Chapter 297

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

In fact, for this rocket launch, not only the R & D and design personnel of the rocket through science and technology, but also the official testing team. After all, when the rocket is completed and delivered to the launch pad here, it is only a few days away from the rocket launch.

Therefore, when the rocket arrived and stood up, the rocket R & D team of Tiangong technology and the staff on the official launch pad immediately began to test the rocket, and they basically didn't rest much in recent days, even at night.

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

Then, after chatting with Qin, Wang Bin entered the rocket launch site, found Jia Jie and others who were carrying out the final test of the rocket, and asked Jia Jie, "Jia Jie, what's the situation, whether the rocket is normal, and whether it can be launched on time?"

"Mr. Wang! So far, we haven't found any major problems in the rocket testing, but we have detected some problems in the details. However, these problems in the details have little impact on the overall rocket. Moreover, we have also dealt with these problems in the details, so there is no problem in launching on time!" Jia Jie said.

"That's good! But you should pay attention to the details. After all, this is a rocket. If there is an accident during launch, the loss will be great! Apart from others, the price of this rocket alone is as high as hundreds of millions of yuan. If the official deep space communication satellite is added, the price will at least double.

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

In the world, many rocket launching accidents are caused by details, "Wang Bin nodded and said.

"Good president Wang! In terms of details, we will pay more attention in the future and strive for no problems after each rocket is designed and manufactured!" Jia Jie said.

After listening, Wang Bin nodded and didn't speak, because he was very clear that the manufacturing of rockets could not be 100% perfect. After all, how many parts a rocket is composed of, and so many parts can't be 100% perfect.

Of course, because Wang Bin's rocket of Tiangong technology is only a hydrogen and oxygen rocket, it is much simpler in terms of technical difficulty and complexity, and the probability of natural failure is much lower.

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

Multistage rockets are composed of several stages, and each stage has its own independent engine and fuel. Naturally, the purpose of this is to improve the carrying capacity, flight speed and flight ability of the rocket.

During the flight of a multi-stage rocket, the engine at the tail end is the first to start, so generally, the thrust of the engine at the tail end is also the largest, and many times, there is not only one engine at the tail end, but multiple rocket engines working at the same time.

When the fuel of the last stage rocket runs out, it will be separated through the separator, and the upper stage rocket starts to work. In this way, it can not only improve the flight performance of the rocket, but also reduce the overall weight of the rocket.

When the rocket fuel of the upper stage is exhausted again, the rocket will automatically abandon this stage. After this stage is abandoned one by one, it will finally put the transported spacecraft into orbit.

In fact, the working principle of the bundled rocket is similar to that of the multistage rocket. When the fuel of the outermost rocket is exhausted, it will be thrown away until the core stage and finally put the spacecraft into orbit. Therefore, in fact, the bundled rocket is also a kind of multistage rocket, or parallel rocket is more appropriate.

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

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

However, in fact, the Aerospace Laboratory of Tiangong technology still encountered many difficulties in developing multi-stage rockets. It did not know the design of rocket separators, the start-up of engines after rocket classification, the attitude control of rockets during separation, and how to make the separation section not collide with core stage rockets during separation, resulting in rocket out of control, etc, This series of problems need to be solved by the aerospace laboratory.

However, although there are many difficulties, Wang Bin is also very confident that these problems can be solved. Of course, it is very difficult to solve all these problems in a short time, at least within a year, if we only rely on the rocket R & D laboratory.

But fortunately, Wang Bin has a science and technology mall. He is going to buy some rocket technology, especially about heavy and super heavy rockets.

Therefore, Wang Bin is fully confident that Tiangong technology can manufacture multistage rockets within this year.

At the same time, according to Wang Bin's expectation, the carrying capacity of the second rocket of Tiangong technology must be at least one level higher than that of the first rocket, that is, the carrying capacity of the next rocket must be at least five tons, and must have a certain medium orbit carrying capacity.

Of course, Wang Bin's ambitious plan, as the R & D Laboratory of Tiangong science and technology rocket, is naturally very opposed. In their view, the requirements put forward by Wang Bin have gone too far. At one time, the carrying capacity has been increased from 0.5 tons to 5 tons, which is easy to pull eggs.

They believe that launch vehicles should be developed step by step. Now that they have successfully developed launch vehicles with a carrying capacity of 0.5 tons, they can then develop launch vehicles with a carrying capacity of about 1 ton or 1.5 tons, and then develop rockets with a class of three to five tons, and then slowly improve the carrying capacity.

However, in Wang Bin's view, such R & D speed is too slow. Wang Bin can't wait. He can't wait. Tiangong technology can produce rockets with hundreds of tons of carrying capacity at once. In this way, Tiangong technology can immediately start building space stations and space exploration projects. In this way, it can also catch up with foreign private space companies.

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

As time went on, when Wang Bin returned to the rocket launch control room again, it was less than ten minutes before the first launch of Tiangong technology. At the same time, with the gradual approach of time, there was a trace of tension on the faces of Wang Bin and Tiangong technology's rocket design and R & D personnel, although they were comforted by the official rocket launchers, After all, this is the first launch of their first rocket of Tiangong technology.

On the contrary, the official launch personnel, due to their many rocket launch experience and even many rocket launch failures, did not have a trace of tension on their faces at this time, but all seriously operated the equipment and checked the monitoring data.

Finally, when it was 8:10, after the countdown to the launch of the rocket was read, the various instruments and hydrogen and oxygen fuel supply pipes on the rocket began to fall off, and the rocket began to ignite.

As a huge fire erupted from the bottom of the rocket, all the cooling devices on the rocket launch pad began to work, and the rocket began to rise slowly and steadily, and the speed also increased with the increase of height.

At the same time, the people who came to watch the rocket launch on the shore not far from the launch pad also took out their mobile phones or professional cameras and began to record this moment. Among these people, there are many foreigners with different skin colors from China.

And unlike the people in China, some of these people obviously have a trace of worry on their faces. In the hearts of many of them, in fact, their mood at this time is very contradictory. If they stand from the perspective of all mankind, they also very much hope that the rocket launch will succeed, but if they stand from the perspective of their national interests, They absolutely don't want this launch to succeed.

After all, once the launch is successful, it means that a private aerospace company with strong technical ability has emerged in China for so long, and this company will compete with their country's x aerospace company in aerospace business. Most importantly, they have no good way to take this private contract company in China!

Although the hearts of these people are very complex, the rocket launch will not stop because of their ideas. The rocket continues to live, and the speed is also improving. Soon, the rocket rises by thousands of meters. At the same time, on the ground, you can only see the fire emitted by the tail of the rocket when it flies.

Of course, at this time, although the rocket has risen to an altitude of more than 1000 meters, Wang Bin, the rocket design and R & D personnel of Tiangong technology, and the official launch personnel do not relax. After all, the rocket just took off successfully. They all know that, Only when the rocket completely puts the spacecraft into the predetermined orbit can it be regarded as a complete success.
