Zhang Wenhao's stereoscopic satellite positioning system plan has basically been properly adjusted at present, the domestic government helps launch and supports itself to seek more launch resources overseas, and foreign governments are more powerful, even Japan has agreed, not to mention those countries with normal relations with Dongchen, so that the remaining thing is to complete the manufacturing of the satellite as soon as possible, and then launch.

In addition to the production of satellites, Zhang Wenhao also has an extremely important task, that is, to establish an unprecedented super command center in the domestic site, the traditional positioning system, the use of one-way transmission, one-way reception, there is no direct connection between the satellite terminal and the ground terminal, for example, GPS indicates the coordinates of a certain place in the center of Yanjing, then it will transmit the information of the location to this coordinate location, where the terminal at this location, after receiving the GPS signal, You will be able to know where you are at the moment.

It's the same as watching TV, where the TV station only sends the signal and the TV only receives the signal, and there is no connection between the two.

However, Zhang Wenhao's system, the accuracy is much higher than any existing positioning system, because of such a high accuracy, its recognition of latitude and longitude will be several decimal places, plus it is not a plane but a three-dimensional, equivalent to the three-dimensional surface of the entire earth will be divided into countless nodes by the positioning system, what Dongchen has to do is not just mark these nodes, let the terminal to receive, but to provide a complete set of positioning services, in addition to the ordinary civilian field, other special fields, Dongchen stereo positioning system, It will provide comprehensive positioning, navigation and other services for objects. This requires sufficient processing power for the entire system. And it is. Superior processing power.

Therefore, the ground command center must be built, and as for the site selection, Zhang Wenhao is also lazy and trouble-free, so he is ready to establish it in Jiangcheng.

Just when Zhang Wenhao was busy working in Jiangcheng, the test of the J-20 for the new engine was basically coming to an end, and the military's evaluation of the Falcon engine was unprecedentedly high, and even did not hesitate to use the extremely high praise of "the heart of the Air Force" to evaluate the great changes brought by Dongchen Aviation to the Air Force.

A senior general of the Air Force was interviewed by the media. It has been publicly stated that for so many years, the Chinese Air Force has spent most of its energy looking for a really good heart, and today, this heart has finally been found, and it can be called the most powerful heart in the world, there is no one.

The military's current main fighters are basically equipped with Russian-made engines, and the J-20 and J-10 are equipped with the same engine, that is, the Russian-made AL-31F, the difference is nothing more than the J-20 twin engine and the J-10 single engine.

The design and performance of the J-10 has always been very embarrassing. The biggest problem is the lack of thrust for a single engine, even with a Russian-made engine. Insufficient thrust, it comprehensively affects the performance parameters of the whole aircraft, this kind of aircraft bluffing in peacetime is OK, wartime with the advantage of numbers and cooperation in other fields, there are also certain advantages over small and medium-sized countries, but in the face of the real war, the actual combat performance of this aircraft is still not optimistic, but if it is equipped with the Dongchen Falcon engine, many problems of the J-10 can be solved!

The combat radius is larger, the bomb load is larger, and the avionics equipment has more room for upgrading, so that the J-10 can be developed into a cheap main fighter like the F16, and the strategic core of the US Air Force has always been to obtain air supremacy, and its main fighter to obtain air supremacy is not the expensive and scarce F-22, but the low-cost, numerous F-16 and carrier-based aircraft of the same class.

From the moment the military got the Falcon engine, it was not ready to apply it only to the J-20, the J-20 is more of a deterrent, but the importance of the J-10 is irreplaceable by the J-20, and the J-10 has already opened the export market, and the Falcon engine has a great effect on the J-10 and the overall combat effectiveness of the Air Force.

As soon as the J-20 flight test ended, the J-10 was equipped with a falcon engine and flew into the sky. Then he is equipped with only a 2.0 naturally aspirated engine, the city is not a big problem, five people and then pull something is basically lack of power, but once the environment is harsh, this kind of car in addition to the higher terrain, nothing else has any advantages, but once the falcon engine is installed, it is equivalent to the 2.0 naturally aspirated engine, replaced with 3.0 turbocharging, not to say that five people, even if eight people, it is also very slippery, so, after the J-10 is equipped with the falcon engine, the power performance indicators have risen sharply, and there is no need for too much verification, the military has determined that all the domestic J-10 will be replaced with falcon engines.

When Zhang Wenhao was busy building satellites, the military's order had already come down, 2,000 Falcon engines, and the unit price was 30 million yuan.

