When Wang Bin and the others came to the South China Sea Launch Center, Mr. Qin and others had already been waiting for Wang Bin's arrival. Seeing Wang Bin's arrival, Mr. Qin immediately stepped forward and said to Wang Bin: "Mr. Wang, you are finally here. Now the rocket is starting the final inspection. If everything goes well, the rocket will launch on time at 8:10."

In fact, for this rocket launch, not only the R\u0026D and design personnel of scientific and technological rockets worked very hard, but also the official testing team. After all, after the rocket was manufactured and arrived at the launch pad here, the The launch is only a few days away.

So when the rocket arrived and was erected, Tiangong Technology's rocket research and development team and the staff on the official launch pad immediately started testing the rocket, and they basically didn't have much rest in the past few days Yes, even at night.

That's why we can complete all the tests before today's launch.

Then Wang Bin chatted with Mr. Qin for a few words, and then entered the rocket launch site, found Jia Jie and others who were conducting the final inspection of the rocket, and asked Jia Jie: "Jia Jie, how is the situation? Is the rocket healthy, is it going to launch on time?"

"Mr. Wang! So far, we have not found any major problems in the inspection of the rocket, but we have detected some problems in the details, but these detailed problems have little impact on the rocket as a whole. , And, we have also dealt with these details, so there is no problem launching on time!" Jia Jie said.

"That's good! But even in terms of details, you have to pay attention. After all, this is a rocket. If there is an accident during the launch, the loss will be terrible! Not to mention other things, just the manufacture of this rocket, Its price is as high as hundreds of millions of yuan. If the official deep space communication satellite is added, its price will at least double.

So when checking, you must pay more attention to those details, after all, details determine success or failure.

Internationally, how many rocket launch accidents are caused by details. "Wang Bin nodded and said.

"Good Mr. Wang! In terms of details, we will definitely pay more attention in the future, and strive to ensure that each rocket will not have any problems after it is designed and manufactured!" Jia Jie said.

After Wang Bin listened, he nodded and did not speak, because he knew very well that it is impossible to achieve 100% perfection in the manufacture of rockets. After all, how many parts does a rocket consist of? It is impossible for all parts to be 100% perfect.

Of course, since the rocket of Wang Bin and his Tiangong Technology is just a hydrogen-oxygen rocket, it is much simpler in terms of technical difficulty and complexity, and the probability of failure is much lower.

If it is a multi-stage bundled rocket, then the technical difficulty is called high.

A multi-stage rocket is composed of several stages, and each stage has its own independent engine and fuel. The purpose of doing this is naturally to improve the rocket's carrying capacity, flight speed and flight capability of the rocket. .

During the flight of a multi-stage rocket, the engine at the end is naturally the first to start, so under normal circumstances, the engine at the end has the greatest thrust, and in many cases, the engine at the end is not just one , but with multiple rocket engines working at the same time.

When the fuel of the last-stage rocket is exhausted, it will be separated by the separator, and the upper-stage rocket will start working at the same time. In this way, not only the flight performance of the rocket can be improved, but the overall weight of the rocket can also be reduced.

And when the rocket fuel of the previous stage is exhausted again, the rocket will automatically abandon this stage, so that after throwing away one stage at a time,

Ultimately put the transported spacecraft into orbit.

The bundled rocket actually works in the same way as a multi-stage rocket. When the outermost rocket fuel is exhausted, it will be thrown away until the most core stage, and finally the spacecraft will be sent into orbit, so the actual The upper-bundle rocket is actually a kind of multi-stage rocket, or it is more appropriate to call it a parallel rocket.

Of course, in order to improve the rocket's carrying capacity and flight performance, modern medium-sized rockets will be designed in a multi-stage and bundled way. After all, this can effectively improve the rocket's carrying capacity.

Therefore, although Wang Bin and his Tiangong Technology developed only a single-stage rocket this time, their Tiangong Science and Technology Aerospace Laboratory has already started the research and development of multi-stage rockets. At the same time, Wang Bin Bin hopes to complete the research and development of the multi-stage rocket within this year.

However, in fact, the aerospace laboratory of Tiangong Science and Technology still encountered many difficulties in the development of multi-stage rockets. They did not know the design of the rocket separator, after the rocket was staged, the start of the engine, the attitude control of the rocket when it was separated, the rocket in the When separating, how can the separation section not collide with the core stage rocket, causing the rocket to lose control, etc. These series of problems need to be solved by the aerospace laboratory.

