The invention discloses a jet-propelled attitude control device and attitude control method for a coaxial dual-rotor unmanned aerial vehicle, the attitude control device adopts turbofan jet-propelled structures which are arranged at the lower part of the coaxial unmanned aerial vehicle and are perpendicular to each other, and an airflow jet port and an air inlet are perpendicular to rotor shafts of the coaxial unmanned aerial vehicle; when attitude control is carried out, the rotating speed of a fan motor is controlled to control the air flow of an air jet port of a fan, the counter-acting force of jet air flow acts on the lower portion of the coaxial unmanned aerial vehicle, the coaxial unmanned aerial vehicle inclines by different angles, when the motor rotates forwards, the coaxial unmanned aerial vehicle inclines forwards and flies forwards, and when the motor rotates reversely, the coaxial unmanned aerial vehicle inclines backwards. And the unmanned aerial vehicle flies backwards, so that the flight attitude of the coaxial dual-rotor unmanned aerial vehicle is controlled. According to the jet attitude control mode, the flight attitude control of the coaxial dual-rotor unmanned aerial vehicle is more sensitive, the flight and hovering attitudes are more stable, the coaxial unmanned aerial vehicle is simpler in structure and lower in manufacturing cost due to the fact that a steering engine, a connecting rod and other mechanisms are omitted, and large-dip-angle high-speed stable flight of the coaxial unmanned aerial vehicle is achieved.
本发明公开了一种共轴双旋翼无人机的喷气式姿态控制装置及姿态控制方法,姿态控制装置采用置于共轴无人机下部的相互垂直的涡轮风扇喷气式结构,气流喷气口及进气口垂直于共轴无人机旋翼轴;本发明进行姿态控制时,通过控制风扇电机的转速,来控制风扇喷气口气流量的大小,喷气气流的反作用力作用于共轴无人机下部,使共轴无人机倾斜不同的角度,电机正转时,共轴无人机向前倾斜,向前飞行,电机反转时,共轴无人机向后倾斜,向后飞行,从而控制共轴双旋翼无人机的飞行姿态。本发明的喷气式姿态控制方式,使共轴双旋翼无人机的飞行姿态控制更加灵敏,飞行及悬停姿态更加稳定,由于取消了舵机,连杆等机构,使得共轴无人机结构更简单,制造成本更低,并且实现共轴无人机大倾角高速稳定飞行。
