Chapter 1780

"President Qin, it's really an eye opener for us to visit here today." swangeland said: "you are already in the forefront of the world in terms of launch vehicles. We are very confident in your commercial launch of rockets, and we will also sign a seat reservation agreement with you."

Last time they came, they had this intention. After returning, they conducted repeated discussion and research. Now, they learned the high level of Han rockets and finally made this determination.

Han countries have this ability, and their launch price is cheap. Why not choose Han people?

At this time, it was the end of the investigation. At the banquet, everyone was jubilant, and the eagle customers were quite satisfied.

"Yes, we are also very confident, and I can show you our long-term plan," Qin Guan said.

Now, Eagle country and bear country are engaged in a space race. How can Han country not participate? Of course, the true and false projects of the state of Han should also show their plans in space. Let them know that the future development of the state of Han is definitely not bad.

As soon as Qin Guan said this, everyone became quiet. The banquet venue was set in a large box. Now, the lights of the box dimmed, and then a slide was printed in front.

"Now, our long march series rockets are under planning." this slide is not in the form of an ordinary slide. It is actually directly connected to the computer. The above breakthroughs are also in the computer!

Is that too advanced?

The slide projector was invented by the Han people. Yes, our shadow play is the original slide projector, which is definitely the earliest. After a long development, it began to use electric light source and became a modern slide projector. However, it is absolutely the latest as a peripheral of the computer.

After everyone's shock, they began to look at the big screen above.

Now, only long March II and Long March III, but a new series of rockets have been developed and formed a big family!

One of them is the heavy rocket, the long march v. this kind of rocket is almost the same order of magnitude as the Saturn V rocket. Its near earth carrying capacity is at least 50 tons, right? Definitely for the space station!

It seems that the state of Han is bent on manned spaceflight!

Of course, there are also small solid rockets, which are said to be capable of launching at any time and are flexible.

The first page introduces the past, and the second page is manned spaceflight. The manned spaceflight of the Han people seems to follow the path of the bear country, using the way of spacecraft, and then engage in the space station. When the slide of the Han people's space station came out, everyone shouted excitedly. It's so beautiful!

The space station is a core module in the middle. There are six interfaces outward. These six interfaces can be extended to six sides. In this way, it is a unique and beautiful shape. It looks quite spectacular!

"Why don't you develop the space shuttle?" someone asked uncontrollably.

"We believe that the current technology can not be reached, and the space shuttle has many technical defects." Qin Guan said: "if you want to do it, you have to wait for the continuous progress of technology, that is, after the third phase of our space technology project is realized."

The first phase is these rockets, the second phase is manned spaceflight, and the third phase is what?

Then the slide turned down. When everyone saw it, everyone was stunned.

This is more evil than eagle's Star Wars plan. What do they see?

Nuclear rocket engine!

"The performance of chemical rockets has been developed to the extreme. If you want to make peaceful use of space, you need a new generation of rocket power system. We think nuclear powered rockets are the most suitable."

Aren't you kidding?

Nuclear power systems can be used on aircraft carriers and submarines. This is because nuclear power provides heat and then turns into electric energy. Space rockets need thrust, but not propeller thrust. What are they going to do?

Yingguo and xiongguo have also tried. One is to build a nuclear explosion engine, constantly detonate the nuclear bomb in the back, and push their rocket to accelerate in a barbaric way. The other is to use the heat generated by the nuclear reactor to heat the liquid hydrogen from the fuel tank to a temperature of nearly 10000 degrees Celsius and then eject it to push the rocket with a strong air flow.

This is similar to chemical rockets, but it can be improved because there is no oxygen tank, and the efficiency is at least twice that of today.

However, these are all planned. No actual rockets have been developed. Now, Han people are also engaged in this kind of project? How much will it cost?

When the next slide comes out, everyone is looking at the schematic diagram in surprise. It's very strange.

"Well, what is it?" someone asked.

"We know that using nuclear power, the biggest problem is not nuclear radiation at all, nor is it controllable. The most important problem is that there is no high-temperature resistant container. If nuclear powered Rockets want to release tens of thousands of degrees of high temperature, what material can have such endurance?"

Controlled nuclear fusion is also limited by this.

If this problem is not solved, the nuclear powered rocket is a castle in the air and a thing taken for granted.

Now, the introduction of Han is a brand-new concept.

"Therefore, our system perfectly avoids this problem," Qin Guan said "We call this electric rocket more appropriate. We use the heat generated by nuclear energy to ionize liquid hydrogen and other propellants to the plasma state. Then, we use the electric energy generated by nuclear reactors to accelerate them in the electric field to close to the speed of light, so we can generate huge thrust. Moreover, this thing will not be very hot, and our existing materials can be solved."

What is this, an electric rocket?

How can there be so many wonderful ideas in the Chinese brain!

In fact, there are also many problems. The electric energy required to accelerate particles to the speed of light is absolutely astronomical. It is not easy for this nuclear reactor to ionize liquid hydrogen into ionic state, but this does not prevent Qin Guan from fooling here. "When this technology matures, we will develop special aerospace vehicles, which can take off and land in the atmosphere. The engine is only placed at the tail, and the fuel tank is stored in the two interlayer inside and outside our aircraft. In this way, most of the space inside the aircraft is used for riding, which is called the real space shuttle."

No one spoke and everyone was shocked. Qin Guan laughed in his heart. He didn't know that Xiong Guo and Eagle Congress would not take the bait and invest a lot of money to study these things. If Eagle country was dragged down by this, it would be interesting.
