The invention discloses a helicopter tail wheel locking system and a tail wheel control method. The system comprises a tail wheel lock, a tail starting buffer device, an electromechanical management unit, an avionics display unit, an indicator lamp box and a switch. The electromechanical management unit is electrically connected with the switch and a tail wheel lock mounted on the tail starting buffer device respectively; according to the helicopter tail wheel locking system, a pilot operates a switch and sends a tail wheel lock control signal to the electromechanical management unit, and the electromechanical management unit transmits the received control signal to the tail wheel lock so as to drive an output shaft of an electric mechanism in the tail wheel lock to execute corresponding motion; therefore, the mechanical lock and the lock pin which are in linkage in the tail wheel lock are driven to generate linkage motion, and electric locking, electric unlocking or electric locking after manual unlocking of the tail wheel lock is achieved.

    本发明公开一种直升机尾轮锁定系统和尾轮操纵方法,系统包括:尾轮锁、尾起缓冲装置、机电管理单元、航电显示单元、提示灯盒和开关;机电管理单元分别与开关和安装在尾起缓冲装置上的尾轮锁电连接;直升机尾轮锁定系统通过飞行员对开关操作,向机电管理单元发送尾轮锁控制信号,由机电管理单元将接收到的控制信号传递到尾轮锁,以驱动尾轮锁中的电动机构的输出轴执行相应运动,从而带动尾轮锁中联动的机械锁和锁销产生联动运动,实现尾轮锁的电动锁定、电动解锁、或手动解锁后的电动锁定。
