Chapter 417 radar camouflage "castration"

At present, Zhang Yunfeng's stereoscopic satellite positioning system plan is basically all the external factors. The domestic government helps launch and supports itself to seek more launch resources overseas. Foreign governments are also giving more power to them. Even east haven agreed, not to mention those countries that have normal relations with Dongchen, so the rest is as soon as possible. Complete the manufacturing of the satellite and launch it.

In addition to the production of satellites, Zhang Yunfeng also has a very important task, which is to establish an unprecedented super command center in China. The traditional positioning system adopts single direction transmission and single direction reception, and there is no direct connection between the satellite terminal and the ground terminal. For example, GPS indicates the coordinates of the center of Yanjing, so it will The information of this position is transmitted to this coordinate position. After receiving the GPS signal, the terminal at this position can know its current position.

This is the same as watching TV. TV stations only send signals and TV sets only receive signals. There is no connection between the two.

However, the accuracy of Zhang Yunfeng's system is much higher than that of any existing positioning system. Because of such high accuracy, its recognition of longitude and latitude will be several decimal places after the decimal point. In addition, it is not a plane but a solid. It is equivalent to that the whole earth's three-dimensional surface will be divided into numerous nodes by the positioning system. What Dongchen has to do is not just mark these nodes Point, let the terminal to receive, but to provide a whole set of positioning services, in addition to the common civil field, other special fields, Dongchen stereo positioning system, will provide comprehensive positioning, navigation and other services for the object, which requires the whole system to have sufficient processing capacity, and is, super processing capacity.

Therefore, the ground command center must be built. As for the site selection, Zhang Yunfeng plans to be lazy and easy, so he plans to build it in Jiangcheng.

Just when Zhang Yunfeng was busy in Jiangcheng, the test of j-20 for new engine was almost finished. The military's evaluation of Falcon engine was unprecedented high, even at the expense of "the heart of the air force" which was a very high praise way to evaluate the huge changes brought by Dongchen aviation engineering to the air force.

In an interview with the media, a senior general of the air force said publicly that over the years, most of the energy of the air force of China has been looking for a really good heart. Today, the heart is finally found, and it can be called the most powerful heart in the world, without one.

At present, the main military fighters are basically equipped with Russian engines, while the j-20 and J-10 are equipped with the same engine, namely, the Russian al31f. The difference is nothing more than the j-20 dual engine and the J-10 single engine.

The design and built-up performance of the J-10 has always been very awkward. The biggest problem is that the thrust of a single engine is insufficient. Even if the Russian engine is still assembled, the thrust is insufficient, which has a comprehensive impact on the performance parameters of the whole aircraft. This kind of aircraft can still bluff people in peacetime. In wartime, it also has some advantages for small and medium-sized countries by virtue of its quantitative advantages and cooperation in other fields, But in the face of the real war, the actual combat performance of this aircraft is not optimistic. However, if equipped with the Dongchen Falcon engine, many problems of the J-10 can be solved!

The larger the battle radius, the larger the payload, and the larger the space for upgrading the avionics equipment. In this way, the J-10 can be developed into a cheap main fighter like the F-16. The strategic core of the U.S. Air Force has always been to obtain the air control right. The main fighter to obtain the air control right is not the F-22 with high cost and small quantity, but the F-16 with low cost and large quantity And the same class of shipboard aircraft.

From the moment when the military got the Falcon engine, it was not prepared to apply it only to the j-20. The j-20 is more of a deterrent role, but the importance of the J-10 cannot be replaced by the j-20. Moreover, the J-10 has already opened up the export market. The Falcon engine has a great effect on the J-10 and the overall combat effectiveness of the air force.

As soon as the test flight of the j-20 is over, the F-10 assembly Falcon engine has already flown to the sky. If the previous J-10 is an urban SUV, then it is only equipped with a 2.0 naturally aspirated engine. There is no problem in driving in the urban area, and it is basically lack of power to install five people and pull things. However, once the environment is harsh, this kind of vehicle will be eliminated There are no advantages except that the territory is higher, but once the Falcon engine is installed, it is equivalent to changing the 2.0 naturally aspirated engine into 3.0 turbocharged engine, not to say five people, even if eight people are installed, they also run very smoothly. Therefore, after the day of mounting the Falcon engine on the J-10, all the dynamic performance indexes rise in a straight line, which does not need too much verification, so the military recognizes that It was decided to replace all the J-10 engines in China with Falcon engines.

