USS SCOUT (MCM 8) Results of Standardization, Locked Shaft, and Trailed Shaft Trials
1992
Klitsch, Michael L. | Liu, Wayne P.
Standardization, locked and trailed shaft, acceleration and deceleration, and fuel economy trials were conducted on USS SCOUT (MCM 8) to evaluate the performance of the ship equipped with Isotta Fraschini diesel engines and Voith fluid drive couplings. The results of the acceleration and deceleration trials and the fuel economy trials are the subject of separate reports. Standardization results from SCOUT showed a maximum speed of 14.21 kn achieved with an average shaft speed of 175.2 r/min, a total shaft torque of 67, 800 lb-ft (91,900 N-m), a total shaft horsepower of 2,260 (1,690 kW), and a displacement of 1,293 tons (1,314 t). The average propeller pitch for this condition was 110%. This 110% pitch was found to be the optimum driving pitch as it was the only condition where maximum torque and shaft speed could both be achieved.
