Abstract: Compression mold assembly for forming a preform of a cascade includes first and second die elements and an axis of alignment. Line of removal of a formed preform is positioned perpendicular to a plane perpendicular to the axis of alignment. First die portion includes first curved surface forming interior surface of first strong back and second die portion includes first curved surface forming interior surface of a second strong back of a cell of a formed preform. Second die portion includes second curved surface forming an interior surface of a first vane on forward side of the cell of the formed preform and first die portion further includes first wall member which extends along line of removal and a second wall member which extends angularly from first wall portion forming an interior surface of a second vane positioned on an aft side of the cell.

Abstract: A section divider assembly is configured to be positioned above one or more seats and indicate a boundary of a section onboard a cabin of a vehicle. The section divider assembly includes an attachment header, and a barrier extending downwardly from the attachment header. A first coupler is secured to the attachment header. The first coupler is configured to be removably secured to a first fitting secured to a strongback of a stowage bin assembly within the cabin. A second coupler is secured to the attachment header and spaced apart from the first coupler. The second coupler is configured to be removably secured to a second fitting secured to a fixed rail within the cabin.

Abstract: A mold insert assembly includes a base section having a base side removably attachable to a base plate of a mold and a first interface surface having a notched portion thereon. A first section includes a first interface side with a first interconnecting tab sized to engage the notched portion of the base section when the first interface side abuts the first interface surface, the first section further including an adjoining side having an interconnecting notch. A second section includes a second interface side having a second interconnecting tab, where the second interconnecting tab is sized to engage the interconnecting notch of the first section when the second interface side abuts the adjoining side, and where the base section, the first section, and the second section when assembled form a contoured insert configured to create a contoured cavity in a part formed within the mold.

Abstract: Methods of fabricating a component, such as a cascade grid panel for a jet engine thrust reverser, having a plurality of cavities extending through the component, with each cavity having at least one surface with a complex contour, and related devices. A plurality of two or more mold inserts are stacked to form a mold insert stack, with the mold insert stack having a plurality of mold bosses formed by mold boss sets. The mold boss sets are each formed by a mold boss segment from each of the mold inserts. Further, the mold boss segments are affixed to respective baseplates so that the mold boss segments can be handled as a group and remain properly positioned relative to their neighboring mold boss segments.

Abstract: A cascade assembly for a jet engine thrust reverser comprising an inflow cascade, an outflow cascade, and fasteners. The inflow cascade has a plurality of inflow vanes, a plurality of inflow strongbacks, and a front inflow flange. The outflow cascade has a plurality of outflow vanes, a plurality of outflow strongbacks, and a front outflow flange, wherein each of the plurality of outflow strongbacks are parallel to each other. The fasteners extend through the front inflow flange and the front outflow flange.
