Abstract: A rotary-vane pumping machine has a core structure that includes a stator assembly defining a contoured surface of a stator cavity, a rotor spinning around a rotor shaft axis that is fixed relative to the stator cavity, and end plates disposed on either side of the rotor. The rotor has a plurality of radial vanes slots for housing a corresponding plurality of vanes that slide within the radial vane slot of the rotor. Each of the plurality of vanes has side walls, a tip portion, and a base portion, and the base portion has one or more tabs extending from at least one axial end of the vane. The plurality of vanes, stator cavity, and rotor define a plurality of chamber cells. The core structure is substantially made of low coefficient of thermal expansion Invar materials to achieve precise non-contact sealing clearances between components of the machine.

Abstract: This invention relates to a process for the manufacture of a blade/vane of a turbomachine, in particular a gas-turbine engine, said blade/vane consisting of a metallic enveloping structure and a supporting structure made of composite material provided inside of the enveloping structure and suitably joined to the enveloping structure. A metal-felt weave is welded or soldered/brazed to the sheet making up the enveloping structure, whereupon this sheet-weave-assembly is shaped by hydroforming or an internal high-pressure forming process to provide the enveloping structure of the blade/vane. Finally, the composite material making up the supporting structure is introduced into the cavity of the enveloping structure. When long-fiber reinforced composite material is used, a fiber-structure can first be placed into the enveloping structure of the blade/vane and the composite material may subsequently be introduced by high-pressure filtration, with the enveloping structure being preferably in a mold in which the said shaping by an internal high-pressure forming process takes place.

Abstract: A double wall hot gas path part for turbines, such as an airfoil, combustor, duct or shroud, comprises an outer skin and an inner support wall that are metallurgically bonded to one another. The double wall contains integral channels for passage of cooling air adjacent to the skin. The skin may be a metal alloy skin or a microlaminate structure, including microlaminate composite structures. Microlaminate composites typically have a lower density than that of the material used for the support wall, and a simplified internal geometry, which promote weight reductions in the parts and increases in engine operating efficiency.
