The engine research and development team of the Chiang Mai branch of Aoba Automobile also tested new materials to make micro gas turbines.

In fact, the application of micro gas turbines in automobiles still faces some problems.

For example, the low thermal efficiency in the low-speed idle stage is too noisy and the manufacturing cost is too high.

But in the final analysis, these problems are actually two problems, ideas and materials.

The engine development team of Aoba Automobile Company did not use a micro gas turbine as a direct power, but adopted a hybrid idea.

The gas turbine is directly used as the direct power at high speed, and the electric is changed to electric at the medium and low speed, while maintaining the high-speed operation of the gas turbine, driving the micro generator to generate electricity and charging the lead-acid battery.

What lithium batteries, solid-state batteries, ternary composite batteries, etc., there is no need at all, safe and cheap lead-acid batteries are king.

In order to match lead-acid batteries, Aoba Automobile also opened a lead-acid battery factory, specializing in the production of lead-acid batteries used in automobiles, and sulfur dioxide purifiers are used to eliminate sulfur dioxide emitted by lead-acid batteries.

The noise problem of gas turbines can actually be reduced by design, as well as equipped with a soundproof lamination.

Finally, the thermal efficiency of micro gas turbines is not high, in fact, it is related to the inability to carry out multi-stage recycling of waste heat, which is the advantage of large gas turbines.

Implementing multi-stage thermal cycling in a micro gas turbine system can lead to skyrocketing costs.

So how does Aoba Motors solve this problem?

It comes down to the material.

Since the thermal efficiency of a single-stage cycle is not high, and the complexity and cost of a multi-stage cycle can be caused by the system, why not increase the pressure and speed?

Just like the supercritical power generation technology of thermal power plants.

With the support of the materials behind Homo sapiens, Aoba Automobile is taking such a technical route.

Increasing the combustion chamber pressure of the gas turbine increases the air intake, which in turn increases the impeller speed to 35,000 revolutions per minute.

This increase in size can further reduce the size of the micro gas turbine.

After all, the improvement of thermal efficiency also means that the unit power has increased, and the power consumption of the vehicle has been fixed in a range, so the size of the new micro gas turbine will inevitably be further reduced to supply the same power.

Another benefit of the smaller size is that the noise level will also be reduced.

Aoba Motor's gas turbine technology route is a hybrid route that is equipped with various new technologies.

Using the high thermal efficiency of the gas turbine in high-speed operation, the lead-acid battery is charged, and the lead-acid battery on board does not need much, and it is enough to run 50 kilometers at a time.

After all, this is a hybrid power, which can be charged anytime and anywhere, and equipping a large-capacity battery is a waste of resources.

……

Wu Haishen, the manager of the branch, listened to the reports of the engine R&D team, transmission R&D team and transmission system R&D team.

He put down the documents in his hand and raised his glasses: "In other words, at present, our various components are basically up to standard?" ”

"Yes, we have no problems with the engine."

"All five transmissions can also be put into use." Guan Jianzhi asked with some hesitation: "Manager Wu, will the supply cost of these parts be too high?" ”

Wu Haishen took out another document and flipped through the parts quotation on it: "No!" Overall costs have also dropped by about 37%. ”

"What?" Guan Jianzhi had a ghostly expression.

Immediately, the leaders of other projects also started to talk.

Apparently they thought that the parts suppliers might be playing the shoddy trick of cheating orders with low-priced, high-quality samples and then reducing supply.

After listening to everyone's discussions, Wu Haishen shook his head: "Don't worry!" No one dares to play tricks on such a thing. ”

As the manager of the spider web, Wu Haishen can know that Sea Snail New Materials Company is a brother company and is part of Homo sapiens.

The reason why we can supply high-quality parts at low prices is that on the one hand, the Aoba Group is its own people, and on the other hand, Sea Snail will not lose money.

After all, compared with traditional smelting, casting, and subtractive processing, the new materials manufactured by biosynthesis technology not only reduce the links, but also reduce the production cost by a large margin.

This cost advantage, of course, should be exploited internally.

If it is supplied to outsiders, the price will definitely be higher than similar parts on the market.

Hearing Wu Hai's assurance, although Guan Jianzhi and others didn't believe it in their hearts, they still didn't dare to ask questions openly, anyway, the production line must do quality inspection.

In their hearts, they just want the parts supplier to have a little conscience, so that everyone can't get off the stage in the end.

After an internal meeting, the Chiang Mai branch of Aoba Automobile began to enter full mass production.

……

At this time, Chiang Mai Province has almost become a construction site.

Six large automobile factories, several motorcycle factories, and a large number of supporting factories need hundreds of thousands of industrial workers.

