The invention relates to the technical field of low-altitude aircrafts, in particular to a lift device improved helicopter which comprises a helicopter body and a lift device arranged at the top of the helicopter body, and the lift device comprises a supporting installation part, a main motor, a rotary disc and two main rotors or propellers; the main motor is mounted on the aircraft body through a supporting mounting part, the two main rotors or propellers are arranged on the turntable, the turntable is connected to a rotor of the main motor, and the two main rotors or propellers synchronously revolve along with the turntable; a synchronizing mechanism is arranged between the two main rotors or propellers, so that the synchronous rotation of the two main rotors or propellers is realized. The main motor drives the rotating disc to rotate and drives the two main rotors or propellers to synchronously revolve for the first time, in the revolution process, the two main rotors or propellers achieve autorotation to form secondary rotation, and the revolution and autorotation form a superposed rotation effect, so that the utilization efficiency of air flow is greatly improved; and miniaturization of the rotor type aircraft is facilitated.

    本发明涉及低空飞行器技术领域,具体指一种升力装置改进型直升机,包括机体和设于机体顶部的升力装置,所述升力装置包括支撑安装部、主电机、转盘以及两个主旋翼或螺旋桨;所述主电机通过支撑安装部安装于机体上,两个主旋翼或螺旋桨设于转盘上,所述转盘连接于主电机的转子,两个所述主旋翼或螺旋桨随转盘同步公转;两个所述主旋翼或螺旋桨之间设有同步机构,从而实现两个主旋翼或螺旋桨同步自转。本发明主电机驱动转盘旋转,带动两个主旋翼或螺旋桨同步公转,实现第一次旋转,在公转的过程中,两个所述主旋翼或螺旋桨实现自转,形成第二次旋转,公转和自转形成叠加旋转效果,极大地提高了空气流的利用效率,有利用旋翼型飞行器的小型化。
