Chapter 1373
Electric Train Successfully Developed, Level 4 Test Completed, Leader Teng Wants to Boa
Time is like a mudslide.
Even when it encountered obstacles like loose rocks, it still roared off in its intended direction.
The situation on the South Asian peninsula has undergone significant changes.
The Indians have lost a lot of territory and their resource supplies are starting to run out, so they are frequently asking the Russians and Americans for help.
Xiao Mei's family was already deeply mired in the monkey's family's mess, and the scale of their troubles was constantly expanding. They had no reason to help the Indian family.
As for the Russians, they're busy arm wrestling with the American family.
In the eyes of the Russians, the Indians were utterly hopeless and utterly hopeless.
Investing in such worthless investments yields no return, so I decisively chose to remain aloof and observe.
The Indians went around in circles, only to be turned away at every turn, and didn't receive any substantial assistance whatsoever.
These guys were desperate, and they came up with a crazy idea: they turned around and raided the neighboring Xiao Ba's house, trying to save face elsewhere. They even made a big show of it.
Unfortunately, they miscalculated.
The Ba family is no pushover.
During this period, Xiao Ba's family vigorously developed a motorcycle assault team.
Faced with the Indians' surprise attack, they were not intimidated at all and directly confronted them head-on, defeating the Indians soundly.
The Indians suffered a loss, so they should keep a low profile for a while.
But they actually formed a victory speech group and started going to other people's homes to tell them about their great victories.
If you didn't know better, you'd think they were the real winners.
Of course, this matter has little to do with Li Aiguo.
As long as Li Yunlong can steadily advance, any action taken by the Indians will only be a death throes.
Meanwhile, the construction of the P4 laboratory in the Gobi Desert in Northwest China is progressing smoothly.
When Wang Chenglai called Li Aiguo, he casually mentioned some exciting good news.
The Department of Chemistry at Beijing University has successfully developed bovine insulin!
This is the world's first time that a biologically active protein has been synthesized artificially!
They were able to achieve such a major breakthrough under such difficult research conditions and material circumstances.
Li Aiguo felt a deep and sincere respect for the senior members of the Chemistry Department in Beijing.
Bovine insulin is of great technological significance, serving as the foundation for recombinant human insulin.
Unfortunately, in Li Aiguo's memories of his previous life, these senior figures in the Chemistry Department of Beijing did not continue to explore this field in depth for various reasons.
Ultimately, this groundbreaking achievement, which was enough to change the history of human medicine, was surpassed by the "Hope City Lab" of the Little Beauty Medical Center.
Not only did they develop recombinant human insulin, but they also used it to develop a highly effective drug for treating diabetes, making a fortune.
It is important to know that diabetes was called "Xiao Ke Zheng" in ancient times, and it has always been a major problem in the medical field, with no way to cure it completely.
For large pharmaceutical companies, a disease that cannot be cured is a good disease.
Once this special drug is available, it will definitely be a super gold mine!
If the opportunity arises, I'd like to collaborate with the Chemistry Department in Beijing.
Thinking of this, Li Aiguo suddenly smiled.
He felt like he wanted to do everything.
There was no other way; as a time traveler, this era was a gold mine.
However, Li Aiguo also knew that one must eat one bite at a time and walk one step at a time.
Taking too big a step can easily lead to trouble.
No rush, take your time.
……
Monday was a clear, cloudless day with a gentle breeze.
Today is the day of the first test of the electric train.
As the chief designer, Li Aiguo got out of bed early in the morning.
As usual, he carried the enamel basin to the pool.
By this time, a number of neighbors who had gotten up early to wash up had already gathered around the pool.
Everyone was brushing their teeth and washing their faces while chatting about everyday things.
The courtyard house was filled with the vibrant atmosphere of daily life in the early morning.
"Patriotism, I'm thinking of having my second son sign up to work in a third-tier factory. What do you think?" Old Zhao from next door chimed in.
Since February, when the Third Front construction plan was officially launched, more and more young people in Beijing responded to the call and went to support the construction.
"This is great news!" Li Aiguo replied with a smile as he wrung out a towel.
He remembered the second son of the Zhao family. The boy wasn't a bad person at heart, but he spent his days loitering around on the streets.
