The passionate years starting from the college entrance examination

Chapter 261, in full swing

Mid-to-late November 1962, Beijing.

In the suburbs, in the technical training room prepared for Middle Eastern tycoons like Barzani, learning was in full swing.

In the conference room next door, Barzani, Bouteflika, Jibril, and McCalim were discussing matters with solemn faces.

Things on Hong Kong Island have been passed on to them.

Now they must face a question: Should they continue to stay in the capital?

I've paid for the lithography machine, but I haven't seen the goods yet.

I have just started to learn technology now, and I haven’t even scratched the surface yet.

All four of them felt very unlucky. Why did something like this happen just after they signed the contract?

If they want to bring the lithography machine back to their country next year, they may have to go overland.

However, it is so far away by land!

The most critical thing is that they currently do not have cars suitable for transporting lithography machines.

After discussing for a long time, Barzani and the others still did not come up with any results.

Alexander Shokin, who was named, was excited and quickly responded:

Brezhnev in the office was very happy at this time!

Because two aircraft carrier fleets came from Hong Kong Island, there was no doubt that China Resources' lifeline was cut off in an instant.

I raised my head and took a sip of mellow vodka. It was particularly comfortable in this cold winter.

When Brezhnev heard this, he immediately asked curiously, what is the cost?

The price of Sony's TR610 has been reduced to thirty US dollars. Only in this way can it achieve a slight sales volume.

"Our production cost is currently US$40 per unit." Alexander Xiaokin responded respectfully.

Without the money bag of China Resources, Beijing will definitely suffer.

The profits from this part of the market have been plundered by China Resources.

No one knows how much market potential is left.

Therefore, China Resources' total revenue just reached 3.6 billion US dollars.

Brezhnev felt a twinge in his heart when he thought of the report that China Resources' revenue this year was as high as 3.6 billion U.S. dollars!

In fact, the revenue was originally only 3.47 billion U.S. dollars, but before the arrival of the aircraft carrier, North American second-tier dealers like Raymond and Srikvasant contributed more than 100 million U.S. dollars in revenue.

But the TR610 radio has been on the market for several years and is already an outdated product. Not to mention that the cost has been recovered early, people don’t know how much money they have made.

As we all know, the calculator copied in Moscow was the first to be eliminated.

This is equivalent to one-sixtieth of Moscow's annual gross national product.

Priced at US$59, Hua Hin Radio has never failed or lowered its price since it was launched in April.

Horror!

So Brezhnev was naturally very unhappy about such a thing.

Originally, Brezhnev thought that IBM in North America could last longer.

Now that Moscow has produced a radio, will it definitely be able to make calls?

Not only is the design and product quality inferior to the Huayue calculator, but the same is true for the cost.

What's more, if the radios produced in Moscow are not competitive in terms of signal and headphone quality, they will certainly not pose a threat to Huaxin Radio's market dominance.

But Brezhnev had little interest in such beauty.

Once they break the contract, according to the contract, they will lose at least one to two hundred million.

Unexpectedly, he lost just as quickly.

"Alexander, now that China Resources can no longer ship goods, do you have any ideas?"

"I think we can compete with Hua Hin Radio"

Brezhnev did not understand technology and was not very clear about sales and marketing.

"Comrade Secretary, we have redesigned our calculators and radios."

Not compared to low-end radios, but high-end radios like Huaxin Radio. Haha, let’s go to the market and try it.

Last year, in 1961, Moscow's GDP was only US$216.562 billion.

So, how does Moscow compare with others?

They cannot afford such losses.

Even for professionals, it is difficult to estimate.

Brezhnev was certainly very happy when he thought of this scene.

Since transportation and other costs haven’t been calculated yet, wouldn’t the cost of a radio by then be more than forty-five dollars?

You know, the global market for radios now exceeds two million units.

How to do?

What a dilemma!

Moscow, Kremlin.

But if they just treat it as if they haven't seen what happened on Hong Kong Island, then it will undoubtedly be very difficult for them to transport lithography machines by sea in the future.

However, China Resources Corporation, a company, directly handed over 3.6 billion US dollars in revenue, which is not too eye-catching.

Looking at Alexander Shokin in front of him, Brezhnev was in a good mood and not angry.

