Has Russia made a breakthrough in the creation of high-speed helicopters?

92
In June, the prototype of the Russian high-speed helicopter, known by the abbreviation PSV, as promised, will take off for the first time and accelerate to the speed of 450 km / h. Does this mean that we are on the verge of a breakthrough in the practical creation of really high-speed helicopters?
On Thursday, 19 May, the HeliRussia 2016 international helicopter exhibition opens in Moscow. At the pre-press conference, it was announced that in June our prospective helicopter would reach a record speed.


Rotary-wing cars, flying at such speeds, we really need. For the first time they were started talking about them at the HeliRussia 2009 exhibition. Then they solemnly announced that they were starting work on a project of a domestic high-speed helicopter, which was the main and very joyful sensation of the exhibition that took place seven years ago.

It is worth recalling that in the US and Western Europe today are actively experiencing high-speed rotary-wing machines. Not everything works out for them, but their helicopters fly, stably show speeds around 400 km / h, are demonstrated at many air shows. And we should never have been left behind.

On HeliRussia 2009 showed a number of options for the possible layout of promising high-speed machines. As a working concept, we chose the project of the Ka-92 helicopter. According to the stated characteristics, the car had to carry 30 passengers for one and a half thousand kilometers at a speed of 450 km / h, take off and land on any unequipped but level platform. Such a rotorcraft, if implemented, could have revolutionized the transportation of hard-to-reach territories in Russia.

It was assumed that the main customers of the high-speed helicopter and the financiers of its creation will be oil and gas companies, rapidly moving to the North and even to the Arctic. You can’t think of a better machine for providing shift shifts and eliminating possible emergencies where no aircraft will land, and you can’t think of a regular helicopter.

According to the then head of the helicopter industry, Andrei Shibitov, the project should have taken no more than eight years to complete. According to the developers, with proper funding, the Ka-92 could be lifted into the air and even prepared for mass production in five years, that is, in 2014-2015.

Recall from the day of the layout of the perspective high-speed helicopter passed seven years. Where is the car?

In the metal she never appeared. But without unnecessary advertising noise, they built a flying laboratory called PSV, a promising high-speed helicopter. From the budget for PSV spent a lot of money. For the first time this miracle of technology was shown at last year's MAKS-2015 air show. It is PSV that should reach record speed in 450 km / h in June. According to the scheme - this is a classic helicopter with the main and compensating screws.

As it turns out now, managers and financiers ultimately identified the look. There was one criterion. High-speed car should not be much more expensive than the classic. And her form should be classic. What the helicopter builders believe is basically impossible.

First of all. If we talk about the cost, then the jets initially were several times more expensive than the piston, but today the whole world flies mainly on expensive jet engines, and not antediluvian pistons. And the high-speed helicopter will not be able to compete in price with the now familiar machines, it will definitely be much more expensive.

Secondly. For some reason, efficient managers ignored the opinion of aerodynamics - a high-speed helicopter cannot be built according to the classical scheme with supporting and compensating screws, like PSV. The moment will inevitably come when the rotary-wing collapse cannot be compensated by any tail rotor. His speed will be obviously limited.

High-speed performance provides only coaxial circuit. In this case, the rotor screws should no longer be long and flexible, but short, rigid and rapidly rotating. These screws provide sufficient lifting force. But to give the necessary speed you need a pushing screw or even a jet engine. In this case, the speed in 450, 500 km / h and even higher will become usual, economical and safe. According to this scheme, and was supposed to build Ka-92.

The termination of financing of the project announced many years ago was habitually explained by a crisis, a reduction in the revenues of the oil and gas complex, and a decrease in its ambitions. But we must think about tomorrow and about state interests in all their complex.

We have almost collapsed regional flights. Many airfields in the Russian hinterland are a terrible sight. Hundreds of billions, if not trillions of rubles are probably needed for their restoration. Where to get them? But high-speed helicopters do not need any concrete runways. Need only a flat platform. And if we take into account the costs of restoring the regional aerodrome infrastructure throughout the country, compared to the costs of the speedy creation of a high-speed helicopter - even effective managers must understand what is more profitable for the country from any point of view.

