大家都知道螺旋桨飞机没有喷气式飞机飞得快,可这是为什么呢?要弄清这个问题,还要从两者的工作原理说起。我们知道,螺旋桨飞机是采用活塞式发动机,靠螺旋桨产生飞机前进的拉力。飞机上用的活塞式发动机跟现在汽车上用的发动机基本一样,只不过是轻巧一些、功率大一些。活塞 Everyone knows that a propeller jet does not fly faster than a jet jet, but why is this? To clarify this issue, let’s start with the working principle of both. We know that the propeller aircraft is the piston engine, by the propeller to produce the aircraft forward tension. The piston engine used in the aircraft is basically the same as the one used in the current car, except it is lighter and more powerful. piston
