Qian Xuesen! !

Over time, winter goes and spring comes, and cold and heat suddenly flow easily.

The son of a childe belongs to a poor spring, and the heavy soil is separated forever.

Who wants to obey privately, it is not enough to stay for a long time.

I'm ready to serve, and I'll go back to my original service.

Looking at Lou, thinking about this person, thinking about the experience in the room.

There is nothing on the picture, but there are traces of calligraphy.

The incense has not stopped, but it is still on the wall.

Disappointment seems to exist, and it is difficult to rush back.

Like a bird in the Hanlin forest, it only lives once.

If you swim like a fish in Sichuan, you can see the middle of the road.

The spring breeze came and the morning light slipped from the eaves.

When you forget to sleep, your worries accumulate day by day.

When you are weak, you can still attack.

Qian Xuesen (19 1 1 February1day-June 365438, 8: 06 +0) is a famous physicist and rocket expert.

Hangzhou, Zhejiang, Han nationality,1August, 959, joined the China * * * production party, with the rank of doctor and lieutenant general. He is known as "the father of China's space flight", "the father of China's missiles", "the father of China's rockets" and "the king of missiles". In 2007, he was named as a person who touched China.

1934 graduated from department of mechanical engineering, Jiaotong University, and studied at MIT and California Institute of Technology from 1934. 1935 went to the United States to study aviation engineering and aerodynamics. 1938 received a doctorate from California Institute of Technology. Later, he studied in the United States as a lecturer, associate professor, professor, director of supersonic laboratory and director of Guggenheim Jet Propulsion Research Center, engaged in rocket research.

1950, we began to strive for the return to the motherland. Kimble, then undersecretary of the US Navy, said, "Qian Xuesen is worth five divisions wherever he goes. I would rather kill him in America than let him leave. " Therefore, Qian Xuesen was persecuted by the American government and lost his freedom. 1955 It took five years to return to the motherland.

1955 10 After the continuous diplomatic efforts of Premier Zhou Enlai, Qian Xuesen broke through various obstacles and returned to China, and joined the China * * * Production Party on 1959. He used to be the director of the Institute of Mechanics of Chinese Academy of Sciences, the deputy director of the Seventh Ministry of Machinery Industry and the deputy director of the Commission of Science, Technology and Industry for National Defense. He was the honorary chairman of China Association for Science and Technology.

Qian Xuesen and General Secretary of Hu Jintao Qian Xuesen put forward an extremely important implementation plan for developing rocket and missile technology in China. From April 65438 to April 0958, he served as a technical leader in the development of rockets, missiles and spacecraft for a long time, making great contributions to the development of rockets, missiles and aerospace in China. Qian Xuesen used to be vice chairman of Chinese People's Political Consultative Conference, member of the Department of Mathematics and Physics of China Academy of Sciences, honorary chairman of China Aerospace Society and chairman of China Association for Science and Technology. 199 1 In June, the State Council and the Central Military Commission awarded Qian Xuesen the honorary title of "National Outstanding Contribution Scientist" and the first-class hero model medal.

10 2009 10 3 1 passed away in Beijing at 8: 06 am at the age of 98.

[Edit this paragraph] Personal honor

1999, the Central Committee, the State Council and the Central Military Commission decided to award Qian Xuesen the "Two Bombs and One Satellite Meritorious Medal"; 199 1 was awarded the honorary title of "National Outstanding Contribution Scientist" by the State Council and the Central Military Commission, and was awarded the first-class hero model medal by the Central Military Commission; In 2007, he was awarded "Touched China Person of the Year".

His works include Engineering Cybernetics, Lectures on Physical Mechanics, Introduction to Interstellar Navigation, Systems Engineering, Thinking Science, Geographical Science, Science and Art Science, Humanities and Modern Science and Technology, Creative Systems, Macro-architecture and Micro-architecture, and Communication Collection of the Sixth Industrial Revolution.

[Edit this paragraph] Personal life

Qian Xuesen19 1 1 February11was born in Shanghai. He studied in the middle school attached to Beijing Normal University and Jiaotong University in his early years. 1934 Summer vacation, graduated from Jiaotong University and was admitted to Tsinghua University to study abroad at public expense.

