Abstract
A convergent/divergent nozzle for a gas turbine engine includes liners that are attached to the convergent flaps and seals. The liner is formed of two separate plates. By splitting the liner into two separate plates, a thermal break is provided between the two. Thermal stresses on a downstream plate are not as readily transferred to an upstream plate. External stresses on the upstream plate are not transferred as readily to the downstream plate. The two liner plate portions, and a separate backing plate all have faces that abut and are riveted together. These faces provide a flow blocker to maintain a lower pressure downstream of the flow blocker.
