摘要： An assembly for an aircraft propulsion system includes an upstream cowl and a downstream cowl. The upstream cowl extends axially from a first upstream end to a first downstream end. The upstream cowl includes an inner barrel panel, an outer barrel panel, and a bulkhead. The bulkhead extends radially between and connects the inner barrel panel and the outer barrel panel at the first downstream end. The downstream cowl extends axially from a second upstream end to a second downstream end. The downstream cowl includes a cowl panel and a seal assembly. The seal assembly includes a seal frame and a seal member. The seal frame is mounted to the bulkhead. The seal member is mounted to the cowl panel. The seal member includes a first radial portion projecting away from the cowl panel. The first radial portion is located at the second upstream end.

摘要： A system for limiting deflection of an exhaust sidewall liner on a variable geometry exhaust duct uses a spacer and a T-bolt. The system connects the exhaust sidewall liner to the static structure on a variable geometry exhaust duct. The spacer includes a chimney having a first side and a second side opposite of the first side, an aperture extending from the first side to the second side, a flange disposed on the first side, and at least one anti-rotation tab disposed on the second side near an edge of the second side. The T-bolt includes an elongated shaft that extends along an axis and having a diameter, and a head having at least one straight edge connected to an end of the shaft. The at least one straight edge engages with the anti-ration tab, thereby preventing rotation of the stud T-bolt about the axis.

摘要： A sealing assembly may include a support, an engine component, and a seal. The engine component may be mounted relative to the support to define a gap between the engine component and the support. The seal may be arranged between the support and the engine component to block gasses from passing through the gap. The seal may be adapted to compress and expand to fill the gap during expansion and contraction of the adjacent components that occurs during operation of a gas turbine engine including the sealing assembly.

摘要： A seal segment includes a flapper seal, a wire mesh acting as a hinge for the flapper seal, and a spring. The flapper seal has a first surface and a second surface. The wire mesh includes a first section connected to the first surface of the flapper seal and a second section connected to the first section. The spring includes a first end that is in contact with the first section of the wire mesh to apply pressure to the first surface of the flapper seal and a second end adjacent the second section of the wire mesh.

摘要： A sealed joint may include a first plate with a seal land, a second plate that moves relative to the seal land, and a seal connected to the second plate. The seal may extend laterally between a first seal end and a second seal end. The seal may include a plurality of seal elements that extend longitudinally between a first seal side and a second seal side. A first of the seal elements may extend laterally from the first seal end towards a first seal segment, which is separated from the second plate by an airflow channel. The second of the seal elements may extend laterally from the second seal end towards a second seal segment, which is located between and engaged with the first seal segment and the seal land.

摘要： A seal assembly seals an interface between adjacent liner sections. The seal assembly comprises a seal carrier mounted to a first plate, a seal body overlapping at least a portion of the seal carrier to define a plane of travel between the seal body and the seal carrier, and at least one resilient member configured to bias the seal body against a second plate. The seal carrier includes an indented portion that extends radially inward of the plane of travel.
