The "Kamov" announced a way to disperse the helicopter to 600 km / h

Russia has found a way to increase the speed of a combat helicopter to 600 km / h. It is reported TASS with reference to the management of JSC Kamov.

The general designer of Kamov JSC Sergey Mikheev claims that his company managed to find a solution by which it is possible to increase the speed of a combat helicopter to 600 km / h. Mikheev told reporters as part of the International Aviation and Space Salon MAKS-2019.

The general designer of the design bureau notes that at the moment "We lag behind the demands that exist." The designer mentioned Boeing, which, together with Sikorsky Corporation, is creating a promising car with a speed of 480-550 km / h. According to Sergei Mikheev, Russian programs do not yet have such indicators. However, he claims that a solution was found at Kamov.

I managed to find a solution, I patented it that a combat helicopter can fly at a speed of more than 600 km / h.

- quotes his words "Interfax".

The main promising Russian helicopter is not developed by Kamova Design Bureau

At present, in Russia, the development of a promising high-speed helicopter is being carried out by Milia Design Bureau. The Kamova design bureau, known for its active use of coaxial circuits in helicopter engines, has also developed its own version of a promising machine, but the Ministry of Defense is the main project of a competing bureau.

The draft design of “Kamov” was a “syncopter” with two main and one thrust propeller. Its estimated speed was to reach 420 km / h. The design bureau is currently developing a new generation Lamprey marine helicopter.

Russian perspective helicopter on the way

A promising helicopter, which is currently being developed in the interests of the Russian Aerospace Forces, should go into production with 2022 of the year. About this when he was commander in chief of the Aerospace Forces of the Russian Federation, Viktor Bondarev reported. Initially, it was assumed that a civilian version of the machine would be developed, but it turned out to be too expensive for commercial operation, so all the developments were transferred to the military.

At the moment, several countries are developing promising high-speed helicopters at once, since the maximum speed of modern rotary-wing aircraft usually does not exceed 300-350 km / h. At the moment, there is an extremely small number of cars that can cross the 400 km / h bar: these are S-97 Raider in the USA and Eurocopter X3 in Europe.

So there is nothing new in aerodynamics - the "licked" shape of the body, materials that can work at high temperatures and increased loads on the fuselage, engine, or engines, all of whose power gives the maximum possible speed with its own minimum weight! ";

Can't you come up with a more impressive name?

[Stoler]

This is how much jam this engine will consume? Economy will not tear?

[Svetlana]

The main limitation on the speed of a helicopter is not the shape of the hull (licked not licked) but the propulsion. That is, the most licked form, with the strongest motor and heat-resistant materials, with modern forms of the screw, will not bring anything cardinal.

The helicopter rotor group already operates under heavy loads, and has a limited resource. Recall that the helicopter is military, so there will be times when, willy-nilly, the pilots will have to cut off the supercritical flight modes. The increase in speed will add loads as if not an order of magnitude. I am afraid that a new scheme of a non-existent-pushing group will need new materials that can withstand the life of the operation, which would be economically justified.

No, here the problem is completely different
Namely, the tip of the rotor blades at high speeds go to supersonic. With all the consequences up to their destruction

And this problem is not completely solved by aerodynamics. Because gyroplanes, because tiltroplanes, because the record "Lynx" is so expensive that it did not go into the series.

[ProkletyiPirat]

Quote: Spade

Namely, the tip of the rotor blades at high speeds go to supersonic.

Here the point is different, imagine that the rear wheels of the car rotate forward, and the front wheels backward, PRESENTED? and so for any car enthusiast such a scheme proposed by "experts" for "races" will only cause a loud crazy rzhach or fingers at the temple , but in the field of helicopter engineering, everyone with a smart look offers such a prodigy.

As for the "supersonic blade tips", this is a problem from another area only partially related to the problem of creating a high-speed helicopter.

[Chaldon48]

But it is known that the main obstacle to increasing speed are rotors.

[garri-lin]

Finally. Velocity only synchroper with asymmetric blades or multicopter. A synchropper is preferable due to a smaller midship. Or a classic with the mechanization of the blades and this is already an absurdity. The price will be sky-high.

