## DLR-F6 Geometry

General Notes

The F6 configuration is NOT identical to the F4 configuration used in the 1st workshop.

F4 (wing-body only available):

- 4 airfoil sections define the wing ( 1st section: Ha5 airfoil, 2-4th section: R4 airfoil)

F6 (wing-body and wing-body-nacelle-pylon available):

- 4 airfoil sections define the wing (1st section: Ha5 airfoil, 2-4th section: R4/4 airfoil)
- translation of airfoil in vertical direction in kink area to make a smoother surface than for F4
- different twist distribution than for F4
- 3rd airfoil section at eta=0.84 instead of eta=0.7 (F4)

After releasing the geometry, inconsistencies were found in the fuselage curvature that have been resolved. The fuselage forward and aft closures and the pylon were also cleaned up. All geometry files downloaded after October, 2002 contain these revisions.

CAD Models

CATIA: F6-FEM_v2.model.gz

IGES: f6_nac+clean_dpwII_v2.iges.gz f6_farfield.iges.gz

> The iges file contains both the geometry with nacelle and without. To "produce" the igesfile for the clean configuration move the pylon- and nacelle panels and the lower inner wing panels (50,59,60) to invisible. Then move the "clean" inner wing panels 68 and 69 from invisible to visible. The reference data is the same as for the F4 as the wing planform and position and the fuselage have not changed.
