Chen Xu locked the drawings in the safe and explained to Lao Ke: "You can read this drawing at will, but you must not copy any data on it, at most you can only remember it by heart." Pen "Fun" Pavilion www.biquge.info Now the international environment is very chaotic, there are a lot of mosquitoes and flies around, you must pay strict attention to confidentiality. ”

"Then you can rest assured, this factory is surrounded by guards with guns, which spy dares to run to steal drawings when he is full!" Lao Ke was overjoyed, rubbed his hands and said that he would not reveal the secret of the drawings.

With Chen Xu's approval, he planned to live in this factory for the next few months, wholeheartedly understanding all the formulas on the design drawings and experiencing von Braun's genius design ideas.

The seven departments are temporarily crammed into the same plant, and Chen Xu can easily shuttle between departments to inspect the progress. Although they were all grass platform teams, the situation of the project team with two bombs and one satellite was even worse than this, and they were completely relying on local methods to carry out research.

"Do you have any eyebrows and ideas about nuclear-powered rockets?" Chen Xu suddenly appeared behind the table in a circle of the nuclear-powered spacecraft team, suddenly stuck his head in, and asked curiously

"The idea is that we have a disagreement about whether the rocket should be implosed or implosed as a propulsion method. And according to our calculations, if you simply push a 50,000-ton behemoth into the sky, there is no problem in theory, but the problem is to propel such a large spacecraft, most of the weight is wasted on the weight of the hull and the fuel it carries, after all, the fuel required for such a long journey to Mars will not be less than 30,000 tons, plus the weight of the 10,000-ton spacecraft.

The actual payload may be less than 10,000 tons, which means that the 40,000 tons of payload will be eaten by the spacecraft itself. A research institute took out a conceptual map of a nuclear-powered spaceship, and also used an aircraft carrier of the US imperialists as a comparison, showing that the size of this spacecraft is almost the same as that of an aircraft carrier, but the meaning of his words shows that the spacecraft is definitely not as capable of holding 50,000 tons as imagined.

"What's the difference between implosion and implosion?" Chen Xu asked rhetorically.

"The implosion is to make a solid disc under the rocket as a shock absorption plate and a propulsion plate, and then continuously throw a small-yield nuclear bomb under the disk, when the nuclear explosion will produce gas impact at the bottom of the disk, and then move the rocket to fly. It's so simple and easy that even we can easily design it. But the problem is that the energy utilization rate of this propulsion method is very low, and most of the energy generated by the nuclear explosion is dispersed into the air and wasted, but even so, the efficiency of the nuclear-powered engine is still dozens of times that of the chemical award. An old researcher with white hair walked up to Chen Xu's side, pointed to the concept drawings of the implosive nuclear-powered spacecraft and slowly explained.

After seeing Chen Xu digest it, he pointed to another conceptual map and said: "If you use the implosion propulsion method, it is to set up an oval combustion chamber with a nozzle at the tail of the rocket, so that the nuclear bomb explodes in the combustion chamber and then the high-temperature and high-pressure gas generated is sprayed out of the nozzle, so that all the explosive energy of the nuclear bomb is bound to the combustion chamber, and most of it becomes thrust, and the energy utilization rate is significantly improved." But the problem is that the thrust generated by the nuclear explosion will instantly accelerate the rocket to the extreme, and the astronauts inside will die in an instant due to gravitational overload. Of course, this is not the most important thing, the key is that we do not have such a powerful material to make the combustion chamber, such a material has to withstand the impact of a nuclear explosion, but also to withstand the high temperature and high pressure generated after the explosion, we really can't imagine how to meet the requirements. ”

"On the issue of the load being taken up by fuel and the ship's own weight, we can choose to take off unmanned, and after the spacecraft is turned into a space station in Earth orbit, we can send astronauts on chemical rockets. Secondly, we don't need to think about how much fuel the spacecraft carries, we can make a separate external fuel tank, launch it into space separately and then dock with the spacecraft, which can solve the problem. ”

Chen Xu paused, and then continued: "Let's open up our minds, don't stubbornly think that everything is stuffed into the same spaceship. We can develop different spacecraft according to different functions, such as a living ship that is completely used by astronauts to house food and entertainment facilities, a fuel ship dedicated to storing energy, and an engineering ship that transports experimental and engineering equipment. Anyway, our nuclear-powered spacecraft are all the same shape, and they can launch seven or eight of them, and then connect them together like building blocks in low-earth orbit to turn them into a super-large space station. ”

"Oh my God! If so, then according to the weight of 50,000 tons per spacecraft, the combination of eight such spacecraft is a behemoth of 400,000 tons, this is no longer a space station but a space city, how much does it cost! The researchers couldn't help but exclaim, such an extravagant plan was like a fantasy for everyone, this was simply a truck to transport money and burn and play, everyone couldn't imagine how much money this plan would cost, and naturally there was no way to make such a crazy imagination.

