摘要： An assembly method is provided during which a first component is arranged with a second component. The first component is secured to the second component using a fastener assembly. The fastener assembly includes a fastener element and a washer. The fastener element includes a wrenching feature. The washer has a full-hoop annular body with a cylindrical outer surface. The securing includes: mating a socket device with the fastener element and the washer, the socket device engaging the wrenching feature and the cylindrical outer surface; and rotating the fastener element about an axis using the socket device to tighten the fastener assembly and clamp the washer axially between the first component and the fastener element. The socket device centers the washer to the fastener element during the rotating.

摘要： The composite seal structure includes a carrier ring and a seal element housed in an annular groove formed between a circumferential outer wall and two side walls of the carrier ring. The seal element has a first region in surface-to-surface contact with the annular groove and a second, seal-ing region protruding from the annular groove. A fastening arrangement couples the seal element and the carrier ring to one another. The fastening arrangement comprises a plurality of fastening pins circumferentially arranged around the axis of the carrier ring. Also disclosed is a method for manufacturing the seal structure.

摘要： A liner support system for an exhaust liner in an aircraft engine. The liner support system includes a plurality of posts that space the exhaust liner from the exhaust duct, the plurality of posts spacing the exhaust liner from the exhaust duct further supporting the exhaust liner. Each post includes an interface region adjacent to the back side of the exhaust liner sealed to the back side of the exhaust liner, a shank extending to a low pressure region, and a hollow passageway internal to the shank, providing fluid communication between the interface region and the low pressure region. The low pressure region results in pressure against the liner, pulling the liner adjacent the post interface region against the post while preventing fluid leakage between the exhaust liner and the interface region. The posts create a pattern of alternating pressures in the liner allowing for elimination of hangers.

摘要： A propulsion unit for an aircraft includes a gas generator; an air inlet; and a sealing system inserted axially between the air inlet and the gas generator. The sealing system has at least: a compression ring with a first axial end configured for mechanical connection to one of the gas generator and the air inlet. The compression ring also has a second opposite axial end configured to be axially separated from the other of the gas generator and the air inlet by an annular space. An annular seal is mounted in the space and configured to be axially compressed by reduction of the axial dimension of said space.

摘要： A nozzle comprises a combustion chamber having a downstream end and a divergent formed of a cone-shaped wall extending between an upstream end and a downstream end. The upstream end of the divergent is connected to the downstream end of the combustion chamber by an intermediate ring having an upstream flange fixed on a fixing flange secured to the combustion chamber and a downstream flange connected to the upstream end of the divergent. The intermediate ring having an inner channel present between the upstream and downstream flanges of the intermediate ring. A material able to take heat from the ring is present in the inner channel.
