Abstract

CFD-aided wind tunnel data corrections for static model deformation effect of NASA-Common Research Model (CRM) are performed for wind tunnel data obtained at the 2m×2m Transonic Wind Tunnel of JAXA (JTWT), the National Transonic Facility (NTF) and the European Transonic Wind tunnel (ETW). In this paper, the model deformation effects are estimated by difference between CFD results for a designed configuration and that for a deformed configuration. At first, the applied techniques for the model deformation correction are validated using two sets of wind tunnel data of the NTF at the Reynolds number of 20 million with different dynamic pressures. Then, the model deformation corrections are applied to the wind tunnel data obtained at the JTWT, the NTF and the ETW. It is shown that differences of the drag coefficients among the JTWT, the NTF and the ETW fall within about 10 drag counts by the model deformation corrections and the Reynolds number corrections for the JTWT data to align the Reynolds number at 5 million.
