Need for speed: projects of promising high-speed helicopters

The CV / MV-22B convertible is adopted by the US Marine Corps in the 2007 year. This is the only currently operated aircraft, taking off and landing vertically and having a high speed horizontal flight.

Helicopters since their appearance in the French army and air force during the war with Algeria in the 1954-1962 years added a new dimension to the concept of military operations.



The use of helicopters to support vertical maneuver allows you to deliver combat units, not paying attention to geographical obstacles, to the place where your opponent can least expect. This opens up new combat opportunities. Since the time of the Algerian conflict, technical progress and constant improvements in the design of the helicopter have increased its capabilities, in particular, its payload and lift. However, the maximum speed and range of modern medium and heavy multi-purpose helicopters, apparently, reached their upper limits.

For example, the newest model F of Boeing’s CH-47 Chinook multi-purpose transport helicopters has a maximum speed of 315 km / h and an 370 km range. For the CH-47F is the Russian Mi-35M helicopter with a maximum speed of 310 km / h and a range of 460 km. The AgustaWestland / Finmeccanica medium AW-101 helicopter with a maximum speed of 309 km / h, while the new AW-139M medium helicopter of the same generation develops a maximum speed of 306 km / h. As can be seen from this list of maximum speeds, not all modern helicopters can develop a maximum speed of just over 300 km / h.

Cruising speed is important because it affects the "turn" of the aircraft when performing combat missions. The faster the helicopter flies, the sooner it will reach its goal and will soon be able to return to pick up and deliver additional forces and supplies. Rapid build-up of forces on the ground is very important for the success of the air assault. Thus, the ability of an aircraft to fly more flights over a given period of time is extremely useful. Flying at high speed also increases survivability by reducing the time when the aircraft is open to enemy observers and arrows on the ground.

An increased range is also desirable, although it is mainly related to the fuel supply. In the past, special attention was paid to increasing the flight range, which is directly related to the capacity of the fuel tanks. Medium and heavy helicopters, such as the Mi-26 with a range of 800 km and Sikorsky CH-53E with a range of 999 km, need such a range to perform several sorties without refueling. Meanwhile, fuel booms mounted on aircraft, such as the CH-53E helicopter or the MH-60G / U Blackhawk special operations helicopter, allow you to perform long-range tasks in the rear of the enemy. However, the range and cruising speed of flight in terms of practical operational sense are closely related. Although the aircraft may have a range that allows it to reach the landing area hundreds of nautical miles, it is necessary to take into account the return journey and the time spent on it, since this can lead to an increase in the time it takes for the landing forces to rise. In this case, it will not be able to quickly perform round-trip tasks due to the increased flight time. That is, in order to most effectively use a longer range, the aircraft must again fly faster.

Swivel screws

Despite initial difficulties and criticism of skeptics, the Bell-Boeing CV / MV-22B Osprey tiltrotor, which began life in 1981 in the framework of the Vertical Take-Off / Landing Experimental (JVX) joint project, changed the concept of operations involving vertical-lift devices. First deployed by the US Marine Corps in 2007 and special forces of the US Air Force in 2009, this convertoplan is currently used not only in military operations (intervention in Iraq and Afghanistan), but also in humanitarian tasks and disaster relief operations, for example he helped out after typhoon Haiyart, which devastated part of the Philippines in 2013. The Marines, in particular, saw in the MV-22B tiltrotor a solution to the problem of delivering troops from ships far beyond the horizon. This task was previously performed by a heavy CH-46E Sea Knight transport helicopter, but its flight time was unacceptable. This helicopter took quite a long time to build up the necessary contingent of airborne forces, while it made several sorties. The limited number of troops remained vulnerable.

The unique characteristics and capabilities of the MV-22B tiltrotor are aimed at solving such problems. He can take off vertically from the amphibious ships, but when moving to level flight and turning the engines down he can fly at a speed of 500 km / h. This is more than twice the speed of the CH-46E helicopter, which means the flight time is reduced to the same landing zone by more than half. Plus, the large 722 km range and higher payload in the 9070 kg cockpit and on the 6800 kg suspension further increase its efficiency. The hands-on experience gained with the MV-22B has increased interest in the convertoplanes as an aircraft type and improved the prospects for the next generation convertoplane. This is especially true given that CV / MV-22B, in fact, uses the technologies, materials and processes of development and production of 70-ies of the last century, which, without any doubt, have advanced significantly over the past three decades.


When developing a promising V-280 Valor convertible, Bell-Boeing takes into account the experience gained with CV / MV-22B and introduces the latest technologies, materials and production processes in order to create a more sophisticated turning screw aircraft.