It is said that Zhang Wenhao's original quotation was only 3 million US dollars, which is equivalent to 20 million yuan, but the purchase unit price given by the government was 30 million, and it seems that he is also extremely satisfied with the Falcon engine, and is unwilling to card Zhang Wenhao's profits in the price.

But Zhang Wenhao didn't look down on this profit, but the bosses were willing to give, so he would accept it with peace of mind, Director Liu went to Jiangcheng with the contract, and the contract was signed very casually, but the significance was extremely significant.

Zhang Wenhao was very surprised by the number of 2,000 units, and he asked: "There are not more than 100 domestic J-20s, right?" How many are the full series of J-10 and J-11, and can they use so many engines? ”

Director Liu said with a smile: "J-10 and J-11 are indeed not very many, but the su-27 and su-30MMK series, adding up to three or four hundred, these old Maozi aircraft are all twin-engine, and the original configuration is also AL-31F engine, which is suitable to replace with a falcon." ”

Speaking, Director Liu couldn't help sighing, and said: "This shows how miserable we are by Lao Maozi, no matter what aircraft are sold to us, they basically use AL-31F engines, and better engines are not exported to us, only AL-31F are sold, so that our main models are basically all using AL-31F engines, and now we have Falcon engines, and Russian-made engines will slowly become history." ”

Zhang Wenhao smiled awkwardly and said: "Lao Maozi himself is good at fooling, AL-31F has been sold from the 90s to the present, and it has been sold for more than 20 years, so we can suffer this dumb loss." ”

"I can't help it." Director Liu said helplessly: "We only had this reliable way before, and Western countries will definitely not sell it to us, so we can only suffer the loss of Lao Maozi." ”

Speaking of this, Director Liu couldn't help but speak: "By the way, the military has not announced the radar matter, this thing is too powerful!" It's a god that kills in seconds! ”

Zhang Wenhao smiled: "The military is satisfied with the radar? ”

"I'm so satisfied!" Director Liu slapped his thigh and said happily: "This thing is simply a combat god-like auxiliary, with increased sight distance and complete anti-invisibility, how did Dongchen come up with this thing?" If this thing is announced, I'm afraid the whole world will be in chaos! ”

Zhang Wenhao nodded and said: "It's really going to be a big mess, the concept of the new radar is completely different from the old radar, it uses the same routine as our stereostatic satellite, and has enough control over the radar waves released by itself, so any stealth aircraft has no effect on it." ”

"This thing is very tightly covered by the military now." Director Liu said: "We are even worried that if this kind of radar is assembled in large quantities, then the pilots will inevitably grasp the secrets, and if it leaks out, I am afraid it will make Western countries extremely worried, the significance of this thing is even much greater than that of aircraft engines, and the F-22, which is so expensive in the United States, is simply a live target in front of him!" ”

Zhang Wenhao said with a smile: "Don't be so greedy, this kind of thing is not necessary to fully assemble troops, only a small amount as the core strike force is enough, the best way at present is to only assemble a small number of J-20, a small number of early warning aircraft and a small number of ground radar troops." ”

Director Liu nodded lightly and said: "This is also the meaning of the high-level, after all, the appearance of this thing is too unbalanced for the form of air warfare in the whole world, it is simply beyond an era, if this thing is really announced, I am afraid that the whole world will try all means to target us, and at that time, the gains will outweigh the losses." ”

"yes." Zhang Wenhao said with a smile: "In peacetime, there is no need for comprehensive and powerful firepower, it is too powerful, but it is easy to become the target of public criticism, just need to have enough core strike force, just like strategic nuclear submarines, as long as we ensure the survivability of our strategic nuclear submarines, then the whole world does not dare to easily start a war with us, because any country is afraid of nuclear strikes." ”

"Yes." Officer Liu smiled and said: "The radar matter, for the time being, I am not going to purchase too much, and the order will not be fully announced, in fact, the military hopes that you can use Dongchen's special technology to impose certain functional restrictions on the radar, so that it can achieve camouflage, for example, the same radar, in the vast majority of the time, will be castrated functionally, so that their performance is no different from the current normal level of radar, once it really comes to wartime, you can let it reach its true level at any time, this is the best." ”

Zhang Wenhao asked puzzledly: "Can the pilot adapt to this?" If you fly today, you will drive it tomorrow, and the radar will be completely upgraded. ”

"It's fine." Director Liu said with a smile: "Pilots can understand the radar, and as for whether the area covered by the radar is large or small, there is no problem for them to be unaccustomed." ”

Zhang Wenhao nodded and said with a smile: "In this case, it is not difficult to achieve, and when the time comes, I will give the military a special authorization code, and with authorization, you will be able to activate the full function of the radar." (To be continued.) )
