飞机在100年前是如何出现的?又为何在浩瀚的空中,越飞越快,越飞越高?这都与强大的发动机动力有关。然而,相对于飞机来说,人们对百年来航空动力发展情况的了解却十分有限。为此,本刊将陆续刊登这方面的介绍文章,主要包括活塞螺桨发动机、涡轮喷气发动机、涡轮风扇发动机和桨轴发动机等。 How did the plane appear 100 years ago? And why the vastness of the sky, flying faster, flying higher? This is related to powerful engine power. However, compared with the aircraft, people’s understanding of the development of aviation power over the past century has been very limited. To this end, the publication will be published in this area one after another article, including piston propeller engine, turbojet engine, turbofan engine and propeller shaft engine.
