Chapter 713 Let Americans help eliminate wrong answers

"Is there such a thing?"

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

"When can he be sent back?"

"I'm afraid it will take a few months."

Chang Haonan hesitated for a moment and then replied:

"He went there as a construction contractor. If he left too quickly, it would arouse suspicion."

"And even if we get the fragment back, we won't be able to display it publicly in a short time. We can only put it in a classified warehouse and wait for decryption in the future."

In fact, the content that Lao Wu contacted him through the corporate route was all encrypted. On the surface, it was usually some normal business documents that required translation and the information density was very low. Therefore, the other party just told him to wait until he left the Balkans. It will be brought out together when the time comes, and no specific timetable is given.

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

It is very difficult to transmit a picture through confidential means these days. Therefore, Chang Haonan has not seen the fragment yet and can only make some general judgments based on Lao Wu's text description:

"There must be some. At least we can analyze what kind of base material the other party's stealth coating uses, and give us a reference for ideas...or to be more precise, help us rule out a wrong answer."

"This technology requires a lot of experience and accumulation of production data, so although the development cycle is not long, it is very complicated to debug. However, once debugged, this system can be extended to most common presses, and it will even be able to follow Like those European companies, they make more than half of the profits in the industry by selling industrial control systems, allowing foreigners to work for us..."

However, after thinking about it, it is better to have a reference than nothing. The current situation is much better than expected at the beginning, and it seems that we should not be greedy or insufficient.

It's true that it's a bit too far.

"Trial production may last one to two years, because I designed a core component life detection and automatic compensation system for that forging press. The reliability of this system can only be determined after a certain amount of time and processing volume verification. ”

At present, the only country that has applied stealth materials is the United States. According to common sense, even if you don't want to copy it, you should follow the other party's direction.

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

"and……"

"Why do you say you are excluding a wrong answer?"

"The aircraft was burned first and then bombed again. The specific properties and structure of the coating material must have been changed beyond recognition. Even if you want to reverse engineer it... it is not feasible."

Money comes second, as long as the money printing machine is used. The key is that the flight frequency and equipment quantity of tactical aircraft are much higher than that of strategic bombers. The average monthly working hours for stealth coating maintenance is simply outrageous. There are really not so many people. Come to work.

However, he obviously couldn't speak too fully at this time, so he added another sentence:

"Of course, for specific operations, we still have to wait until we carry out technical research before we can obtain more reliable data. If we can analyze the material base used on B2 this time, we can reduce investment in this direction and use resources Focus on other types of technologies.”

"Oh……"

"Um……"

“This is the inspiration I got from my previous communication with CB Ferrari’s engineers through their competitors’ technology, which can automatically correct and compensate for the mechanical geometric errors of the equipment, reducing standby time and maintenance costs.”

"I know that in addition to the appearance of stealth aircraft, absorbing materials must be coated on the surface of the aircraft body to reduce RCS reflection, just like the anechoic tiles of submarines."

"Correct."

So, he immediately switched to a more realistic topic:

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

Only a few airports in the north have reinforced aircraft forts built during the war preparation period, but they were originally planned to accommodate J-6s and J-7s, which obviously did not meet the requirements Chang Haonan just mentioned.

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

“Soon it won’t just be Europe.”

The person who caused him to drift off should still be the one pouring himself tea in front of him.

"Cough-cough-"

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

"Automatic compensation is similar to that on high-end CNC machine tools..."

"I mean, will it have any research value? I mean...in terms of stealth."

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

This is obviously a bit different from what Ding Gaoheng had expected when he first heard the news.

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

Chang Haonan replied:

Today, three years later, he has actually begun to think about when the troops will be equipped with stealth aircraft.

"It may not be officially put into production yet. Now the equipment has been installed and various subsystems are being tested. If there are no problems, trial production will probably start early next month. The plan is to build a batch for Factory 112 first. The J-11B’s titanium alloy bulkhead replaces the welding process of the old aircraft.”

"According to current public reports, the stealth coating used by the Americans is very delicate. Take the B2 as an example. It requires maintenance of the coating after each mission. Considering that strategic bombers have a long mission, they often It takes dozens of hours to fly, so in most cases it needs to be repainted, which costs millions of dollars alone.”

"The exhibition is secondary."

Ding Gaoheng reflected on himself for a while and finally came to the conclusion——

"Ok?"

After hearing this, Ding Gaoheng also nodded with a look of enlightenment, obviously agreeing with Chang Haonan's statement:

“In other words, is there a material that meets the requirements of long life, high resistance and wave-absorbing properties at the same time?”

Ding Gaoheng is semi-professional in precision instruments, and his eyes suddenly lit up when he heard this:

"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. Even if it is not taking off, it must be inspected and maintained regularly... In short, based on the objective conditions of our country, in the laboratory It’s okay to do research inside, but if you want to make samples or even put them into use in large quantities, this kind of nature is definitely not possible..."

Ding Gaoheng waved his hand:

Not to mention special hangars with constant temperature and humidity, the Chinese Air Force now doesn’t even have many hangars that can protect it from wind and rain. Most of the aircraft are parked in the open air. A few years ago, due to typhoons, the entire army lost more than 100 aircraft at one time. Half of the available third-generation machines.

Therefore, Chang Haonan can only make reasonable deductions.

Otherwise, I really can’t afford to serve you.

Ding Gaoheng warned himself in his heart that as the person in charge of the military industry system, he could not lose his mind under any circumstances.

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

"From the analysis of material science theory and current pre-research situation, this is the case."

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

"Please don't share the internal information from the Ministry of Commerce and Trade."

"After the Allied Forces Operation ended, the United States suddenly became more enthusiastic in promoting negotiations on our accession to the WTO, and took a step back with us in several areas such as agriculture and communications. If nothing else, we will be able to complete the negotiations before October 1 this year. The matter of joining the WTO is completely finalized!”
