New Prototypes nearly done
« on: January 02, 2020, 09:35:22 AM »
OK, start laughing, but here are two pictures of the prototype "European Style" profile Carrier ships.The lousy looking covering really isn't that poor, I just reflects the dormant "trumpeter Vines hanging over the table of our gazebo. Questions? The wing is held on and is removeable to try another type.

Hey, I like the idea.  If we don't try it, how do we know if it works or not. D>K

I assume this is a NWS 40 device?

Paul, not engraved in stone as yet. The whole project is to see if several  new ideas an be put to work. I these two prototypes show promise then I will build something like the attachment for entry in a contest if I ever get up enough energy to ever fly competitively again.

I gave up on flat-bottom lifting airfoils. 

Flat bottom airfoils let you fly slow, but make it harder to hang.

Symmetrical airfoils can be stalled-out easier and are thus better able to hang.

Paul, Have you tried a flat bottom airfoil without the bottom  of the wing being covered? This approach is doing well in GB.