Outside the window, the city of Moscow has long been covered in silver, and it is breathtakingly beautiful.

But this answer did not satisfy Brezhnev.

Just because the radio is a high-tech product, he is a bad old man, so naturally he is not very familiar with these things.

Seeing that Alexander Shokin was so confident, Brezhnev had no choice but to let him go!

"By the way, I asked Pandelela Semiconductor Company to spend 400 million US dollars to purchase 20 photolithography machines. Please give me a prompt and create some trouble for them."

Regarding this matter, Brezhnev naturally had no intention of letting China Resources go.

Because he is not sure what the trend is in North America and when the ban will be lifted.

But no matter what, their plan in Moscow still needs to be implemented.

After all, if this US$400 million is thrown out as bait, it is bound to play its due role.

Alexander Shokin responded quickly, with a very serious expression on his face, but the corners of his mouth were slightly raised, indicating that he was in a good mood.

While Moscow was already taking action, the city of Armonk, New York State, North America.

IBM corporate headquarters, president's office.

Little Watson's health gradually improved a lot, and he was finally able to work a little better.

Especially some time ago, Srikvasant, the president of Walls Semiconductor Company, brought back a lot of goods from China Resources Company from Hong Kong Island.

Therefore, IBM's revenue can increase to some extent.

In addition, there is something happening on Hong Kong Island, and if China Resources wants to ship goods, it will be extremely difficult to do so.

Since China Resources' goods cannot be shipped, the next time is for their IBM company to perform.

So Watson is very happy and is not worried about China Resources' products suddenly coming out.

Walls Semiconductor is actually a subsidiary of IBM.

It's just that the outside world doesn't know it yet.

If Watson hadn't woken up too late, otherwise, he should have done this in the first place.

"Chinese is really broad and profound. I build plank roads openly and secretly travel through Chencang. Haha, I can do it in the future."

After reading Sun Tzu's Art of War, little Watson was extremely happy.

He still remembers what his Chinese teacher said, which is to know yourself and your enemy and you will never be defeated in a hundred battles.

Although it is difficult to know everything about the enemy China Resources Company.

But isn’t little Watson working hard?

"BOSS, Winkelmann and McDowell are back."

In the office, after hearing the secretary's words, Watson quickly asked the other party to call them in.

At the same time, he stood up to greet him.

But as soon as he stood up, Winkelmann and McDowell were already at the door of the office.

"Watson, we are back. You don't know what we found when we went out this time. Haha, you might not believe it."

“We finally know why the signal of China Resources’ Huaxin radio product is so good over there.”

"It definitely uses new technology. This technology is definitely very important to us, and Bell Labs is also very interested in it."

At this moment, Winkelmann no longer has a Mediterranean hairstyle, but a bald head.

Because in the past year or so, in order to catch up with China Resources, he often stayed in the laboratory.

This caused his hair to fall out faster.

Even so, Winkelmann was still very excited at this moment, and reported the situation to little Watson with great joy:

"Also, the old guys at Princeton University also said that they will also contact Argonne National Laboratory for help."

"They are also very interested in this emerging signaling technology."

"Watson, you know, within three months, we will be able to come up with this technology."

hiss!

I heard that Bell Labs, Argonne National Laboratory and other units mentioned by Winkelman were actually so interested in such technology.

Little Watson couldn't help but take a breath of cold air.

Good guy!

What a good guy!

The existence of these two laboratories is of course very familiar to the native Watson.

Because Watson joined IBM early, he started as a salesperson at the bottom and worked his way up to his current position step by step.

He is very clear about not only the thoughts of the lower-level employees, but also the vision, structure, and knowledge of the senior management.

IBM's ability to become a leader in the computer industry over the past decade or so was the result of Watson's personal creation.

So he knows the power of technology research and development, and naturally knows scientific research institutions such as Bell Labs.

Bell Labs, Argonne National Laboratory, etc. are all very powerful entities in North America.

Now, these scientific research institutions have joined forces with Princeton University to launch an attack on the new signaling technology mentioned by Winkelman.

Then it won't take long, and this technology will definitely be conquered.

Thinking of this, Watson was certainly very excited.

