Chapter 79: Linear Algebra
On June 28th, the B-class base was completed, and the engineering team from the mysterious force of the system disappeared after acceptance, leaving the engineers sent to receive and carry out a small part of the transformation.
On July 22, more than 100 employees of the original C-level base and the same number of newly recruited apprentices have entered their posts and put some of the equipment into working condition.
When Lin Ju arrived, the wasteland he had seen at the end of last year had disappeared completely, replaced by a huge aerospace manufacturing base with 5,000 acres of factory buildings, complete facilities, and two runways.
Even if we get all the people who can be poached by the cooperative universities to work, the current number of people in the B-level base cannot reach 300, and we need to expand desperately.
At present, the only part that is in operation is the high-altitude test bench of the engine test department, an assembly line and an automatic production line for silicon carbide chips, and it is expected that more than 25% of the equipment and machines will be put into operation next month.
Lin Ju has the illusion that a snake swallows an elephant and can't eat it, because as long as the entire production force of this base is launched, Xinyuan-2 can produce four heavy-duty carrier rockets at the same time, with a manufacturing cycle of 50 days, and an average of less than half a month.
According to the factory signs, he found a huge and advanced aero engine test bench, and Lin Ju found that work was already underway here.
A small bypass ratio, at first glance, is the XW-9 high-thrust turbofan engine air intake connected to the wind tunnel simulating high-altitude high-speed air flow, the tail nozzle converges, spewing out a long blue tail flame.
The XW-9 has undergone very little changes to the jet part of its original WCR-9 combo engine, so in the test data that Lin Ju saw from the test bench, the performance was completely in line with expectations.
In order to adapt to the high-altitude and high-speed environment, the bypass ratio of the XW-9 is only an astonishing 0.29, and even the bypass ratio of the F119 engine used in the F22 is about 0.34.
Even with such a small bypass ratio, the XW-9 still achieves the maximum output of 14.4 tons of thrust in the afterburner state, although it is not the highest in the world, but this small size and the advantage of adapting to high speed are unique.
When the aircraft is flying above 28,000 meters, thrust is no longer the most influential factor, but the risk of aerodynamic drag and lean air causing the engine to surge, reduce output power and even stop.
The XW-9 is best used for aircraft that fly high altitudes and speeds for long periods of time, such as supersonic airliners, supersonic bombers or medium interceptors.
As for the XW-10 that increased the bypass ratio to enhance the non-afterburner thrust, there are too many changes, and it is still in the design stage, so let's wait for the team to get familiar with the XW-9.
Leaving the Aviation Department, Lin Ju continued to rotate around the base, and when he arrived at the runway, he saw a row of things on the tarmac that were very discordant with the building:
A line of wheeled tractors, crawler tractors, cotton combine harvesters, cabbage harvesters, corn harvesters and other large agricultural machinery is neatly parked on the tarmac.
Seeing that there were his own employees there, Lin Ju hurriedly drove over and asked what was going on.
"Boss, it turned out that there was a backlog of agricultural machinery and accessories before the upgrading of the tractor factory, and then it was piled up in the open air and no one cared about it, and then we repaired these agricultural machinery, and the accessories were assembled and put together almost ten units, and the small place over there was transported over."
"What else do we need this for? What ministry are you? โ
Lin Ju was confused, and when he asked these people, they were actually working on the XW151 intelligent driving system with Xin'an, and they saw that the agricultural machinery actually wanted to make an intelligent agricultural machinery by the way.
Don't look at the difference between the tractor and the car working site, but it is much simpler to do intelligent and unmanned agricultural machinery than a car, and the biggest site changes and base station problems are much easier, which is an unimportant branch.
Perhaps to be nostalgic for the past, Lin Ju also climbed up to try a wheeled tractor, and then grabbed the gear handle and interior trim processed from rocket titanium alloy scraps and was speechless for a while.
Forget it, if you have money, you can make it willfully.

At 10 o'clock in the morning of the 23rd, the second live broadcast of Progress in space, the first lecture was officially launched.
The last time Huaguo taught in space was the Tiangong-1 mission in 2013, which was watched by more than 80,000 schools and nearly 60 million primary and secondary school students across the country, causing a huge response.
Although there was a big response this time, it was far from the spectacular spectacle of 60 million students.
Because Zhou Rui is talking about mathematics...... Linear algebra.
Yesterday's live broadcast was a small space experiment for all ages, drinking water balloons floating in the air, observing the spinning top in weightlessness, and showing bean sprouts that have just broken ground in space.
There is a live broadcast on campus, but there is still only a majority of primary and secondary schools that cooperate with the Shuchuan Education Department, and the effect is still very good.
The next day, it was a live webcast for all colleges and universities, Zhou Rui originally wanted to talk about the old bank sensors, but last night I heard that there was a large number of online agents in the department, so he decided to awaken everyone's enthusiasm for learning mathematics in this unique way.
The ground center said that it didn't matter, anyway, they were not the National Space Administration, and there were no rules and regulations for the astronauts' actions.
So after seeing the live broadcast screen in the Southern Institute of Machinery and many universities, I saw Zhou Rui, who had a kind face, and led the trio to introduce themselves first, and then Deng Lei and Zhao Xiaowen grabbed a whiteboard together and propped themselves up behind Zhou Rui.
Zhou Rui picked up the pen and wrote down the three words "First Lecture":
"Hello everyone, today's space lecture content is: Linear Algebra Lecture 1, Determinant.
