Chapter 553 Press Conference on Launching Satellites (Part I)

Although Zhao Chen does not have a factory to build satellites in his hands now, Zhao Chen has a system that can be exchanged directly, in fact, don't think that rockets seem to be high-tech products, but strictly speaking, the technical level of the current launch vehicle is actually very ordinary, and it is not even as high as the technical level of some fighters.

Because unless you can invent epoch-making technology, otherwise, its performance technology is the same, and there is no way to improve it by leaps and bounds, because whether it is solid fuel or liquid fuel, the rocket's engine and fuel technology limit its carrying capacity.

Of course, now the uranium engine technology developed by Zhao Chen is naturally not among them, the uranium engine technology is from Elysium space, and then the engine developed by Su Jie using modern technology to simulate the construction, this engine technology can be said to have reached the standard of preliminary long-range astronautics.

After the launch vehicle is installed, it can already be separated from the category of conventional launch vehicles, or in other words, if it is used to build launch vehicles, it is actually a bit overkill, because of the structural problems of the launch vehicle, which leads to it can only be a disposable object, but the uranium engine is too wasteful if it is used for one-time use.

But at this time, it is too shocking to directly expose a spaceship that can be reused, and it can take off by itself, and does not need a launch vehicle.

For example, the Long March 7 launch vehicle, which is now about 53 meters in length, but the total mass of the cargo that can be transported is only more than 14 tons.

Even if this mass is already considered to be the international leading level, but 14 tons, the volume of a satellite or spacecraft that can be transported is still too small.

Therefore, this time the simple version of the uranium engine was directly used, which reduced the quality of the engine materials to ensure that after the thruster was abandoned, it could be burned directly through atmospheric combustion, and even some special combustion additives were added to the engine.

Secondly, because the fuel volume of the engine is greatly reduced, the volume of objects that can be carried naturally rises sharply, and while keeping the volume of the Long March 7 launch vehicle unchanged, its carrying capacity can be directly increased to a terrifying 500 tons!

You must know that the previous Long March 7 launch vehicle has a total mass of about 597 tons and 600 tons. However, the objects that can be transported are only a dozen tons, and that is because the vast majority of the entire rocket body is liquid fuel.

But now it's different, because of the uranium engine, the weight of its fuel plus shell has been reduced to less than 100 tons, and the rest can be used to transport supplies.

In fact, although the entire appearance has not changed, in fact, the Long March 7 has changed.

Because the previous Long March 7 was only sent into space in the most cutting-edge part, that is, the carrier part, whether it was a spacecraft or a satellite, only the top part, and the rest were rocket bodies and directly discarded.

But now, although the entire Long March 7 still has boosters and first-stage thrusters, the first-stage thrusters are greatly shortened, and the second-stage thrusters are actually part of the spaceship, and the second-stage thrusters will not separate, but go directly into space, and the interior of the second-stage thrusters is no longer fuel, but the ability to carry materials inside.

In other words, the second stage thruster used to be stuffed with liquid fuel, but now it is stuffed with materials that can be used in space.

After getting this rocket out, Zhao Chen directly transmitted the data to the owl, and the owl didn't even look at the data when he got it, and directly passed it to the top.

When they got it, they were immediately speechless, but after thinking about it, they made up their minds directly, the enemy has bullied their heads, what else are they hiding from? In the words of a TV series, what is needed now is the spirit of the bright sword!

Now that he has made up his mind, in fact, the uranium engine technology that Zhao Chen used to exchange before has already begun to be manufactured in China, and it is directly built with the highest level, and now that it is built at a low level, it is even simpler.

Therefore, make up your mind, then directly start replacing the power system of the original three Long March 7 launch vehicles.

This time will take about two weeks.

And at this time, it's time to build momentum.

So at a time when the THAAD system was in full swing and the major domestic media and South Korea were reporting on the THAAD system in a big way, China suddenly held a press conference.

After all, the Chinese Foreign Ministry has been making serious protests against the United States because of the THAAD system, but protests are protests, which is actually useless, after all, it is impossible for the United States not to implement my policy because of your protests in China.

But in the past, it was the Ministry of Foreign Affairs, but this time it was convened by the Chinese government, and there are still some differences between the two levels.

