Chapter 713 Let Americans help eliminate wrong answers
“Is there such a thing?”
The latter didn’t even have time to wipe the water stains on his shirt:
“What is he? When can I send it back?”
“I’m afraid it will take a few months.”
Chang Haonan hesitated for a while and then replied:
"He went there as a construction contractor. If he left too quickly, it would arouse suspicion."
"And we will use that piece of debris. Even if it is brought back, it cannot be displayed publicly in a short period of time, and can only be placed in a confidential warehouse to be declassified in the future.”
In fact, the content that Lao Wu contacted him through the company route was all sent back. Encrypted, on the surface, they were usually normal business documents that required translation and the information density was very low. Therefore, the other party only said that they would bring them out when he left the Balkans, without giving a specific timetable.
So Chang Haonan can only make reasonable deductions.
"The exhibition is secondary."
Ding Gaoheng waved his hand:
"I mean, will it have any research value? I mean...invisibility."
“I know that in addition to the appearance of stealth aircraft, the surface of the stealth aircraft must also be coated with absorbing materials to reduce RCS reflection, just like the anechoic tiles of submarines.”
These days, I want to transmit information through confidential means. Taking a picture is not easy, so Chang Haonan has not seen the fragment yet, so he can only give 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 more accurately, help us rule out a wrong answer."< br>
"Well..."
This answer was obviously a bit convoluted, so it took Ding Gaoheng a few seconds to react:
"Huh?"
"Why do you say it excludes a wrong answer?"
Currently, 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 continue to explore in the other party's direction.
“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 the safety of strategic bombers. The mission is very long and often requires dozens of hours of flying, so in most cases it needs to be repainted, which alone costs millions of dollars.”
“And usually to ensure the repainting. If the layer 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, 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..."
"And..."
Chang Haonan took a sip of tea and continued to add:
"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."
After hearing this, Ding Gaoheng also nodded with a look of enlightenment, obviously agreeing with Chang Haonan's statement:
"In other words, there will be a material that can meet the requirements of long life, high tolerance and wave-absorbing performance at the same time?"
Not to mention the special hangars with constant temperature and humidity, the Chinese Air Force does not even have many hangars that can protect it from wind and rain. Most of the aircraft are parked in the open air. In the past few years, due to typhoons, At one time, more than half of the army's available third-generation aircraft were lost.
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 that Chang Haonan just said.
"From the analysis of material theory and current pre-research situation, it is like this."
Chang Haonan naturally knows that this thing must exist, because even the Americans themselves have already changed the technology when developing the F35 route, using a coating material that has less extreme performance on paper but is more worry-free.
Otherwise, I really can’t afford to serve you.
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 on stealth coating maintenance is simply outrageous. It is really You can't find that many people to work with. However, he obviously couldn’t speak too fully at this time, so he added another sentence at the end:
“Of course, for specific operations, we still have to wait until we carry out technical research to get more reliable data. If the material base used on B2 can be analyzed this time, investment in this direction can be reduced and resources can be concentrated on other types of technologies. ”
"Oh..."
This is obviously a bit different from Ding Gaoheng's expectation when he first heard the news.
But 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.
After all, just three years ago, the aviation industry was still worried about the possibility that a domestically produced second- and a half-generation fighter jet would not be able to enter service on time.
Today, three years later, he has actually begun to think about when the troops will be equipped with stealth aircraft.
It’s true that it’s a bit too far.
Ding Gaoheng reflected on himself for a while, and finally came to the conclusion——
The person who caused him to float should still be the one who poured himself tea in front of him.
Furthermore, 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 a domestic product that has not yet been put into service. The status of third-generation machines...
"Ahem——"
Ding Gaoheng warned himself in his heart that as the person in charge of the military industry system, he must not lose his mind under any circumstances.
So, he immediately switched to a slightly more realistic topic:
"Speaking of which, I saw the report submitted a few days ago. Jiang Zhong's forging press will soon be Is it going to be put into production?”
The mind jump is a bit big, but fortunately Chang Haonan has been following up on this matter in Jiangcheng in the past week, so his mind can still keep up:
"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 titanium alloy bulkhead of the J-11B replaces the welding process of the old airframe.”
“Trial production may last one to two years, because I designed a set of core components for that forging press. The life detection and automatic compensation system requires a certain amount of time and processing volume to be verified before the reliability of the system can be determined."
Ding Gaoheng is a semi-precision instrument person, so he immediately raised his eyebrows when he heard this. Maoguang:
"Automatic compensation is similar to that on high-end CNC machine tools..."
"Yes."
Chang Haonan replied:
“This is the inspiration I got from the technology of their competitors when I communicated with engineers at C.B. Ferrari before, which can automatically correct and compensate for the mechanical geometric errors of the equipment and reduce standby time. and maintenance costs. ”
“This technology requires a lot of experience and production data accumulation, so although the development cycle is not long, debugging is very complicated. However, once debugging is completed, this system can be promoted to the general public. On some common presses, we will even be able to make more than half of the profits in the industry by selling industrial control systems, just like those European companies, and let foreigners work for us..."
"Especially The package of agreements 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..."
"Soon it will not be just Europe."< br>
Ding Gaoheng picked up the tea cup, put it to his mouth and blew it gently:
"Don't tell anyone about the internal information from the Ministry of Commerce and Trade."
"After the Allied Forces Operation is over, , the United States has suddenly become more enthusiastic in promoting negotiations on our accession to the WTO, and has taken a step back from us in several areas such as agriculture and communications. If nothing else, the WTO accession matter will be finalized before October 1 this year! ”