Alas, now the question is almost always solved not from the point of view of the general state benefit, but taking into account the interests of individual holdings or corporations.

Meanwhile, in addition to the civilian aspect of high-speed helicopters, there is also a very important military component. At previous HeliRussia salons, concepts of percussion combat vehicles took off openly, taking off in helicopters, then folding their blades and turning into jet attack aircraft, developing speeds up to 900 km / h. Moreover, these machines are already in the project adapted to work in the Arctic. Fantasy! But it could be implemented.

Time to create a domestic high-speed helicopters missed, but still not lost. And what path the Russian helicopter industry will take - we will see soon.

If the mysterious while PSV really takes off in June and accelerates to 450 km / h, it will be nice. The billions spent on it can be justified. In addition, it is argued that the helicopter propeller, created from new structural materials and a new configuration, can be tested at the flying laboratory. And that's good too.

That's just for the really promising high-speed helicopters, neither PSV nor its flexible screws, even the newest generation, will have anything to do with - just by the laws of aerodynamics. So the question of creating a domestic high-speed rotary-winged helicopters remains open.

"... even effective managers must understand what is more profitable for the country from any point of view ..." All these " managers "and" financiers "NEVER (remember this word) will think AT THE STATE level, i.e. - STRATEGIC. All their thoughts are to fill their pocket as tightly as possible (while they are at the feeder). And at the state level it is the leaders of the state who should think (how many more people like Putin do we need ???) or the leaders of the state level. Enough already to drag the country to corners and uluses and "grab" everything and everyone!

      - I think so.
      Only the MBA knowledge system is very extensive. And it’s impossible to get out of there by a universal - life is not enough.

      The second point is that there are no conditions for the Russian "Lomonosovs" now - MBA training starts with about 200 mowers - and this is far from "full stuffing."

      Question - guess three times, who will overcome this barrier?
      That's right - the majors, who have never been accustomed to strain, but have almost from the diapers of a lamborghini in the garage.

      And to whom will the "daddy" give the key post of the enterprise? Also right - to your certified offspring.

      And the enterprise in Russia, if necessary (but even if it is a hundred times unprofitable) will work. And to cut the budget for a thousand bucks for a simple nut, more like a "daddy" handles with the government or with YOURSELF.

      Well, who will object?

      Therefore, we do not have either small or medium-sized businesses. And there are oligarchs who have the whole country.
      Even foreign enterprises with their technologies pass to the administrative resource and close.

      That’s where inefficiency comes from and you don’t have to blame it on MBA.

        Perhaps you are right - MBA has nothing to do with it, it is about people - their moral, business and professional qualities. As "effective" people like to say: there must be the right motivation. And the motivation of Russian TOPs is the same - to row loot and sneeze at everyone around. Actually above, on the second link, the motivation of the TOPs is very well described, which the author called briefly and succinctly: "ratism".

        - We want them to be violated. You'd better remember: you are not dealing with a group of Boy Scouts, and the time for beautiful gestures is over. Power is behind us, and we know it. Your friends are goodies, and we know the true state of affairs, and you should be smarter. It is extremely difficult to control innocent people. The only power the government has is the power that can break the criminal element. Well, if there are not enough criminals, you need to create them. So many laws are adopted that it is impossible for a person to exist without breaking them. Who needs a nation full of law-abiding citizens? What is the use of it? But issue laws that can neither be observed, nor enforced, nor interpreted objectively, and you will get a nation of violators, which means you can make money on crimes. "

    And what? 220-260 km / h on Mi-8, -26 are no longer able to help in the development of the Arctic Russia and dough menager? Come on 450! And no km / h less?
    The military does not require, apparently, +200 km / h for MANPADS not fundamentally.
    I remember we flew to Volgograd from Krasnoyarsk with my cousin on IL-18. And I would like to Tu-154. Newer, prettier, FASTER at 200 km / h. While we were counting, we wouldn’t save hours! And with the registration, boarding and baggage claim there is no difference - there are fewer passengers. Existing airfields and roads need to be maintained and restored, and menager’s asses and on classic turntables will fly for less money, they will suffer an extra ten minutes.

