A variable geometry wingtip is comprised of two deformable yet relatively stiff airfoils (6, 7) that work in compression and tension against each other to change shape. There is only one moving part in the assembly (5) with no internal mechanisms to facilitate morphing. The wingtip (5) consists of a lower airfoil (7) and an upper airfoil. (6) The base of the lower airfoil (8) is mounted horizontally to an under surface (4) of an outboard end (2) of a wing. (1) The upper airfoil (6) has a portion (9) which is allowed to retract and extend from an upper surface (3) of the outboard end (2) of the wing. (1) A single projecting wingtip (11) is formed at an intersection (10) of the lower and upper airfoils. (6, 7)