[Piramidon]

I am interested in such a question. What, in principle, will change the additional 50-70 km / h? After all, this is not something that added the use of jet engines in aircraft construction in the transition from piston engines, when the speeds doubled.

[Grigory_45]

not 50-70, but an increase of more than a hundred km / h - in relation to the fastest serial helicopters.

Fundamentally, nothing, since jet supersonic engines have not abolished subsonic and screw engines.
Tactically - gives an advantage. Faster delivery, faster support for ground troops, etc.

The question is different: at what cost will the speed increase be achieved?

[Monar]

Why 50-70?

the maximum speed of modern rotorcraft usually does not exceed 300-350 km / h

And further down the text -

increase the speed of a combat helicopter up to 600 km / h

All the same, the difference is slightly larger. Yes, and the first jet piston letaki 2 times not overtaken.

So far, even at experimental speeds, barely exceeded 400 km / h.

[Monar]

Sikorsky already wants 550 in the future.
The only thing that confused me in the article was the timing. Humble opinion - no earlier than the 30th year.
And in vain you are so neglecting the difference of 50 km / h. For orders of 350, this is already 14% (if I correctly calculated) the increase.

guaranteed to gain 600, and most likely more.

[voyaka uh]

If you fold the screw (so as not to interfere with speed) and add a small jet engine and wings, then it is quite possible to reach 600 or even more km / h.

ento is no longer a helicopter in the usual sense. A vertically taking off and landing plane. With the propeller folded, the machine loses all the maneuverable advantages of a helicopter, turning into not the most successful aircraft.

[Elephant]

Quote: Gregory_45

It all depends on the need to perform specific tasks, for example, fast delivery of troops or cargo to an inaccessible area (a clearing in the forest, a ship, a golf course ...), where a classic plane cannot land / take off.

[Grigory_45]

those. they again invent a tiltrotor, only coming in from the other side

[Operator]

We are talking about the patent RU168554U1 for the utility model "High-speed combined helicopter (rotorcraft)" https://patents.google.com/patent/RU168554U1/ru

The novelty lies in the transition from helicopter mode (lift is created by the rotor) to aircraft (lift is created by the wing) when the speed reaches 400 km / h. A single turbofan engine in the first case rotates a screw, in the second case - a fan.

The utility model will not take off - the air flow descending from the main rotor will press on the wing of a large area and turn over the structure of Mikheev, Nosov and Petrosyan.

[Blackmokona]

Ie version of a convertiplane

[Operator]

No - rotorcraft variant (main rotor + wing + pusher fan).

A tiltrotor is an aircraft with rotary bearing / pulling screws such as the American V-22 Osprey.

[Azazelo]

It will be interesting to see.

[yehat]

Quote: voyaka uh

just right, is it called a helicopter if the helicopter pops up only on takeoff and landing?
How is this circuit fundamentally different from a vertical penguin?

[Elephant]

Fundamentally, the circuit is no different. But for some reason, I immediately have a question - why do the largest foreign corporations deal with turntables?

[Tarasios]

The speed of the helicopter is limited by its main "feature" - the lifting screw. Taking into account the tendency to accelerate helicopters with stupid reactive engines and install, albeit small, wings (for attachments) that have their own lift, at such high speeds, I think, it is worth considering a completely different approach. For example, the blades are fixed in one position, say, with a deflection backward, and then the helicopter operates in airplane mode. Aerodynamics, plumage of the same blades, etc. - everything is solvable.

[prodi]

helicopter rotor blades are long, flexible, as light as possible, and gain stiffness only due to centrifugal force.
stiffer, shorter and with wider blades (much less efficient) - this is Osprey

[gridasov]

The logic of such designers is amazing, which thinks in terms of primitive addition and addition. We must work with energy density and the creation of appropriate devices and propulsors.

Other times, other morals. But unusual, yes.

