摘要： The present invention is directed to a combustor/turbine successive dual cooling arrangement in which the combustor has a one-piece hot combustor wall and front and rear cold combustor walls, and cooling air is forced under pressure through perforations in the cold combustor walls and impinges on the annular front and rear sections of the hot combustor wall for the backside cooling of the hot combustor wall. The exhaust combustor backside cooling air is directed to gain access to the hot end of the engine, that is, the turbine section, to cool the turbine components. The combustor/turbine successive dual cooling arrangement according to the present invention enables all the air typically used to cool the hot end of the engine downstream of the combustor, to be used as combustor backside cooling as well, to significantly reduce the amount of air needed for combustor and turbine cooling. Moreover, all the exhaust combustor backside cooling air must be used for turbine cooling and is never ingested into the combustion chamber, thereby avoiding negatively affecting the engine combustion emissions.

摘要： A floating collar assembly for damping vibration and sealing between a combustor and a fuel nozzle of a gas turbine engine. The combustor has a nozzle opening with an outer peripheral abutment surface and the nozzle is integral with an internal fuel manifold that is secured to the engine core relative to the combustor. The nozzle has a cylindrical body aligned with the nozzle opening and has a shoulder laterally extending from the nozzle body. An annular floating collar has a combustor face adapted for radial sliding engagement with the abutment surface, a central aperture adapted for axial sliding engagement with the cylindrical body and an outer bearing surface. A wave spring is disposed between the outer bearing surface of the floating collar and an inner surface of the nozzle shoulder, for maintaining sealing engagement, for damping vibration, and for impeding relative rotation between the nozzle and the combustor, while accommodating axial and radial relative displacement.
