摘要： A propeller and related method for the adjustment of the fluid-dynamic pitch of the propeller blades are described. The propeller is provided with at least one rotatable blade pivoted to a propeller cylindrical casing (3), a hub (2) adapted to be coupled to an engine and mounted within the propeller casing. The hub (2) is rotatable with respect to the propeller cylindrical casing (3), or vice versa, for at least one non-zero angular interval (a) for the adjustment of the fluid-dynamic blade pitch. Moreover, the hub comprises at least one contact surface (20, 21 ) movable between at least one direct or indirect disengagement position, and at least one direct or indirect engagement position with at least one respective abutment (10) which defines at least one limit stop of the angular interval (a). The limit stop abutment (10) comprises at least one region of at least one movable element (11 ) arranged in at least one seat (30) of the propeller cylindrical casing (3) for modifying the limit stop abutment position of the at least one angular interval (a). The propeller is characterized by comprising means (51, 52) to adjust the position of the at least one movable element (1 1 ), in one or more discrete intervals for the modification of the position of said at least one limit stop abutment (10) of the at least one angular interval (α).

摘要： The main propulsion and drive system of a merchant vessel such as a freighter or tank vessel, or a military vessel is supplemented by an auxiliary propulsion and drive system that includes at least one, but preferably a pair of auxiliary propellers that flank the main propeller at port and starboard positions and each of which are attached via a drive shaft through a gear train, which can optionally include a clutch mechanism, to an auxiliary motor or motors. In order to reduce the drag when the main propeller is disabled, segments of a wake field modifying propeller duct are mounted for repositioning to form at least a partial housing or cowling that diverts the water over the exterior surface of the duct and minimizes contact with the stationary blades of the main propeller as the vessel moves through the sea when powered by the auxiliary propulsion system.

摘要： The invention relates to a rotor (1) through which a fluid flows in a main direction of flow (H) and which is provided with at least one rotor blade (4), said rotor blade being arranged in such a way that it can rotate about a rotor axis. The rotor blade (4) extends away from the axis of rotation (2), into the fluid, at least in sections. The rotation (D) of the rotor blade (4) about the axis of rotation (2) in a predetermined direction of rotation produces a propulsive thrust in the opposite direction to the main direction of flow, or a torque is produced about the axis of rotation as a result of the flow. The aim of the invention is to reduce the trailed tip vortex at the end of the rotor blades of rotors of this type and therefore to reduce the fluidic losses and flow noise. To this end, the rotor blade (4) extends in at least two partial blades (5, 6) at a set distance from the axis of rotation and forms a loop. One partial blade (5) extends in the direction of rotation (D) in relation to the rotor blade, at least in one area close to the rotor blade. The other partial blade extends in the opposite direction to the direction of rotation (D) in relation to the rotor blade (4), at least in one area close to the rotor blade (4). The two partial blades (5, 6) are interconnected in one piece at their ends so that they encompass a loop surface (12) through which the fluid flows, said loop surface extending essentially crosswise to the main direction of flow.

摘要： 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.

摘要： An improvement in a variable pitch propeller to allow replacement of propeller blades under water without water intruding into the mechanism in the propeller hub and without a substantial quantity of oil leaking to the surrounding water. The propeller comprises a number of turnable propeller blades (2) which are each removably attached to a rotatable crank disk (3) and for each propeller blade there is provided a first seal (5) between the hub (1) and the propeller blade root (2a), a second seal (6) between the hub (1) and the crank disk (3) and a by-pass valve (7) passing the second seal (6). the valve (7) is spring biased to remain in a closed position when the propeller blade (2) is removed. When the propeller blade (2) is secured in place the first seal (5) is operative and when the propeller blade is removed, the second seal (6) is the operative one together with the valve (7).

摘要： The rotational speed of a screw propeller mounted on a propeller shaft of a ship is correctively increased or decreased by locally heating the back or face side of each blade of the propeller along a plurality of paths substantially parallel to and inward from the trailing edge of the blade in a region from a radial position about of 0.5 R to the blade tip, where R is the tip radius, particularly from 0.6 to 0.7 R, and cooling the parts thus locally heated thereby to form wash-back in each blade between the trailing edge and the heating paths thereof as a result of angular deformation accompanying plastic deformation due to the heating and cooling and thereby to decrease or increase the effective pitch of the propeller.

摘要： 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.
