The military-industrial scientific research system of the academic master

Yang Wei took a deep breath and sat upright involuntarily.

Since the fourth-generation machine is still in the early and middle stages of research and development, what is currently undergoing microwave-related testing in Chongqing is only a model based on the conceptual design.

Although there is a symbolic space left for the engine, but if you want to install two real ones...

That is still somewhat difficult.

And it will inevitably delay the progress of subsequent testing.

"I remember... during the last meeting, didn't the representative of the 606 Institute say that they planned to postpone the stealth modification of the tail nozzle. In order to ensure the test flight of the prototype, didn't they have to deliver us four initial versions of the turbofan 10G first?"

As Yang Wei asked, he subconsciously glanced in the direction of Lin Jihong opposite:

"In addition, we have been using the large microwave anechoic chamber in Yudu since it was built. The other party has probably not conducted a separate tail nozzle reflection area test, right?"

Gao Wenguang didn't answer immediately, and there was a sound of turning pages of paper on the other end of the phone.

Obviously, the letter sent from 606 is not just a simple page or two.

After a while, he spoke again:

"The other party's statement is that a new technology has been discovered that can weaken the local radar signal reflection characteristics of aircraft, but it needs to be effective when the aero engine is in working condition, and the feasibility of maintaining the effect for a long time needs to be tested, so I hope Conduct combined collaborative testing in advance..."

This letter was delivered by fax instead of being carried by a confidential officer. Therefore, the confidentiality level is limited, and many specific technical contents cannot be stated.

"Attenuate local radar signature?"

Many possibilities flashed through Yang Wei's mind.

However, this statement is indeed a bit vague, and it is not yet time to make a more accurate judgment.

After thinking for a while, he finally made a decision:

"Tell the other party that the person in charge of our microwave testing team is having a meeting at the institute today and will return to Chongqing the day after tomorrow at the latest. Ask them to bring some key technical information and detailed testing requirements over there. First, we will unite with the electromagnetic The center has finalized the testing plan.”

"Oh, and remember to send that official letter to me..."

Rin Kong and Kong were sitting on the sofa at the other end of the office at this time. They could not hear Gao Wenguang's voice on the other side, but even through Yang Wei's reaction and a few words, it was not difficult to determine the theme of the call.

"Mr. Yang, is there any new progress at Hangfa?"

After Yang Wei hung up the phone, Kong Chengan asked tentatively.

In addition to anticipation and excitement, the tone seemed to be mixed with a trace of nervousness.

After all, in the past two decades, China's aviation project research and development has been caused by the power department holding back the overall department.

Now if someone else is waiting for them with the engine, the gap will inevitably make people feel a little stressed.

"There is indeed progress, but it shouldn't be what you think..."

As a veteran airliner, Yang Wei could see through the latter's complex thoughts at a glance and comforted him:

"Even if Academician Chang had reserved upgrade space for the Turbofan 10, the efficiency would not be so high... Besides, the new model hasn't even been put on the high-altitude platform yet. How could it be possible to start the finalization process like this?"

He said and sat back on the sofa:

"Actually, this time is related to the electromagnetic testing work in Chongqing. It may require Lao Lin to make a special trip..."

At this time, a knock on the door interrupted the conversation between the three people.

Gao Wenguang appeared outside the office, holding a document in his hand that he had not had time to bind:

"Mr. Yang, the documents you want."

Yang Wei took it in his hand, nodded to indicate that the other party could leave, then lowered his head and started reading page by page.

When Gao Wenguang's footsteps gradually faded away and disappeared behind him, Lin Jihong continued what Yang Wei had not finished:

"So... do you need me to go to Yudu immediately?"

"right."

Yang Wei did not raise his head:

"Tomorrow you lay out the things summarized in the meeting just now, and then go to Yudu to understand the specific situation. It is probably related to the way the details of the engine tail nozzle are handled. By the way, you can also test several tail fin layout plans over at Laokong. Regarding the radar reflection intensity..."

