Aiming at the demend for real time monitoring of aircraft slat rail,a new method which based on electrostatic induction of condition monitoring method of early warning of fault is proposed.The foundational principle of electrostatic monitoring method is analyzed,the preliminary experiment research on electrostatic monitoring method is carried out.The result of the experiment shows that the electrostatic sensor can effectively detect changes in the electrostatic charge level due to fault,indicating availability of the application of electrostatic in the model of slat rail.The theory of short-time Fourier transform(STFT)is introduced.STFT is used to process the data,and its characteristics is analyzed.It provides a further research of airborne slat rail monitoring equipment.
