The invention provides a four-steering-engine control coaxial rotor system which comprises a rotor shaft, an upper rotor and a lower rotor, the upper rotor and the lower rotor are mounted on the rotor shaft, a gear box is arranged on the rotor shaft and located below the lower rotor, and the upper rotor and the lower rotor are arranged on the gear box. The rotor shaft is further provided with a first control mechanism and a second control mechanism, the first control mechanism is used for controlling the upper rotor to move to enable the aircraft to generate pitching motion, the second control mechanism is used for controlling the lower rotor to move to enable the aircraft to generate aileron motion, and the first control mechanism is located between the gearbox and the aircraft. The second operating mechanism is located between the gearbox and the lower rotor wing, and the first operating mechanism comprises an upper swash plate, a first steering engine set and an upper variable pitch pull rod. The aircraft has the advantages that the aircraft achieves the functions of rudder lifting, forward flying and left-right steering through cooperative control of the two steering engines, the rotor control functions are clear and do not interfere with one another, the rotor control efficiency is improved, the structural complexity is reduced, the overall reliability of the device is improved, and maintenance is easy.

    本发明提供了一种四舵机控制共轴旋翼系统,包括旋翼轴、安装于旋翼轴上的上旋翼和下旋翼,所述旋翼轴上设有齿轮箱,所述齿轮箱位于下旋翼下方,所述旋翼轴上还分别设有用于控制上旋翼运动使飞行器产生俯仰运动的第一操控机构和用于控制下旋翼运动使飞行器产生副翼运动的第二操纵机构,所述第一操纵机构位于齿轮箱与飞行器之间,所述第二操作机构位于齿轮箱与下旋翼之间,所述第一操纵机构包括上倾斜盘、第一舵机组和上变距拉杆。本发明具有使用两套舵机配合操纵使飞行器达到升降舵、前飞和左右转向的功能,旋翼操纵功能分明,互不干扰,提高了旋翼的操纵效率,减少了结构的复杂性,提高了装置的整体可靠性,且易于保养的效果。
