THE DTMB MARK I MEASUREMENT SYSTEM FOR CABLE-TOWED BODIES,
Abstract
An electronic system, designated the DTMB Mark I Measurement System, was developed to measure certain hydrodynamic characteristics of cable-towed bodies during steady-towing conditions. The quantities measured are body roll, pitch, and depth, cable tension and angle (at the body and ship), and speed. The accuracy of measurement is limited by the accuracy of the transducers and is generally about one percent of full scale. One unique feature of the system is a remotely controlled electricalcalibration network that permits calibration of the transducers while the system is being towed. A second unique feature is the use of a magnetic-tape recorder in conjunction with electronic counters to perform analogto-digital conversion. (Author)
