The invention discloses a coaxial tilting three-rotor blade helicopter. The coaxial tilting three-rotor blade helicopter comprises a helicopter body (1) formed by assembling a pair of front rotor arms(10) and a pair of rear rotor arms (12) in a T shape. The power output ends of the pair of front rotor wing arms (10) are respectively provided with main rotor wings (4) which are in transmission with power transmission shafts (15) in the front rotor wing arms (10) and generate thrust. The power output ends of the pair of rear rotor arms (12) are provided with tail rotor wings (5) which are in transmission with the power transmission shafts (15) in the rear rotor arms (12) and generate thrust. The coaxial tilting three-rotor blade helicopter has the advantages that power of one engine is output to the three rotors and distributed on the two sides and the tail portion of the helicopter body, and the maneuverability, the lift force and the flight speed are greatly improved.

    一种共轴倾转三旋翼桨叶直升机,包括由一对前旋翼臂(10)和后旋翼臂(12)呈T形拼装而成的机身(1),一对前旋翼臂(10)的动力输出端分别设有与前旋翼臂(10)内的动力传动轴(15)传动并产生推力的主旋翼(4),后旋翼臂(12)的动力输出端设有与后旋翼臂(12)内的动力传动轴(15)传动并产生推力的尾旋翼(5),本发明优点是:将一个发动机的动力输出到三个旋翼上,并分布在机身的两侧和尾部,机动性、升力和飞行速度大幅提升。