The last sentence was obviously about to be finished, but his voice stopped abruptly.

This change immediately attracted the attention of the other two people.

"Mr. Yang?"

Lin Jihong, who was recording the follow-up work arrangements in his notebook, looked to the side curiously.

I saw that Yang Wei had already spread out the document and turned to the last page, and was staring at the content above in trance.

Although he was curious, Lin Jihong couldn't just go over and look at the documents in the leader's hand, so he had to wait for the other party's reaction.

Fortunately, Yang Wei quickly recovered from his initial surprise:

"No, I will go with you the day after tomorrow..."

He took a deep breath and gently dropped the document in his hand on the coffee table.

This time, Lin Jihong finally saw clearly——

Although this letter was sent from Institute 606, in addition to Liu Yongquan as usual, Chang Haonan's name was also marked on the signature column...

…

What Yang Wei did not expect and was a little disappointed was that Chang Haonan himself did not appear in Yudu.

However, Liu Yongquan still brought a test requirement that was finalized by the latter:

"Mr. Chang's project is now in a critical stage of research and development. In addition, there are some things at home, so I can't leave for the time being..."

Check out the 16-9 book bar to see the correct version!

Although he felt a little regretful, Yang Wei also knew that now was not the time to dwell on this, so he quickly entered work mode and took the technical documents from the other party.

However, as soon as the direction was turned 180°, without even turning back, the summary on the first page made Yang Wei, Lin Jihong, and Zhang Pinsheng, the person in charge of the Electromagnetic Center, exclaim at the same time——

"Plasma invisibility?"

This is what the first two shouted in unison.

Then they looked at each other, and not surprisingly, they could see the overjoyed emotion in the other person's eyes.

At the technical seminar just two days ago, they were still making painful choices to resolve the contradiction between aerodynamics and stealth.

Lin Jihong, in particular, has even made plans to compromise on the design of some positions.

As a result, as soon as he had completed his mental construction, someone told him that there was no need to consider some details of invisibility?

Yang Wei had similar thoughts.

Although I haven’t read the specific content yet, if plasma stealth can really be put into use, it will undoubtedly reduce a considerable part of the constraints in the design process, which is equivalent to reducing the difficulty of aircraft development by several orders of magnitude out of thin air.

In addition to the technical benefits, it also makes it easier for him to manage the entire R\u0026D team.

Zhang Pinsheng, who was sitting next to the two of them, looked completely different.

Of course he also saw the shocking keyword of plasma invisibility.

But immediately after, the next line showed something that shocked him even more:

"You want to start the engine in my microwave anechoic chamber?"

When he saw this test requirement, Zhang Pinsheng felt that his eyes were going dark, and he was afraid that his blood pressure would be high.

Liu Yongquan, who was sitting on another sofa to the side, nodded:

"Our plasma source is generated by the working process of the engine, so the engine must be started first, as well as the corresponding magnetic control equipment, before subsequent testing can be carried out..."

"No, this is absolutely not possible!"

Zhang Pinsheng refused resolutely:

"The large microwave anechoic chamber was directly converted from a hangar. Precision electromagnetic absorbing cones are installed around the inner wall, and the testing process is completely enclosed... If an engine is allowed to work inside, it will not wait at all. After one round of testing, the entire facility will be scrapped!"

With such a violent reaction, Yang Wei and Lin Jihong were also pulled out of their joy:

"Yes, Mr. Liu..."

The former's face looked slightly solemn:

"Apart from the microwave anechoic chamber's tolerance, our test model is a real model. Only the size and shape are restored 1:1. There is no internal space structure. At most, the engine can only be installed... If you want to If it is started, it will require additional external installation of oil, gas, and control equipment, and these cannot be completed in a microwave anechoic chamber..."

"..."

For a moment, the atmosphere in the living room fell into a stalemate...
