Tool and method for determining impeller leading edge conformity

Abstract

A validation tool for determining conformity of leading edges of vanes on an impeller of an aircraft engine includes a support and a probe element. The support has a base and a spindle extending away from the base, the base being configured to be received on a reference surface of the impeller and the spindle defining a spindle axis. The probe element is rotatably mounted on the support and includes an annular body defining a central bore matingly receiving the spindle of the support therein. The probe element is rotatable about the spindle axis and includes a conformal probe thereon extending axially toward the base of the support. The conformal probe is configured to have a clearance fit with multiple of the leading edges at a same span-wise position of each, when the probe element is rotated on the spindle of the support.
