Abstract: A method for generating a computer model of a composite component includes generating a surface mesh based on a ply drop region and a ply curved surface and generating node data including a plurality of node points relative to the ply drop region. The method also includes receiving composite data relating to a plurality of composite plies and generating a three dimensional model based on the composite data. The method further includes receiving layup table information and applying the node data, based on the layup table information, to generate a curve through a center of the surface mesh to define a plurality of element sets. The method also includes receiving composite draping data and determining, based on the draping data, where each element set intersects the three dimensional model. The method also includes analyzing an angle deviation of the plies based on the intersection of the element sets.

Abstract: A containment structure comprising an annular structure configured to provide close tolerance to a rotation structure. The containment structure includes a first abradable structure, a second abradable structure, and a shroud that is defined in part by the first abradable structure and in part by the second abradable structure. An annular surface of the shroud is defined by the first abradable structure and by the second abradable structure. The first abradable structure is harder than the second abradable structure.

Abstract: A blade member includes a leading edge, a trailing edge, and a blade body extending therebetween. The blade member also includes a dovetail, a transition region, and a transition relief. The dovetail includes a dovetail chord line extending between an axially forward face of the dovetail and an axially aft face of the dovetail. The dovetail chord line has a dovetail chord length. The transition region is formed between the blade body and the dovetail. The blade body and the transition region form a blade body transition chord line at the interface of the blade body and the transition region which has a blade body transition chord length. The transition relief includes a geometric relief in at least one of a forward and an aft end of the transition region and the dovetail. The dovetail chord length is less than the blade body transition chord length.

Abstract: A marine propeller composite blade an axially extending composite blade root including a dovetail wound in a partial spiral or helix around a centerline. Dovetail tapering down in width between clockwise and counter-clockwise dovetail sides of dovetail from dovetail bottom in a radially outwardly direction away from centerline. Marine propeller may include composite blade roots mounted in axially extending hub slots in a metallic hub, axially extending wedges disposed within the hub slots circumferentially between the blade roots and one of clockwise slot sides and counter-clockwise slot sides, and the wedges abutting the blade roots and the one of clockwise slot sides and counter-clockwise slot sides. Wedges and hub slots wound in a partial spiral or helix around a centerline. Radial retention means for radially retaining wedges in hub slots may include bolts engaging wedges and screwed into threaded holes in hub.

Abstract: An automated fiber placement (AFP) system includes a tool head with a compaction roller and a first variable heat source. The compaction roller is configured to receive at least one of a fiber and a plurality of fibers formed as a laydown tape, and is controlled to apply the laydown tape to a workpiece at a predetermined speed and direction. The first variable heat source is configured to apply a first amount of heat to the laydown tape. The first amount of heat applied is related to the predetermined speed. The AFP system further includes a second variable heat source configured to apply a second amount of heat to the workpiece. The second amount of heat applied is related to at least one of: a position on the workpiece, a thickness of the workpiece at that position, and a separation distance between the second variable heat source and the workpiece.

Abstract: A hybrid metal and composite spool includes metal rings on an outer diameter of a composite spool shell. Metal rings may include features such as annular or axial dovetail slots. Adhesive layers may be between the metal rings and composite shell which may be connected by a shrink bonded joint. The metal rings may include a single seal tooth ring with an annular radially extending seal tooth. A method for fabricating the spool may include fabricating one or more metal rings with the features therein, positioning the metal rings in place on an outer surface of an uncured composite spool shell of the spool before curing the shell, and curing the shell with the one or more metal rings positioned in place. Alternatively, rings may be heated to a temperature at least sufficient to slide rings over a cured composite shell, and allowed to cool and shrink onto shell.
