Abstract:

The aircraft hydraulic system is the power device in the whole machine system. The selection of which hydraulic system in the process of aircraft designing is an important issue that needs careful consideration. However, there is no systematic theory for the evaluation of hydraulic systems at home and abroad. The reason is that there are many factors that affect the energy efficiency of hydraulic systems, including reliability, weight, and cost. For multi-objective comprehensive evaluation, it is an important link to consider the influence factors of various factors on the evaluation objectives. This paper uses the means of analytic hierarchy process (AHP) and fuzzy analytic hierarchy process (FAHP) to construct the evaluation model of current airplane's hydraulic system. By comparing the results of these two models, a conclusion could be obtained that Fuzzy AHP not only has greatly distinct with the similar object, but also avoids the drawbacks that the consistency of thinking in the analytic hierarchy process is difficult to be guaranteed.
