Abstract:
1. A device for measuring a vane surface contour of a propeller comprising: a shaft adapted to extend through a hub of a propeller having a plurality of vanes formed on the hub, with the shaft being rotatable to rotate the vanes about a vertical axis, and the vanes extending along radial directions of the shaft; a measuring unit adapted to be electrically connected to an electronic operational unit, with the measuring unit including a measuring rod having a measuring end and a movable portion, with the measuring rod being movable in a direction parallel to the vertical axis to abut the measuring end against a surface of one of the plurality of vanes of the propeller, with the measuring end moving in the direction parallel to the vertical axis in response to a surface contour of the surface of one of the plurality of vanes of the propeller when the shaft rotates, with the measuring rod being movable in a radial direction perpendicular to the vertical axis such that the measuring end of the measuring rod is movable between an innermost radial position and an outermost radial position of the surface of one of the plurality of vanes, with the measuring rod having an angle to the vertical axis, and with the measuring end being pivotable about the movable portion to adjust the angle between the measuring rod and the vertical axis.
