Performance estimation for differential pressurization pulse jet engine

摘要：

　　A differential pressurization pulse jet engine is suggested in this paper.Several realistic assumptions are made,physical model and mathematical model of the engines extrusion and filling process are built,and the mathematical model can be solved by setting some parameters.Working characteristics of the engine in each stage are analysed,and performance of the engine is estimated.Through suitably changing several structure parameters,analysing the performance parameters,the impacts of structural parameters on the engine performance are discussed.Finally,compared with conventional pulse jet engine,this engine provides an approach to pressurize and has a higher ratio.
