摘要: Expansion tube has a theoretical potential to realize ultra-high-enthalpy flow for simulating acrothermodynamics of super-orbital entry flights capsule. However, since test gas stagnates at the secondary diaphragm rupturing diaphragm, an ideal is not obtained. The influence conditions on in expansion was examined through shadowgraph image framing interval ljs and pressure measurement. By using adequately-thin e.g. Mylar sheet 3im-thickness, as rupture process got close reflection shock wave could be reduced. Test speed about 7.5 km/s maintained 30Os = 3.5kPa that acceleration 16Pa.
