Chapter 249: The improved version of the J-7 inspired by the permanent worker
The dramatic change in the situation of the negotiations took everyone but those in the know by surprise.
On the other side of the ocean, Director Gavi, who had already been turned regular ahead of schedule under the pressure of public opinion, found his immediate boss overnight, and Rodney Slater, the new Minister of Transportation, who was only appointed half a month ago, reported the situation to the latter.
"Has the delegation confirmed the content of that standard?"
Slater, who has only been in his new position for half a month, is still in the process of getting acquainted with the work, and is obviously unprepared for it.
"The JAA refused to show us the full version of the standard, but there was an outline with all the key elements."
Gavi's face was a little haggard, after all, she was also picked up from the big bed of the mansion by her own subordinates:
"They have increased the original level 3 climatic conditions to 4 levels, requiring all civil airliners registered and operating in Europe to pass the newly established level 4 icing test, and our people have seen the content of the level 4 standard, and the evaluation is that the Europeans are completely crazy......
"Higher than our current standards?"
Slater asked, somewhat incredulous.
Gavi, who was sitting across from him, nodded:
"It's much higher, taking the most intuitive supercooled droplet diameter as an example, the current test standard is 40 microns or greater, while they set a level 4 standard that requires 100 microns or more."
"This ...... Is it possible that they are also bluffing? ”
"It's unlikely, although the outline is not complete, but it also contains a lot of technical content such as feasibility analysis and risk assessment, and after reading it, our engineers determined that at least they didn't make it up out of thin air, and it should really have been studied in depth."
The atmosphere was at a stalemate for a while.
"In the past few months, there shouldn't have been any European models in the Great Lakes to do icing tests, right?"
It was only a few minutes before Slater asked again.
"No, the last European model to complete trials with us was the A340-313, which was completed at the beginning of last year."
Although he has only officially taken office, Gavi already knows these things well.
And after answering this question, she also realized what the other party meant almost immediately-
How do Europeans do research?
"This matter can't be rushed first, it's best to find out the details of JAA first, the bottom line given by Boeing and McDonnell Douglas is that the merger operation must be implemented before the end of this year, so we still have time."
Although Slater was not familiar with the business of the Ministry of Transportation, his personal ability was still there, and he quickly gave a relatively safe solution.
Subsequently, in order to reassure his subordinates, he revealed a secret to the other party:
"In addition, Minister Kanter (Ministry of Commerce) has also spoken to me about this before, and he said that other arrangements have been made, and if nothing else, the temporary alliance formed between China and Europe in opposing the merger should collapse by July this year, or at least be weakened."
"It would be great if it could be like that."
Gavi, who heard the news, was overjoyed:
"At present, the most troublesome thing is actually that the huge market potential of China and the rapid development of Airbus are mixed together, they need each other, and the interests are the same, which makes it very difficult for us to do, if we can disassemble it, the difficulty of each break will be much smaller."
……
The latest developments in the negotiations between the JAA and the FAA made headlines in the media immediately.
Naturally, the news quickly spread back to China.
However, for the vast majority of Chinese people at this time, airplanes and civil aviation are too far away from themselves, after all, most people have never seen what an airplane looks like up close in their lives, let alone take an airplane or build an airplane.
Therefore, it has not attracted too much attention in society.
But for those of you who have been involved in negotiations and R&D testing throughout February, it's definitely a big event to remember.
For the first time, the people of Huaxia Airlines have had a direct impact on the development of the world's aviation industry by virtue of their own strength.
We are no longer a dispensable force in the aviation industry, and we will soon be among the players who are eligible to enter the pie.
And as the work in Hokyung gradually came to an end, the negotiators and technicians who had gathered in the central city last month were preparing to leave for their jobs.
But Yao Mengna found Du Yishan at this time.
"Teacher, I apply to stay in the 603 Institute for a certain period of time."
This request stunned the latter, who was already packing his things:
"Tell me what you think?"
"On the side of the 603 Institute, there is a plan for the improvement of the J-7 aircraft, which has been completed, and I have had some contact with Comrade Tang Changhong, the chief designer of the project, during this time, and I have learned that their improvement ideas for the aircraft are close to the part I participated in in the 601 last year, and 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 was going to complete.
"I know that the Air Force and the 603 Institute want to carry out the improved version of the J-7, but in fact, the project application has been hanging on the head office for several years."
