Abstract
A flap for a variable area exhaust nozzle of a gas turbine engine, having a support structure and a gas shield having a plurality of gas shield segments connected to the support structure and adjacently arranged along a longitudinal direction of the flap corresponding to flow through the nozzle. Each of the gas shield segments has a flowpath section arranged to cooperate with a corresponding flowpath section of an adjacent gas shield segment to define a flowpath surface of the gas shield to bound flow through the nozzle. The gas shield segments are configured to permit the respective flowpath section to move longitudinally relative the support structure in response to thermal expansion of the gas shield.