1One day in August, 935, Qian Xuesen left the motherland from Shanghai on a ship of the American Postal Company. The muddy waves of Huangpu River rolled and looked at the gradually blurred Shanghai. Qian Xuesen silently said: "Goodbye, motherland. Now that you're in power, you're in a mess. I went to the United States to study technology and will come back one day to help you revive. "

Qian Xuesen went to the United States to enter the aviation department of MIT, and his academic performance has always been among the best. He had to practice in a factory to study engineering, but at that time, the American aviation factory discriminated against China people, so a year later he began to study aviation engineering theory, that is, applied mechanics. He transferred to California Institute of Technology.

Qian Xuesen came here with admiration. Because, located in the aviation department of California Institute of Technology in Pasadena, a suburb of Los Angeles, there is a famous aerodynamics professor von Carmen, who is Hungarian. But later, Qian Lao himself may not have thought that he could become a student of Professor von Carmen, and become one of the best and promoted to his best assistant.

In the early 1930s, aviation science was still in its infancy. Von Carmen was a top figure in this field at that time, and was later known as "the father of supersonic flight". 1970, there was a crater on the moon named after him.

Von Carmen looked at the serious and short young man carefully. He asked several questions for Qian Xuesen to answer, and Qian Xuesen answered all his questions after a little thought. Von Carmen secretly praised: This China man is witty and full of wisdom. He accepted the student happily. At the beginning of 1945, Qian Xuesen became a member of the air force scientific advisory group headed by von Carmen. After Germany surrendered, he went to Europe with the investigation team of the regiment to inspect aviation and rocket technology. 1947 At the beginning of this year, 36-year-old Qian Xuesen became a full professor at MIT. During the monitoring period, apart from teaching, he still did not give up academic research. 1953 published "Take-off from Earth Satellite Orbit", which laid the foundation of small thrust flight mechanics. 1954 published "Engineering Cybernetics". 1955 when saying goodbye to von Carmen before returning to China, von Carmen said excitedly, "You have surpassed me academically now!"

Qian Xuesen became a graduate student of Guggenheim Aviation Laboratory led by von Carmen. This laboratory later became the cradle of American rocket technology, and Qian Xuesen was one of the first three members to conduct rocket technology research here.

1935 to 1939 studied in the department of aeronautical engineering of MIT and obtained a master's degree. 1936- 1939 studied in the department of aeronautics and mathematics of California Institute of Technology, USA, and obtained a doctorate. 1939- 1943, researcher, Department of Aeronautics, California Institute of Technology. 1943 to 1945 was an assistant professor in the department of aeronautics, California Institute of Technology (1940 to 1945 was a communication researcher in Chengdu Institute of Aeronautics, Sichuan). 1945- 1946, associate professor, Department of Aviation, California Institute of Technology. 1946- 1949, associate professor and professor of aerodynamics, Department of Aeronautics, Massachusetts Institute of Technology. 1949- 1955, Director and Professor of Jet Propulsion Center of California Institute of Technology. Married Jiang Ying on 1947.

1955 returned to China. 1955 to 1964, director and researcher of the Institute of Mechanics, Chinese Academy of Sciences, and director of the Fifth Institute of the Ministry of National Defense. 1965 to 1970 served as deputy minister of the seventh Ministry of Machinery Industry. 1970 to 1982 served as deputy director of the science and technology Committee of the commission of science, technology and industry for national defense and vice chairman of the China association for science and technology. He has served as the first and second director of China Automation Society, honorary president of China Aerospace Society, China theoretical and applied mechanics Society and China Systems Engineering Society, executive director of the Presidium of China Academy of Sciences, and member of the Department of Mathematics and Physics. 1986 to 199 1 May, served as the chairman of the third National Committee of China Association for Science and Technology. 1991may was elected honorary chairman of China association for science and technology at the fourth national congress. 1April, 1992, was appointed honorary chairman of the Presidium of China Academy of Sciences. /kloc-0 was elected as an academician of China Academy of Engineering in June, 1994.

Qian Xuesen is an alternate member of the 9th to 12th CPC Central Committee and vice chairman of the 6th, 7th and 8th CPPCC National Committee.

A bumpy trip to China

"On the way back to China with 1955 and Qian Xuesen's family, I always believed that I would be able to return to my motherland. Today, I finally came back! " Under the care of Premier Zhou Enlai, Qian Xuesen, a famous scientist and rocket expert in China, set foot on his way home on September 1955, arrived in Hong Kong on September 10/955, and arrived in Guangzhou on October 8 1955. He returned to China with his wife and two young children.

