Embodiment

[0043] The present invention relates to a bionic underwater glider and its propulsion method. On the basis of a conventional underwater glider main body, a pair of gliding wings installed on the glider main body, a bionic tail fin at the tail, and a buoyancy changing device inside the glider main body are used to create a bionic underwater glider. Effective cooperation under different working modes to achieve mixed propulsion.

[0044] like Figure 1 ~ Figure 3As shown, the glider structure includes a buoyancy changing device 1, a tail fin 2, a first hang glider 3, and a second hang glider 4. Wherein the buoyancy changing device 1 changes the net buoyancy of the glider by changing the displacement volume, the tail fin 2 is installed at the tail of the glider, and can realize the function of swinging back and forth, and the first hang glider 3 and the second hang glider 4 are installed on the main body of the glider through a rotating pair. The hang glider rotating mechanism i...

Abstract

The invention discloses a bionic underwater glider, which comprises a glider main body, a buoyancy changing device, an empennage and a gliding wing; the buoyancy changing device is arranged on the glider main body, and changes the net buoyancy of the bionic underwater glider by changing the displacement volume; The tail fin is arranged on the tail of the glider main body through a tail fin swing mechanism to realize the back and forth swing function of the tail fin; Rotate function. Also disclosed is a bionic underwater glider propulsion method. The present invention can effectively cooperate in different working modes, so as to realize mixed propulsion and enhance the ability of diverse observation tasks. It has high propulsion efficiency, strong maneuverability, flexibility of bionic propulsion and high efficiency of gliding propulsion.

Description

technical field [0001] The invention relates to an underwater glider, in particular to a bionic underwater glider and a propulsion method thereof. Background technique [0002] Underwater glider is a special type of underwater autonomous vehicle (AUV). It does not have power devices such as propellers or propellers. It controls its own buoyancy changes through the variable buoyancy system inside the machine, and the positive Buoyancy and negative buoyancy translate into forward thrust, which propels the glider forward. It uses net buoyancy and attitude angle adjustment to obtain propulsion, and consumes very little energy. It only consumes a small amount of energy when adjusting net buoyancy and attitude angle, and has the characteristics of high efficiency and large endurance. But its high-efficiency feature is accompanied by its relatively fixed motion form and attitude. Underwater, it can only sail in zigzag and spiral orbits. The attitude of the fuselage cannot be in a ...
