HIGH-SPEED ROTARY-WING AIRCRAFT Russian patent published in 2015 - IPC B64C27/22 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering, particularly, to rotary-wing aircraft designs. The high-speed rotary-wing aircraft has a hull with a wing and a tail beam, lifting and tail rotors with a power plant and two additional air rotors installed on consoles of the wing and each fitted with its own engine. Each additional air rotor with the electric motor is installed in the ring housing located in a through hole in the wing console and installed with a possibility of turn for the placement of an axle of the air rotor vertically or "for flight", according to the selected flight mode. Meanwhile the consoles of the wing are implemented with the rotary trailer parts installed with a possibility of lowering and lifting into an initial position. The turning drive of each additional air rotor and turn of the trailer part of the wing console includes the electric motor installed in the console cavity, a reducer, an output shaft of which is rigidly connected to the ring housing of the additional air rotor, an intermediate reducer, an input shaft of which is rigidly connected to the ring housing of the additional air rotor, and the output shaft, via an engagement-disengagement coupling, connected with a turn mechanism of the trailer part of the wing console.

EFFECT: simplification of control of a high-speed rotary-wing aircraft at transition from the mode take-off-hanging-landing in the mode of high-speed horizontal flight and back is achieved.