If I could go to a third-tier factory to hone my skills, I might really be able to transform myself and make something of myself.
"Hey! Since even you, who is patriotic, say it's good, it must be true! I'm going back right now to drag that brat out of bed and make him go sign up right now!"
Upon hearing Li Aiguo's words, Old Zhao felt reassured and, without even brushing his teeth, grabbed the basin and rushed home.
Yi Zhonghai, who was not far away, witnessed the whole scene and felt quite uncomfortable.
You know, in the past, whenever anyone in this courtyard couldn't make up their mind about anything big or small, they would have to consult him, the old man.
He only needs to give a few pointers, and everyone is extremely grateful.
Now, things have gotten complicated; instead of him, people are looking for Li Aiguo.
Xu Damao squatted by the flower bed, brushing his teeth while speaking with a mischievous grin.
"Hey, old man, didn't you also clamor to go to a third-line factory to make your mark?"
Even after writing a blood oath, the factory still hasn't approved your application?
Could it be that they think you're too old and frail, and that you'd just be a freeloader if you went?
Xu Damao was deliberately bringing up a sore spot, and Yi Zhonghai was so angry that his lips trembled. He didn't even bother brushing his teeth and turned to leave.
"What does this have to do with you? Mind your own business!"
Yi Zhonghai gritted his teeth and cursed, then, without even washing his face, picked up the washbasin and angrily turned and went back into the house.
Xu Damao watched Yi Zhonghai's dejected figure, curled his lip smugly, and turned to Li Aiguo.
"Patriotic brother, have you seen this? This old man is becoming less and less popular these days."
I think he won't be able to stay in this position for long!
Li Aiguo smiled but didn't respond. He brushed his teeth and turned to go back inside.
Li Aiguo had absolutely no interest in the position of an old man.
They spend all their time dealing with trivial and unimaginative matters. If they had the time, they would be better off developing more advanced technologies within the system.
Take a thousand steps back.
Even if you have free time, read more books and grind more points to prepare for dominating the server in the future.
Chen Xueru had already prepared breakfast, which was quite simple: a bowl of cornmeal porridge, a steamed bun, and a fried egg as a side dish.
After eating and drinking his fill, Li Aiguo did not go to the Changxindian Locomotive Factory first.
Instead, he went to the Qianmen Locomotive Depot for the weekly meeting.
The Qianmen Locomotive Depot has now expanded several times in size, transforming from a simple locomotive depot into a comprehensive factory.
In the conference room, leaders from various departments, including the passenger transport workshop, freight transport workshop, and maintenance workshop, gathered together.
Of course, Li Aiguo only listened without speaking. After the meeting ended, he would convey the spirit of the meeting to the researchers in the studio, and that would be the end of his job.
After doing all this, Li Aiguo arrived at the Changxindian Locomotive Factory.
At this time, a large crowd had already gathered around the experimental circular track of the locomotive factory.
Today's test has alarmed bigwigs from all sides.
Leaders from the Ministry of Railways, including Teng, leaders from several other ministries, leaders from the Beijing Railway Bureau, and leaders from the Changxindian Locomotive Factory.
Even Mr. Liu Guozhang, the representative of the subway, came over.
At this moment, everyone was marveling at the experimental circular track.
It's no wonder they lost their composure.
The electric train system in front of us is simply too amazing!
An electric train is not just an electric traction rail vehicle, but also includes the track line, trackside conductive rails, overhead contact line power supply, transformer equipment, and so on.
"This thing looks really weird."
"Yes, to be able to build such a tall overhead contact line, Comrade Li Aiguo is indeed a genius."
"The main thing is the design concept. Haven't you noticed that the electric train developed by Comrade Li Aiguo is, to some extent, very similar to the future development direction of electric trains predicted internationally?"
The one speaking was Chief Engineer Liao.
As the deputy chief commander of the electric train manufacturing project, he was responsible for introducing the technical details of the electric train to the leaders.
"Comrade Aiguo is here." Liu Guozhang waved to Li Aiguo as he approached.
"Everyone's waiting, so don't embarrass the teacher. But don't be nervous, this project is too advanced. Our requirements from the subway side are a bit excessive."
The meaning is quite clear: this electric train project was initiated by the Metro Group.
