Reliability Analysis for Main Engine Control of CFM56-3 Engine

摘要

The MEC is the core component of the engine control system, and influences the system performance and flight safety. A Likelihood Value (LKV) test is used to determine the rank of distributions for raw data set of MEC, and the Maximum Likelihood Estimation (MLE) is used for estimating the parameters of the chosen distribution. The reliability analysis of MEC part life that not only helps to improve the aircraft safety level, but also to provide a theoretical basis for planning reasonable maintenance schedules and reducing maintenance costs.
