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: Wind turbine devices are presented that use counter rotating rotor assemblies in a horizontal axis wind turbine (HAWT) arrangement. This reduces the torque applied to the HAWT thereby reducing the structural requirements of a wind energy generation system. Additionally, the counter rotating rotor assemblies cooperatively rotate an output shaft. In one arrangement, this shaft is a vertical shaft which allows removing power generation equipment from the axis of rotation of a HAWT to a position below the wind turbine and/or located on the ground.