Even if there were problems with the experiment, the responsibility should lie with him, the person in charge of the subway.
"Haha, Comrade Guozhang, Comrade Guozhang, so many years have passed, but your fiercely protective temper hasn't changed at all!"
Upon seeing this, a leader from a nearby ministry couldn't help but make a joke.
Liu Guozhang stiffened his neck and retorted confidently, "Old Zhou, stop talking nonsense while you're standing there!"
"Put your hand on your heart and tell me, if you had a student like that under your supervision, wouldn't you protect him?"
“Uh…” The ministry leader, referred to as Lao Zhou, was immediately rendered speechless by the rebuttal.
Come to think of it, if he had a student like that, he'd be so happy he'd wake up in his sleep.
Leader Teng watched the group bickering with a smile, then strode forward and waved to Li Aiguo.
"Comrade Patriot, Lao Liu is right. When you get down to business, you're bound to fail sometimes. Come on, let's start the test!"
"Yes!" Li Aiguo knew that Leader Teng was decisive and efficient, so he did not waste any time and immediately asked Chief Engineer Liao to lead the technicians from Changxindian Locomotive Factory to begin the pre-test inspection.
Actually, this kind of check has been done several times, so naturally there are no problems.
"Ready, test begin!"
At Li Aiguo's command, the power company personnel responsible for operating the high-voltage electricity switched on the power.
However, the result was quite surprising.
The electric train on the track remained quietly parked there.
Apart from a faint, extremely slight humming sound of electricity coming from inside the carriage, the entire locomotive showed no signs of moving; not even a single wheel turned a millimeter.
Seeing this, the atmosphere at the scene suddenly became somewhat eerie.
At that time, some leaders who didn't understand technology couldn't help but mutter to themselves.
"What's going on? The power switch is on, why isn't the train moving at all?"
"Could we have messed it up? Which wire is connected incorrectly?"
"I knew it! This thing is too complicated; it's bound to malfunction..."
"Shut up, all of you! What nonsense are you spouting!"
Leader Teng suddenly turned his head, his sharp gaze sweeping over the gossiping leaders like a knife.
After reprimanding his subordinates, Leader Teng turned to Li Aiguo with a smile and said, "Aiguo, tell everyone, what exactly is going on here?"
Li Aiguo smiled faintly, showing no sign of panic.
"Sir, in order to ensure safety and fully test the electric train, we have designed a complete set of testing methods called the four-level test procedure."
As soon as Li Aiguo finished speaking, the eyes of the several railway experts present lit up and they all pricked up their ears.
It's important to understand that in this era, electric trains were still a novelty worldwide. Although a very few countries had begun experimenting with electric locomotives, they were mostly learning as they went, and hadn't yet developed a set of testing procedures.
Everyone was just blindly tinkering based on their past experience with steam locomotives. They would only learn lessons from accidents, and they were essentially using human lives and huge sums of money to experiment.
Li Aiguo was well aware of the dangers of electric locomotives, especially the tens of thousands of volts of high voltage; an accident would result in a tragedy of vehicle destruction and loss of life.
Therefore, he simply modified the four-stage test procedure from later generations and adopted it.
As all of you readers who participated in the development of the Harmony high-speed train know, the so-called Level 4 test is mainly divided into four stages.
The first stage is a static insulation test after power failure, which mainly checks high-voltage power components such as wiring, IGBT modules, motor windings, and bus capacitors.
Low-voltage no-load commissioning will only proceed after the first stage is completed.
This stage mainly tests whether the PWM waveform output and V/F curve are normal.
The third stage is the high-pressure windless load test.
The test was conducted using an empty vehicle. The pantograph was connected to the 25kV power frequency grid voltage, and the four-quadrant rectifier was put into operation.
Only after the first three stages went smoothly did I begin to oversee the ring road test drive.
After listening to the entire process, the accompanying experts nodded frequently.
"The four-level test designed by Comrade Aiguo is progressive and can both eliminate problems and obtain real data. It is rare."
"Yes, we are seriously underemphasizing testing work right now, and we haven't even formed a complete theory."
I think that even ordinary trains can be tested according to the same standards as Comrade Patriot's Level 4 test in the future.
When Liu Guozhang heard these veteran experts give such high praise to his student, his old face beamed with a radiant smile.
