SYSTEM AND METHOD FOR INSPECTION OF STATOR VANES
First Claim
1. A method, comprising:
- rotating an image recording assembly removably coupled to a rotary component of a compressor of gas turbine engine around a shaft of the gas turbine engine; and
recording images of stationary components disposed circumferentially around the shaft, without removal of a housing of the compressor.

Abstract
Embodiments of the invention include an inspection system to inspect internal components of a compressor of a gas turbine engine. The inspection system includes an image recording assembly having one or more image recording devices, light sources, storage devices, and power supplies. The image recording assembly may be inserted into a compressor without removal of the compressor housing or disassembly of the compressor. The image recording assembly may be removably coupled to a rotary component of the compressor, e.g., a rotor blade, and used to record images of stationary components, e.g., stator vanes, of the compressor. The images may be inspected to identify wear and/or defects in the stationary components, e.g., stator vanes
