Abstract: Systems and methods for controlling a heat engine system are provided. One method includes initiating flow of a working fluid through a working fluid circuit having a high pressure side and a low pressure side by controlling a pump to pressurize and circulate the working fluid through the working fluid circuit and determining a configuration of the working fluid circuit by determining which of a plurality of waste heat exchangers and which of a plurality of recuperators to position in the high pressure side of the working fluid circuit. The method also includes determining, based on the determined configuration of the working fluid circuit, for each of a plurality of valves, whether to position each respective valve in an opened position, a closed position, or a partially opened position and actuating each of the plurality of valves to the determined opened position, closed position, or partially opened position.

Abstract: A method for assembling a gas turbine engine combustor is provided. The method includes providing a heat shield defined by a perimeter. The perimeter includes a radially inner edge, a radially outer edge, an axially inner edge, an axially outer edge, and an opening that extends from an upstream side of the heat shield to a downstream side of the heat shield. The method further includes coupling the heat shield to a domeplate such that the perimeter of the heat shield is positioned a distance downstream from an edge of the heat shield defining the opening. The method additionally includes coupling at least one fuel injector to the domeplate such that a portion of the fuel injector extends through the heat shield opening.

Abstract: A system including a seal cartridge is provided. The seal cartridge includes a housing defining a passageway that receives a driveshaft. A dry gas seal is circumferentially disposed about the passageway within the housing at a first axial location along the housing. A magnetic liquid seal is circumferentially disposed about the passageway within the housing at a second axial location along the housing. A fluid leakage cavity is formed between the dry gas seal at the first axial location and the magnetic liquid seal at the second axial location. An extraction port is disposed in the housing and enables recovery of a leaked fluid from the fluid leakage cavity.
