内容記述 | First the flow survey is made for the low-density hypersonic flow, which is achieved by a low-density operation of the gun tunnel (or free piston compression). In particular the measurements of flow velocity and, hence, of stagnation temperature are worked out by means of an explosion-wire technique and the flow survey done by traversing a free molecule calorimeter in the test flow region. With these diagnostics the characteristic feature of the test flow is investigated. It is found that, by a low-density operation of the present gun tunnel, the test flow of Mach number 10 and Reynolds number 650 (per cm) is achieved, which is applicable to experimental studies on low-density hypersonic flow problems.
