摘要： An exhaust nozzle for a gas turbine engine is provided which includes a plurality of flaps and an abradable coating. Each flap includes seal surfaces with depressions disposed therein. The flaps are disposed about a structure within the engine, and are pivotly attached to that structure. Adjacent flaps overlap along the seal surfaces, and movement of the nozzle causes relative motion between the adjacent flaps. The abradable coating is attached to the seal surfaces, and contact between adjacent flaps causes the abradable coating to abrade. The remaining abradable coating fills the depressions within the seal surfaces.