He looked at Li Aiguo with a proud expression: "Aiguo, did you hear what all the experts said?"
Those who are capable should do more!
Once our electric train test run is successfully completed, don't even think about slacking off.
"Hurry up and work overtime to compile the four-level testing standards for the compatibility of steam trains and diesel locomotives!"
"No problem, teacher! I guarantee I'll complete the task!"
This so-called "four-level testing standard" has been continuously developed and verified through countless practices over decades, and is therefore impeccable.
Li Aiguo agreed without hesitation.
As they were talking, the first phase of testing was completed.
"Report to the commander-in-chief, the static insulation test without power was successful!" a technician reported.
"Proceed to the second item immediately."
"Yes!"
The low-voltage no-load commissioning was particularly time-consuming; the first round of commissioning was still not finished by noon.
When the leaders of Changxindian Locomotive Factory saw this, they took the initiative to say, "Leader Teng, leaders, look, it's already midday and the sun is very strong."
We are truly honored that our leaders have taken time out of their busy schedules to visit our Changxindian Locomotive Factory and provide guidance today!
To reward everyone, I have already asked the factory canteen to prepare the most sumptuous meal in advance.
How about we... move to the cafeteria for a meal and rest for a bit?
There's no need to rush this test.
"No need to trouble yourself." Leader Teng refused without even thinking.
He glanced at the electric train that was being tested, and without turning his head, casually said, "Let's eat here! Have your canteen staff deliver the food directly to the testing site!"
When the leaders of Changxindian Locomotive Factory heard this, they were completely stunned.
This is a newly opened test site in the middle of nowhere!
Everywhere was covered in yellow dust, and a gust of wind could blow sand into your eyes.
Why should ministry leaders eat their meals in such a dilapidated place where there isn't even a stool?
If word gets out, people will think that the Changxindian Locomotive Factory is deliberately mistreating its leaders!
The factory manager, however, sensed something and winked at him: "The leaders are still concerned about the debugging, hurry up and go."
"Yes!"
Soon, the cook from the Changxindian Locomotive Factory canteen, along with several workers, delivered the meal to the testing site.
The meal was plentiful, including braised pork with vermicelli and white rice.
It tastes great too.
Li Aiguo finished a large bowl of rice; his appetite is considered small.
People in this era are capable and have a big appetite. A technician from Northeast China ate three large bowls of rice and finished a whole enamel basin of vegetables.
This technician has been working at the Changxindian Locomotive Factory for several months.
Li Aiguo felt it necessary to wait until the project was completed before allocating a batch of supplies to the locomotive factory.
cough cough.
The testing continued in the afternoon.
With a good start in the first phase, the subsequent tests seemed to go smoothly.
With the completion of the second and third phases of testing, we have finally reached the fourth phase.
The atmosphere at the scene became tense.
The electric train had stopped at the starting point of the loop line, and Chief Engineer Liao and his technicians conducted another inspection.
"Patriotism, no problem. We can start the mainline load test run. I have already transferred several train drivers from the Beijing Railway Bureau and given them advance training in driving electric trains."
"I'll go."
Li Aiguo waved to Chief Engineer Liao.
Just kidding, as a train driver, the world's first VVVF locomotive that I developed is about to undergo testing.
If he doesn't become the train driver, who will?!
Chief Engineer Liao's expression changed. Although the first three stages went smoothly, the fourth stage was no less dangerous.
In particular, this time a maximum speed test will be conducted, and trains derailing during high-speed loop tests is not a new phenomenon.
The Zhuzhou Locomotive Research Institute had to halt its electric train development due to such an accident.
"patriotic."
Chief Engineer Liao was about to offer further advice when a voice rang out.
"I'll accompany Comrade Patriot during the test!"
Everyone looked in the direction of the voice, and their expressions changed when they saw Leader Teng walk forward.
"Leader Teng, test driving is too dangerous."
"Haha, how dangerous is it compared to fighting the Japanese back then? Besides, if we ourselves don't dare to ride our own electric trains, how can we feel safe using them to transport passengers in the future?"
After saying that, Leader Teng patted Li Aiguo on the shoulder.
"I have faith in Comrade Patriot's technical skills!"
