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.
89	Control method and control system for a controllable pitch marine propeller	US10573934	2004-09-06	US07473076B2	2009-01-06	Hans-Gunther Rosenkranz; Martin Robson
A control method and system for a controllable pitch marine propeller including operating modes comprised of a maneuvering mode and a cruise mode and check modes comprised of an engine check mode and propeller check mode. The cruise mode provides for wide open throttle acceleration and power stop. Smooth transition sub-modes are provided for providing smooth transition between cruise mode and maneuvering mode and vice versa. The system operates by a lever (28) which controls a pitch control unit (10) which in turn controls engine speed and also the pitch of propeller blades (12) of propeller (14). Thus, dependent on the position of the control lever (28) in either maneuvering mode or cruise mode, an appropriate engine speed and propeller pitch is selected automatically for driving a watercraft.

92	Propeller	US09630325	2000-07-26	US06406264B1	2002-06-18	Robert D. Paulus
A propeller that has curved vanes attached to the blade tips and to the blade body. The curved vanes at the blade tips act as a nozzle. However, because the “nozzle” is attached to the propeller blades, there is no need to modify the boat motor to accommodate it. In this design, the nozzle turns with the propeller. A full blade ring or guard can be formed and attached to the blades, if desired. This ring not only enhances the nozzle effect, it also protect people and items from getting drawn up into the blades of the propeller. This improves propeller safety as well. The propeller blades can have a number of different vane configurations. Moreover, there is a design that allows for variable pitch of the blades.
93	Partially immersible propeller	US896161	1997-07-17	US5803776A	1998-09-08	Petr Petrovich Slynko
The propeller comprises a propeller shaft mounted so that its position in relation to the ship's hull can be varied both at stopovers or in transit. The propeller shaft carries propeller blades of such a configuration that, while going into the water, they position their face sides normally to the longitudinal center plane of the ship. According to the invention the propeller blades can change position relatively to the longitudinal center plane or to the midship section plane or simultaneously to both the planes, thereby increasing speed, maneuverability, efficiency, and safety.
94	Apparatus for detecting the pitch of a marine controllable pitch propeller	US339725	1989-04-18	US4906213A	1990-03-06	William F. Esthimer
The pitch of a marine controllable pitch propeller is detected by a motion/DC current transducer in the propeller hub. Circuitry rotating with the propeller shaft converts an AC power signal to DC for energization of the transducer and converts a DC output signal from the transducer to AC. The AC power and output signals are transferred from the rotating circuit to a stationary circuit in the vessel hull by rotary transformers. There are no contacts between relatively moving parts of the transducer or rotary transformers, thus ensuring long life for the pitch detection system.

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.
96	Device in fluid pressure generators	US777781	1985-09-17	US4648788A	1987-03-10	Philip Jochum
A device in fluid pressure generators comprising an annular casing which is peripherally mounted and driven in a through-flow channel. The inner face of said annular casing forms part of the wall of the through-flow channel. The annular casing is provided with a number of propeller blades which extend radially inwardly into the through-flow channel and which are rotationally mounted on their individual pin shafts by means of which propeller blades the magnitude of the thrust may be altered in a continuous manner and the direction of operation of said thrust in the through-flow channel be reset.
97	Propeller blades	US826753	1977-08-22	US4150914A	1979-04-24	Stig O. Karlsson
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.

In a controllable pitch propeller assembly, a threaded and split bearing ring engages an internally threaded radial bore in the hub of the assembly. A plug for expanding the bearing ring is provided to interlock the threads of the ring with those of the radial bore in the hub.
99	Propeller pitch indicator	US41034373	1973-10-29	US3895883A	1975-07-22	PEDERSEN JAMES MILLER
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.
100	Controllable pitch tunnel thruster for ship positioning	US19203671	1971-10-26	US3759211A	1973-09-18	KUNTZ F
A ship is described having a transverse thruster arranged in a tunnel running athwartship preferably, for example, near the bow so as to enhance steering or for slowly moving the ship sideways. The thruster comprises a movable portion of the tunnel wall having inwardly extending blades. The movable wall and blades are driven together in rotation about the axis of the tunnel so that the blades propel water therethrough. In addition, the pitch of the blades relative to a plane transverse to the tunnel axis is controllable for continuous variation of thrust from a maximum in one direction to a maximum in the opposite direction. Means are provided for controlling pitch of the blades while the thruster is rotating.
