某航空发动机的加力燃烧室采用催化点火器点火。催化网管是点火器的关键部件。本文在网管表面状态对性能的影响方面进行了研究。试验证明 ,镀层表面的孔隙度对网管的性能有一定影响 ,但最主要的因素应是表面镀铂层的纯净性 Aeroengine afterburner combustion catalytic converter ignition. Catalytic network management is a key component of the lighter. This paper studies the influence of network surface condition on performance. Experiments show that the porosity of the coating surface has some influence on the performance of the network tube, but the most important factor should be the purity of the platinum layer
