This is how black technology should be used

Chapter 162 Starry First Manned Moon Landing Plan

As everyone thought, the unmanned flight of the Freedom Federation around the moon was broadcast live, which also demonstrated their confidence.

Obviously, this early launch did not make them rush, but they were fully prepared.

At least the superficial preparations are adequate.

As for Fanxing, although they said that it doesn't matter on many occasions, in fact, the two sides are now competitors.

This is indisputable and inescapable!

As the second, even if you don't say it, the first will be afraid of you, let alone you are so brave to move forward.

Either rush to the first place, or be beaten to the third place, or even worse.

So this time is not only a major event for the Free Federation, but also a major event for the stars.

When people outside were watching the live broadcast, the Fanxing Space Administration was also watching the live broadcast, and there were various experts present, as well as representatives of various private aerospace companies in Fanxing. Li Weiwei was also present, because he had connections with both parties.

He is not only the chief technology officer of Practical Science and Technology Aerospace Exploration Technology Company, but also one of the technical consultants for the manned moon landing project of Star Space.

Ordinary people think that Long March [-] has not been found. In fact, with Li Future joining, Long March [-] is also accelerating its development, and does not want to do any post-production and improvement upgrades. Many technical projects have also been deleted. In this analogy, the progress is actually faster. up.

Previously, because the Long March [-] did not have an overall project approval, the specific configuration of the Long March [-] has been controversial.

The old version is similar to the enlarged version of the bundled Long March [-], that is, the main rocket has four boosters.

The new version is a bare rod type without boosters, similar to the Saturn V rocket of the Freedom Federation, but the number and arrangement of the nozzles are more like the old Maozi's N1 rocket.

But since Li Weiwei joined the Long March [-] project, there has been no controversy within the project team, because the Long March [-] does not consider the later stage, and its historical mission is only Fanxing's first manned moon landing, so it uses a more mature one. Old version.

After all, the design of each subsystem is related to it, or its configuration is designed based on the data of each subsystem.

It is equivalent to building as many cars as there are functional machines.

So while watching the live broadcast of the Free Federation's SLS rocket preparing for its first flight, Fanxing Space Agency was also discussing it internally.

"We have received some news from Europa Space Agency, Izumo Aerospace Agency, Kangaroo Space Agency and other places. According to the original plan, some of their experimental facilities are going to take the first SLS rocket to the moon, but now their test equipment is not available. Without a rocket, it is obvious that the Freedom Federation has destroyed the overall plan."

"You mean, there is a lack of communication between the two sides, one side is speeding up, but the other side is following the steps, that's why this happened?"

"Well, and we feel that their lack of communication is passive. The Freedom Federation probably didn't want to launch so quickly, but encountered force majeure, so they had to launch so quickly."

"Whatever, anyway, judging from the various steps, their launch should be successful this time, unless there is some accident, so let's think about our own affairs."

"So, when will our moon landing rocket be launched?"

This is a good question. The Freedom Federation has accelerated, so should I also speed up on my own side?

In fact, the progress of the Long March [-] has been accelerated. Not only has the secret overall project been approved, but also the new technology adopted in the old configuration not only uses a common bottom storage tank to reduce the structural weight, but also shortens the rocket body.

At the same time, the wireless transmission technology of practical science and technology is adopted, which not only cancels the complicated lines, but also reduces the interfaces that need to be checked, reduces the design and inspection work, and further reduces the structural weight.

If the rocket's self-weight is reduced, its carrying capacity will increase a little.

The newly finalized Long March 93 super-heavy carrier rocket has a height of 28 meters. Intuitively, the height is almost equal to the height of a [-]-story building.

Its core stage has a diameter of 10 meters, and its launch weight has reached 4140 tons, which is close to the displacement of more than 054 tons of the 4000A frigate, while the maximum take-off thrust has reached an astonishing 5873 tons.

At the very beginning, because of Fanxing's conservative character, the maximum carrying capacity was 140 tons. Now that the whole sequence of improvements has been made, relevant staff dare to say that its maximum carrying capacity can reach 180 tons!
Some people even secretly calculated that it would be enough to transport 200 tons of things to low-Earth orbit.

However, the data belongs to the data. In reality, there is no 200-ton load that requires it to be transported to low-Earth orbit.

After all, the second complete body of the Tiangong Space Station does not have 200 tons, and the second complete body of the Tiangong Space Station cannot be stuffed into the fairing of the Long March [-].

The earth is not a magical Kerbal, and any weird fairing can enter space.

