MULTI-ROTOR FLYING PLATFORM WITH HYDRAULICALLY DRIVEN ROTORS Russian patent published in 2023 - IPC B64C27/20 B64C27/08 B64C27/12 B64D35/04 

FIELD: aviation.

SUBSTANCE: designs of multipropeller aircraft. The multirotor platform contains a drive engine, high and low pressure hydraulic lines made in the form of closed circuits, to which adjustable hydraulic motors are connected and adjustable pumps through check valves. Each adjustable pump is equipped with a pressure control mechanism. Each adjustable hydraulic motor is equipped with an electro-hydraulic mechanism for controlling the position of the regulating body and drives the main rotor corresponding to it through the gearbox. Changing the speed of rotation of the main rotor is carried out by an adjustable hydraulic motor. The multirotor platform is equipped with a hydraulic drive control system, consisting of a hydraulic drive control device, sensors for the rotation speed of the main rotors, rotation of the drive motor shaft, sensors for the position of the regulating bodies of adjustable hydraulic motors and a pressure sensor in the high pressure hydraulic line.

EFFECT: high-quality controllability of the aircraft, improvement of the dynamics of work, increase in efficiency and reliability, minimum weight and size characteristics.
