A lock lug for inhibiting movement of a plurality of rotor blades includes a body and an engagement mechanism. The body is sized and configured to be received within the rim slot of the rotor disk and defines a dovetail receiving aperture. The engagement mechanism extends from the body and has a retracted configuration configured to allow entry and exit of a dovetail of at least one or more of the plurality of rotor blades into and out of the dovetail receiving aperture and an extended configuration configured to block the dovetail from entering the dovetail receiving aperture.

Methods and apparatuses for blade locking

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.

Acoustic damping device

An engine can utilize a combustor to combust fuel to drive the engine. A fuel nozzle assembly can supply fuel to the combustor for combustion or ignition of the fuel. The fuel nozzle assembly can include a swirler and a fuel nozzle to supply a mixture of fuel and air for combustion. Increasing efficiency and meeting emission needs can be met with the use of alternative fuels, which combust at higher temperatures or higher speeds than traditional fuels, requiring improved fuel introduction without the occurrence of flame holding or flashback.

A check valve assembly for a supply pipe. The check valve assembly includes a hinge pin, a first flapper, and a second flapper. The first flapper is pivotally coupled to the second flapper with the hinge pin. The check valve assembly also includes a stopper located between the first flapper and the second flapper. The stopper is configured to limit movement of the first flapper and the second flapper. The check valve assembly further includes a plate assembly located downstream of the stopper. The plate assembly is configured to break vortices formed in a fluid flow across the first flapper and the second flapper.

Check valve assembly

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.

Tube coupling

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.

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.

Seal assembly

In one exemplary embodiment of the present disclosure a fluid coupling assembly defining an axial direction, a radial direction, and a circumferential direction is provided. The fluid coupling assembly includes a male coupling including a first MC attachment interface, a second MC attachment interface, and an outer surface extending along the circumferential direction; a ferrule coupling including an FC attachment interface pressed against the first MC attachment interface, a lip extending along the radial direction, and an outer surface extending along the circumferential direction to define a circular shape; and a nut coupling including an NC attachment interface rotatably engaged with the second MC attachment interface, a flange extending along the radial direction and pressed against the lip of the ferrule coupling, and an inner surface extending along the circumferential direction to define a circular shape; wherein the outer surface of the male coupling, the outer surface of the ferrule, or the inner surface of the nut coupling includes a plurality of non-resilient protrusions spaced along the circumferential direction for contacting an opposing surface and increasing a loosening resistance of the fluid coupling assembly.
