What are the points of this task?

The reporter learned that, as the first experimental cabin of China Space Station, it is also an important part of the National Space Lab. It will carry out a number of life science experiments such as plants, animals, microbial cells, and provide a larger platform for long -term spatial scientific research in my country to carry out a series of long -term spatial scientific research.

China Space Station is about to usher in the first experimental cabin

This is the first time that the China Space Station has greeted the spacecraft with a spaceman, and it is also the first experimental cabin ushered in by China Space Station.

Wang Xiang, chief commander of China Manned Aerospace Engineering Space Station system, previously introduced to reporters that the basic configuration of the China Space Station has three cabins, including the "Tianhe" core compartment, "Ask the Tian" experimental cabin and the "Dream Tian" experimental cabin. The overall space station is T -shaped configuration, and the core compartment is in the middle, and the two experimental cabins are connected to both sides.

On April 29, 2021, with the successful launch of the "Tianhe" core compartment, the China Space Station carrying hundreds of millions of people's dreams was fully launched at rail assembly construction. "Heaven Palace" is no longer the myth of the ancients's universal universe. Since Shenzhou 14th manned spacecraft successfully sent Chen Dong, Liu Yang, and Cai Xuzhe to the "Tianhe" core compartment on the morning of June 5 this year, and the Shenzhou 14th flight multiplication group has been on the track. It has been staying for more than a month.

According to the plan, after the launch of the "Ask Sky" experimental cabin, it will be connected with the Chinese Space Station. The "Ask Sky" experimental cabin will complete the formation of a "one" font combination with the core compartment of "Tianhe".

The "Ask Sky" experimental cabin weighs more than 23 tons and has a length of 17.9 meters. It is the largest space station single cabin section in my country at this stage. The 23 -ton "Ask Sky" experimental cabin and more than 40 tons of space station combinations will be the connection between the two spacecraft with the largest tonnage in my country. It is also the first time that my country's space station has met and docking in a state.

You can conduct space life science research. In the future

The "Ask Heaven" experimental cabin consists of a working cabin, the air gate, and the three -cabin of the resource cabin. Its main task is to support the application of the sealing capsule and the out -of -class test. At the same time, it supports spacemen's outlet activities and configure small robotic arm.

Scientific experiments in space are the main mission of China Space Station. China space station can deploy 25 scientific experimental cabinets. Each experimental cabinet is a small space laboratory, which can support the development of spatial scientific experiments with cross -disciplinary or multi -disciplinary cross -section, which has reached the international advanced level as a whole. The experimental cabinet in the "Ask Sky" experimental cabin is more than the core compartment of "Tianhe". The working cabin is equipped with 8 experimental cabinets. These cabinets are one of the most important loads of the "Ask Heaven" experimental cabin. In addition, 4 scientific experimental cabinets including life ecological experimental cabinets and biotechnology experimental cabinets are deployed in the experimental cabin. It is mainly for spatial life science research and supports astronauts in space in space. Research on response mechanisms such as growth, development, genetic, aging. The addition of the "Ask Sky" experimental cabin will greatly enhance the function of China Space Station as the function of the national space laboratory.

The reporter learned that after the "Ask Heaven" experimental cabin was in place, Shenzhou No. 14 multiplied group will bring a new round of space lectures in this "new classroom".

In addition, the "Question Tian" experimental cabin is equipped with the same aerospace staff living facilities as the core compartment. In the future, it can be accepted with the life of the 6 astronauts during the period of two manned spacecraft rotation. If the "Tianhe" core compartment fails, the "Ask the Tian" experimental cabin can control the space station as a backup cabin section.

It is reported that my country will also launch a "Dream Sky" experimental cabin in October this year, equipped with multi -disciplinary experimental cabinets such as fluid physics, material science, combustion science, basic physics, and aerospace technology tests.

The launch time is "5 2", which is the result of scientific calculations

14:22:22 Beijing time, "Ask the Sky" experimental compartment launch.

"At 2 pm, 22 minutes, 22 seconds, there are 5 2. Is this coincidental? Or did it be intentionally selected?" When the launch time of the "Ask Heaven" experimental cabin was announced, the netizens were curious to ask. The answer is: the launch time window is scientifically calculated, 5 2, purely coincidental.