It was also understandable that Winkelmann and McDowell were laughing with excitement.

This is indeed good news.

"Okay, okay, thank you for your hard work."

Little Watson praised and cared about Winkelman and then turned the topic to the quality of the headphones.

On this point, McDowell has already addressed the issue.

To put it simply, it’s a matter of materials. It’s still not possible to determine the quality of headphones developed using new materials, but we can look forward to it.

Hearing this, little Watson became even happier.

"What about the cost?"

"It's not certain yet. We can't make an estimate until everything comes out."

When Little Watson heard this, he nodded slightly regretfully.

Although I understand, I am still somewhat worried.

What if the cost is too high?

After all, this time we are cooperating with scientific research institutions such as Bell Labs and Argonne National Laboratory. These institutions are notoriously gold-eating beasts.

Although IBM has money, it cannot withstand the terrifying speed of the gold-eating beast.

What's more, IBM is a listed company and is very strict about financial reporting or cost control.

However, it was useless for him to worry and could only wait for the results.

Just as IBM was in full swing, Cray, Texas Instruments and other companies also took action.

Everyone is racing against time.

In the coming time, after China Resources' inventory products are sold out, the market will be vacated.

At this time, even if Cray, Texas Instruments, and IBM feed consumers shit, they will have to pay for it.

In such a big market, people will naturally not come up with defective products. Otherwise, there will be no competitiveness at all.

After all, competition for products such as radios and calculators is fierce.

So everyone became the Eight Immortals crossing the sea to show their magical powers and prepare for the next war.

London, Sturwalk, executive meeting.

The president of Pandaria didn't know what happened on Hong Kong Island until very late.

What a great guy!

Great Britain's aircraft carrier fleet actually ran to Hong Kong Island without saying a word. That was a colony of Great Britain. Why did it go with the aircraft carrier?

What if the gun accidentally goes off?

Do you think the red beards deployed at Dinga Airport and Okajima Airport were not exciting enough before, but now the aircraft carrier fleet is arranged, which is exciting enough?

Or is it that MacMillan likes to play with heartbeats?

Fake!

Because of this incident, the peaceful scene where Stewalk Company was just making money was completely gone.

Despicable and shameless politicians!

Pandaria and other senior executives really hate those bastards in Downing Street. They are all pretending to be stupid. Look what kind of decision they made?

Business, or capital, hopes to operate in a relatively peaceful situation.

Especially for gentlemen like Pandaria, who are relatively conservative and like to be decent, but are short of money, making money while lying down is the happiest thing.

As a result, it is now ruined by those bastards in Downing Street.

Of course, let's get rid of the criticism, now we still need to think about countermeasures and how to deal with the next thing.

Pandaria and the others hate the word "change".

Because the change means their workload has skyrocketed, which means they need to work overtime.

They prefer partying to working.

How funny!

Stewalk Company was busy holding meetings to discuss response plans.

On the opposite side, the Federal West Germany, Siemens, has already come up with new products.

Eichendorf, the technical director of Siemens, danced and said at the executive meeting:

"Everyone, we have copied the latest radio. The signal is not much worse than the Hua Hin radio, and the quality of the headphones is the same."

"In addition, we have also improved the calculator, and now the cost has dropped to one hundred dollars. With such a huge cost advantage, even if we price it at one hundred and fifty dollars, we are still very competitive."

After hearing Eichendorf's words, President Felix and others were very excited.

The market vacated by China Resources will definitely belong to their Siemens company!

Their Siemens company will carve up this part of the market.

"Okay, then we will seize the time to arrange factory production now. This time we will win back the market no matter what."

Felix said solemnly, and other executives nodded hurriedly.

Because they all need to be responsible for the control of relevant processes, once the entire Siemens company is running at high speed, the efficiency is still very high.

Enterprises such as Italian Microelectronics and Thomson Corporation have also made strategic adjustments.

Especially Sony, Fuji and Toshiba here in Tokyo are even more crazy.

In short, because of the emergence of two major aircraft carrier fleets in Victoria Harbor, giants in the global electronics industry have seen hope.

If China Resources is a pioneering cow, then companies like them are just calves that follow behind to pick up bargains.

Beijing, Cuihua Hutong.

