Abstract

Abstract

Bionic undersea vehicles with median and/or paired fin(MPF) propulsion modes have obvious application advantages in marine research, marine resource development, and military research owing to their excellent mobility and stability. The contour and motion equations of bionic ray undersea vehicles are established as a typical model of the MPF propulsion mode to analyze the influence of bionic parameters on the motion. The motion equation is written using Fluent UDF to realize dynamic fluid simulation of bionic rays, and the simulation results show that the bionic fin undulates to form a vortex that spins in opposite directions and constantly pulls back, providing forward thrust. This paper provides a technical reference for the design of bionic rays underwater vehicles.
