| Abstract: | The newly finished Φ200 hypersonic wind tunnel(Mach numbers2.5 to 7) has been tested and calibrated. The results of calibration indicating total temperature, total pressure, operating time of HWT-200 have accorded with the purpose of design. HWT-200 can run within large Mach number span at supersonic/hypersonic flow. The rms of Mach numbers (σ_M) at all test sections Math numbers from 2.5 to 7.0 reaches the requirement of GJB1179-91. A large, uniform region of flow was documented. Operational time of HWT-200 is no less than 20s. So, HWT-200 is a facilitv Which can be used for teaching of aerodynamic experiments and elementariy scientific researches. |
