USS AVENGER (MCM 1) Standardization, Locked Shaft, and Trailed Shaft Trials
Abstract
Standardization, Trailed Shaft, and Locked Shaft Trials were conducted on USS AVENGER (MCM 1) to develop baseline speed and powering characteristics for the MCM 1 class minesweepers. The trials were performed off the west coast of St. Croix, U.S. Virgin Islands from 19 to 22 June 1989 as part of NAVSEA First of Class Performance Trials. During the Standardization Trial a maximum speed of 13.92 kn at 181.7 r/min average shaft speed was achieved with the propellers at nominal 100% of design pitch. To achieve this speed, AVENGER required 2,050 total shaft horsepower (1,530 kW), with 59,300 ft-lbf total torque (80,300 N-m) applied to the shafts. The maximum speed achieved during the Locked Shaft Trial was 9.13 kn with the port shaft driving the ship at a shaft speed of 167.2 r/min. At this speed the AVENGER used 970 hp (720 kW) and 30,400 ft-1bf of torque (41,200 N-m) on the driving shaft. During the Locked Shaft Trial, the pitch on the port propeller was at nominal 100%, while the pitch on the locked starboard shaft propeller was nominal 15%. For the Trailed Shaft Trial a maximum speed of 10.34 kn was achieved at 168.5 r/min shaft speed on the driving port shaft. This speed was accomplished with 980 hp (730 kW) and 30,300 ft-1bf torque (41,100 N-m) on the driving shaft. During the Trailed Shaft Trial nominal 100% pitch was used on the port propeller with the starboard propeller trailing at nominal 1 10% pitch, Baseline standardization, trailed shaft, and locked shaft curves are also developed for the AVENGER in this report.
