The military-industrial scientific research system of the academic master.

Chapter 43 New Modification

The 611 Institute acted very quickly. Two days later, Chang Haonan met Lu Yuying who rushed to the capital by plane.

After the team meeting yesterday, he opened the system and took a look and found that the scientific research points had become 36 points.

Obviously, although he was talking about things that had been done before, the audience below was no longer four professors but most of the college, including many influential professors, so he still received 4 scientific research points.

And Lu Yuying, who is sitting in front of him now, although there is only one person, his influence is no less than that of the hundreds of people yesterday combined.

In fact, when Chang Haonan received the call from this person yesterday morning, he even felt for a moment that he was not a liar.

After all, his paper hasn't been published yet.

Even if I later figured out the whole story, I still felt a little confused.

The name Lu Yuying may not be well-known outside, but it is well-known within the aviation system, especially in this era.

Since the J-7C/D model is not considered a success, and Song Wencong has served as the chief designer of Project 7, he is currently the person with the most say in the J-[-] series of aircraft models.

Although the purpose of publishing the paper was to be seen by people within the aviation industry, Chang Haonan never thought that the first person who contacted him would have such weight.

"Hello, Chief Master Lu."

"Comrade Xiao Chang, nice to meet you."

After meeting, the two shook hands and then sat in a small conference room specially arranged by the college.

Although Lu Yuying has a high status in the aviation system, his identity is sensitive after all, and his itinerary is difficult to publicize. Therefore, the only people on Beijing Airlines who know about this matter are Du Yishan and Tang Lintian.

The latter really didn't expect that only ten hours later, he would see this student again on such an occasion.

In fact, even Tang Lintian didn't need to know, but Du Yishan suddenly said last night that he was rushing to Shengjing for a meeting, so he left the reception to him.

Since we had already communicated on the phone yesterday, Chang Haonan came prepared.After sitting down, he took out several floppy disks containing engineering documents from his school bag, as well as the complete calculation instructions that were handed in first.

Upon seeing this, an assistant next to him opened the laptop and inserted the first floppy disk, while Lu Yuying put on his glasses and started flipping through the paper document.

"Comrade Xiao Chang, I'm a little curious. Since you deliberately concealed part of the content in the article published in the journal, why did you bring it out so readily now?"

Lu Yuying raised her head slightly, looked at Chang Haonan sitting opposite and asked.

“It is no boast to say that the design methods I reflected in these engineering documents should be considered relatively advanced in the world, so at least in a short period of time, we cannot just let foreigners learn them casually. "

This is not the first time Chang Haonan has been asked similar questions, so he answered almost without thinking:

"And now that you are asking the question in person, Chief Master Lu, I will have no reservations. After all, these studies are originally intended to enable China to build better aircraft."

After hearing these words, Lu Yuying's slightly narrowed eyes suddenly widened a little.

Don't blame him for being shocked.

Chang Haonan's thoughts would have been normal 20 years ago or 20 years later, but in the mid-90s, it was indeed quite rare.

After a long silence, Lu Yuying nodded: "You are worthy of Comrade Xiao Chang to have such an awareness!"

This somewhat lackluster statement made Chang Haonan a little confused. Why did the other party suddenly act like he had known him before?
In fact, since Chang Haonan already knew Lu Yuying's name, when the two talked on the phone yesterday, they introduced themselves very briefly.

In addition, Du Yishan, who is the tutor, did not show up today, so just like Tang Lintian yesterday, Lu Yuying still does not know Chang Haonan's true identity as a student. He always thought that the other party was a young teacher poached from abroad by Beijing Airlines. .And in this year when others are rushing to go abroad, it is natural to choose to return home and show such a high level of awareness.

This is where the slightly strange exclamation just came from.

……

After all, Lu Yuying was very familiar with the J-7 aircraft, and had already conducted some research on the design of the mandibular inlet before this, so it only took about 10 minutes to read the technical documents provided by Chang Haonan.

"Comrade Xiao Chang, the degree of completion of your design... indeed far exceeds my imagination."

"General Manager Lu was very impressed. Although I am very confident in my integrated design of the inlet/cone front body, when it comes to the overall design of the aircraft, it can only be regarded as the beginning. Many details need to be designed." Improve and optimize the hole data, so that..."

Before Chang Haonan finished speaking, Lu Yuying waved his hand:

"I can see this without saying anything, but it's amazing that you can come up with such a preliminary design plan without the relevant hardware. If I hadn't seen it with my own eyes, I wouldn't have believed it. of."

"As for the subsequent work, we in the aviation industry system are not just for a living. Do we have to wait for others to feed us everything?"

Hearing this, Chang Haonan also laughed.

Indeed, in the previous life, without the help of his plug-in, didn't the comrades in the aviation industry build the J-15 2011 years later in 20?

I did underestimate their ability to act just now.

"So, I don't know what your thoughts are on this design plan..."

Chang Haonan asked tentatively again.

Although the initial purpose of using it as a stepping stone has been exceeded, he will never mind getting one fish and two fish to gain more scientific research points and experience points.

Due to lack of relevant experience in the previous life, the J-7FS project actually had a strong experimental meaning from the beginning.

The S in the model name FS means "test".

But now, with the more complete design method provided by myself, I wonder if there is a chance to turn the J-7FS into the J-7F?

"To tell you the truth, I do have a few more designs about the radome, that is, the cone front body, and I would like to ask Comrade Xiao Chang for your opinion..."

In fact, Lu Yuying already had a relatively clear plan in mind when he saw the paper for the first time.

After seeing the engineering documents provided by Chang Haonan, he was even more delighted to discover that the actual performance potential of this design was actually greater than what was written in the paper!
So he had a bolder idea, which was to further increase the diameter of the radome to 600mm to install a new model of pulse Doppler (PD) radar under development.

As for the increased weight, it can be compensated by changing the radome wall structure from a solid half-wave wall to a lighter C-type sandwich.

But considering that in this design, the radome itself is still part of the air intake structure and is responsible for first-level compression of the incoming flow.

So this seemingly small change may affect the whole body.

Only then did I want to ask Chang Haonan for his opinion.

Obviously, Lu Yuying is serious about this model.
