Chapter 165: Cure the airplane's heart disease from the root [Request full order]

When he arrived at the test workshop, Wang Haoran became busy.

He first systematically explained to the technical staff brought by Dai Hongtao the technical structure of the fully automatic multifunctional single-cylinder washing machine he developed, directly drawing the structural diagram and important design and manufacturing difficulties.

Laboratory development of industrial products and large-scale production are actually two different things.

Because in the laboratory, you can design and create at any cost and create perfect works.

But the cost is very high.

But if you produce on a large scale and sell it on the market, you have to focus on cost control and production efficiency.

We strive to make the best product at the most appropriate cost.

As for Wang Haoran, he had actually already taken the issue of mass production into consideration when he was developing the product in the laboratory.

He is doing research based on the idea of ​​large-scale machine production.

Therefore, the fully automatic single-cylinder washing machine he developed is easier to implement.

There is basically no problem with raw materials.

And what about the key assembly line machinery and equipment?

Wang Haoran has also developed and modified it.

Wang Haoran spoke seriously for more than an hour and gave a general idea.

But the most important ones have basically been mentioned.

After he finished speaking, people in the test workshop applauded warmly.

Dai Hongtao held Wang Haoran's hand and said with emotion: "Comrade Haoran, you have solved all the problems for us."

Wang Haoran said: "It's mainly because I have a sense of urgency!"

"We are a backward country. We must speed up and catch up with the most advanced industrial level of the Lizard Country!"

"Next, let your people follow our technicians in the experimental workshop to familiarize themselves with the practical techniques."

"The people you brought here today are all considered the technology seeds for your future washing machine factory."

The technicians brought by Dai Hongtao began to operate the equipment in the laboratory to process various parts.

Of course, chips and electronic components are all supplied by Pangu Company, so they don’t have to worry about this.

Dai Hongtao and others stayed at Pangu Company until late at night that day.

They processed and assembled two washing machines in total.

After it was made, it was tested on the spot.

The washing machine that has just been produced works very well.

Everyone felt a sense of accomplishment.

By the time everyone finished work, it was almost 11 o'clock in the evening.

That night, Dai Hongtao's people were arranged to stay in the guesthouse of Pangu Company.

All the complete sets of drawings were also handed over to Dai Hongtao, asking them to take them back the next day.

Dai Hongtao was so excited that he couldn't sleep well that night.

Because his mind is full of grand plans and brilliant prospects.

Early the next morning, he woke up the people he brought with him one by one. He wanted to go back early because he had to start arranging the work.

We must hurry up and get approval for land to build the new factory.

The design drawings of the washing machine production line are all there, so we need to think about them and start processing and production as soon as possible.

Of course, Dai Hongtao had told Wang Haoran the night before that they would not say goodbye when they left.

On the bus back home, Dai Hongtao said to Li Gang: "Comrade Li Gang, we are going to build a new large factory."

"This factory will be very large, and is expected to cover at least 500 acres."

"After I go back, I will ask my leader to approve the land."

"I have an idea. I hope to build this new factory in your Licai Village, occupy your collective land, and pay you a large sum of rent every year, which is more than what you earn from farming."

"Then, after our factory is built, those in your village who want to work in the factory can do so. Those who don't want to work in the factory can start some business, such as building houses for rent, opening a small restaurant, a department store, etc. You will suddenly become city residents. Do you think this is okay?"

After hearing this, Li Gang frowned.

Farmers naturally have a complex about the land.

Farmers without land are like those without roots.

"We don't have much land in the first place. You have occupied 500 acres at once, so we don't have much left. I guess the food we grow won't be enough to eat," said Li Gang.

Dai Hongtao smiled and said, "Let's go back and discuss it. I think my proposal is definitely much more suitable than your farming."

"We will use 500 mu of your land and give you 500 yuan per mu per year. Just the land rent, you will have 25 yuan per year."

"You grow two crops a year now, so the gross income isn't much, right?"

At this time of year, crops are very cheap.

