Analysis of impact of use of composite materials on direct operating costs of airliners

  • 摘要: 在飞机总体方案设计阶段需要评估复合材料应用对客机直接运营成本(DOC)的影响.以客机总体方案综合分析和优化系统为基础,对复合材料应用带来的质量减轻和成本增加进行了分析,给出了质量和成本的修正估算模型,提出了一种复合材料在客机应用中的效益定量评估方法.以150座级客机为例,首先分析了客机复合材料全机用量质量百分比对DOC的影响,然后以此优化结果为基准,分析了油价上涨、飞机价格和维修成本的变化对DOC的影响.结果表明:随复合材料全机用量百分比增加,客机的DOC呈下降趋势;随航空燃油价格的上涨,复合材料在客机中的应用能带来较为显著的经济效益;复合材料机体制造成本和维修成本的降低,可使复合材料客机DOC的下降更显著.
