Gas turbine engine nozzle apparatus including a nozzle flap slot seal

摘要

Apparatus for modulating the area of a gas turbine engine nozzle which provides for positive sealing between overlapping articulated flaps when the overlapped flap is axially slotted to receive a portion of the overlapping flap. An arcuate seal is attached to the overlapping flap by means of a floating connection, the overlapping flap dragging the seal therewith in the axial direction. A seat is mounted on either side of the slot to slidingly receive a pair of shoulders laterally extending from the seal. A portion of the seal is received within the slot and is so contoured as to partially define the nozzle flow path. A sleeve captures and supports the seal shoulders during their axial travel.
