FX2B Fairing

The DPW 3 configuration is the same DLR-F6 geometry as used in the 2nd DPW Workshop with the addition of a wing-body fairing designed to alleviate the side-of-body separation on the wing.  The fairing is named FX2B:

CAD Models of DLR-F6 (without FX2B fairing)

Half Model Ref. Area = 72700 mm2
Mean Aerodynamic Chord = 141.2 mm
Moment Ref. = 504.9 mm (from fuselage nose)
Projected Half Span = 585.647 mm

CATIA:  F6-FEM_v2.model.gz

IGES:  f6_nac+clean_dpwII_v2.iges.gzf6_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.

CAD Models of DPW-W1 - Baseline Wing Alone

Ref. Area, S = 290322 mm2 = 450 in2
Ref. Chord, c = 197.556 mm = 7.778 in
Ref. Span, b = 1524 mm = 60 in

Moment Reference (updated 1/20/2006):
Fuselage Station (FS) -- 6847.145 mm = 279.475 in
Waterline (WL) ------------ 2226.615 mm = 90.882 in
Moment Reference Relative to the wing root leading edge:
x = 154.245 mm = 6.0726 in
z = 0.0 mm = 0.0 in
N.B. Please note that some grids may move the geometry, so verify the wing root leading edge location (e.g. the Boeing DPW-W1 grids have been translated so that the wing root leading edge is at the origin)

CAD Models of DPW-W2 - Wing Alone

Reference area, chord, and span are the same as DPW-W1 above
Moment Reference (updated 1/20/2006):
Fuselage Station (FS) ----- 154.245 mm = 6.0726 in
Waterline (WL) ---------------- 0.0 mm = 0.0 in
The DPW-W2 IGES geometry has the wing root leading edge at the origin, so the above is the correct moment reference.

N.B. Please note that some grids may move the geometry, so verify the wing root leading edge location (e.g. the Boeing DPW-W1 grids have been translated so that the wing root leading edge is at the origin)
