This is a flying wing aircraft I designed recently, and is copyright (C) 1999 by Nick Porcino.

The wing has no twist currently, as I'm exploring the implications of the "whale fin" tips. I think that they delay the onset of wingtip vortices to the very tips of the "fins", and that they might help eliminate Dutch roll and tip stalls by delaying the onset of separation at the tips at high angles of attack. Twist contributes to the delay of tip stall, and I wanted a clear indication of the effects of the tip.

The construction marks on the diagram below indicate Golden Mean proportions, chosen mostly for aesthetic appeal.

I've built a small hand-toss glider which glides straight provided there's a little upwards deflection of the central control surface.

You may do whatever you like with this design, provided you credit me with the wingtip idea, and if you want to produce a model of it for sale, I want a piece of the action!

An unusual project aircraft from the mid twentieth century.
