Flexible tail fin hybrid drive underwater glider

Abstract

The invention proposes a flexible tail fin hybrid drive underwater glider, which belongs to the technical field of underwater vehicles. space, and the swing amplitude and frequency of the flexible caudal fin can be accurately controlled. The flexible tail fin hybrid drive underwater glider includes a glider main body, a flexible tail fin driving device is installed at the tail of the glider main body, and the flexible tail fin driving device includes a flexible skin in the shape of a tail fin, and the flexible skin is installed on the tail end of the glider body through a tail fin connector , the flexible skin is provided with a tensioning assembly for driving the flexible skin to swing, and the tail of the glider main body is provided with a driving assembly for driving the tensioning assembly.

Description

technical field [0001] The invention belongs to the technical field of underwater vehicles, in particular to an underwater glider driven by a flexible tail fin hybrid. Background technique [0002] The underwater glider relies on the adjustment of buoyancy to achieve heave, cooperates with the lift of the horizontal wing to convert vertical motion into horizontal motion, and uses the built-in attitude adjustment mechanism to change the attitude to achieve gliding motion. It can perform long-term, large-scale observation and Detection plays an important role in the global ocean observation and detection system, and has the advantages of long voyage, long voyage time, and good concealment. [0003] Due to the low speed of the underwater glider itself, poor maneuverability and anti-current ability, a variety of hybrid drive underwater gliders have been developed, and the tail fin hybrid drive underwater glider is one of them. At present, most of tail-fin hybrid-driven underwat...

AI Technical Summary

Problems solved by technology

At present, most of tail-fin hybrid drive underwater gliders use rigid tail fins, such as the bionic underwater glider disclosed in patent CN106005323A, and a small number of flexible fins are installed behind the tail fin, such as the fishtail flapping wing hybrid underwater glider disclosed in patent CN104386228A , but even with the addition of flexible fins, the flexibility of the tail fin is still poor, which is not conducive to the long-term and large-scale operation of the underwater glider

[0004] In the field of bionic robotic fish, although many flexible tail fin structures have been proposed, the overall drive structure has the problem of large volume and complicated drive. The space other than the tail is not suitable for small and light underwater gliders
