Abstract: A fuel injector for a turbine engine includes a fuel scheduling valve configured for regulation of fuel flow from a fuel inlet, in response to fuel pressure received at the fuel inlet. Primary, secondary and auxiliary fuel circuits receive fuel from the scheduling valve, and an electrically-controlled valve is provided in fluid communication with the auxiliary circuit, which electrically-controlled valve is adapted and configured to actively control fuel through the auxiliary circuit in response to a control signal.

Abstract: A heat exchanger includes a heat exchanger core, a pressure housing, and a flex beam. The pressure housing at least partially defines a core chamber. The flex beam extends between and connects the heat exchanger core and the pressure housing such that the heat exchanger core is suspended away from the pressure housing within the core chamber by the flex beam. The flex beam includes a core end connected to the heat exchanger core and a housing end spaced along the flex beam from the core end and connected to the pressure housing.

Abstract: An air cycle machine includes an outer housing, a first section arranged within the outer housing, and a second section arranged within the outer housing and operably coupled to the first section. The first section includes a first housing and a first rotatable component and the second section includes a second housing and a second rotatable component. At least a portion of a fluid flow path extending between an outlet of the first rotatable component and an inlet of the second rotatable component is arranged within the outer housing.

Abstract: The present disclosure provides for heat exchanger assemblies, systems and methods. More particularly, the present disclosure provides for radially-flowing cross flow heat exchanger assemblies and systems that increase primary heat transfer surface, and related methods of use. The present disclosure provides for a cross-flow heat exchanger assembly that can be packaged cylindrically or the like (or other self-enclosed shapes), and where the heat exchanger assembly also increases and/or maximizes primary heat transfer surface area by utilizing a weave-style or interwoven heat exchanger core. A first circuit flow path can be axial or circumferential in nature, and a second circuit flow path can be radial.

Abstract: A system includes an injector having a scheduling valve assembly and a nozzle in fluid communication with the valve assembly. The scheduling valve assembly is configured for regulation of flow from an inlet of the injector to the nozzle. The injector includes two fluid circuits between the inlet of the injector and two respective outlets of the nozzle for staged flow output from the nozzle. A first one of the two fluid circuits is a primary circuit, and a second one of the two fluid circuits is a secondary circuit. A solenoid valve is connected in fluid communication with the scheduling valve assembly, wherein the solenoid valve is configured to adjust position of a hydromechanical valve spool of the valve assembly.

Abstract: A system includes an engine case for a gas turbine engine defined around a longitudinal axis. An access opening is defined through the engine case for access from outside the engine case to a space inside the engine case. A combustor is housed in the space inside the engine case. The combustor includes an inner annular wall and an outer annular wall radially outboard from the inner annular wall. The inner annular wall includes a first rail on an upstream end thereof. The outer annular wall includes a second rail on an upstream end thereof. The first and second rails each include a respective access portion configured to receive line replaceable injector components from through the access opening of the engine case into the first and second rails to form a combustor dome of the combustor.