Wheat is only 1 cents per pound, and corn is 2 cents per pound.

An acre of land only earns 1 yuan if it produces 120 kilograms of wheat. What's more, nowadays, even a good wheat harvest can only produce to kilograms per acre.

The price given by Dai Hongtao is extremely suitable.

But Li Gang certainly cannot make the decision himself.

The land is collective, so we have to hold a collective meeting to discuss it.

After Li Gang returned to Licai Village, he hurried to find Li Jieshi.

After listening to this, Li Jieshi felt that this was quite worth doing. As long as more money was given to the members, there should be no problem, right?
So, a village meeting was held.

Before the meeting, Li Jieshi made a special phone call to Wang Haoran to consult him about this matter.

Wang Haoran smiled and said to Li Jieshi, "Uncle Jieshi, congratulations! Your village will soon become a small town."

"Let me do the math for you..."

Wang Haoran did the math for Li Jieshi, and at the end, he said to him, "If you agree to build this factory in our village, every family in Licai Village will have an additional income of at least 1 yuan per year!"

"Moreover, this income will increase year by year."

"This is really a great thing! Talk to the villagers about it. I believe they will strongly support it."

"By the way, when you sign the land lease contract with Benma Company, you also need to sign a clause that the rent will increase year by year, about 5% per year."

After talking to Wang Haoran on the phone, Li Jieshi convened a general members meeting that evening.

In the 80s, general meetings of all members were still held several times a year, and any major events in the village had to be discussed collectively.

That evening, a general meeting of members was held.

At the beginning of the meeting, when Li Jieshi announced his plan to introduce Benma Company to build a factory in the brigade and that 500 acres of land in the brigade would be allocated to the company to build a washing machine factory, there was an uproar at the scene.

The masses were unanimous in their opposition.

Many people feel that if farmers lose their land, they will have no support and no way out.

So, this cannot be done.

Li Jieshi almost couldn't keep his composure.

Until he shouted: "Comrades, before the meeting, I spoke with Comrade Wang Haoran, and he strongly supports this matter! He believes that this will be of great benefit to each of us!"

The scene gradually quieted down.

Because, Wang Haoran is now like a god in the eyes of every villager in Licai Village.

This young man has done so many good things for Li Cai Village.

Without him, there would be no good life in Licai Village today.

Since he said this is a good thing, let's listen to Li Jieshi's explanation.

Li Jieshi began to imitate Wang Haoran and calculate the accounts for the villagers, including the current interests and the long-term development.

Farming can only make a living, but industry can make you rich.

Workers in the city don't have land, but they obviously live better than farmers! Therefore, losing land is not a big deal, as long as it increases the chances of working in factories and doing business at home, it is a good thing.

You should always take a broad view of the scenery. If your vision is limited to an acre and a half of land, you will always be destined to poverty and suffering!
A Benma Company can turn Mafang Town into a strong industrial town. If we build a large-scale factory in Licai Village, it will be no problem for every household in the village to become an annual income of ten thousand yuan.

Li Jieshi persuaded the villagers earnestly and finally reached a consensus: to give up 500 acres of land to allow Benma Company to build a factory in Licai Village!
While Wang Haoran was taking time out of his busy schedule to develop a fully automatic single-cylinder washing machine, the search for rhenium metal was also in full swing across the country.

Because Wang Haoran had previously made some conclusions, such as rhenium metals are mostly associated minerals, and they are easily associated with molybdenum ores, copper ores, etc. Among them, the probability of being associated with molybdenum ores is the highest.

So this greatly narrows the scope of the search.

Since rhenium likes to be associated with molybdenum, we should do more work on molybdenum mines!

On September 9, a team of scientists from Qin Province discovered associated rhenium metal in the molybdenum mining area of ​​Huanglongpu in the province.

Moreover, they also obtained extremely high-purity rhenium through refining methods. This news quickly reached Wang Haoran's ears.

Wang Haoran naturally set off immediately and came to Qin Province again.