So if the Long March 200 really wants to carry a load of 180 tons, or even the [-] tons in the label, unless it is carrying a large concrete pier.

There are so many markings, but its designers know that it was only made for Fanxing's first manned moon landing. After completing this mission, it was retired.

If we follow the three-step approach, the first one will be unmanned around the moon, the second one will be manned around the moon, and the third one will be manned to the moon, a total of three will be built, so simply give it a very high index and make it a certain kind of The degree of the world's first.

It is not in vain for its contribution to the stars.

In fact, at the beginning, there was not only the Long March [-] manned moon landing plan, but also a plan provided by netizens.

Yes, as far as netizens are concerned, after all, Fanxing’s project related to manned moon landing has not been approved, so many things are based on the imagination of netizens.

For example, using a new generation of manned rockets to achieve manned landing on the moon.

Fanxing's original manned rocket is the Long March 8F rocket, which can carry the [-]-ton Shenzhou manned spacecraft into orbit.

The diameter of the Shenzhou manned spacecraft is only more than two meters, which is just enough to carry three astronauts into space.

But with the diversification of missions, and even the manned moon landing technology will be implemented in the future, the 8-ton Shenzhou manned spacecraft will not be enough.

So there is a new generation of manned spacecraft.

The new generation of manned spacecraft is much more powerful, with a diameter soaring to more than four meters and a weight of more than 20 tons.

With such a large spacecraft, it can easily carry 7 astronauts into the sky, and it can also carry some cargo by the way. If the number of astronauts is reduced, it can carry more cargo.

And it also has its own toilet, and astronauts can go to the toilet inside.

This is for manned landing on the moon.

The large cabin not only has a large space, but also uses good protective materials. Not only can it resist the cosmic radiation far away from the earth, but it will not be burned when returning to the earth at a super high speed from the moon.

And it can be reused.

But such a new generation of manned spaceships, such as the Long March [-]F, can no longer fit in a small old rocket. Not only can it not fit in the fairing, but even if it is installed, it can't fly.

It can only transport the 8-ton Shenzhou spacecraft, and it can't do anything for the new manned capacity of more than 20 tons.

Therefore, a new generation of manned rockets is needed to carry this new generation of manned spacecraft.

The data of the new generation of manned spacecraft is good, and the rocket body is also as high as 90 meters, almost as high as the Long March 30, and more than [-] meters higher than the Long March [-].

Its take-off mass is about 2211 tons, and its carrying capacity is about three times that of the basic version of the Long March 70. The maximum carrying capacity of the low-earth orbit is 32 tons, the maximum carrying capacity of the geosynchronous orbit is 25 tons, and the carrying capacity of the lunar orbit is about [-] tons. .

The low-earth orbit carrying capacity is 70 tons, and a new generation of manned spacecraft that can transport more than 20 tons is of course trivial, but what netizens value most is its 25-ton lunar orbit carrying capacity.

The reason why they value this is because the original moon landing plan of the Freedom Federation did not have the Saturn V fly directly to the moon and then perform acrobatics in lunar orbit, but chose the Saturn V plan out of four.

The first plan was to take off directly.

This plan proposes that a huge new rocket carry a spacecraft directly to the moon, then the rocket lands on the moon, takes off again after the mission is completed, and flies back to Earth.

It can be said to be quite awesome and sci-fi, but the difficulty of implementation is also at the sci-fi level.

The second option is the Earth-orbit rendezvous.

The plan would simply require two "small" rockets half the size of the Saturn V to launch the different parts of the lunar spacecraft into Earth orbit, then rendezvous and dock.

After that, the entire spacecraft flew to the moon and landed on the lunar surface.

It's just that there was little experience in assembling multiple spacecraft in orbit at that time, and it was unknown whether the assembly of spacecraft in Earth orbit was feasible, so this plan was not adopted.

The third option is to rendezvous on the lunar surface.

The plan calls for two spacecraft to be launched, an autonomous spacecraft carrying a propulsion system, to land on the moon first, followed by a manned spacecraft later.

After completing the mission, make a small "modification" on the surface of the moon, and then return to Earth in the modified spacecraft.

The fourth plan is the final lunar orbit rendezvous plan.

This solution requires a new type of manned spacecraft, and then carries a lunar landing module loaded with astronauts. The new type of manned spacecraft carries fuel and daily necessities from the earth to the moon and back, and can isolate the universe as much as possible. radiation.

