ABSTRACT:
A telescopic airfoil comprising a plurality of short wing sections, each consisting of skin and rib, with tubular spar sections attached to the rib. Each spar section is adapted to telescope with respect to the next adjoining spar section toward the root end of the airfoil. Alternate spar sections are rotatable, and intermediate spar sections are held stationary, with the end portions of adjacent spar sections overlapping, and low-friction threads connecting the overlapping spar portions. The threads at opposite ends of each spar section are of opposite hand so that rotation of the rotatable spar sections causes the entire group to be drawn together into a housing at the root end of the wing. In this way, the wing span can be reduced to less than 30% of the full span, while during extension and retraction, the spars retain their full load-carrying capability.
