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 or 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 therebetween.

An exhaust nozzle flap comprising: a support member having a first set of lugs at one end and a tip at its other end; a base member composed of heat resistant materials, said base member having a second set of lugs at one end and a retainer flap at its other end, said base member being attached to said support member in a manner which allows relative movement therebetween by having its second set of lugs interleaved with the first set of lugs of the support member and said retainer flap encompassing said tip of said support member thereby holding it in place while allowing for differences in thermal expansion between said support member and said base member; and a hinge pin inserted between said first and second set of lugs of said support member and said base member, said hinge pin thereby connecting said support member to said base member.