Pang Zhihao, the chief scientific communication expert of the National Space Detection Technology, said that the launch of the spacecraft has a best window period, which is determined by multiple factors. "It is necessary to establish a mathematical model, enter relevant data, and then carefully calculate according to the conditions of the track conditions of the celestial body, the working conditions requirements of the spacecraft, the working conditions requirements of the spacecraft, and the ground tracking and control communication, meteorological requirements, and meteorological requirements."

Pang Zhihao explained that the best launch window of the "Ask the Sky" experimental cabin is the most important thing to consider it to meet with the core compartment of the "Tianhe". "The ground launch, the right time node should be selected. When the most time -saving and saving fuel, complete the 'space kiss'." Specifically, when the ground launch, you must fully consider the situation of the ground storms and lightning. On the same day, Hainan Wenchang's ground wind was 3 meters/s, and the weather was fine. Don't worry about the lightning lightning. At the same time, the waves are not high, which meets the requirements of the sea waves in the place where the measurement ship is located.

Shaanxi Aerospace Technology provides a full range of liquid power, helping to push the launch of the test compartment

The Sixth Hospital of Aerospace Technology Group provides all rocket power systems for the core -level power composed of 50 -ton hydroxide engines and 8 120 -ton liquid oxygen and oil engines for this launch of rockets. The "Ask Sky" experimental cabin provides 36 -rail control engines and other power system supporting products for rail control and gesture control.

With the success of this launching task, China's first space station will usher in the longest single manned spacecraft in the longest space station in the rail space station. In the 8 tasks that have been completed in the space station, all the motivation of the Sixth Academy provides perfect performance.

Drimming strength, sending the maximum spacecraft to space

Compared with the core compartment of "Tianhe", the "Ask Sky" experimental cabin so far, the largest and longest single aerospace in the space is 1.3 meters older than the "Tianhe" core compartment, full There are 6 floors of the height. As an important part of China's first space station "Tiangong", the "Ask Heaven" experimental cabin is mainly used for spatial life science research. It will effectively promote major cutting -edge scientific and technological breakthroughs such as life ecology, biotechnology and gravity science. Essence

On April 29, 2021, the Long March 5 Yao II Load Rocket successfully sent the core compartment of the space station "Tianhe" into the scheduled track. China Space Station was fully launched at the rail assembly and construction. After the baptism and test of two major tasks, this time the Long March 5 B will send the second cabin of my country's space station- "Ask the Sky" experimental compartment into space.

11 The members of the test team combined with the seven -time execution task and the completion of the test content to carry out the parameter packaging re -identification, give full play to the advantages of the front and back linkage of the liquid oxygen and oil engine development team, establish a parameter interpretation package, the data of the data horizontal and vertical comparison has the contrast in accordance with. At the same time, a topic analysis of strong blowing adaptability was carried out, and special analysis was carried out on the discussion plan of the minimum launch condition parameters and delayed launch reverse process plans, which provided a solid guarantee for the zero window launch.

11 (Beijing) test team members have completed the inspection, unit testing, sub -system testing, general inspection testing and cooperation on the day of launching the test equipment. In the process, the test data of each link is needed to analyze and read, and confirm the state of some key operations involved in the engine. It fully achieved the selection of product excellence, and it was cautious to read it, which further enhanced the reliability of hydroxide engines.

801 undertakes the development of the "Ask Sky" experimental compartment. The system's basic configuration includes 4 490N rail transformation engines, 24 150N and 8 120N position control engines, 4 400L storage boxes, 4 40L composite Material high -voltage gas cylinders, system control and parameter collection electronic single machines, promoting system pipelines and thermal control systems. At the same time, in order to meet the requirements of the "Ask Sky" experimental cabin in 15 years in the rail life, the "Ask Sky" experimental cabin adopts a cross -supply plan and the new dual -sealing structure in promoting the system gas and liquid road pipelines. Identify the risk, conduct experiments, and verify the long -term safety of the storage storage storage storage promotion agent to ensure that the canal production of the rail transformer engine is reliable. Thousands of practice, success is not happening overnight

11 Director Li Miaoting deeply felt that as a member of the experimental team, fully ensuring the quality of the engine is the prerequisite for the successful launch. Under the joint efforts of everyone, each position and each player of the test team performed their duties. To ensure that each link, every operation, and interpretation of each interpretation must be successful, all correct, and "three careful" and "one guarantee" in order to ensure the construction of each major flight launch mission at the space station. The process is perfect, and the result is complete.

