Due to the small take-off mass of the rocket, the launch frame is also extremely simple, which is some ordinary steel structure, which is mainly used to fill fuel and connect the rocket electrical.

On the 24th, the rocket was already transferred here, and on the 25th, it was erected with a crane and placed on the launch stand.

Not far away, in the open field, two tankers with liquid oxygen and kerosene, will be refueled an hour before launch.

Because the launch site was built in a hurry, the layout of the launch control room was also very simple, and a simple board room was built behind the hill a few hundred meters away.

I have to say that the 30-meter rocket is still spectacular when it stands up, it is 10 stories high, and it can be seen clearly from the top of the mountain.

"It's going to be launched tomorrow, we must do a good job of self-inspection before launching, stop immediately if there is any problem during launch, and dangerous operations are absolutely not allowed, understand?"

Lin Ju was telling Guo Shen and several higher-level technicians that although he wanted the mission to succeed, he never wanted to risk an accident.

Anyway, it is dozens of tons of fuel, and the pit that has been blown up can bury everyone in the factory neatly with the whole family, and the slightest carelessness is a big accident.

"Don't worry, boss, Xinyuan No. 1 is a very mature design, the manufacturing is absolutely up to standard, there are less than 20 hidden dangers found in the four inspections before leaving the factory, and all have been corrected, there is a self-inspection before launch, there will be no problems."

Lin Ju nodded, Guo Shen is at least a former Aramco engineer in the data room, and he should be no stranger to the rocket launch process, he still believes in the judgment of professionals.

"There is also the Propaganda Section, how is the live broadcast equipment prepared, and it will be broadcast live on the whole network at that time."

Cai Yuanfa, who is also the director of the Propaganda Department, patted his chest and packed the ticket:

"Don't worry, Mr. Lin, I asked someone from the TV station to guide me, and there will be no mistakes."

"Satellites, what about satellites?"

Lin Ju turned his head and asked the person in charge sent by the Southern Machinery Institute, who had been in charge of the installation and docking of satellites and rockets in the factory.

"As of yesterday's test, the indicators of the satellite are normal, and the rocket body is well installed, as long as it can be sent, it will definitely be able to be used."

All aspects were prepared, Lin Ju was in a very good mood, and looked at the system panel again.

After a few more manipulations, the settlement gain has increased to 4%, and it is not impossible to increase the popularity accumulated by the live broadcast to 5% or 6%.

At 7 a.m. on August 26, a field of lights was already lit up around the launch site.

All those who participated in the development of rockets and satellites, a total of more than 300 people, gathered on the hill in the control room to watch the rocket on the launch frame together.

Xinyuan-1 will be launched at 11 a.m., at which point repeated self-tests are underway.

Live streaming on major video platforms has begun, but at this time there are only a few hundred people.

But on the road outside the launch site, two people in a car were driving closer with a curse.

"That 'burning torch' is too unreliable, I posted it and didn't reply, and there was no news when I gave an address."

"Didn't he say he was a security guard, maybe he was arrested for leaking."

Do you believe that? He also said that his name was Wang Ergou! ”

"You don't believe it, why are you driving here early in the morning?"

That's right, these two people are aerospace enthusiasts who listened to Lin Ju's post, but not all, because a little later Xinyuanguan V released the launch news, and the launch site is indeed here.

By the time they arrived at the expected place, there were already quite a few people around.

In order to ensure safety, the local government and public security have pulled out a cordon of several kilometers and sent hundreds of personnel to prevent passers-by from breaking in.

Well-informed nearby villagers and people in the town have long known the news through various channels, and they get up early in the morning to watch the rocket.

This was a live view, and the rocket launch was only broadcast live on TV before.

At 9 a.m., the control room approved the refueling.

About 80 tons of fuel were slowly filled into the tank, and the rocket and the launch tower were suddenly covered in white smoke. This is vaporized liquid oxygen, and in order to prevent the tank pressure from being too high, a small part of the vaporized oxygen is continuously discharged.

Rockets of any country, as long as they use liquid oxygen as an oxidizer, can see a constant white smoke drifting out before launch.

Therefore, seeing the white smoke of the rocket means that it is ready for launch and may ignite at any time.

At this time, the popularity of the online live broadcast finally rose, the camera was firmly locked on the rocket, and the number of viewers had swelled rapidly to more than 10,000, and it was still increasing.

Everyone in the control room was extremely nervous, checking the parameters of the rocket over and over again.

60 minutes before launch, another round of self-tests began.

Lin Ju, Tang Weitian, Zhou Rui and others stood on the hill outside the control room, chatting while watching the rocket.

"Lin Ju, in fact, I have always wanted to say something, your rocket engine is very good, but the design of the rocket body is ...... To be honest, there are some problems, not security issues, but other aspects that I don't understand. But at that time you were already in the machining, so I didn't ask. ”

"Oh? Professor Tang tell me quickly, what is the problem? ”

Lin Ju hurriedly asked, Tang Weitian took out a notebook, and said while writing:

"Generally speaking, rockets are designed according to the load target, for example, how many kilograms of payload I want to hit, go to low earth orbit, go to sun-synchronous orbit, or go to the moon, etc., the purpose is different, even if the take-off mass is about the same, the structure will be very different.

