    摘要: A sliding-blade water jet propulsion apparatus has an oval-shaped chamber and a water channel extending generally tangential to the chamber with a cylindrical rotor rotatably mounted eccentrically in the chamber. The rotor has at least two rectangular blades slidably mounted in slots extending through the cylindrical rotor in mutually perpendicular relation and each blade is independently movable relative to the other in a radial direction. Each blade has a guide element extending from opposed sides and through the opposed end walls of the rotor which are slidably received in guide grooves in the chamber end walls. The guide elements traveling in the guide grooves cause the blades to extend and retract radially with their outer ends following the inner periphery of the chamber side wall and a portion of the water channel with a constant clearance. In one embodiment, the rotor is rotated by a working gas entering the chamber and upon expansion effectuating gas pressure on one side of the blades which causes water in the water channel to be expelled by the opposite side of the blade without substantial mixing of the gas with the water, and as the rotor rotates more water is drawn into the water channel. In another embodiment, the rotor is rotated by an external power source connected to the shaft of the rotor rather than by a working gas.

    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.

    摘要: A foiled grating is provided for use with a jet-powered personal watercraft. The grating is adapted to be secured substantially across the intake opening in the bottom of the craft's hull and includes a foil and at least two substantially parallel bars oriented longitudinally within the intake opening. The foil is supported by the bars and positioned so as to divide a section of the intake channel into upper and lower portions to direct the intake water flow for a more even flow to the craft's jet pump.

    摘要: An adjustable two-dimensional nozzle is disclosed in which simplified control means are located away from the flow of gasses through the nozzle. The nozzle includes a movable frame located outside of fixed sidewalls and has pivotally attached thereto a pair of upstream or converging nozzle flaps. Upstream edges of the upstream flaps are attached to the movable frame such that the flaps pivot about axes extending substantially perpendicular to the longitudinal axis of the nozzle. Downstream or diverging flaps are attached to the downstream edges of the upstream flaps such that these flaps also pivot about axes extending substantially perpendicular to the longitudinal axis of the nozzle. A cam member extends between each of the movable frames and each downstream flap to control the angular variations of the flaps during movement of the frame. The flap arrangements are symmetrically arranged with respect to a plane passing through the longitudinal axis of the nozzle, such that translational movement of the frames will alter the cross-section of the nozzle in a symmetrical manner with respect to the plane. If the frame is rotated about its pivot attachment, the nozzle flaps will be asymmetrically adjusted and may be utilized to vector the thrust of the gasses emanating from the nozzle.

    摘要: The throat configuration of a converging-diverging nozzle (16) is varied by defining a throat area (18) of the nozzle by a plurality of impinging ion beams arranged symmetrically around the throat area of the nozzle and directed toward a central point (34) within the aforementioned throat area. Each of the ion streams is independently controlled so as to permit variation in the symmetry of the throat area as well as the size thereof, and permit deflections of the fluid flow paths as well as changes in, for example, a thrust generated by a fluid stream passing through the nozzle.

    摘要: The marine jet propulsion unit of this invention, in preferred form, has a pair of laterally adjacent blade carriers, each having a vertical outer surface movable in a horizontal orbit and to which blades are fixed that project edgewise outwardly. Each blade has a surface facing in the direction of its orbital movement that is concavely curved along its height. The two blade carriers, at opposite sides of a fore-and-aft extending vertical plane of symmetry, are driven in opposite orbital directions such that each has a driving portion remote from the plane of symmetry that moves rearward in an acceleration channel and has an opposite forwardly moving portion adjacent to the plane wherein its blades are interleaved with those of the other. Water entering a forward intake is guided in two streams, one to the front end of each acceleration channel, and the rear end of each acceleration channel is communicated with a discharging outlet nozzle.

    摘要: Hydraulic jet propulsion apparatus having steering deflectors which are hydraulically balanced which operate against a seal to reduce spillage and to reduce jamming ans which will provide a smooth contour for the flow of water while not restricting the cross-sectional area of the jet stream. The apparatus also provides a reversing duct which is operable to intercept the jetstream, downstream of the steering deflectors so that the jetstream is divided into two streams the relative proportions of which depend upon the operation of the steering means each stream being turned while in the duct through an angle in excess of 90 degrees to emerge in diagonal directions respectively forward-to-port and forward-to-starboard so as to produce a reverse thrust with steering dependant on the relative proportions of flow in the two streams.

    摘要: A control system for water jet ship propulsion apparatus of the type having reverser bucket apparatus which is selectively and controllably movable into the path of a driving jet to reverse the thrust of the jet. The invention is characterized in the use of plural potentiometers connected to a single control throttle, one of the potentiometers acting to control the driving engine for the propulsion apparatus and the other acting to control the position of the reverser bucket apparatus. Both potentiometers employ shorted sections such that the driving engine will run at idle speed on either side of a neutral setting while the reverser bucket apparatus is moved from a fully-retracted to a fully extended position for reverse thrust. Once the reverser bucket apparatus reaches one of its two extreme positions, engine speed can be increased with increased thrust. In the engine idle region, reverser bucket modulation of the jet stream can be effected to give forward and reverse boat speed control at the engine idle setting.
