Super technology leader

An article by the Star Pilot Company caused an uproar in the world.

Big, big, big wave!

The article was well written. When ordinary people saw it, good guys, it was separated by explosion, it was inseparable, and it collided after separation. Barabara, it was too thrilling.

Relatively speaking, if there are more parts and steps, there will be more problems. This is the same.

For aerospace enthusiasts who know something, they think too much.

"This wave, this wave is the self-destruction of the leader company?"

After all, Navigator’s rockets are also multi-stage rockets, and even the super-heavy rockets under development are multi-stage rockets. At this time, the multi-stage rockets are criticized for nothing and provoke people's fear of multi-stage rockets, which will not do them any good.

This is not blew up, what is this?

The emergence of multi-stage rockets naturally has its significance. It has many advantages, and it is also the guarantee for mankind to land on the moon the farthest.

First, it can throw away unnecessary mass after each stage of work, so as to obtain good acceleration performance during the rocket flight, and gradually reach the predetermined flight speed.

In this regard, the Mark III rocket of the Peacock Federation is just fine. During the flight, two booster shells totaling 50 tons were dragged for 19 seconds, which not only wasted fuel, but also weakened the carrying capacity.

Second, the engines of each stage of the multi-stage rocket work independently, and different engines can be designed according to the flight conditions of each stage to keep the engines in the best working condition, thereby improving the flight performance of the rocket.

After all, at different altitudes and atmospheric pressures, the performance of the same engine is different.

The better combination now is to use liquid oxygen kerosene fuel for the rocket's takeoff stage, which is simple and crude, cheap and easy to use.At high altitude, it is replaced with liquid hydrogen and liquid oxygen fuel. The thin air and extremely small air pressure can give full play to its high specific impulse characteristics.

In this case, there will be a good balance in cost, efficiency, load and other aspects.

Otherwise, all kerosene is simple to make and the price is cheap, but the load is terrible.

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

Although it is said that the aerospace industry "regardless of 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 requirements of the manned spacecraft for flight overload.

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

For example, when the rocket separates and throws away its dead weight, it may not be able to separate, or it may separate earlier or later, or even hit other engines that are just starting to work after separation.

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

It's like a bumper car anyway.

Then the danger arises.

As the number of stages increases, the structure becomes complicated. When the rocket is launched, it will produce huge vibrations, and these vibrations can sometimes be fatal.

There are also many engines, and the number is also mixed, which is also a problem.

In addition, 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 many complex problems, just like rockets are complex aggregates, they are all problems.

Professional aerospace companies and aerospace departments have similar ideas to enthusiasts. After all, they all know how to do it. They don't understand the significance of this article published by Navigator.

If you say self-destruction, you will definitely not. Individuals may not check it for a while and say the best things, but when an article is written, a lot of information needs to be checked. That time is calm enough, and even this article is not necessarily written by one person. .

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

They are not easy to ask, but someone will ask for them.

media!

Interstellar Pilot is not a small company, it is an internationally renowned private aerospace company.

As far as the company's rocket capacity is concerned, it can definitely be ranked in the top three in the ranking of the launch vehicles of private space companies in service.

As for other private aerospace companies that build rockets, either large rockets are about to fly for the first time, or their capacity is only a few tons or even hundreds of kilograms, which is not a threat to Navigator's "Chuohang" rocket.

Even if all the agencies with space rockets are included, it is ranked top.

At least the capacity of the "Chuohang" rocket is stronger than that of the recently popular Peacock Federation "Mark III" rocket.

There is no suspense between ten tons and ten tons.

At this time, when Navigator's own multi-stage super-heavy rocket was being developed, an article like this was suddenly published. The impact can be imagined.

All the media want to know the inside story here.

And whether this wave is aimed at the Peacock Federation.

After all, the Peacock Space Agency used to step on the leader company when it promoted itself.

But just for the sake of the Peacock Space Agency, is this wave of "self-destruction" a bit too bad?

With various purposes, the world media gathered in Tianxia Jiangkou City.

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

With these words, the media is even more cheered!

"Oh Huo, there really is big news!"

They can write a report on this information, which can be named "Big News!"Navigator is angry at the world!

When the reporters came to Jiangkou City and were preparing for interviews around Navigator, they found that there were a lot of colleagues coming, and they all understood that this was both big news and a tough battle.

Navigator did not let them wait for a long time, and soon invited them to the company.

Since the completion of the first phase of the pilot company, this is the first time it has opened to the outside world, allowing reporters to come in for interviews.

The reporters were sitting in battery cars, looking around with the excuse of enjoying the beautiful scenery and architectural design, trying to see something.

Unfortunately, all the advanced equipment is in the factory, and they can't see anything.

Moreover, the route of the battery car is fixed, and there is no plan to take them around the factory, and drive straight toward the destination.

But what surprised them was that the battery car did not carry them to the press release center, but transported them to the door of a huge factory.

The huge factory building blocks the hot sun to the south, and seats and long tables are placed in the shade, and it is cool when the breeze blows.

It's just... the press conference is going to be held here?

Cough, yes, the press conference is held here, because the press release center of Navigator has not been established yet.

In their construction plan, that is a secondary building.

No more nonsense. After all the reporters were seated, Tang Chao and others also sat behind the table, and two meters behind them was the factory gate.

The reporters talked a lot, not knowing what Navigator is going to do, so far, there is not even a topic.

In the usual development conferences, at least there will be a background of "so-and-so conference" at the back, but this time there is nothing behind, it is directly the white door of the factory.

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

So he smiled and stood up and said: "Okay, the press conference will start later. At that time, everyone will have the opportunity to ask questions, but let's first determine the theme of today's press conference..."

Having said this, Tang Chao paused for a while, and after everyone's attention was on him, he said, "The terminator of the manned rocket!"

"Open the door!"

"Ka la la la~"

Following Tang Chao's order, the factory door behind him withdrew one by one to both sides.

"Wow—"

The audience was in an uproar!

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

The photographer in the back moved faster, looking for a new angle while dismissing the junk stuff in front of him, looking for a new angle, and used the camera and video camera to take a sharp shot of the interior of the factory.

"Crack, click, click~"

"What is it? 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 and self-detonate... Ah, I see, this must be a single-stage orbiting 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 aircraft'X-33' aircraft!

"That's right, no wonder they dared to post that article, it turns out that they have this kind of aircraft."

"Big news, absolutely big news!"
