and you can fly right away. With our helicopters, this will not work."
    "It goes smoothly, just like 62's old Cadillac of the year."
    "Lubricate it well and you can fly it for hundreds of hours."
    Finally, Staton said what I think is the highest honor. One day during a conversation, he leaned back and said, "You know, if I wanted to fly a helicopter just for fun, there is no doubt that Hind would be at the very top of my choice" ... "

    A distinctive feature of the aerodynamic layout of the B-24 was the inclination to the right of the rotor shaft at 2,5 ° of the rotor shaft together with the power plant, caused by the desire to improve the accuracy of shooting from stationary weapons. This was due to the fact that the characteristic flight modes of the helicopter are hovering with a slight roll and flying with a slight glide caused by the need to balance the lateral component of the tail rotor thrust. Due to the inclination of the plane of rotation of the rotor, the roll and slip in all modes turned out to be minimal: roll - 0,5 - 1,5 °, slip - 1 °. To unload the tail rotor during flight at high speed, the end beam had a relatively large area (2,8 m2) and an asymmetric bearing profile. At maximum speed, the beam generates 67% of the lateral force necessary to balance the rotor torque.


    Still, smart people developed the Ka-50. They knew what an abomination such a tail rotor was.

    Abroad, the idea of ​​an armed helicopter was implemented in the UH-1H Iroquois helicopter, which was widely used in hostilities in Vietnam. He carried the soldiers and supported them with fire. But gradually, Western experts came to understand that the attack helicopter is only a platform for various weapons, and the landing of the landing force should be carried out by an amphibious transport vehicle, but also armed.


    Ours took another 20 years for this.

    But over time, it turned out that the Kazan hybrid creates significantly less cravings than the Mi-8 screw. The static ceiling at B-24 in standard conditions was 0,8 - 1,3 km. This was clearly not enough in the mountains of Afghanistan, where the combat helicopter yielded Mi-8MT with similar engines for take-off and landing and traction characteristics.


    But "the best in the world."

    Objectively, the main feature of the Mi-24 is its menacing appearance. Although something tells me that if a pair of Ka-52s, or even lousy European "tigers" are trampled on you, then your pants will be just as wet. For the rest, he completely failed in his concept of "shock transport".

      - transport and combat helicopter - Mi-24 throws the vanguard of the landing, which prepares a bridgehead for the landing of the main enemy forces;

      Still, smart people developed the Ka-50. They knew what an abomination such a tail rotor was.


      April 3, 1985, during the study of the maximum flight conditions on the Ka-50 prototype, as a result of exceeding the permissible negative overload by the pilot, the blades overlapped and the helicopter (tail number 010) crashed. The pilot (test pilot Evgeny Ivanovich Laryushin), trying to save the car, died.

      To prevent further such accidents, the distance between the main rotors was increased and a system was installed that made it difficult to control when the blades approached dangerously. To continue the flight tests in December 1984, the third instance of the B-80 (tail number 012) was created.

      In April 1985, the second prototype B-80 was first demonstrated to the top leadership of the Soviet Union at the demonstration of new aircraft in Machulishchi (Belarus). In preparation for this show, the creators of the helicopter were in for a deep shock. On April 3, disaster B-80 No. 01 occurred in which one of the best OKB pilots, Yevgeny Laryushin, died. When practicing accelerated escape from low altitude to the ground for an obstacle, as part of the study of the limiting flight regimes, the rotor blades overlapped, they collapsed, and the helicopter crashed.

      On June 17, 1998, General Vorobyov performed a flight according to the exercises of the Combat Training Course in conjunction with the program for mastering new aviation technology for R&D "Flight studies of the technique of performing complex aerobatics figures" and with the "Special program for training flight personnel to perform demonstration flights on Ka-50 helicopters" At the 30th minute of the flight, at an altitude of about 50 m and a speed of less than 60 km / h, in the process of an intense roll change by 116 ° and an energetic descent with a large dive angle, the rotor blades collided. The pilot died.

        extension
        A year before the disaster of General Vorobyov, another case of collision of the rotor blades on the Ka-50 was recorded. On July 31, 1997, when performing a hill, due to the pilot's loss of spatial orientation, the helicopter reached a pitch angle of 90 °, followed by overturning on its "back" and an increasing rate of increase in angular velocity to 180 deg / s. Fortunately, this time it was only the destruction of the tips of the blades, and the Ka-50, having completed an unintended loop, landed safely.

