China's flight launch success rate is among the world's leading leaders. China has created one of the world's miracles with its amazing flight technology and daring space spirit.
Shenzhou series spacecraft, Chang'e series lunar exploration satellite, Tiangong space experiment station, astronomical Mars probe, Beidou satellite navigation system and Long March series carrier rocket are the overall layout of the mainland space industry.
。
However, the development of China Airlines has not been smooth. Even missing twice in a month. If it's just once, it's a fluke, but it's a little strange that the time between the two defeats is so close.
In this regard, some Confucians said that this is not a coincidence, and it cannot be denied that the US Space Force is suspected of ghosting. What happened to these two failures?
Is the problem really caused by the United States?
March 16, 2020 was the first flight of the Long March 7A carrier rocket.
The Long March 7 developers sat in the monitoring room, paying attention to the various test indicators of the Long March 7. Unfortunately, the Long March 7 failed.
The long 7 March was full of hope. If the test flight is successful, it will become an important force in the history of China's future launch vehicles. Some even predict that China's space launch mission will be carried out by this carrier-based aircraft.
After the failure of the seven flights of the Long March, netizens had different opinions about the reasons for the failure. Many enthusiasts who are concerned about the aviation industry have begun to analyze the causes of the failure and the subsequent impact.
Details are as follows:
The first is that the rocket second stage engine is not working, the second is that the rocket first stage booster does not work, and there is also an assumption that the rocket third stage engine does not work. One question. Whatever the reason, the March 7 defeat of the pickup was fatal.
If the rocket booster engine fails, it means that the fuel transportation method of the Long March 7 cargo spacecraft will not work, and the space station will not be able to get better rocket fuel transportation in the future.
If there is a problem with the rocket's first booster or third stage engine, it will also greatly affect the development and launch of the Long March 3, which is on the same line as the Long March 7. The Long March 3 launch is less than a month away.
On the evening of April 9, the Long March 3B carrier rocket launched as scheduled, but about two to three seconds after contact with the launch vehicle, the rocket began to show abnormalities. The missile deviated from the launch trajectory and turned to the right, causing the missile to hit a nearby mountain and quickly land.
The accident killed 6 people and seriously injured 57 others. Due to the heavy casualties, the incident quickly spread internationally, and some Western media even underestimated the development of China's space industry.
The lead designer of the Pika Märts3 put all his heart and soul into the smooth flight of the Pika Märts3. The "final speed control" scheme proposed by the Long March 3 was adopted by the Long March 3, and in order to improve the hit rate, he also used the method of cryopropellant and added four boosters. I thought the Third Long March would be a milestone, but it turned out to be a disaster.
The international community attacked not only China's aviation industry, but also Academician Long Lehao, questioning his professional level and academic ability, and denying Academician Long Lehao's previous successful research and development.
Academician Long Lehao suffered greatly from the poor guidance of public opinion.
However, academic Long LehaoChina's aerospace should be humiliated and rewarded.
On May 5, the Long March 5B, a carrier rocket specially developed for the mainland space station project, successfully made its first flight. The successful launch of the rocket is a major breakthrough in the technology of the continental space station.
Those who think China's space industry will collapse because it allowed China's space technology to reach the world's highest level again in less than a month, once again demonstrating China's strength.
Taking this opportunity, the head of the Chinese space station answered the reasons why China's space industry suffered two failures in one month, answered the public's concerns about the space industry, and showed the demeanor of China's space industry. The industry is on its way.
When explaining the cause of the accident, the commander only stated that the root cause had been found, but given the secrecy of the strategy at that time, he did not disclose the specific cause in more detail, only the process.
Finding the cause is definitely not smooth sailing, but a process of zeroing in day and night.
The so-called zeroing is to find and solve problems from the technical and management levels, and fundamentally prevent the occurrence of problems. It is necessary not only to examine whether the rules and regulations are working as they should, but also to find solutions to existing problems.
The cost of zeroing is very high, which means troubleshooting from start to finish, manufacturing faults and simulating the cycle of problems in other facilities, and finally finding the cause of the problem.
Although the official reason for the failure two or three years ago has not been disclosed, this failure has become a "sharp sword" in the minds of Chinese astronauts and Chinese people, and astronauts will always be remembered in every scientific research.
。 Job.
Of course, some Russian experts also suggested that the failure of the two Chinas was due to the "unique trick" of the United States, organizing suitable spies to deliberately fire jammers nearby, or using chips imported from abroad to jam China. Destroy the chip.
It is widely believed that China's space industry began in 1956, only a few decades from today, but it has rapidly surpassed developed countries and achieved achievements that have attracted global attention.
