The Military-industrial Scientific Research System of the Academic Master Chapter 250

Chapter 250 The improved JH-7 inspired by Chang Gong

ˆThe dramatic changes in the negotiation situation caught everyone except those familiar with the matter by surprise.

On the other side of the ocean, Director Garvey, who had been re-elected early due to the pressure of public opinion, found his immediate boss overnight. Rodney Slater, the newly appointed Secretary of Transportation only half a month ago, reported the situation to the latter.

“Has the delegation confirmed the contents of that standard?”

Slater, who has only been in his new position for half a month, is still in the process of getting familiar with the work and is obviously unprepared for it.

“The JAA declined to provide us with a complete version of the standard, but there is an outline containing all key elements.”

Garvey's face looked a little haggard. After all, she was also picked up from the big bed in the mansion by her subordinates:

"They increased the original level 3 climate conditions to level 4, requiring all civil aviation aircraft registered and operated in Europe to pass the newly established level 4 icing test. Our people have read the content of the level 4 standard. , the evaluation is that Europeans are completely crazy..."

“Higher than our current standards?”

Slater asked in disbelief.

Garvey, who was sitting opposite him, nodded:

“Much higher. Taking the most intuitive supercooled droplet diameter as an example, the current test standard is greater than or equal to 40 microns, and the level 4 standard they set requires greater than or equal to 100 microns.”

“Is it possible that they are also bluffing?”

"It's unlikely. Although the outline is not complete, it also contains a lot of technical content such as feasibility analysis and risk assessment. After our engineers read it, they determined that at least they were not making it up out of thin air. It should be Really well researched.”

The atmosphere was deadlocked for a while.

“In the past few months, there should be no European models conducting ice tests in the Great Lakes region, right?”

After a few minutes, Slater asked again.

“No, the last European model that completed trials with us was the A340-313, which was completed early last year.”

Although he had only just officially taken office, Garvey was already well aware of these matters.

After answering this question, she almost immediately realized what the other party meant—

How do Europeans do research?

“We cannot rush this matter. It is best to find out the details of JAA first. The bottom line given by Boeing and McDonnell Douglas is that the merger operation must start before the end of this year. So we still have time.”

Although Slater is not familiar with the business of the Department of Transportation, his personal ability is still there, and he quickly provided a relatively stable solution.

Subsequently, in order to reassure his subordinates, he revealed another secret to them:

"In addition, Minister Kanter (Ministry of Commerce) also specifically told me about this matter before. He said that other arrangements have been made. If nothing else, China and Europe will form a temporary alliance to oppose mergers and acquisitions. , should be broken down, or at least weakened, by July this year.”

“If it can be like this, that would be great.”

Garvey looked overjoyed when he heard the news:

"The most troublesome thing at the moment is actually that Huaxia, which has huge market potential, and Airbus, which is developing rapidly, are mixed together. They need each other and have the same interests. This makes it very difficult for us. If we can separate them, the difficulty of defeating them will be different. It will be much smaller.”

ˆThe latest progress in the negotiations between JAA and FAA immediately became the headlines of major media.

The news naturally spread back to China quickly.

However, for the vast majority of Chinese people at this time, airplanes and civil aviation are too far away from them. After all, most people have never seen what an airplane looks like up close in their lives, let alone flying or building an airplane. .

Hence, it has not attracted much attention in society.

But for those who participated in the negotiations and development testing throughout February, this is definitely an event worth remembering.

Hua Xia Aviation people, for the first time, relied on their own strength to have a direct impact on the development of the world's aviation industry.

We are no longer a dispensable force in the aviation industry, but will soon become one of the players eligible to enter and share the pie.

As the work in Haojing gradually comes to an end, the negotiators and technicians who gathered in this central city last month are preparing to return to their jobs.

But Yao Mengna found Du Yishan at this time.

“Teacher, I apply to stay in Institute 603 for a period of time.”

This request made the latter, who was already packing his things, stunned for a moment:

“Tell me what you think?”

"Here at the 603 Research Institute, there is an improvement plan for the JH-7 aircraft. The project has been completed. During this period, I have had some contact with Comrade Tang Changhong, the chief designer of the project, and learned that their ideas for improving the aircraft are similar to what I did in 601 last year. The parts I'm involved in are relatively close, so there should be room for me to play a role.”

Yao Mengna was obviously not impulsive, but had already done some research on the work she planned to complete.

“I know that the Air Force and the 603rd Research Institute want to develop an improved version of the JH-7. In fact, the project application has been pending with the head office for several years.”

