Abstract

See full text

A ceramic mixture is shaped to form a ceramic core having a configuration which corresponds to the configuration of a cavity in an airfoil. The ceramic core is positioned between a plurality of arrays of burners. Flames from the burners burn organic material contained in the ceramic core. During burning of the organic material, the core is upright with a longitudinal central axis of the core in a generally vertical orientation. The ceramic core may be dipped in a ceramic material after having performed the step of burning organic material and prior to additional heat treatment of the ceramic core.
