在充分研究固体燃料涡轮机和高速轴流泵的基础上,提出了应用于水下航行器的喷水推进系统。研究了设计工况时,航行器、轴流泵、发动机的运动学和动力学平衡关系;在定深工况下,分析喷嘴数目变化时航行器的稳定速度;以及不同喷嘴数目时,航行器的变深和变速特性。研究结果表明,喷水推进器能够实现水下航行器大航深、高航速的性能目标。研究结果对喷水推进水下航行器具有重要的参考价值。

Waterjet propulsion system for underwater vehicle is presented based on fully discussion of solid fuel 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 larjze-deoth, and it provides an imoortant reference to waterjet propulsion underwater vehicle.
