An air-dropped underwater glider based on electromagnetic wings

Abstract

The invention discloses an air drop type underwater glider based on electromagnetic span wings. The air drop type underwater glider comprises a shell body, a signal device, a buoyancy force adjustingdevice, a barrel roll attitude adjusting device, a pitch attitude adjusting device and a control device, wherein the buoyancy force adjusting device, the barrel roll attitude adjusting device, the pitch attitude adjusting device and the control device are arranged in the shell body. The air drop type underwater glider further comprises a hang glider stretching device which comprises hang gliders,an electromagnet, a piston, a piston sliding rail, a first elastic element, a second elastic element and a locking mechanism. Under the elastic action of the first elastic element, the magnetic magnitude of the electromagnet is controlled by the control device to enable the piston to slide on the piston sliding rail to realize the location and release of the hang gliders, when the hang gliders arereleased by the electromagnet, and the elastic action of the second elastic element enables the hang gliders to rotate and spread winding a rotary shaft. The air drop type underwater glider based onthe electromagnetic span wings reduces the water-entry impact force of wings, is more suitable for air drop application, the wings are in put-away states before the air drop, occupied space is small,plane carrying is convenient to carry out, and the timeliness is higher.

Description

technical field [0001] The invention relates to the field of marine detection equipment, in particular to an air-drop underwater glider based on electromagnetic 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 ...

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 in the slap in the water; moreover, the stretched wings cause the underwater glider to It takes up a lot of space, and it also increases the difficulty of carrying and arranging the aircraft