Although there are many difficulties, Wang Bin is also very confident that these problems can be solved. Of course, if he only relies on the Rocket R\u0026D Laboratory itself, he wants to solve all these problems in a short time. , is still very difficult, at least it is impossible to solve them all within a year.

But fortunately, Wang Bin has a technology mall, and he plans to go to the technology mall to buy some rocket technology, especially the technology of heavy and super heavy rockets.

Therefore, Wang Bin is completely confident that Tiangong Technology will be able to manufacture a multi-stage rocket within this year.

At the same time, in Wang Bin's expectation, the carrying capacity of the second rocket of Tiangong Science and Technology must be at least one level higher than that of the first rocket, that is to say, the carrying capacity of the next rocket The capacity must be able to reach at least five tons, and it must also have a certain medium-orbit carrying capacity.

Of course, as for Wang Bin's ambitious plan, the research and development laboratory of Tiangong Science and Technology rockets is naturally very opposed. In their view, Wang Bin's request is too big. All of a sudden, the carrying capacity has been increased from 0.5 tons to five tons, which is easy to talk about.

They believe that the launch vehicle should be developed step by step. Now that a launch vehicle with a carrying capacity of 0.5 tons has been successfully developed, then a launch vehicle with a carrying capacity of 1 ton or 1.5 tons can be developed next, and then three to five tons. Ton-class rockets, and then slowly increase the carrying capacity.

However, in Wang Bin's opinion, this kind of research and development speed is too slow. Wang Bin can't wait at all. Then you can start to build space stations and space exploration projects. In this way, you can also catch up with those private space companies abroad.

Of course, in Wang Bin's original plan, he also wanted to develop a larger rocket at once, such as a rocket with a carrying capacity of more than ten to twenty tons. This proposal directly attracted strong opposition from the R\u0026D personnel, and finally Cai changed it to A rocket with a carrying capacity of about five tons.

As time continued, when Wang Bin returned to the rocket launch control room again, it was less than ten minutes before the first launch of Tiangong Technology's rocket. The faces of these rocket design and development personnel of Tiangong Technology obviously removed a trace of nervousness. Although they were comforted by the official rocket launch personnel, they still felt nervous. After all, this was the first launch of their first rocket of Tiangong Technology.

On the contrary, the official launch personnel, because they have a lot of rocket launch experience, and even experienced many rocket launch failures, so at this time, there is no trace of tension on their faces, but all serious operations Check the equipment and check the monitoring data.

Finally, when the time came to 8:10, after the countdown to the rocket launch was finished, various instruments on the rocket and hydrogen and oxygen fuel supply pipelines began to fall off, and the rocket also started to ignite.

With the huge flame erupting from the bottom of the rocket, all the cooling devices on the rocket launch pad also started to work, and the rocket began to rise slowly and steadily, and the speed also increased with the increase in height.

At the same time, people who came to watch the rocket launch on the shore not far from the launch pad at this time also took out their mobile phones or professional cameras and began to record this moment. Among these people, there are many A foreigner whose skin color is different from that of Huaxia.

And unlike the people in Huaxia, some of these people obviously have a trace of worry on their faces. In the hearts of many of them, the mood at this time is actually very contradictory. If you look at it from the perspective of all mankind It can be seen that in their hearts, these people also very much hope that this rocket launch will be successful, but from the perspective of their national interests, they absolutely do not hope that this launch will be successful.

After all, once this launch is successful, it means that a private aerospace company with strong technical capabilities has appeared in China for a long time, and this company will compete with their country's x aerospace company in aerospace business. Most importantly, They also have no good way to deal with this Huaxia private contract company!

Although these people's hearts are very complicated, the rocket launch will not stop because of their thoughts. The rocket is still going up, and the speed is still increasing. On the ground, you can only see the flames ejected from the tail of the rocket when it is flying.

Of course, although the rocket has risen to an altitude of thousands of meters at this time, whether it is Wang Bin, the rocket design and development personnel of Tiangong Technology, or the official launch personnel, their faces are not relaxed at this time. At that time, the rocket just took off successfully. They all knew that only when the rocket completely sent the spacecraft into the predetermined orbit was it considered a complete success.
