    Sorry dude, no offense but it sounds like the guy making the video is working things out and learning things as he goes... not sure whether it is you or not...

    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.

    Good analysis
