飞机时速多少是航空领域中的一个重要指标，它决定了飞行的效率和速度。随着科技的不断进步，飞机的时速也在不断提高。本文将探讨飞机时速的发展历程以及对航空业的影响。

首先，让我们回顾一下飞机时速发展的历史。20世纪初，飞机的时速仅能达到每小时60公里左右。当时的飞机采用螺旋桨推进器作为动力装置，速度受限于引擎的性能和飞机结构的限制。然而，随着喷气发动机的发明和使用，飞机的时速得到了革命性的提升。喷气发动机不仅功率强大，而且燃料效率高，使得飞机可以以更高的速度飞行。

In the early 20th century, the speed of airplanes was only around 60 kilometers per hour. The airplanes at that time were powered by propellers and their speed was limited by engine performance and aircraft structure. However, with the invention and use of jet engines, the speed of airplanes underwent a revolutionary improvement. Jet engines not only provided more power but also had higher fuel efficiency, enabling airplanes to fly at much higher speeds.
