| Abstract: | The reliability of solid rocket motors (SRM) has become an important problem in motor designs. Designers have a hope to know the flow field in SRM in detail. Due to high temperature and high pressure of gas in SRM, direct measurement of the flow field is very difficult. Then the technic of the hydraulic analogy to flow field analysis of SRM has been developed. The hydraulic analogy can be applied qualitatively to the following types of compressible gas flow: rocket nozzle flow, subsonic and supersonic, steady and nonsteady, rocket nozzle exhaust plume, etc. In this paper, some fundamental theory of hydraulic analogy and schematic of water table are introduced. |
