Chinese aerospace story: task restart must leak 400 tons of rocket fuel than a hundred times dangerous to add

Dare to defeat all difficulties and obstacles, and be brave to climb the peak of aerospace technology.

At the History Exhibition Hall of the Xichang Satellite Launch Center, there is a set of slightly yellow injection protective clothing. In the battle of Beidou's network in 2020, the operator wearing the work suit successfully completed the full -arrow fuel leakage and injection work, creating a great miracle in the history of Chinese aerospace.

"The hinterland of Liangshan, the cradle of aerospace, we wrote down the volunteers of life here ..."

This "Song of the Injusca Team" is written in the most dangerous injection post, the loyalty and responsibility of Xichang Aerospace people. The main fuel of the Rockets -hydrogen and oxygen mixture, as long as the energy of 0.019 mm, is probably the energy generated by a grain of rice from one meter at a high place, which is enough It is strongly corrosive, and the yellow smoke rolled in the rolling yellow smoke after being volatile.

Zhou Xizhen, an injecting position, is a member of this "knife dancer".

Zhou Xizhen is a party member of 9 years. He has been in the post for 12 years.

On the evening of June 15, 2020, the Long March III Blind Rockets, which launched the last global networking satellite of Beidou No. 3, found product technical problems during the test before the shooting. The launch task was delayed.

The technical problems were quickly detected, but to restart the launch task, it must first leak the nearly 400 tons of rockets that have been injected first.

Fuel injection is extremely dangerous. The fuel was leaked, which is 100 times more dangerous.

At the critical moment, more than half of the Xichang Satellite Launch Center of the party member's injection team carried out the heavy responsibility of leaking rockets, and the party members also took the initiative to form an assault team.

The team's party branch repeatedly studied the technical difficulties of the pushing agent for 3 consecutive days, analyzed the status of nearly 500 valves, 1,600 meters pipelines and other equipment and facilities, organized 8 times to leak the drill, refined the leakage plan to the minute level, accurately to each one Actions, every order order, strive to minimize risks.

At 8 o'clock on June 19th, the tackling battle of the oxidant fourth oxide nitrogen was first launched.

The first upper -end operation was Zhou Xizhen. He and his teammate Jiang Yifan played the "sharp knife" -the first group of the missing tasks, responsible for the first ball valve of the first and second -level injection of the Rockets, and the first -level and second -level injection pipeline connection. On the 2nd, 3rd and 6th layers of the tower.

"I am a party member and the backbone of the business. I do n’t worry about opening the first ball valve, I’ m not relieved. ”Zhou Xizhen said.

"Start Ⅱ and IV booster oxidatives leaked!"

After hearing the commander's scheduling order, Zhou Xizhen held the additional valve control wrench tightly with both hands, so that the maximum strength stabilized the wrench and slowly rotated 30 degrees clockwise, and then leaned over with his ears to listen to the flow of oxidant quietly with the pipeline. the sound of. After more than 40 minutes, after the launch site confirmed that the oxidation agent of the II and IV booster was leaked, Zhou Xizhen and his teammates immediately began to implement the Ⅰ and III booster oxidant. The party members' assault team successfully completed the leakage of oxidants.

In fact, from the "Australian Star Defense War" in 1992, more than 400 tons of rocket pushing agents were successfully leaked, and in 1997, the "Fengyun No. 2 Star" task was successfully organized and the low -temperature promotion agent was leaked and re -injected. The injection unit has been ordered to be urgently rescued before the rocket launch.

On June 23, with the roar of the roar, the Long March 3 B Rockets that were launching a week were postponed to spray the flames of the bears, holding the last global network satellite of Beidou 3 to fly to space. At this point, the Xichang Satellite Launch Center used 44 Beidou launch to make 100 % success, and gave a perfect answer to the motherland and the people.

Each party member becomes a bright banner, and each branch becomes a fighting fortress with a high party flag. Behind the miracle of "Backwater Battle" is the role of the party branch's combat fortress and the role of the pioneer of party members, which provides a strong guarantee for the launch of the space launch and successful success.