After entering lunar orbit, the lunar module is separated from the manned spacecraft, and then the interface is docked with the interface, allowing two astronauts to enter the lunar module and land on the surface of the moon, while one astronaut and the manned spacecraft remain in lunar orbit.

After the moon landing was completed, the lunar module took off again, and the manned spacecraft assembled in lunar orbit and returned to Earth.

Different from several other programs, this program only requires a very small spacecraft to land on the surface of the moon, so that the mass of the spacecraft that takes off on the moon when returning is greatly reduced.

By leaving part of the lunar module on the moon, the lunar module takeoff mass was reduced again.

The lunar module itself is divided into two parts, including the landing part and the take-off part. The former is used to land on the moon, and the latter takes off to rendezvous with the manned spacecraft and return to Earth after the mission is completed.

Due to the reduced mass of the spacecraft, only a single Saturn V rocket launch is required for a mission.

The Saturn V can transport 45 tons of load to the lunar orbit at one time, and the new generation of starry manned rockets can transport 50 tons twice, which is enough to land on the moon and return.

Because of its relatively small single load, the first and fourth schemes are not considered, but the second and third schemes can be considered.

No, the second half of the fourth plan can also be considered.

Times are different now. With the development of technology, docking in orbit is no longer a difficult task. Whether docking in Earth orbit or docking with stars in lunar orbit has been done, and it is very successful.

Even the previous Chang'e-[-] lunar sampling process can be regarded as an unmanned mini version of the manned lunar landing and return drill.

So some talented netizens combined the historical experience of the Freedom Federation, combined with the current technological development and related technologies owned by Fanxing, and came up with a plan to use "small rockets" to carry out manned moon landings.

That is to use two new-generation manned rockets to launch a new-generation manned spacecraft and lunar module, and then it doesn’t matter whether they are combined in Earth orbit or in lunar orbit.

Anyway, the stars can be combined on both orbits. As long as some corresponding trade-offs are made, the chances of realizing the manned landing on the moon with the stars are very high.

Moreover, the time for using a new generation of manned rockets to carry out the first manned mission to the moon is very fast. Assuming that the Long March [-] will take ten years to prepare, then the new generation of manned rockets may only take about five years, which is almost the same as the return to the moon of the Freedom Federation. The time has overlapped.

Because the new generation of manned rockets is composed of a large number of mature technologies, theoretically the development time will be very fast.

Its arrow body diameter is 5 meters in diameter of the Long March 5, and the engine is the same as the Long March [-]. A lot of technology is related to the Long March [-], so it is also an alias given by netizens, which is "CZ-[-]DY", which means "Long March [-] moon landing type" rocket.

However, the SLS rocket of the Freedom Federation also uses a lot of space shuttle technology, and it should be fast in theory, but it took ten years to complete.

It still counts its current launch time ahead of schedule, or it will take longer if the first flight is counted next year.

Originally, many people were looking forward to the two "small rockets" manned to the moon, not only those anxious netizens, but even many professionals were looking forward to it, because after completing the feat of landing on the moon, Fanxing China will definitely If the aerospace craze kicks off, the salary and status of professionals like them will definitely increase dramatically.

It's just that with the addition of Li Future, their wishes are completely gone, because compared with Li Future's follow-up space program, the new generation of manned spacecraft, the new generation of manned rockets, the Long March [-] super-heavy rocket, etc. outdated.

Their brilliance and mission are only Fanxing's first manned landing on the moon, and even the new generation of manned rockets that had high hopes are gone.

Because only the new-generation manned spacecraft and the Long March [-] can be used for the first manned landing on the moon, three of them were built on the Long March [-], and the new-generation manned spacecraft can be reused ten times, so it is enough to build one.

Save a batch!
and so……

"The first flight of the Long March [-] will definitely not catch up with the SLS rocket that is about to fly now, but it should be able to make its first flight early next year, or even at the end of this year."

"However, I am confident that the first flight may not be able to catch up, but the time for manned landing on the moon should be faster than that side."

Li Future said while crossing his arms.

"Really?"

Some people don't believe it, "The opposite is the first flight this year, the moon next year, and the moon landing the year after."

"Of course," Li Future is still confident: "Our process of building Long March [-] is no longer very traditional. Not to mention other things, let's just say that there is not a single cable in it, which saves us a lot of design, inspection and manufacturing. time?"

"There is also a real intelligent self-inspection and intelligent simulation system. You have all seen it. What do you think?"

"So, let's broaden our horizons and be bolder!"
