摘要： A motorcycle like configured watercraft that employs a hull member to receive an engine and water jet nozzle means to propel the craft and the craft includes a seat area for a rider and steering means to control the direction of the craft. In addition, the craft includes a separate front ski member that has a water ballast chamber that may be connected to the steering means, and a pair of side skirts secured to the hull that contains water ballast chambers. The water ballast chambers designed to be capable of becoming quickly flooded when the craft is at rest to partially submerge the craft for ease of entry of the rider and means to cause rapid evacuation of the water in the chambers as the craft increases speed to raise the craft without restriction to its running and planing position.

摘要： Several embodiments of jet propelled watercraft that incorporate an arrangement for hydraulically pivoting the jet propulsion unit between a normal position and a raised position and for rotating the water inlet portion of the jet propulsion unit from a downwardly facing direction to an upwardly facing service position. Hydraulic motors are employed for achieving both motions and are actuated through a common circuit for achieving sequential movement. In one embodiment, the rotary hydraulic motor is formed integrally within portions of the housing of the jet propulsion unit to provide a compact assembly.

摘要： A race starting device for personal watercraft includes a thrust diverter connectable to the watercraft comprising a tube having an intake end adapted for alignment with the discharge nozzle of the watercraft, and a discharge end that is displaced from the intake end by a bent section of the tube to divert water flow from the water craft and thereby inhibit forward propulsion thereof until released. The diverter has the effect of deflecting the thrust from the watercraft and thereby inhibiting its forward propulsion. A quick release mechanism is also provided to releasably secure the thrust diverter to the watercraft. The release mechanism may be controlled by the watercraft operator to selectively release the device and allow the watercraft to thrust forwardly, leaving the starting device behind. Groups of the thrust diverters and quick release mechanisms may be provided on common frames for group starts. In one, a single quick release mechanism is provided to simultaneously start several racers.

摘要： A V bottom hull watercraft powered by a pair of jet propulsion units that are supported for pivotal movement about horizontally disposed pivot axes and rotary movement about a longitudinal pivot axis to rotate the water inlet openings and elevate them from a downwardly facing normal operating position and an upwardly facing service position. The water inlet openings are disposed so that they extend parallel to the sides of the V bottom. Steering nozzles are supported for pivotal movement at the discharge ends of the jet propulsion units and pivot about vertically extending axes that are not perpendicular to the water inlet openings so that no vertical thrust will be exerted on the watercraft hull when the steering nozzles are pivoted to effect steering.

摘要： An exhaust nozzle for a gas turbine engine comprising a duct 17(c) extending along an axis and having at a dowstream end thereof a mechanism for varying the geometry and area of the nozzle. The mechanism 28 comprises an axially translatable member 28 which has a face 29 extending in a direction transverse to the axis of the duct 17(c) against which pressurized gases flowing through the duct acts to balance out the loads on the flaps. A plurality of flaps 38,43 are spaced circumferentially around the axis of the duct. The flaps 38 are pivotally attached to the axially translatable member 28 and are provided with a cam follower 40 that co-operates with a cam 37. The cams 37 are fixed relative to the duct 17(c) and thereby defines the attitude of each flap 38 relative to the member 28. Seal plates 41 and 45 cover the gaps between adjacent flaps 38 and 43 to the seal plates 45. A plurality of struts interconnect the member 28 and the second flaps of the pivotal attachment of the flaps 43 to the flap 38. A set of flaps 47 are provided to provide fairing between the downstream ends of the member 28 and the flaps 43. In operation axial movement of the member 28 moves the flaps 38 and 43 to different positions.
