Chapter 1645

Qin Guan knows, because many materials have been declassified in later generations. Yes, Xiong Guo and Ying Guo really thought about nuclear powered rockets.

The first is the eagle country. The idea of the eagle country is the most violent. It is more like the practice of the bear country. They use nuclear bomb explosion to promote.

Yes, nuclear explosion is the first power mastered by mankind. It is not an engine, but pulses again and again.

According to the eagle people's idea, the spacecraft carries a large number of low equivalent atomic bombs, which are left behind one by one, and then detonated. A propulsion disk is installed behind the spacecraft to absorb the explosion shock wave and push the spacecraft forward.

If this project can be implemented, it can be imagined that the astronauts of Eagle country are like sitting in a rocking car, shaking and shaking constantly.

This plan is very abnormal. In order to reach Mars, they need to carry 2000 atomic bombs. Of course, this method is also quite advanced. Under the condition of the same weight as the current rocket, it has realized the loading capacity of 150 people and thousands of tons, so that they can live comfortably after they arrive on Mars.

However, constantly detonating nuclear bombs in the atmosphere must be quite destructive to the surrounding environment. Later, bear and Eagle signed the atmospheric nuclear test ban treaty, and the plan was finally terminated.

Using nuclear bombs to propel is itself an imaginative operation.

In contrast, Xiong Guo's plan is more feasible. It is also like a type of reactor. Using the huge heat of the reactor, the propellant carried by the spacecraft is heated, expanded, and then ejected backward to push the spacecraft forward.

This method is also the most feasible. However, like today's chemical rockets, it also needs huge propellant, so the efficiency is not high.

When the space station is finished, what's the next plan? Nuclear rocket?

Qin Guan knows, I'm afraid he can't see it. Can he struggle for decades? During this period of struggle, it is impossible to see this technology mature, which is more like a science fiction statement.

So, what should I do now? Should we deny it?

In Qin Guan's heart, there is a voice saying that as a leader of science and technology, we must look forward, look forward!

There is no end to the road of science. Only by looking forward and forward-looking can the country really develop and become strong. Look, how many years of history does modern science and technology have? The development of science and technology is accelerating. We can't see it now. Maybe technology will break through in a very short time?

Besides, I have my own journey. My arrival here has greatly promoted the country's scientific and technological development. If it weren't for me, the J-10 would not be finalized and tested until the end of this century.

Thinking of this, Qin Guan finally resisted his disapproval and changed his attitude. If he wanted to support it, he should set a direction.

Nuclear explosion type? Of course not. Nuclear reactor heating? Of course not. There is only one kind of real hope, that is, nuclear fusion!

"This nuclear powered rocket is not what our aerospace engineers want to start at the moment," Qin Guan said. "This is the research topic of our nuclear power engineers, especially the engineers of controllable nuclear fusion. We can enter the real research only after the breakthrough of controllable nuclear fusion."

Controlled nuclear fusion is a new research direction. Now, there is almost no breakthrough.

The release of nuclear energy requires mass loss. There are only two ways of mass loss, heavy nuclear fission and light nuclear fusion. Among them, fission has been widely used, both nuclear bombs and nuclear reactors. However, light nuclear fusion is different.

It needs to press two atomic nuclei into one atomic nucleus and overcome the huge Coulomb repulsion between atomic nuclei. Now the only way is to detonate with an atomic bomb and heat it to a high enough temperature to produce a fusion reaction. Such a reaction process is doomed to be uncontrollable.

Only when nuclear energy can be controlled and released smoothly can it be used by mankind, not as a weapon.

But this is not easy. Even in 2020 when Qin Guan came here, there is no practical application of this technology, but it is obvious that once controllable nuclear fusion is realized, it will bring about a complete change in the energy system.

The fuel needed for nuclear fusion widely exists in the sea. Nuclear fusion is reliable. Once it breaks down, fusion will stop immediately. It is absolutely not as dangerous as the current nuclear reactor. Therefore, it is the safest and most efficient.

Once it is mature, all conventional energy sources such as oil and coal stand aside. As long as this nuclear fusion is enough to maintain the needs of all human beings on the earth, it will not be exhausted for thousands of years.

Mankind will no longer worry about energy.

This is not science fiction, because now, some nuclear physics engineers have begun to study nuclear fusion reactions and how to release the energy of nuclear fusion smoothly.

This is also one of the national basic research.

We engineering experts in aerospace don't have to think about those plans against the sky. Let's wait quietly for the breakthrough of nuclear fusion technology. If we can make a breakthrough, we can start in aerospace. If we can't make a breakthrough, we can continue to start with chemical rockets.

"President Qin, do you mean that nuclear fusion is the only way for aerospace applications?" asked Ren.

Qin Guan nodded: "Yes, so for the time being, we'd better not worry about this new generation of engine. We'd better do a good job of the Long March 5 in front of us. This is our key project in the future. In addition, we should continue to follow up the commercial satellite launch project with SVIA and strive to launch this first shot. By the way, we can invite them to visit our factory." Our rocket factory is still confidential. In order to convince customers, take them to see how advanced our rocket manufacturing process is and dispel their concerns.

This commercial launch has been our own project in history. We can't let this project go yellow. This is also a key project in the future. After this good start, we can contract more projects.

The third day's meeting mainly discussed the networking and commercial application of Beidou satellite, which is also a major event in the aerospace system. Now, the project has entered the most critical period. The huge initial investment is a stumbling block, and these are not problems in Qin Guan's eyes.

The meeting of the space system came to an end slowly. Qin Guan's mission here was basically over. At the same time, in 1984, the curtain came to an end slowly.

In this year, China also made a lot of progress, especially in aviation. This air show made China go to the world.
