喷气客机重量、性能和经济性综合评估方法研究

A Quick Evaluation Approach of Weights,Performance and Economics of A Jet Passenger Aircraft

利用现役喷气客机的技术和价格数据,建立了飞机客座数和设计航程要求与飞机最大起飞重量、使用空重、任务用油、飞机售价和直接运行成本之间的函数关系。通过对典型窄体机A320的分析,表明该计算模型具有较高的计算精度,适用于喷气客机初步设计阶段的技术经济方案的快速评估和竞争分析。

In aircraft preliminary design,when aircraft seat capacity and design range are selected based on marketing studies,the designer needs to define the aircraft in terms of maximum take off weight,operating empty weight,fuel capacity and operating economics.Based on weight and price data of current jet passenger aircraft,the paper gives a method to estimate max.Take off weight,operating empty weight,mission fuel,aircraft price and direct operating costs only from aircraft seat capacity and design range requirements.An example analysis of A320 shows that the method is suitable for quick evaluation in aircraft preliminary design.
