Airdrop type underwater glider based on water erosion separation extension wings

Abstract

The invention discloses an airdrop type underwater glider based on water erosion separation extension wings. The airdrop type underwater glider based on the water erosion separation extension wings comprises a shell, a signal device, a buoyancy regulating device, a roll attitude regulating device, a pitch attitude regulating device, a control device and a hang glider extension device, wherein thebuoyancy regulating device, the roll attitude regulating device, the pitch attitude regulating device and the control device are arranged in the shell. The hang glider extension device comprises hanggliders, a first elastic member, water-soluble fiber members and a locking mechanism for locking the hang gliders in the unfolding state. One ends of the hang gliders are fixed in the shell through rotating shafts, the other ends of the hang gliders are fixed outside the shell through the water-soluble fiber members, and the first elastic member is arranged between the hang gliders and the shell and can unfold the hang gliders through elastic force. According to the airdrop type underwater glider based on the water erosion separation extension wings, the entry impact force of wings is reduced,and the airdrop type underwater glider based on the water erosion separation extension wings is more suitable for the application of air-drop. Before air-drop, the wings are in the retracted state, less space is occupied, the airdrop type underwater glider can be conveniently carried on an airplane, and the timeliness is high; and at the same time, a wing extension mechanism does not need to provide additional power devices, the mechanism is simple, and the feasibility is high.

Description

technical field [0001] The invention relates to an underwater glider, in particular to an air-dropped underwater glider based on water erosion separation of wings. Background technique [0002] Underwater glider is a new type of marine exploration equipment. It realizes gliding motion with low energy consumption through net buoyancy and center of mass adjustment. It has the characteristics of high efficiency, strong endurance, and long detection time. Wide range of application requirements. Existing underwater gliders are generally carried by the mother ship for deployment. However, it takes a long time for the mother ship to reach the designated sea area, which restricts its application in emergencies, such as the black box search of the crashed aircraft, the detection of accidental natural phenomena, etc. . Therefore, improving the timeliness of underwater glider deployment and enabling single or multiple underwater gliders to reach designated sea areas quickly will expa...

AI Technical Summary

Problems solved by technology

When the underwater glider enters the water from the air, due to the large frontal area of ​​the stretched wings, it will bear a large hydrodynamic impact, and it is easy to be damaged ...
