Abstract: A torch ignitor system for a combustor of a gas turbine engine includes a torch ignitor, the torch ignitor including a combustion chamber oriented about a torch axis, the combustion chamber having axially upstream and downstream ends defining a flow direction through the combustion chamber, along the axis. The torch ignitor includes a cap defining the axially upstream end of the combustion chamber and oriented about the axis, wherein the cap is configured to receive a fuel injector and at least one glow plug. The torch ignitor includes an elbow connected to the downstream end of the combustion chamber for diverting combustion products along an ignition jet flame axis that is off of the torch axis for injection of combustion products into a gas turbine engine combustor. The torch ignitor further includes a tip at a downstream end of the elbow for issuing the injection of combustion products.

Abstract: A fuel injector for a gas turbine engine includes a fuel inlet fitting for receiving fuel, with a feed arm mounted to the inlet. The feed arm has a lattice support structure. The lattice support structure may include a plurality of three-dimensional elements, a first conduit, and a second conduit in fluid communication with the inlet for conveying fuel from the inlet fitting through the feed arm, wherein the conduits are intertwined with each other, and a nozzle body operatively connected to the feed arm for injecting fuel from the conduits into a combustor of the gas turbine engine.

Abstract: A fuel injector includes a fuel nozzle configured to issue a spray of fuel from a fuel outlet in a downstream direction along an injection axis. The fuel nozzle includes a nozzle body that defines a main flow passage therethrough. An injection fuel line is in fluid communication with the fuel nozzle to supply fuel to the fuel nozzle. A torch ignitor with a flame outlet opens into the main flow passage of the fuel nozzle for issuing flame into the main flow passage. The flame outlet meets the main flow passage at a position that is downstream of the fuel outlet with respect to the downstream direction along the injection axis.

Abstract: A method of producing compressed air for use onboard an aircraft includes receiving compressor discharge air into an air channel of a fuel injector. The method also includes cooling the compressor discharge air within the air channel by heat exchange with fuel flowing in the fuel injector, and issuing cooled air from the internal air channel out of an engine case as a source of compressed air.
