Abstract

The invention belongs to the field of aircraft design, and relates to an electrically driven helicopter tail rotor transmission system in aircraft design. The system includes a motor, a power source of the motor and a control system; wherein, the motor located at the tail of the helicopter is connected to the tail rotor of the helicopter, the motor is the power source of the tail rotor of the helicopter, and the control system controls the speed of the tail rotor of the helicopter. The electric-driven helicopter tail rotor transmission system of the present invention replaces the mechanical transmission by the electric drive type transmission, and replaces the traditional tail rotor pitch rod mechanism by changing the tail rotor speed, so that the structural weight can be reduced, the energy utilization rate of the engine can be improved, and the efficiency of the tail rotor transmission system can be improved. Assembling maintainability and reducing the overall noise and vibration level of the helicopter have great practical application value.

Description

technical field [0001] The invention belongs to the field of aircraft design, and relates to an electrically driven helicopter tail rotor transmission system in aircraft design.
