摘要
航程和座级直接反映民用客机的市场定位,是飞机产品能否被市场广泛接受的关键因素。目前全球大型客机市场由波音和空客两家公司垄断,又细分为窄体客机、宽体客机和超大型客机等市场。其中,宽体客机的航程跨度较大,是否发展中、短程宽体客机的争论从未终止。伴随空客公司推出A330区域型客机,中短程宽体客机是否有利可图的争论更加炙手可热。有鉴于此,基于全参数化飞机模型,研究了特定座级下设计航程与机翼、发动机、特征重量、气动特性以及燃油经济性之间的关系,分析了设计航程对民用飞机总体设计带来的影响,从技术层面阐述了设计航程变化带来的收益及代价。
Seats number and design range, as direct reflection of marketing orientation, are the key parameters of a civil aircraft. The current global large airliner market is dominated by Boeing and Airbus, including narrow body aircraft, wide body aircraft and super large aircraft, among which the wide body aircrafts have a large scope of design range, Both Airbus and Boeing have settled the new generation of wide body aircraft as the remote type. However, the controversy of the de- velopment of medium and short range wide body aircraft has never stopped. As Airbus has launched the A330Reginal pro- ject, the profit of medium and short range wide body aircraft becomes hot debate. In view of this, large airliner with certain seats level is selected in this paper to analyze the combined impact of design range on wing, engine, aerodynamic perform- ance, characteristic weights, fuel efficiency and the operating cost, the influence of design range on civil aircraft overall de- sign is also illuminated. Finally the benefit and losses due to design range variation are concluded in the technical prospec-tive.
