A Hybrid Propulsion Method for Underwater Vehicle

Nowadays, Underwater Vehicles are widely used in ocean environment monitoring, ocean resources exploration and military areas. Therefore, it is required for Underwater Vehicles to have longer work time, wider work space, and what´s more, it is also required for Underwater Vehicles to have the ability to move agilely and locate accurately. Aiming at those problems, the paper proposes a new hybrid propulsion method for underwater vehicles. The hybrid propulsion which combines water jet propulsion, vector propulsion and glide propulsion, is the adaptive underwater propulsion that has long-time and low-exhaust work continuation, and can accommodate some emergency. The paper analyzes contrastively the motion performance in adaptive work conditions and prospects its applications at last.
