Zhang Wenhao took the initiative to carry out the research and development of military aero engines, which is definitely a great thing for Director Liu, every time he gets the instructions of the leader, he feels like he is going out to negotiate a big deal on behalf of the company, whether the contract can be signed, almost all rely on himself to negotiate with Zhang Wenhao, fortunately, Zhang Wenhao is very powerful again and again, and major things have never dropped the chain, this time it is even more joyful and grateful to Director Liu's heart. "The domain name of this site is the full spelling of the sky, please remember the domain name of this site!"

The Taihang production line is of great significance to the country, it stands to reason that almost all of this kind of institution is supported by government funding, and it has always been the core of the country's military industry, and it is also a department with a very high degree of confidentiality, however, Director Liu is not worried that Zhang Wenhao's request will be rejected by the superior leaders, because once Dongchen wants to get involved in this field, then it will inevitably come up with products that are countless times better than Taihang. Then put him in charge of producing the top aircraft engines for the military, and the deal was very cost-effective.

Immediately, Director Liu spoke: "By the way, Wen Hao, can you give me an approximate cycle?" How long does the development time take? How long does it take for a sample to actually roll off the production line and submit it to the military for testing? ”

Zhang Wenhao pondered for a moment and said: "It will take at least a few months, the most important thing is that the Taihang production line will complete the translation, and after all the translations are transferred to Zhonghai, Dongchen will also modify the old production line." ”

Officer Liu nodded and said, "This speed is already very fast!" I believe that the senior leaders will be very happy with this news. ”

Immediately, Director Liu said: "In addition to the instructions given to me by the senior leaders this time, I also asked me to convey a sentence, the iron ore matter, you have done a very good job, which is equivalent to helping the country's entire industrial system establish a strong cost guarantee, which is of great significance." ”

Zhang Wenhao smiled slightly and said, "Please also help me convey it to thank the leaders for their praise." ”

Director Liu patted Zhang Wenhao on the shoulder and said: "You are now the pillar of our domestic economy, and the senior leaders don't want to put any pressure on you, so although I really want to meet you, considering your current situation, the senior leaders are still willing to let you develop by yourself and do not interfere in your development route." ”

Zhang Wenhao nodded, what he wants is this, he will never touch politics, let alone touch the forbidden area of politics, under the framework of domestic laws and regulations, do his best to do his own thing, that is, Zhang Wenhao's greatest wish, if he adds too much political pressure to himself, I am afraid that he is willing to retire early to enjoy life.

Research and development of military engines, is not a problem for Zhang Wenhao, as long as the hardware meets the standard can be produced, Zhang Wenhao was not ready to set foot in this field too early, for fear that what he did, will bring more negative impact on the international situation, in peacetime, if because of the additional pressure brought by weapons, I am afraid it is not a good thing, but, now the most important thing is that other developed countries have begun to desperately develop more high-end products, if Dongchen does not make a move, At that time, the country's air force strength will fall behind because of the growth of others, and in this case, Dongchen will not be able to continue to sit idly by.

For Dongchen, although Dongchen Aviation is not the most profitable subsidiary, it is definitely the most significant company, although the United States Apple and South Korea's Samsung have strong earning ability, but in terms of overall influence, it is far inferior to Boeing, Pratt & Whitney, Mitsubishi Heavy Industries and other enterprises, if Dongchen Aviation begins to get involved in the design and production of military engines, Then the influence of Dongchen Aviation Engineering in the overall situation will far exceed that of other military enterprises.

However, Zhang Wenhao himself also has his own scruples, the military industry is of great significance, no matter in which country, it is inevitable to be strictly controlled by the state, if Dongchen really transforms into a military enterprise, then the senior leaders will not give Zhang Wenhao such freedom as now, when the time comes, I am afraid that he will cause a situation of cocooning and self-restraint, so conceived, Zhang Wenhao suddenly had an idea in his heart, that is, to imitate Boeing's model, Dongchen Airlines is completely divided into two ** operations, There is no relationship between the enterprises involved, one section is the current Dongchen Aviation Industry, facing the world market, the birth of civil engines, do not get involved in any political level, the other section, is after the production line of Shenfa arrived, it will be transformed into a completely closed section, this section only serves the country, all the products produced, are also handed over to the state to control, if the future of this enterprise in the eyes of the top is too significant and must strengthen supervision, when the time comes, they simply give up the entire section, There is no reluctance for Zhang Wenhao to give up, as long as it will not affect the operation of Dongchen's other normal fields, Zhang Wenhao has no opinion, and he will protect himself, which is a principle that Zhang Wenhao has set for himself before he has entered the military field in the real sense.

An enterprise, the development of multiple plates, and the division of two natures are a very practical route for the next step of Dongchen, and an enterprise is naturally to continue to start from the perspective of Dongchen Group, all subordinate industries belong to the group and serve the group, and the development of multiple plates is the sub-group that Zhang Wenhao is now constantly establishing, such as Dongchen Pharmaceutical, Dongchen Automobile, Dongchen Aerospace Engineering, and Dongchen Electronics. Although some sections were established and strengthened by themselves, they are fundamentally state-state.