For the Sikorsky S-97 helicopter, a scheme with two rotors of opposite rotation and a tail propeller is used. This allowed not only to get high speeds, but also the possibility of flying sideways and even back

Perspective development

As noted above, aviation the industry is working to overcome the maximum speed limit of helicopters. The problem of increasing speed is partially connected with the very element that allows the helicopter to make a vertical flight - with the upper rotors. The problems that needed to be solved were related to the aerodynamic drag of the screws and the casing, elimination of air breakage from the blades, reverse air flow, and air compressibility. A discussion of the technical subtleties of these problems could take several pages, but one thing is obvious - they must be solved in one way or another in order to change the dynamics of the helicopter flight. Designers are trying to solve these problems, going in a variety of directions and "groping" for answers there.

For example, Bell Helicopter took the proven concept of CV / MV-22B pivot screws and adapted it for its convertible plane V280 Valor project. According to Steve Matia, director of business development for advanced rotary screw systems: “When creating and producing the V-280, the experience gained and tested on the CV / MV-22B tiltrotor is used, and the most modern development and design technologies are used.” As he explained, one of the most interesting solutions is implemented in the V-280 gondola. At the convertoplane CV / MV-22B, the entire gondola is rotated. With the new V-280, only the screws and gears are rotated, while the gondola and the engine remain stationary. This allows you to safely embark and disembark, since the engine case does not interfere with the landing party, and also reduce maintenance requirements. The V-280 convertoplan, designed to perform various tasks, is smaller than the CV / MV-22B convertiplane. It will have a cruising speed of 520 km / h, combat range over 930 km, will be able to hover at an altitude of 1828 meters and fly at a temperature 32 degrees Celsius with a full combat load, while exceeding existing helicopters in maneuverability. Together with Lockheed-Martin, Bell offers a convertible glider V-280 for the FVL JMR-TD (Future Vertical Lift Joint Multi-Role Technology Demonstration) advanced helicopter program. The companies have scheduled the first flight of their convertible V-280 on August 2017.


Through the use of tail pusher propeller and twin-girder tail stabilizers, the S-97 is already noticeably quieter than traditional helicopters. When there is no need for high speed, but low visibility is needed, the pushing screw makes it almost silent.




A promising X3 helicopter from Airbus Helicopters has short wings, creating lift at speeds above 80 nodes, and two turboprop engines for forward flight. Pilots speak favorably of the maneuverability of an Airbus Helicopter aircraft.

X2

Meanwhile, Sikorsky and Boeing have joined forces with the FVL JMR-TD program to offer the SB-1 Defiant helicopter. They propose to take Sikorsky's X13636 project with coaxial screws of opposite rotation and a pushing propeller as the basis for a new aircraft weighing no more than 2 kg. In this approach, Sikorsky-Boeing has its advantages, since the sample for demonstrating technical solutions X2 Technology Demonstrator weighing 2720 kg made several test flights in 2010 year, in which it reached a record speed of 463 km / h. In 2015, the company Sikorsky presented its prototype of a light tactical multipurpose helicopter S-97 Raider weighing about 5000 kg.



The project of the SB-1 Defiant helicopter companies Sikorsky and Boeing

Chris Van Van Buyten, Vice-President of the Innovation Projects Division at Sikorsky, who heads this project: “Flying farther and faster in a co-axial helicopter is definitely a key requirement. However, with our S-97 project, we want to show the next-generation rotary-wing aircraft, which will be able to surpass traditional helicopters in each operational parameter, especially at low speed and during a hangup. The secret of the coaxial unit X2 is that the main screws with counter-rotation provide lift and forward flight without a tail screw. Above the 150 knots (277,8 km / h) the thrust is provided by a pushing screw, so the main screws do what they do best - provide a lift. ” Van Byuten further made the assumption that the S-97 and SB-1 aircraft "will radically change how military pilots are now flying and fighting in helicopters." By the time the Sikorsky and Boeing team has raised its SB-1 helicopter into the air in 2017, Sikorsky will have the third experimental device X2 in less than 10 years, which can finally confirm the inherent ability of this project to scale to the size of an average multi-purpose UH helicopter -60 Black Hawk.


Sikorsky's X2 Project


The goal of the FVL JMR-TD program is to develop and deploy an aircraft with significantly improved performance and capabilities that can perform a wide range of tasks, ranging from reconnaissance and attack to transporting troops and cargo.

