"Gold Medal Rocket" Long Erbou 40th Anniversary | "Veterans" born

On September 9, 2022, the Long March No. 2 Cross Rockets (referred to as the "Long Erbing Rocket") ushered in the 40th anniversary of the first flight. In the past 40 years, the Long Erbing Rockets flew a perfect trajectory, and successfully completed a variety of satellite launch tasks of different tracks at home and abroad with extraordinary strength, leaving a series of glorious footprints on the road to exploring the "Long March" of the universe.

Develop in the forge and move forward in innovation. From the successful flight on September 9, 1982, to today's steady and continuous success. Long Erbing Rockets are one of the most reliable rockets in my country. In the name of China's first "gold medal rocket", it helps the Long March series of rockets , Lay a solid foundation for the construction of the aerospace power.

Take off from adversity

If the development of the Chinese aerospace transportation system is compared to an epic "long drama", then the long Erbing Rockets will undoubtedly play an extremely important and meaningful role in it. It also opened the prelude to the rapid development of China's aerospace industry with the dazzling performance since the early 1980s.

The starting point of the tough life of the Long Erbing Rocket is the technical improvement of the Long March 2 rocket development team on the Long March II Rockets many times. Among them, how to improve the rocket's carrier capacity is one of the difficulties that the team focuses on.

The backward design of the early engine shutdown process will cause the rocket to lose capacity of the carrier capacity during the track. For this reason, the development team has designed two solutions, but it is not ideal enough. The Rockets' carrying capacity cannot be lost. At the same time, it is necessary to take into account factors such as research and development funds and development cycles. What should I do? They were not frightened by many difficulties. Researchers responsible for the launch of the track design carried out a lot of calculations on night, and designed the work plan of the two engines. The clever cooperation of the engine shutdown time ensures that the rocket's capacity is not lost.

In addition, the development team combined the situation where my country could only adopt railway transport at that time, maximizing the size of the train carriage, and designed a 3.35 -meter diameter rocket. The value of 3.35 meters has been used as the standard diameter of the Rockets ... In the face of technical difficulties or even experimental failures, the development team has never hit the retreat.

Progress is the iterative process of hard work in solid accumulation. The road has always been twisted, and the journey has been difficult since ancient times. In the first high -level forum of "two bombs and one star" historical research in China, some people wrote in the paper, "After the long march of the Long March 2 was lost, it caused a very passive situation to the entire model team, but the entire team held the pressure on the pressure. After careful analysis and improvement design, after a year of hard work, it was launched successfully on November 26, 1975. The Long March 2 rocket launched four times, laying the foundation of the Long March 2 Cross Rocket. "

Success will never be available at hand, but the most precious crown of fate to the struggler. Behind the glory, the Long March II Rocket Development Team does not know how much grinding has been chewed. The successful development of the Long Erbing Rockets has condensed the blood and tears and sweat of the old Rockets designers of the Rockets.

"From the beginning of the Long March 2 Rockets, to the development of the Long Erbing Rockets, it laid the foundation for the subsequent models. Related information shows that on the basis of the development of the long two -B Rocket, the self -developed technology such as the gradual mature first and secondary heat separation has formed a total of more than 10 models of the Long March series of rockets in my country, which laid a solid for the development of my country's carrier rockets. Base.

The flames of the bears rushed straight into the clouds. From then on, there were no difficulties or frustrations to stop the Erbing Rockets rushing towards the sky. From September 1982 to 1998, the Long Erbing Rockets was awarded the "High -quality Long March 2 Crown Rocket Gold Medal" with a continuous successful launch, becoming my country's first "gold medal rocket" in China. The strength of the long Erbing Rockets proved to the world: China's technical level of independent development of launching rockets has achieved the "accumulation of quantitative" to "qualitative leap".

Representing China to the world

In 1978, my country entered a new period of reform and opening up. At that time, the international commercial launch market was lacking in one -time carrier rockets, and international satellite manufacturers and end users were looking for carrier rockets that could launch satellites worldwide.

Opportunities seem to have no signs, but in fact, people who are always favored and preferred. Long Erbing Rockets have stepped on the stage for the world's commercial launch due to multiple advantages such as mature technical capabilities: in 1985, China signed a long Erbing Rockets with French companies at the Paris International Aviation Exhibition in Paris International Aviation Exhibition. The contract of the French company's micro -gravity testing device, which is the first time that China has provided satellite service for foreign countries, becoming the first sign of Chinese aerospace to enter the international commercial launch market. In 1992, the Long Erbing Rockets successfully equipped the "FREJA" scientific test satellite launched by the Swedish company; from 1997 to 1999, the Long Erbing Rockets successfully launched two "铱" satellite simulation stars and 12 American "铱" satellite ...

