这是一种无尾桨系统的武装直升机,由于它采用了“桨扇共轴反转”的设计,所以不存在单旋翼直升机那种需要用尾桨来平衡旋翼运动所产生的反作用力矩问题。 “桨扇共轴”中的“桨”是指旋翼桨叶,而“扇”是指升力风扇。所谓“桨扇共轴”就是说旋翼桨盘和升力风扇在同一条轴线上。因为旋翼和风扇的旋转方向是相反的,而且转数又相差悬殊,所以两者的反作用力矩可以相互抵消。“桨扇共轴”直升机的动力系统主要是由发动机系统、变速/传动系统、旋翼系统、升力风
This is a type of helicopter with no tail rotor system. Because it adopts the design of “propeller shaft coaxial inversion”, there is no single-rotor helicopter that needs the tail rotor to balance the reaction torque generated by rotor motion problem. “Paddle ” in “Paddle Coaxial” refers to the rotor blade, and “fan” refers to the lift fan. The so-called “propeller fan coaxial” means that the propeller rotor and lift fan are on the same axis. Because the rotational direction of the rotor and the fan is the opposite, and the difference between the rotation and the disparity, so the two reaction torque can offset each other. “Oar fan coaxial ” The helicopter power system is mainly composed of the engine system, transmission / transmission system, rotor system, lift wind