Hybrid projects

Airbus Helicopters (formerly Eurocopter) is implementing a hybrid approach to developing advanced helicopters using some of the integral elements of traditional aircraft, such as short rectangular wings. This solution significantly increased the flight speed, which in 2012 showed a test flight of the technological demonstrator X3, which reached the speed of 255 nodes (472 km / h) (above the speed record X2). In the X3 project, the top rotor for lifting and hovering and short wings are combined with turboprop engines mounted on them, providing thrust for moving forward (therefore, the term “hybrid” is used here). It does not have a rear propeller; instead, a horizontal stabilizer with vertical tail stabilizers at each end is installed. When flying forward at speeds of more than 80 knots (148 km / h), the wings begin to create additional lift and at high speed provide almost all lift for this aircraft.

Airbus has not yet disclosed its plans for a new military aircraft using the approach shown by the X3 project. However, a company representative suggested that many of the current helicopters could include these constructive solutions. Since the deep-modernized body of the AS-3N365 Dauphin light-duty helicopter AS-3N3 from Airbus Helicopters is taken as the basis for the X3 project, this seems entirely possible. X2019 was shown to the US military, but ultimately did not get into the FVL JMR-TD program. Airbus has indicated its intention to focus on search and rescue tasks and continues to work on an aircraft based on the XXNUMX project, which can take to the air in the XNUMX year.

Rachel

The Russian Helicopters holding announced in 2009 year that it is developing a promising high-speed aerodynamic helicopter with a retractable landing gear and a proprietary implementation in the rotor design of the local stall suppression system on the retreating blade SLES (Stall Local Elimination System). According to the company, Mi-X1 will have a cruising speed of 475 km / h and a maximum speed of up to 520 km / h. In August, the 2015 of the year at the MAKS Airshow in Moscow Helicopter Plant. Mile showed a RACHEL demo (Russian Advanced Commercial Helicopter - Russian advanced commercial helicopter), advertised as a high-speed helicopter. The helicopter can take on board up to 24 passengers or 2,5 tons of cargo and carry it with a maximum speed of 500 km / h to a maximum distance of 900 km. The holding said that test flights will begin in December, and mass production in 2022 year. In December 2015, the public was presented a deeply modernized Mi-24K with new curved rotor blades. The purpose of this development is to reduce aerodynamic drag, increase stability and speed of flight of the helicopter. The company assumes that the maximum speed of the experimental aircraft will increase from 333 km / h to 400 km / h. According to the company, if it is possible to re-equip another aircraft with curved blades, this will increase the speed by 30 percent.

X-PLANE

The small American company AMV is developing its own high-speed vertical take-off vessel with propellers located on its short wings. The prototypes clearly hint at a combination of a VTOL (Vertical Take-Off and Landing) and a high-speed helicopter. AMV launched its demo X-PLANE into the air and expects its AMV-211 to reach a maximum speed of 483 km / h, a cruising speed of 402 km / h and a flight range of 1110 km. Although the company submitted its proposal for the FVL JMR-TD program, its project was not selected, and the X-PLANE project was not stopped and its development continues.


AMV X-PLANE Concept

Driven thrust

Another candidate proposed in the field of high-speed helicopters uses the VTDP patented design scheme (Vectored Thrust Ducted Propeller; a pushing screw with thrust vectoring) mounted in a pipe in combination with bearing wings. The experimental four-bladed X-49 Speed ​​Hawk model with two engines for the first time took off in the 2007 year and reached the speed of 268 km / h. This model was based on the body of the deck anti-submarine helicopter Sikorsky SH-60F Seahawk. The work was initially funded by the US Navy and then by the US Army to demonstrate ways to increase the speed of existing helicopters to 360 km / h. This project was not selected for the FVL JMR-TD program.

SB-1 is a further development of the Sikorsky S-97 project and another candidate for the FVL JMR-TD program, which aims to meet the needs of an average multi-purpose helicopter

Mind prevails

A number of countries, including the US and NATO forces, will face the challenge of aging their helicopter fleets in the coming decade. Many of the current helicopters were put into service in the 80-s, their lifespan is approaching the 30 years. For example, McDonnell Douglas / Boeing AH-64 Apache combat helicopters began to be supplied to troops in the 1986 year, and despite a number of improvements, they have essentially the same flight characteristics. The UH-60 family is even older; the first helicopters were delivered in the 1974 year. The newest UH-60M helicopters have electric remote control systems, a common architecture, a new powerful and reliable engine, but the speed remains the same. The first task of the FVL JMR-TD program will most likely be the replacement of UH-60 series helicopters, which explains the similarity of the structures of the cabins offered for it.

