Research on the helicopter TBF prediction

Time between failures (TBF) is one of the most important indexes of the helicopter availability and reliability. Face to the helicopter characteristics, the prediction model could be constructed based on the grey theory, and the predictive data would be compared with the actual data. The results shows that the model could have a good precision and also could provide a reference to the prediction on the research of TBF, which would have value and meaning on practice and engineering.
