现在,新一代的窄体飞机正在悄然升级,在航线试飞和实际运营阶段,均显现出了不同凡响。在过去的几年里,飞机制造商都对新一代窄体飞机的发展很重视,尤其是把关键点放在了提升发动机效率上,以增加续航和载运能力。目前,这类机型使用较为普遍的是CFM国际公司的Leap发动机,以及普拉特·惠特尼公司的GTF发动机。它们的优势在于燃油使用效率提高了15-16%。空客和波音两家公司的新机型一般均使用Leap发动机,但
Now, a new generation of narrow-body aircraft is quietly upgraded, in the flight test flight and the actual operational phase, have shown a remarkable. In the past few years, aircraft manufacturers have attached great importance to the development of next-generation narrow-body aircraft. In particular, the key point is to improve engine efficiency to increase battery life and capacity. Currently, the more common use of such models is the Leap engine from CFM International and the GTF engine from Pratt & Whitney. Their advantage is the increased fuel efficiency of 15-16%. Leap engines are generally used for the new aircraft from both Airbus and Boeing
