Abstract: A method of cooling a gas fueled engine driven intercooled air compressor comprises providing the intercooled air compressor, a gearbox, and the gas fueled engine. The method includes flowing a liquid coolant from a liquid coolant supply to each of the gearbox and an intercooler of the intercooled air compressor. The method comprises recombining the liquid coolant after the gearbox and the intercooler. The method includes directing the recombined liquid coolant via multiple paths to cool the gas fueled engine. The method comprises recombining the liquid coolant after the liquid coolant has passed through the multiple paths.

Abstract: The present invention discloses a novel apparatus and methods for augmenting the power of a gas turbine engine, improving gas turbine engine operational flexibility and efficiency, and reducing the response time necessary to meet changing demands of an electrical grid. Improvements in power augmentation and engine operation include systems and methods for providing rapid response given a change in electrical grid.

Abstract: A pilot fuel nozzle configuration for use in a combustor is disclosed having a natural frequency outside the range of the operating frequencies of a gas turbine engine. Multiple embodiments are disclosed for the improved pilot fuel nozzle including configurations for newly manufactured nozzles, repair to existing pilot nozzles, as well as multiple natural frequency levels for the improved pilot fuel nozzle. The pilot fuel nozzle comprises an elongated housing, first and second flanges, and a nozzle tip, with the first flange fixed to the elongated housing at a first end and the nozzle tip fixed to the second end, opposite of the first end. The second flange is fixed along the elongated housing and is used for attaching the pilot fuel nozzle to a combustor. The present invention incorporates an increased wall thickness along at least a mid-span portion of the pilot nozzle to increase the stiffness and change the natural frequency.
