    摘要: The difficulty and expense of fabricating a support strut for a ram air driven turbine are reduced by providing an axially opening channel in a central portion of the strut. Blockage of a portion of the airstream flowing through the ram air turbine and past the strut is reduced by extending the axially opening channel through the entire axial length of the strut. Apparatus for converting or transferring power generated by the ram air turbine to a point of use, such as an aircraft, is routed through the axially opening channel, thereby allowing convenient access to such apparatus. A strut design is provided which may be readily manufactured as a single unitary structure from a variety of metallic and non-metallic materials including fiber reinforced composites.

    摘要: A turbine blade (1), for example, for a ram air turbine engine, and method of making the turbine blade, wherein the turbine blade (1) includes a blade retention insert member (2) having a hub connector (3). The turbine blade (1) is fabricated by using sheet molding compound consisting essentially of discontinuous short fibers (7) initially random spaced within a polymer matrix sheet. A plurality of sheets of sheet molding compound are precut to a desired configuration or shape and placed in a heated blade mold. Heat and pressure are applied to the mold causing the sheet molding compound to flow around the blade retention insert member (2) and fill the mold cavity. The flow of the sheet molding compound causes the initially randomly oriented short fibers (7) to preferentially align in the direction of flow to rigidify the turbine blade (1). Fiber woven cloth skins (8) may integrally molded with the sheet molding compound during the compression molding process to accommodate high loads, and an aluminum chopped strand veil cloth (9) may also be integrally molded into the blade (1) or layers of conductive material may be deposited on at least portions of the surface of the turbine blade (1) during a secondary operation. At least one woven cloth material (6) may also be integrally molded into the turbine blade (1) to react to bending loads and to provide additional load transfer capabilities.

    摘要: A method of making a dial table is provided. A foam layout is interposed between a base assembly and a top assembly to form a composite layout. The base assembly includes a first segmented carbon fiber layout therein and the top assembly includes a second segmented carbon fiber layout therein. A caul plate is then placed adjacent to the composite layout. The caul plate includes a plurality of caul plate apertures. A vacuum is thereafter generated proximate the composite layout. A resin is drawn through the plurality of caul plate apertures using the generated vacuum until the composite layout is infused with the resin. The caul plate is removed from adjacent the composite layout and the resin-infused composite layout is baked. Thus, the dial table is made.
