Abstract: A monolithic heater body may include a combustor body, a hot-side heat exchanger body, and an eductor body. The combustor body may define a combustion chamber and a conditioning conduit circumferentially surrounding the combustion chamber. The conditioning conduit may fluidly communicate with the combustion chamber at a distal portion of the combustion chamber. The hot-side heat exchanger body may define a hot-side heat exchanger that includes a heating fluid pathway fluidly communicating with a proximal portion of the combustion chamber. The eductor body may define an eduction pathway fluidly communicating with a downstream portion of the heating fluid pathway and a proximal portion of the conditioning conduit.

Abstract: A controller for a rotary machine includes a processor and a memory coupled to the processor. The memory is configured to store operating modes of the controller. The operating modes include a normal operating mode and a fault tolerant operating mode. The controller is configured to receive a signal from at least one sensor and determine an operating state of the rotary machine based on the signal. The controller is also configured to switch the operating modes based on the determined operating state of the rotary machine and regulate at least one electromagnetic bearing and at least one flow control device. The controller is further configured to adjust at least one of the at least one electromagnetic bearing and the at least one flow control device in the fault tolerant operating mode.