"You don't care how much it costs, anyway, how crazy you come, anyway, remember that within a reasonable range, the bigger the space station, the better, it's better to really build a space city." Chen Xu encouraged everyone, don't be shackled by a little funding, rest assured to boldly open up your thinking, anyway, 80 billion US dollars will definitely not be burned.

Compared to the US imperialism that took $100 billion and turned into artillery shells in the Vietnam War, except for a bunch of soldiers with heavy casualties and a huge amount of money, the people of the US empire did not gain much.

It looks like a fool of yourself to build a 400,000-ton space station with $80 billion, but in the end, it can be seen and touched, allowing mankind to have the experience of building a city in space. Much more reliable than the Americans.

The researchers looked at each other, and saw the excitement in each other's eyes, everyone was born in a good era, and there will be no regrets in this life to be able to participate in such a grand space city plan.

"Regarding the way the ship is propulsed, I think implosion is indeed more reasonable, and I agree with this plan! As for the combustion chamber, we can use a miniaturized nuclear bomb to reduce the power of the explosion, and at the same time develop a stronger composite material to use as a bulkhead. I believe that with your wisdom you will eventually be able to solve this problem. Chen Xu knew that these researchers could not make their own decisions, and they needed him, the president, to make decisions, and then they would study in this direction.

Nuclear-powered spacecraft is originally conceived, no matter what kind of propulsion scheme has its difficulties, simply pick the best performance to study, as long as you spend enough money and have enough experiments, you will definitely succeed in the end, it is nothing more than a matter of how much money is spent.

"President, according to the Comprehensive Nuclear-Test-Ban Treaty, the whole world can no longer conduct nuclear weapons tests on the earth, and it seems that we are violating international law by engaging in this nuclear-powered spacecraft!" A female researcher asked softly, and the room was full of men, and the female researcher in a white coat stood out, so that Chen Xu couldn't help but look at it twice.

However, although this woman's voice is good, she has a big pie face and squinted eyes, and she is a typical engineering girl who can't get married. But Chen Xu is not the kind of leader who selects talents by looking at his face, so he didn't think there was anything wrong with this woman's appearance, but decided to answer her question well.

China's proposition is that if it wants to ban nuclear weapons, it must resolutely and completely destroy all nuclear weapons, and the United States and the Soviet Union have already tested enough nuclear weapons, and only now have they promulgated a treaty to restrict others from conducting experiments, so China has not signed this treaty at all. Since we do not recognize the legitimacy of this treaty, no matter how we conduct a nuclear test, the United Nations will not be able to control us. Chen Xu popularized science to everyone, this matter must be made clear, otherwise it will have an extremely negative impact on everyone's research, after all, international law is very fucked, if this kind of large-scale scientific project really violates international law, it will still cause great harm to the country, and no one wants to bear this pot.

The Comprehensive Nuclear-Test-Ban Treaty was proposed in 1963 by India's Ahsan, which was affirmed by the United States and the Soviet Union at that time, and set off an anti-nuclear wave in the United Nations.

But at that time, China's atomic bomb had not yet begun to be tested, and it was impossible to sign it at all. It was not until 1996 that China completely mastered the technology of miniaturizing nuclear weapons that it formally signed this treaty, after all, the proliferation of nuclear weapons is also very harmful to the flower planters, and since the Americans are willing to take the lead to become the world's policeman, of course we are happy to reap the benefits of nuclear non-proliferation.

However, signing is one thing, but our people's congress did not pass the review, indicating that this contract still cannot take effect in China, which means that this treaty still has no binding force on flower growers in the international community.

In fact, not only ourselves, but also the United States only signed it, and Congress did not approve it. The same is true in Russia, where the State Duma parliament did not agree. The most humble thing is that as the sponsor of the bill, Ah San himself only signed it, and the parliament did not recognize this treaty.

What the flower planter now means is that the Eagle Sauce Congress approved us before agreeing to approve it, and the United States will take the lead in passing it anyway.

But Eagle Sauce said that as long as the big hairy bear signed, I would sign it immediately.

And Mao Xiong said that as long as the flowers are planted, I will never hesitate......

Then the three major nuclear powers in the world did not ratify the contract. The Nuclear Non-Proliferation Treaty will never have any effect on the nuclear powers, but it will be very binding on the non-nuclear countries, and any country that dares to conduct a nuclear test after the launch of the treaty will immediately be punished by the five hooligans of the United Nations, and the dissolution of the government is a trivial matter.

China has not signed the Nuclear Non-Proliferation Treaty, which means that there is no legal obstacle for Chen Xu to develop nuclear-powered rockets, although the United States and the Soviet Union will talk about this matter, but this is a space science experiment, for the dream of all mankind to get out of the blue star, and it will be morally supported by all mankind, and the opposition of the United States and the Soviet Union will not affect Chen Xu's plan at all, so he can rest assured that he can study his own nuclear-powered spacecraft.
