摘要： A preform for a composite article is manufactured by depositing reinforcing fibre (204) in a portion of the grooves (203) formed in sheets of foil (202) of the matrix material. Material (206, 208) compatible with the foil is disposed near the unfilled grooves and the foils are then stacked. When the preform is consolidated by pressure and temperature to form the composite, the compatible material fills the grooves which do not contain fibre, ensuring uniform debulking and avoiding lateral migration of the fibres or the formation of voids. The reinforcement may thus be distributed unevenly across the volume of the composite while identical groove patterns are used in all the foils. Non-reinforced areas may be readily machined. The compatible material may be a powder, wire or a sheet layed across the top of the unfilled grooves (203).

摘要： A method is disclosed for developing the contours of forming tools for fabricating metal members of complex shape such as wing skin and fuselage panels for aircraft. A computer simulation is performed of the age forming process on a geometrical representation of a member having the material properties of a desired metal member. The age forming process includes the steps of: a) overforming an unformed member in a tool having a contour of smaller curvature than the contour of the desired member; b) constraining the unformed member in the overformed condition; c) applying a thermal aging cycle to the member; d) cooling the constrained member following the thermal aging cycle; and e) releasing the constrained member from the condition imparted by step (b) and allowing it to spring back to a dimensionally stable condition which defines the desired member having a surface contour of complex shape. From the simulation, the contour of smaller curvature in step (a) to produce the desired metal member following step (e) is determined.

摘要： A method is disclosed for developing the contour of tools employed for forming aluminum alloy members exhibiting complex shapes. The members are precipitation, heat-treatable, aluminum alloys which are age formed. The resulting member is formed to the desired contour and, simultaneously, is heat treated to reduce residual stresses while improving its strength characteristics. The invention is particularly concerned with a new tool contour prediction method which is based upon the relationship, for a particular aluminum alloy, of the strain retained in a part after it has been subjected to an applied strain while constrained to a desired shape, then released after being heat treated in an autoclave or furnace.

摘要： A silicon-free metal powder mixture suitable for filling holes, slots and widegap joints in high temperature superal loys and/or for reforming damaged or missing surface extensions thereof, and capable of being processed at a temperature of about 2000°F. The semi-solid metal mixture has a sufficiently high surface tension and viscosity to be essentially non- flowing at the processing temperature so that it retains its applied shape and location without flowing during processing. The metal mixture after processing has a solidus temperature of at least 1950°F.

摘要： @ A combustor liner wall is provided with an interior wall, an exterior wall and a honeycomb structure disposed therebetween. The honeycomb structure is formed with generally radially aligned cells. The cells are constructed to define alternate array of gaps between the honeycomb structure and the interior and exterior walls, respectively. The cooling air thus undergoes repeated. undulations and mixing as it flows through the liner wall.

摘要： A beam such as a laser beam is used to weld two or more overlapping layers of metal together. The beam is generated by a generator (1), and applied through a tubular clamping element (2) which cooperates with a second tubular clamping element (3) to squeeze together the metal layers to be welded. By feeding an inert gas within the tubular elements (2, 3) via jets (15), an oxygen-free weld zone may be obtained. The beam is deflected to create a substantially spiral-shaped weld pattern. The beam generated may be moved under the control of a computer (6), or the workpiece and clamping members may be moved (Fig. 2 embodiment).
Improved weld strength over prior art resistance welding techniques is achieved, with a greater tolerance for differences in the relative thickness of the metal layers.

摘要： A centrifugal oil filter for removing contaminant particles from a pressurized fluid medium includes a cylindrical drum concentric with and fixedly secured to a rotational shaft, with an annular disc being disposed within and rotatable with the drum. The disc is centered within the drum and spaced from the internal circumferential surface of the drum so as to partition the drum into two radial passageways interconnected at said internal circumferential surface. The latter is of irregular configuration to define an annular collection zone for collecting contaminant particles centerfuged outwardly by rotation of said drum. Pressurized fluid medium is provided to one radial passageway, flows past the annular collection zone where the contaminant particles are centerfuged and entrapped in the irregular internal circumferential surface of the drum, after which the pressurized fluid medium is forced radially inwardly through the other radial passageway and out of the centrifugal oil filter.
