Patent ID: 7568344

Claim:
A fuel manifold assembly positionable around a combustor of a gas turbine engine for distribution of fuel to a plurality of fuel injectors, the manifold assembly comprising: a plurality of fuel injector base sections for connection with the respective fuel injectors; and a plurality of manifold segments interconnecting the respective fuel injector base sections, each of the manifold segments including a fire protective sleeve and a composite tube extending within and through the fire protective sleeve, the composite tube having a core layer including a polymer material, the core layer having a joint with one of the fuel injector base sections, a metallic braid layer surrounding the core layer, and a hydrostatic flow barrier disposed between the core layer and the metallic braid layer for preventing the polymer material of the core layer at the joint thereof from flowing through the metallic braid layer under an elevated temperature and compressed condition; and wherein each fuel injector base section comprises a pair of fitting portions, each of the fitting portion being inserted into an end of one manifold segment and retained in position by a retainer, the retainer being disposed between the metallic braid layer and the fire protective sleeve, compressing the end of the composite tube on the fitting portion.
