Abstract:

This report contains the results of heavy and light displacement standardization trials conducted on USS OLIVER HAZARD PERRY FFG-7. Measurements of shaft rpm, shaft horsepower, shaft torque, thrust, propeller pitch, ship speed, ships heading, and relative wind velocity and direction were made throughout the speed range of 6 knots to full power. Heavy and light displacement standardization trials were conducted in the program control power mode utilizing single and twin engine modes of operation with single engine powering performance data comparing favorably with that of twin-engine. Heavy displacement twin-engine standardization trials were undertaken comparing design, over-design, and under-design pitch. Speed attainable at rated power for single and twin auxiliary propulsion units was determined. Very poor directional controllability was experienced with auxiliary propulsion units in operation.