Then, accompanied by Xi'an Aircraft Industry Corporation's chief engineer Ge Xiaobing and others, he took a car to Huanglongpu.

There, he saw the rhenium metal powder refined by scientists from Qin Province, which was of extremely high purity and quality.

Wang Haoran listened to the scientists’ estimation of the reserves of rhenium metal associated with the Huanglongpu molybdenum mine: the mine contains at least a hundred tons of rhenium.

Ge Xiaobing sighed and said: "The reserves are too small, and the difficulty of refining is quite large. I am afraid that new large-scale refining equipment will be needed."

Wang Haoran smiled and said, "A reserve of over a hundred tons is already quite a lot."

"Rhenium metal is a scarce metal on Earth."

"No matter how difficult it is, we must extract rhenium at all costs."

"Without this thing, there is no way to manufacture high-quality aircraft engines, and the development of the aviation industry will be greatly affected."

"Next, we have two things to do!"

"The first thing: develop an efficient and low-cost method to extract rhenium from molybdenum ore."

"The second thing is that we need to research the manufacturing method of rhenium single crystal blades!"

Both tasks were directed by Wang Haoran.

Wang Haoran has ready-made technical means in his mind.

He only needs to point out the direction and route of the research when working with the team to greatly speed up the progress of the research.

In fact, the most important thing in scientific research is to find the right method and route. As long as the direction planning is completely correct, the speed of producing results will be very fast.

In just four or five days, the laboratory's method of quickly extracting rhenium was broken through.

A month later, the improvement and upgrading of molybdenum ore processing and refining equipment was basically completed.

This set of equipment can easily decompose and refine rhenium metal while processing and refining molybdenum metal.

Of course, the focus of future mining and refining of the Huanglongpu molybdenum mine will no longer be molybdenum, but rhenium!
As for metallic molybdenum, it is just being refined as a side job now.

While improving and upgrading the refining equipment, Wang Haoran is also researching equipment for processing rhenium alloy blades.

Some people may ask: Why do aircraft engine turbine blades have to use single crystal blades?
This is because the working environment of these blades is very harsh. Not only are they exposed to a high temperature of one or two thousand degrees, but each blade is also subjected to a very large force, which is roughly equivalent to the horsepower of a 2.0-liter off-road vehicle.

The 1000 single-crystal blades in a 60-kg engine are absolutely key components.

Not only do they withstand high temperatures and enormous forces, but when the blades rotate at high speed, the tangential speed can reach 450 meters per second, which ordinary metal blades simply cannot withstand.

The metal rhenium is resistant to high temperature, oxidation and thermal corrosion, and has good fatigue resistance and fracture toughness.

In fact, the amount of rhenium in rhenium single crystal blades is quite small, only about two to six percent.

The main reason is that this thing is too scarce and we can’t afford to use it in large quantities.

Producing rhenium single crystal blades is not an easy task.

It requires very sophisticated equipment, mainly heat treatment furnaces and single crystal furnaces with a temperature difference of plus or minus three degrees.

However, Pangu currently has the heat treatment furnace and single crystal furnace it needs.

Moreover, these two devices are also important equipment needed by the electronics industry.

Wang Haoran only needs to make slight modifications to it before he can use it.

As a result, by late October 1980, the processing and refining of rhenium metal in Huanglongpu had become regular.

At the same time, Wang Haoran also set up the production workshop for rhenium single crystal blades at Xi'an Aircraft Industry Corporation.

All kinds of equipment are already in place.

When testing the heat treatment furnace and single crystal furnace, Ge Xiaobing was shocked.

In fact, the domestic aviation industry in Longguo has been carrying out research and development of single-crystal blades.

After all, single crystal blades perform much better than ordinary turbine blades.

However, research on single crystal blades has not been so smooth.

It's mainly stuck on the equipment.

Also, the first generation of single crystal blades actually do not contain rhenium, but are just ordinary alloy metals.

Using rhenium metal to produce single crystal blades is an important research direction of Jusa's aviation industry today.

