Description

technical field [0001] The invention belongs to the technical field of aerospace testing, and is mainly aimed at a temporary gas analysis and sampling system based on component analysis. Background technique [0002] In the process of developing hypersonic propulsion, the ramjet engine has always been a focus of attention. After nearly half a century of continuous exploration, the combustion chamber is still one of the key technologies for the development of hypersonic propulsion. Its working process is complicated, and there are many factors that affect the evaluation of the comprehensive performance of the combustion chamber. The first problem that needs to be solved in laboratory research. Countries all over the world have paid extensive attention to the comprehensive performance of scramjet engines, and the combustion components are obtained through gas sampling. Therefore, how to accurately obtain combustion components has become the primary problem to be solved in eva...
