The 70th anniversary of the Southern Airlines received blessings from space!

"Capsule No. 1" satellite intelligent management unit transmitted cabin in the cabin

On August 21, the teachers and students of Nanjing University of Aeronautics and Astronautics received a blessing from space from space. The school's small satellite space control laboratory, Professor Kang Guohua team, and developed the intelligent management unit "Number No. 1" developed in the satellite cabin. , I added a strong stroke to the school again.

From "Plant Capsules" to "Capsule No. 1", all -round innovation and upgrading

At 12:11 on August 9 this year, the "Number No. 1" followed the "East China Sea No. 1" satellite on the Star River Power Aerospace Company Gu Shenxing I (Away 3) · Xingguang Yicai Lae Rockets, and successfully entered the scheduled track. On August 11, when the "East China Sea One" satellite passed over the Shanghai measurement and control station, as the ground instruction was injected, the "Capsule No. 1" successfully turned on and passed the remote test data smoothly.

The reporter learned that the intelligent management unit of the "Capsule No. 1" space environment uses the new satellite intelligent technologies independently developed by China Southern Airlines. It is an important part of the "East China Sea One" satellite platform. The collection and intelligent management of environmental data such as air pressure can effectively improve the fineness and intelligence of satellite platform environmental management.

Under the guidance of Professor Kang Guohua, the team consisting of a team consisting of the students of the Academy of Aerospace and the School of Automation participated in the creative launch, principles design, and engineering implementation. The design and setting of the load.

"You can imagine it as a cube -like cubic block. Although it is not large, the sparrows are small and the five internal organs are all." Essence According to reports, cubic stars are a cube of small satellites that are proposed as early as 1999.

The predecessor of "Bianqian No. 1" was the creativity of the 'plant capsule' proposed by Kang Guohua. On April 24, 2021, the China Aerospace Conference was held in Nanjing. At the Cube Star Strip Forum, the first World University Student Cube Star Challenge was officially official Starting, the team has made a high breakthrough and innovative work with a very breakthrough and innovative work, and has won the special prize of the China Finals (only 3 nationwide), and also won the international finals Field coupons.

"Sending research results into space" is the goal that Kang Guohua and team members have long been determined. The "Capsule No. 1" that inherits the key technology of "plant capsule cubic star" came into being.

All the way to overcome all kinds of challenges and create a unique space "Sunshine Room"

"The‘ Number 1 ’is all glass on all sides of the wall. For example, it’ s like the sun room in the space. ”Teacher Kang Guohua said.

To ensure that the external structure of the "Sunshine House" is stable and reliable, it is a huge challenge for the entire team. "We open four windows on a small cubic structure with a length and height of only 10 cm. This is the first time to apply such a large -scale transparent glass component in the cubic star architecture." Hua Yin, who is responsible for the design of the external structure, Miao introduced that in the face of the strong shock of the rocket during the launch, and the rapid cold and hot crossing in space, the glass components were easily broken. Once a crack occurs, the gas tightness of the sun room will be destroyed. Maintaining will also cause hidden safety hazards.

The installation, protection and sealing of glass components on the spacecraft have always been difficult for engineering design. The intense vibration of the launch phase and frequent hot and hot changes during the track period have high requirements for the glass and its connection structure. "In order to achieve the concept, in design, we wrap each edge of the glass with a special shape of the rubber layer to play a dual role of sealing and protection."

In the mechanical vibration test, once the glass cracks, everything you do must be returned. "When the vibration of the three directions is over, the appearance is intact, and everyone will be relieved." Responsible for the external structure. Huayin Miao, a 20 -level doctoral student designed. Members participating in the "Capsule No. 1" project include China Southern Airlines undergraduate, master and doctoral students, with 5 core members. "In order to complete this project, every member of the research team helps us." Whether it is a good result in the competition, or the happy results of the project's final successful lifting, the team of mutual assistance and unity and love behind Master.
