Invincible Smart-Guy System - Chapter 411 flagship of national defense industry (I)

For China’s new generation fighter j-20, the j-20 has been rectified many times over the years, and has been finalized as a whole and started to be mass produced in small quantities. So far, the number of equipped troops has reached 80. However, the air force is still in the trial stage of j-20. The military is gradually exploring the j-20 and gradually feeding back various problems. Most of the problems point to one That’s under thrust.

The so-called thrust deficiency means that the j-20 itself is a heavy-duty fighter, with a total weight of more than 35 tons under the maximum load. However, the configuration of two engines, whether using the Taihang engine in China or the latest al31f modification in e country, cannot achieve a thrust to weight ratio of more than 1 as a whole. Even if it is the latest al31f modification, the thrust of a single engine is only nearly 13 tons The total thrust of the two engines is only about 25 tons at most, 25 tons at most, and 35 tons at most. In most cases, the aircraft can’t achieve a thrust to weight ratio greater than 1. If you want to have enough maneuverability, you have only two options, either, reduce the ammunition load, or reduce the fuel load.

Reducing the ammunition load means reducing the combat effectiveness, reducing the fuel load means reducing the endurance. This has always been a headache and a very difficult problem for the military. The root of this problem is nothing more than the lack of better engine technology. However, the United States is far ahead in this field. The inclusive F119 series engine has a thrust at least higher than that of e-country The engine is 40% higher.

According to the parameters of the j-20 and the general situation of the top fighters at present, Zhang Yunfeng and Xiao Er jointly determined an index.

The thrust of the new military engine developed by Dongchen should be at least 18 tons. In this way, if it is equipped on the j-20, even if the aircraft is fully loaded, it can obtain a thrust to weight ratio greater than 1 through the way of adding force, so that it has stronger maneuverability.

If the afterburner is not used, the thrust of the single engine is about 14 tons, which is enough to cope with the use of fighter aircraft most of the time. After all, fighter aircraft do not need more than 1 thrust weight ratio most of the time. But once in war, the aircraft with large thrust weight ratio, in terms of mobility and flexibility, is far more than the aircraft with small thrust weight ratio, which alone determines the battle The comprehensive combat power and the ability to get out of trouble.

After confirming the design scheme, Zhang Yunfeng asked Xiaoer to quickly give the processing design drawings of all key parts and send them directly to Jiangcheng. The mold factory in charge of Zhang Xingmin, his father, has already possessed the world’s leading high-precision processing technology, but the mold processing is for the future mass production, and Zhang Yunfeng is for the best Quick out of the prototype, let Xiaoer directly use the high-precision machining center located in Jiangcheng to make a single processing and manufacturing of each new part, hoping to deliver the prototype to the military as soon as possible, which will be verified by the military.

Although Zhang Yunfeng is in Zhonghai at the moment, the sophomore can directly use the network to remote control the high-precision machining center located in Jiangcheng. All the production and processing links in the machining center are fully mechanical automation, so the production of core components has been started in Jiangcheng without anyone knowing.

Zhang Yunfeng is preparing for Dongchen to go to Jiangcheng on the third day of starting production. He first orders the crew to prepare, and then speaks to Xiaoer. “When we go to Jiangcheng this time, we have to wait until all the core parts are produced before we take them back to China shipping for assembly. Because it’s very important, we will take root in Jiangcheng before the end of this process.”

“I’m afraid it will take about ten days. There are too many parts. I’m afraid it’s still a conservative estimate for such a one-to-one processing.”

Zhang Yunfeng nodded and said, “it’s not a big problem in ten days. I’m going to Jiangcheng this time. By the way, I’ll start the production of positioning satellite. You are responsible for both, OK?”

Xiaoer said with a smile: “it’s as easy for me to do these two things at the same time as you play mobile phone while you go to the toilet…”

Zhang Yunfeng Khan gave a nod and said with a smile: “in this case, it depends on you. If you do it well, it will be a magnificent transformation for Dongchen. The national defense industry is the highest field in the industrial field. Even the aviation industry serves the national defense mostly. Now Dongchen is the absolute leader in the civil industry. If the products developed this time are sufficient If it’s strong enough, it’s equivalent to sending a signal to the world that Dongchen is about to become the only master in the field of national defense. ”

“The second one asked,” boss, even if we develop the new engine according to the design, will the military agree with us to release the engine data? ”

“It’s not a matter of whether they agree or not,” Zhang said with a smile. “It’s the fact that they will publish the final data as soon as possible.”

