The invention relates to a tandem helicopter with two sets of coaxial reversal double rotors. The tandem helicopter comprises a helicopter body, a power device, a transmission shaft, two sets of coaxial reversal circumferential propellers, two sets of double rotors, two tilting mechanisms, a control system and the like. The transmission shaft transmits power from the power device to the coaxial reverse circumferential thruster, and the coaxial reverse circumferential thruster transmits the power to the double rotors. The two sets of double rotors are arranged at the upper part of the fuselage in tandem along the longitudinal axis of the fuselage; the blades are hard blades, the rotating directions of the upper-layer rotor wing and the lower-layer rotor wing of the double rotor wings are opposite, and the pulling force of the rotor wings is adjusted by adjusting the total pitch of the blades. The two sets of double rotors can tilt to the left side and the right side respectively, tilting is controlled by a tilting mechanism, and the maximum tilting angle is limited by the fact that the double rotors do not collide with the fuselage. And the control system comprises but is not limited to a total pitch adjusting mechanism for controlling the two tilting mechanisms and the two sets of double rotors.

    本发明两套共轴反转双旋翼纵列直升机,包括机身、动力装置、传动轴、两套共轴反转周向推进器、两套双旋翼、两个倾转机构和操控系统等。传动轴把动力从动力装置传递到共轴反转周向推进器,共轴反转周向推进器把动力传递到双旋翼。两套双旋翼沿机身纵向轴线一前一后设置于机身上部,双旋翼桨盘向上。桨叶采用硬桨叶,双旋翼的上层旋翼与下层旋翼的转动方向相反,通过调节桨叶总距来调节旋翼拉力。两套双旋翼可以向左侧及向右侧各自倾转,倾转受倾转机构控制,倾转最大角度以双旋翼与机身不碰撞为限。操控系统,包括但不限于控制两个倾转机构和控制两套双旋翼的调总距机构。
