Race against the US: will Russia get the fastest attack helicopter in the world?

Good heredity



TASS, citing the press service of Rostec, reported on the testing of a new version of the Mi-28N attack helicopter, equipped with blades with new saber tips. They are designed to increase the speed of the car.

"Russian Helicopters" holding will present at the forum [exhibition "Army-2020", which will be held from 23 to 29 August. - Approx. Auth.) know-how: a blade with a saber tip, which will increase the maximum speed of Russian combat helicopters. At present, the blades of this type are undergoing factory flight tests on the Mi-28N helicopter ",

- said in a statement by Rostec.

Back in 2018, Kirill Sypalo, the head of the Zhukovsky Central Aerohydrodynamic Institute (TsAGI), said that TsAGI and Mil OKB had created a number of technologies that would make it possible to increase the speed of Russian combat helicopters to 400 kilometers per hour: about the same number should be developed by promising American combat helicopterswhich we have already talked about.


The main focus of Russian developers is on the creation of new rotor blades, which, according to the idea, will dramatically increase the speed of existing helicopters. Kirill Sypalo noted that the blades of the new design will make it possible to reduce the negative aerodynamic effects that occur in helicopters of the classical layout.

This is not the first attempt to modernize the Mi-28N, which in turn is a deeply modernized version of the Mi-28A. Earlier, Russia has already adopted the Mi-28UB helicopter, the main difference of which is a double control complex and improved safety indicators. The newest and most advanced version of the Mi-28 today is the Mi-28NM. Among the main differences are the standard nadvulok radar station, the "rounded" front part and the ability to use the latest aviation means of destruction. The arsenal of the Mi-28NM is to include the mysterious Product 305 missile, which is reportedly capable of hitting targets at a distance of 100 kilometers.


Considering how much controversy the Mi-28NM caused (according to one version, due to the high cost that did not suit the Ministry of Defense), it is naive to believe that the army expects to get a new, even more advanced version of the 28th soon. Most likely, the tests carried out now are a kind of investment in the future, in which there may be no place for modern "slow" helicopters.

It is important, however, to note one point. Despite all the advantages of the Mi-28, this is far from a new machine. She performed her very first flight on November 10, 1982. Of course, the electronics and weapons of the Mi-28 will continue to improve, but it is unlikely that a machine will be created on the basis of this helicopter, which, as stated above, will be able to reach speeds of 400 kilometers per hour.

There is an alternative point of view on these kinds of questions. Earlier, Boeing unveiled the appearance of the new super-fast Apache. It is assumed that by using a third pusher rotor located in the tail section, it will be possible to increase the speed and range of the AH-64 by 50 percent, as well as increase its efficiency by 24 percent.


Could the Mi-28 go the same way? On the one hand, the Mi-28 is conceptually close to the AH-64 helicopter. On the other hand, the prospects of the fastest Apache are more than doubtful. Recall that not so long ago, the United States chose two winners to create reconnaissance and attack helicopters for its ground forces in the framework of the FARA competition. Two cars, developed from scratch and not a modification of something already existing, made it to the final. These are Sikorsky Raider-X and Bell 360 Invictus.

Uncertainty itself


The modernization of the Mi-28 is not the first and, presumably, not the last attempt by Russian engineers to work out the concept of a high-speed helicopter. Back in 2015, a demonstrator of a domestic high-speed car, made on the basis of the Mi-24K, took to the skies for the first time.

As noted by the bmpd blog, the prototype was initially created within the framework of the "Promising high-speed helicopter" (PSV) theme: the main element of testing, as in the case of the Mi-28, was to be the development of innovative rotor blades. However, then the specialists were forced to revise the concept, since it did not fit into the technical requirements. It was, in particular, about the impossibility of reaching the required cruising speed, while ensuring the relative efficiency of operating the rotorcraft. Ultimately, research work on the topic of "Promising high-speed helicopter" was stopped in 2014, but the results were decided to be applied for other work in this direction.


