摘要
宽体客机研发模式已从传统"单一机型"向"系列化机型"转变。根据宽体客机系列化设计通用性准则,对其设计方法进行了研究。建立了以宽体客机系列化设计制造成本、最大起飞重量间差值总和为目标函数,各机型商载能力为约束条件的宽体客机系列化设计模型。利用非劣排序遗传算法(NSGAII),对宽体客机系列化设计模型求解,得到符合条件的Pareto解集,取解集中的两个方案进行比较分析,其结果具有一定的实际意义,为宽体客机制造商在宽体客机系列化设计过程中商载航程的选取提供了一种依据。
There has been a transformation from single mode to family with the conception of the wide- body aircraft family. According to the general criterion, the design method has been studied and then establish the model which takes the economic index and the maximum take off weight（MTOW） as the object function, payload as the restrains. With the application of the Fast non- dominated sorting genetic algorithm（ NSGAII）, the solution has got. Two answers comparison of different design schemes was carried and the meaningful analyzing results provide a basis for the conceptual design of the aircraft family.
