Structure, in particular spar box, for forming aerodynamically active surfaces of air vehicles

摘要

The box has positioning units (11-14) arranged between an upper shell (2) and a lower shell (3). The positioning units change the surface geometry of an aerodynamic active surface and/or the mechanical characteristic of the box depending upon load conditions, using a control and regulating unit. The positioning units change the bending torsional coupling of the box depending on the load conditions.