So, military operators inevitably seek to replace their aircraft. And here they are faced with the question of whether to leave proven designs, albeit with the inclusion of digital electronics and avionics, electrical remote control systems and composite materials, or move to projects that offer a new level of possibilities. The second question is the possibility of developing a universal vessel that could perform a variety of tasks. The US military initially wanted to have a maximum of three aircraft to perform all its intended tasks. This idea has changed several times, and at the moment they are focused on three projects: Light Scout light helicopter (operated from 2030 of the year), medium Medium Light, universal / shock from the beginning of operation from 2028 of the year, and finally heavy Heavy Cargo transport from start of operation from 2035 year. In addition, the US Army is counting on the implementation of the Ultra project, the start of operation of which is scheduled for 2025 year. This is a new vertical take-off truck with characteristics similar to those of transport aircraft with turboprop engines, such as the Lockheed Martin C-130J or the Airbus A400M. But, judging by the results of a briefing by José Gonzales, deputy director of the ground combat and tactical combat systems department, held at the US Department of Defense in January 2016, everything seems to be changing again. A breakdown into categories is proposed, based on necessary capabilities rather than mass. These new categories have not yet been announced.

Even without the “Ultra” option, this concept of new aircraft has not only technical problems, but can also affect the current situation of the US Air Force with its ambition and deadlines. Probably, from an operational point of view in various tasks some projects may be preferable to others. The main issue remains the proportionate funding of such a program and how this may affect other army modernization projects.

Fly forward

The CV / MV-22B tiltrotor operating experience reveals the advantages of this aircraft and points to new ways of using its unique capabilities. Based on this experience, the US command of special operations forces USSOCOM has already expressed interest in increasing the number of CV / MV-22B convertible plans compared to initial requirements. Adequate experience of the X3 project in the framework of the FVL JMR-TD program shows the reality of achieving high speed, increased maneuverability and greater range. Currently, there is a question of determining the viability, expandability and adaptability of high-speed helicopters, as well as their cost, which will allow them to perform the full range of combat missions. High-speed helicopters are already on the horizon, but how soon and in what form is still unknown.

        Experimental developments in the described areas have been going on for a long time. According to the information available on this subject, the graduation project was defended at the Moscow Aviation Institute in 1936. In Germany in 1938, the Weserflug P.1003 convertiplane project was also developed, but it was not implemented. The American XC-142A flew in 1964. A little later, the Bell X-22A, the Canadian CL-84 and the French Nord 500 Cadet flew. We have been developing quite actively since the beginning of the 70s, but the MI-30 project died due to the collapse of the country. Propeller-driven helicopters have been developed from the late forties. In the fifties in Mil Design Bureau created an experimental car - B-7. But even the latest designs like Osprey cannot be considered perfect. A number of unresolved issues remain and whether they will be resolved permanently is not clear.

          True, but the B-7 is still not the ramjet, which they were actively trying to use, like the Americans in a small series of Hiller Hornet. On the B-7 stand turbojet.

          True, Bell admits that only the work of F.P. Kurochkin helped them create the V-22 in theory. But what is the design, because of some "misunderstanding" of the basics of the tiltrotor ??? Triple duplication for all systems, but in constant work - you must agree, this is a clear overkill IMHO!
          I’ll try to clarify, on this thread I don’t want to duplicate, but next to it https://topwar.ru/98278-na-novom-vitke.html# (due to ignorance of the existence of an interesting topic) I have already posted some material. The work, in general, is still experimental - but there is a result! smile

            This V-22 has a large number of accidents and a lack of pitch control. In terms of rationality, reliability and convenience, much earlier Canadian convertiplanes are qualitatively superior to them.

                  A distinctive feature of the new machine was the fact that for the first time in the world the technical idea of ​​a rotary wing was successfully realized in it. Previously, such machines were called rotorcraft, but they can also be attributed to the class of "tiltrotor". Structurally, the apparatus, then called VZ-2, was a monoplane with a highly located wing mounted in its central part, with an open truss fuselage and with a three-leg landing gear with a nose strut and a tail wheel. He had a pilot's cabin with a spherical flashlight from the Bell 47 helicopter, behind which were the Avco Lycoming YT53-L-1 gas turbine engine and transmission.
                  .....................
                  The S.P. Langley Research Center worked with the VZ-2 A until 1965. During the operation on the device, about 450 flights and 34 complete transitions from one mode to another were performed. Currently, the device is on display at the Smithsonian Institution.

