Abstract: A manufacturing system includes a cutting machine, an adhesion machine, and a pick-and-place system. The cutting machine sequentially cuts a continuous length of a unidirectional prepreg into prepreg segments. Each prepreg segment has an opposing pair of segment cut edges that are non-parallel to a lengthwise direction of the unidirectional prepreg. The adhesion machine has a conveyor belt and an adhesion station. The pick-and-place system sequentially picks up the prepreg segments from the cutting machine, and places the prepreg segments in end-to-end relation on the conveyor belt, and in an orientation such that the segment cut edges are generally parallel to a lengthwise direction of the conveyor belt. The conveyor belt feeds the prepreg segments to the adhesion station. The adhesion station adheres the prepreg segments to a continuous length of a backing material, thereby resulting in a continuous length of a backed cross-ply prepreg.

Abstract: A method of manufacturing a panel assembly includes supporting the panel assembly in a free state using a holding fixture. The panel assembly has a skin panel, and sacrificial material coupled to a skin panel inner surface. The method includes acquiring a free state outer surface contour of the panel assembly by scanning a skin panel outer surface while the panel assembly is supported by the holding fixture. The method also includes developing a numerically controlled (NC) machining program having cutter paths configured for machining the interface locations to an inner surface contour that reflects nominal thicknesses of the panel assembly based off of the free state outer surface contour. In addition, the method includes machining the sacrificial material at the interface locations by moving a cutter along the cutter paths while the panel assembly is supported by the holding fixture.

The conveyor belt feeds the prepreg segments to the adhesion station. The adhesion station adheres the prepreg segments to a continuous length of a backing material, thereby resulting in a continuous length of a backed cross-ply prepreg.

Abstract: A method of manufacturing a backed cross-ply prepreg comprises cutting, using a cutting machine, a first continuous length of a unidirectional prepreg into first prepreg segments, each having an opposing pair of segment cut edges that are non-parallel to a lengthwise direction of the unidirectional prepreg. The method also includes picking up, using a pick-and-place system, the first prepreg segments off of the cutting machine, and placing the first prepreg segments in end-to-end relation onto a conveyor belt of an adhesion machine, and in an orientation such that the segment cut edges are generally parallel to a lengthwise direction of the conveyor belt. The method also includes feeding, using the conveyor belt, the first prepreg segments to an adhesion station of the adhesion machine, and adhering, using the adhesion station, the first prepreg segments to a continuous length of a backing material.

Abstract: An actuation mechanism, a flap mechanism, and an aircraft. The actuation mechanism includes drive links and drive mechanisms connected to opposite ends of the flap that move the flap to various positions. The drive mechanisms are actuated by torque tubes connected to a drive motor via a differential. The differential distributes torque to the torque tubes. In the event of abnormal operation of one of the drive links or drive mechanisms, the differential limits torque to the remaining drive link and drive mechanism such that the flap does not deploy or retract in a skewed manner.
