Chapter 479 Successful test run (second update)

In this era of semiconductors, there are many talented people, and when it comes to this, I have to mention Lin Daniu (Lan Ying.)

This is our country's semiconductor pioneer. Historically, in 1961, she presided over the research of an open-door silicon single crystal furnace.

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

In October of the same year, she produced my country's first gallium arsenide sample.

In 1964, she produced my country's first gallium arsenide diode.

In this world, our logs and mushroom technology are supported by bangs, especially the simulated missiles dropped in the early stage, as well as the centrifuge and high-temperature resistant materials later.

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

So at this time, our domestic electronically scanned phased array radar technology is seven or eight years earlier than in history.

Historically, due to strong winds, many studies have experienced faults, and people have been constantly replaced.

At this time, there is a lot less wind. In fact, when the wind is strong, it is often caused by lack of money.

This is like a family. If the family is poor, then the couple will have conflicts over some small expenses.

But if the family is wealthy, there will be much fewer conflicts in the family and much less wind, so a lot of research work can be continued continuously.

Don't underestimate the substitution of people in research work. This is a waste of time, because everyone who leads the research work has different ideas and directions, and there are some differences.

Historically, this was also the case when researching fighter jets. Substituting personnel midway resulted in the research progress being interrupted.

After Sun Aiguo reported to the leaders, the higher-level departments increased investment research in this area. The research equipment that should be provided was given to research equipment, and dealers were entrusted to purchase those that were not available in the country.

Among them, the semiconductor laboratory headed by Lin Daniu also received a lot of funds.

The 4004, 4001, 4002, and 4003 chips that Liu Hai bought as a gift are also being studied in various research institutes.

It can be said that the semiconductor technology of our era is not inferior to that of foreign countries.

In fact, Chinese people play a pivotal role in many high-tech projects abroad.

You must know that the chief designer of the Militia Log, one of the three largest logs in the world, Dongfeng, Minuteman, and Baiyang, is Lin Hua from Boeing. There is also the designer of the F14, also named Lu, and there is also the F35b active phased array. Radar is also said to be a female designer named Xu.

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

Of course, Liu Hai does not know the specific progress of these projects. Liu Hai also knows from some public information that our development in semiconductor technology is not bad.

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

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

Liu Hai From the launch frequency and load capacity of our launch vehicles, we can know that our development in this area is pretty good.

Sun Aiguo has been feeling a little uncomfortable recently, because since the superior department leaders learned about the motorcycle factory and began to design and manufacture helicopters by themselves.

No matter which department I go to report on something, these leaders have to ask about the progress every now and then.

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

As for superyachts, the main body design of the yacht has been completed and the keel laying has begun. What remains is the design of the interior decoration.

Liu Hai has to invest his energy here again, because decoration involves many departments and requires a lot of materials.

There are also ordinary yacht workshops that have also begun manufacturing.

In addition, Liu Hai also came up with a manufacturing process for instant noodles. The motorcycle factory has opened a workshop and is currently testing it. Liu Hai occasionally goes over to give guidance.

Not to mention super sports cars, super motorcycles and sports cars.

In addition, he was supervising two cartoons. Sun Aiguo felt that Liu Hai simply had more things to do than himself.

Because Sun Aiguo feels that his management is relatively simple and he just needs to delegate tasks to his subordinates.

The management of Liu Hai is more complicated because it involves technology.

Sun Aiguo couldn't ask Liu Hai's progress often. As for the overall progress, others didn't know.

Because now everyone only knows the parts drawings and manufacturing processes that Liu Hai took out.

As for the completion proportion of the overall parts, only Liu Hai knows when to start assembly and when to start testing, and the others don't know at all.

Liu Hai also needs to design the entire helicopter, so every time the leader asks, Sun Aiguo can only laugh.

Liu Hai had an idea in mind. The manufacturing of various parts of the turboshaft engine was going quite smoothly.

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

One of them is used for test run and life test.

The remaining bangs are ready to make two helicopters.

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

The first-time manufacturing contact with these parts inevitably leads to a higher scrap rate.

Ma Fuqiang began to feel that the scrap rate of parts in the factory was too high, and he might be called into a meeting by his leadership.

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

But here Ma Fuqiang discovered that there is no fear of parts manufacturing failure here. Every time there is a failure, he just needs to find out the cause of the failure and continue to manufacture it.

In Ma Fuqiang's group, whenever scrap parts are produced, everyone will gather together to look for problems and discuss them.

Everyone discussed a variety of things. At this time, Liu Gong would not point out any mistakes, but would let everyone make them again according to what they thought were wrong.

Obviously, the questions raised by most people are not the key point.

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

Ma Fuqiang didn't understand it at the beginning. Later, Ma Fuqiang discovered Liu Gong's approach, which gave everyone a better understanding of the manufacturing process and technology of parts.

Liu Hai has personally processed these parts, and of course he knows where problems are likely to occur. The reason why he doesn't talk about it first is to let everyone explore and discuss.

Liu Hai plans to train these people into the backbone. Although these people do not understand the overall technology, they only need to understand the component manufacturing process.

It was incredible, especially at this time, but Liu Hai was stunned by the wrong directions these people sometimes proposed, because according to Liu Hai's own understanding, it was impossible to think in this direction.

