Abstract: An end effector for needling a fibrous preform includes a body (or head), a plurality of articulating presser feet mounted to the body and moveable with respect to the body, and a plurality of articulating needles mounted to the body and moveable with respect to the body. The needles may be configured to move between an extended position and a retracted position. The presser feet may be configured to move between an extended position and a retracted position. The end effector presser feet may conform to complex geometries of a fibrous preform. The end effector may control needling depth, needling density, applied tension and/or pressure on the fibrous preform, and needle angle.

Abstract: A manufacturing method is disclosed herein. The method includes arranging a preform over a surface of an inner mold line; folding the preform over sides of the inner mold line; pressing an end of the preform into a grip strip coupled to a side of the inner mold line; and applying pressure to the preform to force excess material of the preform into a forming bead of the inner mold line.

Abstract: An aft cascade ring includes a first ring portion having a first arc shape and defining a first portion first lug. The aft cascade ring further includes a second ring portion having a second arc shape and defining a second portion first lug, the second ring portion being coupled to the first ring portion such that the first portion first lug and the second portion first lug are aligned.

Abstract: An assembly is provided for an aircraft propulsion system. This assembly includes a fixed structure, a translating structure, a blocker door and a rigid linkage. The translating structure is configured to translate relative to the fixed structure. The blocker door extends between a blocker door first end and a blocker door second end. The translating structure is pivotally attached to the blocker door at the blocker door first end. The rigid linkage includes a first pivot attachment, a second pivot attachment and a third pivot attachment. The first pivot attachment is coupled to the fixed structure. The second pivot attachment is coupled to the translating structure. The third pivot attachment is coupled to the blocker door at the blocker door second end.
