"In order to make this mission as simple as possible, I also took great pains."

"The rocket body selected a 2.5-meter-diameter extreme rocket Jumbo-64 fuel tank, the core stage and booster are all this, and it is easier to manufacture after the diameter is unified."

"The types of engines have also been reduced, and the engines of the booster, first and second stages are all RE-M3 'mainsail' engines, which are very reliable."

"There are also spherical fuel tanks of the same model, lines of the same model, and ...... of the same model"

Tang Chao pointed to the big screen and told them about the characteristics of this rocket one by one.

This rocket is really minimalist to the end, all kinds of equipment and parts are unified, and it is extremely manufacturer-friendly.

The smaller the diameter of the rocket body, the less difficult it is to manufacture, and as far as his observation is concerned, the diameter of two meters and five is not difficult for domestic private space companies, and they now have no problem manufacturing more than three meters in diameter.

To "save effort" for the manufacturer is to "add strength" to his plan, which is why he did not want to use the Long March 9 to compete.

Let's not say that the Long March 9 is a representative work of the country, and it is used by the country to scare the moon.

If you don't have some money, you may not care too much, but sometimes you lose face, and you will be really anxious.

So he definitely wouldn't do this kind of thing.

Moreover, the Long March 9 is too big, with a height of 100 meters and a diameter of 10 meters, as well as an ultra-large thrust engine, an arrow body of extreme materials, etc., which are too restrictive.

Before buying his skills, it was difficult for the national team to make this kind of thing, let alone the private companies below.

Effort wastes time and wastes money.

He Tang Chao has always been diligent and thrifty, and he will definitely not spend this kind of unjust money.

And one of the most important ones.

Even if he really uses the Long March 9 as a competition rocket, there must be a launch pad in China that can reflect such a large rocket.

Not at all.

Such a launch pad has just begun to be built.

The rocket was built first, but the launch pad has not been built yet, so you can only wait, so who can stand it.

Therefore, the diameter of the arrow body is still two meters and five, and the technical content is relatively low, even if the technology provided by him is not used, a private company can build it, at most, it can be made a little bigger.

After listening to Tang Chao say this, the technicians who just went to work today agreed very much that this rocket is really suitable for this competition.

The technology is mature, and the manufacturing difficulty is low, so it should be able to be made in a short time.

Time is of the essence when it comes to the game.

And after making it, it can be used not only for competitions, but also for everyday life.

Don't look at the take-off weight of this rocket is only 400 tons, but the load ratio is very good, it can reach 4.5%, and theoretically can carry the weight of 18 tons to low earth orbit.

But theory is theory, their rockets are too thin and not strong enough.

If it really carries a load of 18 tons, it will definitely bring abnormal pressure to the rocket body, and the rocket will bear a lot of G-force and jitter during flight, so the probability of rocket failure will be greatly increased.

To put it simply, it can be lucky, but the success rate is not guaranteed.

It doesn't matter, the theoretical load can't be transported, and 13 tons of things can still be transported to low earth orbit with a guaranteed safety.

This comprehensive strength is more powerful than Tianxia's "model worker" Long March-3 series rockets.

Coupled with the minimalist structure of this rocket, the diameter of the rocket body is unified, and the main thruster model is unified, which is very conducive to the development of modular manufacturing mode, which can further save costs while improving the success rate.

And the main engine is there, and other rockets can be developed.

Good guys, the liquid rocket engine with a thrust of 140 tons is definitely the largest thrust in the domestic private aerospace field, and other private companies have a thrust of more than 70 tons at sea level at most, and a single thrust of less than 80 tons.

Compared with the national team, before the relevant technology of the Long March 9 was unveiled, the thrust of 140 tons was not worth it.

On the basis of such an engine, the development of a large-diameter rocket body, with several engines connected in parallel, it is definitely possible to develop a large launch vehicle.

The thrust of eight engines can be stacked to the level of the Long March 5, and the number of engines is two less than that of the Long March 5.

That's the benefit of a high-thrust engine.

If you are a little more daring, pile up a dozen or twenty engines, learn from the heavy Falcon, and it will be enough to build a rocket for landing on the moon.

An engine has such capabilities, and the future of the company is absolutely bright.

It's a pity that the company's official factory building has not yet been seen, these are just the assumptions of the future, and the most important thing now is the moon landing Grand Prix.

"Boss, the two-meter-five-diameter rocket body can be made in my previous company, and their current main rocket is the two-meter-five-diameter rocket body, find them to build the fastest, as long as the requirements are sent, they can be produced immediately."

"Okay, make a note first."

"About engine manufacturing, boss, I feel that the blue sword and Kyushu can be built, and they have the strongest liquid rocket engine technology in the domestic private aerospace field, and they have mastered the manufacturing technology of 80 tons of thrust, and are making a breakthrough to more than 100 tons."

"Okay, make a note of that too."

"Boss, I know a company that does a very good job in flight control technology......"

"Boss, my previous company did a good job of making separating rings......"

"Boss, our teacher has a small company, and they do radar communication ......"

"Boss, my classmate's company does a good job of making solar panels......

Everyone, you and I said a word, and soon found the manufacturers of parts for rockets and probes, and this is the power of circles.

Even if you don't know it, there are people in your circle who know it.

Obviously, Tianxia's aerospace industry has a certain scale, but it has not been effectively utilized.

The above must also know, so the formal aerospace law has been promulgated, intending to integrate domestic aerospace resources, formulate a new aerospace strategy, and ensure the win-win development of private aerospace companies and the national team.

And his account has begun to have "loose money" remitted in.

"Loose money" is not only the fixed billions of remittances at the beginning of the month, but also hundreds or tens of millions of dollars in the first few days.

Obviously, the top has begun to use his technology to make a big strategic layout, accelerated the escape and sinking speed of high-precision technology, and began to upgrade the domestic civil field technology.

So he got the commission mentioned in the previous contract.

He did it above, and he Tang Chao also did it.

This time, he didn't plan to pay a penny for processing parts from a private aerospace company, and he planned to let those companies give him money.

He's going to trade technology for parts.

Hearing him say this, everyone present was stunned.

Generally, companies keep their own technology very tightly, and they must not let their peers learn it.

As the saying goes, "peers are enemies".

Just like those mobile phone manufacturers, every day "friends and friends", as a result, when the new product launch conference is to use the "friends" of the mobile phone to highlight their new mobile phones more criticized, how can there be a little "friend" meaning.

Why did his own boss really want to be a friend businessman, and he actually spread the company's new technology outward.

Facing everyone's puzzled faces, Tang Chao smiled slightly: "I have always thought that the sentence 'a single flower blooming is not spring, a hundred flowers blooming in spring' is very right." ”

It's good to be alone all the time, but it doesn't just mean beauty, it also represents loneliness and the cold winter that hasn't passed.

The flowers bloom early.

The dawn before dawn is the darkest, and before the real spring arrives, any warmth represents an even more bitter cold.

It was a very warm day, the flowers bloomed, but the next day there was a cold spell and he died immediately.
