Combined wing anti-flow underwater glider

Abstract

The invention belongs to the ocean environment monitoring and scouting technical field and particularly relates to an underwater glider. The technical scheme of the combination wing anti-stream-pattern underwater glider is that a front sealing cabin (25), a middle water seeping cabin (23) and a rear sealing cabin (19) are sequentially connected to form a stream-pattern structure. A pair of moving auxiliary wings (6) is installed outside a shell of the front sealing cabin (25), a pair of sweepback wings (8) is installed outside a middle axis horizontal plane of a shell of the middle water seeping cabin (23). The rear sealing cabin (19) is provided with a vertical tail fin (15). When a single fixed sweepback wing is utilized, the maximum horizontal speed of navigation is achieved, wherein the gliding angle is 35 degrees and the lift-drag ratio is 1.5. When the manner combining the fixed sweepback wings and the moving auxiliary wings is achieved, the target is to pursuit the farthest voyage and the gliding angle is 22 degrees and the lifting-drag ratio is 2.5. By changing the combination manner of the gliding wings and flexibly changing gliding parameters, better adaptability is provided for the underwater glider to perform different missions.

Description

technical field [0001] The invention belongs to the technical field of marine environment monitoring and reconnaissance, and in particular relates to an underwater glider. Background technique [0002] Underwater glider is a new type of underwater unmanned vehicle suitable for long-distance operation and long-lasting endurance developed in the 1990s. It is widely used in marine hydrological data detection and military applications. The underwater glider has the characteristics of easy to use, flexible, remote control, and reusable. It can realize both horizontal plane measurement and vertical plane measurement. It can effectively improve the space and time observation density of the marine environment when used for marine environment monitoring. At present, the United States has developed many types of underwater gliders. The common underwater gliders that can be driven by electric energy or temperature difference, such as Slocum, Spray, and Seaglider, have a maximum speed o...