        Helicopters have a natural limitation of flight speed - a stall in the retreating rotor blade.
        For helicopters with a take-off weight of up to 10 tons, a breakdown occurs at a flight speed of approximately 100 m / s (360 km / h). To achieve this speed, it is required to provide a thrust-weight ratio of 1 hp. engine power per 2 kg helicopter weight (5000 hp for 10 tons of take-off weight).
        This level of thrust-to-weight ratio also ensures vertical hovering of a helicopter in case of failure of one of the two engines.

        To achieve a speed of 140 m / s (500 km / h), one hp is required for each kg of take-off weight. power, as well as double the number of rotors, since their bearing capacity will drop by 50 percent due to flow stall. As a result, the helicopter’s flight range, its cost and the cost of transportation (which is already off scale) will fall by half.

        Therefore, it is easier to set up field airfields for helicopters of short take-off and landing than to throw money away, developing vehicles with a non-core mover.

          But if you build the process according to new algorithms, then you can increase the thrust-weight ratio and reduce fuel consumption, which means increasing the useful duration and range, as well as increasing the speed to the plane. It’s just that all processes must be solved by changing the flux density on the blades.

        But - the Americans have already resolved this issue - Bell V-22 Osprey.

        Gizmo is also wildly expensive and stable only at the expense of sophisticated electronics with a cloud of gyroscopes, acceleration sensors and processors.


        And the question is - what is more promising: a tiltrotor or a coaxial helicopter?

        I saw somewhere a drawn idea of ​​a hybrid of an airplane and a helicopter - take off like a helicopter, then, with a set of speed, when the lift of the wings began to act, the blades stopped, folded into a "stack" and lowered into the body.

            It is comforting that there are thinking people who understand the essence of the problem. The only question is that no one knows the solution to this problem, which is solved by the fact that the speed at the tips of the blades can be increased by an order of magnitude, which will increase the "reference" air flow, with all the positive effects

              tell me, is the essence of the problem not that the increased flow velocity (first at the tips) of the blades becomes "not lifting" for the propeller to tilt it down? The question is: why increase the flow rate when you need to change its vector? Or will your "ionization" help the blades slow down and turn this flow? (and the blade will not break?)

                It seems to me that it is necessary to separate the state of the air flow moving along the blade and the total energy state of the air of the very environment in which the entire flying object and its blades are located. Sparking with all its parameters at the tips is a consequence of the EMF in the propeller blade and it is absolutely obvious that this is a consequence of the ionization of the blade surface by air. I think you will not argue with this, but I will not yet describe all the processes that are formed on different parts of the blades. So it turns out that in order to increase, so to speak, the power of the flow driven by the blades, and accordingly this flow creates a reference interaction with the environment, which creates all the vectors of reactive action, so that the lifting force is higher, and therefore the payload is higher and that's it other necessary parameters of effective flight, then it is necessary to increase the rotational speed of the rotor of the carrier blade. This will make it possible to drastically reduce the radius of the blades (their length) and at the same time the volume and speed of the air flow will create all flight conditions. Therefore, the task is that it is necessary to reduce or balance the EMF force in the centrifugal rotation of the tips and the blades themselves, so that there is no complex of destructive processes in the blades. All that has been said is only a part of the overall process, because the dynamic processes of the air flow itself cause transformations in its structure, which also causes the energetic aspects of such transformations. Therefore, we are talking about such new devices that harmonize the overall processes both in the medium and in the dynamic flow of the outflow and in the very structure of the blade material. We combine the kinetic energy of the flow and its potential transformations. The task is that "nothing" interferes with anything and we can create only positive extrema at each stage of the structure of the device and environment. To unite and link all this, it is necessary to work on a new methodology for analyzing all cumulative processes.

