The invention discloses a rotor cabin helicopter with a directional propeller under a rotor in damping connection. The rotor cabin is a lift unit composed of an engine or a motor, a transmission, a transmission device, the rotor, a blade waving device, a collective pitch and periodic pitch controller, a short cross arm, the directional propeller and the like, a damping component is composed of a plurality of rubber dampers or damping rubber dampers, a flight control system, a cockpit, a cargo hold and the like are arranged in the fuselage cabin, the undercarriage is arranged at the lower part of the fuselage cabin or the rotor cabins, the fuselage cabin and the plurality of rotor cabins are connected by connecting the fuselage cabin with the bottom of the damping component, and the longitudinal axis of the fuselage cabin is parallel to the longitudinal axis of each rotor cabin, so that the helicopter with the rotor cabins connected in a damping manner through the propellers under the rotors is formed. The direction propellers under the rotor wings control the direction and provide pulling force for forward rapid horizontal flight, the damping component blocks vibration mutual transmission of the rotor wings of all the rotor wing cabins, resonance is prevented, the structure is simple, control is flexible, and the helicopter is suitable for the fields of transportation, agricultural operation, aerial photography and the like.
一种旋翼下方向螺旋桨减震连接旋翼舱直升机,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、短横臂、方向螺旋桨等构成的一个升力单元,减震构件由多个橡胶减震器或阻尼橡胶减震器构成,机身舱内设置飞行控制系统、驾驶舱和货舱等,起落架设置在机身舱、或旋翼舱的下部,机臂通过连接减震构件的底部,将机身舱、多个旋翼舱连接,机身舱的纵轴和各个旋翼舱的纵轴平行,构成旋翼下方向螺旋桨减震连接旋翼舱直升机,旋翼下的方向螺旋桨操纵方向和提供向前快速水平飞行的拉力,减震构件阻断了各个旋翼舱的旋翼的震动互传,防止共振的发生结构简单,操纵灵活的优点,适合运输,农业作业,航拍等领域。