1In August, 935, Qian Xuesen went to the United States to study and study aviation engineering and aerodynamics as a public student. Before returning to China, he was the director of the California Institute of Technology Supersonic Laboratory and the director of the Guggenheim Jet Propulsion Research Center. Qian Xuesen 1935 went to study in the United States. 10 years later, he became a first-class rocket expert at that time. It is famous for its amazing rocket theory that "a rocket with a speed of 10,000 kilometers per hour has become possible". During World War II, Professor Von Carmen of California Institute of Technology and his tutor participated in the research and development of missile nuclear weapons, which was the top secret Manhattan project of the United States at that time. He was one of the few rare talents in the United States.

When the news of People's Republic of China (PRC)'s birth reached the United States, Qian Xuesen and his wife, Jiang Ying, could not restrain their inner joy and discussed returning to China to serve the motherland as soon as possible. At this time, the United States, led by McCarthy, conducted a comprehensive investigation on the producers of * * *, and set off a hysterical frenzy in the United States that drove employees to be loyal to the US government. Qian Xuesen's certificate to participate in confidential research was suddenly revoked by the US military department because he was suspected of being a producer of * * * and refused to expose his friends. This made him very angry. Qian Xuesen asked to return to China on this ground. However, Qian Xuesen never imagined that his willingness to return to China turned into a disaster! "He knows all the core secrets of the U.S. missile program," said the U.S. undersecretary of the Navy. One Qian Xuesen is worth five marine divisions. I'd rather shoot this guy than let him go back to Red China! "

Since then, the political persecution of him by the United States has followed. Immigration raided his home and detained him in Temina Island for 65,438+04 days. He was not released until he received a huge bail of $65,438+$5,000 from California Institute of Technology. Later, the customs confiscated his luggage, including 800 kilograms of books and notebooks. They insisted that there were confidential materials in it. In fact, Qian Xuesen had handed them over for inspection before packing them. After reviewing all his materials again, the American prosecutor proved that he was aboveboard.

The news that Qian Xuesen was persecuted in the United States soon spread to China, and New China was shocked! Friends in domestic scientific and technological circles support Qian Xuesen through various channels. The Central Committee of the Communist Party of China is extremely concerned about Qian Xuesen's situation in the United States, and the China government publicly issued a statement condemning the US government for imprisoning Qian Xuesen against his will.

When Qian Xuesen's request to return to China was unreasonably blocked by the United States, China also detained a group of Americans, including American nationals detained by the China administration in violation of China laws and American soldiers detained by the China administration in violation of China's airspace. The U.S. government is eager to get back these Americans detained by me, but it is unwilling to have direct contact with China.

1954 in April, the United States, Britain, China, the Soviet Union and France held an international conference in Geneva to discuss the settlement of the Korean issue and restore peace in zhina. Zhou Enlai, head of the China delegation attending the meeting, thought that a group of overseas students and scientists in China were detained in the United States, so he instructed that since the Americans asked British diplomats to dredge relations with us, we should seize this opportunity and open up new channels of contact.

On June 5th, Wang Bingnan, Secretary-General of the China delegation, held a preliminary discussion with US representative and Deputy Secretary of State Johnson on the nationals of the two countries. The United States submitted to China a list of overseas Chinese and some American soldiers detained by China, asking China to give them a chance to return home. In order to show China's sincerity, Zhou Enlai instructed Wang Bingnan to make generous concessions in the third meeting between China and the United States on June 15, and demanded that the United States stop detaining Qian Xuesen and other China students studying in the United States.

However, China's just request was unreasonably rejected by the United States. On July 2 1 day, the Geneva meeting closed. In order not to interrupt communication channels, Zhou Enlai instructed Wang Bingnan and the United States to hold consular talks in Geneva from July 22nd. To further demonstrate China's sincerity in the Sino-US negotiations, China released four detained American pilots.

China's high-profile attitude is ultimately to let Qian Xuesen and other scientists studying in the United States return to China as soon as possible. But on this key issue, Americans cheated. Despite more than 65,438+00 contacts between China and the United States, American representative Johnson insisted that China could not give the real reason why Qian Xuesen wanted to return to China.

Just as Premier Zhou Enlai was anxious about this, Chen Shutong, then vice chairman of the National People's Congress Standing Committee (NPCSC), received a letter from the other side of the ocean. He opened it and signed it "Qian Xuesen". He couldn't help feeling a shock. He finished reading the letter quickly. The content of the letter was originally to ask the motherland government to help him return to China.

