This star is going to the moon

Chapter 47 Making Up for the Regrets of Chang'e

When Lu Yun said he was busy, he was not just talking, he was really busy.

He spends most of his time on the crew, but most of the time he is not filming, but waiting to film.

Because for the sake of the overall film effect, Lu Yun gave the "protagonist time" that should have been concentrated on him to other people, so that they could shoot more coherently and smoothly.

His strength is too strong and he can cooperate with them at any time, so he needs to be waiting on the crew at any time.

However, Lu Yun was not idle at all while waiting. He was basically looking up information and writing papers.

Those papers were published one after another, and each one was more critical than the last.

So it is not surprising that the Long March 5 scientific research team saw and studied his paper.

Lu Yun did not write his paper aimlessly, but to resonate with the technology of Wanhu Rocket.

For example, the rocket body weight reduction technology used in the Long March 5 Yao 3 rocket.

In fact, Lu Yun has already started applying for patents through the company's channels, including the rocket body weight reduction technology of Wanhu rocket.

Every launch vehicle has a load factor. The larger the value, the more payload can be sent into space with the same unit of fuel.

For example, the load factor of the Falcon 4.15 is 2.9%, while the load factor of the Long March is about %.

There are many reasons why the Long March 5's load factor is relatively low. The main reason is that the engine is not advanced enough, and the other is that there are too many safety redundancies, which result in too much dead weight of the rocket body, dragging down its carrying capacity.

If we ignore other factors and just do a rough numerical calculation, if the Long March 4.15 also has a load factor of 36%, then it can carry 25 tons of cargo into space, instead of the actual 32 tons and another theoretical tons.

The Wanhu rocket uses new technologies to reduce the weight of the rocket body, and with a more advanced engine, its design load factor reaches about 4%.

This still requires Lu Yun to quickly build the Wanhu rocket based on the current domestic aerospace technology.

Otherwise, if he were to study for a few more years, he could make the rocket lighter, increase the efficiency of the engine, and increase the load factor.

However, even such "general" rocket body weight reduction technology cannot be used on the Long March 5. Not to mention using it directly, even if it is modified, it cannot be used.

First, the bundled type and the bare rod type have different configurations and cannot be used indiscriminately.

Second, the Long March 5 is already a finished rocket and cannot be upgraded or modified drastically.

Third, it also shoulders many important tasks and cannot increase risks unnecessarily.

Therefore, the Long March 5 scientific research team can only start from the paper and then develop a technology suitable for the Long March 5 to reduce some of the small weight in the corners.

Lu Yun's various aerospace projects all started from design drawings, so there was no need to be so cautious. So he immediately started a video and told his silly roommates who had been admitted to graduate school about the lunar rover.

"what?!"

"You accepted a mission to develop a lunar rover that will actually fly to the moon?"

"Fuck!"

My roommates are so jealous that they are unrecognizable!
They all studied in the aerospace system, and each followed a mentor who was engaged in aerospace research, and worked hard for their mentors day and night, but none of them had participated in such a lunar exploration mission.

Not to mention lunar exploration, there has not even been a mission to enter orbit. At most, it has participated in some model missions or launched a sounding rocket.

It turns out that Lu Yun, the undergraduate who wanted to be a star, actually got a real lunar rover mission!
Oh, Lu Yun started his own aerospace company and published a lot of papers that even their mentors were amazed by. That’s fine.

Even their instructor would often look at them and ask, "Hey, by the way, aren't you Lu Yun's roommate? Why are you so... um, not trying to take advantage of his talent?"

"..."

What can they say? Are they saying that everyone was the same during undergraduate studies, and Lu Yun suddenly became smart after graduation?
However, they were quite happy with Lu Yun's current state of "not forgetting each other even when they are rich and powerful". They had made a fortune with the powered exoskeleton props before, and now he was leading them to develop a real lunar rover...

This isn't a roommate, this is a godfather!

Moreover, after Lu Yun talked about his "all-commercial parts lunar rover plan", his roommates were not surprised, but became even more excited.

Because they had all read Lu Yun's paper and knew what Lu Yun was verifying.