        Nothing good - the Americans just just smashed it on purpose ... supposedly trying to break the F-4 climb rate record to 10 feet.
        The second was broken by them while trying to get into a storm on the UDC "Guadacanal"
        During the tests (experiments), the Canadians lost only one, due to a bearing out. The interval between the Canadian accident and the American "tricks" is eight years, before that everything worked fine.
        Such actions by the United States to sabotage and deliberate bankruptcy of firms (this opusiti game its shares on the stock exchanges) have led to the fact that until recently, only one France possessed an independent aviation industry in the Western world.

Convertoplanes require a very serious study of stabilization and stability systems! Osprey was created for about twenty years, and this time was spent, not in the least, on the development of algorithms and their electronic implementation. Then, in the seventies, the possibilities of electronics did not allow the development and creation of a control system. And any helicopter cannot fly without automation.

      Over 25 years before Osprey there was such a device ...

      At the same time, a number of convertible plans of various American companies appeared: the topic was fashionable, the US Air Force promised to buy everything that would pass at least the initial tests, and the engineers gladly plunged into work. One of the most original designs was the Bell X-22A not with two, but with four YT58-GE-8D engines with a total power of 1250 hp. For the first time in the short history of such machines, the screws on this convertoplane were placed in circular covers, which significantly increased the efficiency both in vertical movement and in horizontal flight. The first of the two Belles made crashed (the pilot survived) during landing at an early stage of testing, but the second successfully flew from 1966 to 1988 for a year, although the model did not go into mass production.

              But Canada has a number of very significant drawbacks:
              1. Multimotor, especially strongly spaced along the length of the wing - without a synchronizing shaft (and it is not on the Canadian one!), In case of failure of one of the cantilever engines, an accident cannot be avoided, overturning the moment along the bank.
              2. The small diameter of the aircraft-type propellers, and, consequently, the congestion of the VMU on takeoff and hovering during helicopter mode.
              3. The above requires excessive fuel consumption.
              4. And very significant from a commercial point of view, the inflated cost of SU.
              5. A solid increase in the mass of the empty, due to the hardening of the wing and the complex node of its suspension to the fuselage + the mass of the rotary mechanism of the wing ....
              And this is not all the disadvantages. winked

              Here is a confirmation of my words:
              In 1972, the pilot Canter CLV-84-1 VTOL was transferred to the US Navy Testing Center for final flight tests during the year under the fleet program of the USA, Canada and England. Tests have shown that the overall efficiency of the CL-84, expressed in kilometers per hour of flight for typical search operations, is two and a half times greater than that of a search helicopter of that time.

              I did not go into the series, and also "this"

              During the flight tests on September 12, 1967, the experimental CL-84 VTOL crashed, the crew ejected. The aircraft lost control during a maneuver in horizontal flight at a speed of 275 km / h at an altitude of 900 m. Before the accident, the aircraft made 305 flights and flew 405 hours.

      First of all, it is necessary to correct the consciousness of the aircraft customers themselves. The use of a large-diameter helicopter propeller for the purpose of obtaining high flight speeds itself is not very rational, they are needed only in the take-off-landing mode, for the economy of these flight operations. Another thing is the efficiency of the flight itself, in order to increase the flight range and (or) increase the mass of the transported payload. The principle is especially vivid here: "the quieter you go, the further you'll get", that is, a decrease in the cruising speed of a tiltrotor flight squared (or more) reduces fuel consumption, in a purely helicopter scheme this dependence does not work so clearly, because the specific fuel consumption for the function of maintaining the helicopter in a vertical plane increases. By the way, the noise (stealth) Also, it is always necessary to search for the optimal form of application of various aircraft.

          The main problem of any tiltrotor is the design of the propellers. The fact is that there are some requirements for the main rotor, and others for the main rotor. When trying to combine the desired characteristics, we get losses in both. Therefore, it is not very clear why in the concept of convertiplanes preferred propellers rather than jet engines. True, for stability on takeoff there should be four around the perimeter.

            in principle, you are right. In a helicopter circuit, the weight under the center of the large propeller is stable, and the efficiency of the propeller in statics is large. In the aircraft - the screws are also good because they allow you to blow the wing already at zero speeds. A tiltrotor is neither this nor that. But still, on a vertical take-off, the screws are more profitable

      So, according to the Russian Helicopters, instead of the net speed that was supposed to be pursued earlier, priority was given to economic efficiency and environmental friendliness. There will still be a speed increase, but it will be approximately 25% compared to modern counterparts, and not 50 or 100, which were assumed by high-speed helicopter programs (note that they will continue to exist, but as separate projects).

