"Is there such a thing?"

The latter didn't even have time to wipe the water stains on his shirt:

"When will he be able to send it back?"

"I'm afraid it'll be a few months."

Chang Haonan hesitated for a moment and then replied:

"He came there as a construction contractor, and if he left too soon, it would be suspicious."

"And even if we get that piece back, it will not be possible to display it publicly in a short period of time, so we can only put it in the secret warehouse and wait for it to be declassified in the future."

In fact, the content sent back by Lao Wu through the enterprise route was all encrypted, and on the surface it was usually some normal business documents, which needed to be translated and the information density was very low, so the other party just said that he would bring it out when he left the Balkans, and did not give a specific timetable.

"This technology is very experienced and the accumulation of production data, so although the development cycle is not long, it is very complicated to debug, but once the debugging is done, this system can be promoted to most of the common presses, and then it can even be the same as those European companies, by selling industrial control systems to earn more than half of the profits in the industry, so that foreigners can work for us......"

It's a bit floating.

In these years, it is not easy to transmit a picture through confidential means, so Chang Haonan has not seen the fragment until now, and can only give some generalized judgments based on Lao Wu's text description:

"Yes, there must be, at least we can analyze what kind of substrate material is used in the other party's stealth coating, and give us a reference in our thinking...... Or more accurately, rule out a false answer. ”

"Yes."

"From the analysis of materials science theory and the current pre-research situation, it is like this."

"Oh......"

"Automatic compensation is similar to the ...... of high-end CNC machine tools"

Chang Haonan naturally knew that this thing must exist, because even the Americans themselves had changed their technical route by the time of the development of the F35, and used coating materials with less extreme but more worry-free performance on paper.

Ding Gaoheng waved his hand:

"The trial production may last one to two years, because I designed a core component life detection and automatic compensation system for that forging press, and it takes a certain amount of time and processing volume verification to determine the reliability of this system."

"And ......"

But on second thought, it's better to have a reference than nothing, the current situation is much better than expected at the beginning, and it seems that you shouldn't be greedy enough to swallow the elephant.

Ding Gaoheng reflected on himself a little, and finally came to the conclusion -

"The plane was burned and then bombed, and the specific properties and structure of the coating material must have been changed beyond recognition, even if you want to reverse engineer it...... The feasibility is not too great. ”

"According to current public reports, the stealth coating used by the Americans is very delicate, take the B2 as an example, it needs to maintain the coating after each mission - considering that the mission time of strategic bombers is very long, and they often have to fly for dozens of hours, so in most cases they have to be repainted, and the cost of this alone is millions of dollars."

This is obviously a bit different from Ding Gaoheng's expectations when he first heard the news.

"Hmmm......"

"And in order to ensure that the coating does not fail, the aircraft must be parked in a special hangar with constant temperature and humidity, and even if it does not take off, it must be regularly inspected and maintained...... In short, in terms of the objective conditions of our country, it is okay to study it in the laboratory, but if you want to make samples or even put them into use in large quantities, this kind of nature is definitely not possible......"

Only a few airfields in the north have forts that were built during the war readiness period, but they were only planned to stop the J-6 and J-7, which obviously did not meet the requirements that Chang Haonan just said.

"Soon it's not just Europe."

"Huh?"

Chang Haonan took a sip of tea and continued to add:

Now, three years later, he has begun to think about when he will be able to equip his troops with stealth aircraft.

Not to mention the special hangars with constant temperature and humidity, the Huaxia Air Force now does not even have many hangars that can shelter from the wind and rain, and the vast majority of aircraft are parked in the open air; a few years ago, because of a typhoon, more than half of the available third-generation aircraft of the whole army were lost at one time.

Ding Gaoheng also nodded with a look of sudden realization after hearing this, obviously agreeing with Chang Haonan's statement:

"In other words, there will be a material that meets the requirements of long life, high resistance and absorption at the same time?"

"I know that in addition to the appearance, stealth aircraft should also be coated with absorbing materials on the surface of the fuselage to reduce RCS reflection, just like the silencing tiles of submarines."

"This was inspired by the technology of their competitors when I was talking to the engineers at C.B. Ferrari in the past, which automatically corrects and compensates for mechanical geometrical errors of the equipment, reducing standby time and maintenance costs."

After all, only three years ago, the aviation industry was still worried that a domestically produced second-and-a-half-generation fighter might not be able to enter service on time.

"The official production may not be so fast, now only the equipment has been installed, and various subsystems are being tested, if there is no problem, trial production will start at the beginning of next month, and the plan is to build a batch of J-11B titanium alloy partition frames for the 112 factory first, and replace the welding process of the old body."

Moreover, if you really calm down and think about it, because the starting point is too low, although you can hear the news of the rapid progress of various technologies almost every month in recent years, it is still a state of domestic third-generation aircraft that has not yet been put into service......

So, he immediately switched to a slightly more realistic topic:

"Speaking of which, I read the report submitted a few days ago, Jiangzhong's forging press will be put into production soon?"

Therefore, Chang Haonan can only deduce it reasonably.

The jump in thinking is a bit big, but fortunately, Chang Haonan has been following up on this matter in Jiangcheng in the past week, so his brain can still keep up:

Ding Gaoheng is half of a precision instrument background, and when he heard this, his eyes suddenly lit up:

Ding Gaoheng warned himself in his heart that as the person in charge of the military industrial system, he could not lose his mind no matter what.

Chang Haonan replied:

Otherwise, I really can't afford to wait.

Money is still secondary, as long as you turn on the money printing machine, the point is that the frequency of flight and the number of equipment of tactical aircraft are much higher than that of strategic bombers, and the average monthly working hours on stealth coating maintenance are simply outrageous, and it is really impossible to find so many people to work.

However, he obviously can't talk too much at this time, so he added a sentence later:

"Of course, the specific operation, or to wait until the real technical research, in order to get more reliable data, this time if you can analyze the material base used on B2, then you can reduce the investment in this direction, and concentrate resources on other types of technology."

This answer was obviously a bit twisted, so much so that it took Ding Gaoheng a few seconds to react:

At present, the only country that has applied stealth materials is the United States, and according to common sense, even if you don't want to copy it as it is, you should grope in the direction of the other side.

"Ahem—"

"I mean, is there any research value? I mean...... Stealth. ”

"Why do you say rule out a wrong answer?"

The initiator who caused himself to float should still pour himself tea in front of him.

"Exhibitions are secondary."

"In particular, the package agreement signed with Europe this time has almost eliminated all barriers to computer software and hardware trade, which is very valuable for us to go overseas and seize the market......"

Ding Gaoheng picked up the teacup, put it to his mouth and blew it gently:

"Don't tell the inside news from the Ministry of Commerce and Trade."

"After the end of the allied operation, the enthusiasm of the United States in pushing forward our WTO accession talks has suddenly increased, and it has taken a step back from us in several fields, such as agriculture and telecommunications.
