基于市场航线数据的民用宽体飞机寿命研究

The Life of Wide-body Commercial Aircraft Research Based on Airlines Data

为了合理确定我国宽体客机的服役寿命,对不同市场区域内的航线开展了分析和研究。通过对双通道宽体客机运行航线的统计和梳理,列出了不同约束条件下宽体客机运行航线的不同特点和规律,以及对宽体飞机设计服役寿命的影响,其中重点指出了不能忽视"潜在客户"这一重要影响因素。"有所为,有所不为"是我国双通道宽体客机市场定位的原则,避免"大而全"。在宽体客机服役寿命确定的过程中,前提是要立足中国,并辐射亚太地区的基本市场,果断剔除目标市场内那些不具可行性但又对设计服役寿命影响巨大的运营航线,为我国双通道宽体客机的发展"减负",充分发挥后发优势,增强宽体飞机的航线适应性和竞争力。

For defining the design service life of China double aisles wide-body commercial aircraft, the global double aisles wide-body commercial aircraft airlines are researched and analyzed. Through collecting and classifying the double aisles wide-body commercial aircraft airlines data, the primary effect factors are provided and classified. With considering different effect factors, especially the factor of ＂potential customers＂, the wide-body commercial aircraft airlines characteristics are different, and the design service life is also different. The market should be cut off exactly, but not be accepted it all. The basal market of China double aisles wide-body commercial aircraft is in the zone of China, Asia and the Pacific. In this zone, potential customers should be analyzed carefully, the cus- tomers who are not available and also play an important role in this zone should be picked off decisively. The exact market for China double aisles wide-body commercial aircraft could reduce engineering difficulties, and also in- crease airlines adaptability and competition in the specific market zone.