                  I'm afraid you still do not fully understand: the problem (at least at this stage) is not in the strength of the blade, but in its inoperability at high aggregate speed (translational motion and rotation of the screw). Reducing the diameter of the propeller with increasing rotational speed is also not a good idea, since the aircraft itself is located under the propeller and not above it - accordingly, part of the propeller’s work is spent on pressing the aircraft to the ground, instead of lifting it. Therefore, it is the ends of the blades that work most effectively

                    I note that I am not talking about strength at all. With the modern principle of operation of the blades to create lifting force and the force that creates the possibility of longitudinal flight, there is a whole range of limit levels of interaction of magnetic fluxes and their potential. From this, the effect is observed that the application of power on the motor shaft does not allow to increase the rotational speed of the rotor blades. The desire to harden the blades themselves will lead to an increase in vibration. Vibration, in turn, is the process of distribution of wave effects as the dimensions of magnetic fluxes in the algorithm for their transformation. I think that you hardly understood the last phrase because in the analysis of the process we use different methods. But I think the essence is clear anyway. Therefore, I note only that reducing the length of the blades without reducing the productivity of the pumped air and the direction of the air flow with a positive result on the rotor shaft allows generally instantly switch to the electrical supply of the drives, rather than using any fuels. A drastic reduction in the scale and weight of such propulsors combined with the function of creating a positive moment of rotation on the shaft will allow not only the propulsion engines themselves to be placed in any part of the housing. that is, we get incredible energy saturation, which directly affects the provision of the flight itself on any vector, as well as the absolute safety provided by the backup propulsion engines.
                    And you are absolutely right that the ends of the blades work as the most efficient stage of the blade’s work, which can be implemented to convert the potential energy of the air, which with a modern design creates a lot of problems, and in our case a lot of positive effects

                      Unscrew existing screws faster - no sense.
                      make them stiffer and smaller - well, you can increase the pitch of the propeller, you can use a coaxial scheme, you can even increase the area of ​​the tips, like on LINKS, or bend them down, like airplane wings bent upward - all the same, this will give little in terms of speed.

                        I do not understand why you are cunning saying that the screws can be untwisted to higher speeds. It's hard for me to talk about your competence in these matters. Let me remind you of the destructive ability of water through its cavitation effects to destroy the surface of the outflow. In air, everything happens in the same way, but with an impulse to rupture the surface of the outflow by an explosive character. Therefore, it’s difficult for me to explain sometimes that at high speeds of rotation of either a rotor blade or just a solid disk, a complex of processes is observed leading to the destruction of the rotor. many, if not all, forget or simply are not able to see that all energy processes in the medium are determined by the medium itself and its properties. And then I terribly do not like it when someone imagines himself to be such a prophet who knows and understands the essence of physical processes. Good luck to you!

        Any military doctor will tell you that for a fighter who was injured of moderate or severe severity, it is no longer fundamentally important how long you will deliver him to the hospital, with a high degree of probability, by this moment he will already be dead. In this regard, it is much more efficient and cheaper to equip a sort of resuscitation based on the Mi-8, so that medical assistance to the wounded soldier begins to be provided immediately after loading on board. Then the chances of survival increase dramatically!

    I am very critical of rotorcraft and convertiplane due to their very complex transmission, as well as the tendency to vibration. How many projects did not reach production? The same Ka-22, the English Rotodine, the American Chayn. The current Osprey is in itself an extremely dubious and unreliable machine with a weak payload. Maybe they themselves are generally a dead end branch?
    If it is possible to justify somehow vertical landing aircraft, although the cargo there also essentially consists of fuel, nevertheless, relatively reliable operation can be achieved from them.
    And there are also the so-called multicopter, but then again, either make small devices, and even have an individual engine for each screw, which again complicates the device excessively.