This letter was written by Qian Xuesen on a small cigarette paper and sent to his relatives in Belgium at that time, and sent to Vice Chairman Chen Shutong. For such an unusual overseas letter, Chen Shutong knew its weight and gave it to Premier Zhou the same day. "This is really great, and it can completely refute the lies of the US government!" Premier Zhou Enlai immediately made careful arrangements, instructed the Ministry of Foreign Affairs to give this letter to Wang Bingnan, who was holding ambassadorial talks between China and the United States, and instructed Wang Bingnan: "This letter is very valuable. This is irrefutable evidence that the American authorities are still preventing China citizens from returning to China. You should use this letter to expose their lies in the negotiations. "

At the beginning of August 1 China-US ambassadorial talks, Wang Bingnan took the lead in saying to Johnson: "Mr. Ambassador, before we start the discussion, I have been ordered to inform you of the following news: On July 3 1 China decided to release1American pilots including Arnold Wei in advance according to China legal procedures, and they have already arrived in. I hope that this measure taken by the China government will have a positive impact on our talks. " When it comes to Qian Xuesen's return to China, Johnson still repeats the same old tune: "There is no evidence that Qian Xuesen will return to China, and the US government cannot force orders!" Therefore, Wang Bingnan flashed Qian Xuesen's letter to Chen Shutong, and confidently retorted: "Since the American government issued an announcement as early as April 1955, allowing scholars studying in the United States to travel freely, why did Dr. Qian Xuesen, a scientist from China, write to the China government for help in June? Obviously, the request of China scholars to return to China is still blocked. " Johnson was speechless before the facts. The American government had to approve Qian Xuesen's request to return to China. 1On August 4, 955, Qian Xuesen received a notice from the US Immigration Bureau allowing him to return to China.

1955 September 17, Qian Xuesen's dream of returning to China has come true! On this day, Qian Xuesen, with his wife Jiang Ying and a pair of young children, finally boarded the ship "President Cleveland" and embarked on the journey of returning to the motherland.

Thanks to Qian Xuesen's return to China, China's missile and atomic bomb launches were at least 20 years ahead of schedule.

[Edit this paragraph] The interaction between Mao Zedong and Qian Xuesen

Look at Mao Zedong first.

1956, Juxiang Bookstore.

"Chairman," Zhou Enlai said with a big smile after entering the door, "I invited your long-awaited VIP!"

"ah! Comrade Qian Xuesen, "Mao Zedong stepped forward and stood beside Zhou Enlai, clutching Qian Xuesen's hands. He was a little stiff and nervous. "I have been looking forward to you for a long time! The founder and rocket expert of our engineering cybernetics! "

"I have long wanted to meet the chairman," Qian Xuesen excitedly looked at Mao Zedong, who clasped his hands. "I'm afraid you're too busy to bother."

"What you said is just the opposite! I didn't go back to China until I considered you. There are too many things to deal with and I dare not meet too early. " Mao Zedong said sincerely.

"I heard that Americans regard you as a fifth teacher!" Mao Zedong held out five fingers, "I see, for us, you are much more powerful than five divisions! I am now studying your engineering cybernetics to guide China's economic construction! "

Mao Zedong's approachability reduced Qian Xuesen's formality and nervousness when he first arrived.

"Comrade Xue Sen," Mao Zedong looked at Qian Xuesen, "I have carefully read your opinion on the establishment of China's national defense aerospace industry. Well written! "

"Madam President," Qian Xuesen smiled humbly, "I just returned to China and don't know much about the domestic situation. I just put forward many immature opinions on China's national defense construction, especially the aviation industry construction, based on my engineering cybernetics, and there must be many mistakes! "

Mao Zedong waved: "Comrade Xue Sen, how can it be wrong to put forward so many good suggestions? This is very rare! These incisive and original suggestions can only be put forward by you, the founder of engineering cybernetics! "

Mao Zedong paused and then said, "Our country has decided to organize all disciplines and departments to work hard on missiles according to your engineering cybernetics. Comrade Xue Sen, I'd like to invite you, the founder of engineering cybernetics, to take the lead. Do you have confidence? " Qian Xuesen was a little nervous: "Chairman, I'm afraid I can't do such an important task well!"

