基于相似参数的冲压发动机调节规律设计方法

调节规律对于冲压发动机设计,运行和控制都是十分重要的,冲压发动机工作在宽马赫数、大空域的范围内,由于冲压发动机工作状态受到多种因素影响,冲压发动机调节规律设计将是比较困难的。本文基于马赫数相似准则,定义了用以描述冲压发动机相似工作状态的相似参数,并给出了冲压发动机调节规律的设计方法,仿真结果表明了此方法是有效和简单化的,具有较好的工程应用价值。

Design method of regulating rule for ramjet engines based on similarity parameters

Regulating rule is very important for the design,operation and control of ramjet engines.Because ramjet engines work in a wide range of flight Mach numbers and height,the working states are influenced by several factors,making the design of regulating rule very difficult.Based on the Mach number similarity criterion,the similarity parameters are defined to describe the similar work states of ramjet engines,and the design method of regulating rule for ramjet engines is presented.Simulation results show that the method is simple and effective.
