Abstract
A folding airfoil for an aircraft in which the wing or stabilizer airfoil n be folded and contained entirely within the fuselage of the aircraft. The airfoil comprises a series of elongated sheet metal channel sections of generally C-shaped cross section with the cross sectional dimension of successive channels decreasing so that each can nest entirely within an adjacent channel. The channels are each pivotally connected at the root end to the aircraft fuselage structure at spaced intervals along the chord line of the extended airfoil and the end sections of the channels are pivotally connected to each other such that the channels are pivotable between (1) an extended position extending spanwise of the extended airfoil to lie in tandem one behind the other, with adjacent channels partially overlapping and (2) a retracted or folded position in which the channels are nested within the leading edge channel section and lie along the chord line of the extended airfoil along the line of channel root end pivotal connections.
