This is the airfoil of the famous Lazair ultralight. What is the name of this airfoil?
That looks close but I think there is too much camber in it as depicted above, and that is only the root airfoil. There are significant changes along the span.
I used to jokingly call it my 'Lie Back' airfoil because I usually design things at night in bed :)
At some point I hope to get a 3D CAD model published of the whole Lazair series of aircraft but I can't promise when.
The Lazair is to be featured on a Canadian stamp this year and there is a Lazair in the Smithsonian :)
PS. Peter Corley was killed in the Toucan of his own design and I never flew any aircraft with Peter hanging on my waist.
It's designer Dale Kramer's own home brew airfoil he developed mostly out of intuition and educated guessing. I don't know if he gave it a name. I visited their kit factory and nearly bought a Lazair in 1979.
