Abstract: An entryway system includes a divided volute turbocharger having variable turbine geometry (VTG). The turbocharger includes a turbine housing, first and second volutes separated by a wall having a first and second tongue, and a turbine housing outlet. The system also includes a turbine wheel disposed in the turbine housing and a vane ring disposed in the turbine housing between the turbine wheel and the volutes. The system includes design modifications of one or more of the VTG components and/or locations of such components to manipulate the aerodynamic forces and/or subsequent mechanical loads in the VTG mechanism of the entryway system to mitigate VTG component wear during normal usage.

Abstract: A rotating detonation combustor system includes a rotating detonation combustor having an outer wall, and inner wall, and a combustion chamber configured to receive a fuel and an oxidizing agent and expel exhaust gas. The rotating detonation combustor system also includes a turbine wheel in fluid communication with the combustion chamber and configured to rotate upon receiving the exhaust gas, a shaft rotatable with the turbine wheel, and a compressor wheel rotatable with the shaft, in fluid communication with the combustion chamber, and configured to deliver compressed oxidizing agent to the combustion chamber. The rotating detonation combustor system further includes an electric machine rotatable with the shaft. The electric machine is configured to convert at least one of rotational motion of the shaft to electrical energy, and electrical energy to rotational motion of the shaft.

Abstract: An electric generator system includes a rotating detonation combustor having an outer wall, an inner wall, and a combustion chamber configured to receive a fuel and an oxidizing agent and expel exhaust gas. The electric generator system also includes a first turbine wheel in fluid communication with the combustion chamber and configured to rotate upon receiving the exhaust gas, a shaft rotatable with the first turbine wheel, and a compressor wheel rotatable with the shaft, in fluid communication with the combustion chamber, and configured to deliver compressed oxidizing agent to the combustion chamber. The electric generator system further includes a second turbine wheel in fluid communication with the first turbine wheel and configured to rotate upon receiving the exhaust gas from the first turbine wheel, and an electric generator rotatable with the second turbine wheel and configured to convert rotational motion of the second turbine wheel to electrical energy.

Abstract: A rotating machine for delivering a working fluid to a system includes a compressor housing defining a compressor housing interior and partially defining a flow path. The rotating machine also includes a shaft and a compressor wheel disposed in the compressor housing interior. The rotating machine additionally includes a backplate coupled to the compressor housing and further defining the flow path. The backplate and the compressor housing are configured to direct working fluid from the compressor housing interior through the flow path. The backplate defines a working fluid connection adjacent the compressor wheel and/or the flow path such that the working fluid connection is fluidly coupled to the flow path and such that the compressor wheel delivers working fluid from the compressor housing interior and the working fluid connection to the flow path.
