METHODS AND APPARATUS FOR MEASURING AXIAL SHAFT DISPLACEMENT WITHIN GAS TURBINE ENGINES

摘要

In some embodiments, an apparatus includes a target member, a sensor and a mounting assembly. The target member is coupled to a shaft that is disposed within an engine housing and that rotates about an axis. The target member includes a target surface that is substantially normal to the axis of rotation of the shaft. The sensor is configured to produce a signal associated with a distance between a sensor tip and the target surface. The mounting assembly is coupled to the sensor and the engine housing, and is configured to adjust the distance between the sensor and the target surface.
