Abstract

A high efficiency wing for ultra light aircraft achieves its high lift/drag ratio for little increase in weight or costs. In addition, drag on landing can be increased to reduce the landing run. The shape is maintained by air pressure inside the wing, derived from forward speed and/or propeller slipstream. Initially, the air enters a scoop (4) beneath the leading edge member (1) and passes through a non-return flap (5), subsequently flowing out through a restricted opening (6) at the trailing edge. This gap is adjusted to achieve the desired profile, taking into account the porosity of the flexible covering (2). Another flap (8) in the upper surface can spill air from the profile, to increase drag, for example on landing.