But when all the reporters arrived at their destination, they found out that it was not convened by the Chinese government, but by the Chinese Academy of Sciences...... What the hell is this going on with the organizers of the press conference? But these reporters have repeatedly confirmed that this is indeed the venue, and that they have received the invitation to this press conference.

Since they came, it was natural that everyone went in, because the level of this press conference was relatively high, so there were a lot of media invited, and when they arrived at the scene, these media reporters immediately felt a burst of energy, everyone is a reporter, and naturally knows that sometimes the number of media is also related to the importance of this press conference.

And this press conference is obviously heavyweight, but looking at the title of this press conference, all the reporters are a little unsure: the press conference of the Chinese Academy of Sciences, that is, the Long March 7 satellite launch plan? What the hell is this?

If in the past, satellite launches, and even CCTV and television would hold special news reports, but now, when satellite launches have become the norm in China, you will find that in fact, sometimes you have not seen the reports, and the satellites have already been launched.

After all, in the past, it was estimated that it would be launched once a year, or even once in a few years, but now it is launched more than ten or twenty times a year, which is naturally not such an important thing, everyone is used to it, and you can still take it as news what you often see?

It's just that why there is a press conference for the launch of this satellite, although I don't know why, but these reporters are not stupid, which means that this press conference is definitely not an ordinary press conference.

The press conference was soon held as scheduled, and when the staff of the Academy of Sciences directly announced the start of the press conference, they immediately announced the news that shocked all the reporters.

"After more than ten years of hard research, China has finally made a major breakthrough in rocket engines. "When the spokesman came up, he threw a big bomb, and all the reporters were shocked.

All the reporters shook their heads with a cold war, because everyone knew that to a certain extent, the rocket engine was actually common to strategic ballistic missiles!

There has been a major breakthrough in rocket engines, which means that both long-range ballistic missiles and strategic ballistic missiles have made major breakthroughs!

When I went to think of this, all the reporters gasped, could it be that the Chinese government is saying, "You have deployed the THAAD system, right?" Then I'll tell you that I have more awesome weapons.

But when I thought of this, all the reporters immediately became excited, "Damn, I like to watch this, hello everyone, what do I have to watch? Readers don't like to watch it! The audience doesn't like to watch it either! Now they just come up and do things! This is the big thing!

Many clever media in China even directly sent a text message to attract the audience's attention first.

"Production of our latest improved version of the Long March 7 has begun, with an intensive launch expected in two weeks. The spokesman continued.

All the reporters immediately got excited, oh my, intensive launch? How dense is this?

"We will launch eight Long March 7 launch vehicles at the same time at the four major satellite launch centers across the country, and each satellite center will launch two launch vehicles, which will be completed in one day. The spokesman continued.

At this moment, everyone was in an uproar, because everyone knew that except for the Long March 11 launched by China's emergency satellite, the other Long March series carrier rockets are liquid-fueled, because the thrust of liquid fuel is large, and the weight of the objects that can be transported is naturally large.

However, the speed of liquid fuel refueling is slow, and it takes a whole day to refuel alone, and it is naturally impossible to launch quickly.

The Long March 11 is a solid-fuel launch vehicle, although the delivery of things is small, but it can be prepared within a day, which is mainly the installation of satellites, etc., and the preparation work in the launch site does not exceed 1 hour, that is, in fact, the Long March 11 is more like a ballistic missile.

But now, the spokesman is talking about the Long March 7, but it has to launch two in one day, which is unprecedented.

"In the case of the new rocket engine engine, we use special dyes that can reduce the fuel requirements of the Long March 7 launch vehicle, and the mass of the object that can be directly generated by each Long March 7 launch vehicle will reach between 200 and 260 tons!" said the spokesman.

When he said this number, even the spokesman himself trembled a little, because he himself is an aerospace worker, and of course he understands how terrifying this figure is.

Nima, think about it, although the previous high-thrust launch vehicles also exceeded 100 tons, but that was a perversion of the Cold War period, and the take-off weight reached a terrifying 3,000 tons, 3,000 tons can send 100 tons, you say that you have a Long March 7 rocket with a total mass of more than 600 tons, you want to send close to 300 tons of materials? What kind of rocket are you? This energy efficiency ratio is not too high!
