We have a lot of semiconductors in this era, and when it comes to this, we have to say Lin Daniu (Lan Ying. ）

This is a pioneer of semiconductors in our country, and in 1961, she presided over the research of open-door silicon monocrystalline furnaces.

In the spring of 1962, she stretched China's first dislocation-free silicon single crystal.

In October of the same year, she produced the first gallium arsenide sample in China.

In 1964, she manufactured China's first gallium arsenide diode.

And in this world, our logs, as well as mushroom technology, are funded by bangs, especially the simulated missiles that were lost in the early days, and the centrifuges and high-temperature resistant materials in the back.

With the development of log and mushroom technology, the art of anti-log and anti-mushroom technology has also been put on the agenda.

Therefore, at this time, our domestic electric scanning phased array radar technology is seven or eight years earlier than in history.

Historically, due to the strong wind, there have been discontinuities in many studies, and there have been constant substitutions.

At this time, there is a lot less wind, in fact, the wind is strong, often because there is no money to make trouble.

It's like in a family, if the family is poor, then the two will have a conflict over some small expenses.

But if the family is rich, there will be much less conflict in the family, and the wind will be much less, so a lot of research work can be continued.

Don't underestimate the change of people in the research work, which is a great delay in time, because everyone is in charge of the research work, and the direction of thinking is not the same, and there are some differences.

Historically, this has been the case with the study of fighter jets, where the progress of the research was interrupted due to the substitution of personnel in the middle of the process.

After Sun Aiguo reported to the leaders, the higher departments increased investment in this area of research, and the research equipment should be given to the research equipment, and the dealers who did not have it in China were entrusted to buy.

Among them, the semiconductor laboratory in charge of Lin Daniu also received a lot of funds.

The 4004, 4001, 4002, and 4003 chips bought and sent by Bang Hai are also being studied in various research institutes.

The semiconductor technology of our time can be said to be not inferior to foreign countries.

In fact, in many foreign high-tech projects, the Chinese occupy a pivotal position.

You must know that the chief designer of the militia logs, one of the world's three major logs, Dongfeng, militia, and poplar, is Lin Hua of Boeing, and the designer of F14, who is also surnamed Lu, and the F35B active phased array radar is said to be a female designer surnamed Xu.

Not to mention Qian Lao, one of the initiators of the famous Manhattan Project.

Of course, Liu Hai does not know the specific progress of these projects, and Liu Hai can also know from some public information that we are developing well in semiconductor technology.

The public news, of course, is the launch of satellites and launch vehicles.

To put it bluntly, a launch vehicle is a large liquid missile.

From the launch frequency and load of our launch vehicles, we can know that we are developing well in this regard.

Sun Aiguo has been a little uncomfortable recently, because since the leaders of the higher-level departments knew about the motorcycle factory and began to design and manufacture his own helicopters.

No matter which department they go to report to something, these leaders have to ask about the progress every once in a while.

But Sun Aiguo couldn't ask Liu Hai often, because Liu Hai was busy enough.

In terms of superyachts, the main design of the yacht has been completed, the keel has been laid, and the rest is the design of the interior decoration.

Bangs have to put energy on this side, because there are a lot of departments involved in decoration and decoration, and there are many materials needed in it.

There are also ordinary yacht workshops that have begun to be manufactured.

In addition, Liu Hai also came up with a manufacturing process for instant noodles, and the motorcycle factory opened another workshop and was experimenting, and Liu Hai occasionally had to go over for guidance.

Not to mention supercars, superbike sports cars.

In addition, he supervised two cartoons, and Sun Aiguo felt that his bangs were simply more than his own business.

Because Sun Aiguo felt that his management was relatively simple, he just needed to put the task below.

The management of bangs is more complicated, because it involves technology.

Sun Aiguo can't often ask about the progress of bangs, and as for the overall progress, others don't know.

Because now everyone only knows the drawings of the parts taken out by the bangs and the manufacturing process.

As for the overall part completion ratio, only the bangs know when to start assembling and when to start experimenting, and others don't know at all.

Liu Hai also has to design the whole helicopter, so every time the leader asks, Sun Aiguo can only play haha.

