基于主客观权重方法的某战机起飞阶段飞行品质评价

Evaluation of flying qualities of a fighter during takeoff stage based onsubjective and objective weight method

摘要:

飞行品质评价是飞行训练评估的重要组成部分具有重要的应用价值。针对传统飞行品质评价方法中主客观评价的局限性，提出一种主客观综合集成的评价方法。通过非线性映射的方法将飞行参数数据转化为可评价的数据，采用层次分析法（AHP）确定主观权重值，利用信息熵理论计算客观权重值，将客观权重值与主观权重值进行优化计算得出综合评价权重值，最后进行主客观综合评价。通过某型飞机起飞离地时刻数据为实例进行验证，并与现有评价方法对比，结果表明主客观权重集成法具有更高的准确性，为飞行品质评价提供了参考，对工程实践有很好的应用价值。

Abstract:

Flying quality evaluation is an important part of flight training evaluation and has important application value. In view of the limitations of subjective and objective evaluation in traditional flight quality evaluation methods, a subjective and objective meta synthesis evaluation method is proposed. The flight parameter data are converted into evaluable data by the nonlinear mapping method. The subjective weight value is determined by the analytic hierarchy process (AHP), the objective weight value is calculated by the information entropy theory, and the objective weight value and the subjective weight value are optimized to get the weight value of the comprehensive evaluation. Finally, the subjective and objective comprehensive evaluation is carried out. The results show that the integrated method of subjective and objective weight is more accurate, and provides a reference for the evaluation of flight quality, and has a good application value for engineering practice.
