    摘要： A method of controlling the angular orientation of at least one variable fluidfoil 52. The method comprises the steps of:
    a) receiving detected fluidfoil angular orientation data for the at least one fluidfoil 52;
    b) receiving a fluidfoil angular orientation demand;
    c) generating a modified angular orientation demand by modifying the fluidfoil angular orientation demand before it is used to control adjustment of the at least one fluidfoil 54, the modification being performed using the detected fluidfoil angular orientation data; and
    d) outputting the modified demand and controlling the at least one fluidfoil 54 angular orientation in accordance with the modified demand.

    摘要： A hydraulic fluid transfer coupling has a stator, a first coaxial rotor, and a second coaxial rotor. The first rotor is radially inwards of the stator, the second rotor is radially outwards of the stator, at least part of the first rotor axially overlapping with the stator, and at least part of the second rotor axially overlapping with the stator. The first rotor carries one or more first rotating fluid lines, and the second rotor carries one or more second rotating fluid lines. The stator carries one or more first static fluid lines and second static fluid lines. Each pair of a first rotating fluid line and the corresponding first static fluid line are fluidly coupled and each pair of a second rotating fluid line and the corresponding second static fluid line are fluidly coupled. Hydraulic fluid is transferable between each static fluid line and the corresponding rotating fluid line.

    摘要： A blade angle feedback system is disclosed for use with a propulsion system (12) having a plurality of angularly adjustable blades (14), wherein each of the blades (14) has an axis of rotation BCL and is rotatable about the axis of rotation through a plurality of blade angles. The system includes a mechanism (24) for indicating blade angle position of each of the sensed blades (14). The mechanism for indicating (24) is movable through the plurality of blade angles with the blades (14), wherein the mechanism for indicating (24) has a plurality of identities depending on and indicative of the blade angle. Mechanisms for designating (28) a plurality of reference positions on the blades (14) of the propulsion system (12) and relative the mechanism for indicating (24) are also provided. The system further includes a mechanism for sensing (30) the passing and identity of the mechanism for indicating (24) and the passing of the mechanism for designating (28), wherein the propulsion system (12), the mechanism for indicating (24), the mechanism for designating (28), and the mechanism for sensing (30) have geometric relationship defined by geometric parameters. A device for determining time between the passing of the mechanism for indicating (24) and the mechanism for designating (28) and for determining the blade angle from the time, identity, and a plurality of the geometric parameters is also included. A method for determining blade angle is also disclosed.
