Low Tech Concorde Wing Design
Hi Friends
While Í still finishing my Clement Ader Eole, recall a forgotten project...a Low Tech Concorde .
At first, let me tell you about a low tech XB 70 Cox 0.051 powered.
This plane was built in balsa, had a pusher Cox and its wing was simply a set of 1/8 pieces curved in a "S" shape to have something as a reflex airfoil.
It flew for all a year many times, until it was virtually sanded by the pavement on normal landings. The XB70 had not any kind of UC.
I live in a desertical area of Argentina...here green grass areas are not available.
Also hand launching the XB70 was really hard, and many of my buddies refused to launch that thing ! Many times was easier to find a pilot than a launcher. Obviously launching by myself was impossible if I was alone.
That XB70 make me think in a Concorde , using the same wing style and my new Norvel 0.074.
Concorde fuse may be build in foam, it is easier than in balsa, so fuse is not the problem.
BUT, last month found a pair of alfamodel (http://www.alfamodel.cz) retracts...and WOOOOOOOOOWWW! I need them in my Concorde , so no more problems with hand launching and landings.
But it´s impposible to put that retracts (They are 1/8 widht) on a 1/8 flat wing. So I need to made a normal D tube wing, very thiny to keep the speed up, but enough width to put inside the retracts.
BUT, what may be a reasonable airfoil for this plane...THAT´s the great question !!!
Comments ???
