基于飞参数据的航空发动机故障预报研究

Research on Fault Forecast of Aeroengines Based on Flight Data

为了充分挖掘飞参数据的应用价值,研究了利用飞参历史数据对发动机进行故障预报的方法。从理论上分析了飞参数据中的几组参数与发动机性能的内在关系,论述了利用飞参历史数据对发动机的4类故障进行预报的可行性以及具体的预报方法,并结合某型飞机飞参系统实际记录的数据研究了该方法的应用。研究结果对于保障飞行安全具有重要意义。

In order to exploit the application value of flight data adequately,a method of fault forecast for aeroengines was studied with historical flight data.The internal connection between groups of parameters in flight data and aeroengine performance was analyzed.The feasibility and detailed methods of forecast for four kinds of aeroengines faults with historical flight data were recounted.Furthermore,the method was studied with practical flight data recorded by the flight data recorder of a plane.The results of the research can be very important for flight security.