In fact, they have not yet successfully produced single crystal blades of rhenium alloy.

"Comrade Haoran, I never thought that our domestic companies have already made heat treatment furnaces and single crystal furnaces so well."

"We have always wanted to find opportunities to import these two types of equipment from abroad!"

Ge Xiaobing said to Wang Haoran.

Wang Haoran smiled and said, "It seems that we should regularly conduct a national industrial census to have a clear understanding of our own assets, haha!"

Ge Xiaobing hesitated for a moment, but still asked again: "Comrade Haoran, what is the progress of the aircraft engine development work you are responsible for?"

Wang Haoran said: "It's almost done."

"I have already established a relevant scientific research team in Beijing, and my partners are all well-known experts from Beihang University and the Institute of Aeronautics."

"Now, the only thing left in the development of the entire engine is the rhenium single crystal blades and the rhenium alloy single crystal engine nozzle."

"We are almost the most important and final link."

Ge Xiaobing was very excited after hearing this.

Because the engine is one of the most important parts of an aircraft.

Once the engine was done, the hardest part was solved.

As for the avionics system, that is Wang Haoran's strong point, and Ge Xiaobing wouldn't even ask about it.

"Great! Then when do we start making rhenium single crystal alloy?" Ge Xiaobing said with a smile.

Ge Xiaobing originally didn't quite believe that Wang Haoran could produce the J-10 and equip the troops within two years.

But now, he found that the progress was unusually fast.

The research on the aircraft body at Northwestern Polytechnical University has almost been completed. The leader, Professor Xie Liangwu, has even built a model and blown it through a wind tunnel.

As a result, the model performed very well in the wind tunnel.

This is almost like doing it in one go.

Ge Xiaobing has a good relationship with Xie Liangwu. He heard from Xie Liangwu that the reason why the J-10 fuselage was designed so smoothly was mainly because Wang Haoran had already determined the shape and aerodynamic layout of the aircraft...

Ge Xiaobing never thought that a big shot like Xie Liangwu was actually just assisting Wang Haoran.

Wang Haoran smiled and said, "All the materials are almost ready. Let's get started tomorrow!"

The next morning, Wang Haoran, along with several assistants from Beijing Institute of Technology, began to personally try to develop rhenium alloy single crystals.

Of course, many technical personnel from Northwestern Polytechnical University and Xi'an Aircraft Industry Corporation also participated.

The equipment is very powerful and easy to use, so the development was quite smooth.

In the afternoon of that day, the first group of 60 rhenium alloy single crystal blades were manufactured in the equipment.

Wang Haoran immediately led people to conduct comprehensive tests on it in terms of high temperature resistance, corrosion resistance, etc.

The test results show that the various parameters of this rhenium alloy single crystal blade far exceed those of the turbine blades of aircraft engines imported from abroad!

The test results are quite encouraging.

After Wang Haoran announced the test results, there was warm applause and cheers at the scene.

The successful development of aircraft engine turbine blades indicates that domestically produced high-efficiency turbofan engines are about to be launched!
For many years, China's aircraft engine development has been a weak point.

Because of the poor quality of the engine, the overall performance of our fighter jets is not high, and our air force is suppressed by our opponents.

Now, this situation is about to change!

"Comrade Haoran, when can the manufacturing of the entire aircraft engine begin?" Ge Xiaobing asked Wang Haoran during dinner that night.

Wang Haoran smiled and said, "Soon."

"Once your equipment is upgraded, I think we can start trial production of our engines."

The successful development of rhenium alloy single crystal blades should have been a major event, but due to the principle of confidentiality, this matter was not publicized to the outside world at all.

It was already early November when Wang Haoran returned to the capital.

Xiao Lijuan's due date is in December.

Wang Haoran felt very guilty towards his wife: she was so pregnant, and she still had to cope with studying and taking care of Wang Xinghai...

And I hardly even have the time to spend with her.

Wang Haoran decided that he absolutely could not go out in December and that he should make more time to fulfill his responsibilities as a husband.
