Hearing Wu Hao's complaints, Yu Chengwu smiled and explained: "In fact, it has been maintained, but the entire shell has not been cleaned and painted. In fact, under normal circumstances, the impact is not big. Anyway, after one or two launches, it will become Such a ghost look.
Like this six-handed first-stage rocket body, it will be retired after a few more missions, so there is no need to repaint 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 situation does affect the perception, and it really shouldn't be.
Don't worry, I will definitely criticize and educate them when I go back. These people are too bad. "
Okay, stop acting in front of me. Looking at Yu Chengwu's poor performance, Wu Hao couldn't help but rolled his eyes and said angrily.
Haha, Yu Chengwu was not embarrassed after hearing his words. Instead, he 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 No matter what the use is, everyone just doesn’t pay much attention to it.”
"This is what's in my heart." Wu Hao pointed at him with his finger.
Yu Chengwu smiled sheepishly at him and continued: "Actually, there is another reason, that is, the burnt and blackened marks on the bodies of these rockets can also explain to the outside world the outstanding achievements of this rocket. . If it were refreshed, wouldn't it mean that all these achievements would be lost? Even if we list them out, it won't be very convincing. Only such an original arrow body can convince everyone.
Look at those Falcon Rockets, they are not painted. "
Haha, the feelings are copied, okay, although this reason is far-fetched, it is still a reason. Wu Hao nodded slightly, and then continued to look at the big screen.
In the main screen window, the rocket is completely exposed, with only the swing rod and cables connected. Unlike ordinary Ice Rockets, which are liquid hydrogen and oxygen rockets, the Jianmu-2 rocket, which uses semi-solid foam material, is completely a normal-temperature rocket, so there is no white smoke coming out of the rocket body.
Moreover, the Jianmu-2 rocket using this semi-solid foam fuel can be stored for a long time after the fuel is injected. In other words, it can be filled in advance like a solid-state rocket, and then stored, transported, and launched in an emergency.
Of course, compared to solid fuel, this semi-solid foaming fuel also has some disadvantages. For example, the thrust is weak with solid fuel, which is caused by the density of the fuel. In addition, after the filling of this semi-solid foamed fuel is completed, transportation may not be as convenient and safe as solid fuel. And it is volatile, so improper storage may lead to leakage, and there are also risks such as fire and deflagration.
In the smaller window picture 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 and technical personnel and the rocket and satellite technical teams have already taken their seats and are concentrating on the various changing data flashing on the screen. The atmosphere is very solid.
Although for launch personnel, such launches are commonplace. But this launch mission is quite special. On the one hand, this is a new rocket, and it is also a new rocket that is completely different from traditional launch vehicles, so the launch procedures, flight parameters, and other aspects are very different.
Secondly, except for the upper stage and the two satellites above the upper stage of the rocket launched this time, the entire rocket, including the first and second stages of the rocket and the fairing, will return to the earth for landing and be reused. This means that the entire rocket can be recycled and reused. This is a truly reusable launch vehicle.
As time passed by, the atmosphere in the command, control and management center of the Yatu Sea Landing Field became tense.
Everyone is focused on their work. In addition to the sound of keyboards and instruments, there are also people moving around in the hall, as well as the sound of announcements on the radio.
Ten minutes to prepare!
As this voice came from the radio, the entire Yatu Sea Landing Field Command, Control and Management Center hall became commotion and then became quiet again.
Wu Hao looked at the countdown numbers on the big screen and felt nervous. No matter how many times he has been to the launch site or watched the launch process, he can't help but get nervous every time the countdown comes.
Because everyone knows that rocket launch is a high-risk industry, and the success rate is always only 50%, or even lower. No one can guarantee that a launch will be foolproof.
Therefore, even experienced veteran aerospace personnel are extremely serious and nervous when facing every launch mission. A little carelessness, one data or even a decimal point, may cause the entire task to fail.
There are so many examples of such failures that no one dares to let down their guard. Whether it is a manned launch or an ordinary payload, it is the same. Concentrate and take it seriously.
Five minutes to prepare!
As the broadcast rang, everyone knew that this had reached the most critical moment. Ever since, everyone held their breath and concentrated to welcome the last moment.
Because it is a new type of rocket, no one knows whether the launch will be successful. If the launch cannot be successful, let alone the subsequent return and landing experiment.
Wu Hao glanced at Yu Chengwu next to him and found that this guy could not help clenching his hands at this moment. His eyes were fixed on the big screen, for fear of missing any books. Compared to him, Yu Chengwu was obviously more nervous and focused at this 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 view this mission more calmly. He will naturally be happy if he succeeds. If there is a bad result in the end, he will have to come out to clean up the mess and comfort everyone. This is what he has to do as a leader, and it is also a big reason why he came to the scene this time. One of the purposes.
One minute to prepare.
Thirty seconds!
Ten, nine, eight...three, two, one, ignition, take off!
Dongfeng program takes a turn!
As huge flames erupted from the bottom of the rocket, the entire Jianmu-2 T-type carrier rocket slowly rose into the sky. 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 feel the shock of this rocket launch immersively.
The camera zoomed out, and above the desert wall where the sky was slightly bright, a rocket was slowly rising into the sky, dragging flames and hitting the sky!
