| 摘要: |
| 对高速水中兵器而言,水冲压发动机是最理想的动力推进装置,然而低速无法启动致使其难以广泛应用。为了解决水冲压发动机的低速启动问题,提出了微型涡轮机拖动微型混流泵的水冲压发动机增压进水系统构型方案,完善了微型涡轮机和微型混流泵设计方法,建立了涡轮机和混流泵工作性能仿真计算模型,通过数值仿真验证了设计结果的合理性,完成了涡轮机和混流泵的匹配设计,分析了增压进水系统的工作性能。结果表明:涡轮机及增压泵各项设计结果与目标值最大相对偏差小于3.2％,增压系统可将来流压力增加2.0 MPa,使得水冲压发动机的启动航速由90 m/s降低至63 m/s。研究成果对水冲压发动机技术的工程应用有参考价值。 |

| Abstract: |
| Water ramjet is the most ideal power propulsion device for high-speed underwater weapons. However, failure to start it at low-speed makes it hard for the engine to be widely used. In order to solve the problem of starting water ramjet at low-speed, a configuration scheme of water ramjet pressurized water intake system of the micro-turbine driving micro-mixed-flow pump is proposed. The design method of micro-turbine and micro-mixed-flow pump is perfected. And the simulation model of turbine and mixed-flow pump is established. The rationality of the design results was verified by numerical simulation. The matching design of the turbine and the mixed-flow pump is completed. And the working performance of the pressurized water inlet system is analyzed. The results show that the maximum relative deviation between the design results of the turbine and the pump and the target value is less than 3.2％, and the booster system can increase the fluid pressure by 2.0 MPa, reducing the starting speed of the ramjet from 90 to 63 m/s. The research results of this paper have reference value for the engineering application of water ramjet technology. |
