PS: As usual!
“I wonder what this July Flower’s robot design looks like?”
"It feels like a friend I follow goes on a trip and posts on Moments every day, but the place he travels to is a bit far away."
"Haha, I feel the same way."
"This design must be kept secret, right?"
"That's for sure. July Flower's rocket technology is good, and this robot technology is also very good!"
"If this robot can be brought back, its research value will be very high."
He Gui looked at the comments on the Internet and didn't know what to say, but when it comes to the design of the July Flower lunar exploration robot, it was done very well in 2009.
Sometimes it's strange, just like some places that collect scrap iron. If you look at the old steel bars from the last century, they are still in good condition. On the contrary, some used scrap products on construction sites are found to be more rusty than the old steel bars.
Just like the old-fashioned electric fans in the past, the motor can be used for decades without any problem, but now it can no longer be used for three to five years. Of course, the technology is more advanced now, and all the parts inside are guaranteed to have a good service life, such as the motor bearings and rotating
How many turns and how long the motor rotor runs can be easily achieved.
Even a pair of shoes can simulate walking for a certain number of steps... and it doesn't give you a chance to use them for a long time.
Besides, the July Flower lunar exploration robot was also designed based on the lunar environment. Although He Gui does not have this data in modern times, He Gui's own company had a lot of data in 2009.
"Has the robot's route been set in advance?" Ren Yingying asked.
"No, it is equipped with a small radar that can detect a distance of several meters. The radar can bypass the terrain if the detection is poor." He Gui said.
"We haven't done any on-site inspections, so the design route is not reliable. Besides, I originally only wanted the robot to work for a few days at most, and I didn't want to run it for a long time." He Gui was thinking about experiments when designing.
It carries more equipment, mainly to test the working environment of these equipment in harsh environments.
"You said if it breaks, can it be repaired?" Ren Yingying asked.
"It's better to launch it again."
"But I think most people should have a good impression of the July Flower. If it breaks down, we will send a robot to repair it. Will this make us more famous?" Ren Yingying explained with a smile.
He Gui thought to himself, this method is also possible, a lunar rescue?
"It's not technically difficult, but is it necessary?" He Gui touched his chin and asked.
"Of course, if it breaks, how about we hold a vote and see how many people like it. I'm afraid of the technical issues." Ren Yingying continued.
He Gui shook his head: "There is no technical problem."
"That's good." Ren Yingying nodded.
He Gui thought Ren Yingying's idea was a good one, so he said, "Let's wait until it breaks down. I'll study it first."
"Uh-huh."
He Gui continued to work in the workshop. The lunar exploration robot is actually modular in design, but if it needs to be rescued, it depends on where it is broken. Doesn't it mean that many parts have to be replaced?
Forget it, let the professionals in 2009 handle this solution and just copy it yourself.
Although some researchers there in 2009 did not understand a lunar exploration robot weighing more than 100 kilograms. Is it necessary to rescue it?
However, we still had to quickly complete the tasks assigned by our boss, so we simply designed a maintenance machine platform.
He Gui continued to work on the second-generation July Flower rocket in modern times. The second-generation rocket is larger, with a diameter of 3.5 meters, a thrust of 1,200 tons, and four nozzles.
It is divided into level one, level two, and level three. You can still return to level one.
This first stage has been used for a relatively long time and can be used as a booster in the third-generation July Flower rocket.
The reason why liquid rocket engines are used for launching rockets is because the thrust of liquid rockets can be adjusted. The same rocket can push 5 tons or 10 tons, and the fuel pump can adjust the thrust.
There is no way to adjust the solid rocket, the thrust is only that big.
Moreover, liquid rockets need to correct their direction when flying. The universal joints connected to the engine and engine below are not good for solid ones. The solid ones fly out with a swish, just like a cannonball.
Of course, it is technically possible to combine solid rocket thrusters with liquid rockets.
But why bother? Why bother? Solid rockets require gunpowder, which is more dangerous...
Although the structure of liquid rockets is complex, there is no danger during production. The gunpowder of solid rockets needs to be carved, so why don't you want to touch it anyway.
Liquid rockets are dangerous after the fuel is filled, but it has no effect on you. You are far away. Now rockets have self-destruct devices. Speaking of this, it is still because Mao Xiong tested the rocket and failed to launch it.
It seems that the top management has finished everything...
Making money is making money, but He Gui will not take risks...
This time the rocket motor will be larger and it will take longer. This time He Gui plans to use some stainless steel materials, such as some tanks, but there is one disadvantage.
When stainless steel explodes, it will burn incompletely, and the resulting debris will be everywhere. This is why most space stations and rockets are made of aluminum alloy, because it can burn in the atmosphere. Even most of our cargo spacecraft are the thickness of an egg shell.
Aluminum alloy.
In addition, aluminum alloy has another advantage, that is, it can be coated with heat-resistant coating on the outside. As for stainless steel, why not, because stainless steel itself has high resistance to hot spots.
