Correcting a CFD-trained wing surrogate with wind-tunnel pressure paint
Paper title A Data Fusion Framework for Grounding Aerospace Surrogate Model via Experimental Wind-Tunnel Observations
Paper arXiv 2609.04267PDF
A GeoTransolver surrogate trained on 2,300 CFD runs of the NASA Common Research Model wing-body is frozen; a small correction head on its per-cell latents is trained on wind-tunnel pressure-sensitive paint, registered onto the CFD surface, to learn the gap between CFD and the measurements.