                There is no analogy with a gyroplane. The high-speed helicopter pushing screw replaces the horizontal thrust component of the main rotor of a conventional helicopter. The speed gyro rotor generally obstructs.

                There are gyros in which, for take-off from a place, the main rotor spins on the ground, but these are not high-speed helicopters.

    Honestly, these hybrids with a complicated transmission are critical. Few disasters and problems of operation of prototypes of 60-70s? They themselves suffered with rotorcraft no less.

    Maybe you should pay attention to short take-off and landing planes, such as the same An-14 Bee, but aimed even at high-speed capabilities, i.e. with increased specific power and wing mechanization. The problem is quite non-travial, of course, it turns out, namely, to ensure extremely low take-off and landing speeds and at the same time provide excellent controllability in these modes with resistance to lateral gusts of wind. Roughly speaking, an airplane should have a low specific gravity and wing load, be able to parachute like a Bee or a Storm, and at the same time bend the speed of the convertiplane.

    Why is it that they have little to do on this topic, probably the cuts are too small? Although there is a need for them, even in the civilian sectors, it will be even more expensive to operate, but cheaper and more reliable than a tiltrotor definitely.

          No, there’s a trick in highly optimized aerodynamics and wing mechanization, plus power ratio. It’s just that most of the tasks were not set at speeds of 300-400 km / h, and their operating costs are cheap. Well, UVP aircraft also deliver cargo to hard-to-reach areas, so this is almost the norm for them. The same Po-2 of WWII was essentially a UVP aircraft, and it brought a lot of benefits in this capacity.

          So I think that these convertiplanes-hybrids-gyroplanes and other crossbeds of hedgehogs with snakes, for the sake of GDP, lose a lot in load-bearing capacity and reliability, because any technique is a fabric from compromises, and at the same time we will get a useful machine in the national economy.

              Not necessarily, you can compensate for the low wing load like the An-14.



              And now An-28 in Africa is annealing.



              Although biplanes are also excellent devices in this regard.

                Low wing load - implies a large wing area. That for the military is not entirely acceptable.

                The ability of a high-speed helicopter to hang and take off vertically - no short take-off will provide. Since at least some but still runway is needed.

                  Well, Duc, I’m talking about this, if there is so much hemorrhoid with this GDP, and if there are helicopters for these purposes, then why bother? Roughly speaking, send an assault group of the helicopter to capture a relatively more or less suitable site and already send a UVP transport aircraft for various needs. And in general, if the military outline the dubious prospects of a tiltrotor, I think about a large wing area will become more accommodating.

                      In general, an aircraft carrier should turn against the wind to launch aircraft. Hercules is an oldish aircraft, with not the highest power ratio and not the most modern wing.

                      I understand in the video that many planes are lightened to the limit, but on the other hand, the development of the aircraft wing has not yet ended if we go in the opposite direction from the supercritical profile. I mentioned below slotted wings, which are close to a highly mechanized wing with slats and flaps, as there are options for wings with blowing from GTU compressors, just to prevent flow stall, which often happens at low speeds and large angles of attack.

                      I understand that the UVP plane will not look so pompous as a tiltrotor, yes, it cannot make a purely vertical landing, this is a compromise. Like a compromise, high-speed helicopters with special blade profiles, but they do not exceed the threshold of technical complexity, limiting mass application. A rotary hovercraft and a rotorcraft belong to such schemes and this is their problem, there will be no passenger or mass transport vehicles for this reason.

                        The mechanization of the wing and the take-off power of the C-130 engines were not initially sharpened for GDP with a length of 250 meters (the run length at normal weight of 1433 meters is indicated in the LTX).

                        If you equip the C-130 with new wings with slats and flaps located all over the span, as well as install engines with twice the take-off power, the run distance with a normal weight will be reduced to the required 250 meters.

                        Nothing prevents the development of the Russian line of similar turboprop aircraft of various carrying capacities, which would perfectly fit not only as military transport carriers, but also as economic aircraft in the Arctic, Siberia and the Far East, where uneconomical and slow helicopters are now operating.