It is difficult to say exactly how the Russian high-speed helicopter of the future is now seen. Obviously, the Ka-92 project, the layout of which was presented at HeliRussia 2009, as well as the almost forgotten Mi-X1 and Ka-90, will remain projects. True, in 2018 TsAGI confirmed previously received information about the development of a high-speed attack helicopter in Russia and even, interestingly, spent a few seconds on it in the program TsAGI 100 Years: The Science of Fly. According to the available information, the speed of the car will be approximately 400 kilometers per hour. The helicopter is seen with a coaxial rotor, additional propellers, a two-seater cockpit with crew members side-by-side, and internal weapons bays.


In 2019, Andrey Boginsky, head of the Russian Helicopters holding, shared new information on this matter. According to the data presented at that time, research work on the new attack helicopter has already been completed, the specialists are ready for the next stage. Moreover, the car is conceptually different from what TsAGI showed earlier.

“The priority was given to the machine of the classical scheme, let's call it that, but the decision to start development has not yet been made. At the moment, the version with the classic propeller layout is most consistent with the issued TK, but the Ministry of Defense can make adjustments to it if it deems it necessary, "

- explained Boginsky.

Summing up the available information, it becomes obvious that Russia is betting on the existing versions of the Ka-52 and Mi-28 attack helicopters, including the Mi-28NM and the recently maiden flight Ka-52M. Despite the progress in this area of ​​the United States, Russia is not yet ready to compete with the United States in this area. On the other hand, there are no guarantees that the Raider-X and Bell 360 Invictus will be successful. It's enough to remember history with RAH-66 Comanche, on which great and, as we know, unfulfilled hopes were once pinned. Uncertainty to the situation is added by the rapid development of UAVs, which, by the way, became at one time one of the reasons for the rejection of the development of "Comanche".

          As tests of prototypes show, the very concept of the helicopter does not allow increasing the speed to the existing one by more than 150 km per hour, which is absolutely not essential. Therefore, the speed increment by 50-60 km "playing" only on the tip of the blades is a more realistic option. If we talk about the essence of the title of the article:will Russia get the fastest attack helicopter in the world? then the answer is:"definitely NO". yes

                At high speeds, it is closer to the gyroplane. The carriers are involved only in creating the lift
                Moreover, the higher the linear speed, the lower the rotational speed.
                This solves the problem of speed limiting due to the output of the tips to supersonic

          But the versatility of the machines gives convenience and economy in maintenance, saving time to prepare for a combat situation. Plus an increase in production volumes, and, accordingly, the number of those put into service.

      For example, an old crocodile, the Mi-24, reached a speed of 368,4 km / h. Let it be as lightweight as possible, without weapons, but it was close enough to 400.
      The main problem with high-speed helicopters is the stall on the blades. In this case, the helicopter with the loss of lateral stability falls to the right. This is called deadwood

        Moment, did not the Yankees themselves assert that the future belongs to unmanned helicopters?


        At the turn of the 70-80s, with the advent of ATGM, there was euphoria. "The tanks are lousy, a squadron of helicopters will burn an entire regiment and won't frown." Then the infantry grew its teeth, and the helicopter at a distance of 8 km will live 4 minutes. Jews made rockets for 11 km. The tactic boiled down to "hitting a previously explored target and bringing home gardens."
        In local wars, the attack helicopter had - convoy escort, transport cover during the landing, inspections of trade caravans, cover of the airfield during takeoffs and landings. Pivot points if the infantry is in trouble and does not have its own means. Vitality and armor come first. And the increase in speed would be good for free, but not at the expense.
        But these are "wars". And how it will be in the meat grinder of the fronts - no one really knows.

    the tactics of using helicopters in us and in the west are different, hence the difference in approaches in the means of increasing speed characteristics. even a 30% increase in the cruising speed of existing aircraft by upgrading the carrier system will significantly improve the operational flexibility of helicopters. do not forget that in addition to the relatively small number of mi-28s (about a hundred according to millitary balance 2019), there is a solid available fleet of mi-8s, which have significantly lower speed characteristics. The development of high-speed blades technology on a relatively small machine can further open the way for the modernization of the existing Mi-8 fleet. in addition, teaching the unification of the mi-28 and mi-35 on the carrier system, the possibility of modernizing the latter is laid. even if the modernization of the Mi-35 does not interest our MO, it can interest foreign customers. this is at least a load for the enterprises of the Holding, which are significantly sagging in the face of a decrease in military orders

