摘要
针对航空发动机性能不易准确评估问题,采用了一种基于改进逼近于理想解的排序法和组合赋权的多性能参数的航空发动机综合评估方法。首先,利用熵权法和层次分析法分别计算航空发动机各评价指标的权重,再通过组合赋权法得到主客观意义的综合权重,最后由各评价指标的综合权重和改进TOPSIS法计算出航空发动机性能综合评估结果。最终将模型应用于实例分析,对多台发动机性能状态进行评估以及对单台发动机进行性能趋势分析,结果验证了该方法的有效性,具有很好的工程应用价值。
It is difficult to accurately assess the performance of aero-engine. A method of comprehensive assessment of aero-e ngine performancewas used based on improving TOPSIS and combinational weight. Firstly, the weights of each evaluation index were calculated using entropy weight method and analytic hierarchy, then the comprehensive weight of each evaluating indicator was determined by weighting approach. Finally, the results about comprehensive performance assessment of aero-engines were calculated by the comprehensive weight of each evaluating indicator and improved TOPSIS method. The performances of many aero-engines were assessed and the performance trend of single aero-engine was analyzed. The results verified this method is effective, which is good for engineering application.
