Abstract
THIS PROPOSAL IS FOR DEVELOPMENT OF SENSORS FOR TURBOMACHINERY BLADE CLEARANCE AND TIME OF ARRIVAL, BASED ON NOVEL EDDY-CURRENT SENSING TECHNOLOGY ORIGINATED BY VATELL CORPORATION. THE NEW SENSING TECHNOLOGY MAY RESULT IN SIGNIFICANT BANDWIDTH IMPROVEMENTS FOR BOTH CLEARANCE AND TIME MEASUREMENTS. PROTOTYPE SENSORS RATED FOR 200 GEGREES CENTIGRADE WILL BE FABRICATED AND TESTED ON THE FIRST STAGE FAN OF A PRATT & WHITNEY JT15-D TURBOJET ENGINE IN THE VIRGINIA TECH TURBOMACHINERY LABORATORY. EXPERIMENTAL DATA WILL BE USED TO ESTABLISH EMPIRICAL VALUES IN A MATHEMATICAL MODEL OF THE RELATIONSHIPS BETWEEN SPEED, CLEARANCE AND SENSOR SIGNAL AMPLITUDE. TEST RESULTS WILL BE REPORTED AND PROTOTYPE SENSORS WILL BE DELIVERED TO THE AIR FORCE FOR USE OR TESTING.