If this line of thought and line is strictly implemented, it is not impossible for Dongchen to directly participate in military manufacturing in the future, and only needs to integrate all the enterprises involved in the military industry under the same nature division, and once it perceives that the wind direction has changed, it will immediately withdraw without hesitation and hand it over to the state for management.

Thinking about this principle, Zhang Wenhao suddenly had a plan in his heart that he had been brewing but did not know whether it could be realized, if he really officially set foot in the research and development and production of the military industry, maybe his plan would soon be realized.

Therefore, Zhang Wenhao looked at Officer Liu and asked, "Is the military interested in higher-end radar equipment?" ”

Director Liu, like Zhang Wenhao, lowered his head to figure out his thoughts, and suddenly heard Zhang Wenhao say such a sentence, and almost jumped up in fright.

Radar equipment?! God, how could Zhang Wenhao be so proactive and ask about such a critical area?

Modern fighters, the three most important parts, the power part, the firepower part, and the avionics part. The first two are very easy to understand, as for the avionics part, the main thing is the radar, there is a super radar, even the so-called stealth aircraft will lose its meaning, there is a super radar, the two sides can be the first to find the enemy and take the lead in attacking when they are in the air battle, this is definitely an area of great strategic significance, why has the country been sparing no effort in the development of early warning aircraft? The reason is that early warning aircraft can provide stronger radar assistance, to put it bluntly, that is, they have a stronger visual range, a broader and more detailed control of the battlefield, and all of this must be based on radar.

Director Liu asked in disbelief, "Dongchen has enough radar technology?" ”

Zhang Wenhao said: "This can be developed, based on our current strength in the field of electronics, many advantages can be transplanted, we can develop radars with stronger performance, and we can also develop fire control systems with more powerful processing capabilities. ”

Director Liu said excitedly: "If you can, of course it's a great thing!" If you have any needs, just ask, I think the top management will be willing to disclose all the parameters and technical secrets of the existing radar to Dongchen. ”

"No, you don't." Zhang Wenhao said: "Dongchen will not be developed on the basis of others, in terms of radar, it is enough for us to develop it ourselves, I just say hello to you, when the time comes, the radar will start together with the engine, I believe that there will be a significant improvement in the combat effectiveness of the domestic air force." ”

Director Liu said happily: "Wen Hao, you are simply a robot cat in Japanese cartoons!" What a want, whatever! ”

Zhang Wenhao smiled secretly in his heart, he has too much military technology to master, the engine and radar are only a small part, in addition, the rocket thruster and advanced guidance technology are all trivial for Dongchen, and even, with Dongchen's current manufacturing capacity, even if it is to build satellites and launch vehicles by himself, it is not a problem, in fact, Zhang Wenhao himself has been coveting satellites for a long time, and the plan he began to brew earlier is related to satellites.

In China, the general company wants to launch its own satellite is basically a dream, not to mention their own launch vehicle, even their own satellite is very difficult, the general civilian field, such as communications, television broadcasting and other fields of satellite demand, all need the country's strict approval procedures, basically civil enterprises are only state-owned enterprises can be eligible to apply, apply down, but also need to purchase satellites, or entrust special enterprises and institutions to design and produce, satellites have, but also spend expensive money to be launched by the national launch vehicle enterprises.

The general satellite TV also only has the financial resources to rent a band from the communication satellites that have been launched, and the country's communication companies do not have their own communication satellites, and all satellite support must rely on satellite communication groups, so to speak, renting a band is extremely cumbersome, and it is difficult to launch a satellite by yourself, and a satellite is of little significance to Zhang Wenhao.

Zhang Wenhao's thirst for satellites is not because he is committed to doing the communications industry, this industry does not need any high-end technology, for Zhang Wenhao, this industry does not have any challenges, plus the operation of this industry, most of them are state-owned giants, it is difficult for them to insert a piece of the pie, Zhang Wenhao wants the satellite, is a positioning satellite, which is of great significance to the future development of Dongchen.

In today's positioning system, there are many mainstream satellite positioning systems, GPS, GLONASS, Galileo and the domestic Beidou system, each system relies on its own satellite matrix to support, GPS has 24 satellites to support, GLONASS is also 24, and there are even more satellites as backups, the number of Beidou satellites exceeds 35.

However, in Zhang Wenhao's eyes, there are many deficiencies in any satellite positioning system in the world, first of all, the problem of signal coverage, followed by the problem of positioning accuracy, and thirdly, there is no real three-dimensional global positioning system.

The so-called real three-dimensional global positioning system, in the field of the future, is a very high-end technology, it will be the entire surface of the earth in a flat way, according to the accuracy of the square centimeter for dense segmentation, the so-called dense segmentation, that is, the entire global surface will be composed of a horizontal line with a density of less than 1 cm and a density of less than one centimeter of longitude, and the meaning of latitude and longitude is similar, but because of such a dense segmentation, each point, the distance from the adjacent point, is within one centimeter, the accuracy of positioning, That's within a centimeter.

