摘要： A method of reducing gas turbine engine distortion includes coupling a core gas turbine engine to a power turbine, coupling the power turbine to a thrust bearing support assembly through a frusto-conically shaped structural support such that the net axial thrust of the coupled core gas turbine engine and power turbine reacts through the thrust bearing support assembly at engine centerline to facilitate minimizing distortion of the core gas turbine engine casing, and supporting the thrust bearing support assembly such that all of the remaining thrust generated by the core gas turbine engine and the power turbine is reacted to ground.

摘要： An active air pressure control apparatus for a bearing sump cavity in a gas turbine engine includes a bearing assembly supporting a rotatable shaft that connects a rotatable power turbine and a rotatable compressor. The active air pressure control apparatus also includes a sump cavity surrounding the bearing assembly, a sump pressurization cavity in flow communication with a source of pressurized air and in flow communication with the sump cavity, and a sump vent tube in flow communication with the sump cavity and an air/oil separator. The active air pressure control apparatus includes an adjustable valve in the sump vent tube, and a controllable blower in flow communication with the sump vent tube.
