航空运营商追求飞机运营效率最大化,欧洲推出新的环保排放标准,以及大批窄体飞机正在逐渐走向老龄化等因素,已经成为推动新一代窄体飞机发展的驱动器。面对航空公司用户的迫切需求,如今在窄体飞机市场上已获利颇丰的波音和空客将做何打算?支持下一代窄体飞机性能实现突破性进步的关键技术是否能适时到位? The pursuit of maximizing the efficiency of aircraft operations, the introduction of new environmental emission standards in Europe, and the gradual aging of a large number of narrow-body aircraft have become the drivers for the development of a new generation of narrow-body aircraft. In the face of the urgent needs of airline users, what are the benefits of Boeing and Airbus, which have made great profits in narrow-body aircraft market today, and whether the key technologies that will enable breakthroughs in the performance of next-generation narrow-body aircraft will be put in place in time?