Hu Pinggu, who had just finished storing Chinese cabbage for the winter, smelled the fragrant aroma of food when she returned home.

There is delicious food again at home.

Several half-year-olds, including Chen Yuanchao and Chen Wei's two brothers and sisters, are all here in the living room, and they can't wait.

Lao Chen's family still follows rules when it comes to eating. Children won't move their chopsticks when there are no people around.

Of course, everyone will not strictly abide by this rule all the time, and sometimes they will be flexible.

Chen Si is now over a year old, so she still needs to talk to her about these rules.

The education of children must start from an early age.

"Have a meal!"

Seeing Hu Pinggu sit down after washing her hands, Chen Gonglu spoke.

As a result, several little kids couldn't wait to use their chopsticks.

"Slow down, no one will compete with you for food."

In front of the hot dinner table, adults like Chen Guohua and the others laughed and talked to the little kids like Chen Xiaomin.

Chen Wei, who had just learned to use chopsticks, tried to pick up a piece of meat very clumsily, but it was too slippery and he couldn't pick it up for a while.

He doesn't let his mother do it for him, nor does he let his grandparents do it for him, he has to do it himself.

Everyone looked at it with a smile and found it very interesting.

Until Chen Yuanchao couldn't stand it anymore and helped him pick it up, he immediately flattened his mouth and cried. Then he was scolded by his father.

For a time, the atmosphere in the living room became more lively.

Today is Xiaoxue, which is not a big holiday, but the Chen family is happy today.

Chen Lihua was pregnant for more than two months now, and it was Yu Moli who took her pulse.

Because Chen Lihua remembered today that she seemed to have not been to her aunt for a while, so she took advantage of today's holiday and ran back to ask Yu Moli to help take her pulse.

Yu Moli, who has studied traditional Chinese medicine with Professor Ji Wenmei for several years, has seen a sharp increase in his pulse-taking skills.

So she could quickly conclude that the seventh sister was pregnant.

This is a great thing.

Because of this, the dinner at home today was much richer than usual.

"Tomorrow you and your brother-in-law will go to the hospital to confirm. I also want to see if the abortion prescription they prescribe at the General Hospital is different from mine."

Hearing Yu Moli's words, Gui Zhiting wanted to shake his head, but Chen Lihua just smiled and said:

"That's not necessary. I trust your medical skills, sister-in-law."

Chen Guohua said from the side:

"Seventh Sister, her intention is very clear, she just wants to compete with the doctors from the General Hospital."

Snapped!

Yu Moli suddenly slapped Chen Guohua angrily, but the whole family burst into laughter.

Suddenly, under Yu Moli's persuasion, Chen Lihua went to the hospital.

In fact, there is no need to go, and I know there is no difference.

Because Yu Moli had given birth to two children, the birth control prescriptions she drank before were all prescribed by Ji Wenmei.

Ji Wenmei's family is a family of traditional Chinese medicine inherited from the imperial doctors of the previous dynasty. She is a professor at the Beijing University of Traditional Chinese Medicine, and she is very powerful.

If she hadn't declined the job interview with the Health Bureau, she might still be a part-time doctor at the Health Bureau.

Therefore, after Chen Lihua saw the doctor, her pregnancy was confirmed, and she brought back the prescription for miscarriage.

After Yu Moli looked at it, he smiled and nodded. It was indeed the same as what she said.

Traditional Chinese medicine focuses on regulating the body.

Everyone's body is different, so the prescription that is suitable for Mo Li's miscarriage may not be suitable for Chen Lihua.

Of course, these are all very similar.

Because the current living conditions are quite different, Yu Moli is in relatively good health because she and her eldest brother have been two siblings since they were young.

But Chen Lihua is different. She has several brothers and sisters, so her nutrition since childhood was not much better than Yu Moli's.

Naturally, the two of them had different pregnancies.

Time flies like water, and it’s already December in a blink of an eye.

The capital was covered in snow overnight because heavy snow had arrived.

The temperature was extremely low, about 20 degrees below zero.

After Chen Guohua sent Yu Moli to Peking University, he went directly back to Zhenhua Research Institute.

After arriving at the unit, we went directly to the aerospace engine laboratory.

