In the next few days, Wang Bin went to the rocket manufacturing factory every day to check the manufacturing progress of the rocket. Finally, after a long wait, a huge rocket was successfully erected on the launch pad by Tiangong Technology. The spacecraft to be launched has also been installed in the fairing on the top of the rocket at this time, just waiting for the day of the rocket launch.

Of course, as a private enterprise, Tiangong Technology should not be too picky about the launch time. However, in order to improve the success rate of the rocket launch, it is natural to choose a sunny day for launch. Otherwise, if the weather is bad, The success rate of the launch will naturally drop greatly, which will pose a great risk.

After all, not to mention other things, the cost of this Tiangong-4 rocket body is very high, not to mention the spacecraft above.

Fortunately, although the rainy season in the south has arrived, most of the time during this period is cloudy and rainy, but the weather will clear up one day later, and according to the weather forecast, the wind on this day is also very moderate. Good day to launch a rocket.

Therefore, Wang Bin and the others immediately decided to launch the rocket in the afternoon of the day after tomorrow.

At the same time, they also began to conduct more detailed inspections of the rocket.

Finally, the time came for the day when the rocket was about to launch. Since this launch was the first heavy-duty rocket developed and manufactured by Tiangong Science and Technology, there was no one except Wang Bin himself and the launch crew.

All the employees and technicians from the rocket manufacturing factory and the rocket engine laboratory have come to the rocket launch site, and even the Tiangong Technology headquarters, except for the necessary positions, most of the personnel have come to the rocket launch site Live, come and watch this rocket launch.

Moreover, in addition to Tiangong Technology's own employees and the rocket launch and inspection technicians sent by the government, Wang Bin and the official leaders of the county, city, and even the province where Tiangong Technology is located also came to watch the sky in person. This launch of engineering technology.

Of course, in fact, this is not the first time they have come to Tiangong Technology to watch the rocket launch. After all, since the first rocket launch of Tiangong Technology was successful, the rocket launch site of Tiangong Technology has been used by many people in the province. well known.

After all, it is impossible to hide such a big movement of launching a rocket.

Although, in the next few launches, Wang Bin did not open to the public, nor did he announce it to the public. Only after the launch was successful, the official release of relevant news.

But when the rocket was launched, many people still noticed the situation here, and some people nearby even took a special video.

Seeing this situation, after discussing with the officials from Tiangong Technology, Mr. Qin and other officials from the aerospace department, Wang Bin and the others simply stopped blocking the launch situation and opened up the launch site of the rocket.

Of course, for those places that want to keep secret, Tiangong Technology will not announce it to the public, such as the rocket manufacturing factory and the rocket engine laboratory.

After all, the rocket manufacturing factory, rocket engine laboratory and other related laboratories are the top priority of Tiangong Technology's rocket development and manufacturing, and it is absolutely impossible to disclose it to the public, even to the official, it is not completely disclosed.

Of course, even if they have opened the rocket launch site to the public, people who come to watch the rocket launch cannot enter within two kilometers of the rocket launch site. After all, rocket launches are very dangerous, even if they are The control room where the rocket launch controllers are located is also nearly one kilometer away from the rocket launch pad.

The most important thing is the side of the rocket launch control room,

The thickness of the special cement protective wall outside alone has reached as much as two or three meters, and the outside of these cement walls is also wrapped with a thick layer of sound insulation and anti-seismic and special steel materials to protect the safety of the internal personnel.

It can be said that the personnel inside the control center are very safe. Even if the rocket falls directly on top of the control center during launch, the control center can also protect the safety of the personnel inside to the greatest extent. Safety.

So at this time, neither Wang Bin nor everyone in the control room were worried about the safety of the people inside the control room.

On the contrary, Wang Bin was more worried about the safety of the personnel outside the control room, which is two kilometers away from the launch pad, who came to watch the rocket launch.

However, since these people are two kilometers away from the rocket launch pad at this time, their safety is still very high.

Because of such a long distance, even if the diameter of the rocket is on the launch pad, something goes wrong and it explodes, it will not have much impact on the people two kilometers away.

Moreover, even if there is a problem in mid-air after the rocket is launched, the detonating device inside the rocket will detonate the fuel inside the rocket as soon as possible, and let it burn directly in the air. As for the spacecraft on the rocket, it will also be the first time Time to separate, and deploy the parachute, then proceed to recovery.

It can be said that in terms of safety, Tiangong Technology is still doing a very good job.

Of course, Wang Bin still felt a little dissatisfied with this, especially regarding the safety of foreign trade personnel who came to watch the rocket launch. After all, since it was made public, many people would come to watch Tiangong Technology's rocket launch every time.

Therefore, Wang Bin plans to build a viewing platform made of special glass at a distance of 1.5 kilometers from the rocket, specially for those who come to watch the rocket launch. With this viewing platform made of special glass, even There is a problem with the rocket, and the strength of special glass is enough to protect the safety of the people inside.

"Mr. Wang! The Tiangong-4 rocket this time is the largest rocket manufactured by Tiangong Aerospace since its establishment, and the total tonnage of this rocket has reached more than 800 tons. It has reached or exceeded the total tonnage of rockets of most countries in the world.

If our rocket is successfully launched this time, it will definitely improve our Tiangong Technology's voice in aerospace, and it will also greatly promote our country's aerospace industry.

However, although our rocket has reached the level of a real heavy-duty rocket in terms of total tonnage, in terms of carrying capacity, it still has a considerable gap with the carrying capacity of the official rocket of the same tonnage. After all, the official rocket of the same tonnage The rockets in China have a carrying capacity of more than 20 tons, but our rocket has a maximum carrying capacity of only 15 tons. "In the control room, the person in charge of the rocket's development and launch said.

"Indeed! The carrying capacity of our rocket is quite different from the official rocket of the same tonnage. There is a gap of more than five tons. After all, our rocket needs to be recycled at all levels, which leads to The weight of each stage of our rocket exceeds that of rockets of the same type. After all, it needs to be recycled, which means that each stage of the rocket must save a certain amount of fuel so that it can be used when it is recycled. The carrying capacity makes the rocket's carrying capacity only fifteen tons.

But even so, as long as we can successfully recover the rocket, the carrying capacity I decided to pay is definitely worth it. "Wang Bin said.
