摘要： A waterjet propulsion pump (14) is mounted in an opening in a fully submerged intermediate transom (12) located forward of the stern transom (11) and at the aft end of a dependent structural pod (15) on the hull bottom with the pump discharge nozzle (30) lying aft of the intermediate transom. A steering nozzle (50) is mounted on the discharge nozzle (30) for pivotal movement about an axis that lies in a vertical plane. At least one reversing deflector (100 or 300 and 400) is mounted for pivotal movement about an axis that is perpendicular to the vertical plane. A rotatable steering shaft (70, 270) operated by a steering actuator located with the hull (140 or 340) is coupled to the steering nozzle (50 or 250). A hollow reversing shaft (90, 290) is received telescopically over a portion of the steering shaft and is translatable axially relative to the steering shaft by a reversing actuator (150, 350) located within the vessel hull. A mechanical linkage (110, 310 and 118, 318) coupled between the reversing shaft and the reversing deflector pivots the reversing deflector between an inactive position and an operative position. Fairings (25, 26, 27) fair to the lines of the pod and to each other cover the sides and bottoms of discharge nozzle, steering nozzle and reversing deflector, and the steering and reversing shafts.

摘要： An impeller (22) for a marine waterjet propulsion system has blades (44) that are configured to reduce cavitation, vibration, noise and physical damage to the major components of the propulsion system or host vessel of installation. The leading edge (52) of each blade of the impeller is skewed forwardly over at least the outer 70% of its span, the forward skew being maximum at the tip (56) and being not less than 35° and preferably not less than 50°. The impeller has a blade area ratio of not less than 1.5. The chord lengths of each blade increase progressively from the point of minimum skew to the tip, resulting in reduced loading in the cavitation critical region. A partial or full tip band may be affixed to the blade tips.

摘要： A waterjet steering and reversing apparatus has a steering nozzle mounted aft of the exit nozzle for pivotal movement about a steering pivot axis that lies in a vertical plane and a reversing deflector that is mounted for pivotal movement about a reversing pivot axis for movement between an inactive position clear of a water jet discharged from the steering nozzle and an operative position in which the water jet impinges on a surface that deflects the water jet to a direction having a forward vector. The reversing pivot axis is perpendicular to the vertical plane and spaced apart from the steering pivot axis. A rotatable steering shaft is coupled at its lower end to the steering nozzle, is coaxial with the steering pivot axis, extends upwardly through an opening in the hull, and has an upper end portion located within the hull. A hollow reversing shaft received telescopically over a portion of the steering shaft is translatable axially relative to the steering shaft. A steering actuator received within the vessel hull and coupled to the steering shaft imparts rotation to the steering shaft. A mechanical linkage coupled between the reversing shaft and the reversing deflector pivots the reversing deflector between the inactive position and the operative position upon axial translation of the reversing shaft relative to the steering shaft by a reversing actuator received within the hull.

摘要： A blade of a built-up marine propeller is balanced by forming an open cavity of a predetermined size at a predetermined location proximate to the blade tip, conducting a spin-balancing test in which the blade being balanced and a calibration blade are assembled diametrically opposite each other on a dummy hub to form a simulated two-blade propeller, determining from the test the weight that must be added to the blade to balance the simulated propeller, and affixing a balance member of a predetermined weight in the blade cavity. A cover plate is secured in the cavity opening of the blade in sealed relation, and the external surface of the cover plate is ground to make it fair to the profile of the portion of the blade face adjacent the cavity opening.

摘要： An oil distribution box for a marine controllable pitch propeller of the type having a main hydraulic servo within a hub for controlling the pitch of propeller blades rotatably carried by the hub and including a directional valve actuated by a tubular valve rod extending through the propeller shaft from the oil distribution box comprises an outer stationary housing, a shaft received within the housing and coupled to the propeller shaft and an auxiliary servo chamber cylinder coupled to the shaft. A piston received in the servo chamber is coupled to the valve rod. Oil is supplied to the valve rod through an elongated annular supply chamber defined between the shaft and the valve rod by spaced-apart seals, a port in the valve rod opening to the supply chamber, a port in the shaft opening to the supply chamber and a journal clearance seal between the housing and shaft in register with the port in the shaft. Oil is supplied to the servo chamber selectively to the chamber sections on the respective opposite sides of the piston through, for each section of the servo chamber, a supply-return passageway in the cylinder communicating with the servo chamber, a passage in the housing, and a journal clearance seal between the housing and the servo chamber cylinder in register with the passage and the passageway. A normally closed pilot-operated check valve in each passageway isolates the servo chamber from the clearance seals except when oil is supplied to the auxiliary servo to produce a pitch change.

摘要： An inboard servo for a controllable pitch propeller of the force rod type comprises a feedback device comprising a feedback ring located externally of the propeller drive shaft, affixed to the force rod for rotation and axial translation therewith and having a planar surface perpendicular to the propeller drive shaft axis, and a distance-measuring device for substantially continuously detecting the position of the ring, and therefore the position of the force rod. The distance-measuring device directs a high frequency pulsed signal onto the ring surface from a fixed position spaced apart therefrom, detects the signal as it is reflected by the ring surface from a fixed position spaced apart therefrom, and processes the directed and reflected signals to produce a signal indicative of the position of the ring surface based on the time difference between the pulses directed onto the ring surface and the pulses reflected from the ring surface.

摘要： A controllable pitch marine propeller includes a hub body having a forward section provided with holes for bolts and locating and torque pins and a frontal surface that mates with a hub flange and an internal flange that defines an annular cavity and receives a cup-shaped cross-head. A hub flange and propeller shaft assembly comprises separate hub flange and shaft members joined by at least one weldment formed in a tapered weld cavity and protected by a liner shrink-fitted on the perimeter of the hub flange and a removable plate sealed to the hub liner and the shaft liner.
