Hi,
Read your thread about the facetmobile; am familiar with the NASA study.
I'm working on a "morphing" facetmobile which uses air bladders to control its shape. Well, it flattens and then inflates to the normal shape. It is intended to operate in the water, and to slightly submerge (only a couple of feet) for rough water survivability (think Golden Gate on a very rough day.)
The flight envelope that I intend is less than 10' above water's surface.
While the test models that I have made flew ok, I suspect my geometry was off. I've got a EULA kit arriving which is laser cut to test that theory, although your description seemed to describe same problems.
Would you share your design modifications with me?
Thanks for considering it.
Cheers!
