Wing assemblies comprise a slat, wing support structures, and a gap-adjustment assembly configured to permit selective adjustment of the slat relative to the wing support structures. The gap-adjustment assembly comprises a track member and an adjustment member. The track member is pivotally coupled relative to the wing support structures about a track-member axis, the slat is operatively translationally coupled to the track member, and the track member is configured to constrain translation of the slat between a stowed position and a deployed position. The adjustment member is pivotally coupled relative to the wing support structures about an adjustment-member axis and pivotally coupled to the track member about a linkage axis. The adjustment member is configured to permit selective adjustment of a direct distance between the adjustment-member axis and the linkage axis.

Wing assemblies and aircraft with gap-adjustment assemblies for slats

Aircraft assemblies comprise an aerostructure, a sealing structure, and a flexure spring. The aerostructure comprises an end surface. The flexure spring is operably coupled between the aerostructure and the sealing structure and is configured to urge the sealing structure away from the end surface of the aerostructure. The flexure spring has a neutral configuration and a range of deflected configurations. The flexure spring is biased toward the neutral configuration.