Siam's population is only 66.17 million, and there is obviously a huge gap in the labor demand of hundreds of thousands of industrial workers.

After all, Siam was a predominantly agricultural area before, although there was 12 years of compulsory education, and the internal education level was relatively good, but it was generally at the high school level, and only a small number of college students.

In addition, Siam advocates a Western-style education model and does not focus on science and engineering.

Industrial workers not only need a certain level of education, but also college students and college students in science and engineering.

It is obviously difficult for some strongmen to get Western-educated college students to become industrial workers, and unless the other party is desperate, they would rather go to a foreign company or take the public examination than become an industrial worker.

Therefore, Homo sapiens still needs to find a way to solve this problem on its own.

The first construction company of the Chiang Mai Group.

The company contracted the construction of Chiang Mai Group's Glory Automobile Plant, and the company recruited a large number of young migrant workers.

Construction workers are divided into squads, squadrons, and brigades, and are closely managed internally.

Many squad leaders, squadron leaders, etc., are actually retired from the Thai army, and these people have been rebuilt, scum has become soldiers, and those with improvement value have become new humans.

Ishiyama Samuang is a retired soldier who was recruited as a new human because he had no bad deeds, and was trained at the Chiang Mai Vocational Training School for more than a month before becoming a squadron leader in a construction company.

In order to adapt to the interpersonal relationships within the company, he also gave a Chinese name: Meng Shi.

At this time, he was checking the progress of the project, and suddenly the walkie-talkie rang:

"All squadron leaders and above, please come to the manager's office for a meeting within half an hour......

After three times in a row, Meng Shi shouted to several squad leaders: "Do a good job, don't be lazy." ”

"Got it!"

"Head, don't worry!"

Several squad leaders hurriedly replied.

For Meng Shi, whether it is an ordinary construction worker or a team leader, they are actually both respectful and afraid of him.

The main thing is that his style is too decent, not at all like what he came out of the Thai army.

Meng Shi ignored his subordinates and hurried to the office where the meeting was held.

A dozen squadron leaders and several group leaders, plus several department heads, arrived at the office one after another.

The manager is Wu Xinhe, who came from Honsavady, and when he saw that everyone was gathered, he went straight to the point:

"You have to be a little busier in the next step, the company has a plan to unfold, and you need your cooperation."

"Manager Wu, what's the plan?" Captain Bakun asked.

"See for yourselves! One serving per person. After Wu Xinhe finished speaking, he sent a large number of documents to everyone present.

Meng Shi got the document and couldn't wait to open it.

This is a plan for the training of industrial workers, the core of which is very simple, requiring each construction team to form a study class, select the part of the construction workers who are willing to learn and change jobs, and then conduct a comprehensive training for these people.

The training time is a night school model, and the teachers in charge of training are new people within the company, and a group of engineers and technicians are also dispatched by the automobile factory as temporary training teachers.

As new human beings, although Meng Shi and others have only gone through more than a month of training, and then learned some knowledge independently through their free time, plus the assistance of biochips, in fact, their cultural level is not bad.

"Do you want to graduate from high school?" Meng Shi frowned.

Wu Xinhe smiled and shook his head: "Otherwise? Do you think those college students will come to the assembly line? ”

The others immediately reacted.

They are all from the past, and there are many college students in Siam who graduate every year, and the problem is that the elite of these people have already gone to Sing Dao, Europe and the United States.

The remaining batch is left in the big cities.

Although Chiang Mai is also the second largest city, the problem is that these university students generally want to work in the fields of finance, management, IT, pharmaceuticals, design, education, and healthcare.

For the hard and tiring construction, machinery, metallurgy, etc., unless it is a high salary, they will not consider it.

Homo sapiens companies want to make money, not to distribute benefits, so cultivating talents by themselves is the best choice at present.

Its various construction companies are screening construction workers who are willing to endure hardships and stand hard work, and then opening internal night schools and crash courses.

The entire automobile industry in Chiang Mai Province, the hundreds of thousands of industrial workers needed in the future, can only be trained from these high school students in their teens and twenties.

Fortunately, Siam is doing well in terms of basic education, and there are quite a lot of unemployed people in the interior, otherwise there would not be such a developed gray entertainment industry.

Especially graduates with high Chinese proficiency, they are the most embarrassing group in Siam, with a little culture and not enough jobs.

If it's rural, it's fine, but it's a big deal to go home and farm.

Those high school graduates born in the city can only roll up in the city, or give up their dignity and sell their bodies.

As a result, Chiang Mai Group's construction company was able to recruit a large number of young high school graduates as construction workers.

Now it is to open another upward channel for them, as long as they are willing to learn and hope to change the status quo, it is also a good way to become industrial workers.
