Riding the wind of rebirth

The next morning, Li Laoer, Li Laosan and Li Weigang also came to the institute. Also arriving were several old soldiers with a strong academic flavor, but wearing military uniforms and having ridiculously high military ranks.

According to Li Weigang, these people are all veteran experts and leaders of the Commission of Science and Technology.

This unit is a bit exaggerated. The current Science and Technology Commission has enormous power. It will not be dispersed a little until after the institutional reform next year.

However, whether now or after the institutional reform, one of its functions is to formulate industrial and technological policies and development plans for the nuclear, aerospace, aviation, shipbuilding, and weapons industries, implement industry management, and guide the industry management of military electronic products.

Another function is to manage 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, which means that there is a layer of management relationship between it and these old leaders and it is a subordinate of subordinates.

Zhou Zhi finally understood why he was pulled here to discuss things. It all fit in!

"Is Xiao Miao an American?" The old experts looked at Zhou Zhi and Mai Xiaomiao with a kind look. One of them asked, "Who else is there?"

“And mom and dad.” Mai Xiaomiao said.

"That's not easy. You gave up your comfortable life to help us build our discipline."

"Actually, my life there is not as good as here." Mai Xiaomiao glanced at Zhou Zhi and said, "There are many people here who take care of me. I live happily here. At least I don't live on two sandwiches a day."

"Haha, that's good. We were worried that you wouldn't be used to the life here, so we told you to just let us know if you have any requests." An old man was amused by Mai Xiaomiao's straightforward words: "Our Chinese food is pretty good. When I was studying abroad, what I missed most was a bite of my hometown noodles with soy sauce!"

“Yes, after eating the Kung Pao Chicken made for me by Elbow Pork, I realized that the Kung Pao Chicken sold abroad is a rip-off!” Mai Xiaomiao protested indignantly.

"Hahahaha..." Everyone laughed. An old man asked, "Is this the pork elbow that made your Kung Pao Chicken? Does he make your life very happy?"

Mai Xiaomiao was not shy at all, and even seemed a little proud, showing off: "Well, elbow is the best for me!"

Now everyone was happier, but they no longer laughed as loudly as before, as if they were afraid that laughing too exaggeratedly would embarrass the children and keep away from each other.

"The elbow is also good." Qin Haifeng praised: "Not only has it published information technology engineering management textbooks, but it has also been used in practice. In combination with the foreign ISO quality certification system, it has helped several of our units develop a process quality control system."

"Yes, in the most recent launch, despite the desperate situation of the explosion of the Pakistani star, we were able to send the Australian star to the intended orbit and operate normally. This is the great 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 rolled out at the base and is also being actively promoted to 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 Ship Research Institute introduce cavitation simulation, and finally let Elbow introduce us to the quality management system and process quality control, how about it?"

"If time is not sufficient, we can discuss our matter at another time." Li Laoer was very obedient. He could see that the experts were temporarily interested in Zhouzhi's process quality management system. It was an unplanned arrangement, and he was afraid that they would not have enough time.

"No, no, no, your business is also important." An old man quickly waved his hand.

Another old man laughed and said, "It should be said that it is more important. Without your patronage, we would be losing money!"

Seeing this, Zhou Zhi knew that Li Lao Er had almost finished talking with these people. Today was more of a conversation to further strengthen the relationship, mainly to brag about the quality of their satellites and the reliability of rocket launches. Just seeing that these people were sent to "strengthen confidence" for him, Zhou Zhi knew that the country was determined to win.

If it were a normal business behavior, you would have to understand the other party's mentality and bargain at this time.

However, several people on Zhou Zhi's side were unable to do this. Firstly, the price was already cheap enough, and secondly, the cooperation between the two parties was already very harmonious. The things Zhou Zhi had given away were not few, but the Clover Group had actually reaped a lot of rewards, so there was no need to be too picky about it.

However, the introduction to the Dong-3B satellite made Zhou Zhi quite surprised by its superior design performance.

This satellite has reached the most advanced level among similar medium-sized capacity satellites in the world.

卫星上有24路C频段转发器，其中6路为中功率转发器；其它18路为低功率转发器。在地影期间，全部转发器均可工作。卫星寿命末期输出功率≥1700W：卫星允许的有效载荷质量达170kg。

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

In other words, Dong-3 was designed from the beginning to serve as a "large cabinet", which has greater adaptability and can be used for a variety of satellites with different payloads within a certain weight and power consumption range.

Whatever equipment the designers later installed in this cabinet, it could become any other kind of satellite - it could be transformed into a lunar exploration vehicle, a networking navigation satellite, a military remote sensing satellite, etc. This could shorten the development cycle and improve cost-effectiveness.

It also created many design firsts.

For example, it is China's first geostationary orbit satellite that has made the leap from spin-stabilized to three-axis-stabilized.

In the past, satellites were rotating in space. In order to keep the satellite functioning, it was necessary to design three working surfaces so that one side of the satellite would always be facing the earth during the rotation process.

However, three working surfaces require three sets of equipment, and at least some facilities must be designed in three sets, which will undoubtedly increase the satellite's payload and power consumption.

After achieving three-axis stabilization, the satellite's east-west and north-south position errors can be made ±0.1°, and the antenna's pitch and roll errors can be ±0.15°. Therefore, only one working surface needs to be designed. The platform itself can ensure that this working surface is always aligned with the earth at an extremely high longitude. In addition to ensuring operational stability, it also reduces power consumption. The saved payload and space can be used to install other components, which in turn improves the satellite's performance.

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

For example, large-scale carbon fiber composite lightweight structure; full three-axis attitude and orbit control scheme affected by large-mass liquid sloshing and flexible components; dual-component unified propulsion system; frequency multiplexing and beamforming technology of payload, etc.

Finally, there are two technologies that have just been completed - an advanced automated testing system for master control and special inspection equipment; and full-star EMC testing and environmental testing technology without working fluids.

The last two technologies were improved and completed after the deployment of a strictly upgraded process quality management system. With these two technologies, accidents such as the one that caused the explosion of Baxing will basically bid farewell to the stage of history, and the overall quality of the satellite will leap to a new level.

The design service life of "Dong San" is 8 years, while the upgraded "Dong San Yi" can reach 14 years.

If the deal goes through, it will also create a new record - becoming China's first civilian satellite for the entire society. (End of this chapter)
