Abstract: A rotating machine and associated method is disclosed that includes one or more cooling channels for providing a cooling fluid to a component. The cooling channels pass through a rotating component. The rotating machine further includes one or more particle separation slots in the rotating component in fluid communication with the one or more channels for removing particulate contamination.

Abstract: Embodiments of the invention can provide systems, methods, and an apparatus for thermally isolating a turbine rotor wheel. According to one embodiment, a method for thermally isolating a turbine rotor wheel can be provided. The turbine rotor wheel can include a pair of blade posts, or shanks, supporting respective turbine rotor blades such that a shank cavity is formed between respective blade posts. To thermally isolate the turbine rotor wheel, at least one seal operable to partition the shank cavity into an upper region and a lower region can be provided. In addition, this seal can be inserted within the shank cavity to partition the shank cavity into an upper region and a lower region. In doing so, cooling air flow can be divided between the upper region and the lower region so that the lower region can be maintained at a lower temperature than the upper region.

Abstract: A turbine engine includes a compressor, a combustor fluidly connected to the compressor and a first turbine operated by a combustion product formed in the first combustor. The turbine engine also includes a reheat chamber in which air, fuel, and exhaust gases from the first turbine are ignited to form a combustion product used to drive a second turbine. The engine further includes a controller that regulates at least one of an amount of fuel and compressed air delivered to the combustor and an amount of fuel, compressed air and exhaust gases delivered to the reheat chamber based on at least one turbine engine parameter measured by a sensor.
