摘要： An apparatus and method are provided for permitting free rotation of turbine nozzle vanes, while minimizing or eliminating leakage on the vane side-walls. The device incorporates a plurality of nozzle vanes arranged around the circumference of a radial or mixed inflow turbine. Each of the nozzles is individually attached to a rod positioned perpendicular to the flow direction. The nozzle rods in the circumferential array protrude through a movable annular back-wall, and are rotated by a linkage or gear. Between discrete movements of the vane mechanism, a bellows device is used to provide pressure-actuated force in the movable back-wall, thereby clamping the nozzle between the two surfaces. Prior to rotating the nozzles, pressure within the bellows interior is decreased via venting to cause a retraction of the back wall.

摘要： This disclosure relates to a highly efficient gas turbine engine architecture utilizing multiple stages of intercooling and reheat, ceramic technology, turbocharger technology and high pressure combustion. The approach includes utilizing a conventional dry low NOx combustor for the main combustor and thermal reactors for the reheat apparatuses. In a first configuration, there are three separate turbo-compressor spools and a free power turbine spool. In a second configuration, there are three separate turbo-compressor spools but no free power spool. In a third configuration, all the compressors and turbines are on a single shaft. Each of these configurations can include two stages of intercooling, two stages of reheat and a recuperator to preheat the working fluid before it enters the main combustor.

摘要： A heat exchanger for transferring heat between an external fluid and an internal fluid includes two or more heat exchange cells, each heat exchange cell having a top plate with an inlet aperture at one end thereof and an outlet aperture at the other end thereof, the top plate including a first surface, a second surface and peripheral edges. The heat exchange cell also includes a bottom plate juxtaposed with the top plate, the bottom plate having an inlet aperture at one end thereof and an outlet aperture at the other end thereof. The bottom plate includes a first surface, a second surface and peripheral edges. The peripheral edges of the top and bottom plates are attached to one another, the second surfaces of the top and bottom plates confronting one another and the inlet and outlet apertures of the top and bottom plates being in substantial alignment with one another. The attached top and bottom plates define a high pressure chamber between the second surfaces thereof. The inlet and outlet apertures of the top and bottom plates including substantially curvilinear S-shaped raised flange portions extending away from the first surfaces of the plates, the substantially curvilinear S-shaped raised flange portions terminating at interior edges bounding the apertures. Each heat exchange cell includes an internal finned member disposed between and attached to the second surfaces of the respective top and bottom plates, wherein the individual heat exchange cells are assembled one atop the other with the interior edges of adjacent heat exchange cells attached together for forming a compliant bellows structure capable of elastically absorbing deflections produced during thermal loading so that the heat exchange cells may move and flex relative to one another.

摘要： A heating chamber for supplying heated air in a Brayton engine or gas turbine plant including a compressor and turbine. The heating chamber includes a solar energy receiver that receives solar energy, converts it to heat, and heats air from the compressor. To supply additional energy that may be required for the turbine, fuel is injected into the air stream and a catalyst downstream of the solar receiver reacts the fuel with the air to provide additional energy.

摘要： A metallic-ceramic joint for a turbo-compressor spool is disclosed. A temperature-limited joint is moved from outside the bearings to between the bearings and near the center of the shaft joining the turbine and compressor. This placement can lower the temperature at and around the joint and reduces the sharp gradient (and associated thermal stress) naturally occurring between the turbine rotor and the cooler joint. The bearing closest to the compressor can be an oil bearing and the bearing closest to the turbine an air bearing. The bearing closest to the compressor and the bearing closest to the turbine can both be an oil bearing. The bearing closest to the compressor and the bearing closest to the turbine can both be an air bearing. Moving the metallic-ceramic joint between the bearings can provide sufficient isolation to enable the all-air bearing solution.
