Dichtungseinrichtung für die Abgasdüse eines Gasturbinentriebwerks

摘要

A thermal shield and support structure assembly for a gas turbine engine is disclosed wherein the thermal shield can be removed while the support structure (24) is still mounted in the engine. The thermal shield in the form of a divergent seal baseplate (26) and the support structure is particularly useful for divergent seals and provides a removable baseplate having at least two hooks (40) disposed on the back side of the baseplate. The hooks have axially facing openings, preferably open in the forward facing direction and are operable to engage transversely extending pins (52) on the frame of the support structure. An axial retaining means to prevent the hooks from disengaging from the pins may also be used which, in one embodiment, provides a lug (60) having a first aperture (62) and extending away from the back side of the baseplate to engage a clevis (64) having two arms having second apertures alignable with the lug's aperture and a bolt (70) or other fastening means disposed through the apertures.
