Abstract : The patent describes a sensor mechanism provided to detect movements of rudders about axes which are perpendicular to a propreller axis on a propeller-driven vehicle. Follower arms are configured to engage rudders of the propeller-driven vehicle and be moved in response to movements thereof. The followers are constrained to rotate about a fixed shaft, the rotation of which is coupled, via suitable mechanical amplifier means, to electromechanical transducer. An interlock is provided to cause the arms to engage the rudders when the mechanism is mounted on the propeller shaft and to retract the followers to inoperative position when the device is removed from the propeller shaft.
