Abstract: A power generating unit includes a gas turbine with an air intake section, a compressor and at least one combustor and at least one turbine The power generating unit further includes a gas-cooled generator, being driven by the gas turbine and having a generator cooling system including at least one cooler, through which cooling water flows, and which removes heat from the generator. A more flexible operation of the unit can be achieved by connecting the generator cooling system to an air intake heat exchanger arranged within the air intake section of the gas turbine in order to transfer heat from the cooling water flowing through the generator cooling system, to the air flowing through the air intake section.

Abstract: In a heat shield (1), in particular for combustion chambers and for thermal fluid flow machines, the heat shield consists of a feltlike material (3) composed of compressed and sintered intermetallic fibers. Advantageously, the intermetallic fibers consist of an iron based or nickel based intermetallic phase.

Abstract: In a method for visualizing and processing a value assembly process, the value assembly process is visualized as a set of value assembly lines (VAL) arranged on different hierarchy levels. Each value assembly line receives value packages via input interfaces and consolidates these to form a value added package (VAP), an added value being created, and makes the added value package available at an output interface. The added value package can be used by a value assembly line of a higher-order hierarchy level as input value package. Likewise, the input value packages of the value assembly lines can be value added packages made available by lower-order value assembly lines, the lower-order value assembly lines being value assembly lines of a lower-order hierarchy level. All value assembly lines and all value packages have an identical structure; only the processed data differ from one another.