If your rocket slightly increases the diameter of the rocket body to 3 meters and the take-off mass is increased by about 10 tons, it can at least increase the low-earth orbit capacity by four times to 1.6 tons instead of the current 400 kilograms, which can only show that the designer's purpose is not actually low-earth orbit.

But I calculated that its sun-synchronous orbit, geosynchronous orbit, and geostationary orbit are not quite right, and they are not like they were designed to be orbital targets.

The design of this rocket is very mature, it is not necessary to sacrifice so much capacity for special purposes, you see that the current Xinyuan-1 actually wastes about 20% of the fuel, and only needs a small change in the mass allocation of the upper stage and the first stage to get several times the capacity increase, I don't believe that its designers can't think of this. ”

"Yes, I thought it might have been a conservative first test, but it was too conservative."

Zhou Rui and others also echoed it, and they also understood it as soon as they heard it.

Lin Ju's heart sank when he heard this, and he hurriedly asked the system in his heart, and the system quickly gave the answer.

The blueprints given by the system come from countless parallel time and space humans, and each earth has a certain difference, and the rocket is not necessarily designed to be launched on the earth.

And the system did not have the ability to modify, so it could only find a rocket that could approximate the requirements, so the DX-1 was thrown out.

So it is clear that the DX-1 is designed to be launched from neither Earth nor Earth orbit, which will lead to a serious reduction in the current carrying capacity.

This kind of mistake is confusing in the eyes of experts, obviously the design of the arrow body is good, how can there be such a low-level mistake?

Lin Ju's mind was running rapidly, and it took a long time to come up with an explanation:

"Ahem, that's Professor Tang, you also know this...... The design of the rocket actually has a little bit to do with the Aramco space agency. ”

Seeing that Tang Weitian and the others around him showed an expression of "so it is", Lin Ju continued to make it up:

"In fact, Xinyuan-1 was changed from the scrapped case of the Aramco space booster, and considering that we have no experience, we hastily used the most conservative changes, just for fear of failure."

This explanation succeeded in fooling everyone, so it can be explained, because the original design of Xinyuan-1 was not a rocket to hit satellites at all.

"I see, it's really Aramco Aerospace, they have really rich design experience, and the level of the people who change it must not be very good, this change is too conservative."

"Yes, such an excellent kerosene machine has been abandoned, it's really too contemptuous of people!"

After Lin Ju personally admitted that the source of the technology was Ami, especially the people in the Sixth Academy were not calm, and their suspicions about themselves were also alleviated a lot.

After all, it is Aramco, who landed on the moon half a century ago, and it is reasonable for them to have such an advanced design, and it is also in line with their arrogance and self-confidence to look down on the 120-ton kerosene engine.

Seeing that he had finally completed the past, Lin Ju breathed a sigh of relief, and hurriedly changed the topic and shifted everyone's attention to the rocket launch.

At 10:55 a.m., 5 minutes before the launch, the last round of self-inspection passed without any faults, and Guo applied for the Lin torch to approve the launch procedure to proceed normally.

In the webcast room, the 5-minute countdown began to beat, and the barrage of video barrage increased rapidly.

At this time, the number of viewers counted by major platforms has exceeded 200,000, but the most active are thousands of students from the South Machine Academy.

After all, if the school relies on this to upgrade the focus, their graduation certificate will also rise with the tide.

Lin Ju glanced at the barrage floating on the laptop, which was roughly "666 of the Southern Institute of Machinery", "I also participated in this satellite", "Praise for the senior", "Huaguo Aerospace refueling", "Xinyuan Tractor Factory NO.1", etc., all looking forward to the successful launch of the rocket.

"60 seconds before launch!"

The broadcast of the transmitting tower emits a chime.

"30 seconds before launch!"

"20 seconds before launch!"

At this time, all the onlookers understood that the next step was the final countdown, and they counted silently in their hearts and stopped talking.

“10，9，8……”

"3, 2, 1, ignition."

"Host ignition."

The last sound fell, and a wisp of white smoke first rose from the bottom of the rocket in the live broadcast magnified footage, and then a beam of flame expanded rapidly.

Before the tail flame expands and the rocket leaves the ground, the smoke spreads around almost the entire body of the arrow, giving the impression of smoke before the explosion.

The crowd of onlookers, who did not know the truth, were nervous, but then the white spike emerged from the smoke and left the ground faster and faster with the body of the arrow behind it.

At this time, the roar of the rocket engine reached everyone's ears, although it was only a 120-ton engine, but the powerful impact made people feel like an earthquake.

Xinyuan No. 1 rose rapidly in everyone's field of vision and flew steadily towards the sky.
