Build a "Iron and Steel Great Wall" to support the national backbone

In the roar of shocking the world, the flames on the test bench rolled, and the solid engine fire dragon danced, and the power of instantly burst out was shocking. Each test is engraved in the chapter of my country's aerospace solid power.

In 1962, with the proposal of Qian Xuesen, the Fifth Research Institute of the Ministry of National Defense was established in Luzhou, Sichuan, and China's aerospace solid power business started: The actual solid solid engine, from sending "Dongfanghong No. 1" to the successful launch of the first commercial aerospace, from a single -purpose solid engine to a variety of strategies, tactics, and sacred power products and systems in the entire application field ... Mowing

In 60 years, China ’s aerospace solid power has continued to develop in heritage and gradually grow in innovation.

Career, starting with a humble small barrier

At the foot of Daqing Mountain in Inner Mongolia, my country's first large -scale solid rocket engine trial station stood tough -because of being burned by fire, the steel bars on the trial platform were exposed, the inner and outer walls were motionless, and the thrust wall also deformed due to the impact of flames.

Behind this is a story about mission.

The freshman China not only faces the rotten stalls of domestic sores and poverty, but also internationally facing the continuous explicit nuclear deterrent of superpowers with nuclear monopoly technology, and the crisis is heavy.

Compared with liquid power, aerospace solid missiles have the advantages of structural compactness, high reliability, good mobility, and short launch preparation time, leading the trend of advanced weapons in the world. In order to make the Chinese waist pole really stand up, the Chinese must develop their own solid missiles!

At that time, China, the material foundation of solid propellant research work was blank. The main pioneer of solid rocket technology Li Nai and the young astronauts of the solid rocket technology ran around, querying the information, and a micro exploring. Finally, the composite pushing agent finally started in early 1958. Tackling.

In July 1958, at the conference of the results of the Fifth Hospital of the Ministry of National Defense, a pencil -sized gray solid barbaria was clamped by a pointed tongs to ignite, and the venue applauded. This gray medicine that looks inconspicuously rubbed and humble is the first solid medicine bar developed by Chinese aerospace people. Hope.

In 1962, the Fifth Research Institute of the Ministry of National Defense set up a solid engine research institute in the high dam in the suburbs of the small town in southern Sichuan. "Chinese people want to engage in aerospace solid power, and they can only rely on self -reliance. Expect someone to help you, impossible!" Zhao Dianli, an old expert in the Sixth Academy of Chinese Aerospace Science and Technology, recalled, "The early work was very difficult, and only some tests were performed in Sichuan in 3 years in Sichuan. Instrument, but I exercise a hero's team. "

As soon as there is nothing, carrying the motherland's heavy trust and the hope of the nation

In the autumn of 1965, thousands of people in Inner Mongolia's R & D and production bases under construction were poured into thousands of people. Among them are graduates from Tsinghua, Peking University and other universities, experts and international students returning from abroad, and management and technical talents supported from all over the country. They are aimed at the high point of the world's solid rocket technology development system -the core technology of solid power!

Several empty factories, several dormitories, and a cafeteria made of thatch. They are long and yellow, and they start from scratch. The office is both the classroom and the dormitory. There are only two hand -shaking computers and a few map boards. The food supply is mainly corn and sorghum. I was frozen. "I didn't dare to think about such a hard scene before, let alone see it." This year, Yang Peijuan, 79, was an expert who participated in the aid at the time. Recalling the scene from Shanghai to Inner Mongolia that year, she was still vivid. Essence

Behind this is the sense of mission of their responsibility. In September 1965, the central government determined that the development of artificial satellites was listed as a major task for the development of national cutting -edge technology. In December 1966, entrepreneurs in Inner Mongolia received a mission letter and were ordered to complete the third -level engine of the Long March 1 Rocket.

At this time, the factory of the Inner Mongolia base was still under construction, and there was no complete development and production conditions. Researchers conducted scientific research and production, and built into walls with a solid sand. On the Gobi, they are everywhere in the hot scenes of the heat, the cold, and the fighting wind sand.

Hard work pays off! On April 24, 1970, the Long March 1 rocket rushed to Yun Tian with the "Oriental Red One" satellite. Relying on the final push of the third -level solid engine, the Chinese first artificial satellite "Orient Red One" speed up By the speed of the first universe, successful.

China has entered the space age.

