摘要： A fillet for a composite panel may be formed by pulling a prepreg slit tape from a spool and winding the slit tape into a fillet mold around the perimeter of a wheel. The tension, heat, and speed may all be adjusted during the winding process. A guide may guide the slit tape to specific locations in the fillet mold. The fillet may be removed from the wheel and coupled to the composite panel and cured.

摘要： A panel for attenuating noise includes a porous first skin, a second skin, and a core (26) connected between the porous first skin and the second skin. The core (26) includes a corrugated body (42) and a stringer body (44). The corrugated body (42) includes a plurality of corrugations (48) configured from at least a plurality of baffles (52) and a plurality of porous septums (53). Each of the corrugations (48) includes a respective one of the baffles (52) and a respective one of the porous septums (53). A first of the corrugations (48) forms a first channel (76) that extends laterally between and longitudinally along a first of the baffles (52) and a first of the porous septums (53). The stringer body (44) includes a plurality of sidewalls (80) arranged longitudinally along the first channel (76). Each of the sidewalls (80) is disposed within the first channel (76) and configured to fluidly isolate longitudinally adjacent portions of the first channel (76) from one another.

摘要： A guide system for translating components of an aircraft engine nacelle includes a track assembly (106) and a slider assembly (150). The track assembly includes a track guide member (108) and a track liner (112) engaged therewith. The track guide member includes a track channel (109) configured to receive the track liner. The track liner defines an interior surface and includes a projection portion (120) projecting inwardly of the track channel to define a convex surface. The slider assembly translatably engages the track assembly and includes a slider member having a head portion (154) configured to be received within the track channel. The head portion defines a concave surface substantially corresponding to the convex surface of the track liner and is configured to mate therewith. The slider member further includes an extension portion (156) extending from the head portion and outwardly of the track assembly.

摘要： A method may include placing a dry fabric over a tool; pressing a first resin film over the dry fabric while the dry fabric is draped over the tool to create an outer layer of the laminate composite structural component; repeating the placing and pressing process until a desired thickness of the outer layer is achieved; compressing a second resin film and a dry fiber fabric between two rollers to tack the second resin film to the dry fiber fabric to create a resin-fabric sheet comprising a resin film layer and an dry fiber fabric layer; cutting the resin-fabric sheet to a pre-determined shape to create at least one resin-fabric preform; and draping a first resin-fabric preform over at least a portion of the outer layer, wherein one or more edges of the first resin-fabric preform overlap the outer layer to create an internal edge.

摘要： Assemblies are provided for an aircraft with a gas turbine engine (12). One assembly includes a body (18) such as an inlet nose lip (18) of a nacelle (14) for the gas turbine engine (12). This assembly also includes a thermal management system (16) that includes a duct (58), a regulator (60) and a flow restrictor (62). The thermal management system (16) is configured to direct a flow of bleed gas through the duct (58) from the gas turbine engine (12) to the body (18) for substantially preventing ice buildup on the body (18). The regulator (60) is configured to affect the flow of bleed gas downstream of the regulator (60). The flow restrictor (62) is configured to selectively restrict the flow of bleed gas through the duct (58) when a temperature of the flow of bleed gas is greater than a threshold temperature (T threshold ).