Du Yishan stopped packing his things and sat on the chair next to him;

"But as far as I know, this model uses a turbofan 9, which is a purely domestic Spey MK202 engine, and there is no substitute at all. And because the power has not been available, modifications to the aircraft itself have been delayed. ”

Lao Feibao was a model funded by the Navy. Later, the Air Force thought it had good performance and wanted to install it, but many indicators did not meet their requirements, so this improvement plan was created.

It's just that at that time, even the Flying Leopard, which was already in service in the Naval Aviation Corps, could not find enough spare parts to maintain the engine. It was impossible to build a new aircraft, so it was shelved.

Du Yishan is mainly worried that his students will be cheated. But Yao Mengna still insisted:

"Teacher, you are right. This project has indeed been in a state of almost stagnation before. However, the Seiko project launched by Junior Brother Chang at the 410 Factory last year pushed forward the progress of Sibei's localization. Later, we are also preparing to develop the turbofan 9 The above has verified some technologies of the Taihang project, so General Manager Tang is relatively optimistic that some improvement plans will be tested now.”

“Is that so?”

In the past six months or so, Du Yishan has indeed not paid much attention to the situation of the JH-7:

“So, do you know what the next specific plan is for Xiao Tang and the others?”

He pointed to another chair next to him, indicating that he could sit down and speak slowly.

"The 603 Institute and the 172 Factory are now relying on new processing technology to carry out mid-term upgrades for a large number of old JH-7s whose engines are in the first overhaul period. They took this opportunity to coordinate with the military to upgrade two relatively new aircraft from the South China Sea Fleet. airplane."

Yao Mengna also took the opportunity to sit next to Du Yishan:

"The changes currently planned include the introduction of a serrated design and slats on the leading edge of the wing to improve maneuverability in low-altitude flight, equipping the 1553 data bus to upgrade the past centralized fire control program to a bus-decentralized fire control, and upgrade The cockpit structure improves the pilot's visibility and increases the aircraft's ability to receive fuel in the air.”

“In this case, it is indeed the work you did in Shengjing...”

Du Yishan was obviously somewhat convinced.

Seeing this situation, Yao Mengna quickly continued to add:

“More importantly, they are preparing to fully use digital design and manufacturing technology from scratch on this improved model for the first time, and they need manpower to help complete modeling, aerodynamic and structural analysis and other tasks.”

This sentence obviously worked.

“Digital model building is really your strength.”

After thinking for a moment, Du Yishan finally nodded:

“Then if you really want to participate, it's not a bad idea to stay in Haojing for a while.”

However, he then continued:

“But Xiao Yao, there is one thing that I need to tell you.”

"You say."

“If nothing else happens, Xiao Chang will receive a grand prize in two months.”

The topic was suddenly brought to Chang Haonan by Du Yishan:

“I was planning to find a reason for you two to have a holiday together after he comes back from Jinling.”

Especially the second sentence at the end was already an explicit match between two people, which made Yao Mengna blush a little.

"teacher…"

Du Yishan waved his hand and interrupted his student:

　　"I will speak frankly on this matter."

“Everyone now, even if they only know a little bit about the inside story, knows that Xiao Chang's future is limitless. There are already many units that don't even pretend to be pretending, and have begun to openly grab people.”

“So Yu Gong, I hope I can find a way to keep him in Beijing Airlines, and you should be the peer with the closest relationship with him, Yu privately…”

He glanced at Yao Mengna next to him:

“You dare to say that you have no idea about Xiao Chang?”

“I only learned about it in the past two days. This time I went to Jinling to do a project, but there was a senior researcher from the Chinese Academy of Sciences with him. She was very young and female.”

When it was time to talk, Yao Mengna, who was still a little shy, calmed down:

“I know her name is Xu Yang, from the Institute of Computing Technology.”

This answer was completely beyond Du Yishan's expectations.

“Then you still...”

The old academician looked shocked.

“Teacher, it is precisely because of this that I chose to apply to stay in 603 to work on projects.”

Yao Mengna looked at Du Yishan calmly:

“Even if Junior Brother has the idea of finding a partner, do you think that with Junior Brother's character, can I influence his choice by staying next to him?”

One sentence stopped Du Yishan.

Although he had a harmonious relationship with his lover, like most people of that era, he actually got married first and then fell in love.

As a person born in the 1920s, he must admit that he does not understand much about emotions.

“Love is not about two people staring at each other, but looking in the same direction.”

When the word love was mentioned, Yao Mengna's eyes were still a little dodgeful, but her tone was very firm:

“Teacher, although this is difficult, I have to look in the same direction as him.”
