Abstract
A fuel injector assembly for dispensing fuel in the combustion chamber of a gas turbine engine, includes in one embodiment an elongated, multi-layered, convoluted nozzle feed strip having an internal passage for directing fuel through the length of the strip from the inlet end to an outlet end; and a cylindrical, multi-layered fuel dispensing nozzle unitary with the feed strip and fluidly connected to the outlet end of the feed strip for dispensing the fuel. The multi-layered feed strip and nozzle allow complex porting of fuel circuits through the injector. The internal fluid passages through the feed strip and nozzle are formed by etching. In another embodiment, the feed strip can be used for directing fuel from the manifold to one or more fuel injectors.
