| 摘 要： | 针对民用飞机给出了其全寿命周期成本的计算模型,并提出了以该模型为目标的面向民用飞机总体参数的优化方法。同时,在Matlab开发平台上,开发出了该方法所需的遗传算法优化程序。为检验该方法的有效性,本文在历史数据的统计分析和处理的基础上,基于回归分析给出了相关公务机总体参数的估算公式,并以该类飞机为案例进行了计算。计算结果表明,优化方法可行,结果有一定的实际意义,可为飞机总体设计参数的选取提供一种依据。

| Abstract: | This paper obtained the life-circle cost calculating model for the civil aircraft,and based on this model,proposed the optimization method for the civil aircraft conceptual parameters.Furthermore,to implement the method,it developed the genetic algorithm optimization program on the MATLAB platform.To examine the effectiveness of this method,this paper presented the estimation formula of the relative business aircraft conceptual parameters by regression analysis on the basis of analyzing and processing of historical data,and implemented the calculation of this aircraft.The results show that the optimization method is feasible,and the results are of practical significance,which can provide reference for the selection of the aircraft conceptual design parameters. |
