The apparatus includes a support structure (204) coupled to the composite lay-up and a mold ring (402) coupled to the support structure. The mold ring includes a ring guide surface and a radial contact surface that is configured to couple to the composite lay-up. The apparatus further includes a mold plate (502) coupled to the mold ring. The mold plate includes a recessed surface and a plate guide surface, where the recessed surface is configured to couple to the composite lay-up and the plate guide surface is configured to couple to the ring guide surface. The apparatus also includes an autoclave (600) that applies pressure to the mold ring and the mold plate to move the plate guide surface along the ring guide surface to apply pressure to the composite lay-up.
Abstract:
A composite woven outlet guide vane (32) and method of forming are depicted. The guide vane (32) is formed by use of a preform structure (100) with a core (150) which is removed following the manufacture.
Abstract:
A fiber preform architecture and method of making, including a plurality of fiber bands (52). Each band of the plurality of fiber bands is placed at a time, at a predetermined position and orientation, to generate an interwoven and interlocking pattern between the fiber bands. Each of the plurality of fiber bands is formed of a plurality of fiber tows (50), positioned side by side at a predetermined spacing (x) to define one or more gaps between each tow in the fiber band and define a secondary based interleaving within each of the fiber bands. The plurality of fiber bands are interwoven in an in-plane and out-of-plane orientation by interleaving each of the plurality of fiber bands with one or more of the plurality of fiber bands previously laid down and not in a common plane. The plurality of fiber bands include three or more different orientation angles and provide uniformity in coverage.
Abstract:
A superconducting generator includes an annular armature connectable to rotate with a rotating component of a wind turbine. A stationary annular field winding is coaxial to the armature and separated by a gap from the armature. The field winding includes superconducting coils, and there is a non-rotating support for the field winding. The non- rotating support is a torque tube. The torque tube is a member formed of a composite material, or a member formed of a plurality of segmented sections, a space frame or strut torque carrying assembly. The torque tube is connected to a thermal shield casing or a field winding housing.
Abstract:
According to present embodiments or aspects thereof, a composite booster spool (31) with separable composite blades (50) is provided. The blades (50) are inserted radially from within the inner circumference of the spool (31) and extend outwardly through the spool. The system provides a reduced weight assembly as compared to prior art metallic or composite/metallic combination systems. Additionally, the blades are separable which results in a more field-serviceable assembly over a fully integral system wherein the blades and spool are integrally formed from composites or combination of metal and composites.
Abstract:
A wind turbine is presented. The wind turbine includes a rotor having a plurality of blades. The wind turbine further includes a shaft coupled to the rotor. Moreover, the wind turbine includes a superconducting generator coupled to the rotor via the shaft. The superconducting generator includes an armature configured to be rotated via the shaft. The superconducting generator further includes a stationary field disposed concentric to and radially outward from the armature.
Abstract:
The present technique provides a method for controlling an electron beam (e-beam) (62) in an X-ray tube (50). The method comprises emitting electrons from an electron source to form the e-beam (62), accelerating the e-beam from a cathode (56) through an aperture in a plate (92), focusing and steering (scanning) the e-beam from the aperture through a plurality of field generating plates (94), and accelerating the e-beam from the plurality of the field generating plates (94) to a target (52). Also provided are X-ray tubes and computed tomography systems.
Abstract:
A system and method for forming x-rays. One exemplary system includes a target and electron emission subsystem with a plurality of electron sources. Each of the plurality of electron sources is configured to generate a plurality of discrete spots on the target from which x-rays are emitted. Another exemplary system includes a target, an electron emission subsystem with a plurality of electron sources, each of which generates at least one of the plurality of spots on the target, and a transient beam protection subsystem for protecting the electron emission subsystem from transient beam currents, material emissions from the target, and electric field transients.