The determinant is a very important concept in the ......"
"Ahem, ahem, ahem!"
In front of countless computer screens, students who have just been tortured by mathematics feel respiratory arrest and their eyes go black.
Before the broadcast, everyone thought that the live broadcast of space was interesting, and there would definitely be a lot of novel experiments and unique physical phenomena, and the results were:
The floating college teacher is sideways, talking about linear algebra and dangling at the same time, holding himself up on the bulkhead from time to time?
How can there be a feeling that the icons of old TVs with no signal are wandering around in full screen?
Although the live broadcast content made countless people drowsy after listening to it, under the blessing of the BUFF of space teaching, few people were willing not to watch it, and they just watched the two-hour non-stop online live class.
When Zhou Rui finished the live broadcast, he was very happy when he learned from the feedback from the ground that the number of viewers had not changed much, and he felt that his teaching method was novel and effective.
"Xiao Zhao, it's better to give a lecture in tomorrow's live broadcast, you come to the second chapter, I'm not familiar with the rest of it."
"Teacher Zhou, isn't this very good?"
"You have to believe in the experience of the old teachers! Let's hurry up and finish the experiment, there are a few culture media that seem to be a little problematic, leave more time to prepare for class before going to bed, and look at these years, the quality of students is not as good as one session, how can you contribute to the country in this way? โ
"Hey...... In that case, it is also so. โ
โโฆโฆโ
Commander Deng Lei had no interest in discussing how to persecute the fragile minds of college students, so he just floated to the porthole at the front of the nose of the plane, picked up the camera and kept taking pictures of the starry sky and the earth.
There is no exit link for this mission, but the extravehicular spacesuit is ready, and the next time you fly Unity, you will be able to get out of the capsule.
It was then that he truly experienced the magical feeling of being wrapped in darkness and suspended in space: this was told to him by astronauts who had already been out of the capsule.
But what they don't know is that a screenshot from the live broadcast has begun to spread on the Internet at a rapid pace.
Searching for the keyword Huaguo Space Class on YouTube, the video that is now ranked first has been played more than 4 million times, and it has only been released for less than 7 hours.
The cover is the most hilarious, Zhou Rui and Zhao Xiaowen are around the whiteboard one by one, on which is the painful linear algebra of college students all over the world, and the commander Deng Lei is holding plastic black tea, silently hiding in the cab to observe the starry sky.
The title of the cover reads: "The most boring space lesson ever." โ
The 2013 space lecture not only caused a sensation in China, but also created a large area of "demolition, demolition, and demolition" in the aerospace section of the Internet.
Although both Aramco and the former alliance sent people into space decades ago, broadcast the first spacewalk, and built a large space station, the world was limited by the fact that there was no Internet at that time, and the quality of TV broadcasts was not good, so the image for the new generation was not profound.
Therefore, on the contrary, China's aerospace industry has attracted a lot of attention, and the wall in 2015 is not so strict, and there are still a lot of exchanges.
After the Lin Ju rocket was launched, he liked to flip over the oil pipe and the little blue bird to see what these foreigners thought.
"The Space Shuttle is unreliable, and the Gaganyan program will be implemented next year, and our spacecraft will not only be more advanced, but will also take on the mission of transporting astronauts from the ISS."
This is the first high-praise comment that Lin Ju has seen, take a closer look, it's India, it's okay.
The Gaganyan plan was proposed to be implemented in the 70s, and there was no shadow for 50 years before Lin Ju crossed, indicating that the implementation next year would be the same as the bombardment 20 and flying tomorrow, which was all an illusion.
Let's look at the next one:
"Rough ใช Huaguo made ใงใ, H2A ใฏใใๅผทๅใงใ (Inferior Huaguo knockoff, not as good as a powerful H2A rocket)"
Well, it seems that Fukushima has eaten too much seafood and has a good life, and from 2013 to now, nuclear wastewater has been enough to mutate organisms.
No, the nuclear sewage has not yet been discharged into the sea.
Lin Ju wrote down a memorandum to stop the discharge of nuclear wastewater, and decided to find a way to stop it in the future, if the Ministry of Foreign Affairs dared to say that if it was discharged into the sea, the rocket would fail to launch and fall eastward.
"H1 plagiarized Aramco's space plane! The Progressive is a clumsy imitation of the Progressive Brand, a knockoff made from knock-off parts! โ
"The Hsiung Feng Missile is not the first in the world, and the mainland enterprises are stronger than us"
"Love comes from Tanzania, can China send African astronauts into space?"
"Stealing ex-alliance technology, ***"
"I don't want to read math at all, why don't silkworms spin silk?"
Most of the rest of the comments are demons dancing, and a few are interesting, in fact, many of Lin Ju on YouTube can be understood without translation, and the traditional Chinese comments under this kind of video are the most, but they are the most boring.
Let's take a look at the little blue bird, Ma Yilong's latest news The first one below is the dragon spaceship that mocks him, Lin Ju thought about it and gave Ma Yilong a thumbs up, and commented in trumpet English:
"Come on, the Dragon spaceship is better than the H1, you must stick to it."
A few hours later, Lin Ju landed on the little blue bird again and actually found that Ma Yilong replied to him, a simple thank you and an emoji.
Take a screenshot, save it for later, and take it out when you duel with the old horse octagon cage to make him laugh!