Hearing this, I recalled how, back then, when Leader Teng knew there were many times more enemies ahead, he still personally led the charge, and all the ministerial leaders knew they couldn't dissuade him.
Liu Guozhang did not expect that Leader Teng would take the lead and quietly pull Li Aiguo aside.
"Patriot, be careful during the test later."
"Don't worry, teacher, there won't be any problems." Li Aiguo nodded.
The VVVF locomotive was already very advanced in later generations, so Li Aiguo wasn't worried about safety at all.
“Aiguo, I’ll be the co-driver,” Old Zhang volunteered, stepping forward.
In the electric train research group, besides Chief Engineer Liao, Lao Zhang was the one who knew the most about electric trains.
Furthermore, he is primarily responsible for the power unit, so he can resolve any problems promptly.
Li Aiguo had worked with Lao Zhang several times before, and it had always been a very pleasant experience, so naturally he wouldn't refuse this time.
"Come on, let's get in the car."
Besides Leader Teng, Li Aiguo, Lao Zhang, and several technicians, experts from the Ministry of Railways also boarded the train.
These experts are responsible for accurately recording the entire test drive process, and this data will be discussed at a future meeting.
Leader Teng, being a veteran who had survived countless battles, showed no sign of worry after getting into the car. Instead, he enthusiastically toured the driver's cab.
"There's no furnace inside, so it's exceptionally clean. If this technology is widely adopted in the future, train drivers will be able to enjoy a better life."
"Yes, but something's still missing," Li Aiguo said while checking the dashboard.
"what?"
"Air conditioning is becoming increasingly common overseas; it's the kind of device that can cool you down."
Li Aiguo wiped the sweat from his forehead. It was already summer, and the front of the car had been parked under the scorching sun for most of the day, turning it into a sauna.
Leader Teng chuckled to himself.
There's no furnace inside; it's so much more advanced than before, and it even has air conditioning?
With such a large front end, what kind of air conditioner can power it?
Li Aiguo smiled and didn't explain further. In fact, he already had a complete plan in mind.
Air conditioning is a great way to beat the summer heat, so we should get it developed as a priority.
"Driver, everything's fine, we can set off now," Old Zhang said after completing the inspection.
"set off!"
Li Aiguo pressed the switch.
The high-voltage current silently travels along the overhead contact line and enters the power system through the high-voltage cable, and the train slowly begins to move.
"Look, the electric train is moving."
It really moved!
The audience erupted in enthusiastic applause.
Everyone knows that as long as the train can start, it means that the success is more than halfway there.
Chen Xingyi stood in the crowd, and the heart that had been hanging in his throat was finally half relieved. He casually picked two ears of corn and waved them in his hand.
Brother-in-law, you must come back safely.
Just as Li Aiguo was driving the electric train to begin testing, several large off-road vehicles roared along the road toward the Changxindian Locomotive Factory.
“Mr. Louis, the Changxindian Locomotive Factory is just ahead. It’s also our largest carriage manufacturing plant. The batch of carriages you ordered will be manufactured by this factory.”
In the back seat of the carriage, an official from the foreign trade department was speaking fluent French to a blond, blue-eyed Frenchman next to him.
Although he wore a professional smile, his heart was filled with helplessness.
The Frenchman sitting next to him, named Louis, was no ordinary person.
He was the chief engineer of the French state-owned railway company.
Everything was fine.
The chief engineer of the French national railway company insisted on visiting the factory where the carriages were manufactured.
Fortunately, the Changxindian Locomotive Factory was not a secret unit, and the foreign trade department, taking into account the fact that France had ordered more than 500 carriages this time, agreed to the order.
Chief Engineer Louis leaned back in his seat, listlessly gazing at the somewhat desolate scenery outside the car window, not holding high hopes for the visit.
In his view, even though the railway industry here has made great strides in recent years, it is still limited to the steam engine stage.
It would be good enough if they could even build a decent carriage.
There's really nothing noteworthy about this advanced technology.
However, just as the car was about to round a hill and approach the outskirts of the locomotive factory, Louis casually glanced at the distant plains.
Suddenly, his body stiffened abruptly, and his eyes widened instantly.
"My God! What...what is that?!"
"Huh? The design of that train... God, it doesn't have a chimney!"
And how could it be so fast? That's impossible!
