Deformed geometries
The CAD models correspond to the NASA-CRM wing-body-horizontal tail.
The wing geometry accounts for the experimentally measured deformation.

NOTE: The original geometries have been smoothed and named with the "*_updatednose" suffix (credit: HeldenAero).
Deformation informations For each angle of attack, the deformation is averaged over 10 images. Each image was taken with two cameras using stereo pattern matching technique and 0.65sec exposure time. Since the main wing vibration time scale is much smaller than the camera exposure time, the wing vibrations cannot be detected and the measured deformation should be considered as an approximate mean deformation. *The above values are measured on the 2.16% model using JAXA wind tunnel test.
