Super technology leader

The place where they were shooting the test video was actually Old Yang and the others' rocket test site, located in an abandoned factory.

They were working on amateur rockets and needed a fixed and safe place for ground testing, and it took them a long time to find this abandoned factory.

However, their testing equipment had never tested such a large booster before, and they didn't know if it could handle it.

"By the way, there's nothing around that abandoned factory, right?"

Tang Chao patted the booster next to him, "This thing will definitely make a lot of noise when it ignites, it's not like those small engines you guys played with before, don't attract the police."

"Don't worry, engine testing is very dangerous, so the place we found is remote enough, and the surroundings are very quiet."

Old Yang turned his head and said to him.

Tang Chao nodded upon hearing this, as long as it was safe.

Whether watching related videos on Bilibili or seeing the live scene in Kerbal Space Program, the sound of a solid rocket booster igniting is much louder than that of a liquid engine.

Liquid engine ignition is just a stream of flame, nothing else except being a bit bigger, and only after encountering a cooling water pool will the effect of "thick smoke billowing" appear, but solid rocket boosters are different, this thing comes with thick smoke billowing effects.

And it looks like it has a particularly sufficient budget.

As the car drove, Old Yang pointed forward, "Look, we're here."

Tang Chao looked in the direction of his finger and saw an abandoned factory building, and they had indeed passed through a desolate area with little population.

This put him at ease, they could basically do whatever they wanted here, they were just doing ground tests, not launching rockets, so they didn't have to worry about aviation identification zones and aircraft routes.

The car drove into the factory, and Tang Chao also saw the test stand they mentioned.

"This test stand is very... practical."

Tang Chao struggled for a long time before squeezing out this sentence.

Old Yang slapped him on the back upon hearing this, "If you want to say it's crude, just say it directly. We wanted to build a professional test stand, but we don't have the money or the technology. Having an iron frame is good enough, what more could you want."

"I didn't say it was crude, I really feel it's very practical," Tang Chao grimaced from the slap, but still insisted on his point of view.

Old Yang didn't want to talk to him anymore and urged, "Alright, stop talking nonsense, quickly install the engine on the 'practical' test stand, it will be dark in a while."

"..."

As when they arrived, the amateur rocket team was still very excited. After a series of fierce operations, the FM1 "Mite" solid fuel booster from the Kerbal Space Program world was installed on the steel frame.

The steel frame looked like it was made of solid materials and should have been made by themselves. Tang Chao found traces of welding, and some places were screwed together.

It was generally fixed next to a large concrete platform. After the booster was fixed horizontally, the nozzle was facing outwards, and the other end was against the concrete platform.

He didn't know how heavy the concrete platform was, but it definitely couldn't be shaken by a one-ton thrust.

This put him at ease.

He opened the zipper of his backpack and took out a pile of equipment, including signal transmission, pressure measurement, temperature measurement, ignition and other devices, and asked the team to install them on the booster, while he began to set up video recording equipment.

When shooting test videos, there must be more than one camera, with different distances, sides, fronts, up, down, left, right, etc.

All angles must be captured.

When the team members were installing the equipment, they discovered a problem, that Tang Chao's things were much more professional than they had imagined, almost like they were taken directly from a professional aerospace company.

After discovering this problem, several people gathered together and whispered while installing.

"This Brother Tang is really hiding something, how did he get these things?"

"That's right, Brother Yang, you're very familiar with him, do you know his connections? Ask him to introduce us, we also want to buy a set."

"Can we afford it?"

"..."

One sentence silenced several people.

"Cough, Brother Yang, why don't you ask Brother Tang to let us borrow this set of testing equipment after the test is completed? This unexpected overtime work is because the previous test errors were a bit large, which caused a chain of errors in the later stages."

"Yes, yes, test it again with these devices, our success rate this time should be very high."

Old Yang nodded upon hearing this. According to his understanding of Tang Chao, it should be no problem, so he said, "Okay, I'll ask then."

Because of the professionalism of the equipment, they were even more looking forward to this test.

In the beginning, they found that the booster was very well-made, and they also knew that Tang Chao had the skills to make models, and thought it was just a showpiece, but now that the testing equipment was so professional, they couldn't help but think of more things.

"Could the thrust of this booster really reach one ton like in the game?"

"If it can reach one ton, then the fuel inside must not be the 'fertilizer' we play with. I wonder if it is solid fuel used by professional institutions?"

"Hey, does Tang Chao really have this kind of connection? Should we ask him to get us some professional fuel?"

"Still professional fuel, aren't you afraid of going in for tea?"

"Tang Chao is fine..."

While they were talking, all the preparations were completed, and Tang Chao also took out his laptop, connected all the equipment signals, and hid with them in a corner where they couldn't see the booster.

Kerbal Space Program technology is great, but rockets are indeed dangerous, not to mention that he got this from another world, and it's hard to say whether it's suitable for the Earth's environment.

If it explodes, the three hundred kilograms of fuel inside is no less than three hundred kilograms of explosives.

The laptop screen was divided into two parts, one side was multiple video screen windows, and the other side was a recording window for various data.

The sky was approaching dusk, and only some afterglow of the sun could be seen in the west. The experienced Old Yang felt it was almost time. Everything was ready, so he nodded to signal Tang Chao to start.

Tang Chao had seen many test scenes in Kerbal Space Program, but actually doing this on Earth, and having him press the start button, he was really a little nervous.

But he also wanted to see how these things would perform on Earth. After all, this was not a Earth technology mod like the Long March 9, but an original Kerbal Space Program technology.

"Click~"

The enter key was accurately pressed by Tang Chao.

Everyone stared at the monitoring screen.

In the monitoring screen, the ignition device inserted into the booster nozzle trembled slightly, and then the things used to seal the nozzle immediately shattered and flew out.

They soon saw a glimmer of light inside, then the light turned into a flame, and the flame turned into a raging fire.

Finally, it spewed out violently from the nozzle!

"Boom——"

A huge roar came from the test site. Even through several walls, Tang Chao and the others could hear it clearly. Then, they felt the ground shaking.

Looking up at the other side of the wall, white smoke rose!

This movement was much louder than the previous tests by the amateur rocket team, so before Tang Chao could say anything, they jumped up first.

"Holy crap, awesome!"

"Quick, look at the data, how's the data?"

"The data is very stable, no anomalies!"

"The thrust is also stable, reaching 1.1 tons!"

"Awesome, amazing!"

"With this thrust, adding two more stages will definitely pass the Karman line, right?"

"Definitely no problem, if we do it well, we might be able to enter orbit."

It was lively here, and the scene was even more lively.

The booster nozzle spewed out hot flames and billowing exhaust gas, directly blowing away the rear lens along with the soil. Fragments of soil and gravel flew around like bullets, hitting the surroundings with a bang.

Moreover, the steel frame shook more and more violently, and even some places began to twist, solder joints cracked, and screws loosened, which further aggravated the shaking range of the steel frame and the booster.

Seeing that the injection direction of the thruster is uncontrollable.

"It's going to be bad, the steel frame is not strong enough!"

"Get out of here!"