      There is no need to appeal to those who do not understand anything in the substantive solution of issues. Behind the simplicity of the device (relative) execution is the complexity of the processes that must coordinate the ongoing processes in the material of the blades and in the environment in which they move. Therefore, no one sees and is not able to simulate such new devices. But! it is already unequivocally possible to justify the totality of all sequential processes and the calculation method of such a device. Therefore, it is a matter of time before someone wishes to invest in new breakthrough technologies and the device itself.

          Dead end branch. I will quote the gosh100 blogger. wassat

          Even for its stratospheric price tag, the V-22 goes into battle unarmed. As a result of decisions made by the Marine Corps in the past decade, the aircraft was left without the powerful weapons needed to suppress enemies on the ground before landing. And if there are problems with the engines in hover mode, due to enemy fire or malfunctions, it will simply collapse, because it does not have the emergency landing capability, which saved many lives in Vietnam. In 2002, the Marine Corps abandoned the autorotation emergency landing capability of helicopters. A top Pentagon consultant in a confidential 2003 report called this decision "shameless" for a military vessel.

          So, the screws will be relatively small, which means low efficiency in helicopter mode.
          That is, they will require a lot of power, and give little traction.

          That is, it turns out right away that this will be guaranteed to be a bad aircraft — its propellers are too large for horizontal flight and a poor helicopter — they are too small to hang.
          What do you want? The universal is always worse than the specialized.

          Further: such an apparatus automatically requires a bunch of all kinds of mechanisms unnecessary for ordinary planes / helicopters, complex (and many times redundant!) Hydraulics: you need to turn the nacelles. And you also need to fold the wings and screws so that such cuttlefish would fit on the ships. And you also need to synchronize the screws with a long shaft.
          All this machinery is extra weight and this despite the fact that we already do not "pull" screws!

          So you have to save a lot on something to make the design easier

          Well, for starters, let's make the case out of composites. And what’s not bad - thanks to this, they kept in 1800 kg of everything, on such a colossus!
          True, this carbon fiberglass box is shot from an automatic machine and stands like Abramovich’s yacht. On the armor and we can’t talk.
          Well, how do you like? Wunderwaffles - they are.

          You will also have to refuse extra windows / windows, there is nothing to weaken the design.

          - Yes, yes, still have to abandon the large-caliber machine gun, he also weighs, you know, spoils.
          - you cannot put machine guns in the side hatches - you can shoot the engines yourself.
          - if you want - we put in the ass on the ramp an infantry farthing caliber 7.62 and that's enough for you.
          Well, yes, it will be inconvenient to land through the ramp, the dust will blow into the cabin - but is this better than nothing?

          Customers in the person of the military certainly do not get tired of being indignant and demanding to put normal weapons on Osprey. Developers are not tired of offering different options. One of the latter is to attach a turret controlled by a monitor with a rapid-fire machine gun of caliber 7.62 (IDWS) to the abdomen, but it turned out that this thing takes up a lot of space in the cargo and passenger compartment to the detriment of the landing party, it wedges when firing, and its screws limit the fire sector, and the arrow is sick when he tries to aim on the monitor. As a result, this system is not widespread.

          In addition to adequate weapons, the V-22 developers had to abandon even an adequate life support system.
          The problem is that in winter or at high altitude it is very cold. And there is low air pressure and little oxygen.
          Therefore, normal aircraft designed for high-altitude flights always have a sealed cabin, and therefore, for example, our transport Mi-8 has a huge stove:
          On the high-tech revolutionary V-22, the cabin is not tight (they say rotary mechanisms do not allow sealing!), And the heater is so small and weak that it only provides -10 degrees Celsius when flying at an altitude of 6 km, even when operating at full power. Those. there is a natural freezer!

