Visualization of Shock Wave around Hypersonic Diamond Cone by the First Electric discharge Method

Abstract

The shock shape around a slender diamond cone traveling at hypersonic speed was visualized by using the first electric discharge method. The visualized shock shape was compaired with the result obtained theoretically. Both the results agreed comparatively well. From this comparison, it was comformed that the first electric discharge method is useful for visualizing three dimensional shock shapes around hypersonic vehicles.
