Abstract : Dynamic measurements were conducted to acquire data for the development of a mathematical model of the undercarriage of a S-70B-2 (Seahawk) helicopter. The principal measuring instrumentation consisted of LVDT's and ultrasonic transducers. This memorandum discusses a Ranging Ultrasonic Transducer which was developed to overcome the inherent and excessive recovery time delay of the ultrasonic transducers when subjected to out-of-range distance operations during the flight trials.
