Successful launch!"China Strongest" sends "China's heaviest" to space

At 14 o'clock on July 24th, my country used the launch carrier rocket with the strongest launch capacity of my country's current near -ground rails in Wenchang Aerospace launched in Hainan -Long March 5 B. So far, the largest load of weight -asked the sky experimental compartment to the scheduled orbit. The key battle of China Space Station has achieved a complete success!

According to a reporter from the Global Times, as another main cabin section of the China Space Station, I asked the Tiangan experimental compartment consisting of working cabin, air gate and resource cabin. The total length of the experimental compartment is 17.9 meters, 4.2 meters in diameter, and the launch weight is 23 tons. Its "block head" and "weight" are equivalent to a carriage of the Beijing Metro Line 13 train. Asked about the heavenly experimental cabin, it is also the heaviest single -cabin active aircraft in the world in the world.

The large volume is also very powerful in function. Ask the Tianjin experimental compartment and the China Space Station Tianhe core compartment backup, integrating platform functions and test load functions. Not only is it loaded with 8 experimental cabinets and 22 cabins, which is equivalent to moving a large scientific laboratory to space. There are 3 sleep areas and 1 sanitary zone in the cabin. After ushered in the test cabin, the number of "beds" of China space station reached 6. This also created conditions for the subsequent Shenzhou 15 manned spacecraft, the two multiplication groups of Shenzhou 14, Shenzhou No. 15, and six astronauts, and the space station "Manchu" operation created conditions.

What is the difference between the newly added "bed" in the experimental cabin and the "bed" of the previous core compartment? In an interview with the Global Times reporter, Liang Xiaofeng, the overall director of the Aerospace Science and Technology Group, "revealed" that from a functional perspective, the two sleep areas of the core compartment and the experimental cabin were the same, but in the core, but in the experimental cabin, it was the same The specific design will be slightly different. For example, each "bed" of the experimental cabin is equipped with a portholes. This means that the sleeping area of ​​the experimental cabin is "Starry House".

In the questioning compartment of the sky, there is also the only cabin that looks square -out in the space station system -out of the cabin gas gate. The "Foreign Internal Circle" cabin is also the "locker room" when the spacemen launch a cabin event. It is understood that the space gates on the cabin on the test cabin are even greater. When the astronauts are preparing for the cabin and returning outside the cabin, they can be more stretched, calm, and carrying a larger equipment out of the cabin. The cabin can work. The cabin can work. The ability of foreign work is greatly improved. This outlet air gate will also become the main outlet channel for the entire space station system in the future.

In addition, I asked a set of 5 -meter -long robotic arm outside the air gate of the Tiangan experimental cabin. This set of 7 -degree of freedom is small and highly accurate, which is convenient for grasping small and medium -sized equipment, and the operation is higher. What is quite sci -fi is that this small robotic arm can also be connected to a 15 -meter -long combined arm with the large robotic arm on the core cabin to expand the exterior operation. At that time, this combined arm can crawl between the three cabins of the Chinese Space Station's combination of Heaven, Qi Tian, ​​and Mengtian, like a "mech warrior" walking in space.

It is worth mentioning that the launch task is also the first time that the long -five rockets perform zero -window launch tasks. For this large -scale low -temperature rocket in my country, it is difficult to perform this kind of mission -to -second launch task.

Liu Bing, the overall deputy chief designer of the long five -B rocket, introduced that the launching task of the zero window requires that the long B Rockets must be launched in seconds at the prescribed time, otherwise they will not be delivered to the designated position of the test compartment, and then they will not be delivered to the designated position, and then they will not be delivered. It is necessary to cost a huge price to adjust the track and even lead to the termination of the launch. "If this happens, you need to wait for the next launch window to re -organize the launch, which seriously affects the task cycle." Liu Bing said.

In response to the challenge of the "zero window" of this launch task, Hainan Wenchang launched the preparation process of 10 minutes before the launch. Zhong Wen'an, chief engineer of Xichang Satellite Launch Center, introduced that the launch system has carefully repaired the key plans before the launch of emergency shutdown, delay launch, and pushing agent leakage, and refine the implementation of more than 1,000 plans for positions, system levels, and job levels. , To support scientific decisions before launch, to achieve timely launch, safe launch, and successful launch.

In order to ensure that everything is lost, the five -B rocket test team innovatively designed a "take -off time correction technology". Lou Liang, deputy chief president of the Aerospace Science and Technology Group President No. 5, said that this technology can automatically calculate the deviation of the rocket's control system and adjust the target track. Within 2 minutes and 30 seconds, the Rockets can accurately complete the orbit and meet with the subsequent rail correction. This is equivalent to expanding the launch window from "0" to "2 minutes and 30 seconds" with technological innovation.

It is understood that this year's long -five B Rockets will also undertake the launch task of the Mengtian experimental cabin, helping the three cabins of China Space Station to form a "T" based on the basic configuration, and complete the construction of China Space Station in the rail. And next year, the long five -B Rockets will also undertake my country's first large -scale space patrol telescope launch task. At that time, China Space Station will be able to carry out more deep space detection and cutting -edge scientific research.
