Segmented composite inner shrouds |
摘要 |
A shroud for supporting the vanes in the hot sections of a gas turbine engine is comprised of composite segments retained in a metal ring. The metal ring has a positive coefficient of expansion, while the segments have a zero (or much smaller) coefficient. When the ring is heated and grows, it carries the segments with it, so that there is an apparent corresponding growth of the segments.
