How to "four seasons like spring"?How to "online"?Reveal the secrets of the Tianyan Experimental Crystone Ask the aerospace technology on the road

On July 24, the first experimental cabin in the construction stage of my country's space station — asked the Tianshi Experimental Cels at the Wenchang Aerospace launcher in Hainan. In the early morning of the 25th, I asked the Tiangan experimental compartment to be connected with the Core and the core compartment combination.

In this flight mission, which aerospace technology is escorted to ask the road of the Tiangan experimental cabin?

Why can I ask the experimental compartment why can the four seasons be like spring? "

When the spacecraft is ordered, there is no protection of the atmosphere. In the case of the sun, the surface temperature can reach more than 100 degrees Celsius. When there is no sunlight, the temperature will drop below minus 100 degrees Celsius.

As the most heaviest and largest single aircraft in my country, in the very cold and hot space environment, if you want to ensure that the various equipment in the cabin is always in a comfortable environment of more than 20 degrees Celsius, it is necessary to rely on the Aerospace Science and Technology Group The "Space Air Conditioning" developed by the Fifth Hospital Space Station asked the Heavenly Experimental Card Thermal Control Team.

The core of "Space Air Conditioning" is the liquid cooling system in all positions. Wang Dewei, the head of the Fifth Hospital of Aerospace Science and Technology Group asks the experimental cabin, introduced that the team developed three sets of liquid cooling systems in order to ask the Tianjin Experimental Cool to ask various equipment or various equipment or various equipment or various equipment or various equipment or various equipment or various equipment or various equipment or various equipment or The heat generated by the test load is collected and radiated to the outer space, which can support the heat dissipation of the test load of the test load above a kilowatrous level. One of the sets of heat dissipation circuits specifically for inspection loads specifically for outdoor test loads.

At the same time, the developers of the Fifth Hospital of Aerospace Science and Technology Group have developed large -sized and efficient interface thermal conductivity, taking into account the dual purpose of overload and thermal conductivity.

In the development of "space and air conditioning", in order to meet the temperature control requirements of some special equipment, many new technologies have debuted, such as "white coats" with more than 90%of the solar reflectances on the cabin equipment, graphene thermal cable technology, etc. Essence

Asked how to "real -time online" the experimental cabin?

Aerospace measurement and control communication refers to the ground station to measure, remote control and data transmission of the spacecraft, remote control and data transmission. It is the only connection between the spacecraft and the ground after lifting off, just like the line of kite. Therefore, aerospace measurement and control communication is also called the "lifeline" of spacecraft.

In this question, the Sky Experimental Cel was lifted off, and China Electric Sciences used more than ten land -based measurement stations, sea -based measured vessels, and Tianchain Zhongjie Satellite to weave a full -coverage measurement and control communication network.

Chai Lin, chief expert of China Electric Power Department, said that my country has established a third -generation "comprehensive chemical measurement and control system", which has the characteristics of "multi -component, deep integration, high reliability".

The third -generation "comprehensive chemical measurement and control system" adopts the design concept and technology of resource reorganization, that is, the various parts of each part reconstruct a variety of equipment forms in a cross -combination. The system forms flexible and diverse. Spend.

According to Chai Lin, the new generation of measurement and control equipment is an integrated system for measurement and control, which has both traditional measurement and control functions and high -speed data transmission functions. Two types of data are integrated and transmitted to save resources.

The integrated device is the same as smartphones. It can support multiple applications in a set of aerospace measurement and control communication devices at the same time. Different signal forms, working modes, and technical systems can be used at the same time or separately.

Asked how to ensure water for the experimental compartment?

For a long time, space urine treatment and water recycling technology are recognized technical problems, and it is also one of the core key technologies for the construction of Chinese space stations.

After the second set of environmental control -preserving urine treatment subsystems developed by the 206 of the Second Hospital of Aerospace Science and Technology Group, after the launch of the skycase was launched, it was put into use after completing the heavens and the core compartment. After the overall plan, the astronauts multiplied by the group. The state of the urine treatment subsystem will be set and the orbit test is performed to confirm whether the functional status and performance indicators of the system are normal. After the test is passed, the system will be regularly cleaned in accordance with the overall plan.

According to the overall plan, after the launch of the experimental compartment and the dream of the dream day, the China Space Station will complete the construction of the orbit, and then the space station will be transferred to the long -term operation stage. At present, the first set of urine treatment subsystems located in the core cabin operates normally in accordance with the rhythm of the rhythm to ensure the normal water use of the astronauts. The collaboration provides clean recycled water for the long -term residence of the Chinese astronauts multiplication.

The first urinary treatment subsystem was launched on April 29, 2021, and the core compartment was launched on the day, and six astronauts in Shenzhou 12 and Shenzhou 13 were successfully guaranteed in the orbit for a long time. At present, the first set of urine treatment subsystem products are normal during operation and stable performance. (Reporter Song Chen, Hu Yan, Wen Jinghua)
