METHOD FOR ROTATING MAIN ROTOR AND CORRESPONDING DEVICE Russian patent published in 2018 - IPC B64C27/10 B64C27/605 

FIELD: aviation.

SUBSTANCE: method for rotating the main rotor includes receiving a flight control command, receiving actual rotational states of first engines corresponding to the first actuating mechanisms, and actual rotational states of the second engines corresponding to the second actuating mechanisms. Then the required first rotational states of the first engines are determined in compliance with the flight control command and actual rotational states of the first engines. The required second rotational states of the second engines are determined in compliance with the flight control command and the actual rotational states of the second engines. The first engine is controlled to provide its rotation in the corresponding first rotational state for turning the clamping elements of the first blade relative to the bushing of the lower rotor propeller. The second engine is controlled to provide its rotation in the corresponding second rotational state for turning the clamping elements of the second blade relative to the bushing of the upper rotor propeller.

EFFECT: on course control of coaxial helicopter is provided.
