Civil Aviation Engine Performance Monitoring And Forecasting Methods Research

The monitor and forecast for engine performance can not only safeguard the flight safety of aircraft, but also in the precondition of safeguard the flight safety , providing the foundation for finding the optimum maintenance time , reducing the cost of engine maintenance, and saving the aviation companies operated cost. In the paper, author mainly take part in the study work , which forecast the time of engine disassembly maintenance according to the engine performance, and present the prophase work for following finding the optimum maintenance cost time in safety precondition.In the paper , the study work include 3 section, as following : first, illustrating the history of engine performance monitor , civil aviation maintenance on condition , the meaning and monitor technology of civil aviation engine monitor ; second, stating the study for engine performance queue and engine disassembly removing forecast; last , according to the requirement of China Eastern Airlines to engine monitoring , design the aircraft engine performance monitoring and forecast software system.
