摘要
国内泵喷设计主要有2种技术路线,一种是喷水推进泵的设计思路,另一种是导管桨的设计思路。本文从喷水推进理论出发,建立泵喷研究控制体和基本方程,分析了喷水推进与泵喷推进性能预报的异同,并结合工程实践给出了按国标试验程序获得的推进泵模型试验数据应用修正、尺度效应修正和其他差异性注意事项,形成了泵喷推进性能预报方法。通过具体案例分析,验证了方法的可行性与有效性,为泵喷性能预报和优化设计提供参考,对工程实践具有重要指导意义。
There are mainly two technical methods for the pumpjet design. One is based on the theory of waterjet propulsion, and the other is based on ducted propeller method. This paper established pumpjet control volume theory and the basic equations of pumpjet propulsion, the similarities and distinction between the performance prediction methed based on pumpjet propulsion and waterjet propulsion is analyzed in this paper. The correction coefficient have been researched in combination with the practical parameters. The feasibility and effectiveness of the method are verified through the specific case analysis. It provides reference for the performance prediction and optimization of pumpjet.
