Before the underwater glider is airdropped, the first rotary wing 21 and the second rotary wing 26 are in a tightened state under the constraint of the bundling structure 3, and the wing system 2 is tightened, so that the occupied space of the underwater glider is reduced. When the underwater glider enters water, the first fixed wings 24 and the second fixed wings 28 bear impact force, so that the rotating part structure is protected, particularly the first rotating shaft 22 and the second rotating shaft 27, the rotating part is prevented from directly bearing the impact force of the water entering and possibly causing the failure of the rotating structure to influence the unfolding of the wings, the wings adopted by the existing air-drop underwater glider are folded and folded on two sides of the main body, and the rotating parts of the wings directly impact the water surface.