Du Yishan stopped packing up his things and sat on the chair next to him;
"However, as far as I know, this model uses turbofan 9, that is, the purely domestic Spey MK202 engine, and there is no replacement at all, and because the power has not landed, the modification of the aircraft itself has been delayed."
The old flying leopard was funded by the Navy, and later the Air Force felt that the performance was good and wanted to install it, but many indicators did not meet their requirements, so there was this improvement plan.
It's just that at that time, even the Flying Leopard, which was already in service with the naval aviation, could not find enough spare parts to maintain the engine, how could it be possible to build a new aircraft, so it was shelved.
Du Yishan is mainly worried that his students will be pitted.
But Yao Mengna still insisted:
"Teacher, you are right, this project has indeed been in a state of almost stagnation before, but last year, Senior Brother Chang engaged in the Seiko plan in the 410 factory pushed the progress of Spey's localization, and later prepared to verify some of the technologies of the Taihang project on the turbofan 9, so Chief Master Tang is more optimistic that now it is time to test some improvement plans."
"Is that so?"
In the past six months or so, Du Yishan has indeed not paid attention to the situation of the J-7:
"Then Xiao Tang, what is their next specific plan, do you know?"
He gestured to another chair next to him, motioning for him to sit down and speak slowly.
"The 603 Institute and the 172 factory are now relying on new processing technology to upgrade a large number of engines to the old J-7 in the first turnover, and they will take this opportunity to coordinate with the army to get two relatively new aircraft from the South China Sea Fleet."
Yao Mengna also took the opportunity to sit next to Du Yishan:
"The changes currently planned include the introduction of a sawtooth 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 centralized fire control program from the past to bus-decentralized fire control, upgrading the cockpit structure to improve pilot visibility, and adding the ability to fuel the aircraft in the air."
"In this case, it's really the job you did in Shengjing......
Du Yishan was obviously somewhat convinced.
Seeing this situation, Yao Mengna hurriedly continued:
"More importantly, they are ready to use digital design and manufacturing techniques from scratch for the first time on this improved model, which requires manual help with modeling, as well as pneumatic and structural analysis."
This sentence clearly played a role.
"Digital modelling is really your forte."
After pondering for a moment, Du Yishan finally nodded:
"If you really want to participate, you might as well stay in Hokyo for a while."
However, he then continued:
"But Xiao Yao, there is one thing that I need to tell you about."
"You say."
"If nothing else, in two months, Xiao Chang will receive a grand prize."
The topic was somewhat abruptly led to Chang Haonan by Du Yishan:
"I was going to find an excuse for the two of you to take a vacation together when he came back from Jinling."
Especially the second sentence in the latter sentence is already a clear match between two people, which makes Yao Mengna blush a little
"Teacher ......"
Du Yishan interrupted his student with a wave of his hand:
"I'll get straight to the point on this matter."
"Now everyone, even if they just know a little bit of the inside story, they know that Xiaochang's future is limitless, and there are already many units that don't pretend to be pretending, and they have begun to reach out and openly rob people"
"So Yu Gong, I hope to find a way to keep him in Jinghang, and you should be the closest peer to him, Yu Zhi......"
He glanced at Yao Mengna next to him:
"You dare to say that you don't have any thoughts about Xiao Chang?"
"I also learned about it in the past two days, this time I went to Jinling to do a project, but there is a senior researcher from the Chinese Academy of Sciences with him, very young, female."
When it was time to talk about it, Yao Mengna, who was still a little shy, calmed down:
"I know that her name is Xu Yang, from the Institute of Computing Technology."
This answer was completely unexpected by Du Yishan.
"Then you still ......"
The old academician looked stunned.
"Teacher, it is precisely because of this that I chose to apply to stay in the 603 project."
Yao Mengna looked at Du Yishan with a calm face:
"Even if the junior brother has the idea of finding a partner, do you think that with the personality of the junior brother, can I always stay next to him affect his choice?"
One sentence stopped Du Yishan.
Although he had a harmonious relationship with his lover and a deep relationship, like most people in that era, he actually married first and then fell in love.
As a man born in the 20s of the 20th century, he must admit that he does not understand much about the emotional aspect.
"Love is not about two people staring at each other, but looking in the same direction."
When the word love was spoken, Yao Mengna's eyes were still a little evasive, but her tone was very firm:
"Teacher, it's hard, but I have to look in the same direction as him."
