The rejuvenation of a great nation: from educated youth to national treasure scientist

Chapter 173 Variable Cycle Engine [Request for Full Order]

"Our Su-27 is the best third-generation fighter in the world! We have just begun to equip our own air force!"

"He actually refused to exchange the chip industry chain?"

Emperor Xun looks very bad now.

Osterlund smiled bitterly: "I heard that they are also researching the third-generation fighter jets, and they should have broken through the technical bottleneck."

"Maybe this is the main reason why they are unwilling to exchange."

Emperor Xun snorted coldly: "I don't believe they can produce a third-generation fighter!"

"Without our help, they can't even start a modern industry!"

"We helped them lay a strong industrial foundation, but they didn't give us anything in return. Instead, they stood against us!"

“It’s so infuriating.”

Emperor Xun was still a little bit upset.

Osterlund thought for a moment and said cautiously: "I think we should pay more attention to practical interests in international exchanges."

"Now, if we continue to quarrel with them, it will do us no good."

"They have a lot of industrial products that we urgently need."

"If we can maintain a friendly relationship with them, it may be more beneficial to us."

"Leader, I have an idea. We can sell them a castrated version of the Su-27 at a relatively low price."

"In this way, they will have a channel to purchase advanced fighter jets, and perhaps they will no longer have to conduct their own research and development."

Emperor Xun pondered for a moment, nodded and said, "You are right, let's give it a try and see if this can be done."

"Alas! I feel that we are actually expressing goodwill, so why can't they be more proactive and take the initiative to improve their relationship with us?"

Ostlund hesitated for a moment, and spoke more cautiously: "Leader, in fact, they support us quite strongly."

"Without their advanced chips, the development of many of our advanced weapons would be problematic."

"They have actually been showing us goodwill."

"I think we should also have a more positive response. If you can take the initiative to visit, and we can have a drink and chat, maybe we can forget our grudges and laugh it off."

"Also, we should treat them equally. We should regard them as our partners instead of always trying to suppress them."

Emperor Xun frowned.

Now Big Bear is actually quite passive, and his strength is also declining.

Mainly due to Yusa's operation, the international oil price fell sharply, even to the lowest point.

Daxiong is now even losing money on selling oil.

This move by Yusa immediately put the big bear, which relied on resource exports, into a difficult situation.

Emperor Xun now also wants to break this dilemma.

"Yes! Long is a respectable partner. We are all brothers, and it is wrong to be so cold to each other for so many years."

Osterlund did not tell him the list that Wang Haoran gave him just now.

Because he didn't know what Emperor Xun's attitude was.

He was also afraid of getting into trouble.

"Leader, I have something here, but I don't know whether I should tell you or not..." Osterlund said.

Emperor Xun said: "What can't be said?"

"Are you still going to hide this from me?"

Osterlund repeated what Wang Haoran had said about the traitor.

"Leader, we trusted Yusa a little too much. In fact, their superficial kindness to us is all to confuse us."

"They just wanted to kill us the whole time."

"We must take drastic action to eliminate all those traitors!"

"Otherwise we'll be in danger!"

Ostlund said this with great courage.

Emperor Xun frowned even more tightly.

Ostlund also became increasingly uneasy.

Because the people he just mentioned are all very important figures.

They actually have a very good relationship with Emperor Xun.

If they couldn't gain the trust of Emperor Xun, they wouldn't have been able to climb so high.

So, Osterlund was taking a great risk.

"Is it possible that the map is a spy?" Emperor Xun murmured.

“You can look into it,” Ostlund said.

"I think there's a real problem with him."

"Also, Wang Haoran also said that we should not tolerate the existence of the so-called opposition! Because the opposition is nothing but dogs raised by Judas!"

"If they can jump and they don't get punished, the consequences will be dire."

Emperor Xun said, "I'll think about it."

"Well! After you go back, you must continue to show kindness and continue to enhance the friendship between us and the dragons."

……

The year 1980 passed quickly.

In early January 1981, the first domestically-produced variable cycle turbofan engine developed under the leadership of Wang Haoran was finally assembled.

That’s right, the first domestically produced engine developed by Wang Haoran was of high difficulty.

He developed a variable cycle engine.

The so-called variable cycle engine refers to the process of adjusting the parameters of the thermodynamic cycle by changing the geometric shape, size or position of some components when developing aircraft engines, such as the compression ratio, turbine inlet temperature, air flow and bypass ratio, etc., so as to change the engine cycle working mode, so that the engine can be in the best working state under a variety of different flight conditions.

In this way, the variable cycle engine can demonstrate excellent performance in subsonic, transonic, supersonic and hypersonic flight conditions.

It can be said that variable cycle engines are the development direction that many aviation industry powers dream of.

But as of now, there is no mature and easy-to-use variable cycle engine in the world.

Even Jusa couldn't figure it out.

But the advantages of variable cycle engines are also obvious.

It can significantly reduce fuel consumption, significantly increase hovering time, and significantly increase aircraft range.

