Abstract:

The need has developed for a reliable paravane towing technique for use by surface ships in connection with an Acoustic Torpedo Countermeasure Investigation. The problem was to evaluate two independent Swallow-Tail towing techniques and determine their ability to provide a stable platform on which to mount acoustic torpedo countermeasure equipment. Two such paravanes were tested on the USNS MIZAR T-AGOR-11 enroute from Bermuda in May 1965. The Boeing Company, Vertol Division, and the Braincon Corporation paravanes were individually designed and tested. The Vertol paravane exceeded the performance specifications of 8 knots, 30 degrees span angle and met the towing duration specification of 50 hours without adjustment. The Braincon paravane was able to tow at 8 knots but was unable to achieve the required span angle and towing duration. A comparison of data taken at sea on the two units indicated Vertols technique to be very suitable to the above-mentioned application. However, the Braincon technique cannot be recommended at this time.
