Flexible undulating fin bionic submersible vehicle

Abstract

The invention belongs to the technical field of amphibious propellers, and particularly relates to a flexible undulating fin bionic submersible vehicle. A bionic undulating fin structure is adopted, undulating fins which are bionic from rays and deep sea hairtail are combined, high-elasticity silica gel is adopted as a material, high ductility is achieved, and the propelling system has the advantages of being excellent in maneuverability, low in hydrodynamic noise, easy in bionic transformation, high in terrain trafficability, capable of working in limited channels and other ocean operations. A mechanical structure of the bionic propeller adopts a steering engine-connecting rod-bionic undulating fin connecting mode, the side faces of steering engines are fixed to a thickness structure reserved on a main body part of the bionic propeller, the undulating fins can be controlled to swing through multiple steering engine swing amplitudes and steering drive, the functions of steering, acceleration, floating, sinking, braking and the like are achieved, and the bionic propeller can better adapt to the complex underwater environment.

Description

technical field [0001] The invention belongs to the technical field of amphibious thrusters, in particular to a bionic submersible with flexible fluctuating fins. Background technique [0002] Amphibious vehicles are currently a research hotspot because they can take into account both water navigation and landing driving. Traditional amphibious vehicles often integrate two sets of motion mechanisms in water and on land at the same time. The mechanical structure is complex, the control is difficult, and the stability is difficult to guarantee. This idea limits the further development of amphibious vehicles. [0003] In view of the above problems, a good solution is to use the principle of bionics to realize the integration of land and water propulsion devices. Through the study of hydrodynamics on the movement of aquatic organisms, a new idea of ​​propeller research is proposed. Bionic propulsion can be divided into two forms: swing and wave. Wave propulsion (pectoral fin o...
