Optical Instrument for the Assessment of the Structural Integrity of Complex Systems

"Vibration and performance monitoring provide important information for turbine health engine health management. We have outlined a concept to develop an optical sensor that can quantitatively measure the vibration parameters of turbine engine componentsduring operation. Based on vibration monitoring, the proposed instrument can identify the particular signatures of individual engine components. This information can be used for health monitoring of operating machinery as well as to study prototypeengine components. During Phase II, we will perform an extensive analysis of the proposed instrument and its performance, carry out its design, and by constructing a prototype system, demonstrate real-time operation both in laboratory and fieldconditions. Careful attention will be paid to developing robust system that can operate under the harsh thermal and vibratory conditions of an operating turbine. We will work closely with engineers at a leading engine manufacture and test facility todevelop a prototype design commensurate with the industry's measurement needs and compatible with existing engine access constraints."
