Innovative Foreign Object Damage (FOD) Detection and Identification Technology for Military Turbine Engines

There are four milestone categories CV will focus attention on for this proposal; „X Implementation of an optical phase sensor. „X Addition of micro-acoustic wide-band sensors to better monitor the stators. „X Performing FOI testing on the CV rotor Kit or blisk based rotor kit available „X Software development. An optical phase sensor will be incorporated into the basic instrumentation which includes vibration monitoring, and will require developing an on-wing variant of the existing CV400 key phaser product line. This will be the instrumentation basis for the combined phase and magnitude approach to FOI detection. CV equipment and software has been used for phase analysis throughout industry for many years. Cognitive Vision¡¦s VibeSurvey software is the standard used by the U.S. Navy and other navies for the GE LM2500 fleet, and BalancePro is a standard for commercial aviation, as well as the KC10 fleet and other Air Force aircraft. Both provide real-time phase and magnitude information to the operator/analyst. Cognitive Vision employs two different methods of transfer function and phase calculation, and study/analysis will be needed to determine the most appropriate methodology.
