Chapter 2118 East Third B


The next morning, Li Laoer, Li Lao San and Li Weigang also came to the institute. There were also several old soldiers with strong academic flavor but in military uniforms and outrageously high ranks.

According to Li Weigang's introduction, these are all old experts and leaders of the Science and Technology Commission.

This unit is a bit exaggerated. The Science and Technology Commission is now extremely powerful and will not be slightly dispersed until next year's institutional reform.

But no matter now or after the institutional reform, formulating industrial and technical policies and development plans for the nuclear, aerospace, aviation, shipbuilding and weapons industries, implementing industry management, and guiding the industry management of military electronics are all one of its functions.

There is another function, which is the centralized management of the Institute of Engineering Physics, which is the Ninth Institute.

The Institute of Applied Physics and Computational Mathematics is an institute of the Ninth Academy. In other words, it is separated from these old leaders and belongs to subordinates.

Zhou Zhi finally understood why he was brought here to talk about things, and it was all right! "Xiaomiao is still an American?" The old expert looked at Zhou Zhi and Mai Xiaomiao with a kind look. An old expert asked, "Who are there anyone there?"

"And his parents." Mai Xiaomiao said. "That's not easy. Give up the generous life to help us develop disciplines."

"Actually, I live not as good as here." Mai Xiaomiao glanced at Zhou Zhi: "There are many people taking care of me here. I live happily here. At least it's not like two sandwiches to live like a day."

"Hehe, that's good. We are still afraid that you are not used to living a life, so if you want to tell you what you have, just ask." An old man was amused by Mai Xiaomiao's straightforward words: "Our Chinese food is still good. When I was studying abroad, I thought the most about the miscellaneous noodles from my hometown!"

"Yes, after eating the Kung Pao chicken made for me by the elbow, I realized that the Kung Pao chicken abroad is a lie!" Mai Xiaomiao condemned angrily.

"Hahahaha..." Everyone laughed, and an old man asked, "This is the elbow for you to be the elbow of Kung Pao Chicken Ding? Is he taking care of your life very happily?"

Mai Xiaomiao not only was not ashamed, but seemed a little proud, showing off: "Well, elbows are the best for me!"

Everyone was even more happy now, but they no longer laughed loudly like before, as if they were afraid that the laughter was too exaggerated and made the children feel embarrassed to stop each other. "The elbow is also good." Qin Haifeng praised: "Not only has the information technology engineering management textbooks been published, but it is also used for practice. In combination with the foreign ISO quality certification system, we have helped several of our units develop process quality control systems."

"Yes, the last launch was able to send Aoxing to a given orbit in a despair state like the Basin explosion. This is the huge role played by this process quality control system and information system," Li Weigang also said: "It also gives us great confidence in the existing engineering quality management. Now this system has been fully laid out on the base. Actively promoting to the brother units. "

"Okay." An old man nodded: "Let's talk about the satellite contract first, then listen to Xiao Miao talk about the computing power matrix and nonlinear model, then listen to the comrades from the Shipbuilding Institute to introduce the cavitation simulation, and finally let Elbow introduce us to the quality management system and process quality control. How about it? "

"If there is not enough time, it is okay to find time to discuss our affairs." Li Laoer was very obedient, and he saw that the experts were temporarily interested in Zhou Zhi's process quality management system, which was an unplanned arrangement, and he was afraid that they would not have enough time.

"No, no, no, your affairs are also very important." An old man waved his hand quickly.

Another old man smiled and said, "It should be said that it is more important. Without you, we will lose money and gain publicity!"

Seeing this situation, Zhou Zhi knew that Li Laoer had actually had a close conversation with these people. Today is more of a conversation that further connects the relationship. The main thing is to hype the quality of his own satellite and the reliability of rocket launches. Just seeing these people coming to give themselves "firm confidence", Zhou Zhi knew that the country was bound to win.

If it is a normal business behavior, it is time to grasp the other party's mentality and price cuts.

However, Zhou Zhi can't do this, because the price has been given cheap enough, and the cooperation between the two parties is very harmonious. The things Zhou Zhi gave are not young or young, but the four-leaf clover group actually has a lot of rewards, so there is no need to be careful about it.

However, the introduction of the East San B satellite surprised Zhou Zhi at its superior design performance.

This star has reached the most advanced level of similar medium-capacity satellites in the world.

There are 24 C-band repeaters on the satellite, of which 6 are medium-power repeaters; the other 18 are low-power repeaters. During ground shadowing, all transponders can work. The output power of the satellite's end-of-life period is ≥1700W: the allowable payload mass of the satellite reaches 170kg.

Yes, it also has the concept of payload, because it is actually not just a satellite, to be precise, it should be called a satellite platform.

In other words, the East Third One started with the function of a "large cabinet", which has great adaptability and can be used for a variety of satellites with different payloads within a certain weight and power consumption range.

The later designers can become satellites if they install equipment in this cabinet - they can transform it into lunar exploration vehicles, network navigation satellites, military remote sensing satellites, etc., which can shorten the development cycle and improve cost-effectiveness.

It also creates many design firsts.

For example, it is China's first geostationary orbit satellite that leaps from spin-stable to three-axis stable.

In the past, satellites had a rotating attitude in space. To make the satellite always work, three working faces needed to be designed so that the satellites always face the earth during the rotation.

But three sets of equipment are required for three working faces, and at least three sets of facilities must be designed, which will undoubtedly increase the load and power consumption of the satellite.

After achieving three-axis stability, the position errors between the east and north and south of the satellite can be ±0.1°, and the pitch and rolling errors of the antenna are ±0.15°. Therefore, it is enough to design one working surface. The platform itself can ensure that this working surface always works at the earth with extremely high longitude. In addition to ensuring operational stability, it also reduces power consumption, and the saved load and space are installed, which can improve the performance of the satellite.

In addition, there are many innovative technologies, such as the design concept of public platforms; the overall configuration design technology of modular and segmented cabins; the sub-cabin design concept of propulsion cabins, service cabins and communication cabins, so that the platform can adapt to the needs of different payloads;

There are also many innovative technologies, such as large-scale carbon fiber composite light structures; full three-axis attitude track control schemes affected by large-mass liquid shaking and flexible components; dual-component unified propulsion system; frequency multiplexing of payloads, beamforming technology, etc.

Finally, there are two newly completed technologies - advanced automated testing systems with general control and special inspection equipment; as well as full-star EMC test and environmental testing technology without working fluids.

The last two are technologies that have been improved after the deployment of the process quality management system after strict upgrade. With these two technologies, other accidents such as the explosion of Basin are basically bid farewell to the stage of history, and the overall quality of satellites will leap to a new level.

The design service life of "East Three" is 8 years, while the upgraded "East Three B" can reach 14 years.

If the negotiation is completed this time, it will also set a new record - becoming China's first civilian satellite for the whole society. (This chapter ends)
