Chapter 70: Ultra-long-term planning-building spacecraft

As for the harvest of various metals, Lei Tiantang is too lazy to count the specific quality of them. Anyway, he doesn’t know how long it will take for the harvest to be used up. He simply estimated the gold of 6 nines. There are probably more than 300,000 tons in one shot. How much of this gold can he use on the earth? It's not as useful as iron. At least iron can be used a lot when he builds his underground laboratory.
　　 With such a big harvest, Lei Tian Tang finally has a passion for work again. The universe is so big, I want to see it! And if you want to go to the waves in the universe, at least there must be a spacecraft, and it must be a super-high-tech superluminal spacecraft! Otherwise, if a conventional spacecraft does not have a super-light-speed engine, it can only travel at a speed lower than the speed of light. What if you fly faster?
In the vast space, there are countless stars. Among them, the nearest star to the sun is called Proxima Centauri. It is located in the constellation Centauri. Its scientific name is Alpha Centauri C, which is only 4.22 light years away from the sun, which is equivalent to 3,9923.3 billion kilometers. . If you use the fastest spacecraft now to travel to Proxima, it will take 170,000 years to go back and forth. It is conceivable that the universe is so large that Proxima is far away.
　　 By comparison like this, everyone should know the difficulty of surfing in the universe, right? Even if we drive an ordinary spacecraft to 0.99 times the speed of light, it will take more than 4 years to reach Proxima. That is the closest galaxy to the earth, let alone when the spacecraft can reach this speed?
Lei Tiantang still has a lot of thoughts on this point. He has no doubt that he can go to the universe to wave, because he can handle the most important materials for building a spacecraft, and there is no problem with any quality materials he wants. A spacecraft that can fly in the universe is a huge system engineering, but it doesn't have to have materials.
Therefore, Lei Tiantang set a small goal for his plan first, to build a spacecraft that can sail in the solar system. With the current technology, there is no problem if it develops and develops. Now it is restricting mankind to not use the solar system spacecraft. The main reason for the construction is the material problem. Without good materials, the rocket’s thrust cannot go up, and the massive spacecraft cannot be sent into space. Even if it comes to space safety, there is no guarantee. There are too many dangers in space. All kinds of radiation and space dust can threaten the safety of spacecraft.
And if you want to build a spacecraft that can take off directly from the earth, you have to do a lot, because humans have never done anything in this area, so everything must start from scratch, but Lei Tian Tang is still very If he is confident, he can solve the most critical material problem, and the rest is the design matter.
Of course, design and construction is also a big project. Each system of the spacecraft has only limited experience to learn from, and almost all have to start from scratch. For example, communication in the universe must now choose quantum communication, and quantum communication is still at the forefront of science. China is at the leading level in this field, but there is still a long way to go before it can be maturely applied on the spacecraft.
Another example is the life-sustaining system of a spacecraft. Although there is an example of the International Space Station, the International Space Station is regularly recharged. If the spacecraft required by Leitiantang has to travel for a long time in the solar system, the replenishment will be a big problem. Can't you still launch supply ships often? Therefore, the sustainable life support system on the spacecraft is very important, and green plants can also relieve the anxiety of astronauts in confined spaces for a long time.
There are also spacecraft engines. For a large-mass spacecraft to take off from the earth, of course, it needs a powerful engine, and there is almost no precedent for such an engine, so it must be designed and manufactured from scratch. This will be another one. big project.
There are also control systems, escape systems, etc. that almost have to be designed from scratch, but Lei Tiantang is not frightened by these problems. His life is already open, and now he can have a goal for him to struggle. But it's a good thing, otherwise, should we consider how to make money every day? He won’t be short of money now. Not to mention the value of the precious metals such as gold he owns, but the new material company he is currently focusing on. When the new laboratory equipment arrives, he will open up and help develop some new materials. , How much does it cost?
Of course, there is nothing wrong with being rich. It will definitely cost astronomical amounts of money to build a spacecraft, but money alone is not enough. The point is that sometimes it is useless for you to have more money, like the Leitian Tang plan to build spacecraft. Without the participation of the state, Lei Tiantang alone and his company would definitely not be able to do it.
Lei Tiantang considered this when he thought of this small goal. Without the participation of the country, many things could not be done. The simplest point is that the top talents are almost the treasures of the country~EbookFREE.me~ If you want to design a spaceship, you have to participate in these treasures. Otherwise, if you recruit some talents to cultivate and participate in the design, then this spaceship can be built without knowing the year of the monkey!
The key is that you must be able to do such a big project in a superpower like China, because he has the foundation of this industry and there is no shortage of talents. If you want to build a spacecraft in a country like India, Then just dream, they can't even make their own guns! Therefore, Lei Tiantang must obtain the support of the state.
It is definitely impossible for the country to agree to such a plan in the early stage. It is estimated that the country will not participate until the middle and later stages, because if an individual goes to the country and tells the country that I want to build a spacecraft, the country will take care of you. Money doesn't work, you have to prove that you can do this, and then seek help from the state. This is the way to do things, otherwise the slogans will be useless.
However, we still have to maintain contact with the country in the early stage, and Lei Tiantang has chosen the target for the early contact. His company is to carry out new material research, and he plans to be the first to develop after the laboratory equipment comes back. The new material is the invisible paint, which is the invisible paint used on high-end armaments such as invisible fighters. The current invisible paint is basically repainted all day after being used at most a few times, as is the case with the American F22.
There are still several F22s in his storage space. There are ready-made invisible paints on them for his reference. After he solves the problem of invisible paints that are not durable, his company will also become a key national military-industrial cooperation unit. When he later develops new materials and gradually cooperates with the country, it will be very convenient to go to the country to cooperate when he has prepared all the preliminary preparations for the spacecraft.
