Fortunately, the B+-level foundation is not covered, and Guo Shen quickly thought of a fast and stable plan:

"The four H240s are slightly separated, and an H80 engine is stuffed in the middle, which is normally blocked by four large nozzles and cannot be started, and the four H240s are opened outwards to the maximum during recovery, and then the 80-ton hydrogen-oxygen engine H80 in the middle is started for the recovery process."

After drawing a few times on the tablet with X32035 installed, a feasible plan was displayed in front of Lin Ju, who nodded with satisfaction:

"How long will it take for this secondary modification to be completed?"

"It will be able to be used next month, not much has changed, now we have made six second stages, and it is too late to modify two axial modules for the launch of two advance numbers, and the rest can be done."

"What is this?"

A voice came from next to the two, and then poked through the big guy's gray hair.

The big guy was staring nervously at the recovery process of the first level of Xinyuan 3 next to him, full of expectations for this unprecedented heavy rocket recovery.

Unlike the previous recoveries, the engines of Xinyuan-3 are constantly igniting intermittently for three circles, which looks irregular, but the attitude of the rocket is extremely stable.

Much of the credit for this goes to its own weight, with the 19 engines at the bottom making the center of gravity of the rocket too downward for the average wind to blow at all.

It looks like a Xinyuan-2 first-stage PLUS The recovery process of the Xinyuan-3 first-stage rocket is also silky, and it is also gently hung on the recovery tower.

There was no accident at all when the 77-meter-high rocket hung on a recovery tower more than 100 meters high, and it was more stable than hanging a spoon on a wall nail.

Such technical power is both reasonable and unexpected.

The general public only felt very shocked, and the aerospace practitioners could not believe that this was something that human beings could do.

How can such a complex rocket, such a complex recovery procedure, be successful at one time!

This is fucking unscientific!

The big guy was already numb and accustomed to it, he was just surprised by Lin Ju and Guo Shen's flat expressions, and wanted to see what they were discussing, and he was so indifferent to the world's No. 1.

"Recycling Level 2? So you can recover at least 80% of the cost, right? ”

Lin Ju shook his head: "Not so much, 75%, liquid hydrogen is too expensive, storage and transportation are troublesome, the performance of the second level is good, but the fuel cost is not low." ”

In fact, the cost of rearmament and launch of Xinyuan-3 without recovering the second stage is about 500 million yuan, which is nearly four times that of Xinyuan-2.

Recycling the second level can save at least 110 million and reduce the cost by more than 20%, which is indeed not low, and it is already at the same level as Xinyuan No. 2A, which is obviously more cost-effective, and can also use one less recycling station.

As for the three-stage rocket, it really can't be recovered, the three-stage is headed for the moon, and it is obviously unlikely to fly back.

Big guy: "How long will it take for the No. 3 rocket to be reconditioned and launched again?" ”

"For more than half a month, this rocket is too big, and the number of personnel occupied is not small."

Half a month, half a month.

The Long March 10 rocket and space agency can build one launch in eight months, and if it does not cost anything, it may be able to build one launch in six months; In the last century, Aramco built the Saturn V, which can be launched almost twice a year.

Now, the giant rocket Xinyuan-3, which has a capacity of 100 tons more than these two rockets, can be launched once every half a month.

That is, one rocket can be launched 24 times in a year, projecting more than five thousand tons of mass into space!

This gap is simply unattainable.

It is no exaggeration to say that once Xinyuan-3 is launched, the mass of its orbit will exceed that of the world last year combined.

The expectations of the big guys for the Long March 9, the new Long March 5 and the Long March 15 are becoming more and more urgent.

……

After the successful launch of Xinyuan-3, it immediately aroused strong repercussions in the world.

"The world's largest rocket with the largest diameter and the strongest carrying capacity successfully made its first flight at the Qiongzhou Cosmodrome"

"Multiple parallel units are the future! The N1 spell will be broken. ”

"Why was Xinyuan No. 3 born?"

"Ma Yilong: Starship will complete the iteration from SSN-2 to SSN-9 within 5 months, and the combination will achieve its first flight next year."

"Yuri, director of the Lucia Space Agency, declared: Huaguo Aerospace is already the first in the world."

"NACA congratulated the successful launch of Xinyuan-3 and said that the SLS rocket is about to make its first flight, and the human space industry is entering a new era."

"The scores of these majors of Southern University of Aeronautics and Astronautics exceed those of Peking University and Tsinghua University!"

Seems to have mixed in with something strange, especially the last one.

Theoretically speaking, it is normal for universities to have different application scores for various majors, and some universities have special advantages in a certain major, and there are many more than Peking University and Tsinghua University.

But Southern University of Aeronautics and Astronautics is different, his entire college, that is, the School of Aeronautics and Astronautics, the scores of various majors under its jurisdiction have reached a very exaggerated level, far exceeding the school level.

In fact, not only here, but also several other colleges and universities have a few majors with particularly high application scores.

The reason is naturally very simple, these are all majors that are highly cooperative with Xinyuan Aerospace Power.

Since Lin Ju announced the free "take-off" last fall, these related majors have become popular on this basis alone.

It's another year of college entrance examination and it's time to fill in the volunteer season.,Prospective college students who have long been stimulated by the countless flight VLOGs of their seniors are very happy to apply for the exam.,And it's local.,How good.。

The Xinyuan-3 rocket made its maiden flight again, and the Southern University of Aeronautics and Astronautics and several other colleges and universities posted their own personnel involved in it, and even more gilded these majors.

In the past year, Xinyuan has cooperated very closely with these institutions, and many of the teaching materials taught by students are written by engineers in the base, and the technical specifications and design points are all for Xinyuan Aerospace.

At every turn, students are brought to visit the B-level base or C-level base, and from time to time the An-1250 and Il-76 fly overhead, and sometimes they can even be led by instructors under the concession to fly over the huge base of Xinyuan Company.

In the future that Lin Ju described to them, they will learn the aerospace technology of Xinyuan Company in their entirety in college, and they can fly for free in their spare time, and they will directly prepare astronauts.

One day, maybe you will be riding in your own spaceship and going to space to work!

This treatment, not to mention the general 985 and 211, can even Peking University and Tsinghua University give it?

So even if Lin Ju didn't ask for a mandatory employment agreement, these college students couldn't get out of the way and were willing to sign a deed of sale.

Naturally, these majors are rising, the quality of teaching is high, and almost all of them are allocated, and they have entered the world's top manufacturing enterprises, which cannot be found in the whole country, right?

The school leaders boldly raised the score line, which made a group of students complain, and the old seniors rejoiced.

However, the number of applicants is still large, and the requirements are still met, which makes the leaders sigh that they have finally got a good source of students.