Bangs have an account in his heart, and the manufacturing of various parts of the turboshaft engine is quite smooth.

Make five of the same parts and assemble five turboshaft engines later.

One of them was used as a test run, as well as a life test.

The remaining bangs are ready to make two helicopters.

All the part drawings bangs are numbered, and then the manufactured parts are also numbered.

The first time a manufacturer comes into contact with these parts, the inevitable scrap rate is relatively high.

Ma Fuqiang began to feel that the scrap rate of parts in the factory was too high, and he was afraid that he would be held by the leaders.

Because in the diesel engine power workshop, once the scrap rate of some people's parts exceeds a certain amount, they will be called to a meeting by the leader.

And here Ma Fuqiang found that he is not afraid of parts manufacturing failure, every time he fails, as long as he finds out the reason for the failure, and then continues to remanufacture.

Ma Fuqiang's group, as long as there are scrap parts, everyone will gather together to find problems and discuss.

There are all kinds of things that everyone discusses, and at this time, Liu Gong will not point out where the mistakes are, and will let everyone make them again according to what they think is wrong.

Obviously, most of the questions raised are not the point.

In the end, everyone failed, and Liu Gong would stand up and point out where there was a problem.

At the beginning, Ma Fuqiang didn't understand, but later Ma Fuqiang found out that Liu Gong's approach made everyone have a better understanding of the manufacturing process and technology of parts.

Liu Hai has personally processed these parts, of course, he knows where it is easy to go wrong, and the reason why he doesn't say it first is to let everyone explore and discuss.

Liu Hai is ready to train these people into backbones, although these people do not understand the overall technology, but as long as they understand the parts manufacturing process.

It's terrible, especially at this time, but the wrong direction that these people sometimes put forward makes Liu Hai dumbfounded, because according to Liu Hai's own understanding, it is impossible to think in this direction.

But it is this wrong direction, and many people agree, so Liu Hai let everyone remake parts according to their own understanding.

When everyone fails, Liu Hai stands up and points out the right direction, so that everyone can easily solve problems when they are manufacturing in the future, especially when manufacturing in batches.

There is still a big gap between the current sample manufacturing and the subsequent batch manufacturing.

Liu Hai made a sample helicopter this time to improve the technical level of these people.

Strive to throw out the drawings themselves next time, and they will be able to manufacture the parts correctly.

Because it is foreseeable that it will become more and more difficult to manufacture equipment in the future.

Liu Hai is ready to train a group of technical backbones for the manufacture of aero engines.

It is enough not to ask these people to understand the design and principle of the entire engine, but to make these people able to manufacture individual parts according to the drawings.

Of course, these dozens of people are fortunate to have Li Dali and these people inside, and the people on the maintenance department have experience in manufacturing helicopters earlier.

In mid-April, Liu Hai saw that the manufacturing progress of the scrollshaft parts had been completed.

We are ready to start assembling the turboshaft engine, and the assembly of the turboshaft engine is also done by a special team.

The reason why the bangs are separated is actually for better management.

Because bangs can't require these workers to be able to make parts and components, and to be able to assemble them.

The requirements for others are too high, so Liu Hai selected a few top-notch technicians from these workers and began to lead them to assemble the finished product.

While others continue to manufacture components, there is no shortage of turboshaft engines behind them anyway.

Ma Fuqiang was successfully transferred from the parts manufacturing team to the assembly team.

There weren't a lot of people in the assembly group, only three people.

Ma Fuqiang counts one, Li Dali counts one, and there is Zhang Jianguo.

Because it doesn't take too many people to assemble this kind of engine, there are too many people, but there are many hands.

Moreover, this kind of turboshaft engine does not need to be manufactured on an assembly line, on the one hand, the demand is not so large, and on the other hand, it is not suitable for assembly line manufacturing.

"Today I will lead you to assemble the first turboshaft engine designed and manufactured by our factory."

"You don't need to know how a turboshaft engine works, you just need to know how to install every component correctly."

