Liquid applicators and methods. The liquid applicators include a frame and an applicator head operably coupled to the frame and configured to support a section of an applicator fabric for operable application of a liquid to a substrate. The liquid applicators further include a fabric conveyance system that is operably coupled to the frame and includes a fabric pay-out assembly configured to supply the applicator fabric to the applicator head and a fabric take-up assembly configured to receive the applicator fabric from the applicator head. The liquid applicators further include a liquid delivery system configured to deliver the liquid to the section of the applicator fabric. The methods include delivering the liquid to the section of applicator fabric, engaging the section of applicator fabric with the substrate, and moving the section of the applicator fabric across the substrate to apply the liquid thereto.

Aircraft nacelles having adjustable chines are described. An example apparatus includes a multi-segment chine coupled to a nacelle. The multi-segment chine includes a first segment and a second segment. The first segment is oriented along a fore-aft direction. The first segment is rotatable relative to the nacelle about an axis of rotation. The axis of rotation is substantially perpendicular to a plane of the first segment defined by an outer mold line of the first segment. The second segment is fixedly coupled to the nacelle. The second segment is oriented along the fore-aft direction. The second segment is substantially coplanar with the first segment.

Aircraft nacelles having adjustable chines are described. An example apparatus includes a multi-segment chine having a first segment and a second segment. The first segment is fixedly coupled to a nacelle. The second segment is rotatable relative to the first segment about an axis of rotation. The axis of rotation is substantially perpendicular to a local area of an outer surface of the nacelle.

Aircraft nacelles having adjustable chines are described. An example apparatus includes a multi-segment chine coupled to a nacelle. The multi-segment chine includes a first segment and a second segment. The first segment is oriented along a fore-aft direction. The first segment is translatable relative to the nacelle along the fore-aft direction. The first segment includes one or more first airflow openings. The second segment is fixedly coupled to the nacelle. The second segment is oriented along the fore-aft direction. The second segment includes one or more second airflow openings. The second segment is substantially coplanar with the first segment. Translation of the first segment adjusts the transverse alignment of the first airflow openings with the second airflow openings to vary an allowable airflow through the multi-segment chine.

Krueger flap apparatus and methods incorporating a bullnose having a contour variation along a spanwise direction are described. An example apparatus includes a Krueger flap having a bullnose extending in a spanwise direction. The bullnose includes a contour variation formed by a plurality of protuberances located along the bullnose. Respective ones of the protuberances are spaced along the spanwise direction.

Example actuator assemblies to deploy aircraft leading edge flaps and seals for aircraft leading edge flaps are described herein. An example apparatus includes an aircraft flap that is movable between a stowed position and a deployed position. The flap includes a top panel. A notch is formed in the top panel and extends into a side of the top panel near a trailing edge of the flap. The example apparatus also includes a seal coupled to the flap. The seal is movable to cover the notch when the flap is in the deployed position.
