Chapter 297 (1/2)
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.
