Flow field calibration of NUAA Φ0.5m hypersonic wind tunnel

Here presented in this paper are the calibration of flow field and force experiments of standard model AGARD-HB-2 carried out in NUAA Φ0.5m hypersonic wind tunnel at Mach number of 5,6,7 and 8.Calibration tests and standard model tests for nozzles at M5 and M8 are given in this paper.Diameters of the uniform field reach 336mm; maximum deviation of Mach number |Δma_j|_(max) is 0.006 at M5 and 0.007 at M8 respectively; standard deviation of Mach number σ_(Maj) is 0.378 at M5 and 0.484 at M8.All the parameters mentioned above meet the requirements of GJB4399-2002.Comparison of AGARD-HB-2 model force measurement data with domestic wind tunnels validated the accuracy of test data obtained by this facility.The flow field calibration and standard model tests indicate that this wind tunnel has met the design requirements.
