Research on reliability of aero-engine nacelle based on survival analysis

Research on reliability of aero-engine nacelle based on survival analysis This paper studies the reliability modeling of civil aircraft engine nacelles. Based on the fault record data of an aircraft over the years, the two-parameter Weibull model and the Cox proportional hazards model are used respectively. On MATLAB and SPSS software, reliability modeling was carried out for several important equipment of this type of aircraft.

Abstract

This paper studies the reliability modeling of civil aircraft engine nacelles. Based on the fault record data of an aircraft over the years, the two-parameter Weibull model and the Cox proportional hazards model are used respectively. On MATLAB and SPSS software, reliability modeling was carried out for several important equipment of this type of aircraft. And it was tested in the fault prediction to verify the feasibility of the model and prediction method.