      And I will give you a task! There are two helicopters: one has a speed of 350 km / h, the other has a speed of 250 km / h, but the first takes 1500 kg of cargo, and the second 3000 kg. Who do you prefer? (comparison of Mi-24 and Mi-8)

        I will continue on this topic. What engines are on these helicopters? Exactly the SAME! (TV3-117VM), and the gearbox? (BP-14) so ​​what's the difference? And everything is simple on the Mi-8, the HB diameter is 20,3 meters, and on the MI-24, 17,3 meters! that's all! If you want to lose speed in the load and vice versa! I forgot to clarify that at an NV speed of 95% both on the Mi-8 and on the Mi-24 the NV speed is 192 rpm.

          I can't help but mention your attention to detail and plus. I agree with you that such parameters diameter, rpm and filling factor HB have one of the defining influences on the entire range of flight characteristics and the carrying capacity of the helicopter. By the way, about the details: you "shortened" the NV of the eights by one meter, and the engines TV3-117V (mi-24), TV3-117VM (mi-8mt) and TV3-117VMA (mi-28n) are probably structurally very close, however, have differences in distribution according to operating modes (in the field of takeoff and emergency).
          In principle, it is possible, while maintaining the above parameters, to achieve an improvement in its characteristics and the performance of the helicopter as a whole. As an illustration, I can cite the use of the new NV on the Mi-171a2 and the related increase in cruising speed by 20..30 km / h with a takeoff weight of 11100 kg. At the same time, at the first stage of testing the mi-171a2, the old tv3-117vm was used. (See the article Results of the first stage of flight tests of the mi-171a2 helicopter flying laboratory at the cyberleninka).
          In my first comment, I meant that the application of new advances in the aerodynamics of HB blades can improve the speed characteristics of the helicopter without compromising other characteristics.

      I read in Chechnya used the tactics of 2 Mi-24 + 2 Su-25. The air controller gives the coordinates by which the helicopters enter first (as more maneuverable ones), working out with tracers, if the gunner confirms, the planes are working. For this, probably, and speed, so that the point is not too late to leave.

    On the eve of the war, the Il-2 with the gunner was forced to rework into a single-seat one, "in order to increase the maximum speed and flight altitude." Everyone knows how it ended.
    It would be better to create a design bureau for the development of piston engines for UAVs and cars and a design bureau for the development of advanced on-board systems and guided missiles for destroying mobile ground targets at night and in poor visibility conditions. But, obviously, these are unsolvable problems.

    If we compare the fighters of the beginning of WWII with the later ones, then the speed just increased, from 400 km / h to 600 km / h, and the aerodynamics changed a lot ... And the helicopters like Apache and Mi28, just fall short of such aerodynamics. And the chassis must be removed and the weapon must be hidden and the contours must be refined.

    A combat helicopter will have to sacrifice a lot for a penny increase in speed. Then it's easier to uncover the "verticals" and revise them in a composite, although judging by the Amerovskoy 35 Besshkam, it still turned out to be some kind of crap. But for airborne transport purposes, it would be nice to concoct something like a domestic tiltrotor ... Osprey is very much in demand among the Stars and Stripes.

    I do not really understand why you should be so caught up in speed
    It seems to me that a range of up to 250-270 km / h is enough for a HELICOPTER, which has been achieved a long time ago.
    Probably, it is possible to build a helicopter faster than today, then in my opinion it is better, instead of one such record machine, to make a regiment of simply more advanced machines according to the old scheme.
    And if you need a car faster, in my opinion it is already worth switching to cars that are more adapted to speed, for example, a tiltrotor scheme.

    The speed of the helicopter is limited by the propeller blades. To increase the speed, you need to fold the blades in flight and fly in airplane mode, then it will be possible to significantly increase the speed.
