摘要:

针对影响催化点火的关键性因素，研究了一种简易可行的自激式催化点火装置。该装置采用具有高电阻的催化床，直接通电加热，从而大幅度降低来流混气的点火温度，降低点火能耗及缩短点火延迟期，可作为冲压发动机和涡喷发动机的辅助点火装置。

Abstract:

Presents a simple and useful self-sustained catalyst ignition device according to the keymotor effecting catalyst ignition. This device is applied with high-resistance as the catalyst-bed.Theignition temperature,the ignition energy and the ignition delay are reduced when the catalyst-bed iselectrically heated directly.As a supplementary ignition device of ramjets or turbojets this achievementin scientific research has a bright future.
