航空科学航空科学的建立和其他的科学一样,是由於许多劳动人民在不懈的努力中,鑽研某种自然现象而掌握了其规律的结果。航空科学的发展,主要的是由於鑽研了空气的运动;掌握了空气运动的规律。自从人想学飞鸟的在天空翱翔以来,空气流动的性能便逐渐地引起了人们的注意,经过许多人的体力和脑力劳动,关於空气流动性能研究的发展是相当惊人的。目前,一架全金属的重型飞机,装载着数吨的重量,可以在人力的控制下,自由地在空中翱翔了。在飞行速度方面进展也是十分惊人的,已远超过鸟的飞行速度而和声音在空气中的传播速度相抗衡了。
The establishment of aeronautics and aviation science is just like other sciences. It is due to the fact that many working people have studied their own laws in a constant effort to grasp certain natural phenomena. The development of aeronautical science is mainly due to the study of the movement of air and the mastery of the laws of air movement. Since people want to learn to fly birds and soar in the sky, the performance of air flow has gradually attracted people’s attention. After many people’s physical and mental work, the development of research on air flow performance is quite amazing. At present, an all-metal heavy-duty aircraft, carrying several tons of weight, can freely fly in the air under the control of manpower. The progress in flight speed is also extremely alarming. It has far surpassed the flying speed of birds and competed with the speed of sound propagation in the air.