Especially after entering the 21st century, the Shenzhou series of rockets have been successfully launched, and China has sent astronauts into space.
China also became one of the third countries in the world to send humans into space. The Chang'e series successfully explores the mystery of the moon. , Tiangong and astronomy provide the technical basis for people to understand extraterrestrial life.
Space station pilots live in space, communicate with people on Earth, monitor real-time scenes in space, and transmit primary research data back to China, which is ideal for the development of the space industry.
The United States has absolute superiority in the field of spatial positioning systems, which they often use to interrupt the pace of technological development in China. The successful development and use of Beidou satellite navigation proves that Chinese can also achieve independent research and development.
Especially recently, the Biden administration has imposed a severe embargo on Chinese chips. Countless scientists are at the forefront of research, hoping to break through the bottleneck of the chip industry and enable China to independently develop its aerospace industry.
At present, a phenomenon has gradually emerged in the mainland aerospace science and technology research team, that is, the age of the team is getting younger and younger, and more young people have become the key figures of the R&D team and R&D. The team is constantly evolving. The development of China's space industry. If China's aviation industry wants to continue its honor, it must cooperate in the following aspects.
First of all, we must establish a correct concept of advantages and disadvantages.
China's space does not mean that every first flight has to be successful.
Although tens of thousands of times have been rehearsed and imposed, during the actual launch, due to some uncontrollable weather or small details, people have left a serious impression.
But now the domestic situation is more complicated, and the contradictions between countries are very obvious. Western countries regard China as an "imaginary enemy" and target China everywhere in international relations, hoping to hinder China's development.
In particular, the United States followed the example of the Soviet Union in its treatment of China, using the power of the media to attack China, destroying and destroying the spirit of the people from within through cultural infiltration.
Aviation powers determine China's international influence and are the emotional and psychological nourishment of many people. If Chinese aviation fails, Western countries will spread rumors that are not conducive to national unity and destroy the self-confidence of Chinese people. What we have to do is to calmly accept the successes and failures in the development process, do not be too arrogant about success, face failure, summarize the experience and lessons of failure, and provide reference experience for the next stage of development. Develop.
Second, young people should see the true face of Western groups.
Western countries often invite graduates of famous Chinese universities to study abroad for higher education. After graduation, Chinese students have some good treatment conditions to stay abroad, but Chinese students are not allowed to interact with the core.
Science and technology only serve the motherland for Chinese students.
Some insecure Chinese students are blinded by short-term gains. After finishing his studies, he landed a relatively cheap scientific job abroad, only to throw away everything he had learned.
Compared with Qian Xuesen and other scientists of the older generation, they overcame unimaginable difficulties, used their lessons to emulate the motherland, resolutely said "no" to the temptation of Western countries, and finally contributed to China's space industry.
Play a breakthrough role.
Chinese youth should be less useful, understand the real purpose of the Western bloc, take the development of the country as the main goal of learning, and be ready to serve the development of the country, not exclude them. Be touched by some genuine interest.
Third, the state should strengthen support policies for scientific research talents.
Researchers and staff involved in aviation take a long time to deal with it.
Every time, Western countries have launched a "talent war" with the mainland, luring Chinese scientists with some unreasonable conditions.
In this regard, in addition to strengthening the patriotic spirit of scientific researchers, our country should also strengthen the support policy for scientific talents, so that scientific researchers can do a good job without it. Apprehension.
●○Conclusion○●
A distinctive feature of China's space industry is its short life span but rapid development.
For a hundred years, it has achieved what Western countries have achieved for hundreds of years. China's space industry can achieve today's achievements not overnight, but the result of the joint efforts of countless astronauts.
Looking back at the establishment of the Chinese Air Force during World War II, countries lacked pilots with mature flying capabilities, and still needed the help of the United States and the Soviet Union in terms of talent.
Successfully formed its own Air Force.
Even in the 21st century, when the space industry conducts thousands of tests and then flies again, there are two major failures per month.
The adverse effects of this would cause serious damage to the mainland space industry.
The purpose of studying the setbacks in the development of China's aerospace industry is to fully understand today's achievements, let the Chinese people see the reality more clearly, and remind people to respect the hard-won achievements.
Today, aviation and deep-sea engineering have become the wings of national development. The continent is committed not only to becoming a world power in military and economic power, but also to not being surpassed in both.
China stands proudly among the nations of the world.
In the days to come, China will continue to develop, and the Chinese people will continue to work hard. Only in this way can China catch up with European and American countries and gain the status and status of a world power.
