A method for manufacturing a heat exchanger includes joining a first conductive sheet to a second conductive sheet to define a plurality of separate volumes in a blank envelope, creating an aperture in each separate volume in the blank envelope, and heating the blank envelope. The method further includes pressurizing each separate volume through the apertures, hot plastic forming the blank envelope into a formed envelope, and assembling a plurality of formed envelopes into a heat exchanger core, wherein the heat exchanger core includes a fluid passage outside of the formed envelopes, wherein the fluid passage is defined by adjacent formed envelopes, and wherein the fluid passage extends across a dimension of the heat exchanger core.

A sealing arrangement for a compressor that compresses a gaseous mixture of air and fuel includes a pressurized air supply duct for supplying pressurized air into a leakage pathway defined between a compressor wheel and a housing of the compressor, which leakage pathway leads from the main gas flow path into a bearing area of the compressor, the pressurized air being supplied at a pressure sufficient to ensure that air and gaseous fuel cannot flow from the main gas flow path through the leakage pathway into the bearing area. A portion of the pressurized air flows into the bearing area, while the remainder of the air flows outwardly and is either fed back into the main gas flow path or is combined with air and gaseous fuel that leaks past an outer seal and is recirculated back to the compressor inlet.

A recuperated gas turbine engine system and associated method employing catalytic combustion, wherein the combustor inlet temperature can be controlled to remain above the minimum required catalyst operating temperature at a wide range of operating conditions from full-load to part-load and from hot-day to cold-day conditions. The fuel is passed through the compressor along with the air and a portion of the exhaust gases from the turbine. The recirculated exhaust gas flow rate is controlled to control combustor inlet temperature.

An electrical power generating system is driven by a multi-spool gas turbine engine including at least first and second spools. The first spool comprises a turbine and a compressor mounted on a first shaft; the second spool has at least a turbine mounted on a second shaft that is not mechanically coupled to the first shaft. A main generator is coupled with one of the spools, and an auxiliary generator/motor is also coupled with one of the spools. Speed control of each of the generators is employed for controlling operation of the engine. The auxiliary generator/motor can operate in either a generation mode to extract power from its spool or a motor mode to inject power into its spool.

Multi-spool turbogenerator system and control method

An electrical power generating system and method wherein a generator is driven by an air-breathing engine. At any operating condition, for a given power output the engine efficiency is substantially optimized by controlling the rate of air flow through the engine in such a manner that the fuel/air ratio is controlled to maintain a high peak temperature imparted to the working fluid in the engine. The method and system of the invention eliminate the need for variable-geometry mechanisms in the engine, and also eliminate the need for variable-geometry combustors and pre-burners. The invention is applicable to various types of air-breathing engines that operate at low fuel/air ratios.
