This star is going to the moon

Chapter 112 The culmination of the 'Technology Integration Theory' rocket!
"I?"

Lu Yun pointed at himself.

"Yes, Comrade Lu Yun."

A middle-aged man leaned over and said, "Your 'starship' is indeed impressive, but it requires too many new technologies. It doesn't quite match your 'technical integration theory'. I'm not sure it will produce any results in the short term."

"Why don't you come to our First Academy and take a look at our super rocket, the Long March 5? Its design incorporates a lot of existing technologies. For example, the four boosters use the -meter diameter body design of the Long March ."

"Also, the Long March 9.5 rocket still has a 10.6-meter diameter core stage to research, which is similar to the -meter diameter of your Starship rocket."

"Look, participating in the Long March 9 rocket development mission not only allows you to continue training and enrich your own 'technical integration theory', but also helps your 'starship' development. How great is that..."

"Hey, Comrade Lu Yun, don't listen to Old Zhao's nonsense!"

A middle-aged man in front of Lu Yun turned around and said, "They've been talking about the Long March 9 for years, and yet none of its subsystems are ready. It's a huge waste of time and money."

"Why don't you come to our Eighth Academy? We're planning to directly modify the Long March 5. Almost everything is already available, perfect for you to apply your 'Technology Integration Theory'. Not only can it be done quickly, but it's also cheap."

"You and I are a powerful alliance. As long as we can prove that the modified Chang Wu can work, the higher-ups will definitely approve the project immediately."

"Not only will your Starship research not be delayed by then, but with its status as a manned lunar landing platform, your Starship will have no shortage of future orders. The construction of a lunar base will require a super rocket with enormous carrying capacity like the Starship..."

"It's better for me to come to our academy, so I can improve my technical level!"

"Come to our Eighth Institute, where the technology is mature and the R&D speed is fast!"

"First Courtyard..."

"Eighth Hospital..."

More and more bigwigs from the two houses came to try to win over Lu Yun to participate in their projects. No one looked down on him just because he was a young man who had just turned 25.

You even have to watch it again and look at it with a higher regard!
Because Lu Yun is no longer the "unknown" person he used to be, but a space boss who has led his team to develop the country's first reusable rocket.

What's more, they have their own aerospace company, so they can basically develop whatever rockets they want, unlike them who have to follow national missions.

Now that we finally have the opportunity to actually land humans on the moon, we naturally have to use our own new rocket to carry them aboard. Having another talent like Lu Yun will greatly increase the chances!
Fortunately, Director Zhang was still maintaining order at the scene and quickly called them back.

"They're all elderly aerospace engineers, and they're making this place look like a market. How can that be?"

Director Zhang scanned the scene and continued, "You have your own new rockets, but Lu Yun doesn't have his own new rockets? Are you so sure that Starship can't be built in a short time?"

"Alright, everyone, sit down. Since the comrades from the First and Eighth Institutes have both mentioned their rockets, Lu Yun, can you also tell us if your 'Starship' is confident enough to get approval from higher-ups for a manned lunar landing program in the near future?"

Lu Yun already had a plan in mind, so he was a little confused when he heard them talking about "starship" in long and short terms. Now that he was asked to speak, he decided to speak.

"In fact, the Starship cannot be built in a short period of time. It is impossible to have it participate in the initial manned lunar landing plan."

As soon as Lu Yun said this, the expressions of those who had just mentioned the "starship" issue were quite interesting.

The younger ones gathered together to play with crickets, while the older ones immediately raised their chins to Director Zhang.

Director Zhang: “…”

In fact, Lu Yun’s “in a short time” is different from what they understand as “in a short time”.

However, he didn't intend to say "Starship," so he didn't explain. Instead, he continued, "I also envision a new type of rocket based on the Long March 5 rocket technology. It is the culmination of the 'technology integration theory.'"

"This rocket has removed the 3.35-meter booster of the Long March 5 and uses only a 100-meter diameter core stage rocket. However, the fuel is liquid oxygen and kerosene. The first stage rocket engine is an upgraded version of the YF- used in the seven boosters, and the second stage has two engines. The rocket is reusable and reusable."

"It will adopt a model similar to the Falcon 25 and Falcon Heavy, with a bare-rod, two-stage configuration with a takeoff mass of to tons. In recovery mode, it will also have the same -ton low-Earth orbit capacity as the Long March ."

(Internet photo, modified by Photoshop) "And its lunar landing version uses a CBC configuration similar to the 'Heavy Hunter', that is, three 5-meter diameter core stages tied together for takeoff."

"The intermediate rocket will add a liquid hydrogen and liquid oxygen third-stage rocket to the second stage to increase its high-orbit transport capacity. The engines used will be three YF-75Ds, which are the second-stage engines of the Long March ."

"The takeoff mass of the lunar landing version is more than 2000 tons, and its lunar orbit carrying capacity in recovery mode can reach 25 tons."

Lu Yun said this and looked at the people from the First and Eighth Hospitals, then... opened the gun.

"In my opinion, adopting the American Apollo lunar landing program, that is, directly launching a super rocket to achieve a manned lunar landing, would require a rocket with a capacity of more than 120 tons for low-Earth orbit and more than 40 tons for Earth-Moon transfer orbit. It is difficult to develop and too radical."

"The three-launch plan to complete docking in low-Earth orbit and then head to the moon requires the least rocket capacity, but the entire process is too cumbersome."

"The main thing is that disposable rockets are too outdated!"

"Only by using reusable rockets can we reduce costs as much as possible. My proposal is to complete the lunar landing in two launches. It is a compromise and can also reduce the cost of the entire manned lunar landing project to about ten times that of the Chang'e 5 project."

"That is the 300 billion RMB that we initially imagined to be the most 'dreamy'!"

quiet!
silence!

After Lu Yun finished saying this, the whole scene became very quiet and everyone was stunned.

"Danglang~"

Someone's signature pen fell, startling everyone and causing the scene to immediately turn from quiet to noisy.

"Is this possible?"

"The rocket body is the mature 5-meter diameter Long March 100 rocket body. The first and second stage engines are modified versions of the Long March 75 booster, the third stage uses the Long March second stage's YF-D, and the recovery technology uses an improved version of the Wanhu rocket recovery technology..."

"hiss--"

"Although many technologies need to be improved and upgraded, they do have prototype references. This new rocket is truly the epitome of the 'Technology Integration Theory'!"

"Most importantly, it can be used to enable our country to realize its dream of landing a man on the moon!"

Director Zhang, who was presiding over the meeting, was also stunned.

It seems that this seminar is just discussing the feasibility of sending humans to the moon?

Then at the beginning...

feasibility?
Let’s start discussing what rocket to use to carry out manned lunar landing!
This is...ok, it doesn't go beyond the scope of feasibility discussion, at most it's a step further.

As a result, the two domestic units responsible for rocket development were directly rejected by Lu Yun, and then he came up with an even more outrageous rocket!

The most important thing is that the feasibility of this rocket is higher than that of the rockets of those two units!

It's even a reusable version, and can be recovered for manned lunar missions. At most, the second and third stage rockets will be discarded, but the largest first stage rocket can be recovered and reused.

This is simply awesome!

According to the country's "frugal" character, there is no need to look at the rockets of the other two companies, just take this one!

When Director Zhang looked at Lu Yun again, his eyes were filled with emotion.

"He's only 25."

"It is a blessing for the country and the nation!"
