摘要： An inboard servo for a controllable pitch propeller of the force rod type comprises a feedback device having at least two feedback rods connected to the piston and extending through the cylinder end wall and an output ring connected to the rods. An emergency lock-up includes at least two threaded locking rods fastened to the cylinder and passing freely through holes in the feedback ring, each of which receives one or more nuts that can be threaded along the rod for engagement with the feedback ring to lock the piston in a desired position.

摘要： The present invention relates to propeller blades which are mounted in a rotatable propeller hub and pivotable in the same by means of inner shafts with axes substantially radial to the axis of rotation of the hub and countersunk in said hub and located inside an outer peripheral edge of the same. The propeller hub is positioned in an shroud means, a tunnel or similar with a surrounding wall, which is substantially circular and concentric to the axis of rotation of the hub. The propeller blade has a blade vane with an outer edge with portions shaped as peripheral arcs concentric to the hub axis and having a play to the surrounding wall which is smaller than the necessary radial movement which is required for the lifting of said shaft over the peripheral edge of the hub when the propeller blade has to be demounted from the hub. According to the invention the peripheral arcs of the outer edge are limited to the front and rear portion of the edge while the centric portion extends inside the circle forming said arc shaped portions so that a play is formed between this centric portion and the wall of the shroud means when the blade is pivoted to a position in which the same is substantially parallel to the axis of the shroud. This play allows the blade to be moved in radial direction so that the shaft can pass said peripheral edge of the hub. With this arrangement a demounting and mounting of the propeller blade in axial direction is possible without removing the hub from the shroud means and without the negative influence on the propeller efficiency from an enlarged all over play between the outer edge of the blade and the wall of the shroud means.

摘要： Indicator for a marine controllable pitch propeller mounted on solid or hollow tailshaft. Indicator is free of inaccuracies arising from tailshaft compression and lost motion between linkages. Components of indicator that are susceptible to wear are generally accessible for servicing without dry-docking vessel. Indicator has sensor connecting electrical position transducer to a component within the propeller hub, which component moves in response to pitch change. The transducer can be mounted within the hub, or on the tailshaft externally of the hub, electrical output from transducer being transmitted from tailshaft through a rotary contact unit using conducting rings engaged by brushes. Galvanometer calibrated in pitch reflects current from transducer which is dependent on pitch of propeller. Sleeve conduit provides clearance for output from sensor through bearing sleeve without boring tailshaft.

摘要： A propeller includes a plurality of propeller blades. Each blade has an adjustable drag coefficient. A plurality of actuators adjusts the drag coefficients of the propeller blades. A controlling unit controls the plurality of actuators such that the drag coefficients of each propeller blade is adjusted according to a pattern that is dependent upon the rotational angle of the particular propeller blade so that the drag of each propeller blade is maximized at the same point through a course of revolution and minimized throughout the remainder of that revolution.
