摘要: |
介绍了新近建成的马赫数为2.5~7.0的Φ200mm高超声速风洞(Φ200 Hypersonic Wind Tunnel,HWT-200)调试情况及空风洞流场校测结果。调试校测结果表明,风洞的总温、总压、运行时间等参数完全达到了设计要求,顺利实现了宽马赫数范围下的超声速/高超声速运行;本风洞有较大的实验段流场均匀区,各流场的马赫数均方根偏差全部达到GJB(1179-91)的合格指标,一部分达到了先进指标。风洞运行时间不少于20s,是一座参数范围较宽、运行成本较低、维护方便、可用于空气动力学教学试验和基础性科学研究的设备。 |

Abstract: |
The newly finished Φ200 hypersonic wind tunnel(Mach numbers 2.5 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 (σM) at all test sections Mach 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 facility which can be used for teaching of aerodynamic experiments and elementary scientific researches. |
