Gas turbine engine blade mounting arrangement

摘要

A mounting arrangement for a gas turbine engine blade (70) having a root (80) employs a lightweight, simple and economical leaf spring spacer (125) which biases the blade root (80) in a radially outward direction to minimize unwanted movement of the root (80) within a conforming slot (85) in a blade hub (60) under conditions such as windmilling when centrifugal force alone is inadequate to tightly seal the root (80) within the slot (85).
