An aircraft wing structure and a method for decreasing flight speed of the aircraft

摘要

The invention provides a wing structure for an aircraft, including a top skin (14) and a bottom skin (16) defining a primary wing surface, the surface having a width, a length, a leading edge (8) and a trailing edge (10); a flap (18) having a width smaller than the width of the wing surface and a length extending over a major portion of the wing length, the flap being hingedly joined adjacent to the trailing edge (10) of the wing, wherein the flap is capable of assuming two limit dispositions, a first disposition in which the flap extends substantially parallel to the bottom skin (16), and a second disposition extending towards the trailing edge (10) of the wing, at an obtuse angle. A method for slowing down the speed of flight of an aircraft is also provided.
