Abstract: A system includes an air manifold, a fuel manifold and plurality of fuel injectors. Each fuel injector includes a fixture portion, a nozzle outlet, and a heat exchanger portion connecting between the fixture portion and the nozzle outlet. An air channel and a fuel channel are in thermal communication with one another for heat exchange between fuel and air passing through the heat exchanger portion. The respective inlet of the fuel channel of each of the fuel injectors in the plurality of fuel injectors is connected to the fuel manifold for fluid communication of fuel from the fuel manifold to the nozzle outlets for combustion. The respective outlet of the air channel of each of the fuel injectors in the plurality of fuel injectors is connected to the air manifold for fluid communication of air from the heat exchanger portions into the air manifold.

Abstract: A system includes an air manifold, a fuel manifold, and a plurality of fuel injectors. At least one of the fuel injectors includes a heat exchanger portion for supplying compressed, cooled air form the heat exchanger portion to the air manifold. An air valve is operatively connected to an outlet of the air manifold for controlling release of air from the air manifold. A controller is operatively connected to the air valve, wherein the controller includes machine readable instructions configured to control the air valve to regulate flow of air through the air valve based on fuel temperatures in the fuel channel. The machine readable instructions can be configured to cause the controller to flow air through the air valve in a heat exchange mode if a fuel temperature in the fuel injectors is below a predetermined fuel temperature.

Abstract: A tile for a combustor dome of a gas turbine engine includes a tile body defining an upstream surface and an axially opposed downstream surface with at least one injection orifice defined through the tile body from the upstream surface to the downstream surface. The tile body extends in a radial direction from a radially inner surface to a radially outer surface. The radially inner and outer surfaces define circular arcs that are concentric with one another. The tile body extends circumferentially from a first end face to a second end face. The first end face follows a sigmoid profile and the second end face follows a sigmoid profile configured to interlock with the sigmoid profile of the first end face of another identical tile body.
