This star is going to the moon

Chapter 27 The world line ends

Lu Yun is well aware of the domestic aerospace agencies’ pursuit of “stability”.

Take the Long March 5 rocket for example. Although its design incorporates many new technologies, it is generally conservative and seeks stability.

The Falcon 549 has a takeoff mass of 22.8 tons, and its theoretical one-time carrying capacity without recovery is 4.15 tons to low-Earth orbit, so its load factor is %.

The Long March 869's takeoff mass is 25 tons, and its theoretical low-Earth orbit carrying capacity is said to be 2.87 tons, with a carrying factor of %.

Another saying is 32 tons, so the load factor is 3.68%.

However, the reason why these are all "theoretical" low-Earth orbit carrying capacities is that they are basically not used, but no matter what, 2% and 3% are not as good as 4%.

In addition to the technological gap, another reason for this situation is that the Long March 5 was developed by a conservative official aerospace agency, while the Falcon 9 came from a more radical private enterprise.

The Falcon 9 pursues maximum profit and extreme lightness, so the rocket's ability to cope with environmental changes is slightly worse, and it cannot be launched if there is even a slight disturbance.

In the following years, the Long March 5 was called a "thermos cup" by space enthusiasts, meaning that its cabin walls were very thick and its structure was very bulky.

It was not until later that the Long March 5 carrying the Chang'e 6 probe took off violently in heavy rain and an eight-force gale!
At that time, almost everyone thought the launch would be canceled, but the Long March 5 was launched smoothly.

Lu Yun knew that such a thing would happen, so he predicted that the Long March 5 team would definitely switch back to a conservative plan after discovering the problem to ensure the smooth launch of subsequent Long March 5 rockets.

The Long March 5 R&D team is full of experts, and the plan is ready. They should not need to ask him, a newbie, for help, but he still answered the call.

It was typed by Academician Ye Jianfei himself.

And it's not that they want him to assist in research and development, but that everyone wants to meet this young talent, chat with him, and stroll around.

In later generations, many official organizations’ new media accounts like to interact with internet celebrities. For example, some official accounts that have settled in Bilibili like to interact with UP hosts and shoot videos to show themselves.

Some people from the aerospace agency went in and took pictures of the diversion trough directly, calling it the "diversion trough" private room.

There were also people who were invited by the nuclear power plant, and when they entered, they started with some ridiculous topics like "I want to do the butterfly stroke in a boric acid pool".

Anyway, some are quite serious, and some are quite funny.

Then Lu Yun will go. Although it is close to the New Year, it won’t affect the New Year celebrations.

Moreover, he had never been to the Sixth Hospital in his previous life, so this was a good opportunity to take a look.

So when the Falcon 9 rocket on the other side of the ocean finally resumed launching after being grounded for several months, Lu Yun came to the Sixth Academy.

He came here by himself and brought a sports camera with him. He took pictures as he walked, which gave the impression of a vlogger shooting on a small website.

"Can I open another 'big account' and guest-post a knowledge section UP master on this small broken station?"

The person who received Lu Yun was a doctor in his twenties named Wu Di. He also graduated from the School of Astronautics of Jinling University of Aeronautics and Astronautics and was Lu Yun's senior.

It was also he who proposed to invite Lu Yun.

"I saw your performance in 'Longing'. Writing a space essay on a variety show is a famous scene for us aerospace professionals. It's been circulating in several of my school groups. At first, we were still analyzing what you were writing about, but we didn't expect to see it in Academician Ye's hands the next day."

Wu Di gave a thumbs up and said, "Brother, you are really awesome!"

Everyone was carrying the sedan chair, and Lu Yun also said, "Senior Wu is really amazing. Our teacher told us about you in class. You joined the core research group of the Long March 5 team at such a young age."

"Oh, what's so great about that," Wu Di waved his hands: "Fortunately, you got your paper in time, otherwise, given the status before the Long March 5, the launch of Yao 2 would most likely have to use 'turtle jelly'. Now, while there is no major problem with the rocket, we can..." The "turtle jelly" Wu Di mentioned is "return to zero", which means that once a spacecraft has a major fault or a major problem that leads to mission failure, it needs to be checked from the first step to the last step from zero until the problem is completely solved.

For example, if there are 10000 steps in the process of launching a rocket, and it is found that a fault occurs in the 5301st part, causing the mission to fail, then it is definitely not enough to just correct the 5301st part, but all 10000 steps must be started over again.

Therefore, once a space mission fails, the recovery time is much longer than in other industries.

At least that's what the official conservative technical team thinks.

The previous Long March 5 Yao 2 failed, and the rocket and satellite fell directly into the sea. The scientific research team "returned to zero" for two and a half years before the Long March 5 was launched again.

This delayed almost all major domestic space missions by two and a half years.

But in this life, with Lu Yun's participation, this kind of thing will never happen again.

Wu Di’s task was to accompany Lu Yun for a stroll in the Sixth Hospital first, and then hold an exchange meeting in the conference room in the afternoon.

He found out that Lu Yun was filming a video, so he took Lu Yun to film everywhere. Except for the confidential places, he was allowed to film everywhere, but the best place was the cafeteria.

It's noon now.

The two of them ate and chatted, and Lu Yun also asked about some non-confidential things.

"...After I finish the Long March 5 project, I'll be participating in the research and development of a new type of rocket," Wu Di said excitedly. "The new rocket model is confidential, and I don't know much about it."

"All I can say is that it's a large rocket with a takeoff mass of over 2000 tons. You know, after our country completes its unmanned lunar exploration project, we're going to do manned lunar exploration. A rocket of this level will definitely..."

Lu Yun did know that the rocket Wu Di was going to make was basically the one that would later be named "Long March 10".

It is a large rocket upgraded based on the Long March 5 technology, mainly used for launching a new generation of manned spacecraft and manned lunar missions.

Lu Yun had to get involved in the manned lunar mission, but before that, he had to set up his own private aerospace company, so he asked about this matter again.

"...The domestic private aerospace industry is developing rapidly. Several companies are poaching people from various research institutes. Someone from our Sixth Academy has been poached."

"But they're also not stable internally. I heard there's a disagreement within the largest company, Deep Blue Arrow Aerospace."

"Because solid rockets are developing smoothly, the voice of people working on solid rockets has overshadowed that of liquid rockets. One of our seniors is working on liquid rockets, and he's said to be planning to quit and do it himself..."

Lu Yun was stunned when he heard this, and quickly asked: "Is that senior called Yu Xingchen?"

"Hey, you know that too?"

"know a little……"

Lu Yun didn't expect that the world line would end so inadvertently, and Yu Xingchen still had to leave the Deep Blue Arrow.

Wu Di looked at the pensive Lu Yun and said with a smile, "You are now considered a star in the aerospace industry. I guess if Senior Yu really succeeds, he will probably look for you to attract investment."

"But with your aerospace talent, being an entertainment star is a bit of a waste. I feel that if you continue your studies, you might become a big shot like a chief engineer or an academician in the future."

"Of course, the private space industry is also developing very rapidly, and there is great potential for future development. It is said that the future manned lunar landing project will require cooperation between the national team and the private space industry..."
