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.

利用直流电弧放电直接暴露在超音速气流中，进行了超音速气流中的点火和燃烧实验。电弧产生于安装在燃烧室壁中的两个电极之间，并被几种气体推出。研究表明，从有效性和实际应用的角度来看，在M=2.0附近的超音速空气流中点燃甲烷或甲烷/氢气混合气体，空气或氧气似乎比氩气、氮气或氦气更适合作为电极处供应的载气。