"The rocket we developed independently was used to launch foreign satellites." This kind of admiration is proud. In the era when there were few high -tech products in China, the news of the success of the success of foreign satellites made people across the country feel angry. Essence

While breaking the waves in the international market, while continuous innovation, the development team of Chang Erbing Rockets has absorbed beneficial experience from cooperation and promoted the overall improvement of my country's aerospace technology level. In order to complete the plan to launch the stars with the Motorola Corporation of the United States, the development team has carried out various improvement work on the Rockets. The rocket's posture control and precise control of tracking speed control are more accurate. In order to complete the task of launching scientific detection in the international cooperation space detection project, scientific researchers have improved the design improvement of the Long Erbing Rockets, and the rocket's carrying capacity has been greatly improved ... Through the continuous improvement of design Status, take -off quality, low -orbit operation and other aspects have achieved leapfrog development.

From low track to large ellipse orbit, from single -star to double stars, from the main battle Jiuquan launch site to adapting to Taiyuan and Xichang launching grounds, the development of Chang Erbing Rockets has always been accompanied by many practical problems and various risks and challenges. The determination and wisdom of the development team to overcome difficulties, but they inherited and carried forward the spirit of self -reliance, broke through the technical difficulties and accumulated valuable experience.

After decades of development, the reliability of the long Erbing Rockets has been continuously improved, and the technical skills are thick. In the process of continuously upgrading the plan of customer needs, the rocket systems have been optimized; in recent years The development team of the Long Erbing Rockets has prepared a variety of generalized solutions equipped with a variety of satellites in advance to meet the new needs of the commercial space market; by creating innovative measures such as exclusive trains and providing custom services, we will take the lead in the fierce competition in the commercial space market. Native

Guo Wu, deputy commander of the Long Erbing Rockets, introduced, "Now that the customer needs the demand, we can quickly provide a matching plan, which greatly shortens the performance cycle. We will also make corresponding improvements in each task. Rockets' adaptability. "

Forty is not confused. As a pioneer in the field of international commercial launch, the long Erbing Rockets not only represent the past of China's international commercial launch, but also expand the future of the commercial launch field. Guo Wu said, "We will make the Long Erbing Rockets a rocket that is positioned in the market for the launch of the middle and low -oriented satellites, improves the rocket's market competitiveness and strive for more market share."

We have reason to believe that the Almighty "Star pitcher" Long Erbing Rockets will also create new glory in the commercial launch mission at home and abroad in the future.

"Gold Medal" level against "high density"

With the rockets flying again and again, China's aerospace industry is from great to strong. In recent years, my country's aerospace industry has entered a stage of high density launch. In a series of major flight missions, the performance of the Long Erbing Rockets is remarkable, showing the extraordinary strength of the "gold medal rocket" under the pressure of high -density launch.

As the first "gold medal rocket" in China, so far, the Long Erbing Rockets are still the longest high -reliable rockets in the long -term rockets of my country's Long March series, but the long Erbing Rockets are not designed to have any extraordinary extraordinary extraordinary extraordinary extraordinary people. In fact, in order to ensure its launch flight success rate, several generations of developers have contributed a lot of wisdom and sweat.

"For a long time, the development team has a targeted solution to the weak links that affect the success or failure. Fully tried, applied new technologies, and new solutions have kept Chang Erbing Rockets constantly rejuvenating new vitality to increase new skills." According to the introduction, the long Erbing Rockets can maintain high launch power for a long time. In addition to strict control of the quality of production technology, it is more important to continue to carry out reliability growth projects continuously carried out by the Long Erbing Rockets.

In order to ensure that the rocket's pre -shooting status is normal, the rocket parameter detection is added; in order to ensure the safety of the equipment and the product safety of the equipment on the arrow, the inspection and acceptance measures and reliability growth test of related instruments and equipment will be increased. Measures such as heat protection and lightning protection ... Over the years, the development team has made hundreds of technical improvements and improvement on the long -term two -B Rockets, which has continuously improved the rocket's technical reliability.

The impact of the epidemic, the changes in technical status, the shortcomings of the launch field, and the launch of multiple places ... For the long -density launch task, it is difficult to maintain high successful power in high -density launch tasks. How to resolve the development team of Long Erbing Rockets?

