摘要： 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

摘要： A method for monitoring stress on a wind turbine blade during loading is disclosed. The method includes capturing multiple images at respective locations of the blade. The method also includes measuring temperature at the respective locations based upon captured images. The method further includes calculating stress applied on the blade at the respective locations based upon the measured temperature. The method also includes calculating stress applied on the blade at the respective locations based upon the measured temperature. The method further includes comparing the calculated stress with respective theoretical stress in a finite element model to predict lifetime of the blade. The method also includes alerting an operator in event that the calculated stress at one or more of the respective locations is above a pre-determined limit.

摘要： A gear inspection system and method for a gearbox, wherein an image acquisition unit is oriented proximate the gearbox with a field of view of a section of the gears. The image acquisition unit obtains images of a gear tooth and corresponding contact pattern. In one embodiment a processing unit transforms the images to a gear tooth model so that the gear tooth image and contact pattern image matches the model gear tooth. Metrics are computed for the contact pattern, and based on threshold values, a determination is made as to whether the gearbox is acceptable.
