Abstract
A wing having a front section with a leading edge, a back section with a trailing edge, and a main body therebetween in which the back section and, optionally, the front section are movably connected to the main body to change a length of the chord line and a radius of the camber of the wing. The connections are configured such that a top surface of the front section, a bottom surface of the front section, a top surface of the back section, and a bottom surface of the back section can move, relative to the main body, in the fore and aft direction, simultaneously, sequentially, or alternatingly, and in any order to change the length L of the chord line and the radius of the camber.
