    Abstract: A supersonic compressor rotor. The supersonic compressor rotor includes a substantially cylindrical disk body (56) that includes an upstream surface (68), a downstream surface (70), and a radially outer surface (66) that extends generally axially between the upstream surface (68) and the downstream surface. The disk body defines a centerline axis (62). A plurality of vanes (54) are coupled to the radially outer surface. Adjacent vanes form a pair and are oriented such that a flow channel (88) is defined between each pair of adjacent vanes. The flow channel extends generally axially between an inlet opening (90) and an outlet opening (92). At least one supersonic compression ramp (112) is positioned within the flow channel. The supersonic compression ramp is selectively positionable at a first position (156), at a second position (158), and at any position therebetween.

    Abstract: A counter-flow heat exchanger including a core region and a plenum region. The core region including a first set of heat exchanging passageways and a second set of heat exchanging passageways disposed at least partially therein. A plenum region is disposed adjacent opposed distal ends of the core region. Each of the plenum regions including a fluid inlet plenum, a fluid outlet plenum and a tube plate disposed therebetween. The first set of heat exchanging passageways is truncated and defines a first tube-side fluid flow path in a first direction. The second set of heat exchanging passageways defines a second tube-side fluid flow path in a second opposing direction. Each of the heat exchanging passageways extending from a fluid inlet plenum to a fluid outlet plenum. The tube plates and the core region include one of a cast metal formed thereabout each of the heat exchanging passageways or a braze bond formed between each of the heat exchanging passageways.

    Abstract: The present invention provides a supersonic compressor comprising a supersonic compressor rotor (100) comprising a dockable rotor disk allowing restriction or opening of portions of a fluid flow channel of the rotor in order to enhance performance of the rotor during different operational stages, for example rotor start-up or steady state. The supersonic compressor rotor (100) comprises a first rotor disk (101), a second rotor disk (102) and a third rotor disk (103) which share a common axis of rotation. The first and second rotor disks (101, 102) are rotatably coupled, and the third rotor disk (103) is disposed between them. The third rotor disk (103) is independently rotatable relative to said first and second disks (101, 102), and comprises a raised surface structure (110) for restricting or opening a portion of the flow channel defined by the rotor disks (101, 102, 103) and at least two vanes (150). The flow channel comprises a supersonic compression ramp (120) and encompasses the raised surface structure (110).

    Abstract: A regenerative closed loop thermodynamic power generation, cycle system is presented. The system includes a high-pressure expander to deliver an exhaust stream. A conduit is fluidly coupled to the high-pressure expander, which is configured to split the exhaust stream from the high-pressure expander into a first exhaust stream and a second exhaust stream. The system further includes a first low- pressure expander and a second tow-pressure expander. The first low-pressure expander is coupled to a pressurization device through a turbocompressor shaft, and fluidly coupled to receive the first exhaust stream. The second low-pressure expander is coupled to the high -pressure expander and an electrical generator through a turbogenerator shaft, and fluidly coupled to receive the second exhaust stream.
