Development of Ray-Type Underwater Glider

Abstract

Underwater Glider is now the powerful tool for ocean sampling using torpedo shape. Inspired by the manta ray with their effective maneuverability, the ray-type underwater glider is developed with a dual buoyancy engine and a movable mass. The shape of this platform allows for larger payload of battery and sensors. The analysis of fluid resistance performance is carried out through Computational Fluid Dynamics (CFD) for the optimum shape. Simulation of gliding dynamics of ray-type glider is studied for understanding the advantage of what nature has already done for the shape of the manta ray.