This is no less important than the topic their supervisor is working on!

The most important thing is that they can't get involved in the tutor's major projects, but they are involved in Lu Yun's matter throughout the whole process!

"I have been wandering for half my life. If Brother Yun doesn't abandon me, I am willing to be your adoptive father!"

"Godfather, just tell me what to do!" "That's right, Godfather, please give the order!"

"loyalty!"

"..."

Lu Yun looked at the three excited Huskies in the video speechlessly and said, "Although I already have a plan in mind, I still need to study the specifics carefully, so you'll have to wait a few days."

"..."

"Gan!"

"It's too early!"

"Give me back my dignity..."

Lu Yun no longer paid attention to these idiots, turned off the video and started designing the car.

The reason why the company’s people are not used is because the project is not big and there is no need to waste the company’s employees’ time.

Lu Yun did have a plan in mind, because Chang'e 6 in the previous life had a similar car.

It was originally intended to be a counterweight for Chang'e 5, which followed Chang'e , but scientists felt that simply using a piece of iron was too much of a waste, so they developed a mini lunar rover weighing about kilograms.

Even the original name of this car was "counterweight car", and it was later changed to "Golden Toad".

It is also in the same series as "Chang'e" and "Yutu".

It is less than 50 cm long and less than 30 cm wide, but the diameter of the four wheels is close to 30 cm. It looks like a rectangular box toy car with no sense of design.

Its greatest achievement is capturing the heroic image of Chang'e-6 standing on the back of the moon.

Against the dark background of the universe, the long robotic arm of Chang'e-6 shoveling lunar soil and the unfolded national flag are clearly visible above the dark gray lunar soil.

You should know that both the Chang'e 3 and Chang'e 4 missions carried serious lunar rovers, so they also had similar lunar rovers to take photos.

However, Chang'e 5 does not have a lunar rover, so there are no similar photos, which is a regret for many people.

The same thing happened to Lu Yun in the previous life.

I never thought that I would be able to make up for this regret in this life.

“It’s so nice to be reborn~”

Lu Yun is not worried about being sued for plagiarism by the Chang'e-6 project team in this life, because even though Chang'e-6 has been built as a backup for Chang'e-5, its degree of completion is actually not as high as Chang'e-5, and the plan for the counterweight vehicle has not yet been proposed.

The world line in this life has changed. The Long March 5 Yao 3 uses new technology to increase the lunar payload by dozens of kilograms, allowing Chang'e 5 to have a small vehicle. So when Chang'e 6 is launched later, it is hard to say to what extent China's lunar carrying capacity will develop.

If everything goes well, Lu Yun also wants to build a bigger car for Chang'e 6.

However, Lu Yun did not intend to copy the "Golden Toad" car exactly, because the original car only had solar panels on one side, and as a result, it fell upside down when it was released and could only operate for dozens of minutes using its own power.

So Roadun wants to put solar panels on both sides so that it can charge in the sun no matter which side it touches the ground.

He wants to let the car race around the Chang'e 5 lander.

After all, don't even think about putting any scientific research equipment in its 5-kilogram body. It's basically just a camera on wheels, so there's no need to take a step and stop for ten minutes to do research like a regular lunar rover. All you need to do is expand the mileage of the domestically produced lunar rover.

The defunct Yutu lunar rover only traveled more than 100 meters, and the future Yutu-1000 rover will take several years to travel 1000 meters while conducting research. Therefore, Lu Yun’s plan is to let the rover run meters a day, run as much as possible during the more than ten days of lunar day, and then photograph the Chang'e lander assembly from various angles.

When a goose passes by, it leaves a sound; when an object passes by, it leaves a trace. It is certain that Chang'e 5 will leave more impact!

"This little car is so powerful, what should I name it?"

"Cyclonus One?"

"Uh, that's the name of a nuclear weapon..."

While Lu Yun was busy, Liu Chun sent a message.

"There's news about 'The Longest Day in Chang'an' that you asked me to look out for, but we don't need to contact them ourselves. They've sent you an audition invitation directly..."
