Abstract

The invention provides an electronically-controlled electric rotor wing brake system which is used for a rotor wing brake of a helicopter. The brake system includes a control system 1, an electric mechanism component 2, a connection component 3 and a rotor wing brake stop mechanism. The electric mechanism component 2 includes a driving mechanism 8; the control system 1 is electrically connected with the driving mechanism 8 and is used for controlling the driving mechanism 8 to move; an output shaft 80 of the driving mechanism 8 is in threaded connection with one end of the connection component3, the output shaft 80 of the driving mechanism 8 rotates to drive the connection component 3 to move in the axis direction; and the other end of connection component 3 is fixedly connected to the rotor wing brake stop mechanism, the connection component 3 moves in the axis direction, the rotor wing brake stop mechanism is driven to move, and the rotor wing brake stop mechanism stops a rotor wing.

Description

technical field [0001] The invention belongs to the technical field of helicopter transmission design and relates to an electronically controlled electric rotor braking system. Background technique [0002] The function of the helicopter rotor brake system is that when the helicopter is on the ground, when the engine is stopped, the rotor brake is used within the specified rotor speed. It can shorten the rotor stop time, quickly brake the blades, and park the helicopter on the ground. Keep the rotor blades stationary. At present, most of them adopt two structures of mechanically controlled mechanical brakes and mechanically controlled hydraulic brakes. [0003] Mechanical control The mechanical brake structure generally adopts the combination of cockpit rotor brake mechanical control handle, linkage reversing structure, rotor brake control cable, elastic actuation mechanism, and mechanical rotor brake device. Through the operation of the driver, the brake is driven. The br...
