与所有高端工业产品一样,一种新机型的诞生十分不易,而要想长久保持“青春”则更加艰难。在科技发展日新月异的今天,飞机制造商每年都要花几十亿美元用于现有机型的改进改型,以保证产品的竞争力。其中,为现有型号更换新一代发动机的策略往往是飞机制造商最常用的一种延续产品“职业生涯”的妙招。因为与研发一款新产品相比,换发的风险和资金投入要低得多。而对于用户来说,换发后的飞机不仅能够节省大量的燃油成本,而且与现有机队保持了高度一致。 Like all high-end industrial products, a new model is not that easy to create, and it’s harder to stay young for a long time. With the rapid development of science and technology, aircraft manufacturers spend billions of dollars each year on the improvement of existing models to ensure the competitiveness of their products. Among them, the strategy of replacing a new generation of engines with existing models is often the most common type of continuation product “career” that aircraft manufacturers use. Because compared with the development of a new product, replacement risk and capital investment is much lower. For users, the new aircraft not only saves a lot of fuel costs, but also maintains a high degree of consistency with the existing fleet.
