Segmentized flap system
First Claim
1. A flap system for transonic aircraft wings which system includes flap segments arranged in span direction, a driving system for protraction and retraction of the flap segments, comprising:
- a plurality of spindle drives connected to said flap segments such that each flap segment is connected to at least two spindle drives; and
control means for controlling said spindle drives in such a manner that at least some of the drives are independently controlled from each other, such that those of the spindle drives that are connected to the same flap segment, are controlled independently from each other to obtain pivoting of that same flap segment on a vertical axis.

Abstract
A flap system along the trailing edge of a transonic aircraft wing which system includes segments arranged in span direction, a driving system for protraction and retraction of the segments includes a plurality of spindle drives connected to the segments such that each segment is connected to at least two spindle drives; are controlled the spindle drives in such a manner that at least some of the drives are independently controlled from each other so that the segments can pivot on vertical axes, in addition to a regular pivoting about respective horizontal axes.

5. A flap system for transonic aircraft wings which includes segments arranged in the span direction, and including means for protraction and retraction of the segments as well as pivoting on horizontal axes, the improvement of a plurality of independent means coupled to and acting on respective opposite ends of the segments for thereby pivoting the segments additionally about different vertical axes, independently from any protraction and retraction of any of the segments as a whole.
