The military-industrial scientific research system of the academic master

Chapter 1415 High-end services often require the easiest way to provide them...

Taking advantage of the time Yang Jie introduced, Charles Kahler, an engineer from BAE Systems, suddenly raised his hand:

"Sorry, I feel a little dizzy, maybe it's because it's too hot here... Can I vent some air?"

Although anti-static clothing has added double coatings inside and outside the fabric to ensure the effect, it is indeed very poor in breathability, but after all, it does not seal people tightly like chemical clothing.

Therefore, if you suddenly make such a request at this moment, you obviously have other plans.

For example, take the opportunity to observe the layered structure and fixed form of the shielded shell.

Although several European countries currently have no relevant plans to build similar equipment, as engineers, whether from the perspective of planning ahead or simply satisfying their own curiosity, they always want to see more things.

Yang Jie only felt a little funny in his heart. After all, when he went to Moscow with his team for inspection, he used similar methods to check the coating hanging form of the wave absorbing tip cone.

In the early years, large microwave darkrooms used combined splicing shells similar to small laboratory devices. A large number of screws, bars and pads were required during the installation process, which inevitably affected the shielding effect.

Therefore, in order to pursue a relatively clean microwave environment, the entire space must be strictly sealed during work, and a special air conditioning system will generally not be installed.

Therefore, if you want to ventilate in a non-working state, you basically do it by opening the waveguide window or even opening the door directly.

Either way, it is equivalent to opening a gap visible to the naked eye on the wall.

There is an opportunity to observe the installation details from the cross section.

Obviously, Mr. Kahler did a lot of homework before coming.

But the information obtained is a bit outdated—

As time goes by, the welded shell process used by the new generation of equipment has long since disappeared.

Its ultra-high and ultra-wide main structure uses welding to reliably rely on the civil steel columns and steel beam frames on the outside of the shell, so that the required exhaust passages can be reserved before leaving the factory without affecting the shielding efficiency.

Actually, he can't blame him.

After all, in the past decade, only China has built a new large microwave darkroom, and those past information, whether from the United States or the Soviet Union, cannot reflect this.

"Okay, Mr. Kahler."

Yang Jieqiang held back his smile and nodded, then took out an exquisite remote control from his pocket:

“I’ll increase the ventilation of the air conditioner, hoping to make you feel better.”

Sure enough, after hearing this sentence and the buzzing breathing sound that followed, Kahler's expression froze on his face.

At that moment, he laughed even worse than crying:

"Thanks…"

Liu Yongquan, who had been following the team at the end, had not interfered in the end, but at this time he still couldn't understand the situation. He couldn't understand that someone wanted to take the opportunity to make trouble, but he was silently criticized and couldn't help but cover his mouth and laugh.

Thirty years from the east to the west, and now it is finally your European turn to experience this feeling.

Fortunately, everyone is still a partnership after all, so the scene is not ugly.

"Next, we will show the basic process of RCS near-field testing. Of course, for everyone's health, the transmitting antenna will not enter work... Please pay attention to the position under your feet and be sure to step within the green area."

Yang Jie said as he came to the door and pressed an inconspicuous button next to him:

"RCS near field 2 requires the implementation of a test preparation process."

Under good microwave shielding, any portable wireless device cannot work properly and can only be contacted through a fixed communication system.

And at this moment, almost every member of the tour group had his eyes glowing.

Especially Kahler, who was a little embarrassed just now, had a 180° face change.

Under the slightly funny expression, there are also some sadness that is not worthy of being told by outsiders.

“The control room received, test preparation process.”

In the speaker that was not sure where it was set, a response from the control room rang.

Of course, no one is responsible for translating this communication.

So, someone soon came to Edsteiner, who was staring at the far-field five-axis turntable. Because the latter came to China too many times, he was the only person in the entire team who could communicate normally in Chinese.

"Charles, what were they just talking about?"

Edsteiner then came to his senses:

"Oh... I just let the control room prepare for relevant details, without mentioning any useful details..."

Soon, accompanied by a humming sound of the drive motor, the near-field 5-axis turntable and the near-field scanning frame moved from the guide rail to the corner of the wall. Then, on the ground outside the green area, many blue conical bodies like the ceiling and the wall also rose, hiding the translation guide rails well. At the same time, the transmitting antenna and the receiving antenna quickly adjusted the angle, and synchronized the white RCS turntable located in the center of the entire room.

The visitors watched the whole room in amazement like Transformers, completing the form transformation in less than a minute.

"Full... fully automatic?"

Kahler subconsciously blurted out in shock.

As an engineer at BAE Systems, he has also seen Lockheed Martin's similar engineering facilities during his participation in the JSF project.

However, the entire preparation process needs to be completed manually, especially after the model to be tested is installed on the RCS rotary table or the five-axis rotary table, the ground wave absorbing cone that was removed before is installed back. The entire process takes about several hours to several days.

And now, it all happened just between a few breaths.

The newest ⊥Xiao⊥Speak⊥Send⊥Six⊥9⊥Book⊥⊥⊥⊥Back⊥⊥⊥⊥!

Correspondingly, the testing efficiency may be improved by dozens of times.

It’s no wonder that the Chinese were able to come up with a decent stealth aircraft in such a short time.

If someone had questioned the performance of the No. 2001 verification machine before this, then now, more things have become -

Will the testing capabilities of this facility be a bit overflowing for Huaxia itself?

Edsteiner, who is more familiar with China, spoke directly:

"Mr. Yang, does this preparation speed mean that the entire facility can complete multiple rounds of RCS testing in one day?"

Such a straightforward way of asking questions even scared the other people on the tour group.

But in fact, Yang Jie has been waiting for this problem for a long time.

It was just to act more like a little more, so I deliberately made a hesitant look and exchanged glances with Liu Yongquan in a pretentious manner.

It took a few seconds before I felt as if I had obtained permission from the latter, I breathed a sigh of relief and replied:

"Yes, in theory, the cycle from preparation to completion of data acquisition for each round is about 2.5 hours. In fact, considering the additional inspection and confirmation, it will take about 4-5 hours to be extended. Of course, such precision equipment also has maintenance cycles. On average, 60-70 sets of tests should be completed every month."

Liu Yongquan actually doesn't know much, but according to the plot, it should be his turn to speak at this time:

"But in most cases, we actually do not have such heavy testing pressure. After all, the design work of an aircraft is very complicated, and time is required for other aspects. Therefore, only 33 sets of tests have been conducted in a month, and there is still almost half of the window period..."

If the previous parts are still paving the way.

Then, it can be considered explicit here.

Europeans may no longer have plans to develop a serious fourth-generation fighter jet, but should stealth drones be done? Should I do the stealth scrubbing of the existing models?

Even if you don’t want it, you will also need a microwave dark room to study anti-stealth and radar remote sensing in the future.

You can't always use laboratory-level facilities to make do with it, right?

Now Americans are unwilling to open up facilities, and the Russians are not very good at facilities themselves, and we have a margin of more than 20 sets of tests every month.

There are more than 20 groups, which is indeed quite a lot for a user, and they can’t be used up at all.

But if everyone competes and distributes it to each user, there must be a first and then arrive.

As for the leak you said?

Stop making trouble, let’s learn about the seller’s market?

Look at where can I use the microwave darkroom that can be paid now?

This is the latest next-generation technology in the 21st century. Are you afraid of leaking secrets?

If you don’t buy it, hurry up and stay there, some people behind you want to queue up.

So, after saying this sentence.

The others are fine.

But the atmosphere between Kahler and Edsteiner, who were more harmonious just now, was instantly not very good.
