Abstract
1375090 Craft with secondary waterjet duct BOEING CO 22 Dec 1972 [20 March 1972] 59455/72 Headings B7A and B7V A waterjet propulsion assembly comprises a submerged primary nozzle 24 which discharges a waterjet into an unconfined space beneath the hull of a marine craft and a duct 42 mounted on the craft at a predetermined location aft of the primary nozzle. The duct has an inlet 40 which receives a portion of the primary waterjet and a certain amount of ambient water from the unconfined space. In the embodiment shown the secondary waterjet nozzle 44 is located aft and above the inlet 40.
