ABSTRACT:
An apparatus is provided for generating power, including modules connected in a closed loop. At least one module includes a duct. A motive fluid passes through the duct from the upstream side to the downstream side. An inlet fan is mounted in the duct at the upstream side for rotation about an axis. A motor or engine drives the inlet fan. A reaction turbine wheel is mounted in the duct downstream of the inlet fan on a rear shaft. The reaction turbine wheel has a plurality of pressure chambers disposed about the periphery of the reaction turbine wheel. The reaction turbine wheel is rotatable about the axis in a first direction, and the pressure chambers are curved from an upstream portion to a downstream portion in a second direction, opposite the first direction. An exhaust stator is mounted to the duct downstream of the reaction turbine wheel. An aft fan is mounted to the duct for rotation about the axis and is operably engaged to a rear axle. The rear axle is also attached to the reaction turbine wheel such that the aft fan rotates at a fixed speed with respect to the reaction turbine wheel. A power means is operably engaged to the reaction turbine wheel such that rotation of the reaction turbine wheel results in the generation of power.
