Abstract:
1. A fuel distribution manifold system for a gas turbine engine comprising: a plurality of interconnected manifold segments, each manifold segment extending between a pair of fuel injector inlet fittings, each inlet fitting defining a fuel passage for directing fuel to an associated fuel injector, each manifold segment including at least one fuel transfer tube for transferring fuel between the fuel passages of two adjacent inlet fittings and a sealing tube that surrounds the at least one fuel transfer tube to provide leak protection therefor, wherein opposed end portions of the at least one fuel transfer tube are dynamically connected to the inlet fittings and opposed end portions of the sealing tube are statically connected to the inlet fittings, and wherein the sealing tubes of the plurality of interconnected manifold segments are sealingly isolated from the fuel passages of the inlet fittings.
