Powering Predictions and Propeller Disk Wake Survey Data for the USNS HAYES T-AGOR 16 Represented by Model 5285.
Abstract
The USNS HAYES (T-AGOR 16) is an unconventional catamaran hull and is the first catamaran employed for oceanographic research. This vessel provides a stable, quiet, self-sufficient, and maneuverable platform for obtaining oceanographic data and working with a submersible. Processing information on board can be accomplished at three different speed conditions: cruising, normal operation from 5 to 15 knots; creeping, underway at 2 to 4 knots; and quiet operation, ship dead in the water. An investigation was undertaken to determine the feasibility of replacing the Mobile Noise Barge (MONOB) with the HAYES. MONOB is used for determining acoustical signatures of various marine vehicles. Experiments were conducted on a model representing the HAYES. Resistance propulsion, towing, and wake survey experiments were performed on Model 5285 with a bow foil. Results of the propulsion experiments showed the HAYES attaining a 12.4 knot speed at a delivered power of 2,200 horsepower (1,164 kilowatt) with the design propeller pitch. Towing predictions showed the HAYES could tow an array with a resistance of 29,000 pounds (129,000 newtons) at 10 knots and resistance of 9,000 pounds (40,000 newtons) at 12 knots. The wake survey experiments provided data to enable the propeller designer to design a fixed pitch propeller that will replace the existing controllable pitch propeller.
