40 minutes before launch, Zhang Feng, a rocket power system operator, took a photo of himself with the rocket before leaving the position. This is one of his habits. "Each time the launch, the rocket is just like its own child, reluctant to give up, and must let it go." Zhang Feng laughed, this is his experience of sending hundreds of rockets to heaven.
at noon, Zhang Tongtong, a one and a half year old son of maple, saw the bright tail flame of the rocket on TV. The little guy stared at his eyes and jumped up and down, and it was very excited.
the power system of one of the nine rocket systems. The four - level military commander, Zhang Feng, is responsible for the testing and installation of the pyrotechnics, the inspection of all arrows, and the fuel injection. "This is a position that can not be careless." For 12 years, he kept telling himself that.
Zhang Feng, a 33 year old
1998, Zhang Feng became a new recruits of the Taiyuan Satellite Launch Center launching test station, and after a year and a half year and a half, the Navy Sergeant school was awarded to the naval Sergeant school, majoring in mechanical processing.
in the old teaching and research section of the school, Zhang Feng worked with lathes, electric welding, pliers and spanner for two years. Bitterness was his deepest impression of the two years. "At that time there was a slip of the tongue, the fitter was tired, the welder was bitter, and the electrician was two hundred and fifty." He laughed and said, "I have all these things!"
learn the clamp hours, and Zhang Feng has blisters on his hands every day. When he studied electric welding, his eyes were like sand, which hurt him, and his legs were burnt to holes. When he learned to lathe, he wore aprons all day, and all kinds of workpieces were pulled out according to the drawings. The grease stains in his fingernails could not be washed away.
that's what he doesn't have. One day, the teacher said to him, "we will have a professional qualification examination immediately. I think you are so hardworking that you can report it to an intermediate level." On the day of the exam, Zhang Feng handed in seventh pieces of work and waited for a week. The result came out. He simply opened the flowers.
when everyone can get two intermediate certificates to burn high fragrance, Zhang Feng got four senior certificates in car workers, welders, electricians and fitter, and more than 2000 students in the same period have only three or four people. Not only that, he also won the second runner up in the professional skills competition. "Two years of bitterness do not eat!" At this point, Zhang Feng made a summary of it satisfactorily.
soon, these hardships will come in handy.
take a look at the end of Zhang Feng
2002. After graduating from the military academy, Zhang Feng became the operator of the launch test station power system. When he first arrived, he was full of fog and did not know what his job was. When the rocket lifted off, the old leader pointed to the rocket's flaming ass and said, "this is your job!"
this is, of course, a joke. Soon, Zhang Feng became very hot, because he found he knew nothing about the rocket's butt. The huge and precise liquid rocket engine system has daunting him and made him curious. In fact, this system involves seven major fields, and each professional book is only slightly thinner than the "Ci Hai".
half a year later, with 4 advanced certificates and detailed operating documents, Zhang Feng is competent for some work, such as installation of pyrotechnics, for ground supply. "But there are some things I can only stare." Zhang Feng enumerated that he could not read the electrocardiogram data on the test instrument. He did not dare to touch the complicated pipelines and components on the engine.
"when I was 20, I was worried, and I was playing chicken blood all day." Zhang Feng bit his teeth and sat in his office and opened the principle of liquid rocket engine design. In those years, the base rocket launch mission density was not high, which provided Zhang Feng with sufficient learning time. He was in the office all day, and the leader could receive every call. As time went by, the leader knew what he was studying. Later, at a meeting, the leader raised his voice and said to everyone, "look at somebody else, Zhang Feng!"
earlier, he became interested in the seven tube connector. The seven pipe connector is a connecting device for transporting gas to the rocket. When the arrow is operated, it needs to wear a gas mask. Once the fuel leakage occurs, it can react quickly. Over time, Zhang Feng discovered a problem: "once a fuel leak occurs, we can't see the equipment at all. How can we operate it?" So he began to practice his eyes. Soon, he knew the interface and grooves at the top, at the cost of several times when he was injured when he was dismantled and assembled.
2011 in December, an hour before the launch of a special task, the rocket engine seven tube connector fell off. Zhang Feng, who was on standby, quickly wore gas masks and gloves and lifted the connectors to quickly fit the socket on the arrow. The Yellow fuel vapour immediately spurted from the two manometer, "like the smell of rotten eggs and dead hairtail". Zhang Feng could not see him at all. He felt the operating area, quickly jammed and tightened the locking nut, and the whole process was less than 30 seconds. After watching the curtain on the screen, the applause burst through the command hall. "I didn't think it was a real use." To mention this, Zhang Feng was a little laughable.
from then on, he became the "quality guard" in the station. In a few years, Zhang Feng revised and perfected more than 100 operational procedures for the rocket power system and wrote 13 scientific papers.
the Post 80
test of explosive devices is one of Zhang Feng's priorities. The size of the watch disk is a 42 - kilo - kilo component, which is distributed in the power system, performs the ignition of the engine, and separates the arrow between the one or two and the three levels.
explosive devices must be subjected to rigorous and complex testing before installing the arrow, so as to ensure foolproof. Each rocket should be equipped with several different types of initiating explosive devices, which means that the pre test is a high intensity repetitive labor. "It's really important. Even if you test a problem at a time, it's probably a launch accident. You need to be careful at all times."
"but to be honest," he smiled, "sometimes it's really boring, so I have to sit on the bench." He said that in the 12 years he came to the technical room, he had already installed more than 7000 fire products.
7000 has been tested many times, but the accident happened only once.
2013 June 26th, a major space launch mission on the eve. As usual, Zhang Feng is responsible for the testing of initiating explosive devices. He wore an antistatic clothing and picked up a ignition kit, which is one of the core components of the rocket engine. If you compare a rocket to a car, the ignition kit is equivalent to a spark plug.
"the appearance of the kit was normal at that time." According to the process, Zhang Feng put it in his ear and shook it lightly, "no voice." He carefully placed the kit in his hand, "feeling a little lighter". "I thought there was no medicine at that time." Mention these again, Zhang Feng word, seems to want to restore the discretion of the original judgment.
"Xie command, the X box may not be loaded." 1 minutes later, Zhang Feng appeared in front of power commander Xie Ting.
Xie Ting could hardly believe his ears. The production process and quality inspection process of the ignition kit are very strict. He has been in the line for more than 10 years, and has never heard of any problems with the cartridge case. The test room also immediately exploded the pot. "Someone asked if I would have made a mistake." Looking back at the scene, Zhang Feng's larynx moved, "to tell you the truth, I wasn't sure at that time." If the
ignition kit has problems, it means that the rocket three stage engine can not start, and the satellite can not orbit accurately. Billions of dollars of investment will be wasted, and research achievements in a few years will be destroyed.
Sheffield immediately called the technical backbone. After weighing accurately, this kit is 4.5 grams lighter than the standard, and this is the weight of the charge. After the box was broken down, it was empty. Zhang Feng eliminated a major safety hazard of the trial task and saved huge economic losses for the country. To this end, he has made the first grade of himself and became the only outstanding achievement of the center.
7 20, before the launch of the rocket, a head office leader heard about Zhang Feng after hearing the matter and praised him for his duty as a space fighter. "The chief also has a close relationship with my soldier!" It was hard for Zhang Feng to hide his excitement.
soon Zhang Feng will be promoted to sergeant three. Such an honor, the center is only one this year. Speaking of the future, the Post-80's biggest expectation is to send more rockets to heaven.
