An aircraft engine has: a compressor section having a compressor rotor rotatable about a central axis; a diffuser downstream of the compressor rotor, the diffuser including a diffuser ring extending circumferentially around the central axis; a bearing housing secured to the diffuser ring, the bearing housing contained within a volume located radially inwardly of the diffuser ring; and an air manifold secured to the diffuser ring, the air manifold defining inlets in fluid flow communication with the compressor section and an outlet in fluid flow communication with the volume.

A tube assembly for a gas turbine engine includes a rigid tube having first and second ends for connection to first port and second ports on the gas turbine engine. The first and second ports have different orientations providing for different installation vectors. The tube assembly further includes a tube adapter adjustably connected to the second port and a coupling, which, is, in turn, adjustably mounted to a distal end of the tube adapter for connection with the second end of the tube.

The gas turbine engine fuel manifold assembly includes a fuel manifold, and fuel nozzles secured to the fuel manifold and in fluid communication therewith. A fuel inlet connector has a body secured to the fuel manifold, and is in-line therewith. The fuel inlet connector has at least one connector outlet fluidly connected to the fuel manifold. The at least one connector outlet defines a fuel flow direction having a main component in a circumferential direction relative to the axis.

Fuel manifold assembly

A fuel supply assembly for a gas turbine engine includes at least one fuel transfer tube, at least one fuel nozzle, and at least one retaining bracket. The transfer tube and the nozzle are assembled in fluid communication with one another. The retaining bracket is fixedly attached to one of the nozzle and the transfer tube and displaceable relative thereto between a first position and a second position. A free end of the bracket is engageable with the other of the fuel nozzle and the transfer tube to retain the transfer tube to the fuel nozzle when the bracket is in the second position. The retaining bracket is disengaged from one of the fuel nozzle and the transfer tube in the first position so that the fuel nozzle and the transfer tube are disengageable from one another.