        It turns out, as tests show, that perfectly operational Ka-50s, driven by the most experienced of the most experienced pilots, regularly crash for the same reason: overlap of the blades during sharp maneuvering!

        Maybe this is only a trouble test machines and the flaw can be eliminated? No not like this.

        On October 24, 1969, due to the collision of the blades, the Ka-25 crashed, the crew of which, in the right turn with braking at low speed, exceeded the limit on heel angles by more than 3 times. On May 14, 1988, the Ka-27 was lost, the blades lashing out during acceleration to 350 km / h with a left roll of 70 ° and a diving angle of 60 ° (permissible values ​​are 290 km / h, 35 ° and 15 °, respectively).

        These are already combat helicopters. Nevertheless, the tendency to "overlap" with a sharp maneuver on them manifests itself in the same way as on the "Ka-50".
        For sea-based cars, this drawback is not terrible. There are no bushes and gullies on the sea. But what will the pilot do in battle if he jumps out on a “shaver” from behind a mound and suddenly sees a MANPADS rocket going directly into his forehead or tracer bullets of a heavy machine gun? Naturally - will try to leave the affected area at the limit of possibilities. That is - he will make the very sharp maneuver that causes the overlap of the blades and the death of the machine. It’s a paradox, but to destroy the Ka-50 it’s not at all necessary to fall into it. It is enough to scare an inexperienced combat pilot unexpectedly.

          One of the most dangerous enemies of combat helicopters: the heavy machine gun. When firing at the blades, pulling out their pieces, it changes all the properties of the HB. So, the Mi-24 single-rotor helicopters in Afghanistan repeatedly returned from such situations to the base with one blade partially or completely torn out. "Ka" with twin propellers in such a situation is completely DOED - it enters the mode of uncompensated rotation directly over the battlefield with fatal consequences clear to all. The coaxial propeller, as already mentioned, is a well-balanced aerodynamically symmetrical system. Because of this, it is "easier to manage". The imbalance makes the system inoperable. For coaxial helicopters, in the event of combat damage to the blades, it is necessary to consider not the dynamics of the behavior of an isolated (damaged) main rotor, as in a single-rotor design, but the dynamics of a system of two main rotor.

          And this is not counting the fact that the “Ka” sticks up a meter upwards on the coaxial screw: the thrust is five times more than the affected area than the Mi-28NM, 8 times than the Mi-24VPI. One KPV bullet or 20mm shell in APNV traction - and a khan to a helicopter.

          According to the stories of helicopter pilots, the Mi-24 remained manageable even with the tail rotor completely shot off. At speeds above 200 km / h, the oncoming air pressure does not allow the tail boom to “overtake” the car and it can fly “in an airplane”, get to its native airfield and even sit down, as the pilots say, “with braking about the hangar”.

          "Ka-50" in case of damage to HB immediately die directly above the battlefield.

          Kamov’s helicopters (co-pilots) are good as sea ones: fly yourself in a straight line or fly ... now let him use it at sea.

            Suppose you are likely to translate the aligner into uncontrolled rotation, although I don’t understand how to do this by shooting the blade. This will lead to a change in lift, but the motors both rotated 2 hefty rotors and will rotate with opposite active moments, the mass of the blades is relatively small to create a serious difference in the moments. That is, someone has problems with physics.

            How many ways to translate the classics into left rotation?
            1) Hit the tail rotor.
            2) Hit the tail boom and the thrust of the screw. This is a rather big goal.
            3) Damage to the tail rotor in a collision, as already noted in Vietnam.
            4) Any breakdown of the screw rods without combat damage.

            But still strong gusts of wind lead to disasters.

            Oh yes, if the helicopter jumped out of the bushes, and towards the rocket, well, commanders under the tribunal. If a helicopter is found, then it will live for 14 seconds, anti-aircraft guns will be taken away, but only ours continue to proudly fly over the battlefield, since they simply do not encounter anything more serious than MANPADS.