The refined quality management work is the "fresh trick" of the long two -B Rocket development team. In recent years, the batch production of the Chang Erbing Rocket has brought favorable conditions for quality control, but the development team has not relaxed the attention of quality control and control. Li Yongmei, the quality director of the Long Erbing Rockets, introduced, "We strictly follow the nodes to conduct rapid analysis of quality problems and the" zero -zero "review to ensure that the subsequent tasks are carried out in time. Measures such as package analysis to pay close attention to the quality of the product and ensure that every task does not have any quality problems. "

In addition, optimize the launch process, effectively reduce the working cycle of the launch site, strictly implement product testing data, focus on the operation that may introduce new risks ... can be described as rigorous from top to bottom, from small to large, from inside to inside to inside The outer city is full, and the long -term two -B Rockets research team has added enough to succeed.

The times are changing, but the development team of the long Erbing Rockets has never changed; technology is changing, but the original intention of the development team of the Long Erbing Rockets has never changed with the original intention of "high quality".

Never stop next

In recent years, the new generation of carrier rockets in my country has appeared frequently. Among the young Long March series of rocket members, people have found that the long Erbing Rockets have not diminished the year. The innovation for new and new. Life with the theme of "growth" is the most long -term, and the growth of the theme of "struggle" is the most exciting. At present, the carrier rocket can be reused and reduced the launch costs, becoming one of the important directions of the research of major aerospace powers in the world. In this field, the development team of Long Erbing Rockets is not allowed. "Safety Control Technology" launches challenges!

This technology is a young developer who is only in his 30s. They are the "fresh blood" of the long Erbing Rockets development team, and they will become the future successor. Adhering to the spirit of self -reliance, they adopt an innovative team collaboration model, break the original barriers of professional rooms, form a assault group, and vowed to break a new way like the older generation of researchers!

"The grid rudder is the first time in my country's carrier rocket, and there is no relevant technology to learn from. The development team has determined the size of the grid rudder through a large number of wind tunnel tests. The transmission grid rudder system and integrated high -performance electrical system. "Ren Yuehui, deputy director of the electrical system of Chang Erbing Rockets, introduced the high -intensity of the development team, from the principle of the device principle on the arrow to the multi -round system matching test, and penetrated into the capital Aerospace Machinery Co., Ltd., Beijing Precision Electromechanical Control Equipment Research Institute, and Beijing Institute of Strong Environment Research Institute, such as follow -up analysis of key components, research work principles and design and manufacturing key points, and conducted a large number of reliability tests. When encountering technical problems, everyone will discuss on the spot, study overtime, and polish every detail ...

In 2019, the Chang Erbing Rockets successfully conducted the first "grid rudder separation area safety control technology" test in my country.

The first "Guiyan" system successfully realized a fixed -point recovery of one -sided grid rudder and rectifier wing umbrella. The first was used to carry satellite controller with excess load. In terms of technological innovation, the young team of the "Gold Medal Rockets" showed whose responsibility and strength to give up, and hatched one after another reliable cutting -edge technology for other carrier rockets.

Nowadays, the development team with a strong innovative atmosphere has also become an important cradle for innovative talents in the aerospace field, and has sent a large amount of fresh blood for the development of the space industry. According to Ren Yuehui, the youth forces from the Long Erbing Rockets have now been active in the development team of rockets in various types of rockets. They have left their struggle at each new journey of the Rockets Dean's series of rockets and carved their wonderful. youth.

Yin Xiaochen was an apprentice brought by Ren Yuehui. When he joined the job, he participated in the launch task of Chang Erbing Rockets. In the atmosphere of innovative vitality and rigorous and meticulous atmosphere in the long Erbing Rocket team, he grew rapidly. Now that he has devoted himself to the development of a new generation of manned carrier rocket, Yin Xiaochen said, "In the team of the long Erbing Rockets, I felt the innovation of aerospace work. , I also always implement the spirit and style of the long Erbing Rocket team into the work, and remind myself to be a member of the "gold medal rocket" team at all times. "

The life of struggle is the most tough, and the journey of dreaming is the most endless.

Over the past 40 years, the Long Erbing Rockets has undergone the test of the times. It has gone through the development process of my country's aerospace industry from difficult to rise to rapid growth, and inherits the spiritual blood of Chinese aerospace with the spirit of "two bombs and one star" as its core. Along the way, the Long Erbing Rockets also became the cornerstone of the confidence of the Chinese nation.
