The invention relates to a cross-medium unmanned aerial vehicle. The cross-medium unmanned aerial vehicle comprises a fuselage; a hydraulic system or a motor driving system is arranged in the machine body, and a planetary roller lead screw lifting system is further installed in the machine body. The wings are connected with the fuselage through wing connecting structures; a pod propeller; before entering water, the wings are controlled by a hydraulic system or a motor driving system to contract firstly and then retract into the fuselage at a variable sweepback angle; after the cross-medium unmanned aerial vehicle enters water, the pod propeller is controlled by the planetary roller screw lifting system to extend out of the fuselage, and the cross-medium unmanned aerial vehicle is controlled by the pod propeller to move underwater; when the unmanned aerial vehicle is ready to get out of water, the pod propellers are still kept under the water surface to provide power for the cross-medium unmanned aerial vehicle, and the wings are controlled through a hydraulic system or a motor driving system to be released from the fuselage from a variable-sweepback-angle state and then unfolded before lift-off; after the aircraft lifts off, the pod propeller is controlled by the planetary roller screw lifting system to be retracted into the aircraft body, and the resistance during flight is reduced.

    本发明涉及一种跨介质无人飞行器,其包括:机身;机身内设有液压系统或电机驱动系统,还安装有行星滚柱丝杠升降系统;机翼,通过机翼连接结构与机身连接;吊舱推进器;入水前,通过液压系统或电机驱动系统先控制机翼先收缩然后变后掠角收回机身中;入水后,通过行星滚柱丝杠升降系统控制吊舱推进器从机身中伸出,由吊舱推进器控制跨介质无人飞行器在水下的运动;准备出水时,保持吊舱推进器仍在水面下为跨介质无人飞行器提供动力,升空前通过液压系统或电机驱动系统先控制机翼由变后掠角状态从机身放出后再展开;升空后,通过行星滚柱丝杠升降系统控制吊舱推进器收入机身中,减小飞行时的阻力。
