详细描述了 MOO = 10 时与具有平坦圆形底座的圆锥壁空腔相关的弓形冲击行为。对此配置进行了实验测试，并通过多种技术记录了冲击振荡频率和振幅以及冲击形状的测量结果，其中之一是在该测试期间首次使用激光干涉仪系统以非侵入方式确定弓形冲击振荡频率。主要行为是稳定的、周期性振荡的弓形激波。还讨论了测试期间一组条件下发生的剧烈弓形冲击不稳定性。
A detailed description of the bow-shock behavior associated with a conical-walled cavity with a flat circular base at MOO = 10 is presented. An experimental test was performed on this configuration, and measurements of shock-oscillation frequency and amplitude, as well as shock shape, were recorded by a number of techniques, one being a laser-interferometer system used for the first time during this test to determine bow-shock oscillation frequency in a nonintrusive manner. The primary behavior was a stable, periodically oscillating bow shock. Discussions are also made on a violent bow-shock instability that occurred for one set of conditions during the test.
