Abstract: A rotating structure provides a first annular array of first radial scoops and a second annular array of second radial scoops arranged axially with respect to the first annular array of first radial scoops. A first component is arranged in an axially forward direction relative to the first annular array of first radial scoops. A second component is arranged in an axially aft direction relative to the second annular array of second radial scoops. A lubrication system includes at least one nozzle aimed at the first and second annular arrays of first and second radial scoops. A first lubrication delivery path fluidly connects the first annular array of first radial scoops to the first component along the axially forward direction. A second lubrication delivery path fluidly connects the second annular array of second radial scoops to the second component along the axially aft direction.

Abstract: A bearing support may include a central shaft, a flange shaft, and a tube boss. The central shaft may include a central longitudinal axis extending between a first end and a second end of the bearing support. The flange shaft may extend radially outward of the central shaft at an acute angle, relative to the central longitudinal axis from the first end to the second end, and the flange shaft may include a rim defining an aperture. The tube boss extends from the central shaft radially outward through the aperture, according to various embodiments. An annular channel may be between the rim and the tube boss.

Abstract: A seal seat includes an annular body and an extension. The annular body is disposed about a centerline axis. The extension is connected to and extends radially outward from the annular body. The extension includes first, second, and third portions. The first portion is connected to the annular body and is defined by axially opposed upstream and downstream wall faces. The first portion includes a fin connected to the upstream wall face. The second portion is connected to the first portion and extends substantially parallel to the annular body. The third portion is connected to the second portion and extends substantially parallel to the second portion.

Abstract: An oil supply assembly for a bearing damper of a gas turbine engine includes an oil supply tube configured to supply oil in a first direction. The assembly also includes a bearing support having a bearing damper path connecting the bearing damper to the oil supply tube and a bearing compartment path connecting a bearing compartment to the oil supply tube. The assembly also includes a check valve disposed within the bearing damper path and configured to allow fluid communication in the first direction from the oil supply tube to the bearing damper and block fluid communication in a second direction opposite the first direction.

Abstract: An oil tank mounting system for use on a structure of a turbine engine, includes three mounts with each mount configured to constrain the oil tank with a different number of degrees of freedom of movement. A first mount may have fix the oil tank in one degree of freedom, a second mount may fix the oil tank in two degrees of freedom, and a third mount may fix the oil tank in three degrees of freedom. This allows limited rotational and expansion movement while coupling the oil tank to the engine. The mount attachments may be embodied in rubber, with pins, or with spherical joints in a variety of configurations. Frangible pins may be used to absorb energy but still retain the oil tank in the event of a high energy event.

Abstract: A method for servicing a gas turbine engine includes disassembling a bearing compartment, providing access from a forward side of the gas turbine engine to a gearbox contained within said bearing compartment. The gas turbine engine provides a core flow path that extends from the forward side aftward in a core flow direction. The method includes servicing a component located within the bearing compartment. A method for servicing a gas turbine engine includes providing access from a forward side of a front center body assembly, and servicing a component located within a bearing compartment aft of the front center body assembly. The gas turbine engine includes a seal package located aft of a bearing package. A front wall is mounted to the front center body support and is removable from a front center body support to access at least one of the gearbox, the bearing package and the seal package.
