Deformed geometries

The CAD models correspond to the NASA-CRM wing-body-horizontal tail.

The wing geometry accounts for the experimentally measured deformation.

Deformation informations

Deformation is considered only in the z-direction.

The deformation is averaged over 10 images (more info will be added).
