<p>A seal assembly (38) is provided between an exhaust flap (26) and a nozzle sidewall (18) of a gas turbine engine exhaust nozzle. The assembly includes a housing (42) fixedly joined to the exhaust flap (26) and a plurality of adjoining plungers (54) slidably disposed in the housing and each including a top extending outside a housing opening for defining a seal line (60) for contacting the nozzle sidewall for sealing the exhaust gases from flowing therebetween. The seal lines collectively define a seal first contour (18b) being complementary to a first contour of the nozzle sidewall (18). A tie rod (74) extends through the plungers and joins the plungers to the housing. The tie rod is flexible for allowing the plungers to rotate perpendicularly to the tie rod so that the seal lines collectively form a seal second contour (18c), different than the seal first contour, to conform to a second contour of the nozzle sidewall which is different than the nozzle sidewall first contour. <IMAGE></p> |
