Abstract : An exhaust nozzle flap capable of resisting high exhaust temperatures of turbojet engines is disclosed. The flap is composed of a two-part structure of high-strength metal, in a support member, combined with a heat resistant base member made from a ceramic of carbon-carbon material. The different materials in the base and support members, having substantially different rates of thermal expansion, are not bolted or riveted together, but attached in a unique manner to allow relative movement there between.
