The single phased array antenna went into mass production after a series of tests in the later period. Xiaoer also evolved the phased array radar he developed into three different models according to the different needs of different aircraft and ground radars.
The new phased array radar is codenamed "Hawkeye". The airborne model for fighter jets is Hawkeye-1, the airborne model for large aircraft and early warning aircraft is Hawkeye-2, and the ground model is Hawkeye-3.
The biggest difference between the three different Hawkeye radars is the size. For a single combat unit such as a fighter jet, the radar detection range of three to five hundred kilometers is enough for actual combat use. After all, its strike capability even exceeds
However, this distance, and the greater the distance, the larger the airspace that the radar needs to scan. In this case, the radar first needs more phased array antennas and greater power to meet longer-distance detection. In this way,
The greater the detection range, the greater its weight and volume, and the greater the power required. For fighter jets, every kilogram of lift-off weight is very precious, so high-power radar is not suitable for fighter jets.
use.
The effective detection range of Hawkeye-2 is within the range of 700-1000 kilometers. The increase in detection range will increase the weight of the entire radar exponentially. However, for large aircraft such as early warning aircraft, which mainly provide radar services, this is
Weight is nothing to it, and because of its larger coverage area, the Hawkeye-2 has greatly increased its demand for processing power, so that Xiaoer specially built a processing platform for it, using all
Dongchen’s own CPU.
The effective detection range of Hawkeye-3 is even several times greater than that of Hawkeye-2. Its core mission is to scan the largest range as much as possible and track as many targets as possible. This kind of radar
, already a base station type early warning radar, has strong control over the entire airspace, and as a source of early warning information, it can serve many objects. It can not only indicate longer-distance targets for air fighters, but also communicate with
Combined with the fire control system, it directly provides radar services for surface-to-air missiles.
For Zhang Wenhao, the main purpose of the new phased array radar is to exchange for tickets for satellite launches. After he handed over the three radars to the military for testing, Zhang Wenhao discussed the development of stereopositioning satellites with the waiter.
At work, Zhang Wenhao hopes to launch more than thirty satellites within one year. Even one year is a bit too long.
The waiter knew that Zhang Wenhao couldn't wait for the three-dimensional satellite positioning system, so when he was developing it, he said to Zhang Wenhao: "Boss, I think you can now negotiate with those countries that have satellite launch capabilities and let them do it for us."
To provide commercial launch services, if all launch vehicles and launch centers around the world can be used, then I think our three-dimensional navigation system can be completed in two months at most."
Zhang Wenhao said: "I have consulted with the senior management before about commissioning overseas launches, and the senior management did not raise any objections, but they still hope to complete the launch locally as much as possible."
"This is too long." The waiter couldn't help but said: "If we rely entirely on domestic launches, it will take at least two or three years to launch all the satellites we need. Even now, Dongchen has invested in and jointly established a new launch facility with the country.
At the base, we don’t have launch vehicle technology, so we still have to follow domestic launch capabilities. Even ten satellites a year would be great.”
Zhang Wenhao nodded and said: "We can communicate this with the United States, Russia and European countries. Judging from our current situation, I believe these countries will not refuse."
The waiter reminded: "Don't forget that there is Japan. Their satellite launch technology is also world-class. We can communicate with the Japanese government and let Japan also undertake certain launch tasks."
Zhang Wenhao thought for a while and said: "Look at the current density of satellite launches in various countries, as well as their maximum launch capabilities, and estimate how much of the remaining launch capabilities are available per month?"
The waiter immediately searched for relevant information on the Internet, including information visible to everyone on the Internet, as well as confidential information from various countries. The final conclusion he came to was: "Boss, the current satellite launch market around the world is very flat. There will be no satellite launch market this year."
Regarding large-scale launch missions and plans, I think if we can bring all these countries together, thirty satellites can be launched in one and a half months."
With that said, the waiter added: "Satellite launches also have certain risks, so I estimate that we will need to launch 35 times at the most conservative estimate to ensure that our entire positioning system can cover the world. Of course, there are also launch errors that will cause us
risks.”
Zhang Wenhao thought for a moment and said: "How long will it take to build 35 satellites?"
The waiter replied: "Soon, we will produce the main body of the satellite ourselves, and we can also use our own technology to store the batteries. As for the solar cells, we don't need to develop them ourselves, we can just purchase them directly from the suppliers."
Zhang Wenhao asked again: "How many years is the lifespan of each satellite?"
"More than fifty years." The waiter replied: "Our technology is absolutely top-notch in the world. As long as the launch vehicle can send the satellite into the predetermined orbit, there will be no problems with the satellite for at least fifty years. If you
If you are really worried, you can launch a few more satellites as backup."
"Including spares and possible launch errors, at least forty satellites must be prepared. I will leave these to you. As for the launch carrier, I will meet with Director Liu again and ask him to inform the senior management.
Dongchen cannot wait too long. Once the satellite is manufactured, we will find the most launch vehicle resources in the shortest time to complete the launch quickly for us."
The waiter blurted out: "Don't worry, boss, it's just forty satellites. It's not a problem, and it won't exceed a two-month cycle. You'd better determine the launch resources for forty satellites within two months. By then,
, the satellite can directly enter the launch process."