          The crew and passengers must fly in oxygen masks and Arctic clothing - like the pilots of the 30s in old Soviet films about the heroic chkalovyh. Suffering for hours from the cold and altitude sickness. (see the funny report of the Air Force Colonel from medicine on the problems of high-altitude flights on Osprey)

          Otherwise, the advertised characteristics of the speed and range on the V-22 cannot be achieved, because air resistance interferes below.
          More or less normal conditions for people in the cockpit are provided only at altitudes below 3 km, therefore, it usually does not fly higher actually. Operated like a regular helicopter, within reach of MANPADS.

          What else is not in it? Adequate anti-icing system (constantly with this problem), weather radar, ejected seats for the crew.

          By the way, the safety / accident rate of this bird came out very badly.

          1) He cannot accidentally take autorotations in the municipality (the screws are too small), which sometimes saves the lives of helicopter pilots.
          An emergency landing on an airplane is also a big question. In fact, he has no proven methods to save the crew in an accident.

          2) The V-22 was extremely susceptible to a very unpleasant aerodynamic phenomenon - a "vortex ring". This is when a helicopter propeller creates a toroidal vortex (some smokers know how to make a similar thing from smoke)
        3. kugelblitz
          kugelblitz 21 May 2016 20: 07
          +2
          And if the helicopter is descending, such a vortex can form around the propeller. In this case, the propeller thrust drops sharply and the helicopter "falls through". This is unpleasant, but usually not disastrous for a conventional helicopter. This condition does not develop very quickly and the pilot can usually "catch" dense air and regain thrust.

          In the case of the V-22, a catastrophe is guaranteed - because it rests on two very spaced screws, and when one screw gets into the vortex ring, Osprey immediately falls to one side and falls down with a stone. Thus, 2 or 3 aircraft have already been lost!

          To avoid such accidents, I had to introduce a bunch of restrictions on operation. For example, V-22 pilots minimize helicopter mode, for this they fly up to the site in an airplane at speed and are converted right in front of it for landing. But this is only possible if there is a corresponding open and even space. In the forest, mountains, the city this trick will fail. In addition, they are not allowed to fly closer to each other closer than 75 meters, they are afraid of strong winds and even ascending air currents!

          3) The complexity of the design also does not contribute to flight safety, as well as resistance to combat damage.

          In total, 7 pieces have been lost today, which, with their small number and greenhouse use, is a lot.

          An interesting fact is that the V-22 convertiplanes are certified for use in the presidential air fleet, but not for the President and members of his family. For journalists, there are all kinds of bureaucrats, he is considered quite safe, but not for the President of the United States, nenen, David Blaine! How democratic and symbolic it is.

          In my opinion there are already too many stocks, but that's not all!

          A feature of this tiltrotor is a very powerful, concentrated exhaust, which can raise huge clouds of dust during landing. This dust clogs the engines, dramatically reducing their life, and reduces visibility for pilots and paratroopers.
          Particularly exciting should be landing in such conditions when fired from the ground, with the ramp open at the rear (we have a machine gun there, remember?). And we don’t forget that there are critically not enough windows to monitor the situation on the ground, so in fact, landing paratroopers cannot detect and fend off threats.

            you forgot to mention something - osprey is actively used in difficult conditions, including on aircraft carriers. This indicates its fairly high reliability.
            This was appreciated not only by the Americans, but also by the Japanese, who purchase them for the fleet.
            And all these tweaks about certification are just a transfusion of water, because a lot of things affect such things. Do not forget about politics, lobbyists and so on.

          Also, problems arise during takeoffs / landings on ships, when the jet blows off other aircraft and people from the deck. And also a hot exhaust damages deck coverings (you have to drag special mats for protection)

          So, in the end, this unit turned out to have many serious incorrigible flaws inherent in this type of design.
          But there must be some advantages? For what did he do it?

          You can often read that the V-22 allegedly carries many times more people and many times farther than, for example, the CH-46 helicopter, which it is designed to replace. But this is just a theory; in practice, such characteristics are not achieved. Actually, only 20 paratroopers are fully armed in Osprey (46 in Ch-25), and the radius of the CH-46 is the same, if not more.
          The combat radius of the Osprey with 24 paratroopers indicated on the website of the United States Department of Defense is only 430-450 km.

