一类公务机客舱布置的多目标优化

Multi-objective Optimization for Passenger Cabin Arrangement of Certain Kind of Business Aircraft

针对双发涡扇公务机在总体设计阶段的客舱布置,建立了基于经济性与舒适性的优化模型并计算了一个案例。运用回归分析对大量该类飞机的历史数据进行了统计分析,得到了若干客舱几何参数与飞机总体参数及经济性、舒适性指标的数学关系式,并提出了两类指标的数学模型并进行了无量纲化。最后通过线性加权法求解了基于经济性与舒适性的多目标优化问题的一个案例。为在飞机总体设计阶段优化客舱布置提供了一个可行的方案。

Aimed at the passenger cabin arrangement in the overall design period of twin engine turbofan business aircraft, this paper built an optimization model based on economy and comfort and calculated a case. It analyzed massive historical data of this kind of business aircraft, obtained certain mathematical relations of passenger cabin geometric parameters, aircraft configuration parameters, economic index and comfort index, and on this basis proposed the model of economic index and comfort index, and furthermore made it dimensionless. In final, it solved a case of multi-objective optimization, which is based on economy and comfort, by the linear weighted method. This paper provided a feasible solution for optimizing the passenger cabin arrangement in the overall design period.
