AIRCRAFT WITH MAIN ROTOR WITH ELECTRIC DRIVE FOR ACTUATION OF MAIN ROTOR AND/OR TAIL ROTOR OF THIS AIRCRAFT WITH MAIN ROTOR Russian patent published in 2022 - IPC B64C27/12 B64C27/14 H02K5/04 

FIELD: aircrafts.

SUBSTANCE: aircraft with the main rotor with a hybrid drive for actuation of the main rotor is proposed, where the hybrid drive contains an electric drive and the second drive made as a thermodynamic power machine. The electric drive contains means for connection of the electric drive to a rotor rack connected without possibility of rotation to a transmission drive node of a helicopter rotor for connection without possibility of rotation to the main rotor or a tail rotor. The electric drive is made as an annular electric engine located and fixed coaxially to the rotor rack. The electric drive can be mechanically connected to the drive made as the thermodynamic power machine, so that the electric drive is rotated together with the second drive in a connected state, and, due to this, the electric drive has a possibility of support of the second drive, when actuating the main rotor or the tail rotor and vice versa to form a parallel-connected hybrid drive.

EFFECT: structure is simplified, and weight is reduced.