          What else, more speed? Wow, Osprey can fly faster than helicopters - 500 km / h versus 300. Only in a landing operation this will not help - he still needs to fly along with escorting helicopters, which are normally armed and armored to clear the clearing. The only where this advantage can really work is when transporting the wounded.

          It was especially interesting to see how, thanks to the V-22, the dreams of the Marine Corps came true to land with heavy weapons in the depths of the enemy’s territory, bypassing the coastal defense.

          Specially for transportation to Osprey, such a Growler jeep-buggy in two versions was adapted to fit the dimensions of its cargo compartment - reconnaissance and towing. It tows a 120-mm mortar and a cart with ammunition.

      Corn farmers have been around for a long time, but for some reason it’s more profitable for local airlines to drive any ancient stuff. For example, for local lines just right.



      Or for the very small ones, they could help bring it to mind.

        Well, of course, but the Il-114 was created under the Soviets.
        And when will it be its own development, Russian?

    High-speed performance provides only coaxial circuit. In this case, the rotor screws should no longer be long and flexible, but short, rigid and rapidly rotating. These screws provide sufficient lifting force. But to give the necessary speed you need a pushing screw or even a jet engine. In this case, the speed in 450, 500 km / h and even higher will become usual, economical and safe. According to this scheme, and was supposed to build Ka-92.


    So they went back to AUTO FAT. It remains after take-off to fix the rotor in a position perpendicular to the flight, and we already get the plane, with all the subsequent gingerbread cookies.

      Really! The Americans have already designed a high-speed gyroplane with a rotor moderator to avoid stall flow at high speeds. Estimated speed up to 900 !!! km \ h ...
      When considering this topic for a high-speed helicopter, the question arises, really, why do we need high-speed rotation of the main rotor at high speeds? Here more likely you need the principle of a gyroplane to keep the aircraft in the air at high speed. And for this, a high rotor speed is not needed ... A rotating rotor both from the incoming flow and with mechanical traction, according to anyone, will calmly keep the device in the air. If the flight speed decreases, increase the rotor speed to switch to helicopter mode. Really our designers did not calculate this question?
      So the picture develops, takeoff and landing in helicopter mode, speed gain and transition to autorotating mode with a slowdown of the rotor with increasing flight speed ...
      I am not an expert of course, but I think that this option is quite possible!

        The problem is that the rotational speed of the propellers is always "tied" to the forward speed of both helicopters and ships. If the rotor speed is reduced at a steady speed, then it instantly becomes a brake, if you remove the thrust from it (gyroplane), then with an increase in the speed from the pushing rotor, the incoming flow will tend to unscrew it (the rotor) and it will also slow down if you increase the rotational speed of the carrier, respectively, from the translational one from the pushing one, but reduce the step, then the propeller ceases to create lift, and this, after all, is not a wing and we do not have an airplane

    It’s pointless throwing money away. There’s no difference in the 100-150 km of money spent. For civilian helicopter construction, especially. It is clear when in aircraft building there was a transition from screws to whistles. An increase in speed of 300-400 km / h.

                Osprey, in addition to the vertical exhaust of jet engines, adds a powerful air flow from the propellers with a load exceeding any reasonable limits - 100 kg of weight per square meter of the swept surface (for example, for Mi-8 the screw load is 30 kg / sq.m).

    And why a high-speed helicopter, you can think about using a screen effect. The speed is the same, the operating time is available, the cost of transporting goods is much less than aircraft, not to mention helicopter. The infrastructure is minimal, by the way. And it really will be a technological breakthrough, and not "catch-up", copying other people's ideas and openly cutting public money (mine, that is).

    Now almost always the issue is resolved not from the point of view of the general state benefit, but taking into account the interests of individual holdings or corporations


    The notorious Manturov-Pagosyan tandem, during their "effective management", actually ruined the medium-haul aircraft industry. And this is with a huge demand for these machines, not only in our country, but also in the near abroad.