The Zhuang Kingdom is Wei Zhenmin's heart, and stands up in the back of the country

In the late 1970s, my country transferred the scientific and production power of solid power fields to transfer most of the technical backbone personnel, important equipment and key tasks to Xi'an, and the remaining personnel stayed at Inner Mongolia base (renamed China Aerospace in 1999 to China Aerospace The Sixth Research Institute of Science and Technology Group).

The core personnel have gone, and the task has decreased significantly without any pre -research items. At an important moment, the Inner Mongolia base decided to take independent innovation as a breakthrough, starting from scratch again, using technological innovation as the focus of work, and entrepreneurship. The development of "five machines and ten questions" (that is, 5 new engines and 10 pre -research topics) was organized.

During that period of extremely difficult period, workers at Inner Mongolia base did not forget the red gene of the Chinese aerospace solid power. They chose to persist, self -improvement, independent innovation, and set their sights on the competitive international market for the first time. At that time, the Inner Mongolia base obtained an international order for the development of a near -place orbiting engine, but there was no such development experience before. If it fails, it will not be estimated to be unfavorable. However, if the development is successful, China can break the technical blockade of the European and American rail changing engines and have a place in the international launch field.

This is a major event for Zhuang Guowei and the heart!

At the beginning, the development work was smooth. However, when the first trial test was conducted, the engine had just worked to 43.9 seconds, and the head was on the fire. The people present were all silent ...

The second time, it failed again ...

Even international users almost lost confidence. But the cadres and employees of the Inner Mongolia base were relieved: what Americans can do, the Chinese can do it, and they will be more beautiful!

Gao Chongwu, the old leader of the Sixth Hospital of China Aerospace Science and Technology, recalled that the third test was called "the test of life". Everyone cares about this too much. On that day, all employees and family members brought their children, and they were all people in the mountains.

After the engine was ignited, the fire dragon danced, the lightning flashed thunder, 43 seconds, 51 seconds until 90 seconds, successful!

Many years later, people are still excited: this time the test not only allows the world to recognize the level and ability of Chinese aerospace solid power technology, but also see the spirit of Chinese aerospace! With such a spirit, why not worry about your career!

Energy from low to high, the application field from narrow to width

"Giant Wave No. 1", a near -place rail -changing rocket engine EPKM, a return brake rocket solid engine "Pioneer" ... the "first" of more than 10 Chinese aerospace solid power business, forming solid power covering the entire application field Product spectrum.

Speaking of now, Chen Keming, an old expert in the Sixth Academy of Chinese Aerospace Science and Technology, marveling at "the change is too much." And this change is more reflected in serving the economic and social development.

A thickness of the thickness of the hair is only one -third of the hair, but it keeps pulling. If it is made into a diameter of 12 mm thick, it can pull 46 tons of heavy objects, and the same thick steel rope can only pull 8 tons. "It has a strong anti -cuttability. If it is made into clothes, it is the legendary 'soft hedgehog nerry' in Wulin." Said 46 heads of China Aerospace Science and Technology Sixth Academy.

This filament is neither cotton nor silk nor silk, but the F-12 high-strength organic fiber developed by the Sixth Hospital of China Aerospace Science and Technology for more than ten years. Earlier, this type of fiber was used as aerospace development materials and important strategic materials secrets. The development of F-12 successfully filled the gap of domestic high-strength organic fiber materials.

At present, my country's "F-12 fiber-fiber fabric-flexible functional composite material-material products" industry chain is initially formed.

The list goes on. While consolidating the advantages of the traditional field of solid equipment, today's Sixth Chinese Aerospace Science and Technology Hospital has become an important leader and an important original technical strategy for my country's aerospace solid power. The multi -sized, wide range, series of solid power product systems, firmly constructing a comprehensive and multi -level "Iron and Steel Great Wall" of land, sea, air, and heaven in my country.

"The achievements of the Chinese solid rocket engine have rely on self -reliance, without foreign aid, and have not passed the imitation stage. This is a great result and the pride of the Chinese nation." Qian Xuesen once commented.

During the sixty years, several generations of astronauts advanced to the mountains, went to the wasteland, and moved to Gobi. The engine diameter was from small to large, energy from low to high, and the application field was narrow to width, entering high -quality fast lanes. According to Liu Wenjun, the president of the Sixth Academy of Aerospace Science and Technology, this is the continuous inheritance of the spirit of Chinese aerospace!
