I ask you to build tractors, but you build rockets?

The space agency quickly announced to several affiliated institutes:

Xinyuan Aerospace Power will participate in the overall national aerospace project. Are you studying what tasks can be accomplished with their help?

Of course there is.

First came the Fifth Academy, which threw out a lot of plans and handed them over. The top one was the space station.

According to the original plan, China's space station is divided into three steps. The first step is to verify the on-orbit docking technology of Tiangong-1. The second step is to launch Tiangong-2, which is scheduled to be launched next year. It is the backup of Tiangong-1. The third step is to use the Long March 5 to build a large space station belonging to China in the future.

The classic three-step strategy is also a pragmatic plan based on the space agency’s transportation capacity.

But now that Xinyuan-2 has moved there, the Fifth Academy in charge of the space station can no longer sit still.

This is a heavy-duty rocket that can deliver a payload of 45 tons to low-Earth orbit. The limit of the Chang 5 is only 30 tons, which is not the same level at all.

Tiangong-2 is actually somewhat helpless, limited by the capacity of Long March-2F.

But now if Xinyuan 2 can be used, why not start building a large-scale third-generation space station in one step?

The diameter of Xinyuan-2 is 6 meters, so the diameter of the space station can be 7 to 8 meters, and the length can reach 30 meters. Coupled with the weight of more than 40 tons, the internal space can easily exceed 500 cubic meters. More than ten times that of Tiangong-1!

Even the original third-generation space station plan was limited by the Changwu, and now it seems that it can be larger and heavier.

The Fifth Academy, which does not need to worry about capacity constraints, just let itself go and rolled out several magically modified third-generation space station plans in a few days. As for Tiangong-2, it is just a module in the future plan. If it is not for fear of waste, it can be thrown away. .

In the past, limited by the diameter and weight of the rocket, the docking port of the space station was designed as a space-saving round port with a diameter of 85cm, which was inefficient and small in area. Now it is directly changed to a large square port of 2x2m, which is beautiful and practical.

The tonnage of the core cabin is only 22.5 tons? Directly doubled to 45 tons, two hexahedral node cabins, expanding the capacity to MAX.

The boss even saw the long-term rotating centrifugal module plan to make preliminary demonstrations for the Mars landing spacecraft? ? ?

The boss just skipped it and put it aside, picked up the one below, and the result was even scarier.

"China's Manned Moon Landing Project Plan"

Put it down and pick up another book:

"Moon Resident Scientific Research Station Plan"

Put it down and pick up the next one:

"Research on the concept and demonstration of the spacecraft program for manned landing on Mars"

The boss stopped reading, and felt that the Fifth Courtyard was really floating.

Let’s look at other hospitals.

The first hospital only handed over two symbolic-level cooperation tasks. The main idea is still: Boss, please don’t give up on the Long March 5. Let us struggle a little longer.

Skip it and don’t read it, we’ll discuss this later.

Sixth Academy: Can we jointly develop new engines?

Reply: Get lost, there is no future!

Eighth Hospital: Changliu reusable model is a bit difficult, can we cooperate...

Close and throw aside.

There are no others, because other research institutes mainly send people to the West, and this matter has little to do with them... What is this? A digital code research institute?

The boss opened it curiously and found that this was for research on reusable spacecraft, referred to as unmanned space aircraft, for military purposes.

They found that H1's technology was very important and helpful to the plan, but because the confidentiality level was too high, it was left to the superiors to decide.

The boss couldn't make a decision on his own, so he put it aside and decided to discuss it again when there was a chance.

Just when I felt that there was too much trouble after opening the door, there was a knock on the office door that I pushed open. It was Li Wei.

The boss asked tiredly: "It's Captain Li. What's the matter with coming to my place?"

"It's like this. The team members usually train very hard. Many of them have already reached the standard for astronauts, but they keep putting it off... I heard that H1 can be reused. If we can use it to train astronauts, it will be greatly enriched... …”

Li Wei talked for a long time, from standing to talking to sitting, to standing in front of the big boss's table.

"Li Wei, we have discussed this matter with the comrades of the Manned Spaceflight Office. The superiors have decided to let us adjust the plan. It is possible..."

After a long time, Li Wei was finally sent away. The boss looked at the closed door, picked up the wooden model signed by Chief Engineer Lin Ju that was given to him when Xinyuan 2 was launched, and simulated the re-entry route in the air, slowly Landed on a tabletop imagined as an airport.

…

On June 6, the sixth Falcon 9 of the New Year was erected at the Air Force Base at Cape Caravel.

Lao Ma stood under the scorching sun with a group of specaX R\u0026D personnel.

"Can you promise me that this rocket can be successfully recovered?"

"Of course, Mr. Ma Yilong, this time our improvement has reached 25%. This is the most stable Falcon 9 rocket."

Lao Ma nodded, looking uninterested.

The successful first launch and recovery of Xinyuan-2 left a huge psychological shadow on him. He went to NACA overnight to verify whether Guo Shen had taken away NASA's top-secret technology. If so, he wanted a copy.

NACA: I also want to know where I got these skills.

Originally, he thought that the recovery of Xinyuan 1 would not be too troublesome. After all, Falcon 9 is a medium-sized rocket with a LEO capacity of 20 tons, and Xinyuan 1 was completely incomparable.

As a result, Xinyuan-2, which was 800 tons heavier than Falcon 9, was successfully recovered, which immediately dealt a major blow to him.

How can such a huge rocket and such an outrageous recycling method be achieved?

Ma Yilong, who had not yet successfully recovered the Falcon 9, did not have the confidence he had later. Even when he looked at his own employees, he was a little more suspicious. He fired seven Asan engineers last month.

Caravel has long been used to calling the officers and soldiers at the base. Fortunately, the expensive supplies and aircraft here have been moved, otherwise they would have been blown up by Falcon 9.

The spare parts warehouse that collapsed last time had just been cleared out, and Ma Yilong couldn't wait to shoot rockets again.

specaX engineers expertly entered the launch procedure, and Falcon 9 quickly lifted off and then followed the same trajectory countless times for recovery.

The Merlin 1 engine that has been changed to D type is ignited, the rocket speed slowly decreases, the support legs expand, the altitude continues to decrease, and the engine shuts down.

Falcon 9 stood on the landing site. Although it was off by more than ten meters, it still stood firmly.

Lao Ma, who had his chin propped up, didn't realize what happened for a while. When the recovery was over, he stood up and left with a dull head as usual. After walking more than ten steps, he suddenly turned his head and looked at the Falcon 9 standing in the distance in astonishment. Then he opened his eyes wide and looked at the silent employees, and finally understood.

"W...WOW, wow wow wow! we did it! wei did it!"

"we...did it!"

"ahahahaha!"

Lao Ma was almost in tears at this moment, 8 months, do you know how I got through these 8 months!

In 8 months, there were 7 Falcon 9s. In order to ensure the feat of one rocket per month, the monthly expenses almost doubled, and the employees of Kongcha worked hard overtime to manufacture rockets.

And now, he, Ma Yilong, can finally say that Ami has broken through the technological blockade and mastered independent rocket recovery capabilities!

At this time, netizens who were watching the launch of the Lao Ma rocket were also excited. Lao Ma would live broadcast every launch mission. After performing six consecutive bombings, the Falcon 9 was successfully recovered? !
