At 14:22 on July 24th, the China Space Station asked the Tiangtian Experimental Class at the Wenchang Aerospace launcher in Hainan.

As the second cabin construction of my country's space station, what new equipment will be brought to the space station? What changes will the work life of astronauts in space?

At 14:22 on July 24th, the Long March 5 Yao Three Load Rockets equipped with the Experimental Class of the Sky and launched the fire on time at the Wenchang Aerospace launcher in my country. Rail, the launch has achieved a complete success. Xinhua News Agency reporter Yang Guanyu

Strong function and equipment: China Space Station welcomes "new residence"

"Ask the Tianjin experimental cabin consisting of three parts: working cabin, air gate and resource cabin. The total length of the cabin is 17.9 meters, 4.2 meters in diameter, and the launch weight is about 23 tons. The largest single aircraft. "Said Liu Gang, deputy chief planner of the Fifth Hospital System of Aerospace Technology Group.

Not only does it have a large body, and asked the Tianjin experimental cabin is a "all -round" player integrating platform functions and load functions.

According to reports, I asked the Tianjie Experimental Cels and the Core Card to back up. The key platform functions were consistent, which can fully cover the work requirements of the space station combination. Essence

"After the two -cabin docking is composed of a combination, the manned environment of the entire space station is uniformly managed and controlled by the sky and the core compartment. Once the sky and the core compartment occur seriously, ask the Tianjin experimental cabin to quickly take over and control the space station." Luo Yabin, chief designer chief designer of the Tiantian Experimental Card Environment Control System.

A more important detail is that asking the Tianjin experimental cabin is equipped with the largest flexible solar wings in China, and the double -wing can reach 55 meters after the development of both wings. The sun wings can track the sun with dual freedom, and the average daily power generation exceeds 430 degrees, which will provide sufficient energy for the operation of the space station.

Qi Tian's experimental cabin is the cabin with the most part -time parts in the space station system. A large number of out -of -the -cabin facilities and equipment can better guarantee the outlet activities and also provide support for more detailed off -class operations.

Outside of the air gates of the Tiantian experimental cabin, there is also a set of 5 meters long robotic arm. This set of 7 -degree of freedom has a small robotic arm, high accuracy, and more exquisite operation. In the future, the arm can also be composed of a 15 -meter -long combination arm with the core cabin large arm, and more out -of -class operations can be performed at the three -cabin combination of the space station.

Time and high difficulty: "Fat Five" performs "muscle gain and weight loss"

As the "carrier line" of the construction project of my country's space station, the Long March 5 series of the Long March 5 series of the Lange Rockets nicknamed the "Fat Five" has previously successfully sent the sky and the core compartment to space.

This time, five B will not only launch the heaviest load in my country so far, but also face the problem of low -temperature pushing agent injection problems and complex predecessor processes. The difficulty can be imagined.

During the ignition phase, the model team optimized the launch process of 10 minutes before the shooting, and the part of the process was the same. A few minutes before the launch, the Rockets have completed the preparations before the launch, and have the ability to ignite the launch, leaving the time for emergencies to make decisions and disposal.

The long five B also applies the take -off time correction technology, so that the rocket's control system can automatically calculate the deviation and adjust the target track. The maximum correction time is 2.5 minutes.

"Even if the Rockets fail to launch completely according to the scheduled window, as long as the window time of 2.5 minutes can be accurately completed through the track and connection of the subsequent track." Lou Liang said.

In order to continuously improve the reliability of the rocket, safe and precisely send the test compartment to the destination, the model team also conducted a targeted "muscle gain and weight loss" on the long five B, and in terms of production technology and other aspects Improve.

As the number of launch increases, scientific researchers have continued to understand the rocket technology status. Earlier, the launch preparation time of the long five B was about 60 days. This task was further optimized to 53 days, laying the foundation for the subsequent improvement of rocket launch efficiency and responding to the normalized launch of high -density.

Large tonnage, semi -autonomous: "kiss of space" has new highlights

After the interview compartment is track, it will be carried out with the core compartment combination -23 tons of Qi Tian experimental compartment and more than 40 tons of core compartment combinations, which will be the two aerospaces in my country. The connection between the meeting is also the first time that the China Space Station has greeted the spacecraft's visit in a state.

Heavy weight, large size, small targets, flexible solar wings are difficult to control ... For a series of tricky problems faced, Song Xiaoguang, deputy director of the GNC sub -system of Aerospace Technology Group, asked for an image. "If you look at the weight, the manned spacecraft is connected to a small sports car with strong controllability; the cargo spacecraft is connected to a small truck; and when you ask the Tianhe Mengtian experimental cabin, it is like a large RV equipped Pass to a small parking space. "

In order to successfully realize the "space kiss", the design team has undergone several rounds of measurement from the initial development of the experimental compartment, and accurately grasp the data parameters of the test compartment, and improve the algorithm to achieve stronger adaptability and correction ability. At the same time, the semi -autonomous meeting docking plan is adopted to achieve stable control in the process of meeting and docking. During the rail, asking the Tianjie Experimental Curring will also achieve a flat transition of 90 degrees, allowing the interface of the interface to the interface in front of the node cabin to the side of the interface, and the side of the node cocktail. The front -oriented interface of the cabin is fully prepared for the visit of the Dream Sky Experimental Cels. This will be the first time in my country to assemble in orbiting, and it will also be the first international exploration of a flat -type converter.

More comfortable and safer: "condition upgrade" in space life

For the rails, the two -cabin docking form a combination, which means that our space home has been upgraded from "one bedroom" to a more spacious "two -bedroom".

Ask the working cabin of the Tiantian Experimental Curring, there are 3 sleep areas and 1 sanitary area. After completing the docking, the space station can support the six astronauts of Shenzhou No. 14 and No. 15 to achieve the "Space Society" and rail rotation in the rails, and hand over in space.

Li Jinlin, director of the overall trial of the Aerospace Countercact, said that on the basis of the heaven and core compartment, I also optimized and upgraded in the aspects of sound absorption, noise reduction, and shock absorption.

Earlier, astronauts could only achieve the cabin through the node compartment in Tianhe's core compartment. The node compartment is the transportation hub of the space station, and the space is small. Each time the astronauts also need to close the cabin door of each docking channel, a large number of preparations.

This time I asked the test compartment with a air gate for a cabin personnel. On the one hand, the space of the air gate and the size of the cabin door is larger than the node compartment. The spacemen are more stretched and calm, and it is also easier to carry a large volume of equipment out of the cabin. On the other hand, when the air gate is out of the cabin, just close a cabin door to operate more conveniently.

In the future, the air gate will become the main outlet passage of astronauts in the space station. Once there is a problem with the air gate, the astronauts can also return from the node compartment as a backup outlet to ensure the safety of the cabin activities.

On the exposed experiment platform outside the air gate, 22 standard load interfaces are also equipped. "The scientific experimental load equipped at the space station can be accurately submitted by the robotic arm to the corresponding load interface position of the load, and no longer needed to leave the cabin to perform manual operations, which not only reduces the work strength and risk of the astronauts, but also can also be possible. Flexible and efficient support for the out -of -class load test. "Zhao Zhenhao, chief designer of the Fifth Hospital of Aerospace Science and Technology Group asked the Temple of Space Technology Test System.
