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.

Abstract: A system of mounting segmented liner panels on the interior of an outer shell of a combustion chamber for a gas turbine engine. The system is effective to enable higher temperatures to be maintained thereby increasing engine efficiency while simultaneously guarding against structural failure. A plurality of concentrically disposed segmented liner panels are arranged in side by side circumferential relationship at successive axial locations. Each liner panel is fixed relative to the outer shell at one location proximate to a leading portion. In addition, each liner panel is restrained against radial movement relative to the outer shell, but relative axial and circumferential movement between the liner panel and outer shell is permitted. Mating spacer hooks and spring clip members are selectively engageable to mount a trailing portion of each liner panel to the outer shell. Lateral edges of adjacent liner panels are mutually configured to prevent escape of heat while accommodating circumferential expansion.
