Abstract

PURPOSE: To relax a stress concentration by forming an opening or a concave at a place or near to the place where an intersection with a casing trunk occurs via a speed ring of a stay vane.
CONSTITUTION: An opening or a concave 18 is formed at a place or near to the place where an intersection with a casing trunk 12 via a speed ring 14 of a stay vane 16 occurs. By this mechanism, a force flow can be made uniform as is shown by a stress distribution curve S3, hence the stress concentration can be relaxed.