[beeper]

The whole thing about "high speed" is in the NON-SYMMETRIC (in flight) lift of the helicopter main rotor (s)!
As the speed of the helicopter increases, the lift force on the "oncoming (relative to the oncoming air flow)" rotor blades increases, and on the "runaway" blades, accordingly, it decreases!
And, due to (proportional to the increase in speed) an increase in this difference between them, the helicopter shows an ever greater tendency to roll and overturn on the "runaway" side, which can be somehow compensated (at speeds up to 350-370 km / h) by equipping rotary-wing aircraft also with small lifting wings - high-speed MI-24 is an example of this! Either using a "coaxial scheme" or "synchropter", where the "oncoming" blades are symmetrical relative to the longitudinal axis of the aircraft and make it possible to slightly increase the cruising speed.
Correctly stated in the comments of colleagues that the rotor speed is infinite and a further increase in the speed of helicopters is possible only in an airplane, using additional marching propellers, and the rotor blades themselves are like wings or folding them along the axis of the aircraft (and the incoming flow) and using constant (or extendable) wings!
It would be interesting to look at this "patented scheme", which provides an increase in the speed of the helicopter of the "coaxial scheme" more (how much "more" ???) 600 km / h, how is it so fundamentally different from the already known similar ones ?!

[garri-lin]

All that I read in the comments I read in childhood in the journal Young Technician. 30 years have passed and nothing has changed. All the same arguments.

[Avior]

There, at the top of the patent.
Nothing supernatural - takes off by helicopter, but it also has wings of an airplane type, at a speed of about 400 it goes into airplane mode.

[beeper]

In my youth, I had a moment of passion for operating models of helicopters (and I almost became a helicopter pilot myself - there was a 100% chance of being enrolled in the school, but fate turned out differently), so I delved into, with youthful enthusiasm, into the subtleties of design, piloting and aerodynamics flight of these interesting machines, I watched the flights of "Ka" and "Mi" for a long time, sat in the pilot training cabins, collected bit by bit any information about the then classified Mi-24, the lightweight prototype of which showed a speed record for helicopters! I know how difficult it was to reach even overcoming the 300 km / h line of helicopter speed and increase each kilometer over "three hundred", and now "over 600 km / h" ?!
Of course, I was interested in the "patented solution" - and suddenly something interesting, breakthrough ... but at the top, as the respected colleague Avior previously wrote, photos and videos have already been posted, so I did not see anything unusual, all these design solutions use well-known experimental developments of the 60s of the last century, only at the current level of technology and construction materials!
I was lucky in my childhood and adolescence to communicate with aviation specialists, who began their career in aviation from the first Soviet gliders of the early 20s and all the years lived in aviation, were professionally engaged in it, wrote textbooks and prepared young air frames, so they looked far into the future and these are all current ones. " promising schemes "were already in their drawings then (except that there was no question of" stealth technologies "and" chopped flat surfaces "then - I was taught to achieve" smooth streamlining of all profiles and surfaces "of the aircraft according to the" area rule ").

Sikorsky S-97 Raider 444 km per hour. Sikorsky X2 - 460 km / h. SB> 1 Defiant - 460 km per hour. V-280 Valor-520 km per hour. Eurocopter X3 - maximum speed - 472 km / h. In the development of the enemy helicopters 800-900 km per hour. Are ours just starting to itch? They are fantasizing. It takes about 10 years to develop a helicopter to launch into a small series. In 10 years, our state-of-the-art helicopters will be 10-15 years old. And there are very big doubts that these developers are capable of doing at least 400 km per hour. For 30 years they have not developed anything for a high-speed one, they just thought. Even if they attach 3 pushing screws and make the retractable wings, the enemies will not catch up. And the cost of the helicopter will be like two American ones. Greed and stupidity will win, for sure. But there is a solution. There is a super technology: patent No. 149598 "Device for controlling the flow around an aircraft." The aerodynamic drag is reduced to zero. Reaching 1000 km per hour in the atmosphere is real. Increases the lifting force of the propeller two to three times. There are the latest technologies: gravity control (vertical movement), inertia control (the pilot does not feel acceleration). It is possible to make an apparatus that surpasses helicopters many times in TX. And the USA has already made such devices.

with the development of new technologies for creating multi-element structures and materials, you can already create
radically more advanced devices
