Working Characteristic Analysis of Waterjet Propulsion for Underwater Vehicles

Waterjet propulsion system for underwater vehicle is presented based on fully known of solid fule turbine and high-speed axial-flow pump. At the design condition, the equilibrium relation of kinematics and dynamics among vehicle, axial pump and engine is researched; At the fixed-depth condition, the velocity of underwater vehicle is changed by altering nozzle number; and the depth and speed character is also analyzed at different nozzle number. The research result indicates waterjet propulsion system can achieve the characteristic goal of high-speed and large-depth, and it provides an important reference to waterjet propulsion underwater vehicle.
