Slat for extensible storage at leading edge of wing in aerofoil of aircraft e.g. commercial aircraft, has flexible outer layers that are adjoined on front structure, such that concave curvature is extended on underside of slat

摘要

The slat (1) has adjoining rear structure (3) attached to front edge (18) of the wing (19). A concave curvature (8) is formed on underside (9) of the slat. The deformation is occurred at main extension direction of the slat, without forming a gap in slat in main direction of extension of the slat with respect to front structure. The flexible outer layers (10,11) are adjoined on the front structure (2) in a state extended between front structure and trailing edge at bottom of slat, such that concave curvature is extended on the underside of the slat.
