The invention provides a multi-mode combined type high-speed helicopter with a rotating engine, which belongs to the technical field of helicopters and comprises a helicopter body, rotors, a power system, a transmission system and propellers. Only the rotational degree of freedom in the direction of an output shaft is reserved between an engine and a fuselage in the power system, torque transmission between the engine and the fuselage is isolated, and reverse torque generated by the rotation of rotors and the action of air is transmitted through a transmission system, only drives the engine to rotate reversely and is not transmitted to the fuselage, and a tail rotor is not needed to balance the torque; the lift fan and the engine are coaxially and fixedly installed in the output axial direction, the lift fan synchronously and reversely rotates along with the engine to generate additional lift force, and reverse torque generated when the rotor wing, the engine and the lift fan assembly reversely rotate to act on air is mutually balanced. A tilting mechanism is installed on the helicopter body, and switching of the helicopter and the autorotorcraft is achieved under cooperation of a transmission system. While high-speed flight of the helicopter is achieved, reliability, economical efficiency and safety are effectively improved, and the service life is effectively prolonged.

    本发明提出一种发动机随转多模复合式高速直升机,属于直升机技术领域,包括机身、旋翼、动力系统、传动系统,还包括螺旋桨;动力系统中的发动机与机身间只保留绕输出轴方向的旋转自由度,隔离发动机与机身间扭矩传递,旋翼旋转与空气作用产生的反转扭矩经传动系统传递只驱动发动机反向旋转,不传递至机身,无需尾桨平衡扭矩;升力风扇与发动机沿输出轴向同轴固定安装,通过升力风扇随同发动机同步反向转动产生附加升力,旋翼、发动机与升力风扇组合体反向旋转作用于空气产生的反转扭矩相互平衡。机身上安装倾转机构,在传动系统配合下实现直升机、自转旋翼机切换。本发明实现直升机高速飞行的同时,有效提升可靠性、经济性、安全性和使用寿命。
