- This paper presents a method for effcient creation of the aerodynamic database for the X-31 experimental aircraft, from low fidelity (Euler) and high fidelity (RANS) CFD. The challenge is to obtain good data for extreme flight conditions. A co-Kriging interpolation model for aerodynamic moments, forces and span loads is used, with an additional decision support system (DSS) using Proper Orthogonal Decomposition for data reduction.
