ROTOR BLADE CUFF MEASURING TOOL AND METHOD

摘要

A measuring tool for a blade cuff mounted on a rotor blade assembly includes a cam follower assembly which simulates a longitudinal profile of an ideal blade cuff within a contour plane. A cam lock locks the gauge at a desired longitudinal position along a central axis to measure a radial plane defined around the blade cuff as the blade cuff profile fixture is rotated relative the base and cam follower assembly. A master block is removably mounted to the blade cuff fixture to simulate an ideal blade cuff such that the gauge may be zeroed thereon. Once zeroed, and after removal of the master block, the cam follower assembly provides a continuous zero position for the gauge such that any deviations from the ideal profile anywhere on the blade cuff is indicated on the gauge.
