Abstract: A gas turbine engine exhaust system includes a liner extending along an axial direction and a radial direction and circumscribing a combustion plenum, a high pressure plenum circumscribing the liner along the radial direction, a structural component circumscribing the high pressure plenum along the radial direction, and a leaf spring fastener arranged within the high pressure plenum. The leaf spring fastener is arranged between the liner and the structural component.

Abstract: A regulator system includes a slidable ramp intermediate a secondary flow path and a primary flow path of a gas turbine engine nozzle section.

Abstract: A proximity switch (20, 20A) that snaps quickly and locks between first and second positions of movable electrical contacts (32). A magnet (42) moves a first shaft (26) toward a magnetic target (62) when the target is proximate a sensor end (43) of the switch housing (22). A spring (44) urges the first shaft (26) away from the sensor end. Movement of the first shaft causes a second spring (64) to urge a second shaft (28) in the direction of the first shaft. Next the second shaft is released (52) to move in the direction urged by the second spring. The switch may be adapted to a client cable pin configuration via an adapter plug (80) in the housing with a flexible interconnection circuit (82) folded in a chamber between the adapter plug and leads from fixed electrical contacts (38) of the switch.

Abstract: An engine has a blade, a casing surrounding the blade, an seal ring, and a passive system for connecting the seal ring to the casing and for accommodating thermal expansion of the seal ring relative to the casing so as to maintain blade tip clearance control. The passive system may include at least one, metallic Z-band extending between the casing and the seal ring.

Abstract: A retractable exhaust liner segment between a gas turbine engine and an exhaust duct.

Abstract: An exemplary turbine engine link assembly includes a link extending longitudinally from a rod end and terminating at a hemispherical end. The rod end is secured to an engine liner or an engine casing. The hemispherical end is biased toward a corresponding hemispherical recess in the engine liner or in the other of the engine liner or the engine casing.

Abstract: A tie rod includes a gusset which extends between a rod and a base.

Abstract: A nozzle assembly for a gas turbine engine includes a door axially slidable relative to a passage in communication with a secondary flow path to regulate the secondary flow though the passage.

Abstract: An example turbine engine assembly includes a first attachment structure secured to an engine casing or an engine liner. A second attachment structure is secured to the other of the engine casing or the engine liner. The assembly further includes a link having a rod portion extending longitudinally from a hemispherical end portion and terminating at a rod end portion. The hemispherical end portion is received within a recess defined by the first attachment structure. The rod end portion is secured relative to the second attachment structure to limit relative movement between the engine casing and the engine liner.

Abstract: Gas turbine engine systems involving variable nozzles with sliding doors are provided.

Abstract: Gas turbine engine systems involving flexible panels are provided. In this regard, a representative flexible panel assembly for a gas turbine engine includes: a flexible panel operative to define at least one of a throat area and an exit area of a nozzle of a gas turbine engine, the panel being further operative to selectively exhibit a range of positions to regulate exhaust of the engine.

Abstract: Systems and methods for determining relevance ratings for keywords associated with content are disclosed. A quantitative degree of relevance of keywords for a piece of content is determined by querying several reviewers. System users have a keyword record listing the keywords associated with content that a user has exhibited a threshold of interest in. Moreover, a cumulative value for the keywords is maintained by adding the degree of relevance of content keywords to the cumulative value of the keyword in the user's record. By finding correspondences between keywords in a user's record and keywords for pieces of content, advertisements, or other people using the system, a user's interest may be determined, and recommendations for content, advertisements, and potential friends or business contacts may be made to the user.

Abstract: A regulator system includes a slidable ramp intermediate a secondary flow path and a primary flow path of a gas turbine engine nozzle section.

Abstract: Systems and methods for representation of a user in a social networking environment are disclosed. In one aspect of the present disclosure, a method of a social networking environment includes managing anonymity levels of a set of user content provided by a user to the social networking environment. The set of user content includes a first content subset having a first anonymity level corresponding to a privacy setting of a public status, a second content subset having a second anonymity level corresponding to a privacy setting of a peer status, and/or a third content subset having a third anonymity level corresponding to a privacy setting of a private status.

Abstract: Systems and methods for content ranking and reviewer selection are disclosed. In one aspect of the present disclosure, a method of content review includes receiving submitted content and identifying reviewers based on a set of criteria. The submitted content can be presented to the reviewers and ratings of the submitted content can be received from the reviewers. In another aspect of the present disclosure, a method of rating reviewers includes providing content to a reviewer to be scored no the scale. The score provided by the reviewer user is recorded and the amount of time for the reviewer to score the content is tracked. Reviewer user rating can be adjusted based on the amount of review time.
