人们通常把发动机称为飞机的心脏,这种比喻是相当确切的。飞机和发动机相依相成,发动机产生推力使飞机向前高速推进,在机翼上造成升力,飞机就得以升上高空,没有发动机飞机就不能运动更不能上天。而在另一方面,发动机是因飞机而产生的,要不是装在飞机上,发动机也无法发挥作用,只有装备某种发动机的飞机得以成批生产并在市场上销售,该发动机才有机会得到不断发展改进。一些专家曾说,有什么样的发动机就有什么样的飞机,这是说飞机的各种性能,包括速度,高度以及机动性,经济性,环保性等,在很大程度上是取决于发动机。因此如果说想要成功地 The analogy is fairly definite as people usually call the engine the heart of an airplane. The aircraft and the engine depend on each other. The engine produces thrust to push the aircraft forward at high speed, causing lift on the wing, and the aircraft can rise to high altitude. Without the engine, the aircraft can not move and can not go to heaven. On the other hand, the engine is generated by the aircraft, the engine can not function unless it is installed on the aircraft, and the engine can only be obtained if the aircraft equipped with the engine can be mass-produced and marketed Continuous development and improvement. Some experts have said that there are what kind of engine what kind of aircraft, which is said that the aircraft’s various performance, including speed, height and mobility, economy, environmental protection, etc., largely depends on the engine . So if you want to succeed
