用电弧加热空气,对带有突扩台阶后扩张形,入口M_a=2.1和3.0的超声速燃烧室进行了实验研究,并对两种不同燃烧室长度、煤油和氢气在垂直和平行喷射下的燃烧状况作了比较。
The air heated by electric arc was used to study the supersonic combustion chamber with expanding M (subscript a) = 2.1 and 3.0 after expansion step, and the combustion of two different combustion chamber lengths, kerosene and hydrogen under vertical and parallel injection The situation is compared.
