The invention discloses a flight power device of a helicopter, belongs to the technical field of helicopter production, and aims to solve the technical problems that 1, how to disperse the bearing capacity of a propeller rotating shaft; 2, how to reduce the fatigue strength of the blade; and 3, how to improve the load capacity of the helicopter and improve the flight speed. According to the technical scheme, a fixed annular rail protection cover is installed on the periphery of the tail end of a blade, a roller at the tail end of the blade does circular motion in a rail, the distance between rails is changed, the roller at the tail end of the blade is compressed to deflect, torsional moment is generated, a fan blade of the blade is driven to deflect, and downward or backward thrust is generated; the wind direction is adjusted through a wake flow control system, and thrust in the anticlockwise direction, the clockwise direction, the upward direction, the downward direction, the leftward direction, the rightward direction, the forward direction and the backward direction is generated. The device is composed of a rotating system, a blade system, a track protection system, a wake flow control system and the like. The device is suitable for flight power control devices of military and civil helicopters.
一种直升机的飞行动力装置,属于直升机生产技术领域,所要解决的技术问题:1.如何分散螺旋桨转轴的承载力;2.怎样降低叶片的疲劳强度;3.如何提高直升机的载重量、提高飞行速度。技术方案要点是:在叶片末端周边安装固定的环形轨道保护罩,让叶片末端的滚轮在轨道内做圆周运动,改变轨道间的距离,压缩叶片末端滚轮偏转,产生扭力矩,带动叶片扇片偏转,产生向下或向后的推力;通过尾流控制系统,调整风向,产生逆时针、顺时针、上、下、左、右、前、后方向的推力。该装置由旋转系统、叶片系统、轨道保护系统、尾流控制系统等组成。该装置适用于军用、民用直升机的飞行动力控制装置。
