Why is he called the “chief designer” of China’s aerospace industry?

Ren Xinmin, one of the important pioneers of China's missile and aerospace technology, winner of the "Two Bombs and One Satellite Medal of Merit", is known as the "chief architect" of China's aerospace industry. He has lived a magnificent life, but he said, "I have only done aerospace in my life" and "my personal future is not worth mentioning in front of the motherland!"

In 1915, Ren Xinmin was born in Ningguo, Anhui.

In 1929, he was full of enthusiasm for saving the country.

Joined the Communist Youth League of China

After the July 7 Incident

Ren Xinmin was admitted to the Chongqing Military and Political Department Ordnance School

Learn the design, manufacture and use of guns and cannons

Developing guns, artillery and gunpowder for the Anti-Japanese War

He took the first step in his ambition to save the country through science and technology.

In 1945, Ren Xinmin went to study at the University of Michigan in the United States

He received a master's degree in mechanical engineering and a doctorate in engineering mechanics.

In 1949, he overcame numerous obstacles and returned to his motherland

Participated in the establishment of Harbin Military Engineering College

Cultivate scientific and technological talents for the development and use of weapons and equipment

After 1956

Ren Xinmin participated in the establishment of the Fifth Research Institute of the Ministry of National Defense

1958

He was appointed as the chief designer of the "1059" engine

On November 5, 1960, "1059" was successfully launched

Marshal Nie Rongzhen said

"This is the first time in the history of our country's military equipment

An important turning point

"1059" was later renamed "Dongfeng-1"

Dongfeng family in the journey of China's missile industry

Continuous development

Becoming the "national treasure" of China's modern national defense

As the chief technical officer of the DF-4

Ren Xinmin led the research team to make a breakthrough

my country's first high-altitude engine under development

Multiple technical problems

Since 1968

He is stationed at launch sites in the Gobi Desert and the cold regions of Northeast China.

Leaders participated

"Dongfeng 3", "Dongfeng 4", "Long March 1"

Research and development test work

In 1970, the Dongfeng-4 was successfully launched.

For the Long March 1 launch vehicle

Laying a solid foundation

April 24, 1970

The "Long March 1" carried the "Dongfanghong 1" into space

The National Broadcasting Administration received

The song "The East is Red" broadcast by China's first satellite

my country's first artificial satellite was successfully launched

Although China successfully launched the "Dongfanghong-1" satellite

But its operating height

and the height that communication satellites need to reach

There is still a long way to go

In order to successfully send the satellite to the required altitude

Ren Xinmin focused his attention on

The third-stage power unit of the Long March 3 carrier rocket

All the controversy revolves around fuel

Should conventional propellants be used?

Liquid hydrogen and liquid oxygen are used as propellants

After repeated research and discussion

Ren Xinmin made several adjustments to the hydrogen-oxygen engine

In the subsequent simple test run

The engine starts cleanly and the flame is stable

No more shrinkage phenomenon

He finally let go of the worry that had been weighing on his mind.

April 8, 1984

The Long March 3 carries the Dongfanghong 2 experimental satellite

Launch

20 minutes later, the radio broadcast exciting news

"Rocket separation is normal

Satellite enters geosynchronous transfer orbit!"

China's first communications satellite

Ready to start communication test

April 18, 1984

Beijing and Xinjiang realize first satellite call

That is on this day

China Central Television

The first live TV broadcast

From participating in the development of the first ground-to-ground rocket

To launch the first artificial satellite

Then to experimental satellite communications, practical satellite communications,

"Fengyun-1" meteorological satellite, etc.

Ren Xinmin, chief designer of six major aerospace projects

Witnessed the glorious development of China's aerospace industry

Known as the "chief architect" of China's aerospace industry
