    摘要: An assembly for determining the longitudinal displacement of a rotating shaft, which incorporates a shaft displacement detector comprises:
    - a detector means;
    and - at least one detectable section provided in relation to the shaft, and which can be detected by the detector means;
    wherein the detected property or properties of the detectable section vary dependent upon the longitudinal displacement of the shaft. The invention also includes a propeller blade assembly including an assembly in accordance with the present invention, and methods of operating the assembly and propeller blade assembly.

    摘要: A blade pitch adjustment system comprising a yoke 2 arranged to be moved in a first direction in response to an actuator 5; a plurality of trunnion pins 3 arranged to be attached to a respective propeller blade; a respective contact surface 4 between the yoke and each trunnion pin such that movement of the yoke causes rotation of the blades, and wherein the contact surfaces differ so as to create different angles of rotation of the blades at different points of yoke movement or actuator stroke.

    摘要: The invention concerns a device (1) for controlling the pitch of the blades of a fan (4) rotor (3), comprising a radial shaft (6) linked to the blade, a connection rod (8) of which the axial movement controls the rotation of the radial shaft (6), characterised in that it comprises: -a first part (10) that is mobile in rotation with the rotor (3) about the axis (11) of the fan (4), and on which one end of each connection rod (8) is secured, -a second part (12) linked to the first part (10), and -at least three cylinders (14) capable of moving said second part (12) in axial translation, and of varying the tilt of said second part, the translation and tilt of the second part (12) driving a corresponding translation and tilt of the first part (10), such that, when the first part (10) rotates, each connection rod (8) is subject to axial displacement of which the amplitude is variable and is a function of the tilt of the first part (10), making it possible to vary the pitch of the blade during the rotation of same. The invention also concerns a fan, and a method for controlling the pitch of blades.

    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.
