| 根据航空发动机综合性能分析的需要，建立了某型航空发动机的综合性能评估模型。首先依据发动机工作状态的不同分别选取了合适的飞参数据作为性能评估指标，然后分别采用层次分析法和模糊隶属函数法计算了各性能评估指标的权重值和归一化值，并在此基础上采用线性加权和法计算了发动机综合性能评估值。实例分析表明，该模型得出的发动机综合性能评估值能够较好地反映发动机综合性能的好坏，对发动机的状态监控及故障诊断有着重要指导意义。 |

| In order to analyze the aeroengine comprehensive performance, the evaluation model was set up. Firstly, with different aeroengine working states the suitable flight data were selected as performance evaluation indexes. Then the analytic hierarchy process and fuzzy membership function were used to calculate the weight values and the normalization values of the performance evaluation indexes respectively, and the aeroengine comprehensive performance value was calculated by using the linear weighted sum method. The example analysis showed that, the aeroengine comprehensive performance value which was calculated by the evaluation model could well reflect the good and bad of aeroengine comprehensive performance and had an important guiding significance to the condition monitoring and fault diagnosis of aeroengine. |
