Abstract: A method for producing textile composite material preforms, particularly with or from one or more textile semi-finished products, includes compression molding a planar structure of one or more textile composite materials. The planar structure is cut laterally into textile composite material sections prior to compression molding and these cut textile composite material sections undergo compression molding individually or collectively and particularly with one or more other textile composite material sections such that as a result one or more textile composite material preforms are fully or partially formed.

Abstract: A method is provided for producing a fiber preform for a fiber composite component, in which method a fiber arrangement is provided on a support material and the support material is held, during a forming process, by a clamping device. The method provides at least one blank made of a fiber material; orients the blank according to the direction of loading of the blank in the fiber composite component by means of an automated manipulation device; fastens the blank to the support material; and provides the support material having the fastened blank for a subsequent process.

Abstract: A method and forming tool produce a multi-dimensionally profiled preform from a multidirectional fiber composite material. A tensioning frame envelops top and bottom tool components and fixes the fiber composite material so it is allowed to be subsequently fed-in under frictional engagement. In order to compensate for excess material in regions where a shaping gap has a weaker profile, the tool components have forming elements arranged in the edge trimming zone of the preform and defining between them a drawing-through gap for the material. The drawing-through gap becomes increasingly the shape of a bead in synchronism with the tool components closing movement, and/or the tensioning surface of the tensioning frame is vertically adjusted relative to a tool component inlet surface in the forming phase such that a drawing edge for the material is formed in the tensioning surface.

Abstract: A rotary storage heat exchanger structure for multi-shaft gas turbines, especially motor vehicle gas turbines. The same is arranged in a housing and is provided with one or more rotatable disc-shaped storage bodies having flow passages which extend substantially parallel to the axis of rotation of the storage body or bodies. There are hot exhaust gases and colder compressed working air passed through the passages. The storage body or each of the storage bodies is journaled in a housing web in an overhung position or is journaled at two bearing areas in a housing web or in a housing web and another structural part of the gas turbine. In spaced relationship to the storage body, nozzle gap means are provided on or in the housing in the extended plane separating the working air flow and exhaust gas flow play is provided between the storage body and the pertaining housing web and the inner working air and exhaust gas flow conducting devices.
