| Abstract: | 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. |
