The invention belongs to the technical field of aircraft design, and particularly relates to a high-speed tilt rotor helicopter with trapezoidal distributed rotors, the helicopter adopts an overlook trapezoidal four-rotor configuration, and the helicopter comprises two groups of front tilt rotors and two groups of rear rotors; the fuselage system is designed to be a streamline fuselage, the power system comprises two turboshaft engines, and the front turboshaft engine provides power with the same torque and opposite rotation directions for the tilting rotor wings through a centrifugal clutch, a transmission shaft and a speed reducer; the rear turboshaft engine provides high-rotating-speed strong thrust for the rear rotor wing through a clutch and a transmission shaft. According to the helicopter provided by the invention, the aircraft can be in two attitudes of a helicopter mode and a fixed wing mode by controlling the angle of the nacelle, and helicopter mode takeoff, fixed wing mode takeoff, transition flight, fixed wing mode high-speed flight, aerial fixed wing mode switching to helicopter mode landing and fixed wing mode landing can be realized.
本发明属于飞行器设计技术领域,具体涉及一种梯形分布旋翼的高速倾转旋翼直升机,所述直升机采用俯视梯形四旋翼构型,包括两组前置倾转旋翼和两组后置旋翼;起落架,机身系统设计为流线型机身,动力系统包括两台涡轴发动机,前涡轴发动机通过离心式离合器、传动轴、减速器分别为倾转旋翼提供相同扭矩相反旋转方向的动力;后涡轴发动机通过离合器、传动轴提供后旋翼的高转速强劲推力。本发明所提出的直升机通过控制短舱角度可使飞行器处于直升机模式、固定翼模式两种姿态,能实现直升机模式起飞、固定翼模式起飞、过渡飞行、固定翼模式高速飞行、空中固定翼模式切换至直升机模式降落和固定翼模式降落。