"Director Xie, let's hurry up and try to complete the finishing work of the gyroscope today."

As soon as he walked into the laboratory, he saw Xie Dingyi and Chen Guohua said immediately.

As we all know, gyroscopes are a very important part in the aircraft field and are a key core technology.

Gyroscopes made based on the principles of gyro mechanics have a wide range of applications, such as aviation, aerospace, navigation, weapons, automobiles, biomedicine, environmental monitoring and other fields.

The gyroscope proposed by Chen Guohua is completely different from previous gyroscope technology.

Large UAVs are inherently a very innovative field of aircraft, and gyroscopes naturally require higher requirements.

Its advantages include small size, light weight, low cost, high reliability, low power consumption, large range, and easy digitization and intelligence.

In addition, it still has the advantage of very high accuracy in dealing with harsh environments such as large temperature changes and large vibration and impact.

Before designing the large drone, Chen Guohua had already determined one thing, because it can fly to a height of 10,000 meters.

It is a high-tech technology prepared for the troops, so naturally it is not just about flying at a high altitude.

Even, in the future, drones will develop towards stealth.

It not only requires higher-tech invisible coatings, but also requires solving its engine sound problem.

The sound of the engine is so loud that it insults the word stealth.

"Okay, I also hope that the gyroscope problem can be solved today, but it has really been bothering us for a long time."

Upon hearing this, Xie Ding immediately responded with a smile.

There were several researchers beside them, and they looked even more happy, and hurriedly followed Chen Guohua and the others to the test bed.

"It won't take long. Haha, let's work hard today and see if we can figure it out."

Chen Guohua smiled slightly and then started working.

The drone is equipped with a three-way gyro gimbal, which can provide anti-shake protection in six directions.

However, after Chen Guohua and the others were busy for a while, Xue Jinquan came over with a camera.

I'm also asking about gyroscope issues.

Or to be more precise, it’s about optical image stabilization.

The lens equipped with the drone has very high requirements on the camera.

Especially this large drone can fly to an altitude of 10,000 meters, which is a very high altitude for many aircraft.

In this ceiling-limiting process, the technical requirements for cameras are naturally very high.

As we all know, the principle of optical image stabilization is to detect the slight movement of the camera through the gyroscope in the lens, transmit the signal to the microprocessor, and calculate the amount of displacement that needs to be compensated.

Then, through the compensation lens group, the lens is compensated according to the direction and displacement of the lens, thereby effectively overcoming the image blur caused by the vibration of the camera.

"This question is very simple. You also know that we not only provide optical image stabilization technology for the camera lens, but also electronic image stabilization."

After listening to Xue Jinquan's question, Chen Guohua directly gave the other party a reassurance.

Electronic anti-shake technology is directly integrated into hardware and software. Although this will increase the load on the microprocessor, it is definitely better to have an extra layer of protection.

Moreover, for microprocessors, Chen Guohua has designed a chip that integrates more transistors. The heat dissipation, power consumption, performance, etc. are all about 50% higher than the previous generation chip.

If large drones don't have too high requirements for photos, in fact, only electronic anti-shake technology is needed.

After all, as we all know, optical image stabilization is not something you can do if you have money. It requires strong technical support and many difficulties need to be overcome. The most important thing is that this thing will increase the weight of the drone.

Just like a small drone, Chen Guohua directly canceled the optical image stabilization technology.

After a while, before Chen Guohua finished speaking, Xue Jinquan already understood.

Seeing this, Chen Guohua smiled and stopped talking.

Xue Jinquan is very smart and can solve many things easily. Chen Guohua likes this most about him.

If the researchers in Zhenhua Research Institute were all super academic researchers like Xue Jinquan and others, then Chen Guohua would be much more relaxed.

For the same technology, Chen Guohua only needs to briefly chat with Xue Jinquan and others, and they will understand it.

But for ordinary academics like Wan Qingxuan, they would have to spend twice as much time or more energy.

This is the difference.

After the working hours of the day were over, the finishing work on the gyroscope was still not completed.

However, on the second day, it was completed in the middle of the afternoon.

Finally conquering the gyro gimbal, the next step is the remote control system.

