REFLECTOR: FW: Wing root fairings

[Hiroo Umeno]

Very interesting...  How much difference does eliminating these intersections make in reducing drag?

Taking it even further, how about fuselage-strake intersections?  Would flattening that out have any effect in reducing drag?  Think of much thicker, continuously curved baggage area (perhaps slanted, curved side rear windows)?  It would almost seem one could imagine an airframe where the roof and floor line transitions into wing-root without any sharp turns.  That would also increase the interior volume as well, right?

Or do such modification count against you since it reduces the effective "wing-shaped" strake area by extending the fuselage area out-ward?

(Maybe I am inhaling too much "experimental" gas)...

Has anyone done similar with the canard/doghouse and fuselage intersection? I have a removable doghouse and am pondering how to create a fillet and round out the angle without having a sharp edge- or is  a rounded edge better than nothing?

I don't. I'm trying to eliminate all 90 degree intersections. Here's a picture of my upper and lower wing-winglet intersections. I used pour foam to build up the area, then shaped it with sandpaper glued to a 6" PVC pipe, then covered it with two plies of bid.

Does anyone see any downside to fairing/filling the bottom wing-fuselage joint in an effort to reduce drag?