And that's just plane cutting.

Plane cutting, there is one of the biggest problems, that is, everything is based on the surface of the earth as a basis, standing at an altitude of 1,000 meters with GPS, GPS will be based on the altitude of the ground under your feet, report the number of altitudes, but if it is at an altitude of 1,000 meters, with a hot air balloon to rise to an altitude of 2,000 meters above sea level, the positioning system will not be able to distinguish this altitude, because it can only be cut in a plane, and can not achieve three-dimensional cutting.

And Zhang Wenhao's long-coveted technology is three-dimensional cutting technology, the world's surface to the entire three-dimensional space within 30,000 meters above sea level for precise segmentation of the density of less than one centimeter, which is equivalent to the plane segmentation on the basis of every centimeter, to cut again, in the advanced view, no one believes that this technology can be realized, because in their eyes, the transmission of satellite signals is point-to-point, satellite signals can be transmitted from orbit to the ground, but the transmission process can not be cut.

If Zhang Wenhao can establish a set of advanced stereo navigation system, then it can not only be used in Dongchen Automobile, but most importantly, it can be used in the future Dongchen aircraft, if such a system is used, the aircraft can determine its most accurate position and altitude through the navigation system no matter at any position and altitude.

In this way, it can not only make the aircraft flight route more accurate, improve the efficiency of the air route, but most importantly, it can further realize the unmanned aircraft and unmanned take-off and landing throughout the whole process, and even, in the case of no visibility at all, the aircraft can also achieve accurate take-off and landing, which is much higher than the pilot's ability range.

At that time, the driver of the Dongchen car can get the navigation service with an accuracy of one centimeter, and if the aircraft is equipped with the Dongchen navigation module, it is equivalent to it can carry out incomparably accurate blind flight in any airspace below 30,000 meters above sea level in the world, only need to enter the accurate route coordinates, the aircraft will fly the entire route without any difference, no matter in the plane orientation or the upper and lower three-dimensional height, there will not be any mistakes, it can accurately find the runway and grasp the actual altitude of the runway, even if it is blocked by dense fog, The aircraft also does not need any ground guidance, every centimeter of descent, it can be accurately perceived, it can follow the prefabricated route to the middle of the runway in the dense fog, can approach the runway, to achieve a precise descent that no one can achieve, until one millimeter before touching the ground, can accurately perceive, under the support of this system, civil aviation will no longer be affected by any visibility.

If only Dongchen's aircraft are equipped with this system, then there will be an obvious polarization of civil aviation in the future, for example, the visibility of New York Airport will drop to less than 100 meters on a certain day, and under the sight of this kind of highway will inevitably be closed, whether it is Boeing's planes or Airbus planes or even those regional airliners, all of them will be suspended from and out of the port, and the flights at New York Airport will be delayed indefinitely until the visibility meets the standards before they can be released. Those planes that are preparing to go to New York will also be delayed indefinitely, and those planes that are already on the way, or are about to approach New York, will have to choose other alternate airports for alternate landing, but in this case, there is only one kind of aircraft that can take off and land completely without the influence of visual range, and that is Dongchen's plane.

All the other planes are lying in place, waiting for God to disperse the fog, a large number of passengers are stranded, but the flights of Dongchen aircraft are on duty, taking off and landing as usual, unaffected, which is definitely a huge gap for the airline, if it also wants to use this system, no problem, pay for it.

Once the positioning system forms a global coverage, its stable satellite positioning signal can support the terminal equipment infinitely, after all, the satellite does not need to provide services directly to the terminal equipment, it is only responsible for transmitting the signal, who has the terminal, who can read it, just like the satellite TV signal, who buys the pot lid, who can receive.

However, Zhang Wenhao will never make this system an open system, he will encrypt the signal, and even more on the terminal hardware, to ensure that no one can use Dongchen's positioning system without approval, and to ensure that no manufacturer can manufacture Dongchen's positioning terminal equipment.

At that time, the terminal of Dongchen positioning will be divided into two different sections of sales, one is the ground plane terminal, which can be used by vehicles and people, but will not give any actual altitude support, and all altitude data will be subject to the ground altitude. The other section is the three-dimensional terminal used in flight, which is of great significance.

Civil aviation is on the one hand, the military is also on the other, there are only two ways to measure the height of the aircraft in the world, one is that the aircraft itself uses the airspeed tube, the static pressure hole actually measures the altitude at this time, this is more accurate, the error is small, but the error within one centimeter of the distance, there is still a difference of 108,000 miles, the other is the use of ground radar test, the use of the oldest radar, through the radar reflection wave to calculate the height and speed of the aircraft, the error is incomparably large, even ten meters can not be guaranteed.

And all this, only Dongchen can. (To be continued.) If you like this work, you are welcome to recommend this work as a registered member of Piao Astronomy, your support is my biggest motivation. )
