摘要： In some embodiments, apparatuses are provided herein useful to sealing a gap, such as a gap between a gas turbine engine nozzle flap and sidewall. An apparatus for sealing such a gap may be a plunger seal that includes a plunger, a retaining element, a guide pin, and a biasing element. The plunger includes a sealing edge and an actuating edge having at least one recess and an opening formed therein. The biasing element and a portion of the guide pin are nested in the recess. The retaining element anchor the plunger to the retaining element. The retaining element also anchors the plunger seal to the housing When installed in a gap, the housing engages the flap and the plunger engages the sidewall. The biasing element is under compression and urges the guide pin into the actuating edge to urge the plunger toward the sidewall and seal the gap.

摘要： Apparatuses and methods are provided herein useful to sealing a dynamic gap between a moveable flap and a sidewall. The apparatus may be a seal assembly that includes a spring body, a clip coupled to a distal end of the spring body, and a wear shoe coupled to the clip. The spring body includes a flap arm adjacent the flap and a wall arm adjacent the sidewall. The flap arm and the wall arm bias away from one another when under compression in the gap. A distal end of the wall arm includes a first knuckle and a second knuckle that are pivotally coupled to the clip to create a hinge feature. The wear shoe is pivotally coupled to the clip to create another hinge feature. A distal end of the flap arm includes a skirt that is received by the clip seal an interior space of the spring body.

摘要： Apparatuses are provided herein useful to sealing a gap between a movable flap and a stationary structure, such as a gap between a gas turbine engine nozzle flap and a corresponding sidewall. An apparatus for sealing such a gap may be a dynamic skirted leaf seal which may include a flap arm, a wall arm opposite the flap arm, and a support arm disposed between the flap and wall arms. A distal end portion of the flap arm may comprise a first skirt and a distal end portion of the support arm may comprise a second skirt that engages the first skirt. When positioned in a gap, the skirted leaf seal may exert a force to urge the first flap arm towards the flap and to urge the wall arm and the support arm towards the structure to seal the gap.
