Hi Friends, our first entries, the Hi Max trainer and the Spitfire for advanced flyers. forgive the date on the Hi MaX. It should be 3/22/09. We shall be adding new pix as we progress. Our wings are styro but wrapped around with a one piece flexwood around the LE and TE. We are showing the Hi Max wings uncovered for you to appreciate this construction technique. The Spitfire wings are built the same way but covered with tape. The fuselage have 4 longerons of flexwood. Our models do not break easily since stress is on the flexwood and not on the styro and the foamboard used in the fuse. All our wings have upper and lower spars. Styros can be spray painted with acrylic paint after a coat of water based polyurethane. The Hi Max has a 38" WS and a 27" fuselength.
The spit has a 38 inch WS and 32 inch fuse. The wings have a slight dihedral.
History of the Spitfire:
In 1936 Reginald Mitchell created the Spitfire and made no shortcuts. He followed Physics to the letter and created the wing which followed the laminar flow of air when in flight. The result are the wings which are "all wingtips". The common problem encountered by designers was the vortex created at the wing tips where the high pressure from under the wing merges with the low pressure from the top. The solution was the elliptical wing tips. The Zero had almost fully sym wing tips. The P47 had a semi sym elliptical wing tips. But the Spitfire had the entire wings as a fully sym ellipse. It proved itself in air battles with the Fockewulf and the ME109. Adolf Galland, the German ace once asked Goering, the air marshall, "Give me a squadron of Spitfires". The Spit had 8 machine guns on its wings whose bullets all converged to a common point ahead. Never go in front of a Spitfire. The fuselage was slim. The aircraft not only performed extremely well but turned out to be a beauty as well. Most were fatique green but the ones in the Libyan dessert to fight Rommel were painted khaki brown.

The Germans called it the "Spitfaya".

ReplyDeleteThe Spitfire wings are not fully sym. |Rather, they are semi sym too with the LE a little bit more straigth.
