Promising high-speed helicopter (PSV)

Formed a general view and layout, as well as calculated aircraft performance characteristics of the aircraft, according to the developer’s presentation

MOSCOW, April 24th. / Tass /. Kamov JSC (part of the Russian Helicopters holding) has developed a conceptual design of a prospective high-speed helicopter of a synchroter (or synchroopter) scheme with two main and one pusher propellers. The maximum design speed of the car reaches 420 km / h, follows from the presentation of the developer, a copy of which is available to TASS.

A synccopter is a helicopter, in which two screws are mounted at a short distance from each other and rotate in opposite directions, while the trajectories of their blades intersect, the screws rotate "overlap". In order for the blades not to collide, their rotation is mechanically synchronized.

The simulation showed the advantage of such a scheme - the efficiency is higher by 4% compared to the single and coaxial schemes, there is no disruption of the air flow from the screws, which occurs at high speeds. It is because of this effect that the helicopters of the classical schemes have reached their speed limit. Also, to increase the speed in the tail, a pushing screw was installed, the blades received tips of a special form, and their speed of rotation was reduced from 220 to 180 m / s.

According to the presentation materials, the design result was a high-speed passenger helicopter with the following characteristics: take-off weight of 6500 kg, payload mass of 1000 kg, cruising speed of 357 km / h, maximum speed of 420 km / h, static ceiling of 4700 m, dynamic ceiling of 5600 m, range of 1228 km.

Kamov don't throw the towel

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

In Russia, they found a way to increase the speed of a combat helicopter to 600 km / h. This was reported by TASS with reference to the leadership of JSC Kamov.



The general designer of Kamov JSC Sergey Mikheev claims that his company managed to find a solution with which it is possible to increase the speed of a combat helicopter to 600 km / h. Mikheev reported this to 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 are behind the requirements that exist." The designer mentioned Boeing, which together with Sikorsky Corporation creates a promising car at 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 in 2022. 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, 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 overcome the bar of 400 km / h: these are S-97 Raider in the USA and Eurocopter X3 in Europe.

Pusher propellers are not new... Autogyros have them as standard propulsion with a free spinning rotor for lift which limits them to relatively low speeds but if the main rotor can be spun up via the engine they can have very short take off and landing runs.

The aircraft competing with the Apache had a pusher propeller too I seem to recall and plenty of Kamov and Mil designs have had a bit of variety in rotor arrangements too.

Just the first minute of the video... a glance at the basic design of this aircraft suggests that it will likely use turbofan engines to power the main rotors for take off and landing but for normal flight the main rotor blades will be feathered (ie set for minimum drag and generate very little lift) and the aircraft will basically fly with the two jet engines and the wings for lift like a normal plane... much easier and safer than a tilt rotor and with the speed of a plane rather than a helicopter... so capable of well beyond 500km/h limit for super fast helo designs.

This seems to me to be a jet airplane with an autogyro attached to allow vertical takeoff and landing... very clever and removes the problems of needing to rotate large rotor blades like on a tilt rotor... it would still need a complex gearbox to power each rotor independently so if one engine fails the other engine can run both rotors, but Kamov have an excellent history of fantastic gearbox technology... if anyone can make it work it would be them.

For all we know they might change the design...

Hope they are allowed to develop this. I remember some time ago they said they were going to develop a high speed helicopter based on the Ka-52, but this would be better than my wildest dreams

I guess this follows the same concept of jet-propelled helo that they leaked before, but using the Ka-52 as a base for a possible demonstrator.
