The invention provides an autorotorcraft adopting a vector propulsion tail rotor, which belongs to the technical field of aviation aircrafts, and comprises a fuselage, a rotor, an engine, a propeller, a horizontal transmission shaft, an inclination angle controller, a common universal joint, a vertical transmission shaft, a steering mechanism and a double-joint universal joint, the inclination angle controller is centrally mounted at the cabin top of the fuselage; the upper end of the common universal joint penetrates through the inclination angle controller and is coaxially and fixedly connected with the rotor shaft, and the lower end of the common universal joint is coaxially and fixedly connected with the vertical transmission shaft; the engine provides power for the vertical transmission shaft and the horizontal transmission shaft; the propeller is fixedly connected with the horizontal transmission shaft through the double-joint universal joint and installed at the tail of the fuselage, the double-joint universal joint can drive the propeller to deflect along with the steering mechanism to change the thrust direction of the propeller, and the torque of the thrust on the lateral component of the fuselage relative to the mass center is used for counteracting the reverse torque generated by rotation of the rotor wings. Forward thrust is formed by longitudinal component force of the machine body. The vertical take-off and landing and hovering functions of the autorotorcraft are expanded.
本发明提出一种采用矢量推进尾桨的自转旋翼机,属于航空飞行器技术领域,包括机身、旋翼、发动机、螺旋桨、水平传动轴,还包括倾角控制器、普通万向节、竖直传动轴、转向机构、双关节万向节;倾角控制器居中安装在机身舱顶;普通万向节的上端贯穿倾角控制器,与旋翼轴同轴固连,下端与竖直传动轴同轴固连;发动机为竖直传动轴、水平传动轴提供动力;螺旋桨通过双关节万向节与水平传动轴固连并安装于机身尾部,双关节万向节可带动螺旋桨随转向机构偏转改变螺旋桨推力指向,该推力在机身侧向分力相对质心的力矩用于抵消旋翼旋转产生的反转扭矩,在机身纵向分力形成前进推力。本发明拓展了自转旋翼机垂直起降、悬停功能。