This system includes a transmitter, receiver, and remote control station, which are mainly used to control the flight direction and height of the drone. They are the two most important devices for controlling the drone.

Ten thousand meters is ten kilometers. The drone needs to fly to this distance, so the signal optimization must be done to the extreme.

Previously, the spy pigeons designed and developed by Chen Guohua and his colleagues could transmit signals as far as nine kilometers.

In other words, using such technology is naturally not possible.

You know, when a large drone flies to a high altitude, it cannot just stay above the ground where the remote control is located.

The drone definitely needs to be moved, once it reaches an altitude of 10,000 meters, it can fly to other places.

"Come on, is everyone here?"

In the laboratory, Chen Guohua clapped his hands and explained the remote control signal technical issues to everyone.

The remote control signal technology of large drones uses wireless microwave video transmitters in GHz.

"Did you see the four hexagonal screws on the drawing? What is the function of this three-layer design?"

It was said that he was giving a technical explanation, but out of professional habits, Chen Guohua immediately switched to class mode.

"Director Chen, I know!"

Shi Jiayi raised her hand and was very proactive. Chen Guohua nodded to indicate to the other party.

"This is a heat dissipation method. We all know that the same electronic components have different failure rates after working in environments of 30 degrees Celsius and 50 degrees Celsius for half a year."

“So our previous approach was to add heat sinks or thermal conductive materials to the components on the circuit board that generate a lot of heat, and then remove the heat through fans or water cooling.”

"However, if this is done, the temperature of the product's casing will also be higher. In this case, adding a fan and the metal casing will dissipate heat quickly. In this case, it is not impossible."

"However, since we are designing a drone, we need to consider one thing: reducing the weight of the drone itself, so we have this ingenious three-layer design."

After hearing Shi Jiayi's answer, Chen Guohua smiled and asked the others, was the former right?

Technical explanations are provided in a class-like manner to make everyone more familiar with the entire technology and improve research and development efficiency.

Then, Chen Guohua smiled and continued to ask:

“Then what’s so clever about the design of this cavity?”

This time it was Shao Fuchi who answered the question.

There are three main points. The first is that the circuit board conducts the heat of the circuit board to the inner cavity through a large-area thermally conductive silicone pad.

The second is the many heat dissipation strips on the cavity to increase the contact between the cavity and the air. The third is the design of air ducts to speed up the air circulation through fans to take away the heat from the cavity surface.

After briefly talking about these design-level technologies, Chen Guohua began to switch to real technical explanations.

From cavity structural parts to circuit board technology, to connectors, special sealants and other technologies.

It can be said that Chen Guohua has taught everyone the entire wireless microwave video transmitter technology, inside and out.

Even on level conversion chips, receiving front-end chips, frequency conversion chips, etc., Chen Guohua explained them very carefully and thoroughly.

While Chen Guohua was teaching researchers, Peng Shilu, Zhao Renkai, Huang Xuhua and others had already gathered together for a meeting at the 909 base.

"After our calculations over this period of time, we can basically confirm that this nuclear submarine design drawing is a very perfect nuclear submarine design drawing with completely accurate data."

Peng Shilu looked at everyone very seriously and said.

There was emotion and trembling in his tone.

As we all know, the nuclear-powered submarine project was launched in 1958.

The nuclear submarine project was only launched at the beginning of this year, but the original space-time was not officially launched until 1965.

"This nuclear submarine design uses 47,000 parts and requires more than 1,300 kinds of materials. According to the list in the appendix, it can be seen that 1,080 kinds of materials have been developed so far. ."

Listening to Peng Shilu's words, Zhao Renkai, Huang Xuhua and others were filled with emotion.

This nuclear submarine material from Beijing is simply awesome.

It took them half a month to recalculate the design drawings. They don't know how much time it took to design the drawings in the capital?

What puzzles them the most is that there are obviously no other nuclear submarine projects in Beijing, let alone nuclear submarine-related scientific researchers.

After all, all researchers related to nuclear submarines across the country have been transferred to Base 909.

So where did this design drawing come from?

The team led by Huang Xuhua is responsible for the hull of nuclear submarines, and they have a deeper impression of this design drawing.

From the beginning of this year, Huang Xuhua and the others took calculators and slide rules and began to calculate thousands of data, solving the problems of hull design one by one.

