Apparatus for measuring the freeplay of control surface of an airplane

摘要

the present invention is to play in the development of aircraft jojongmyeon (Freeplay) to more easily and accurately measured by the aircraft 's jojongmyeon is to accurately calculate the parts replacement cycle of the clearance measuring device and a measuring method of the aircraft jojongmyeon to improve the handling and stability of the aircraft . ; aircraft clearance measuring device of the adjustment surface according to the present invention , jojongmyeon loading portion and for rotating the vertical direction by the jojongmyeon applying a predetermined external force to ; Is disposed in contact with one side of the two displacement measurement jojongmyeon sensor for converting the displacement measured by the electrical signal to measure the displacement of the jojongmyeon ; Is connected to a displacement sensor and an output device for outputting an electric signal the displacement measured from the displacement measuring sensors .
