To estimate uncertainties in the JAXA 2m × 2m transonic wind Tunnel test data, we developed a new uncertainty estimation program and applied it for a wind tunnel test using the AGARD-B calibration model. This program computes uncertainties in aerodynamic coefficients by accumulating uncertainties in measurement data. Computing sensitivity coefficients, which indicate the impact of the uncertainties in the measurement data on the aerodynamic coefficients, is very complicated. This program automatically computes these sensitivity coefficients and evaluates the aerodynamic coefficient uncertainties. This program is implemented in the Digital/Analog Hybrid Wind Tunnel (DAHWIN) developed by JAXA and has been applied for wind tunnel tests since FY2013.
