摘要
针对航空反潜机机动性能评估的问题,确立了反潜机机动性能的评估指标集,建立了待评估样品的数据矩阵,用多元统计中的主成分分析法对样本矩阵进行统计分析,以样品第一主成分得分值构造系统排序评估指数,以评估指数对各个样品进行排序。用此方法对各种不同反潜机的综合机动性能进行评估并排序,所得结果与实际情况相符合,能客观有效反映飞机的综合机动性能。
Aiming at the problem of evaluating the maneuverability of aircraft which is useful for detection and aviation against submarine, this paper establishes the evaluation indexes collection of the aircraft and the index matrix of samples to be sorted, and uses the first principal component value of samples for constructing an evaluation index of multi - index system and sorts the samples with this method. In an illustrative example, the synthetic maneuverability of different kinds of aircraft is sorted by using the method proposed in this paper. The result obtained is consistent with the real situation. The example shows that the method is effective and objective thus can be used to evaluate the synthetic maneuverability of aircraft objectively.
