The files below are for the NASA 2.7% scale full span and the NASA 5.2% scale semispan CRM-HL models. These geometries are based on the reference CRM-HL geometry with minor changes due to size constraints.
**Latest version of the 2.7% scale full span landing and takeoff CAD files were uploaded July 10, 2025**.
The file below (3001000_fullspan_configs) is a zip file that contains igs, step and x_t files for both the landing and takeoff configurations of the 2.7% scale NTF model.
***Please note: on the wind tunnel model, when the landing gear is removed, there is a cavity left in the underside of the wing.