    As for the holdings, for example, Gazprom is apparently more interested in supporting the "barking Moska" - "Echo of Moscow" and others, than investing in the projects they themselves need.

    Question: Is it time for corporations and holdings to ask
    for the "effective management" of the national property, which they inherited for management and plunder.

    The article is informative.
    I honestly do not believe that it comes to the mass production of such machines. The prototype can and will be made and will go to the test, and then who knows ...
    Judging by the desktop model, it’s generally some kind. In a word, as in the song: “Wait for your mother, wait ... ..your mother!” Now transport helicopters fly at a speed of about 250-280 km / h. Is it worth it to “tear” due to some 120-150 km / h. Why carry 1500 passengers or 30 tons of cargo at a speed of 1,5 km / h to 450 km? The better such a tiltrotor helicopter? For Americans, the Osprey tiltrotor successfully combines the qualities of a helicopter and an airplane. With a maximum speed of 463 km / h, a practical ceiling of 10300 m, the machine can transport 24 people without refueling to a distance of 722 km, and with refueling to 3892 km. Do we have something like that? Alas, only the Mi-26 helicopter capable of transporting 82 passengers or cargo of several tons to a distance of about 400 km at a speed of about 250 km / h.
    In my opinion, this high-speed helicopter is not needed, just as the Ka-60 and Ka-62 are not needed. There are no modern machines with economical piston engines, unpretentious in operation, suitable for use with unpaved runways, like the An-2, Mi-1, Yak-12. Robinson, Bell, Cessna planes fly over my house today, and where are ours? Small aircraft in general have collapsed, the regional is breathing at last. In fact, if you follow the rule that “they first saw the birch and then cut it”, you need to restore or create a ground-based infrastructure and decide: who, how much, where and why to carry. Then it will become clear what is needed for this. They are cracking about the production of IL-114, although the plan is more promising, which should be produced both in the passenger and in the cargo version, similar to the An-26. You’ll start to understand, there’s nothing for that either.

      Aircraft for small and medium aviation, brought to the stage of design documentation and half to prototypes, in the early ~ mid-90s had several in almost all specialized design bureaus, excluding Sukhoi. It is all the more strange that he was the one who was entrusted with the ONLY PASSENGER aircraft project in the post-Soviet period. Apparently, the problem is the same as in the 50s - undercover games and pulling the "blanket" like: "We are the best, the rest do not understand anything in aircraft construction." Raise projects Mig, "Beriev", "Ilyushin" - there are 2-3 cars that can now be put into series, simply by reworking the cockpit for modern equipment. Moreover, you can find EVERYTHING - from medium-haul to agricultural aviation!

    the author, it seems to me, does not take into account the nuance of the speed limit of rotorcraft:
    the speed of the end of the blade when it goes in opposition to the movement of the machine.
    if the helicopter accelerates to 500 km / h and above (!), then the edge of the blade will develop a speed close to the Mach number, and maybe even higher. this entails quite a few negative nuances up to the destruction of the rotor.
    Therefore, it is worth careful to approach the prospects of increasing speed.

      Apparently the question is not in caution, but for starters, in understanding the essence of the processes taking place in the entire process. Even elementary if we consider the generalized process of rotation of the blades, then there is a complete analogy with a unipolar motor. This means the greater the speed of rotation of the blades, the higher the magnetic forces of interaction between the tips and magnetic flux directed towards the axis of rotation through the medium and then through the machine body. You can be sure that this problem is absolutely obvious. Therefore, an increase in speed is possible and dramatically, but only through the possibility of depolarization of the EMF vector in the blades. Moreover, the flight itself is influenced by the forces of gravity and the precession axes arising on the vector of this gravity and that precession axis that occurs on the axis of rotation of the screw. How to harmonize processes and how to do everything wisely, you can learn only if you change the theory of the wing and go to the level of analysis of magnetic force processes, and not some abstract lifting forces, etc.
