Aerodynamic structure, for a landing flap, an airfoil, an elevator unit or a rudder unit, with a changeable cambering

摘要: An aerodynamic structure (9) is provided for example a landing flap. The comprises an outer skin (11), which deformable in cross section longitudinal to air stream direction (12). (11) has ribs (1) with changeable cambering stiffening the stressed direction. comprise closed flexible external girdle (2). shape of (2) corresponds course (11). Furthermore, plurality struts (3) constant length, engage at both their ends.
