摘要： A pump frame (7) incorporates an upper opening (17), a lower opening (19) and a water passage (21) for connecting the two openings. To cause the lower opening (19) to be opened in water at a position adjacent a stern (1a) of a ship (1), the pump frame (7) is joined to a bottom (1b) of a ship (1). A pump casing (9) is secured to be stood erect above the pump frame (7). The pump casing (9) includes an impeller main shaft (33) stood erect. The impeller main shaft (33) is provided with an impeller (11) for sucking water from below the bottom (1b) through the lower opening (19) so as to pressurize the water. Water pressurized by the impeller (11) is jetted to a position behind the stern (1a) through a discharge pipe (13). As a result, the ship (1) is propelled. The foregoing water jet propulsion apparatus (5) enables sucking performance free from cavitation and excellent propelling performance to be obtained.

摘要： A nozzle having an undulating surface for enhancing the mixing of a primary flow with a secondary flow or ambient air, without requiring an ejector. The nozzle includes a nozzle structure and design for introducing counter-rotating vorticity into the primary flow either through (i) internal surface corrugations where an axisymmetric line through each corrugation is coincident with an axisymmetric line through the center of the flow passageway or (ii) through one or more sets of alternating convexities and cavities in the internal surface of the nozzle where an axisymmetric line through each convexity and cavity is coincident with an axisymmetric line through the center of the flow passageway, and where the convexities contract from the entrance end towards the exit end. Exit area mixing is also enhanced by one or more chevrons attached to the exit edge of the nozzle. The nozzle is ideally suited for application as a jet engine nozzle. When used as a jet engine nozzle, noise suppression with simultaneous thrust augmentation/minimal thrust loss is achieved.

摘要： A number of embodiments of watercraft having jet propulsion units contained within a tunnel in the hull and wherein the jet propulsion unit is pivotal about a first transversely extending horizontal pivot axis for bringing the jet propulsion unit through trim adjusted positions to an upward out of the water position. In addition, the jet propulsion unit is rotatable about a horizontal longitudinally extending axis so that its downwardly facing water inlet portion may be rotated upwardly for access through an access opening in the hull for servicing. In one embodiment, the jet propulsion unit is only rotatable about the horizontal longitudinally extending axis. A number of embodiments of rudder assemblies are also depicted supported by the steering nozzle for generating steering effects when the steering nozzle is not generating a significant steering effect and which may be pivoted to an out of the water position for protection when underwater obstacles are struck.
