Abstract

Disclosed is an ECA probes assembly capable of providing reliable and durable ECA inspections of dovetail slots without the use of an external guiding mechanism. The design combines a novel universal probe manipulator with a probe support suited for a wide range of probe supports which fit a rage of turbine disks. The probe support embodies a rigid yet expandable core, exerting a force pushing the array probe against the inner cavity of the dovetails. The pushing force is strategically located in critical areas of the dovetail leading to array probe to be self-guiding into the dovetail, and to provide optimum performance with consistent and stable lift-off.