But the cost of stainless steel is low...
"Forget it, it's all investors' money." He Gui shook his head and forget it. He might as well get some aluminum alloy. After all, this product is mature. What he wants is for the company to go public to make money and pretend to be B... Hehe.
There is no way to save anything on the engine. In fact, rocket engines reached their peak in the last century, such as the Saturn V engine and the Energia engine. So what is the combustion efficiency?
The increase is impossible.
It's nothing more than adding some combustion-supporting things to the fuel, but some of them are toxic and corrosive.
What He Gui uses is liquid oxygen kerosene, which contains not only liquid oxygen, kerosene, but also liquid hydrogen.
Of course, methane and the like are also used, and each company’s technical route is different.
He Gui concentrates on making engines in the workshop.
He Gui's school has already erected a dismantled rocket in the campus, with an inscription from a certain big shot on it... This is the Dinghai Shenzhen...
The school's aerospace department is also open, but the number of students admitted is not large. There are more than a dozen majors, and there are only about ten people in each major. Those who can get in here are reviewed and re-examined, and those who have relatives abroad are basically
It’s impossible to get admitted, let alone an international student or something.
This kind of students who are third-generation farmers are the easiest to pass the review. You must know that the reviewers will check everything. Some powerful people sometimes fall into this.
Of course, on the other hand, the higher-ups know He Gui’s technical strength and will not ignore the risk of technology leakage.
After leaving the workshop, Ren Yingying said: "The school called me and I want to have a few words when school starts. In addition, we also discuss the cooperation plan between the school and the July Flower Company."
"...Okay." He Gui looked at Ren Yingying and looked at him. It was probably that this girl wanted to move again in this corner of the mountain.
"Just one day, I'll have a meeting and you go hang out."
"For two days, I was also a professor at the school, and now I am the representative of July Flowers. Let's go shopping together the next day." Ren Yingying hugged He Gui's arm and looked at He Gui with a smile and said.
"Okay." He Gui nodded immediately.
He Gui murmured in his heart, if it weren't for the cooperation with the school... After all, if he cooperates with the school, someone will be responsible for some of the affairs of the July Flower Company. Besides, his July Flower Company will continue to grow, and the students he trains will also be his future employees.
After He Gui agreed, Ren Yingying went to reply.
The school has already made preparations. The school has not started yet. He Gui will not go there until after school starts. He Gui continues to make rocket engines in the workshop.
After the school received the news, it began to prepare. The school is now opening this major, which can be said to be using part of He Gui's influence.
A laboratory is being established at the school, and everything in it has been reviewed.
Some of the information He Gui sent last time was deducted a lot from the review above. Although in He Gui's opinion, the technology he provided was not very high, but for most countries in the world, aerospace has not yet started.
It is already considered a sensitive technology.
When He Gui reached 80% of the progress of making the rocket engine, that is, when assembly started, he went to Kyoto with Ren Yingying.
He Gui arrived at night, taking his own private plane. After arriving in Kyoto, Ren Yingying asked to live in the school. He Gui had dormitories in the school and was also allocated a house. Ren Yingying also had one...
There is no way, the soybean enterprise that He Gui cooperates with the school is making a lot of money. As the main contributor, He Gui doesn't get a house, so how can the rest of the people have the nerve to get a house?
"Teacher He, welcome." Generally in schools, everyone calls each other teacher. Of course, some professors are petty and would only be happy if you called them professor or something like that.
The top leader of the school and several people personally picked up He Gui at the school gate.
"Thank you, thank you, I'm bothering you so late." He Gui took Ren Yingying out of the car. Gao Zhong's car did not enter the school. He Gui did not advocate driving in the school.
He Gui's Baiyangdian University in 2009 all used uniform low-speed electric vehicles within the school. Anyone who drove a special car would get out immediately.
The situation inside the school is actually more complicated than on the road. At least there are red, yellow, green, etc. on the road. Moreover, the density of people in the school is greater, the greening is better, and the blind spots are very large.
"There, there, Teacher He, it's our honor to have you here." The top leader of the school is not low-level. He asked the people behind him about He Gui's affairs. The superiors told him not to ask so many questions. He knew more than he should know.
Yes, it’s not good for yourself.
At the level of the top leader of the school, it can be said that he can see most of the confidential documents. After being warned like this, he immediately knew that He Gui's identity was very deep, very deep... If he inquired more, he might be investigated...
"Hello, Teacher Ren." Ren Yingying is also a professor at the school, so the top leaders naturally know each other, although Ren Yingying rarely comes to class.
"Hello." The first and second leaders of the school took the school's car and then arrived at the place where He Gui lived.
"Teacher Ren's house is also here, and he is a neighbor to Teacher He." When we arrived at the place, we found that it was a small western-style building, and it looked like it had been recently built.
To be continued...
