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.Field of SearchRadially outermost flow defining wall adjustableRadially inwardly movable wall At least three pivoted flaps form outlet With adjustable upstream flow path portion DISTRIBUTOR HAVING THERMAL EXPANSION JOINT, DIFFERENTIALLY EXPANDING MATERIALS OR INSULATION TERMINAL OUTLET FORMED BETWEEN PARTS MOUNTED FOR RELATIVE MOVEMENT | |
