The testing conducted and reported herein was an 18 month experimental program to determine the worth of an electrostatic probe and associated electronics as an indicator of engine health. The program consisted of laboratory tests, gas turbine engine probe location tests, particle injection tests, probe signature determination, development of data recording techniques, accumulation of data during durability testing of T56 or TF41 engines and any other opportunistic gas turbine engine test. The electrostatic probe demonstrated some capability to detect engine distress in TF41 and T56 engines however, this program did not develop a reliable satisfactory engine failure detector system. Additional effort will be necessary to assure this. Author
