Experiments of ignition and combustion in supersonic air flow field have been carried out by means of dc arc dischrges exposed directly in the flows. The arcs are produced between two electrodes mounted in the combustion chamber wall and pushed out by several kind of gases. The work showed that air or oxygen seemed to be more appropriate than argon, nitrogen or helium as the carrier gas supplied at the electrodes, from view points of effectiveness and practical use for the ignition of methane or methane/hydrogen mixture gas in supersonic air flows around M=2.0.

超音速空气流场中的点火和燃烧实验是通过直接暴露在流中暴露的DC弧形驱动器进行的。弧形在安装在燃烧室壁上的两个电极之间产生，并被几种气体推出。这项工作表明，从电极上提供的载气似乎比氩气，氮或氦气更合适，从有效性和实际使用的观点来点燃甲烷或甲烷/氢混合气体在M = 2.0附近的超音速空气流中的点火。
