摘要:

为了通过客机的市场分析与总体设计的紧密结合进行关键设计指标的更充分的权衡,提出了从航线网络体系的视角进行指标集效能评价的方法。这一方法以燃油效率作为经济性评价准则,基于运营统计数据建立综合考虑航线航程概率及航线实际乘客数概率的运输周转量概率密度分布,结合客机运行空重的估算,计算出各条航线消耗的燃油重量,进而通过多轮次的仿真分析出不同指标集对应的燃油效率概率密度。分析结果有助于权衡各个指标集的潜在设计方案适合在何种航线上运营,以及从燃油效率的角度分析潜在设计方案对航空公司的吸引力。通过在一个算例中对航程和载客量的变化进行计算和分析,说明了所提方法的应用方式,最后对目前研究的局限之处和后续的研究方向进行了探讨。

Abstract:

In order to make more sufficient trade-off of key design indexes by combining the airliner market analysis with aircraft conceptual design,a design index sets evaluation method is proposed from the perspective of airline network system of systems.Fuel efficiency is considered as economic evaluation criteria in this method,and the probability density distribution of traffic volume which involves range probability and actual passenger number probability of the airlines is established based on the airline operational statistics.Combining with aircraft take-off weight estimation,the fuel weight of each airline is calculated,and then the probability density of fuel efficiency for different design index sets is obtained through multiple rounds of simulation.The analytical results are helpful to trade-off each design set for its most fitting operation airline,and they can also evaluate the attraction for airline companies from the perspective of fuel efficiency.The design index change of range and passenger number is analyzed through a case study and the application of proposed method is also demonstrated.Then the limitations of current research and future research direction are discussed.

Key words: airline network, system of systems, design index, trade-off, fuel efficiency, economic
