Abstract
In this study, a methodology for the identification of uncertainty of supersonic wind tunnel testing is developed. Instead of conventional multi-tunnel testing, multi-position testing is performed across the characteristic net of supersonic flow. From the variations in aerodynamic coefficients in body axes, the uncertainty caused by flow quality is identified about models of interest. Then, after the consideration of practically independent parameters, uncertainties of aerodynamic coefficients in stability axes are combined. Their validities are confirmed by correlation results of tunnel-to-tunnel comparison tests.
