Design and Simulation of the Biomimetic Flexible Fish Fin Propeller on Submarine

Abstract

Currently, there is an absence of underwater monitoring device in marine ranching area. the traditional submersible generally use screw propeller as its power equipment, but it lacked the rapid response, short turning radius and so on. Recently some bionic propulsion methods have emerged, which partly solved the problems above but still fail to meet the demanded properties. We used shape memory alloy combined with the design of robot fin to increase the flexibility, add the degree of freedom and higher the efficiency of the biomimetic flexible fish fin propeller.
