Abstract
A casting core assembly has: a first ceramic piece including a projecting post; a second ceramic piece including a socket; and a ceramic filler material between the post and the socket. In transverse section at at least one location one of the post and socket has a configuration of: three circumferentially offset radial peaks of a peak radius (RPMAX, RSMAX); and three radial troughs of a trough radius (RPMIN, RSMIN) not more than 98.0% of the peak radius.

A casting core assembly comprising:
- a first ceramic piece including a projecting post;
- a second ceramic piece including a socket;
- and
- a ceramic filler material between the post and the socket,
- wherein the post and socket are shaped so that with the post centered within the socket in transverse section at at least one location the post and socket define a gap having:
- three circumferentially offset first locations of local minimum radial span;
- and
- three circumferentially offset second locations of local maximum radial span.
5 more elements
A casting core assembly comprising:
- a first ceramic piece including a projecting post;
- a second ceramic piece including a socket;
- and
- a ceramic filler material between the post and the socket,
- wherein the post and socket are shaped to provide means for improving flow of the ceramic filler while preserving a centering effect.
