Gas turbine stator segment anti-rotation lock

摘要

An anti-rotation lock (61) for preventing circumferential movement of a stator segment (30) in relation to a split case (32) to which it is mounted is disclosed. A racetrack shaped pocket (62), disposed within the case (32) and proximate the stator segment (30), is suitably sized to receive a lug (64) and a spring pin (66). The lug (64) is received in the pocket (62) and protrudes radially inward from the case (32) and is engagable by the stator segment (30), thus preventing circumferential movement with respect to the case (34). The spring pin (66) is received adjacent to the lug (64) and compressively retains the lug (64) in the pocket (62).
