低温富燃火炬点火器研究

火炬式电点火器在国外氢氧发动机上得到了广泛应用，介绍了对低温富燃火炬点火技术的初步研究情况，初步设计的火炬点火器试验件实现可靠的低温点火，并具有较广的工况和混合比较化范围。

Study on Cryogenic Fuel-Rich Spark Igniter

Spark igniter is widely used in cryogenic liquid rocket engines in the world. A spark igniter has been successfully developed recently in China. The design and experimental research on the cryogenic fuel rich spark igniter are introduced in this paper. In the firing tests of the igniter, all the ignitions are successful without any misfire. Through these tests, the fundamental designs of the igniter are confirmed.
