摘要
本文介绍了用差分干涉仪测量超声速流场中钝锥模型周围密度场的试验装置和测量结果,并同尖锥模型的测量结果进行了比较。
This paper describes the test apparatus and the resultsof measurement of gas density around a blunt conoid model using adifferential interferometer.The interferometer consists of a schlierenapparatus and a Wollaston prism.The test Was-conducted in a super-sonic wind tunnel with M=2.The results of measurement was comparedwith the gas density distribution around a sharp conoid model.