A mature variable cycle engine can make a fighter jet a truly all-weather super fighter.

The aircraft engine is the heart of a fighter jet.

The development of the engine means that the biggest problem has been solved.

However, after developing the engine, there is still a lot of work to be done.

Because a lot of tests must be done to ensure that the aircraft engine is safe and reliable.

There are more than ten types of engine tests.

For example: endurance test, that is, the aircraft engine needs to run for at least 150 hours at different power and temperature conditions, especially testing under hail and severe cold conditions. The purpose of this test is to test the robustness of the aircraft engine under extreme flight conditions.

There is also a bird swallowing experiment, which is to shoot bird carcasses into the running engine at a certain speed and angle to verify whether the engine can withstand the impact of a flock of birds when running at full power...

Wang Haoran personally presided over the comprehensive testing of the engine.

The entire testing process lasted more than a month.

Finally, all the rigorous tests were completed successfully.

The variable cycle engine developed under the leadership of Wang Haoran passed the test and its quality is quite amazing.

During the aircraft engine testing process, Zhang Mingxiang, the head of the Third Machine Department, came to inspect the work almost every few days.

The day when the comprehensive engine testing was completed was February 1981, 2.

There are only a few days left until the Spring Festival.

After hearing the news that the aircraft engine had been fully tested, Zhang Mingxiang immediately went to the test workshop.

"Comrade Haoran, what are the overall test results like? Are there any major improvements needed?" Zhang Mingxiang asked.

Wang Haoran smiled and said: "Overall, it is still very excellent. The experimental conditions we set up are very strict!"

"Our engine has passed all the rigorous tests and can continue to work even in the harshest environment..."

Wang Haoran gave Zhang Mingxiang a series of test parameter data.

After reading it, Zhang Mingxiang was surprised and delighted.

"These parameters are much better than the F100 turbofan engine of Jusa we saw!"

Wang Haoran smiled and said, "It can be said that the F100 engine of Jusa is a relatively poor engine. Its performance is very unstable and has significant defects."

"Our engine can easily crush it!"

"It's not even on the same level as ours." "Our engine can fly at low altitudes, hypersonic speeds, and subsonic speeds. The thrust-to-weight ratio can reach 10.9, and the maximum thrust can output more than 18 tons! It should be considered the most powerful aircraft engine in the world."

Zhang Mingxiang said: "Now that we have built the engine, should we speed up the production of the aircraft?"

"People all over the country are eagerly waiting for this aircraft!"

Wang Haoran smiled and said, "Now that the engine has been solved, there won't be any more problems."

"Xi'an Aircraft Industry Corporation is already building the fuselage of the aircraft."

"I think that after the Spring Festival, around early March, we should be able to see the first J-3 being built."

"By that time, it will be spring and the flowers will be blooming, so we can carry out flight tests."

"The test flight will be a high-intensity flight test, and we will try to complete the test flight work within three months."

Zhang Mingxiang slapped his thigh and laughed, "Okay! I'll celebrate your success then!"

"Comrade Haoran, there is one more thing I cannot hide from you. Daxiong is actively trying to sell us the Su-27 fighter."

"Moreover, the price they offered was very low, nearly half the price that Jusa offered us for the F16."

As mentioned before, Yusa also tried to sell their F16 to us.

But their asking price was a bit too high.

Moreover, they put forward various unreasonable conditions.

Jusa is trying to get us to give up our own military production and import it entirely from them.

How could this condition be agreed to?
Therefore, Longguo did not introduce the F16.

Wang Haoran asked: "What do the leaders mean?"

"The Su-27 is indeed a pretty good aircraft. It would be nice if we could buy a few to compare them."

"But I guess even if they are willing to sell it to us, they will definitely castrate it."

"The Su-27 we can get is estimated to have a combat capability of only 8% of their own."

Zhang Mingxiang nodded thoughtfully and said, "Then I understand."

"Then let's buy six. We've made a lot of money from them in the past year or two, so it's time to buy something from them."

……

After Zhang Mingxiang returned to his unit, he communicated and reported to the designer.

The leader said to Zhang Mingxiang: "Then let's do as Comrade Haoran said!"

"Since our third-generation advanced fighter jets are about to be launched, buying too many Su-27s would be a sheer waste!"

"First buy six and study them."

"Haha! I never thought of that! One day we can export a large amount of high-tech products to Big Bear and earn their money!"

The designer is happy with the current situation.

Daxiong now imports large quantities of chips, computers, televisions and other products from Longguo every month.

This allowed Longguo to earn a large amount of foreign exchange.

Well, when doing business with Big Bear, Longguo also only accepted rice and knives, and not their rubles.

There is no way, because the current ruble value is unstable.

After receiving instructions from his leader, Zhang Mingxiang turned around and contacted Consul Osterlund.

Because it was Osterlund who took the initiative to contact Zhang Mingxiang and wanted to sell the Su-27 to Longguo.

