矢量泵喷推进器水动力性能

Hydrodynamic Performance of Vectorial Pump-jet Propulsor

传统水下航行器采用鳍舵装置控制航向和航速,舵的存在会降低推进器的进流品质,增强推进器的直发声,引起艇体产生结构振动。为解决该问题,设计一种全新的泵喷推进方式,在泵喷推进器的导管尾缘加装一段能调整和控制方向的尾喷管。基于STAR-CCM+软件进行数值计算,结果表明:该矢量泵喷推进器可产生较大的横向操纵力,可实现舵的操纵效果。

Conventional underwater vehicles use fin rudder devices to control the direction and speed,which lowers the inflow quality of propeller,increases direct sound of the propeller and causes structural vibration of hull.In order to solve this problem,a new propulsion method is designed by installing an adjustable and direction-controllable tail nozzle at the trailing edge of the pump propeller duct.The numerical calculation based on STAR-CCM+software demonstrates that the vectorial pump propeller can produce enough transverse controlling force and achieve the control performance of rudder.
