ABSTRACT:
A fuel injection system for use in the combustor section of a gas turbine engine is provided with first and second manifolds of toroidal configuration. First outlet nozzles of a plurality of fuel injectors associated with the first manifold are positioned at spaced circumferential locations lying in a common plane at similar radial distances from the centerline of the engine. Second outlet nozzles of a plurality of fuel injectors associated with the second manifold are similarly positioned but evenly spaced from the first outlet nozzles. Fittings for the fuel injectors are joined by means of flexible tubing and are similarly joined to a fuel inlet fitting for connection to a source of fuel. By providing a pair of separate manifolds and flexible tubing interconnecting the fittings of adjacent pairs of fitting for the injectors, outlet nozzles for the fuel injectors can achieve a more dense configuration, their assembly and maintenance can be substantially simplified, and vibratory stresses are minimized.