When the call was connected, Osterlund asked anxiously, "Comrade Zhang, how many Su-27s do you want to purchase?"

"You know, our Su-27 production capacity is not very large at the moment. If you need to purchase a large number of products, I will need to coordinate."

Zhang Mingxiang smiled and said, "Thank you for your support."

"We plan to send a delegation to inspect the area after the Spring Festival, and then we can decide how many aircraft to buy."

Osterlund didn't expect that the other party would still want to conduct an investigation.

However, this only shows that the other party is very cautious.

"Okay, okay! You're all welcome to come then!"

"Yes! Well, we also hope to invite Comrade Wang Haoran to visit Daxiong. Please pass on the message."

Zhang Mingxiang immediately became a little alert. He wondered what this invitation meant.
Wang Haoran is now the national treasure of Dragon Country.

National treasure-level scientists enjoy the highest security measures.

Although the country has not made it clear, there is basically an unwritten rule: for safety reasons, Wang Haoran is not approved to visit abroad.

"Haha! Comrade Haoran is very busy now. I estimate that he has no time to go abroad for inspection."

This was Zhang Mingxiang's tactful refusal.

Ostlund also felt a little regretful: "Oh! Well! In our country, he has a very high reputation. If he can visit Big Bear, he will definitely receive the highest level of reception."

"Comrade Zhang, I have an unwelcome request. We hope to send someone to study with Wang Haoran. Do you think it's okay?"

Zhang Mingxiang thought to himself, is this something I can decide?
"Oh, then I'm afraid we need to discuss it with Comrade Haoran. If he agrees, there shouldn't be any problem. Wait a moment, we will give you a reply."

……

The national postgraduate entrance examination in January has ended. There are more than 5 candidates nationwide who applied for Wang Haoran's postgraduate and doctoral programs.

By early February, the scores for the postgraduate entrance examination were finally released.

This is the first national unified examination for postgraduate students.

Originally, not many people paid attention to the postgraduate entrance examination.

However, because Wang Haoran became the youngest master's and doctoral supervisor at Beijing Institute of Technology and began to recruit students, this postgraduate examination also attracted much attention.

After the scores came out, the thing that everyone is most concerned about is: there are so many people applying for Wang Haoran's postgraduate program, who will be the lucky one to stand out and become a student personally trained by Wang Haoran.

As we all know, the postgraduate examination is divided into unified examination papers and professional course examination papers.

The unified examination paper is the same nationwide, generally including politics, English and mathematics.

For professional courses, the examination papers are set by the teachers.

Many young scientific researchers and students from prestigious universities participated in this postgraduate examination.

These people's level of knowledge and so on are all quite solid.

Many people are eager to try and are determined to become Wang Haoran's personal disciples.

The difficulty of the national examination was just average, and everyone felt that they did quite well.

However, when it came time to take professional exams, many people who wanted to take Wang Haoran's postgraduate exam were confused.

Because the test paper that Wang Haoran personally prepared was actually a hodgepodge, involving multiple disciplines and fields such as electronics, mathematics, chemistry, physics, mechanics, aerospace, aviation, etc.

All the questions he asked were practical, involving the actual application of knowledge and practical operations.

For example, calculating trajectory, programming calculations, chip and circuit design, etc.

You say it is difficult, but actually it is not that difficult.

But it is a great test of flexibility of thinking and the ability to apply knowledge flexibly.

How can you get high scores without good creative thinking?

That was just a dream.

The professional course topics set by Wang Haoran almost made most of the candidates collapse.

After coming out of the examination room, almost everyone had a sad face.

Some people even complained: How can such difficult questions be differentiated?
It is estimated that most people’s scores will be very poor.

When the test scores came out, those who had applied to be Wang Haoran's graduate student were wailing.

Because, the professional courses have a total of 200 points, and it is rare to get 100 points.

In Wang Haoran's office, Qiu Bojun, who had recently been serving as Wang Haoran's assistant, walked in with a stack of papers.

"Uncle Haoran, I sorted it out. Among those who applied for your postgraduate examination this time, there are 300 people with a total score of more than 84 points."

"There are 100 students whose professional course scores are above 19 points."

"The highest score in the professional course is 171 points."

"Oh, this student who scored 171 points in his major course got a total score of 408.5 points!"

"She is your wife, Xiao Lijuan."

Qiu Bojun reported to Wang Haoran.

Wang Haoran took the statistical results with a smile and said, "In fact, the professional course topics I set are not really too difficult. It's mainly because everyone has not seen similar topics before, so they are a little confused."

Qiu Bojun scratched his head and said, "There is another point: the knowledge involved is really too broad. Most people cannot learn so many fields."

"I, I also tried to do it, but I only got a little over 150 points."

Wang Haoran looked through the statistics and said, "There still has to be some differentiation!"

"If everyone gets high scores and I have to interview more than a thousand people at once, I won't have anything to do. As for the 100 people who scored above 19 in their professional courses, I'll just have them come over for the interview."
