The invention relates to the technical field of aircrafts, and concretely relates to a single-layer four-rotor aircraft. The aircraft comprises a rack, a power device is arranged on the rack, flying devices are arranged at the front end and the rear end of the rack respectively, each flying device comprises a supporting rod, a U-shaped connecting rod and flying units arranged at the two ends of the U-shaped connecting rod, and the supporting rods are fixed to the rack. The center of the U-shaped connecting rod is hinged to the supporting rod, each flight unit comprises a steering engine, a rotating bearing and rotor wings symmetrically arranged on the two sides of the rotating bearing, the rotating bearings are fixed to the ends of the U-shaped connecting rod through the steering engines,and the power device is connected to the U-shaped connecting rod and can drive the U-shaped connecting rod to move up and down. The power device drives the U-shaped connecting rod to move up and downso as to drive the flight units at the two ends of the U-shaped connecting rod to move up and down, the rotor wings can rotate around the rotating bearings in the circumferential direction, the rotating speed becomes higher and higher, when a certain rotating speed is reached, lift force can be generated, the vertical take-off effect of the aircraft is achieved, the structure is simple and compact, and the cost is low.

    本发明涉及飞行器技术领域,特指一种单层四旋翼飞行器,包括机架,机架上设有动力装置,机架的前端与后端分别设有飞行装置,飞行装置包括支撑杆、U形连杆以及设于U形连杆两端的飞行单元,支撑杆固定于机架上,U形连杆的中心铰接于支撑杆上,飞行单元包括舵机、转动轴承以及对称设于转动轴承两侧的旋翼,转动轴承通过舵机固定于U形连杆的端部上,动力装置连接于U形连杆,并可驱动U形连杆上下活动。通过动力装置驱动U形连杆上下活动,进而带动U形连杆两端的飞行单元上下活动,可使旋翼绕转动轴承作周向旋转动作,且转动速度会越来越快,当达到一定转速时,可产生升力,从而起到飞行器垂直起飞的效果,其结构简单且紧凑,成本低。
