Abstract: A flywheel is provided in combination with a hybrid machine, wherein said flywheel comprises, in a radial direction, from inward to outward, an inner turbine, an intermediate compressor, and an outer array of magnets. The turbine cooperates with said hybrid machine to spin faster when said machine decelerates, and slower when said machine accelerates. An inner turbine drives both said intermediate compressor and said hybrid machine. The outer array of magnets is driven by said hybrid machine to accelerate the flywheel to accelerate the flywheel during braking of said hybrid machine. Said hybrid machine communicates with said flywheel to house it and render energy from it, in a hybrid manner such that energy is stored in a pressure or electrical storage mode, or both pressure and electrical storage mode, to effect a regenerative mode that attains low fuel consumption.

Abstract: A micro-turbine engine has been designed using vertically simple geometry, such that the engine components are designed with features that are defined geometrically, but not necessarily manufactured, by extruding two-dimensional features along a primary direction. This design approach reduces manufacturing and assembly costs. The present invention discloses designs to improve micro-turbine engine performance, and methods of manufacturing components that further reduce cost. The design improvements include methods of implementing a multi-stage micro-turbine engine using nested stages and nested flow paths, usage of multi-phase fuel injectors and supercritical fuel injectors to increase fuel flexibility and burner efficiency, and method of cooling a turbine rotor by building cooling blades on the opposite side of the rotor that act as a fluid pump to provide cooling by convection. The manufacturing methods include methods to build alignment features into components to improve ease of assembly, methods for manufacturing combustor components using sheet metal, and methods for manufacturing features that are not aligned with the primary direction of the vertically simple component.

Abstract: The present invention provides a miniature gas turbine engine for power generation. The engine has a highly integrated unitary rotor shaft where turbine, compressor and shaft are made in one piece in one fabrication process. The turbine and compressor are positioned back to back on the shaft in an overhung configuration, allowing the front bearings to be located in the cold zone of the engine. Preferably, the Mold SDM fabrication technique is utilized to make the unitary rotor shaft in one monolithic part out of ceramics such as silicon nitride, eliminating the need for post process assembly while strengthening the integrity, reliability, and performance of the unitary rotor shaft. Integrated with a permanent magnet in the unitary rotor shaft, the miniature gas turbine engine can generate electric power of 1 kW or less. Additionally, the axial length of the miniature gas turbine engine is about 100 mm or less. The miniature gas turbine engine according to the present invention is therefore particularly useful for powering lightweight, self-sustaining mobile devices such as unmanned vehicles and-autonomous robots.
