The invention relates to a side-tipping longitudinal double-propeller composite helicopter which comprises a fuselage, a power device, a transmission device, two top propeller rotors, two tilting mechanisms, a transmission mechanism, propulsion propellers, a control system and the like. A movable shaft driver is arranged in the transmission device; the two top propeller rotors are arranged at theupper part of the fuselage along the longitudinal axis of the fuselage; hard propeller blades are adopted as propeller blades; the rotating directions of two top propeller rotors are opposite; and thedistance between two rotor shafts is larger than the radius of the top propeller rotors. The tension of the rotors is adjusted by adjusting the total distance of the propeller blades, the two top propeller rotors can tilt leftwards and rightwards respectively, and tilting is controlled by the tilting mechanisms. The propulsion propellers generate forward and backward propulsive force to the fuselage; and the control system controls five mechanisms, namely a front top propeller rotor total distance adjusting mechanism, a front top propeller rotor tilting mechanism, a rear top propeller rotor total distance adjusting mechanism, a rear top propeller rotor tilting mechanism and a propulsion propeller total distance adjusting mechanism.
本发明侧倾纵列双桨复合直升机,包括机身、动力装置、传动装置、两副顶桨旋翼、两个倾转机构、传动机构、推进桨和操控系统等。传动装置中设置动轴传动器;两副顶桨旋翼沿机身纵向轴线设置于机身上部,其螺旋桨叶采用硬桨叶,两副顶桨旋翼转动方向相反,两旋翼轴之间的距离大于顶桨旋翼半径,通过调节螺旋桨叶总距来调节旋翼拉力,两副顶桨旋翼可以向左侧及向右侧各自倾转,倾转受倾转机构控制;推进桨对机身产生向前及向后推进力;操控系统操控五套机构,即前顶桨旋翼调总距机构、前顶桨旋翼倾转机构、后顶桨旋翼调总距机构、后顶桨旋翼倾转机构和推进桨调总距机构。
