The invention provides a rotor cabin tail thrust variable pitch propeller damping connection rotor cabin helicopter. An undercarriage is arranged on the lower portion of a fuselage cabin close to the gravity center, arms are arranged on the top of the fuselage cabin, and the fuselage cabin and two or more than two even number of rotor cabins are connected by connecting the arms with the bottom of a damping assembly. Each rotor cabin is a lift unit composed of an engine or a motor, a speed changer, a transmission device, rotors, a paddle waving device, a total pitch and periodic pitch controller, a tail arm, a tail thrust variable pitch propeller and the like, the connecting line of the rotating centers of the rotors is a straight line or a square, and the reaction torques of the rotors are mutually offset or approximately offset. The rotating face of the tail thrust variable-pitch propeller arranged in the rotor cabin is perpendicular to the horizontal plane, the normal of the rotating face is parallel to the longitudinal axis of the rotor cabin, the tail thrust variable-pitch propeller of the rotor cabin manipulates the course on one hand and provides thrust for rapid horizontal flight on the other hand, resonance is prevented through the damping assembly, manipulation is flexible, and the rotor cabin is suitable for fields of transportation, agricultural operation, and aerial photography.

    一种旋翼舱尾部推力变距螺旋桨减震连接旋翼舱直升机,重心附近机身舱下部设置起落架,机身舱顶部设置机臂,机臂通过连接减震组件的底部,将机身舱、两个或两个以上偶数旋翼舱连接,旋翼舱是由发动机或电机、变速器、传动装置、旋翼、桨叶挥舞装置、总距和周期变距控制器、尾臂、尾部推力变距螺旋桨等构成的一个升力单元,各个旋翼的旋转中心的连线是一条直线或是正方形,各个旋翼的反扭矩相互抵消或接近抵消,设置在旋翼舱的尾部推力变距螺旋桨的旋转面垂直于水平面,旋转面法线平行于旋翼舱纵轴,旋翼舱的尾部推力变距螺旋桨一方面操纵航向,另一方面提供快速水平飞行的推力,减震组件防止发生共振,操纵灵活,适合运输,农业作业,航拍等领域。
