Chapter 1304 I have already designed half of the plane and you are telling me this?

Yang Wei took a deep breath and sat up straight involuntarily.

Tactical fallback.jpg

Since the fourth-generation aircraft is still in the early and middle stages of research and development, the model currently undergoing microwave-related tests in Yudu is just a model made according to the conceptual design.

Although there is symbolic space for the engine, 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...didn't the representative of the 606th Institute say during the last meeting that they planned to postpone the stealth modification of the tail nozzle. In order to ensure the test flight of the prototype, they would first deliver four initial versions of the WS-10G to us?"

As Yang Wei asked, he subconsciously glanced in the direction of Lin Jihong across from him:

"Also, we have been using the large microwave darkroom in Yudu since it was built. They probably haven't conducted a separate test on the reflection area of ​​the tail nozzle, right?"

Gao Wenguang did not answer immediately. There was a sound of turning pages on the other end of the line.

Obviously, the letter sent from 606 was not just a simple one or two pages.

After a while, he spoke again:

"The other party said that they have discovered a new technology that can weaken the reflection characteristics of local radar signals of aircraft, but it needs to be in working condition for the aircraft engine to work properly, and it is also necessary to test the feasibility of maintaining the effect for a long time, so they hope to conduct coordinated testing of the combination in advance..."

This letter was delivered by fax rather than carried by a confidential clerk, so its confidentiality level was limited and many contents related to specific technologies could not be specified.

"Weaken local radar signature?"

Many possibilities flashed through Yang Wei's mind.

But this statement is 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 them that the person in charge of our microwave testing team is in a meeting at the institute today and will be back in Yudu the day after tomorrow at the latest. Ask them to bring some key technical information and detailed testing requirements over there first, and then work with the Electromagnetic Center to finalize the testing plan."

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

Lin and Kong were sitting on the sofa at the other end of the office at this time and could not hear Gao Wenguang's voice on the other side, but even just from Yang Wei's reaction and a few words, it was not difficult to judge the topic of the call.

"Boss Yang, is there any new progress at AECC?"

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

In addition to anticipation and excitement, there seemed to be a hint of nervousness in his tone.

After all, in the past twenty years, China's aviation project research and development has always been dragged down by the power department.

Now if someone else were to wait for them with the engine, the gap would inevitably make people feel a little stressed.

"There is indeed progress, but it's probably not what you think..."

As an old aviation expert, Yang Wei saw through the latter's complicated thoughts at a glance and comforted him:

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

He said, sitting back on the sofa:

"In fact, this time it's related to the electromagnetic testing work in Yudu, so Lao Lin may need 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 that had not yet been bound:

"Mr. Yang, here are the documents you requested."

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

After Gao Wenguang's footsteps faded away, Lin Jihong continued what Yang Wei had not finished saying:

"So... do you need me to go to Yudu right away?"

"Correct."

Yang Wei did not raise his head:

"Tomorrow you will arrange what you have just concluded at the meeting, and then go to Yudu to learn about the specific situation. It is probably related to the details of the engine tail nozzle. By the way, you can also test the radar reflection intensity of several tail fin arrangements from Lao Kong..."

He was almost done with the last sentence, but his voice suddenly stopped.

This change immediately attracted the attention of the other two.

"Mr. Yang?"

Lin Jihong, who was recording the follow-up work arrangements in a 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 contents in a trance.

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

Fortunately, Yang Wei quickly recovered from his initial surprise:

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

He took a deep breath and gently dropped the documents in his hand onto the coffee table.

Now, Lin Jihong finally saw it clearly——

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

……

What Yang Wei didn't expect and was a little disappointed was that Chang Haonan himself did not show up in Yudu.

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

"Mr. Chang's project is currently at a critical stage of research and development, and I have some other things to do at home, so I can't leave for the time being..."

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

However, just after turning 180 degrees, without even turning the page, 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 cloaking?"

This is what the first two shouted in unison.

Then they looked at each other, and as expected, they saw joy in each other's eyes.

Just two days ago at a technical seminar, they were still making painful decisions on how to resolve the conflict between aerodynamics and stealth.

Lin Jihong, in particular, was even prepared to compromise on the design of some locations.

As a result, just when he had prepared himself mentally, someone told him that he no longer needed to consider some details of invisibility?

Yang Wei had similar thoughts.

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

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

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

Of course, he also saw the shocking keyword "plasma stealth".

But the next line that followed was even more shocking:

"You're going to start the engine in my microwave darkroom?"

When Zhang Pinsheng saw the test requirements, he felt a blackout before his eyes and was afraid that his blood pressure would rise to the limit.

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 we must start the engine first, and then the corresponding magnetic control equipment, before we can carry out subsequent tests..."

"No, this is absolutely not possible!"

Zhang Pinsheng refused resolutely:

"The large microwave darkroom was converted directly from a hangar. Precision electromagnetic wave-absorbing cones were installed around the inner walls, and the test process was fully enclosed... If an engine was allowed to work inside, the entire facility would be scrapped before a round of testing was completed!"

Such a fierce reaction also pulled Yang Wei and Lin Jihong out of their joy:

"Yes, Mr. Liu..."

The former looked a little dignified:

"Except for the microwave darkroom's tolerance, our test model is a real model. Only the size and appearance are restored 1:1. There is no internal space structure. At most, we can only install the engine inside... If we want to start it, we need to install additional fuel supply, air supply and control equipment outside, which is impossible to complete in the microwave darkroom..."

"..."

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