The invention relates to the technical field of flight equipment, in particular to a swash-plate-free helicopter and a control method thereof.The swash-plate-free helicopter comprises a helicopter body, a paddle motor, a control system, a first paddle and a second paddle, the paddle motor and the control system are arranged on the helicopter body, and the first paddle and the second paddle are distributed on the two opposite sides of the paddle motor; a first swing body and a second swing body are hinged to the two opposite sides of the rotating support respectively, and the first paddle and the second paddle are connected to the first swing body and the second swing body respectively. The first swinging body and the second swinging body are respectively connected with the first paddle and the second paddle to generate forward or backward swinging in the rotating direction of the paddle motor, so that the screw pitches of the first paddle and the second paddle are changed. According to the invention, a swash plate and a steering engine in a traditional unmanned helicopter structure can be canceled, but turning flight of the helicopter can still be controlled, the manufacturing cost of the product is effectively reduced, the load of the helicopter body is reduced, the cruising ability is improved, the structure is more simplified, and the service life of the product is prolonged.

    本发明涉及飞行设备技术领域,尤其涉及一种无斜盘直升机及其控制方法,包括机体、设置在机体上的桨叶电机和控制系统以及分布在桨叶电机相对两侧的第一桨叶、第二桨叶,桨叶电机传动设置有旋转支架,旋转支架的相对两侧分别铰接有第一摆动体和第二摆动体,第一桨叶和第二桨叶分别连接在第一摆动体和第二摆动体上;通过第一摆动体和第二摆动体分别连带第一桨叶和第二桨叶在桨叶电机的旋转方向上产生向前或向后的摆动改变第一桨叶和第二桨叶的螺距。本发明能取消传统无人直升机结构当中的斜盘和舵机,但仍然可以实现控制直升机的变向飞行,有效降低产品的制造成本并降低机体的负载,提升续航能力,并且结构更加简化,有利于延长产品的使用寿命。
