2025FWEP on 26 track width (26E-BSL-4)
- 50mm (total) track width increase, with no FW profile extension



FW-01B
- Full CAD rebuild of FWEP
- Initially filling additional width of FWEP area with larger curl/footplate
- Instead of curl expanding inboard (as on 25E, want to stay straight, or expand outwards)

NOTES
- Much tighter bound core from vortex shed on footplate
- Vortex almost immediately blows up from bottom of endplate (inboard edge)
- Vortex from 1st diveplane doesnt interact well with 2nd set of elements
</aside>
FW-01C
- As FW-01B, but removes rear two vanes/diveplanes

NOTES
- Mostly as is, diveplane vortex blows up downstream - not as tightly bound as upper endplate
- Will reduce thickness of diveplane, to reduce to dropdown on outer edge

CHANGES
- Added flat footplate section from start, with reduced curl width to match 25E FWEP
- Tried to create sharp inboard shedding edge for helicity moving from curl onto footplate then under wing, rather than the sharp corner as previously. Reduced the Z height difference between the flat footplate section, and the outer edge of the curl, so further from ground, to reduce pressure gradient across
- Lowered diveplane, and increased chord to try and help put low pressure core above curl edge to reduce pressure gradient
