GREBENYUCK'S ROTORCRAFT Russian patent published in 2010 - IPC B64C27/22 B64C29/04 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering, particularly to rotorcraft, helicopters. Proposed rotorcraft comprises engine, cab, landing gear, air intake and furl tanks. Rotorcraft rotor represents a biconvex truss to revolve about rotor axis, openings arranged on both sides of rotor center, said openings representing truncated cones with their smaller bases directed inward the rotor. It comprises mounting housing arranged inside rotor, mounting housing stabilisation mechanism representing ring gears with inner gearing coupled by idle gear, mechanism to lock rotor relative to mounting housing. Said mechanism represents a plunger mechanism. Rotorcraft includes also gas steering surface communicated via channels with gas flow distribution channel, in pairs and crosswise. Note that said surface is also coupled, in every pair, by aerodynamic hollow surfaces fitted along rotor diametre to allow them turn around rotor crosswise axis. Aerodynamic surface inside is divided by tight baffle into two compartments communicated with atmosphere. Note that lower compartment communicates, via channel, with gas flow distribution chamber and upper compartment is communicated with air intake via vanes arranged along the edges of rotor lower part exhaust opening to revolve about rotor crosswise axis. Plunger mechanism piston is arranged in mounting housing and rod interacts with locking recesses made in rotor hole wall and gas flow distribution chamber arranged at mounting housing lower part communicated via channel with engine pressure chamber. Rotor lower part is hinged to landing gear, while cab is mounted at rotor top part, above aerodynamic surfaces.

EFFECT: higher safety, increased flight speed and higher maneuverability.
