Military Technology

Hearing Wu Hao's complaints, Yu Chengwu explained with a smile: "Actually, it has been maintained, but the entire shell has not been cleaned and painted. In fact, under normal circumstances, it has little effect. Anyway, after one or two launches, it will become This ghost looks.

Like this six-handed first-stage rocket body, it will soon be retired after a few missions, and there is no need to re-paint its rocket body. "

Speaking of this, Yu Chengwu changed his tone and said: "However, such an important experiment will definitely attract the attention of all parties. The current appearance does affect the perception, and it really shouldn't be.

Don't worry, I will criticize and educate me when I look back, these people are too bad. "

Okay, stop acting in front of me. Seeing Yu Chengwu's clumsy performance, Wu Hao rolled his eyes and didn't have a good air.

Hehe, Yu Chengwu was not embarrassed after hearing his words, but smiled and said to Wu Hao: "Pragmatism, this is what you have always conveyed to all of us, and it is our company's corporate culture. So things like these are not What's the use, everyone didn't pay much attention to it."

"That's what's in my heart." Wu Hao pointed at him with his finger.

Yu Chengwu smiled embarrassedly at him, and continued: "Actually, there is another reason, that is, the burning and blackening marks on the body of these rockets, which can also explain to the outside world the outstanding achievements of this rocket before. If it is refreshed, it means that all these achievements will be wiped out. Even if we list it, it is not very convincing. Only such an original arrow body can convince everyone.

If you look at the Falcon rockets, they are not painted. "

Hehe, feelings are copied, okay, although this reason is far-fetched, it is also a reason. Wu Hao nodded slightly, then continued to look at the big screen.

In the main screen window, the rocket is completely exposed, and only the pendulum and cables are connected. Different from ordinary ice rockets, that is, liquid hydrogen-oxygen rockets, the Jianmu-2 rocket using semi-solid foam materials is completely a rocket at room temperature, so there is no white smoke gas on the rocket body.

Moreover, the Jianmu-2 rocket using this semi-solid foamed fuel can be stored for a long time after fuel injection, that is to say, it can be refilled in advance like a solid rocket, and then can be stored and transported for emergency launch.

Of course, this semi-solid foamed fuel also has some disadvantages compared to solid fuels. Such as weak thrust and solid fuel, which is caused by the density of the fuel. In addition, once this semi-solid foamed fuel is filled, it may not be as convenient and safe to transport as solid fuel. And it itself is volatile, so improper storage may lead to leakage, and there are risks such as fire and explosion.

In the smaller window next to it, there is a picture of the launch command and control hall of the Northwest Launch Center. At this moment, the launch engineering technicians and the rocket and satellite technical teams are already seated, and they are concentratingly watching the various changing data flashing on the screen, and the atmosphere is very solidified.

Although for launch crews, such launches are commonplace. But this launch mission is rather special. On the one hand, this is a new rocket, and it is a new rocket that is completely different from traditional launch vehicles, so the launch procedures, flight parameters, and other aspects are very different.

Secondly, the rocket launched this time, except for the upper stage and the two satellites above the upper stage, the entire rocket, retains the first and second rockets, and the fairing will return to the earth for landing and reuse. This means that the entire rocket can be recycled and reused, which is a reusable launch vehicle in the true sense.

As time progressed minute by minute, the atmosphere in the command and control management center of the entire Yatuhai landing site also became tense.

Everyone was fully focused on their work. In addition to the sounds of keyboards and instruments, the entire hall was the movement of people and the sound of announcements in the broadcast.

Ready in ten minutes!

With the sound coming from the broadcast, the hall of the command and control management center of the Yatuhai Landing Field rioted for a while and then became quiet again.

Wu Hao looked at the countdown number on the big screen, and his heart couldn't help but get nervous. No matter how many times he was at the launch site and watched the launch process, every time the countdown came, he couldn't help but get nervous.

Because everyone knows that rocket launch is a high-risk industry, the success rate is always only 50%, or even lower, no one can guarantee that a launch will be foolproof.

Therefore, even experienced and old astronauts are extremely serious and nervous in the face of each launch mission. It may be a little careless, a data or even a decimal point, it may cause the entire task to fail.

There are so many failures like this that we never dare to let our guard down. Whether it's a manned launch or a normal payload, it's the same, focus and take it seriously.

Ready in five minutes!

As the broadcast sounded, everyone knew that this was the most critical time. So, everyone held their breaths to welcome this last moment.

Because it is a new type of rocket, no one knows whether the launch will be successful. If the launch can't be successful, let alone the subsequent return landing experiment.

Wu Hao glanced at Yu Chengwu next to him and found that this guy clenched his hands tightly at the moment. His eyes were staring straight at the big screen, for fear of missing any books. Compared to him, Yu Chengwu was obviously more nervous and focused at the moment.

Wu Hao did not disturb him, but continued to stare at the big screen with a smile. Although he was a little nervous, he was able to look at this mission more peacefully. He is naturally happy and happy when he succeeds. In the event of a bad outcome, he will have to come forward to clean up the mess and comfort everyone. This is what he has to do as a leader, and it is also a big part of his visit to the scene this time. one of the purposes.

One minute to prepare~www.readwn.com~30 seconds!

Ten, nine, eight...three, two, one, fire, take off!

Dongfeng program turns!

As the huge flames spewed out from the bottom of the rocket, the entire Jianmu-2 T-type launch vehicle slowly rose into the sky, and the air waves generated by the huge flames shook the images captured by the surveillance cameras installed on the towers.

And this kind of picture vibration can also make everyone in the hall of the command and control management center of the Yatuhai landing site hundreds of kilometers away to feel the shock of this rocket launch.

The camera is zoomed out, and next to the slightly bright desert, a rocket is slowly lifting off with flames, hitting Jiuxiao!
