民用飞机产品开发的模式已从“单型飞机”的概念向“飞机系列”概念转化.根据模块化和通用性的策略,发展了飞机系列化设计方法,给出了飞机系列主要参数的设计原则和飞机系列经济性的描述方法,建立了飞机系列商载航程匹配设计模型.分析了商载和航程的匹配关系对飞机系列经济性的影响,利用Pareto多目标遗传算法,完成了某一民用飞机系列商载和航程的匹配设计,对不同设计方案的参数进行了比较分析,取得了较好的设计结果.
The model of civil aircraft product development has been transformed from the concept of “single-type aircraft” to the concept of “aircraft series.” Based on the modular and versatile strategy, a series of aircraft design methods have been developed, and the main series of aircraft series The design principle of the parameters and the method of describing the economy of the aircraft series, the model of the aircraft series commercial voyage matching design was established.The impact of the matching between the commercial vehicle and the voyage on the aircraft economy was analyzed. Using the Pareto multi-objective genetic algorithm, A civil aircraft series of commercial and voyage matching design, the parameters of different design programs were compared and achieved good design results.
