Abstract
The invention relates to a wing unit, in particular a spar box for forming aerodynamically active surfaces of an aircraft, in particular airfoils, horizontal tail units, or rudder units of a plane. Aerodynamic improvements can be obtained due to a surface geometry of the aerodynamically active surfaces, which surface geometry is adapted to the respective operating state of the plane by using the actuating members and/or weight savings due to minimizing of structural mechanical loads of the wing unit.
Claims38
A wing unit, in particular a spar box, for forming an aerodynamically active surface of an aircraft, in particular airfoils, horizontal tail units, or rudder units of a plane, comprising:
- an upper shell and a lower shell, the upper shell and the lower shell forming the aerodynamically active surface;
- at least two ribs;
- at least two actuating members;
- and
- at least two spars;
- wherein in a region between the upper shell and the lower shell the at least two actuating members are arranged for modifying the surface geometry of the aerodynamically active surface or the mechanical properties of the wing unit, or both the surface geometry of the aerodynamically active surface and the mechanical properties of the wing unit;
- wherein between the at least two ribs, the at least two actuating members are arranged crosswise for forming a tension shear;
- and
- wherein the at least two actuating members are arranged substantially in parallel to the at least two spars.
