Hydrojet Ducted Propulsion System: Impeller Induced Vibratory Pressures and Performance Characteristics

摘要

A vortex-line theory developed for an impeller in a long duct was used to optimize the design of a Hydrojet impeller. A model Hydrojet with this impeller was instrumented for pressure field and impeller performance measurements. Fluctuating pressures were high near impeller but attenuate to
