摘要： An oil scavenge system of a gas turbine engine in accordance with one embodiment of the present invention, comprises a housing defined about an axis of rotation, the housing confining an air/oil mixture in motion within the housing and defining an oil scavenge area below the axis of rotation. The housing further includes an outlet at a low location of the housing. A churning damper is supported within the housing and is located in the oil scavenge area. The churning damper includes at least one plate, allowing the air/oil mixture in motion to pass over or through the plate only in a peripheral area of the at least one plate to cause flow energy dissipation.

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.
