From God to Shenzhou VI: the ladder from generation to generation-the commander of Shenzhou VI under the leadership of the old marshal

At the moment of witnessing the safe return of the Shenzhou VI spacecraft, as the designer of the Shenzhou I spacecraft to Shenzhou 5, Qi Faren's eyes were fixed.

Two years ago, at the celebration in Shenzhou 5, Qi Faren, who was over 70 years old, said that the complete success of Shenzhou 5's mission was not only the success of China's first manned space flight, but also the success of China's space talent training. Today, Qi Lao's thesis is perfectly interpreted: two years ago, the average age of the chief commander and chief designer of the Shenzhou-5-7 system was 53.6, but two years later, the age of the leader of Shenzhou-6 dropped to 48.7. Among them, Zhang Weiqing, the 44-year-old deputy commander-in-chief of China's manned spaceflight project, Liu Yu, the commander-in-chief of Chang 'e-6 rocket system, Zhang Bainan, the chief designer of Shenzhou-6 spacecraft system, and Shang Zhi, the commander-in-chief of Shenzhou-6 spacecraft system, are all 43 years old ... "Young Shuai" took the lead in Shenzhou-6 flight, which proves that the baton of China Aerospace is being handed over smoothly. Veterans are not old, and novices emerge one after another. Shenzhou spaceship witnessed the pursuit of two generations of astronauts in China for 30 years.

Qi Faren: "I am the third steamed bread"

Since China's first astronaut Qian Xuesen, Qi Faren has been the third generation, and Qi Faren used to call his generation of astronauts "the third steamed bread". It is this third generation of astronauts who have realized China's dream of manned space flight, but Qi Lao has no intention of being greedy. He always said that if one person is eating steamed bread, the third one will be full, but if the first two have no bottom, how can there be only the third one? As the "third steamed bread", Qi Lao is full of respect for Mr. Qian Xuesen and the second generation of heaven and man who stayed in Su Hang.

Some people compare aerospace engineering to building a "ladder", and the builder of this "ladder" is not a team of "people ladders". Standing on the shoulders of predecessors, every generation of astronauts should engage in groundbreaking work. As Qi Lao's name "Origin" represents, the first artificial earth satellite, the first launch vehicle, the first communication satellite, the first manned test spacecraft ... Qi Faren experienced a new starting point for China's space flight again and again.

In the R&D process of shenzhou spaceship led by Qi Faren, there are two moments that cannot be ignored.

One is 1999, the first space trip of Shenzhou I. This was originally an experiment to test a new type of rocket carrying a spacecraft, but relevant personnel put forward the idea of taking the opportunity to carry an experimental spacecraft. Thanks to the efforts of Qi Faren and many scientific and technological personnel, an experimental spacecraft used only for ground electrical performance testing was modified and sent into space! In the eyes of many people, this is an adventure, but as the chief designer, Qi Faren regards it as an opportunity that must be seized. Facts have proved that it was this "adventure" that started China's flying feat.

The other time was in June 65438+1October 65438+June 2003, when Shenzhou 5 returned safely, Yang Liwei met Qi Faren in the welcoming crowd and said, "Thank you, General Qi. The spaceship you designed is so good. " It's just a short thank you, but all astronauts know that everything goes without saying. While the "Shenzhou" kept sending good news, Qi Lao's wife left us forever. Qi Faren consoled his relatives in heaven with the success of China's space industry. "It's not easy to be an astronaut," Qi Faren often said. Being an astronaut requires not only wisdom and perseverance, but also dedication and strength.

Liu: "Supporting my three dreams"

Among the four chief commanders and chief designers of the "Ship" and "Arrow" systems launched by Shenzhou VI, Liu, the 66-year-old chief designer of the rocket system, is the only one who is over 60 years old. In his view, "Shenzhou VI" may be his last battle as the chief designer of the rocket.

Time flies, it has been 40 years since Liu entered the space gate of China. Unconsciously, the young talents of that year have now been infected with frost. However, he has no regrets: "The motivation that supports me to do space career all my life is my' three dreams': when I was a child, I listened to the Goddess Chang'e flying to the moon's illusory' flying dreams'; An' aerospace dream' that explores the mysteries of the universe after work and can't stop; As I grow older, my' dream of a strong country' is getting stronger and stronger. "

Liu is a pioneer in the bundling and separation technology of China launch vehicle. The boosting bundling separation technology he conquered filled the blank of China's launch vehicle bundling technology and made China enter the advanced ranks of bundled launch vehicles in the world. He once created 18 months and took out a brand-new "miracle" of "growing two bundles".

"In my heart, rockets are the most beautiful." Liu Dui said: On June 5438+February 3, 2000/KLOC-0, ten days before the launch of Shenzhou II, the Long March II F rocket was accidentally hit. After expert "consultation", he decided to repair it on the spot. In order to determine the collision process and deformation of the rocket, Liu appeared at the scene day and night, running up and down between working platforms at all levels, repeatedly measuring and calculating the rocket and the platform, and repeatedly studying technical problems with relevant personnel. Just a few days later, the hero's Long March rocket stood beside the launch tower on time. When the Long March rocket successfully completed its launch mission, it said, "Look, what is a gold medal rocket!" Show pride.