According to He Kun, deputy chief president of 11 (Beijing) model, this launch requires accurately controlling the launch time, that is, "zero window launch", in order to seize the best connection time with the core compartment of "Tianhe". In addition, "first -level precision". At present, as the only power product that can directly and precisely track after the ground takes off, the large thrust hydrogen and oxygen engine will accurately control the changes in the thrust and accurately send the three cabins of the space station to the scheduled track. Forecast and consistency analysis put forward higher requirements.

"During the preparation of the launch of the experimental compartment launch of the" Ask Sky ", all members of the experimental team strictly implemented the requirements of high -altitude injection, improved the design of the system, reducing the risk point of leakage of the injection process, and organized multiple rounds of job drills and deductibles. , Strictly implement the control measures for the additional injection process, strengthen operation supervision and inspection confirmation, and use the standard of "three or two standards' (no quality accidents, no safety accidents, no leakage of a propeller, and complete the additional injection on time). The "Ask Sky" experimental compartment pushing agent is successfully completed. "Gu Shuaihua, the Minister of the System Division of 801, said confidently.

President terminals, in order to ask the sky experimental cabin to set up "Space Sky Road"

After the successful launch of the test cabin was launched after entering space, the relatives developed by Xi'an Branch were turned on as soon as possible. Subsequently, the "space handshake" of the relay terminal and the sky chain recreation satellite established a star link, thereby setting up the "Space Sky Road" from the questioning compartment to the relay satellite to the ground.

The ground measurement and control personnel will focus on the heavenly base measurement control system, and control the implementation of the testing of the experimental compartment in the orbit. The remote control method of the ground test is remotely controlled, and the posture of the spacecraft will be controlled, and the communication is established with the ground. Remote driving.

After entering the predetermined track, the test cabin will meet with the space station that has been running in the space station and the core compartment in space.

After the completion of the sky -based test control communication system established by the truncer terminal, the ground -to -the -ground experimental compartment and space station measurement and control coverage rate was increased to nearly 100%, and ensuring that the Tiangtian experimental cabin maintains real -time communication with the ground.

Antenna network, the signal forwarder of China Unicom Tiandi

The antenna network developed by Xi'an Branch in order to ask the Tianjin Experimental Cels provided a special measurement and communication signal transmission channel, and established a high -speed and unimpeded command and feedback information channel in order to ask the Tianjin experimental compartment and the ground to ensure that the task was completed smoothly.

The antenna network is a key product that connects to the response machine and antenna in the measurement and control and communication sub -system, that is, a small signal forwarder on the spacecraft. When the Tianyan experimental compartment receives the communication signal or measurement and control instruction signal on the ground, the antenna network will classify it and transmit it to the answer machine. Conversely, the various types of signals from different channels of the responding machine will also be sent to the ground antenna, and the ground will be sent to the ground through the antenna.

Ask the Tianji test control will be carried out on the orbit flight control. The antenna network will mainly complete the upload and release of the experimental compartment test control instruction signal. In the track task, the operation instructions need to be ensured in real time and accuracy, and the high reliability of antenna network products will become one of the important guarantees of the task.

"Smart Brain" of the experimental cabin

Xi'an Branch also undertakes the development task of the instrumental computer application software in the test compartment. When the computer was turned on, the computer application software of the experimental cockpiece was officially started to operate independently. The "smart brain" of the instrumental application software as an experimental compartment instrument is the function of the data processing center system of the experimental meter instrument, which is responsible for the internal and external data information processing of the experimental meter and the lighting system.

Qi Tian's experimental cabin has a complicated computer application software, which belongs to the multi -task and real -time requirements of operating systems with high real -time requirements. Zhang Chiping, the person in charge of the computer application software of Xi'an Branch, said: "Compared with the previous manned aerospace engineering tasks, the computer application software of this instrument has increased the space station on the basis of inheriting the space station of the space station. Data interaction of Tianhe's core compartment. In this way, the data volume will increase greatly, and our team will solve this problem successfully. "The construction task of China space station is underway, and it is also underway. Step by step to us the new development map. Xi'an Branch has continued to play a role in the compatriots, antenna networks, and instrumental computer application software developed by the aircraft station, which continues to contribute to the stable operation of my country's space station.
