An article by Star Navigator has caused an uproar in the world.

Big, big, big wave!

That article is written quite horizontally, and ordinary people look at it, good guys, it is separated by an explosion, it cannot be separated, and it collides after separation, balabala, it's too thrilling.

Relatively speaking, the more parts and steps, the number of problems will definitely be more, which is the same truth.

And for space enthusiasts who know something, they think a lot.

"This wave, this wave is the self-detonation of the Navigator Corporation?"

After all, the rocket of the Navigator company is also a multi-stage rocket, and even the super-heavy rocket under development is also a multi-stage rocket, and it is useless to criticize the multi-stage rocket at this time, stirring up people's fear of the multi-stage rocket, which does not do them any good.

This is not a self-detonation, what is it?

The appearance of multi-stage rockets naturally has its significance, it has many advantages, and it is also the guarantee that mankind has landed on the moon farthest.

First, it can throw away unwanted mass at the end of each stage of work, so as to obtain good acceleration performance during the flight of the rocket, gradually reaching a predetermined flight speed.

This is good to look at the Mammary Federation's Mark III rocket, which dragged two boosters with a total weight of 50 tons during the flight for 19 seconds, which not only wasted fuel, but also weakened the carrying capacity.

Second, the engines of the various stages of the multi-stage rocket work independently, and different engines can be designed according to the flight conditions of each stage, so that the engines are in the best working condition, so as to improve the flight performance of the rocket.

After all, the same engine does not perform the same engine at different altitudes and atmospheric pressures.

Now the better combination is the take-off stage of the rocket with liquid oxygen kerosene fuel, which is simple and crude, cheap and easy to use. When it is replaced by liquid hydrogen and liquid oxygen fuel at high altitude, the lean air and very small air pressure can give full play to its high specific impulse characteristics.

In this way, there will be a good balance between cost, efficacy, load and other aspects.

Otherwise, the whole kerosene is simple to make and cheap, but the load is miserable.

The load capacity of full hydrogen and oxygen is very good, but it is expensive and difficult to manufacture.

Although it is said that the aerospace industry "does not count the cost", in fact, the cost of aerospace is the most accurate calculation.

Third, the multi-stage rocket can flexibly choose the size and working time of each stage of thrust to adapt to the launch orbit, orbit measurement and the flight overload requirements of manned spacecraft.

These are all advantages of a multi-stage rocket, but these advantages have become its disadvantages to a certain extent.

For example, when the rocket separates and throws away the dead weight, it is likely that it will not be able to separate, or it may be separated early or delayed, or even hit other engines that have just started to work after separation.

There have been many times in history when either the booster hits the core stage or the first level hits the second stage, or the second level hits the third stage.

It's like a bumper car anyway.

And then the danger arises.

As soon as the number of stages increases, the structure becomes complex, and when the rocket is launched, it produces huge vibrations, and these vibrations can sometimes be fatal.

There are also many engines and a variety of them, which is also a problem.

Moreover, the structure of the rocket is very slender, the bending stiffness is poor, and it is not easy to achieve aerodynamic stability.

There are also a lot of complex problems, just as rockets are complex aggregates, all problems.

Professional aerospace companies and aerospace departments have similar ideas to enthusiasts, after all, they all know how to do it, and they don't understand the meaning of Navigator publishing this article.

If you want to say self-explosion, it will definitely not, and individuals may not check it for a while to say something exciting, but when an article is written, you need to check a bunch of information, and the time is calm enough, and even this article is not necessarily written by one person.

If an article is completed by a team and published through the company's internal review, it must have a deep meaning.

They don't want to ask, but someone will ask for them.

Media!

Star Navigator is not a small company, it is an internationally renowned private space company.

In terms of the company's rocket capacity, it can definitely rank among the top three in the current private space company launch vehicle rankings.

As for other private space companies that build rockets, either the big rocket is about to make its first flight, or the transportation capacity is only a few tons or even a few hundred kilograms, which is not enough to threaten the "Chu Voyage" rocket of the Navigator Company.

