Recent Advances in Diver Propulsion Vehicle (DPV) Ganendra RI-1: Design, Analysis, Manufacture and Performance

A diver propulsion vehicle (DPV) Ganendra RI-1, also known as an underwater propulsion vehicle or underwater scooter is an item of equipment used by scuba divers and rebreather divers underwater to increase the range. DPV has done the final stages of Design, Analysis, Manufacturing and Performance Testing. The design has been completed to determine mechnical, electrical, and propulsion systems. Continued analysis of both structural analysis, and flow analysis that allows whether DPV is feasible to proceed in the next stage. Manufacturing has been done for RIB work that is by using 3-axis CNC machine. Performance of DPV has been done experiment, with thrust maximum up to 50 kgf, using 48 Volt and 80 Ah lithium-Fe battery, has been obtained maximum speed of DPV is 3.5 knots, endurance operational to 3 hours with operational depth up to 7 meters.
