Abstract
The present invention relates to a ceramic core used in the manufacture, by lost wax casting, of a turbomachine blade with cooling cavities and a squealer, comprising at least one main core, wherein the main core (10) comprises an element (10B) shaped so as to constitute the squealer and an element (10SB) shaped so as to constitute at least one cavity beneath the squealer, the two elements leaving between them a space (13) shaped so as to constitute, at least in part, the bottom wall of the squealer. In particular, the elements (10B and 10SB) are joined together by ceramic rods (TG).
