The place where the test video was filmed was actually the rocket test site of Lao Yang and others, located in an abandoned factory.

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

It's just that their test equipment has never tested such a large thruster, so I don't know if it's up to the task.

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

Tang Chao patted the thruster next to him, "After this thing is ignited, the movement must be very large, it is not comparable to the small engines you played before, don't call the police." ”

"Don't worry, engine testing is dangerous, so we looked for a place that is remote enough and quiet around."

Lao Yang turned his head and glanced at him and said.

Tang Chao nodded when he heard this, just be safe.

Whether it is watching the relevant video at Bizhan or watching the scene at Kanxing, the movement of the ignition of the solid rocket thruster is much more than the movement of the liquid engine.

Liquid ignition is a beam of flames, except for the larger one, there is nothing else, only after encountering the cooling pool will appear "smoke billowing" effect, solid push is different, this thing comes with smoke billowing special effects.

And at first glance, it's the kind that has a lot of money.

As the car walked, Lao Yang pointed forward, "Look, it's here." ”

Tang Chao looked in the direction of his finger, and sure enough, he saw an abandoned factory, and they walked all the way, the surrounding area was indeed very desolate, and there were no people.

This he is relieved, this place is basically done casually, they are only conducting ground tests, not launching rockets, and they don't have to worry about the aviation identification area and aircraft routes.

The car drove into the factory, and Tang Chao also saw the test rack they said.

"This test bench is ...... Utility. ”

Tang Chao held back for a long time and held back such a sentence.

Lao Yang slapped him directly on the back when he heard this, "If you want to say that it is simple, let's say it directly, we want to build a professional test bench, but we have no money and no technology, it would be good to have an iron frame, what kind of bicycle do you want." ”

"I didn't say it's simple, I really feel very practical." Tang Chao grinned when he was photographed, but he still insisted on his opinion.

Lao Yang didn't want to talk to him anymore, and urged: "Okay, what's the matter, hurry up and install the engine on the 'practical' test bench, and it will be dark in a while." ”

“……”

As when they arrived, the amateur rocket team was still excited, and with a violent operation, the FM1 "Mites" solid-fuel thrusters from the world of Cannes were mounted on the steel frame.

This steel frame looks very solid with materials, they should have made it themselves, Tang Chao found traces of welding, and screws were added in some places.

It is generally fixed next to a large cement platform, and the propeller is fixed horizontally so that the spout is facing outward, and the other end is against the cement platform.

He didn't know how heavy the cement platform was, but it certainly wasn't something that could be shaken by a ton of thrust.

He was relieved.

Unzipped his school bag, took out a bunch of equipment, including signal transmission, pressure measurement, temperature measurement, ignition and other devices, and asked the team to install them on the thrusters, while he began to set up the video recording equipment himself.

When shooting a test video, there must be more than one lens, what is far and near, side-right, up, down, left and right......

It has to be photographed from all directions.

When the team members installed the equipment, they found that there was a problem, that is, Tang Chao's things were much more professional than they imagined, and they were like things they got directly from a professional aerospace company.

After discovering this problem, several people got together and talked about it while installing it.

"This Brother Tang is well hidden, how did you get these things?"

"That's it, Brother Yang, you know him very well, do you know his way? Let him introduce it, and we'll buy a set too. ”

"Can we afford it?"

“……”

In a word, a few people were cold.

"Ahem, or Brother Yang, after completing the test, you ask Brother Tang, let's borrow this set of test equipment, this unexpected overtime is because the previous test error is a bit big, so it caused a chain error in the later stage."

"Yes, yes, if we test it again with these devices, we should have a high success rate this time."

Lao Yang nodded when he heard this, according to his understanding of Tang Chao, there should be no problem, so he said, "Okay, I'll ask when the time comes." ”

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

At first, they found that the workmanship of this thruster was very fine, and they also knew that Tang Chao had the skill of making models, thinking that it was just a spectacle, but now that the test equipment is so professional, they have to think of more things.

"This thruster can't really reach a ton of thrust like in the game, right?"

"If it can reach one ton, the fuel there will definitely not be the kind of 'fertilizer' we play, I wonder if it is a solid fuel used by professional institutions?"

"Hey, Tang Chao really has this way? Do you want him to get us some professional fuel? ”

"What about professional fuel, aren't you afraid to go in and drink tea?"

"Tang Chao, it's not okay......"

While speaking, 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 the thrusters could not be seen.

Kanxing Technology is great, but the rocket is really dangerous, not to mention that he still got it from another world, and it's hard to say whether it adapts to the environment of the earth.

If this explodes, the 300 kilograms of fuel in it are no worse than the 300 kilograms of explosives.

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

It was getting close to evening, and only some afterglow of the sun could be seen in the west, and the experienced Lao Yang felt that everything was almost ready, so he nodded and signaled that Tang Chao could start.

Tang Chao saw a lot of test scenes in Kanxing, but he was really a little nervous when he came to Earth so suddenly, and asked him to press the start button.

However, he also wanted to see how these things performed on Earth, after all, this was not an Earth Technology mod like the Long March 9, but the original Canxing Technology.

"Click~"

The enter key was pressed accurately by Tang Chao.

Everyone is glued to the surveillance footage.

In the surveillance footage, the ignition device inserted into the thruster nozzle shook slightly, and then the thing used to seal the spout immediately shattered and flew out.

They soon saw a little light in it, and then the light turned into flames, and the flames turned into flames.

Finally, a violent squirt out of the spout!

"Boom-"

A huge roar came from the test site, even if it was separated by a few walls, Tang Chao and the others could hear it clearly, and then, they felt that the ground was shaking.

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

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

"it, cow batch!"

"Look at the data, how's the data going?"

"The data is very stable, there are no anomalies!"

"The thrust has also stabilized, reaching 1.1 tons!"

"Cow Pi, amazing!"

"This thrust, two more levels will definitely be able to cross the Kármán line, right?"

"It's definitely no problem, take a good look at it, maybe you can get into orbit."

They are lively here, and the scene is even more lively.

The thruster spout spewed out blazing flames and billowing exhaust fumes, directly blowing the camera behind the camera and the soil, and the clods and gravel flew around, like bullets, and smashed around.

Moreover, the jitter of the steel frame is getting worse and worse, and even some places begin to twist, solder joints crack, and screws loosen, which further aggravates the jitter range of the steel frame and the thruster.

The direction of the thruster's jet is uncontrollable.

"Suffer, the steel frame is not strong enough!"

"Get out of here!"
