What are the points of the first experimental cabin of China Space Station?

In the midsummer Wenchang in Hainan, the breeze blows the coconut forest. At 14:22 on July 24th, the Long March 5 Yao Three Load Rockets equipped with the Tiantian Experimental Cels was launched at the Wenchang Aerospace launcher in my country. Ask the Tianjin experimental compartment and the Rockets to be separated and entered the scheduled track, and the launch was successful.

In the follow -up, the questioning compartment of the sky will meet with the spatial station combination according to the predetermined procedure.

Qi Tian's experimental compartment is 17.9 meters in length and weighs more than 23 tons. It is the largest space station single cabin section in my country at this stage. To successfully launch this "big block", we must use the new -generation carrier rocket with the largest near -land carrier capacity in my country, the Long March 5 carrier rocket.

Qi Tian's experimental cabin is the first experimental cabin of China Space Station and an important part of the National Space Lab. This task is the first time that China Space Station welcomes spacecraft visits in a state. Recently, the Shenzhou 14th astronauts multiplied by the rails and conducted a hand -controlling meeting backup plan training. The space station combination has also been "in place", and has the conditions to meet with the test compartment of the question.

"Ask the sky" experimental cabin a few highlights

China Space Station ushered in a new cabin -asked the sky experimental cabin. This cabin section is the heaviest load launched in my country so far.

Qi Tian's experimental cabin was launched by the Long March 5 Yao San Load Rockets. Previously, on July 18, Qi Tian's experimental compartment and Long March 5 Yao San Load Rocket Combination had been transferred to the launch area.

For the first time in the space station, someone is in a state to welcome the spacecraft

This launch is the third launch after the Chinese Space Station entered the construction stage. It is also the first time that at this stage to welcome the spacecraft visits in a state.

The overall configuration of the Chinese Space Station is 3 cabins, including Tianhe Core Card, Wentian Experimental Card and Mengtian Experimental Cels. The overall T -shaped structure.

According to Yang Hong, chief designer of the Fifth Hospital Space Station of the Aerospace Science and Technology Group, the overall structure of the China Space Station is 3 cabins, including Tianhe Core Card, Wentian Experimental Card, and Dream Tianyan Experimental Class. Among them, Tianhe's core cabin was successfully launched in April 2021.

After the launch of the experimental compartment, it will be connected with the China Space Station. This is also the first time that the space station will welcome the spacecraft to visit the spacecraft for the time. The surging news learned from the Fifth Academy of Aerospace Science and Technology of the Total Experimental Class. Asked that the test compartment will be connected with the front direction with the heaven and the core compartment, and the "one" type configuration will be completed.

On July 17, the Tianzhou -3 freight ship completed all the established tasks and evacuated the space station combination on the morning of the 17th. The docking port of Tianzhou III's withdrawal before evacuating is the front -oriented interface of the core compartment of the space station. This is also the interface to be connected after the launch of the experimental compartment of the Tianzhou. The physical evacuation was evacuated, and the interface greeted the interface to welcome the interview compartment.

The 23 -ton questioning compartment and a space station combination of more than 40 tons will be the connection between the two aerospaces in my country at the current two largest tonnage. It is also the first time that my country's space station has met and dock in a state. With such a large scene, the docking agency of "hundreds of battles" can still be familiar with it.

The largest single spacecraft in China enters space

Ask the sky experiment.

It is understood that the total length of the test compartment axis is 17.9 meters, the maximum diameter of the cabin is 4.2 meters, and the launch quality is 23 tons. Compared with the working cabin, the air gate, and the resource cabin. Heavier, larger, stronger power supply capacity and gigabit information transmission capacity, which is the largest single spacecraft launched in China so far.

Asked the experimental cabin configured the living facilities of the same spacer as the core compartment. In the future, you can accept the life of 6 astronauts during the rotation of two manned spacecraft in the future. It can be controlled as a backup cabin segment.

It is reported that after we ushered in the test cabin, the astronauts will enter the cabin to start the life maintenance system, complete the assembly of the scientific experimental cabinet, and conduct cross -scientific experiments at the same time. As the main base of space -time life science research in the space station in the future, the working cabin of the Tiangan experimental cabin is also more spacious. A number of scientific experimental cabinets are configured in the cabin to promote our country's life ecology, biotechnology, and gravity science. Related research in the field of science and technology.

In addition, the new space lectures will also be launched in the experimental compartment, and astronauts will also choose to take the first time the outlet and outlets of the Tianshi experimental compartment. Earlier, the Shenzhou 14th Aerospace Worker's multiplier has completed the inspection test of off -cabin. According to the plan, during the track, they will complete 2 to 3 out -of -the cabin activities from the outlet of the Tianshi Experiment.

The Shenzhou 14 manned spacecraft equipped with three astronauts was successfully launched on June 5 last month. It adopted an autonomous and fast meeting docking mode. The core cabin radial port, the entire docking process lasted about 7 hours. At 20:50 on June 5th, astronauts Chen Dong, Liu Yang, and Cai Xuzhe all entered the core compartment in turn. On June 6, the three astronauts successfully entered Tianzhou 4 freight ships at 12:19.

The first zero window of the rocket for the long five B Rockets launched

The launching task is the Long March 5 -Lane Rocket (hereinafter referred to as the long five -B rocket). As the new -generation carrier rocket with the largest near -ground rail loading capacity in my country, the long five -B rocket has a 20.5 -meter largest domestic streaming cover, and the near -ground rail carrying capacity reaches 25 tons. The long five -B rocket has a 20.5 -meter largest domestic streaming cover, with a near -ground orbital carrier capacity of 25 tons.

The long five -B rocket is the first -class semi -type carrier rocket developed on the basis of long rockets. As a member of the "Fat Five" family, it was successful on May 5, 2020, and sent the new generation of manned spacecraft test ships and flexible inflatable cargo return compartment to space. On April 29, 2021, the long five -B rocket successfully launched the sky and the core cabin, which launched the start battle built by the space station.

According to the China Manned Aerospace Engineering Office, 6 flight missions will be implemented this year to complete the construction of my country's space station in orbit. Among them, the long five -B Rockets launched the interconnection with the sky and the core compartment in July. In October, the Mengtian experimental compartment was connected with the sky and the core compartment to complete the construction of the Chinese space station in the rail.

The reporter learned from the Aerospace Science and Technology Group of the Five B Rockets in the total of the total development of the Five B Rockets that in this task, the long -five B Rockets implemented a zero window launch. This is also the first time that the long five -series rockets have performed zero window launch tasks.

"Zero Window" refers to the launch window with zero launch range, that is, the rocket requires that the rocket must not ignore the air in seconds.

Liu Bing, the overall deputy director of the Rockets Dean Five B Rockets, introduced: "Asked the Tiangan Experimental Curring needs to be connected quickly with the space station sky and the core compartment. In position, it takes a huge cost to adjust the track; even leads to the termination of the launch, then you need to wait for the next launch window to re -organize the launch, which seriously affects the task cycle.
