    Abstract: A tube coupling for coupling a first tube and a second tube. The tube coupling includes an inner shroud including a ball portion and an outer shroud including a socket portion. The socket portion receives the ball portion. The tube coupling includes a compressive ring configured to elastically compress the outer shroud onto the inner shroud. The ball portion and the socket portion form a ball and socket joint. The ball and socket joint allows relative angular movement and relative axial movement between the inner shroud and the outer shroud.

    Abstract: A combustor for a turbine engine includes a combustion chamber including an outer liner and an inner liner, and an annular dome. A plurality of first mixing assemblies includes a pilot mixer and a first main mixer, the first mixing assemblies disposed through the annular dome. The pilot mixer injects a pilot mixer fuel-air mixture axially into a first combustion zone, and the first main mixer injects a first main mixer fuel-air mixture radially into the first combustion zone. A plurality of second mixing assemblies includes a second main mixer, the second mixing assemblies being axially aft of the plurality of first mixing assemblies. The second main mixer injects a second main mixer fuel-air mixture radially into a second combustion zone that is axially aft of, and separate from, the first combustion zone.

    CPC classification number: F16L27/04

    Abstract: A tube coupling for coupling a first tube and a second tube includes an inner shroud located circumferentially around a first tube distal end at an inner shroud distal end, the inner shroud distal end having one or more radial teeth, an outer shroud having a first outer shroud distal end and a second outer shroud distal end, the first outer shroud distal end located circumferentially around a second tube distal end and the second outer shroud distal end located circumferentially around the inner shroud distal end, and a band configured to elastically compress the first outer shroud distal end onto the inner shroud distal end. The band elastically compresses the first outer shroud distal end and the inner shroud distal end such that the one or more radial teeth are swaged into an outer surface of the first tube.

    Abstract: Systems, apparatus, articles of manufacture, and methods are disclosed for an acoustic damping device. An example apparatus includes a first channel defining a first volume, the first channel open on a first end and closed on a second end, a second channel surrounding the first channel and defining a second volume, and a plurality of discs oriented within the first channel, respective discs of the plurality of discs including an opening in a center of the respective disc to allow at least one of a fluid or acoustic oscillation to move from the first end to the second end, the first channel including a plurality of apertures dispersed along an outer wall of the first channel and between the plurality of discs, the apertures to facilitate transfer of at least one of the fluid or the acoustic oscillation from the first channel to the second channel.

    IPC: F01D11/00

    Abstract: A gas turbine engine including a wall assembly, a seal assembly, and a member extended through the wall assembly is provided. The wall assembly defines an opening through which the member is extended, and the wall assembly defines a first side and a second side opposite of the first side along a direction of extension of the member through the wall assembly. The seal assembly includes a retaining portion extended at least partially co-directional to the member. The retaining portion is configured to couple around the member and extend through the opening. The seal assembly further includes a locking portion configured to sealingly attach to the wall assembly and the retaining portion at an interface between the locking portion and the retaining portion.