However, almost a year later, they are still not finished.

As a result, the capital city brought out a blueprint. When they saw the blueprint, Huang Xuhua and the others burst into tears.

But after the calculation was over, he was filled with complexity and a little resentment.

Why?

The drawings they had worked so hard to design, such as the one from the capital, were vastly different.

Nearly a year has been wasted now. Why not take it out earlier?

Of course, this bit of resentment is insignificant in the face of the huge surprise.

Halfway through the meeting, the above reply arrived.

The capital city approved their application, so Peng Shilu, Zhao Renkai and Huang Xuhua discussed it and decided that the three of them would take several researchers to the capital city to talk to the designer of the drawing.

The group of them did not delay, arranged all the affairs of the 909 base, and set off for the capital.

When the train they took arrived in the capital, the clear sky seemed to indicate something.

At the Beijing Railway Station, several cars were parked at the passenger exit, and several soldiers were waiting.

After receiving Peng Shilu and his group, they originally wanted to take them directly to the guest house, but Zhao Renkai and the others wanted to see Chen Guohua immediately.

However, they were tired from traveling and traveling, and it was definitely time for them to take a good rest.

So going directly to the guest house is the best option.

Besides, even if you want to see Chen Guohua, you have to wait and see, right?

Anyway, today is not suitable, because Chen Guohua is not in Zhenhua Research Institute, but in a base outside the city.

The reason why Chen Guohua was at the base was because the drone needed to be tested.

The research and development of large UAVs has been fully launched since the completion of the Spy Dove in September, and has also included technical experts such as Dawn Engine Manufacturing Factory.

And Chen Guohua spent more time participating in it. At the same time, he spent less than half a month to complete the proof process of the basic properties of the solution to the Navier-Stokes equations.

Two of the mathematical tools are of great help in solving many technical problems in drones.

Because of this, Chen Guohua and the others were able to start the first test of a large drone in such a short period of time.

"When the ceiling altitude reached 8,000 meters, we encountered clouds and the remote control communication signal weakened significantly."

"After being fully loaded with a load of 500 kilograms, the battery's cruising range is not as good as the original design data, and the battery needs to be optimized."

"When the distance exceeds fifteen kilometers, the video transmission speed drops significantly, and there is still room for continued optimization."

As the tests were completed one by one, Chen Guohua suddenly understood after seeing the data.

Design and manufacturing are just processes and do not necessarily equate to results.

Although the technical solutions provided by Chen Guohua were perfect, he also strictly supervised the manufacturing of each component.

But there will still be certain flaws in the final result.

Chen Guohua is not too surprised by the current results.

However, when Dai Xizhang, Su Xuewu, Zhu Fanchang, Liu Jinnian, Meng Dehai, An Wenchuan and Xie Dingyi saw it, they all became ecstatic.

Especially Su Xuewu, who came here specially to participate in the first test of a large drone today. He did not expect such a good result.

"Congratulations to Director Chen. You are really amazing. You have actually completed the development of such a large drone in such a short period of time."

Hearing Su Xuewu's congratulations, Chen Guohua smiled slightly and said:

"Secretary Su, this is not only our credit, but also your credit. What's more, we didn't complete it in three months. This project has been started since last year."

The three projects of ordinary drones, turbofan engines and large drones were launched in July last year after Chen Guohua tested Shi Jiayi and eight others.

After the project was launched, Dai Xizhang led researchers from the Ninth Institute over.

Later, researchers from the Fifth Academy and experts and technicians from Liming Engine Manufacturing Factory were added one after another.

Otherwise, how could Shi Jiayi and the other eight of them alone want to complete the project in such a short time?

Don’t even think about it!

"Don't be humble, it's all thanks to you all"

Qiu Zongyue on the side said something, and everyone burst into laughter.

At this time, Dai Xizhang looked at Chen Guohua expectantly and said:

"Director Chen, after the optimization work of the large mission aircraft is completed, can we fully launch the fighter engine project?"

Dai Xizhang has fantasized about this project countless times in his dreams.

Especially when he saw the design drawings Chen Guohua took out, he became even more urgent.

When Xie Ding heard this, his eyes flickered.
