摘要： The invention relates to a turbine wheel arrangement for a gas turbine comprising two successive turbine wheels (18, 20) rotating in opposite directions, wherein the first turbine wheel (18) comprises flow channels (42) of a Laval cross-sectional shape, distributed over the circumference and having radially inner gas inlets (43) and radially further out gas outlets (45), in each case with a substantially tangential flow direction component, wherein the gas outlets (45) act an the second axially or radially acting turbine wheel (20) in the direction of flow. This has the effect that the thermal energy and compressive energy of the gas at the nozzle inlet is largely converted into flow energy at the outlet of the turbine stage. The rotational speeds of the two rotors coupled to the turbine wheels can be set as desired, allowing the operational states of the two systems to be optimally set without adjusting systems.

摘要： The invention can be used for the pressurized storage of gases. The aim of the invention is to provide a pressurized container consisting of fibre-reinforced plastic with flat or practically flat lids. To achieve this, wound axially aligned reinforcement structures run through the interior of the body and absorb the major part of the required forces on their plane of alignment. The invention is characterized in that fibre strands are distributed uniformly over the cross-sectional surface of the cylindrical pressurized container, are aligned axially and fixed to flat or practically flat lids. In one advantageous embodiment of the invention, a container is formed by the spiral winding of an essentially unidirectional fibre-layer, which is thicker at its edges. Reinforcement layers, which are arranged in a circumferential direction and exert a radial action, cover the reinforcement strands or the spirally wound unidirectional fibre-layer, said layers forming the casing of the pressurized container.
