Method, device and equipment for predicting residual life of aviation precooler and storage medium

The invention discloses a method, device and equipment for predicting the residual life of an aviation precooler and a storage medium. The method comprises the following steps: acquiring current key parameter data of the precooler; according to the key parameter data and pre-obtained precooler life cycle stage corresponding conditions, whether the precooler currently belongs to a life cycle normal stage or not is determined; if not, fitting the key parameter data to obtain a fitted curve equation; and processing the fitted curve equation and the MLBF equation by using a multi-dimensional data updating correction model to obtain a residual life prediction value of the precooler. According to the method for predicting the residual life of the aviation precooler, the fitting curve equation and the MLBF equation are processed through the multi-dimensional data updating correction model, the residual life prediction value of the precooler is obtained, the prediction accuracy of the residual life of the precooler i