“Why?” “Small 2 curiously asks:” this shouldn’t be secret

Zhang Yunfeng said with a smile: “technology is confidential, but parameters are not. Now the basic data of major mainstream fighter planes in the world can be found on the network at will, and the military of all countries does not hide these data. Moreover, data is a very useful means to enhance deterrence, no need for nothing. If the military publishes these data, the surrounding countries will There will be a great sense of crisis, and some countries that like to brew small moves will probably stop a lot. ”

“If that’s the case, I think the announcement of the large skewed propeller we developed at the beginning will prove more about Dongchen’s national defense industrial capability,” he said

Zhang Yunfeng said with a smile: “this is certainly not to be published. First of all, the shape itself is a great secret. Once the shape is leaked, it may be imitated by others. At least, it points out a general development direction for others. Moreover, it is of great significance. It is not a fighter with a combat radius of only 12000 kilometers, it can Once the western countries know this secret, they will probably attract their targets when they cruise in any ocean around the world and carry a nuclear bomb capable of destroying millions of people. ”

Small two lightly nodded and said: “in this case, let the military decide.”

Zhang Yunfeng made great investment and construction in Jiangcheng at the beginning, but now it is very effective. Especially, Zhang Yunfeng established a high-precision processing center in Dongchen. With the continuous expansion of the scale, the R & D and production capacity are constantly improving. When Zhang Yunfeng arrived in Jiangcheng, this unattended production line began to flow continuously Of the finished parts, almost all the metal parts can be easily handled by this machining center, while other parts are not a big problem. The production line of Dongchen hanggong can solve most of the new parts production, and the remaining few parts can also be solved by the suppliers of Dongchen hanggong.

In the whole 12 days, Dongchen high precision machining center, Dongchen hanggong and Dongchen’s suppliers trial produced various parts of the new engine. The parts produced by the suppliers were directly sent to Dongchen hanggong, while Zhang Yunfeng took most of the core parts produced by Dongchen high precision machining center and took off from Jiangcheng to Zhonghai, ready to be on the production line Make the prototype.

In the past 12 days, Zhang Yunfeng gathered enough spare parts for three prototypes, which were handed over to the military for testing and verification.

From the day Zhang Yunfeng returned to Zhonghai, director Liu came back from Yanjing again. This time, the senior management gave Shen FA the whole thing to Zhang Yunfeng. Naturally, they also paid great attention to the new engine developed by Dongchen. From the day of assembly, director Liu became the live announcer of the whole assembly process, constantly making a brief and rapid progress to the senior management Text report for.

On the 15th day, all three engines that started to be assembled at the same time were assembled and put into production.

The design thrust is 16 tons and the afterburner is 20 tons. The weight of the afterburner used in full load is basically the same as that of the Russian engine used before the j-20. According to the fuel consumption standard given by Zhang Yunfeng, it will be at least 25% less than that of the engine of the same thrust level.

The engine officially went off the production line. Zhang Yunfeng named the engine falcon, because falcon is one of the largest raptors in physique. It is powerful and fast. It sounds more aggressive than Raptor.

“Falcon” front foot just off the line, Zhang Yunfeng back foot to find director Liu, said: “the military should not hide the international” Falcon “related performance parameters, right

“Probably not.” “This data will not be kept confidential internationally,” Liu said

Zhang Yunfeng said: “you’d better ask the senior management. If it is determined that the relevant performance parameters will not be hidden, then Dongchen will release official information to the world, informing them about the official downline of the first military aircraft engine of Dongchen.”

Director Liu asked in surprise, “no, it’s announced so early?”

Zhang Yunfeng nodded and said: “since it’s still to be announced sooner or later, it’s better to announce it earlier. Anyway, Dongchen’s products are absolutely reliable, so it’s not necessary to announce the results after all the arguments are obtained.”

“I’ll ask the superior for instructions,” said Liu. “If the superior has no opinion, it’s all up to you.”

Said, Liu can not help but ask: “Dongchen Falcon engine, probably when can achieve mass production?”

Zhang Yunfeng thought for a moment and said, “at most, half a month. After all the molds are finished, you can directly enter the mass production.”

Liu asked again, “what about the price? What’s your offer to the military? ”

Zhang Yunfeng smiled and said, “don’t worry, it’s absolutely patriotic price. It’s consistent with the current price of the Russian made al31f. It’s more than three million to four million dollars. At the same price, if the Dongchen Falcon engine is used, the military can increase the overall thrust to weight ratio under the maximum load of the j-20 to about 1.14. In most ordinary conditions, the thrust to weight ratio is more than 1.4.”

Liu Gan can’t help laughing: “your price is to force the superior to bite his teeth and upgrade all the active fighters of the whole air force!”