"The first turboshaft engine, I and Li Dali and I will assemble it first, Ma Fuqiang, you take the assembly manual, compare the assembly steps of me and Li Dali, Zhang Jianguo, you are responsible for handing the parts to the two of us on the side, and by the way, record according to my requirements." Bangs directly began to assign tasks.

Ma Fuqiang held a thick assembly manual, which had all the parts numbers and assembly steps, including how to assemble each part?

On the other side of Zhang Jianguo is the record responsibility card, and Li Dali and Liu Hai began to assemble it.

Bangs picked up a part and began to say the part number as well as the assembly method.

Li Dali started assembling right next to him, while Zhang Jianguo recorded the assembly time, assembler, and the number of assembled parts.

Ma Fuqiang was on the side to check the assembly manual.

Liu Hai really has less time to do it, and he is basically directing Li Dali what to do.

Li Dali has followed Liu Hai for so many years, but he still has a lot of deficiencies in aero engine expertise, but his simple hands-on ability is not bad at all.

As for the other members of the Maintenance Section, they also have important responsibilities in several other teams.

Because the parts are still being manufactured, there are maintenance department personnel in the backbone, so that other engineers can master the manufacturing technology as soon as possible.

For the first time, Ma Fuqiang knew that the turboshaft engine has so many doorways, so many parts and components assembled inside, and most of the parts have strict assembly requirements.

Step by step, it took four days for the turboshaft engine to be assembled.

After the turboshaft engine was assembled, Bang Hai began to build the test bench again.

After the test bench is built, it is time for the most critical commissioning link.

On the day of the test run, Sun Aiguo's psychology was actually stable.

Why is Sun Aiguo very stable? That's because the turboshaft engine manufacturing workshop is still manufacturing parts.

If the bangs are not sure, they will not let the workshop continue to manufacture parts at all.

Sun Aiguo and the deputy director in charge of the military industry were waiting for the test run.

The turboshaft engine was placed on the test bench, the various lines were properly connected, and the bangs were checked again.

Then the test run began, and with the start-up of the auxiliary power plant, the turboshaft engine also began to be officially started.

A low whine was followed by a loud whirring.

Turboshaft engines are also turbine engines in nature, with a loud aspiration sound masking the sound of jets.

Everyone listened to Liu Hai's orders, and Liu Hai didn't have much problem listening to the sound of the engine here.

Then keep a close eye on the gauge, ready to shut down at any moment.

After running at low power for more than ten minutes, the bangs went out.

Then carry out maintenance checks, mainly oil and other aspects.

There is also a maintenance inspection manual for maintenance inspections, which must be done in strict accordance with the maintenance manuals.

Everyone has no opinion on this, because those who have opinions have long been kicked away by Sun Aiguo.

There used to be some people in the factory who always thought they were justified, and then these people were kicked away and went to other units.

Of course, most of the companies that can be kicked out by motorcycle factories are not very good companies, that is, companies that don't need any technology.

No technical work is required, of course it takes effort!

After half a day of testing, Liu Hai looked at Sun Aiguo's expectant eyes and announced: "The first 1,400 horsepower turboshaft engine independently designed and manufactured by our factory was successfully tested!" ”

As for the specific power of this turboshaft engine, it has not yet been tested, and the bangs are estimated to be more than 1,400.

Sun Aiguo and the deputy director in charge of the military industry applauded one after another, and several people who participated in the test also began to applaud, although there were not many people present, but the applause was very loud.

The reason why there are not many people is because of the need for confidentiality.

"Will this engine be mass-produced in the next step?" Sun Aiguo asked very happily.

"Mass production has to wait a little longer, and the technology in the workshop has not yet been fully understood." Bangs shook his head.

"That's good!" Sun Aiguo understood what Liu Hai meant by the fact that the technology in the workshop could be mass-produced.

Of course, the technology that Liu Hai said is to understand the parts manufacturing technology, not the design technology.

"What's next for the whole machine?" Sun Aiguo hurriedly asked again.

"We still have to test the engine, and the design of the whole machine on my side will be completed in close to a month, and it is expected that the whole machine will be manufactured in mid-May, and if everything goes well, the test flight can be carried out at the end of July and early August." Bangs spoke.