            Kamovtsy did not hesitate to use the most optimal scheme if they believed that it would be better for a particular vehicle, but for some reason it was the Ka-60, whose task is simply to fly along the route, was made a classic (cheaper and less fuel is needed), and combat co-axes. And where is our MO looking? The Ka-50 has existed for 30 years, during which time it was possible to perform any tests of combat survivability and reject it if unrecoverable flaws were found. So what? Where are these shortcomings, not the speculative, that "where has it been seen that a combat helicopter was two-story", but quite specific test results? Or can knowledgeable people immediately understand the absurdity of raids? And about all sorts of myths, it is enough to remember that 99% of the people believe that a tank with a diesel engine is less fire hazardous than with a gasoline engine, although in real life a projectile sets fire to diesel fuel as easily as a match gasoline.

          As usual, the Milefans are blatantly lying. From the overlap, only the machine under the control of Voroviev was lost and one prototype after which the distance between the blades was increased. Over the entire period of operation of the aligners (I’m not considering the Ka-10, it’s still growing and growing until a full-fledged helicopter), it’s not lost due to the overlap of a single car without violating the requirements of the RLE.

        As usual, Milefans prefer to keep silent that the waving of the blades is characteristic of all types of helicopters and the classic stably cuts its tail beams with subsequent uncontrolled left rotation.

        And Vorobyov died in general at a window dressing; in normal operation, it is forbidden for any helicopter to enter such modes. And the findings of the US military on the use of helicopters in Vietnam indicate that damage to the tail rotor as a result of collisions with trees and fire from the enemy.

            If the Americans were not able to create a serial ally, although they tried, then this is their problem. In the case, I said everything, but someone has problems with physics. I can also add that the Ka-52 even surpassed the Mi-28 in the number of machines ordered, which everyone can’t bring to mind.

            In the world, for example, there are no production aircraft in the Su-27 weight category, except for the Su-27 itself and its derivatives, we will announce that this is only our nonsense, an airplane is not cheap, especially when it comes to kerosene, and the inertia is higher, or all -so think about why it exists?

        That is, the Mi-28 and Ka-52 also carry passengers?

        for starters: the Mi-24, by classification, is a military transport helicopter, not a pure GP. according to the idea of ​​Mikhail Leontyevich Mil, there should have been a triad:
        - attack helicopter (VOP) - Mi-28. "clears" the site from the foe;

        - transport helicopter - Mi-26 throws the main landing force.

        and it is not a fault that the country did not pull the entire "triad" at the same time. and for many years the Mi-24 was used as a GP.


        1) Proof will be?
        2) With regard to the Ka-50, milfans like to poke at that they say no one does that, about the fact that all over the world helicopters are either combat, or transport (albeit with weapons sometimes), and only here they invented a "flying BMP" as usual, they shyly keep quiet.
        3) The machine is created for certain tasks, if it does not perform them, then what for it is needed. How about the Mi-24?
        a) Transportation of the landing. It has never been used. That is, the file is unique. For the sake of this function, the helicopter carries a huge additional weight of the cargo compartment ..
        b) Fire support. That was the only thing I did. Did he do it well? Well, no machine in itself is neither good nor bad, it can only be better or worse than similar. Was there a similar car in the USSR? No! That is, there is nothing to compare with. In the United States, the purely combat AH-1 and AH-64 were successfully used. All sorts of "Iroquois" and "Chinooks" drove the soldiers without any problems. All these machines are still in service, but the Mi-24 in the Russian army is being supplanted by the newer Mi-28 and Ka-52 of the same class, which are built on the same engines. Our people admired how, in the difficult conditions of Afghanistan, the Mi-24 sometimes could not even take off with a full load of ammunition, let alone a landing force and they were replaced by armed Mi-8s. The idiocy is that if initially they did not suffer from garbage, but made a normal combat helicopter, then they simply would not have to create the Mi-28 and Ka-50, and it would be much cheaper. The allegations that the country did not pull there are just ridiculous. When not pulled get rid of the least important. Moreover, the country had one of the most massive transport helicopters in history, why duplicate its functions ?? Moreover, designers in KB fight for every kilogram of weight and any added functionality should be very seriously justified.