Shenzhou VI is not a copy of Shenzhou V. Similarly, the Long March II F rocket is not a simple repetition of the rocket launched two years ago. In the live broadcast on the day of launch, hundreds of millions of viewers witnessed the wonderful moments such as the separation of booster and core rocket through the newly installed image measurement system of rocket. And there are some "secret skills" similar to adding "locks" to the escape system, which most people don't know. "Our generation used the Long March rocket to send satellites into 36,000 kilometers of geosynchronous orbit. I believe that in the near future, a new generation of astronauts will be able to send spacecraft to a lunar orbit of 380,000 kilometers. " Liu's words are exactly what all China people expect.

Shang Zhi: "Problem Solver"

Shang Zhi, the 42-year-old commander-in-chief of Shenzhou VI spacecraft, is the youngest commander-in-chief in charge of this manned space flight, but he has the reputation of "the person who is indispensable for every problem of the spacecraft". During the days when Shenzhou VI roamed the sky, Jiuquan Satellite Launch Center accused Shang Zhi of directing.

"Kung Fu comes home with strict specifications". Over the years, Shangzhi, who graduated from Harbin Institute of Technology, has always kept this school motto in mind.

Calm comes from confidence.

As early as before the launch of Shenzhou-1, Shang Zhi, then the chief dispatcher, changed the old method of posting the work schedule the day before the satellite launch, and compiled the "Eight-hour Work Procedure for Shenzhou-1 Launch Site" to make everyone, every car, every job content and guarantee conditions clear at a glance. This process has become the basis and mode of satellite and spacecraft launch site organization. After Shenzhou VI entered the launch site, he compiled "Shenzhou VI Factory Review Document System Table" and "Shenzhou VI Project Management Plan", including 324 technical documents, and reviewed them one by one. As long as there is an error or missing project, he will start again immediately. In his work, for him, the words "basically meet the requirements" and "basically feasible" are absolutely not up to the requirements and absolutely not feasible.

At the beginning of the first spaceship commander-in-chief, Shangzhi's way of dealing with difficult problems was amazing.

The data bus cable at the bottom of the spacecraft return module was oxidized to "green" because the manufacturer tinned where it should be gilded. After investigation, Shang Zhi urged relevant personnel to collect cables that can meet the needs of the whole world.

Almost at the same time, technicians found that some wires used on the spacecraft had an unexplained indentation at intervals, and some could only be seen with a magnifying glass. Re-routing will delay the launch. Shangzhi decided to screen all the 30-kilometer-long wires in stock like a trawl, and pick the ones without indentation first.

Shang Zhi knows that a spaceship has 80,000 cable network nodes,100,000 components and hundreds of thousands of computer software statements. If a solder joint, a wire, a component or a line goes wrong, it will lead to great disaster.

In order to stabilize the morale of the army and ensure the quality of products, on the eve of the Spring Festival this year, he strictly ordered all the "Shenzhou VI" researchers to return their return tickets! On February 6th, when the work was finished, the Commander-in-Chief had bought air tickets for those who went home to visit relatives and brought holiday gifts to their parents. This makes people feel the heart of this "cold" commander.

Zhang Bainan: "You can't just look at the immediate success."

The flight time is increased from 1 day to 5 days (actually having the ability to fly for 7 days); The number of astronauts increased from 1 to 2; The astronauts on the Shenzhou 5 only operate in the fixed position of the return capsule, while the astronauts have to do all kinds of work during the flight. Astronauts will enter the orbital module for the first time and conduct scientific experiments ... The difference between Shenzhou VI and Shenzhou V is clear at a glance. June, 5438+October, 2004 10, when Zhang Bainan took over the command seal of the chief designer of Shenzhou VI spacecraft system from Qi Faren, it was really a heavy burden for Shenzhou VI to realize "many people and many days" in less than two years.

More than a year later, when Shenzhou VI appeared in front of people, "new ideas come out one after another" made people shine.

First, by improving the bumper, the reaction force of astronauts when landing can be easily resolved; Secondly, improve the hatch, so that astronauts in weightlessness can go back and forth between the orbital module and the return module of the spacecraft, and ensure that the hatch is sealed while opening and closing freely; Third, "decorate" the inner cabin, which not only prevents astronauts from damaging instruments and equipment during exercise, but also prevents astronauts from being injured; Fourth, enhance immunity, reduce the impact of astronauts' activities in the cabin on the flight of the spacecraft, and let the astronauts "go your way" and the spacecraft "I fly my way" ...

"All manned, go all out to ensure success" is the loudest sentence in the spacecraft team. The premise of realizing all this is scientific and technological innovation. China's fourth generation astronauts are writing a new page for them with wisdom.

When Shenzhou VI succeeded again, as the chief designer of a new generation of spacecraft, Zhang Bainan saw further: "My job requires not only to ensure the success of Shenzhou VI, but also to ensure the smooth progress of the project under study. Just look at the immediate success and ignore the future models, and you will be punished. " Zhang Bainan, 43, is as calm as water. In his view, it is related to the future of shenzhou spaceship to make the basic work more solid and build an elite team that can fight hard. "It's hard to say what is impossible, because yesterday's dream can be today's hope or tomorrow's reality." Robert goddard, the "father of American rockets", spoke the voice of all mankind. Today, 80% of China's spacecraft and rocket test teams are young people under the age of 35, who are turning China's dream into tomorrow's reality.
