[quote="marine air"]Hey ya'll,
I know this sounds kooky but what about wood spars for the F4U Corsair?
When I was a kid a local guy bought a kit to build a 1/2 scale W.A.R. Corsair replica. It had a spar with the distinctive gull shape cut from a single block of Spruce and it had the front and backs capped with aviation grade birch plywood glued and tacked on it.
The WAR replica may be 1/2 the size. But more importantly it is 1/10 the weight or less. Not a realistic alternative in this situation. As for carbon fiber. I think it would amount to more work in engineering and production than replicating the VOUGHT design. Even if you did it, then you would have a unproven design of mixed construction aluminum/carbon.Unless you plan to build the rest of the airplane from carbon fiber as well. BOEING even has trouble integrating the two materials, They have dissimilar coefficient of expansions with varying temperatures. I dont believe the corsair spar issue will be solved on a chat board, but in the shops of restorers and the wallets of those who pay people to solve the problems. I wish Mr.LANE and his associates much luck with the project. The CORSAIR world couldn't find a better leader for the project.