    I will get into a dispute of respected colleagues Avenger711 and smprofi.
    The Ka-50 was tested in combat conditions in Chechnya. The results were published, including the internet (google colleague smprofi). Quite an interesting story of pilots. Even the video in YouTube is about this business trip. The Kamovskiy helicopter turned out to be more efficient and maneuverable than the Mi-24, with which it flew in tandem. Where the Ka-50 could fly, alas, the Milevsky helicopter could not always fly.
    There were combat damage, including damage (backache) of the blades. However, the Ka-52 nirazu did not fall, and each time returned to Mozdok.
    It’s not for nothing that the Ka-52 was identified as a field of application: in the mountains, to support special forces, including in settlements, and as a command vehicle for a group of helicopters.
    In Soviet times, the Mi-24 (Mi-35) produced nearly 3500 vehicles. The Mi-24 was cheaper to produce in the production of infantry fighting vehicles. This was one of the reasons, if not the main one, because of which pure attack helicopters (VOP) were not produced.

      Gamdlislyam, thanks for the intelligible comment. flattened as he could.
      Do you still agree that the Mi-24 and the same Ka-50 / Ka-52 are of a different class of machine? and, frankly, it is not correct to compare them. one can compare the Ka-50 / Ka-52 with the "classmate" Mi-28.
      As for the possibilities of the "classic" and the coaxial scheme - I admit that the possibilities are different. it would be amazing if they were the same.
      about the damage. in order to judge, you need to know about them in detail, about their nature.
      I don’t believe the stories told by the pilots on camera. what is needed - then they will say. there is no opportunity to communicate in person, "without a protocol". other pilots, on the same camera, excitedly talk about the Mi-28 (after the Mi-24).
      Avenger711 threatened heavenly punishments for the "classics" in case of damage to the tail rotor or beam ... here is an example from Afgan (here, on topwar there was a series of articles "Turntables", Afghanistan. MI-24.):


      Consequences of the incident with the helicopter of captain Nikolayev from 262-th EIA. After being hit by a DShK bullet, the helicopter lost track control, but managed to sit down and already on the run drove into the hangar. The car was seriously damaged, but soon returned to service, Bagram, March 1987 g

      well, at the end. above was information on co-axes and their falls. it is still a reality, not a "sensation" sucked out of the finger.
      and quite finally: there is no perfect weapon. as there is no perfect helicopter (airplane, tank, etc.)

        Do you still agree that the Mi-24 and the same Ka-50 / Ka-52 are of a different class of machine? and, frankly, it is not correct to compare them. one can compare the Ka-50 / Ka-52 with the "classmate" Mi-28.

        Of course. These are not only cars of a different class, but also belonging to different generations. Indeed, you are absolutely right, the Ka-50/52 needs to be compared with the Mi-28. But the appearance in the army of these two machines was facilitated by the rich experience that they gained during the operation and combat use of the Mi-24.

          not really. Mi-28 was conceived by Mil himself. maybe the configuration has somehow changed over time - maybe. but the idea itself is old.

          Gamdlislyam, during the discussion, the "little nuance" is somehow completely forgotten: designers / industry can create anything, but in the army all this will appear only if the army (represented by the GRAU) gives money for the acquisition (and for development too , especially in the days of the Union).

            I agree with you, without an order, you won’t get money for development and experimental construction. Today, not even in Soviet times.
            In contrast to modern times, in the USSR, although they did not advertise, almost all the developments in military aviation were competitive. The same Mi-24 won the competition at the Kamov machine.
            While the Milev Design Bureau was busy with the Mi-24, the Kamovites worked on the prototype Ka-50. And when (taking into account the experience of Avgan) a competition for GP was announced, the Kamovites were ahead ..

          You do not confuse classes and generations. The T-34-85 and T-54 tanks belonged to the same class, but to different generations. But the PT-76 and T-54, although one generation, but the classes are different.
          MiG-29 and its half FC-1 (aka JF-17) belong to different classes and, possibly, to different generations. I don’t know the quality of the FC-1 electronics, maybe better than that of the MiG, since it’s newer. But he is undoubtedly in the same class with the Indian HAL Tejas, Gripen and such classics as the MiG-21.

          Mi-24 and Ka-50 with Mi-28 have approximately the same take-off weight and the same scope. More precisely, the Ka-50 has a specific tactic, but the Ka-52 is not different from the Mi-28 in this regard. So these are cars of the same class.

        Helicopter directional control is carried out using a swashplate, it is not clear what is more classic here.

      If they had made a single-seat version of the Mi-28, then it would also fly where any other combat turntable of the same class on the same engines would pass.
