SYSTEM AND METHOD FOR INSPECTING FAN BLADE TIP CLEARANCE RELATIVE TO AN ABRADABLE FAN CASE

A system (100) and method for inspecting fan blade clearances in a fan casing (210) are presented. The method includes manually installing a bracket (230) that includes a laser module (235) and an inclinometer (236) to a fan rotor (215) that when rotated projects a laser beam from the laser module (235) to the fan casing (210) to determine a distance measurement between the laser module (235) and the fan casing (210) at multiple circumferential points around the fan casing (210). The distance measurement and circumferential position data is processed by a server (110) to determine a clearance distance between a fan blade (320) and the fan casing (210).
