Abstract: An auxiliary power unit (APU) includes a compressor, a turbine, a combustor, and a starter-generator unit all integrated within a single containment housing. The turbine has an output shaft on which the compressor is mounted, and the starter-generator unit is coupled to the turbine output shaft without any intervening gears. The rotating components are all rotationally supported within the containment housing using bearings that do not receive a flow of lubricating fluid.

Abstract: A radial turbine with a novel inlet and a outlet is combined with a centrifugal compressor, also having novel inlet and outlet, so as to obtain a turbocompressor unit wherein the respective inlets and/or exhausts of which are improved. The combination of above improves the overall efficiency of the turbocompressor unit. In addition, the combination limits the axial bulk of such a unit at the cost of a limited increase both in the cross section and the weight and structural complexity of the turbocompressor unit. Such a turbomachine: a radial turbine with an optional centrifugal compressor can be produced using two-microelectronic dimensional machining techniques of the microelectronic type.

Abstract: A microturbine power generation system includes an electrical generator, a turbine and a compressor intermediate the generator and the turbine. Rotating components of the turbine, compressor and electrical generator are secured together by a tie-bolt. The tie-bolt is pre-stressed such that faces of the rotating components of the turbine, electrical generator and compressor maintain contact during high-speed, high-temperature operation of the system. The tie-bolt includes a thermally less conductive short portion that is secured to the rotating component of the turbine wheel, and an elongated portion that extends through the rotating components of the compressor and electrical generator. The short, thermally less conductive portion of the tie-bolt inhibits heat from propagating from the turbine end towards the compressor. The short, thermally less conductive portion can be a titanium rod that is inertia-welded between the elongated portion of the tie-bolt and the rotating component of the turbine.

Abstract: A bearing system for use in a gas turbine engine includes a hermetically isolated bearing chamber formed in the vicinity of a high temperature portion of the main shaft of the engine. A dynamic pressure type gas bearing mounted in the bearing chamber frictionlessly supports the main shaft without lubricant when air is introduced into the bearing chamber from an air passage communicating the bearing chamber with the compressor of the turbine engine. Means for discharging air from the bearing chamber includes means forming a labyrinthine outlet flow path operating to regulate the flow rate of the discharged air.