                        The AW609 tiltrotor, developed by the English-Italian company AgustaWestland, appeared in 1996 as the Bell XV-15, which was jointly created by Boeing and Bell. After Boeing left the project, Agusta took its place, which merged with Westland and bought its stake from Bell. Now there are flight tests of this car. It is planned that in the near future it will pass certification and appear on the civil transportation market.

                no, well, but it is necessary to carry 6-8 tons, take off from the penny and fly at 500 km / h. Low landing speed (at 50 km / h) will reduce the landing glide path, which also needs to be taken into account, and the second wing also reduces the transverse span on the ground

                        Which is better? V-22 can transfer more paratroopers per unit of time (it can return faster after a new detachment), and most importantly less time is in a dangerous space. Have you forgotten about the evacuation of pilots? To transfer reinforcements, a simple example from life (In Afghanistan), a detachment ambushed V-22 and was able to deliver reinforcements and evacuate 1,5 times faster than a regular helicopter would do. Another USSOCOM (US Special Operations Command) ordered itself CV-22- and they already understand a lot about this. The most howling unit of the Air Force, there is no military conflict where the United States is at least somehow involved without them.
                        Although it’s silly to push a helicopter and a tiltrotor into one’s forehead, sometimes one is better sometimes the other depends on the tasks.

                  C-130 with a wingspan of 40 meters takes off and lands on the deck of an aircraft carrier in the presence of an obstacle in the form of a deck superstructure. The take-off weight of the aircraft with a minimum amount of fuel and engine power 18000 hp is 36 tons (2 kg / hp.).

                  With normal loading in 18 tons and maximum refueling of internal fuel tanks, the take-off weight of the C-130 is 72 tons (4 kg / hp). It is enough to install twice as powerful engines on the aircraft and it will normally take off and land with an 250 meter long GDP.

                  The latest modification of the C-130J (speed 645 km / h, range 5200 km) is more than half the price of the Osprey with a carrying capacity of 2 tons, the flight characteristics of which I do not even want to bring.

                  In the image and likeness of the C-130, it is possible to create a whole line of shortened takeoff and landing turboprop aircraft. In this case, an SUVP with an equal carrying capacity of the Osprey will be much cheaper than the latter by an order of magnitude.

              And if the videoconferencing system had an Osprey analogue, maybe everything would be less tragic

              Those. you guarantee that a much less tenacious Osprey with a carbon fiber fuselage and a wing stuffed with hydraulics would definitely survive under fire from the ground?
              And the fact that the pilot was shot in the air, and not on the ground? Those. it can already be concluded that at that moment even a hypersonic tiltrotor could do little.

              I'm just wondering how you imagine the situation?

                The point is that for rescue operations, maize aircraft are not suitable at all ... The faster the rescue helicopter or tiltrotor flies into place, the better ... The Americans and their allies have long mastered landing from a hovering helicopter or tiltrotor along ropes (like recently Turks in Ijilik), landing right away is not necessary ...

        You won’t surprise anyone with such numbers for a long time. Most of the cars present in the frame are variations on the Fi-156 Storch theme, which was adopted by Germany back in 1937. Its takeoff run was a maximum of 65 meters, and after landing - 22 meters. With a headwind of 40 km / h, the aircraft could hang in the air without loss of control. Using such a wind, you can greatly reduce both takeoff and landing on Fizeler.

          By the way, I forgot something about slotted wings, with the forced creation of a sparse boundary layer, both due to flow around and due to the compressor. They have a chip with a very high bearing capacity, but unfortunately only everything is on the verge of experimentation.
          And in theory, when landing, you can partially take air from the compressor of the gas turbine engine to reduce the speed of stall, so as not to make a separate fence. But R&D must be carried out concrete. Here are some interesting models where slotted wings are used to reduce stall speed at high angles of attack. Just what you need for the UVP aircraft.

    Why should our designers not consider installing a pusher propeller for K-52 helicopters?
    There are two keels on the tail, one between them, and maybe even two pushing screws in a round protective

                      They are not right, I have been tracking high-speed ones for a long time, I assure you, aerodynamics both in Yuriev and Mile - "from teeth", and in the sense too. Now I came to one thing that only a tiltrotor can coordinate the entire AON fleet, and only according to my invention (it’s not in vain that I went to it for more than 25 years) - this is not fanaticism, this is objectivism. the state of things that the cost of a helicopter and an airplane, usually of two halves, and approximately equal: glider / SU. So, in my tiltrotor there is only one indivisible part - the glider, because the classical SU, gearboxes, angular gears and transmissions, on it no, absolutely (!). And the fuel is LPG, the price of a liter of which is within 15 rubles / liter.

    The article unfortunately did not offer anything new. All the same talk about promising patterns, experiments and intentions.

    The phrase "interventions in Iraq and Afghanistan". According to the dictionary:

    Intervention (lat. Interventio - intervention) - military, political, informational or economic intervention of one or several states in the internal affairs of another state, violating its sovereignty.

    Intervention can be military (one of the forms of aggression), diplomatic, informational, economic. All types of intervention are incompatible with the UN Charter and are prohibited by international law.