"Nothing is difficult in the world, as long as you are willing to climb." Mao Zedong waved heavily in the air with chopsticks. "You Qian Xuesen are the originator of engineering cybernetics, and you are afraid that you can't do it well!"

Influenced by the majestic momentum of Mao Zedong, Qian Xuesen finally nodded firmly: "Chairman, I will work hard."

Solve Qian Xuesen's ranking

Nie took the list and hurried to Juxiang Bookstore.

"Madam President, in order to win the Soviet Union's assistance to China in launching missiles and rocket technology, we are going to send people to the Soviet Union for negotiations. What do you think of the list of delegates? "

Mao Zedong thought for a moment and said, "Mr Nie, you should be the head of this delegation. Your delegation should include new weapons and military technology and equipment, as well as personnel from the atomic energy industry. Comrade Xue Sen should also go, and many problems can only be solved if he goes. "

"We are also considering inviting Comrade Qian Xuesen to join our delegation. However, the Soviet Union participated in the negotiations with the positions and ranks of both sides. " Nie Rongzhen solemnly said to Mao Zedong, "Our comrade Qian Xuesen is now the president of the Fifth Hospital of the Ministry of National Defense, and he has no rank. In order to be on an equal footing with the Soviet side, Comrade Qian Xuesen must solve the problem of rank. " After a pause, Nie went on to say, "We asked Comrade Ryan about this problem. Comrade Ryan said:' More than ten years ago, Qian Xuesen was awarded the rank of colonel by the United States. Why can't our producer make him a general? I think Comrade Qian Xuesen has a great responsibility and is the founder of the world engineering cybernetics. As far as his qualifications and contributions are concerned, he should at least be awarded the rank of lieutenant general. Go back and discuss this matter with Mr. Peng, and hold a military commission meeting when necessary, and I will take part in it to finalize the matter. " "

Mao Zedong thought for a moment and said, "Comrade Ryan is very thoughtful. I think that Comrade Qian Xuesen, as the founder of engineering cybernetics, should at least be awarded the rank of lieutenant general. "

In this way, as a scientist and founder of engineering cybernetics, Qian Xuesen, wearing a majestic sky-blue general uniform and a solemn rank of lieutenant general, participated in the Sino-Soviet advanced military technology negotiations with the approval of Mao Zedong.

Talk about engineering cybernetics together

"Well, according to Comrade Qian Xuesen's engineering cybernetics, what is the first missile and satellite test base in China?" Mao Zedong asked with concern.

"The base has been selected, but the candidates for the base leadership team have not yet been decided."

"Please ask Qian Xuesen, the founder of engineering cybernetics, to be the team leader!" Mao Zedong's palm lightly pressed on the chair.

"good!" Zhou Enlai nodded and handed the materials in his hand to Mao Zedong. "This is a report written by scientists like Qian Xuesen according to engineering cybernetics. Please read. "

"This is a heavenly book written by a scientist like Qian Xuesen!" Mao Zedong said humorously, "I must have a good look."

After Zhou Enlai left, Mao Zedong immediately opened the "gobbledygook" handed by scientists such as Qian Xuesen. After reading it, Mao Zedong couldn't restrain his inner excitement. He picked up the direct dial phone and said excitedly, "Well, I want to call a meeting to listen to the report of scientists like Qian Xuesen in person."

In the afternoon, Mao Zedong's Juxiang Bookstore was packed with distinguished scientific guests he invited. "Comrade Xuesen, come, come, sit here." Mao Zedong pointed to a seat next to him. "Please talk about rockets and missiles according to your engineering cybernetics!" Mao Zedong obviously has a special interest in rockets and missiles built by Qian Xuesen under the guidance of his engineering cybernetics.

"Very good." Qian Xuesen nodded slightly to Mao Zedong. "Madam President, I would like to talk about my personal shallow views in this regard. On the issue of rockets and missiles, if the Soviet Union abides by the agreement we signed and the models they provide arrive as soon as possible, we will make a big breakthrough in three to five years and strive to hit the first missile. Because our research on engineering cybernetics is far ahead of them, and the development of rockets and missiles can't be separated from engineering cybernetics anyway. It can be said that without engineering cybernetics, the development of rockets and missiles will be difficult! If they delay, we are not afraid. At least we have the theoretical basis of rockets and missiles and a relatively perfect engineering cybernetics as a guide. The key now is the fuel problem of the rocket. What the Soviet Union promised has not arrived yet. "

Mao Zedong looked at the side of Zhou Enlai and frowned.