When Zhang Yunfeng was busy building satellites, the military's orders had already come down. The price of two thousand Falcon engines was 30 million yuan.

It is said that Zhang Yunfeng's original offer was only three million US dollars, equivalent to 20 million RMB, but the purchase unit price given by the government was 30 million. It seems that he was extremely satisfied with the Falcon engine, and was unwilling to take advantage of Zhang Yunfeng's profit in terms of price.

But Zhang Yunfeng can't see the profit. However, if the leaders are willing to give it, they will accept it. Director Liu will go to Jiangcheng with the contract. The contract is signed casually, but it is of great significance.

Zhang Yunfeng was very surprised at the order quantity of 2000 sets. He asked, "there are not more than 100 domestic j-20s, right? How many engines are needed for the entire J-10 and J-11 series? "

Director Liu said with a smile: "there are not many of the J-10 and J-11, but the Su 27 and Su 30mmk series add up to 340. All these old maozi produced planes can have two engines, and the original match is also the al31f engine, so it is appropriate to replace them with falcons."

With that, director Liu sighed and said: "it can be seen how miserable we are by laomaozikeng. No matter what plane we sell to us, we basically use al31f engine, and the better engine is not exported to us. We only sell al31f, so our main engine models are basically al31f engine. Now we have Falcon engine The Russian engine will gradually become history. "

Zhang Yunfeng smiled awkwardly and said: "the old hairy will cheat himself. Al31f has been sold for more than 20 years since the 1990s, so we can eat this dumb loss."

"No way." Director Liu said helplessly, "we have only one reliable way before. Western countries will certainly not sell it to us, so we can only suffer from the loss of the old maozi."

here, Liu Gan can not help but say: "yes, the radar thing, the military has not announced, this thing is too damn powerful!" It's a miracle of seconds! "

Zhang Yunfeng said with a smile: "the military is satisfied with the radar?"

"Very satisfied!" Liu Ganshi clapped his thigh and said happily: "this thing is just like the assistance of fighter God. It has increased sight distance and is completely anti stealth. How did Dongchen come up with this thing? If this thing is released, I'm afraid the whole world will be in chaos! "

Zhang Yunfeng nodded and said, "it's really going to be a mess. The concept of new radar is totally different from that of old radar. It uses the same routine as our three-dimensional positioning satellite. It has enough control over the radar wave released by itself, so any stealth aircraft has no effect on it."

"This thing is now covered very tightly by the military." "We are even worried that if this kind of radar is assembled in large quantities, the pilot will surely master the mystery. If it is leaked, it will make the western countries extremely worried. The significance of this thing is even greater than the aircraft engine. The F22, which is so expensive in the United States, is a living target in front of him!"

Zhang Yunfeng said with a smile, "don't be so greedy. This kind of thing doesn't need to be equipped with troops in an all-round way. It only needs a small amount of core strike force. At present, the best way is to equip only a small number of j-20, a small number of early warning aircraft and a small number of ground radar troops."

Director Liu nodded softly and said, "that's what the high-level officials mean. After all, the appearance of this thing is too unbalanced for the air war form of the whole world. It's totally beyond an era. If this thing is really released, I'm afraid that the whole world will try every means to target us. At that time, it won't pay off."

"Yes." Zhang Yunfeng said with a smile: "in the era of peace, we don't need comprehensive and powerful firepower. It's too powerful, but it's easy to be targeted. We just need to have enough core strike force, just like the strategic nuclear submarine. As long as we guarantee the survival ability of our strategic nuclear submarine, the whole world can't easily fight with us, because any country is afraid of it Nuclear strike. "

"Yes." Liu Ganshi smiled and said: "the radar is not ready to purchase too much for the time being, and the order will not be fully announced. In fact, the military hopes that you can use Dongchen's special technology to limit the radar's function to a certain extent, so that it can realize camouflage. For example, the same radar, in most cases, will be castrated in function, so that their performance and purpose The former normal level radar is the same. Once it's really in war, you can always make it reach its true level, which is the best. "

Zhang Yunfeng is puzzled to ask: "can the pilot adapt to this? Today's flight, tomorrow's flight, the radar will be completely upgraded. "

"Nothing." Liu said with a smile, "pilots can understand the radar. As for the size of the radar coverage, there is no problem that they are not accustomed to."

Zhang Yunfeng nodded and said with a smile, "in this case, it's not hard to achieve. Then I will give the military a special authorization code. With authorization, I can start all the functions of the radar."
