Helicopter noncontact-type manipulation quantity calibration method

The invention relates to a helicopter noncontact-type manipulation quantity calibration method, which is characterized in that input quantity of a manipulation system is determined by a control column, a total distance bar and a foot board, the direct measurement of the deviation quantity of the manipulation system is changed to a way by utilizing a laser linear displacement sensor LS to directly measure a linear distance L from an installation position of the manipulation system to a rocker arm in an manipulation linear system, and the calibration method is a noncontact-type manipulation quantity calibration method. An inclination angle of a main rotor blade on each of the four azimuth angles of 0, 90 DEG, 180 DEG and 270 DEG is respectively measured by an obliquity sensor, a total elongation of a main rotor, a longitudinal-transverse periodical variable-pitch angle and a total elongation of a tail rotor are respectively calculated by utilizing a formula, so that a calibration relation of the noncontact-type manipulation quantity L and the variable elongation can be realized. The calibration method comprises the following steps of calibration of total distance, calibration of longitudinal-transverse laser linear displacement sensor LS and calibration of a navigation laser linear displacement sensor LS. The calibration method has a good application prospect in the technical fields such as aerospace, helicopters, unmanned planes and the like.