Qian Xuesen didn't notice Mao Zedong's expression, and then said, "According to the theory of engineering cybernetics, we are going to make drawings and models first, and take out our own things without relying on foreign aid. As the Prime Minister said just now, when we engage in rocket missiles, including satellites, we must be mentally prepared according to the domestic situation. Of course, the most important thing here is the strong cooperation of the whole country to make the research of engineering cybernetics more perfect. "

Hearing this, Mao Zedong was very excited and interjected, "Comrade Xue Sen, you speak very well! Now we are engaged in cutting-edge technology, and we are also fighting a tough battle, a tough battle of engineering cybernetics! In the past, we won the three major battles of Liaoshen, Ping Jin and Huaihai because we used the strategic thought of "concentrating superior forces and dividing them one by one". "Comrade Xue Sen, in fact, this is also the military application of your engineering cybernetics, but there was no such term at that time!"

Qian Xuesen said with a smile: "So, the chairman should be the founder of engineering cybernetics!"

Mao Zedong waved: "I just unconsciously used your engineering cybernetics in the war. Of course, the founder of engineering cybernetics is still you! How can I be greedy for my own credit! "

……

1960, the Soviet union withdrew all the experts who assisted China, and tore up all 257 scientific and technological contracts, including those that provided us with samples of atomic bombs, rockets and missiles.

1June, 960 10, that is, only 17 days after the Soviet experts left China. Under the leadership of Qian Xuesen and the guidance of engineering cybernetics, China's first short-range ballistic missile was launched with domestic fuel and hit the target accurately. More than a month later, domestic short-range missiles were launched one after another, hitting the target with high accuracy. ...

1964 10 10/6, China exploded its first atomic bomb! Mao Zedong was particularly happy. He has always opposed celebrating his birthday. This year, he made an exception and invited everyone.

Before the banquet, the staff drafted a list of attendees for Mao Zedong's approval. After reading the guest list of three tables, Mao Zedong solemnly crossed out Qian Xuesen's name from another table to his own list. And let Qian Xuesen sit next to him.

The banquet began in a festive atmosphere. Mao Zedong sat in his seat and said with a smile; "Please talk about it today, mainly because our atomic bomb exploded and our rocket test was successful. We China people are more emboldened to speak in the world! " Then, Mao Zedong changed the subject, pointed to Qian Xuesen beside him and said humorously with a smile: "Let me introduce our Comrade Qian Xuesen, who is our king! What king? The king of engineering cybernetics, the king of rockets! His king gave an order with engineering cybernetics, and our rocket went to heaven, so if you want to go to heaven, please find our' engineering cybernetics king' and' rocket king' Comrade Qian Xuesen! "

Mao Zedong went on to say: "Xue Sen, the king of engineering cybernetics, has also set another example for us! He doesn't want the manuscript fee, and he doesn't take the bus to do private affairs. This is good! "

Qian Xuesen was unprepared and never thought that Mao Zedong would praise himself so much on this occasion.

"Chairman," Zhou Enlai said to Mao Zedong, "Comrade Qian Xuesen has one more important thing to learn."

"This is Comrade Xue Sen's cultivation and trust in young people." Zhou Enlai told Mao Zedong the following story.

1In the summer of 964, a rocket designed by Comrade Qian Xuesen had entered "15 minutes to prepare", just waiting for the arrival of "zero hour". At this time, a serious situation that no one had estimated beforehand suddenly appeared. Because the weather is too hot, rocket propellant expands violently at high temperature. It is impossible to inject enough fuel into the missile fuel tank, and the injected fuel is vaporized, which will seriously affect the range of the rocket.

Demonstrations and seminars were held one after another, but no suitable plan was found.

Suddenly, a young engineer named Wang Yongzhi suggested: "Propellant should be released properly!" Everyone is confused by this plan.

"no! No! " The chief designer shook his head repeatedly. "It is precisely because the temperature is too high and the propellant is added less that the problem of not reaching the range is caused. Now you propose to reduce the propellant. Isn't this closer? "

"Discharging a small amount of propellant," Wang Yongzhi insisted, "lightened the weight of the shells. This will not only affect the launch distance of the rocket, but also fly farther. "

"I will never agree to take risks with the property of the country!" The chief designer blocked the door completely with a wave of his right hand.
