Research And Apply Of Aero-engine Fault Diagnose Based On Artificial Neutral Network

Aero-Engine is the heart of the airplane, is a system having the most ratio of trouble in the specialty of mechanism, and having the most work to do. The condition of the engine has the direct influence of the safety of the airplane. In the current, the Aero-Engine'faulting rate rising clearly with the improving task of the Aero-army. So, the research of the diagnosing of the trouble based on the plane's engine has important significance to improve the Aero-army's capability of the guarantee.In this article, it has placed the emphasis on the characteristic of the neutral net, and pointed the practicality and the necessity of the combination of the neutral network and the fault diagnosis. The article has researched the choices of the net's layers, the primary'authority in the practical part.The article has produced a new improved method based on the primary Back-Prop algorithm'defects, and by the use of the two methods to the WS-11 Aero-engines with the fault diagnoses software, proved the practicality and the superiority to the old on the rate of study and the exact of fault. At the same time, the outcome of the running has proved the exactitude and the practicality of the research's work.