Even if you count all the institutions that have space rockets, it is still on the top rank.

At least the capacity of the "Chu Sai" rocket is stronger than the recently rumored Peacock Federation "Mark III" rocket.

A dozen tons is more than ten tons, and there is no suspense.

At this time, in the context of the development of the Navigator's own multi-stage super-heavy rocket, such an article was suddenly published, and the impact can be imagined.

All the media want to know what's going on here.

And whether this wave is against the Peacock Federation.

After all, when Peacock Space promoted itself before, it didn't step on the Navigator company.

But just to scare the Peacock Space Agency, is this wave of "self-explosion" a bit too much of a loss?

With a variety of purposes, the world's media gathered in Tianxia Jiangkou City.

At the beginning, some media wanted to conduct a telephone interview first, but the meaning of the Navigator company was very clear: if you want an interview, you can come to the scene and guarantee to give you a big news!

With this, the media is even more hilarious!

"Oh, there's really big news!"

They can write a story on this information, and the name can be called "Big News!" The Navigator company is angry all over the world! 》

When those reporters came to Jiangkou City and gathered around the Navigator Company to prepare for an interview, they found that there were really a lot of peers, and they immediately understood that this was not only a big news, but also a tough battle.

The Navigator Company didn't keep them waiting long and quickly invited them to the company.

Since the completion of the first phase, this is the first time that the Navigator company has been open to the outside world, allowing reporters to come in for interviews.

The reporters sat in battery cars, looking around under the pretext of enjoying the scenery and architectural design, intending to see something.

It's a pity that all the advanced equipment is in the factory, and they can't see anything.

Moreover, the route of the battery car is fixed, and it is not intended to carry them full of turns, and they drive straight towards the destination.

To their surprise, however, the battery car did not take them to the press center, but to the door of a huge factory.

The huge factory block the hot sun in the south, and there are chairs and long tables in the shade, and it is quite cool when the breeze blows.

Merely...... Where is the press conference going to be?

Ahem, yes, that's where the press conference took place, because Navigator hasn't built a press conference center yet.

In their construction plans, it was a secondary building.

Without much nonsense, after all the reporters were seated, Tang Chao and the others also sat behind the table, and two meters behind them was the gate of the factory.

The reporters are talking a lot, not knowing what the Navigator company is going to do, and so far, there is not even a topic.

In the past, when the press conference was held, at least there would be a background of "so-and-so press conference" in the back, but this time there was nothing behind, and it was directly the white gate of the factory.

Tang Chao saw that all the reporters were looking at the door behind him, and naturally knew what they were thinking, because this was his arrangement.

So he smiled and stood up and said, "Okay, the conference will start later, and everyone will have the opportunity to ask questions, but let's decide on the theme of today's conference first......

Speaking of this, Tang Chao paused slightly, and after everyone's attention was on him, he said, "The terminator of the manned rocket!" ”

"Open the door!"

"Kalalala~"

With Tang Chao's order, the factory gate behind him was withdrawn to both sides one by one.

"Wow-"

The audience was in an uproar!

Except for Tang Chao and others sitting behind the table, those reporters suddenly widened their eyes and all stood up!

The photographer in the back moved faster, disgusted by the garbage in front of him, while looking for a new angle, and pointed his camera and video camera at the interior of the factory to take a hard shot.

"Click~"

"Really? Space shuttle? ”

"No, the shape is much sharper than the space shuttle, wait, the abolition of multi-stage manned rockets, multi-stage rockets are dangerous, self-destructing...... Ah, I see, this must be a single-stage orbital vehicle, just like the original adventure star! ”

"No, it won't be the Adventure Star, this aircraft is not that big, at most it is similar to the Adventure Star's technical verification machine 'X-33' aircraft!"

"That's right, no wonder they dared to post that article, it turned out that there was such a flying machine."

"Big news, absolutely big news!"
