FIELD: aircraft engineering.
SUBSTANCE: transmission of a multi-rotor aircraft. The hydraulic drive contains a pumping station, including a main adjustable pump and a feed pump with a block of non-return safety and pressure reducing valves, four hydraulic motors, pressure and drain hydraulic lines. The output shaft of each hydraulic motor is connected to its corresponding propeller. Additionally, the hydraulic drive contains constant differential pressure valves, throttling spools and “or” valves. Moreover, the constant differential pressure valves are connected to the throttling spools, and also through the “or” valves to the pump regulator.
EFFECT: improved flight stability and energy efficiency of a multi-rotor aircraft are achieved.
