Chinese aircraft factory and air

上星期参观了中国空军建军70周年的展览，看到运七、运八、轰六这些仿造基础上再发展的飞机，我忽然对1949年以前的中国航空工业产生了兴趣，从1903年莱特兄弟的第一架飞机上天开始，中国的航空工业是如何发展的呢？

I visited the aircraft exhibition of the Chinese air force last week. I was suddenly interested in China's aviation industry before 1949. How did China's aviation industry develop from 1903, when the Wright brothers successfully launched their first plane into the sky?

我查了一些资料，按照发展时间整理了一个简单的时间图谱，有这么几个结论：

I looked up some historical materials and created a time map.

1、1949年以前的中国飞机制造行业，也是以仿造为主；

Before 1945, China's aircraft manufacturing industry was based on repair and imitation.

2、中国航空工业的主要技术人员，除了少数日本、苏联留学的人，大多数都是美国留学回国人员；

Most of the technicians in China's aviation industry have returned Chian after studying in the United States

3、1945年以前的中国飞机制造行业，虽然自己也设计制造了一些飞机，但没有一架飞机使用的是自己生产的发动机，这个问题，在1949年后的几十年里，也一直严重制约着飞机性能的提升，直到近年，才有所改善。

None of the planes made in China before 1945 had engines designed and built in China. This problem, in the decades after 1949, has been a serious constraint on aircraft performance improvement.

4、自从抗战后期美国大量援助中国各型飞机开始，中国的航空工业就基本停止了发展。

Since the late Anti-Japanese War, when the United States provided a large amount of assistance to Chinese aircraft, China's aviation industry has basically stopped developing.

这个时间进程图中的人物、时间、型号等问题还需要认真考证，休息时间完成，以后一定认真考证。

The character, time, model and other issues in this time map to be carefully researched. I finish it in the break time, and I will definitely revise it later.

资料出处很多，待日后详细考证时再一一列出。

There are many sources of the historical materials, which will be listed one by one after revision.
