A lifting airfoil (10) includes a landing flap (20) movably connected to a main airfoil body (10') so as to form at least a portion of the trailing edge of the airfoil. The landing flap (20) includes a leading edge nose (21) and a trailing edge body (22), which are each bounded by an upper cover skin (23) and a lower cover skin (24). The trailing edge body (22) is connected to the leading edge (21) by the continuous upper cover skin (23), while a gap (25) interrupts the lower cover skin (24) between the leading edge nose (21) and the trailing edge body (...
[ What is claimed is:] [1.] A lifting airfoil comprising:an airfoil body having a forward edge and a rear edge,a flap movably connected to said airfoil body at said rear edge, wherein said flap comprises a flap leading edge nose and a flap trailing edge body, said flap trailing edge body is elastically flexible, said flap trailing edge body terminates along a flap trailing edge that forms a trailing edge of said airfoil, and said flap leading edge nose and said flap trailing edge body comprise and are bounded by a pressure-side cover skin and a vacuum-si...
