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。 The law of regulation is very important for the design, operation and control of the ramjet engine. The ramjet works in a wide range of Mach number and large airspace. Due to various factors affecting the working status of the ramjet engine, it is more difficult to design the ramjet regulation rule of. Based on the similarity criterion of Mach number, this paper defines similar parameters to describe the similar working state of ramjet engine, and gives the design method of ramjet regulation law. The simulation results show that this method is effective and simple, and has a good Engineering application value.
