Couzinet 33
The Couzinet 33 Biarritz was a French long-range monoplane built by René Couzinet in the early 1930s.
Design
The Couzinet 33 was made of wood, with a thick cantilever wing with thickness of at the wing roots; with no dihedral on the upper surface. The wing main-spar was continuous from wing-tip to wing-tip; and the rear spars attached to the fuselage sides. The aircraft was covered with birch plywood, with the fuselage thinning to the rear, forming the characteristic tail of a René Couzinet signature aircraft.Couzinet designed the plane when he was 27 years old with only 28 flight hours.
