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.Abstract: The impact of the use of composite materials on the direct operating cost (DOC) of airliners needs to be evaluated at the preliminary stage of aircraft design. An analysis of the influence of the use of composite materials on aircraft cost and weight was carried out. A revised model for airliner weight and cost estimation was developed. An evaluation method was proposed to quantify the benefits of the use of composite materials in airliner design. A 150-seat airliner was used as a case for study. The impact of the percentage of the use of composite materials on DOC was evaluated for airliner design. The impacts of the fluctuation of aircraft price, fuel price and maintenance cost on DOC were investigated. The results show that the DOC of airliners declines with the increase of the percentage of the use of composite materials. With the increase of fuel prices, application of composite materials in aircraft design can bring remarkable economic benefits as the reduction of the costs of manufacturing and maintenance of the airframe of composite materials can lead to a significant decrease of the DOC of aircrafts of composite materials.
