ASW 15 1-5 from Hegi


I decided to test my Simulation skills and entered the information from the Hegi ASW 15 into FLZ-Vortex. I even managed to recreate the old Profile which came out ok I thought.
So if anyone has an old Hegi fuselage lying around I guess you can use the profiles attached to cut a new foam wing.

The fuselage sections could also make for a nice all epp model, all the sections are thick enough. From the videos I have found the original flew well, so let me know if anyone wants to build one, the design will fly !

oh, and an optimistic calculation.

Hi, nice work, but:
Hegi itself later came out with abachi-planked foam-wings for the ASW 15. (1979 I guess).
The old Eiffel 400 airfoil was often used in the 60's/70's but it's a little bit out of fashion today.
Good for floating at one speed, no range for going faster without wasting hight.

I did read about it being a bit of a floater (floating around in the sand dunes sounds perfect), and the videos I watched confirmed this.

I found that the Eiffel 400 top and the WB13535 matched the plan the best.
Following that allot of editing with modern tools, so I don't think it will be bad, very least less drag and hopefully more dynamic.

and a tp204 for comparison.
