Measurement of movable wing surface deflection based on wireless inclination sensor
The dual measurement axis spatial rotation model was deduced and improved,by referring to the existing spatial angle measurement models and considering the system error of the aircraft testing site,based on the analysis of the underlying measurement principle of the inclination sensor.The purpose was to resolve the problems during the movable wing surface deflection test,such as high installation parallelism requirement,long cables and complex manual operations,so as to improve the measurement accuracy and the test efficiency.A spatial angle measurement error model around the horizontal axis and a calibration method for inclination sensor were proposed,to meet the requirement for the deflection testing.A large aircraft movable wing surface deflection testing system based on wireless inclination sensors was designed and implemented,capitalizing on this model and the calibration method.Results of the rotation angle accuracy testing on the experimental platform and the on-site testing on the movable wing surface show that,compared with the existing methods,the proposed calibration method can obtain a larger effective measurement range to meet the actual working conditions,improve the angle calibration accuracy,and significantly improve the testing efficiency.
