Abstract : This paper presents a theoretical investigation of a water-augmented turbofan engine, one in which large quantities of sea water are injected into the fan duct section. Results indicate that up to three or four times dry thrust and propulsive efficiency are obtained depending on vessel speed, fan pressure ratio, and amount of water injected. Optimum water injection velocity is investigated. Deviations from thermal and dynamic equilibrium in the mixing processes are investigated with respect to their effect on overall performance.
