    Abstract: A containment structure configured to provide close tolerance for a rotation structure. The containment structure includes an annular inner casing having an inner annular surface being formed of an abradable material. The rotation structure is configured to be received within the annular inner casing such that the rotation structure is normally spaced-apart from the inner annular surface. The inner annular surface surrounds the rotation structure and has a first width. The rotation structure has a second width and the first width is greater than the second width. At least a section of the inner annular surface of the abradable material is cylindrical.

    Abstract: A computer-implemented method for generating a computer model of a composite component includes offsetting a projected ply curved surface outwardly along a base surface to define an offset ply curved surface. The method also includes defining a ply drop region of the base surface, the ply drop region includes another area of the base surface that is exterior to a ply curved surface and interior to an offset ply curved surface. A surface mesh is generated based on the ply drop region and the ply curved surface. The method includes generating a node data comprising a plurality of node points relative to the ply drop regions. Moreover, the method includes applying a curved function to the plurality of node points to facilitate forming a smoothed node data across the ply drop region. A ply mesh is generated using the smoothed node data and the surface mesh.

    Abstract: An apparatus for forming a flange on a component is presented. The apparatus includes a mold disposed for the placement of the component thereon, a forming tool, and a tubular bladder. The forming tool is assembled to hold the component with a first portion extending into a space defined between the mold and the forming tool. The tubular bladder has a non-uniform wall thickness around its cross section along a longitudinal dimension of the bladder. The bladder is disposed in a step defined in the mold, and configured to impart a forming force to the portion extending into the space to form the flange on the component when the bladder is inflated. A method for forming the flange on the component is also provided.
