Beschreibung
Zusammenfassung:	A plurality of individual thin wall, arcuate (e.g. airfoil shaped) core elements are formed in respective master dies to have integral interlocking locating features, the individual core elements are prefired in respective ceramic setter supports to have integral locating features, the prefired core elements are assembled together using the locator features of adjacent core elements, and the assembled core elements are adhered together using ceramic adhesive introduced at internal joints defined between mating interlocked locating features. The multi-wall ceramic core assembly so produced comprises the plurality of spaced apart thin wall, arcuate core elements and joined together by at the internal joints defined between the adhered interlocked locating features.
