Analysis of vibratory problem which occurred in propulsion units of World War II C4-S-A4 vessels; mode of vibration was longitudinal, in which propeller excited propulsion gears in fore and aft direction, and was resolved by substitution of five-bladed propeller for four-bladed unit; propulsion unit consists of nested, double reduction gear driven by cross compound H-P and L-P turbines, nominally rated 9000 shp at 85 turns.
