Patent ID: 7703286

Claim:
A mounting system for an internal fuel manifold of a gas turbine engine comprising a series of supports spaced apart about the internal fuel manifold, the internal fuel manifold being annular and having at least one fuel conveying passage therein in fluid flow communication with a plurality of fuel injection nozzles disposed along the internal fuel manifold and adapted to spray fuel into a combustor, the series of supports including a fuel inlet assembly connected to the internal fuel manifold and providing fuel flow to the fuel conveying passage, the fuel inlet assembly having an internal fuel inlet tube defining a fuel flow passage therein, the internal fuel inlet tube having a first end engaged to the internal fuel manifold and an opposed second end received within an opening in a fuel fairing, a thin-walled tubular heat shield surrounding the internal fuel inlet tube and being spaced apart therefrom throughout a complete length of both, the heat shield having a first diameter at a distal end thereof engaged with the internal fuel manifold, a second diameter at a proximal end thereof matingly received within said opening in the fuel fairing and a third diameter at a flange portion thereof proximate yet spaced away from the second end, the third diameter being greater than the second diameter, an annular bushing being disposed within said opening between said fuel fairing and said proximal end of the heat shield, the annular bushing having an inside diameter greater than the second diameter and smaller than the third diameter, the flange of the heat shield defining a shoulder projecting radially outwardly from said proximal end and retaining the bushing in place on said proximal end of the heat shield and within said opening of the fuel fairing, the bushing being slidingly received over said proximal end of the heat shield and prevented from further distal displacement by said flange.
