A big country of aerospace with black technology

The propulsion system of the new reusable rocket has jet disturbance problems for two reasons.

The first is the resonance problem between multiple rocket engines, because the number of engines is several times higher than that of the previous domestic mainstream rockets.

The resonance effect between materials is also stronger than a little bit, and it is easy to cause material failure due to resonance.

The second reason is that the control between multiple rocket engines is relatively difficult, and it is difficult for the control system to quickly and dynamically balance the angles of each engine. The jets between the tail nozzles of each engine will interfere with each other, causing disturbances.

These two reasons want to be solved, in addition to testing through a large number of experiments, to find a way to eliminate them.

It is to find a way to establish a simulation model with more detailed conditions, and then conduct simulation analysis through a supercomputer.

If a large number of experiments are used, although a lot of realistic data can be obtained, not to mention the money that needs to be consumed, a large number of experiments will take a lot of time.

Therefore, taking the form of supercomputing simulation analysis simulation model can not only save a lot of time, but also save a lot of experimental funds.

Although Zhang Xingyang managed to get through Mr. Chen, and it took him a long time to use the supercomputer, the time was shorter than expected.

As long as the supercomputer is used for three days, it is 70 hours to be precise.

Therefore, Qiao Yang and the others had to complete the jet flow simulation models of all engine configurations before using the supercomputer.

There are a total of seven sets of structures with different numbers of engines, and a total of 23 design schemes with different numbers and arrangements.

As a master in simulation analysis, Qiao Yang alone undertook the simulation modeling work of six sets of different design schemes.

And it only took him a week to complete these tasks, that is to say, Qiao Yang can basically complete the simulation modeling work of one design scheme every day.

In the entire Rocket Research Institute, apart from Zhang Xingyang who owns Zenith Star technology, only Qiao Yang can reach this speed.

This is also because, with a master like Qiao Yang, all twenty-three designs were completed in less than two weeks.

Because Zhang Xingyang asked Mr. Chen to apply for the "Galaxy-2" supercomputer, which is currently ranked first in the country in the field of national defense scientific research and major project scientific research.

Therefore, in order to be able to use this supercomputer that seems to be very backward in the future, Zhang Xingyang must rush to the location of the computer before November 25th.

Due to the tight schedule, Zhang Xingyang led the team to the experimental center where the "Yinhe-2" supercomputer was located five hours earlier.

The purpose is to be able to start working at the first time when the time has just begun.

Because every minute and second of the "Galaxy-2" supercomputer is precious, almost all scientific research teams using the "Galaxy-2" supercomputer are reluctant to waste a second of time.

They will stay in the experimental center until the last second they can use before leaving.

Zhang Xingyang and the others started at one o'clock in the morning on the 25th.

It was already half a month when the time for using the supercomputer started.

More than half of the team were yawning, but they were still struggling to look at the model data in their hands over and over again.

After waiting for a while, the data of each model was immediately input into the "Yinhe-2" supercomputer to start the simulation analysis.

At twelve o'clock in the middle of the night, several people seemed to be unable to hold on anymore. Zhang Xingyang, Geng Bo, and Qiao Yang, who were the main team leaders, were fine. After all, they used to stay up late to work on projects.

But other people's situation is worse, almost fell asleep looking at the data.

Looking at everyone who was tired, Zhang Xingyang thought for a while, and discussed with Geng Bo:

"Why don't you let everyone go wash your face and eat something to rest?"

"Such a tired state is not suitable for work."

Geng Bo raised his head from the densely packed materials and looked at the people around him who were dozing against the walls.

"Indeed, please contact the experiment center, they should be able to provide some food."

The "Galaxy-2" supercomputer experiment center also provides some life services because everyone cherishes the time of using the supercomputer.

In particular, the supercomputer is turned on almost 24 hours a day, and there are people guarding the supercomputer every minute and every second.

So the cafeteria that is equipped with the supercomputer is also open 24 hours a day, as long as you go to the cafeteria, you can have something to eat.

Zhang Xingyang and Geng Bo persuaded everyone to go to the cafeteria to eat something to rest their stomachs.

After all, after the simulation analysis starts, it is not yet known when there will be time to rest and eat.

And if you are full, your brain will be more active and you will have more energy for thinking.

The experimental center where the "Yinhe-2" supercomputer is located is located in Sichuan Province, so the cafeteria that goes with it is more inclined to the flavor of Sichuan Province.

Zhang Xingyang is from Hunan Province, and he is quite acceptable to the taste of Sichuan cuisine, but there are some Jiangnan people in the team who can't eat spicy food at all, and Sichuan cuisine is not so friendly to them.

Fortunately, in the cafeteria, there was a cook who was good at cooking Shandong cuisine, and he cooked a lot of Shandong cuisine, which gave them a full meal.

"How is everyone doing now?" Zhang Xingyang looked at the rosy-faced people who had eaten enough, "If you are not full, eat more!"

Everyone answered "I'm full." one after another.

Geng Bo even burped.

Zhang Xingyang smiled and said, "You are quite full!"

"That's right, you can't treat your stomach badly anyway!" Geng Bo also said jokingly.

"Seriously, everyone will start working in the next time." Zhang Xingyang became serious after the atmosphere eased a little.

"When we were in the research institute, everyone had already assigned everyone's working hours, and we will strictly follow the schedule."

"Everyone's working hours are very long, and everyone needs to work more than 12 hours a day."

"But for the smooth development of the engine propulsion system, I still hope that everyone will work harder! We will always be with you!"

Zhang Xingyang emphasized the problem of time at work, and by the way, he got a little bloody.

At this time, it was the turn of everyone in the Rocket Research Institute to use the "Galaxy-2" supercomputer.

The staff of the experiment center responsible for the maintenance of the "Galaxy-2" supercomputer came to greet the people of the Rocket Research Institute to use the "Galaxy-2" supercomputer.

Zhang Xingyang looked at the pointer on his watch pointing to one o'clock, and said:

"Let's get to work, everyone!"
