There are two reasons why the propulsion system of the new recoverable rocket has a problem with jet disturbances.

The first is the resonance problem between multiple rocket engines, because the number of engines is several times more 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 fail due to resonance.

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

These two causes 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 use a supercomputer to simulate and analyze.

If you do a lot of experiments, you can get a lot of real-world data, but not to mention the money you need, a lot of time is spent on a lot of experiments.

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

Although Zhang Xingyang tried to get through Chen Lao and reached the use time of the supercomputer, this time was also shorter than imagined.

As long as you get to three days of supercomputing use, 70 hours to be exact.

Therefore, Qiao Yang and they must complete all the jet simulation models of the engine mechanism type before using supercomputing.

There are a total of seven sets of engines with different numbers of structures, 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 was basically able to complete the simulation modeling of a design scheme every day.

In the entire Rocket Research Institute, in addition to Zhang Xingyang, who has Zenith Star Technology, there is only Qiao Yang who can reach this speed.

This is also because, with a big bull like Qiao Yang, all the twenty-three design plans took less than two weeks to complete.

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

So in order to be able to use this supercomputer, which seems to be very backward in the future, Zhang Xingyang must arrive at the location of the computer by November 25.

Because of the tight time, Zhang Xingyang led the team to arrive at the experimental center where the "Galaxy-2" supercomputer was located five hours ahead of schedule.

In order to be able to start working as soon as the time has just begun.

Because every minute and second of the use 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's starting time was at one o'clock in the morning on the 25th.

This day is a tiring journey, and when the supercomputing time begins, it is already half a month.

Most of the team yawned, but they struggled to look through 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 "Galaxy-2" supercomputer and began to simulate and analyze.

At twelve o'clock in the middle of the night, several people seemed to be almost unable to hold on, Zhang Xingyang, Geng Bo, and Qiao Yang, who were the main leaders of the team, were okay, after all, they were all people who often stayed up late to do projects before.

But the others are in a worse situation, almost falling asleep looking at the data.

Looking at the tired everyone, Zhang Xingyang thought about it and discussed it with Geng Bo:

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

"This kind of fatigue is not suitable for work."

Geng Bo looked up from the dense crowd of information and looked at the people around him who were dozing off against the wall.

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

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

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

Therefore, the cafeteria that is equipped with the supercomputer is also open 24 hours a day, and 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 and pad their stomachs.

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

And when you are full, your brain will be more active and you will be able to have more energy to think.

The experimental center where the "Galaxy-2" supercomputer is located is located in Sichuan Province, so the canteen supporting it is also more inclined to the flavor of Sichuan Province.

Zhang Xingyang is a native of Hunan Province, and he is quite acceptable to the taste of Sichuan cuisine, but there are still 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 canteen, there is also a cook who is good at making Lu cuisine, and he has made a lot of Lu dishes, which made them have a full meal.

"How's everyone doing now?" Zhang Xingyang looked at the people with ruddy faces who had eaten a full meal, "If you don't have enough to eat, eat more!" ”

One after another, the crowd replied, "I'm full." ”。

Geng Bo even hiccuped.

Zhang Xingyang smiled and said, "You're quite full!" ”

"That's, no matter what, you can't treat your stomach badly!" Geng Bo also said jokingly.

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

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

"Everybody's working long hours, everybody has to work more than twelve hours a day."

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

Zhang Xingyang emphasized the time problem at work, and by the way, he played a little chicken blood.

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

The staff of the experimental center, who is responsible for the maintenance of the "Galaxy-2" supercomputer, came to call the personnel of the Rocket Research Institute to use the "Galaxy-2" supercomputer.

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

"Let's get to work!"