    In Afghanistan, an operation was conducted with the connivance of the UN Security Council. Unanimous Resolution Resolution No. 1386.

    As for osprey, this idea can be developed in the following direction, instead of installing turboprops, install turbojet engines not in rotary nacelles, but like on a regular plane, use the controlled thrust vector for takeoff, that is, make nozzles rotate 90 degrees.

          Helicopter Prop Converts power to work. What turbojet engines do not have. Therefore, the power of the v-22 engines in the area of ​​4000 book.

          If there is no screw, the turbojet engine power equal to the mass of the V-22 itself is needed, that is, it needs engines for 12 tons of thrust.

          Like the 737 buoy CFM International LEAP)))


          Not the best option. And they will devour the floor of the poor fellow’s tank on take-off, like all VTOL aircraft

    The article forgot to mention Agusta Westland 609.

    AW609 commercial convertoplane is a long-term project of AgustaWestland. It was launched in 1996 year, under the Bachnumx index jointly by Bell Helicopters and AgustaWestland (and initially Boeing also participated in the project) as a kind of reduced (six to nine passengers) civilian version of the convergent plane V-609 Osprey. Due to technical difficulties and practically unsolvable problems with the civil certification of the Bell Helicopters apparatus, it ultimately came to the conclusion that the project was unprofitable, and in 22, it came out of it. After that, the program is fully implemented by AgustaWestland under the designation AW2011.


    To date, only two AW609 prototypes have been built (АС1 and АС2, the first flights in 2003 and 2006), and the testing and fine tuning of the vehicles has been extremely delayed. Finally, the second prototype of the AC2 crashed in Italy on October 30 2015. Certification of the device, which was originally scheduled for 2007 year, is now expected no earlier than 2017-2018, and even the opinion exists that AW609 will never be able to get an American type certificate due to the unattainability of the certification requirements for flight safety on it.


    80 solid orders. The catalog value on 2010 year is 29 million.

    The second flight prototype of the Agusta Westland AW609 convertiplane is a prototype of the AC2 (US registration N609AG). This car crashed 30.10.2015

    The coaxial scheme for light and medium helicopters is more relevant. It seems to me that they undeservedly forgot the American scheme without a tail rotor (with a fan in the tail boom and controlled blinds). Add to the scheme a controlled vector of thrust back and to the side and everything is fine.

    An interesting development on the subject of high-speed helicopters was in the USSR. It was MI-42, designed to replace the MI-24 "flying BMP". The MI-42, among other things, did not have a tail rotor. Its functions were performed by gas-jet rudders.

    The article is good, although not detailed, but the coverage is quite wide. It is a pity that they forgot about the project of the Sarov Bureau. By the way, Kamovtsy rotorcraft engaged in a very long time. And they flew in their metal. The principle is the same as that of the apparatus of the Sikorsky company, although the design was completely different. The device, it seems the Ka-22 was called. It is necessary to google.
    If the designers, the military and the leadership thought like some commentators, we would still be flying on the Wright brothers' apparatus. Tu, Boeing and Airbus are much more expensive! Why, in general, spend money on the development of aviation, the plane did the Wright brothers fly! Well this is a specific cut dough! Well, how much you could drink with that money! Or you can take them offshore, and these wise men spend them on some helicopters! Precisely cut!

    http://www.airwar.ru/enc/ch/ka22.html Тут про Ка-22. 1960 г., однако. По нынешним временам характеристики, конечно, не запредельные. Но принцип тот же что и у перспективных винтокрылов - крылья и несущие винты несут, а тянущие тянут. Главное достижение современных винтокрылов - это лопости несущих винтов, работающие без срыва потока, даже, при обтекании задом наперед. НИОКР в этом направлении фирма Сикорского вела ещё в 80-х годах прошлого века. Об этом в те годы зарубежное военное обозрение писало. Только тогда винт несущий был у них не соосный и, кажется, останавливался в полёте на больших скоростях, работая как Х-образное крыло. Дальше эксперимента не пошло, соосные винты выгоднее. Вот так и создаются принципиально новые образцы техники, в результате десятилетий НИОКРа. А если через год орарь, что результата нету, что это распил, так и будем старые танки новой краской перекрашивать и выдавать за инннновации. Опытный образец "Арматы" поехал, когда ещё такого слова, "инновации" не знали, а новая техника была. А сейчас диковинные слова с забугорья перенимают, пыль с советских разработок стряхивают, бантики привязывают и выдают за принципиально новые разработки.
