The invention discloses a cross-medium bionic unmanned aerial vehicle based on thrust differential motion and array type piezoelectric propulsion and a working method thereof. The cross-medium bionic unmanned aerial vehicle comprises a flying fish imitating fuselage, a self-locking folding flapping wing system, array type piezoelectric propellers and a thrust differential motion control system. During underwater navigation, propulsive force is obtained through the array type piezoelectric propellers, and the flapping wings are contracted to the belly through the folding self-locking devices so as to reduce resistance. When the direction needs to be changed, deflection torque is provided through the differential control technology, and therefore the underwater movement posture is changed. When encountering an obstacle in the advancing direction, differential control enables the pelvic fins of the aircraft body to deflect upwards, the aircraft head faces the water surface, the array type piezoelectric propellers jump out of the water surface after being accelerated to a certain speed, and the folded flapping wings are unfolded to glide and advance in the air. According to the bionic cross-medium unmanned aerial vehicle capable of silently submerging, through the array type piezoelectric propellers and the self-locking folding flapping wings, the unmanned flying fish is endowed with the air flying capacity and the underwater submerging capacity, the application range of the unmanned flying fish is widened, and the survivability of the underwater vehicle is improved.

    本发明公开基于推力差动和阵列式压电推进跨介质仿生无人机及其工作方法,包括:仿飞鱼机身、自锁折叠扑翼系统、阵列式压电推进器、推力差动控制系统。水下航行时通过阵列式压电推进器获得推进力,扑翼通过折叠自锁装置收缩于机腹以减小阻力。需要改变方向时,通过差动控制技术提供偏转力矩,从而改变在水下的运动姿态。在前进方向遇到障碍物时差动控制使机身腹鳍向上偏转,使机头朝向水面,阵列式压电推进器加速到一定速度后跃出水面,将折叠的扑翼展开在空中滑翔前进。该装置可以静默潜航的仿生跨介质无人飞行器,通过阵列式压电推进器和自锁折叠扑翼,赋予无人飞鱼空中飞行和水下潜航的能力,扩宽了无人飞鱼应用范围,提高其潜航器的生存能力。