But this is the wrong direction, and many people still agree with it, so Liu Hai asked everyone to re-manufacture the parts according to their own understanding.

When everyone failed, Liu Hai stood up and pointed in the right direction, so that everyone could easily solve problems when manufacturing in the future, especially when manufacturing in batches.

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

Liu Hai used this production of sample helicopters to improve these people's understanding of the technical level.

I hope that next time I just show them the drawings, 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 preparing to cultivate a group of technical backbones for manufacturing aero-engines.

It is not necessary for these people to understand the design and principles of the entire engine, it is just enough for these people to be able to manufacture individual parts according to the drawings.

Of course, fortunately, these dozens of people were also led by people like Li Dali. The people in the maintenance department had experience in manufacturing helicopters earlier.

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

We were ready to start assembly, and the assembly of the turboshaft engine was also handed over to a specialized team.

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

Because Liu Hai cannot require these workers to be able to manufacture parts and assemble.

That was too demanding for others, so Liu Hai selected a few top technicians from these workers and began to lead them in assembling the finished products.

While others continue to manufacture parts, demand for turboshaft engines is high anyway.

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

There were not many people assembling the group, only three people.

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

Because it does not require too many people to assemble this kind of engine. If there are more people, it will be more complicated.

Moreover, making this kind of turboshaft engine does not require assembly line manufacturing. On the one hand, the demand is not that large, and on the other hand, it is not suitable for assembly line manufacturing.

"Today I lead everyone in assembling the first turboshaft engine designed and manufactured by our factory."

"You don't need to understand the operating principle of a turboshaft engine, you just need to know how to install each component correctly."

"For the first turboshaft engine, Li Dali and I will assemble it first. Ma Fuqiang, you take the assembly manual and compare the assembly steps of Li Dali and I. Zhang Jianguo, you are responsible for delivering the parts to us two. By the way, record it according to my requirements." Liu Hai started to assign tasks directly.

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

On the other side of Zhang Jianguo was the record responsibility card, and Li Dali and Liu Hai started assembling it.

Liu Hai picked up a part and began to talk about the part number and assembly method.

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

Ma Fuqiang was on the side comparing the outfit manual.

Liu Hai spent relatively little time actually doing anything, and he was basically instructing Li Dali on what to do.

Li Dali has been following Liu Hai for so many years, but he still has many shortcomings in professional knowledge of aero-engines, but his simple hands-on ability is not bad at all.

As for other people in the maintenance department, they also assume important responsibilities in several other groups.

Because parts are still being manufactured, having people from the maintenance department serve as the backbone allows other technicians to master the manufacturing technology as early as possible.

Ma Fuqiang learned for the first time that there are so many ways to assemble a turboshaft engine, and so many parts are assembled in it, most of which have strict assembly requirements.

Step by step, it took four days to complete the assembly of the turboshaft engine.

After the turboshaft engine was assembled, Liu Hai began to build a test bench.

After the test bench is built, the most critical test phase comes.

On the day of the test drive, Sun Aiguo's mentality was actually stable.

Why is Sun Aiguo so stable? That's because the turboshaft engine manufacturing shop is still manufacturing parts continuously.

If Liu Hai was not sure, the workshop would not be allowed to continue manufacturing parts at all.

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

The turboshaft engine was placed on the experimental bench, and all pipelines were properly connected. Liu Hai checked it again.

Then the test run began, and with the startup of the auxiliary power facility, the turboshaft engine also began to officially start.

A low whine was followed by a loud whirring sound.

A turboshaft engine is essentially a turbine engine, and the huge intake sound masks the sound of the jet.

Everyone listened to Liu Hai's orders. Liu Hai listened to the sound of the engine without much problem.

Then keep an eye on the instruments and be prepared to shut down at any time.

After running at low power for more than ten minutes, the bangs shut down.

Then perform maintenance inspections, mainly engine oil and other aspects.

There is also a maintenance inspection manual for maintenance inspections, which must be strictly followed.

No one had any objections to this, because anyone who had any objections had already been kicked away by Sun Aiguo.

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

Of course, most of those who can be kicked out by motorcycle manufacturers end up in not-so-good companies, that is to say, companies that don’t require much technology.

No technical work is required, but of course it does require 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 has been successfully tested!"

As for the specific power of this turboshaft engine, which has not yet been tested, Liu Hai estimates it to be more than 1,400.

Sun Aiguo and the deputy director in charge of 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, the applause was very loud.

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

"Can this engine be mass-produced next?" Sun Aiguo asked happily.

"We have to wait for mass production. The technology in the workshop has not yet been fully understood." Liu Hai shook his head.

"That's good!" Sun Aiguo understood clearly. What Liu Hai meant was that mass production would be possible if the technology in the workshop was thoroughly understood.

Of course, what Liu Hai refers to as a thorough understanding of technology is a thorough understanding of component manufacturing technology, not design technology.

"What about the manufacturing of the complete machine next?" Sun Aiguo asked quickly.

"We still have to test the engine, and it will take nearly a month to complete the design of the whole machine. It is expected to start manufacturing the whole machine in mid-May. If everything goes well, the test flight can be carried out by the end of July or early August." Liu Hai said. .
