Research questionHow can aerodynamic surrogates trained on CFD be grounded in scarce wind-tunnel measurements without retraining?CFD-trained aerodynamic surrogates can reproduce numerical predictions while retaining systematic discrepancies from wind-tunnel observations. The practical difficulty is using limited experimental measurements to correct those discrepancies without discarding the surrogate’s existing capabilities.

Experimental grounding uses spatially registered pressure-sensitive paint measurements at Mach 0.70 and 0.85 over the same angle-of-attack range, with evaluation on held-out angles and surface-pressure distributions; the pretrained surrogate parameters are not modified.research paper · Sep 2, 2026