Zhang Wenhao shook his head and said: "I started working on this matter after I met Director Liu, and I can't wait until you build all forty satellites before launching them, but seize the time to implement the launch resources."
, and then whenever you have a satellite offline, we will send it to orbit as soon as possible!”
Officer Liu has been very busy recently. After the military got the "Falcon" engine from Zhang Wenhao, the frequent test flights attracted the attention of the entire senior management. He became a frontline correspondent and spent most of his time at the test flight site.
Convey more first-hand information about the test flight to senior leaders and play a certain coordination role in the entire test flight.
The "Falcon" engine has not yet completed the testing of multiple aircraft models. Zhang Wenhao's Hawkeye radar has been delivered to the military for testing. This time, the military is even busier. A large number of radar and electronic equipment experts have poured in.
At the J-20 test flight site, the radar of the test aircraft was removed and replaced with Dongchen's Hawkeye radar. The significance of this test is no less than that of the engine. If this set of radars really meets the standards mentioned by Zhang Wenhao, then this set of radars
Even if the radar is installed on the J-10, it can bring a considerable improvement to the aircraft's actual combat capabilities.
After hearing the news that Zhang Wenhao was going to meet with him, Director Liu hurried to Jiangcheng. Before coming, the senior management told him that this meeting with Zhang Wenhao should be done within 48 hours as early as possible. After 48 hours, Director Liu would have to rush back again.
Return to the test airport and follow the entire test of the new engine and radar installed on the J-20.
When they arrived in Jiangcheng, the people on the train took Director Liu to Dongchen's office headquarters in Jiangcheng. When Director Liu met with Zhang Wenhao, the two exchanged a few words, and Director Liu said: "Wen Hao, these are extraordinary times.
The military attaches great importance to both sets of tests. Normally, I don’t even have time to pee every day. This time you called me over, and the top management only gave me 48 hours. Within 48 hours, I had to
Back to the scene, so there is no need for the two of us to be more polite. If you have anything to do, just say it. When I am done with my recent work, I will catch up with you, brother."
Zhang Wenhao smiled and said: "Well, since you have said so, brother, then I won't talk in circles." After saying that, Zhang Wenhao said: "I came here to ask you, mainly because I hope you can help me convey it to the senior management.
A situation.”
"What's going on?" Officer Liu asked.
Zhang Wenhao said: "We have now started the manufacturing of three-dimensional navigation satellites. However, the domestic launch capacity is indeed limited. Dongchen cannot wait in line for launch in two or three years. Therefore, I want to use the cooperation between Dongchen and international countries.
We have established a cooperative relationship and entrusted capable countries around the world to provide commercial launch services for Dongchen. If the top management does not object, I will start doing it now."
Director Liu thought for a while and said: "The senior management is not opposed to this matter, but they have certain scruples and are worried that your technology will be exposed to foreign countries. However, judging from Dongchen's current strength, no one has the ability to make copies.
, so I don’t think the senior management will have any objections.”
Zhang Wenhao smiled and said: "You'd better confirm with the senior management. If confirmed, I will immediately start to promote this matter and strive to get all the launch requirements completed before our first satellite goes offline. In this case
, as long as a satellite is built, it can be sent to various parts of the world for launch at any time.”
Officer Liu thought for a moment and then said: "Well, let me contact Yanjing now and convey your thoughts to Yanjing."
Zhang Wenhao nodded and said: "The sooner the better."
Officer Liu smiled and said, "You still can't trust me? When have I ever dragged you back?"
Although the information has been conveyed to Yanjing, it was reported layer by layer. After the senior management learned about it, it still needed to be discussed through internal meetings. Therefore, Zhang Wenhao waited for a full 24 hours. After 24 hours, Director Liu's characteristic mobile phone received
An email arrived. The content of the email was very simple: "Dongchen has the final say on all matters related to satellite launch."
At this time, Zhang Wenhao breathed a sigh of relief. The senior management gave him full power to make the decision, which meant that they didn't care about you, and you could do whatever you wanted.
After receiving this permission, Zhang Wenhao immediately contacted the United States, Russia, Ukraine, ESA, Japan, India, Australia and other countries in the name of Dongchen, and made a request that Dongchen hoped that they would assist in commercial launches. Commercial launches
The launch process is not complicated. As long as these countries determine that the satellites being launched are for commercial purposes rather than military purposes, they will generally not refuse.
When making launch requests to these countries, Zhang Wenhao very directly stated the purpose of Dongchen's satellite launch - positioning satellite.
This has greatly puzzled those countries that have the ability to launch artificial satellites. China has already built most of its Beidou navigation system. In a few years, perhaps the global navigation system will be completed, and the technical level of Beidou navigation itself is among the top in the world.
, after all, the GPS in the United States is many years earlier than Beidou, and the upgrade of satellites is very difficult. Once the structure of Beidou global navigation is completed, its comprehensive strength will be greater than that of GPS. Therefore, in this case, Dongchen actually
It seems a bit unnecessary to develop your own positioning system.
After all, no country has built two satellite navigation systems on its own. Not only is there a huge waste of resources, but the satellite launch and navigation system architecture themselves are also extremely costly projects. In their eyes, Dongchen has no need to do this.
However, Dongchen insisted on building his own satellite navigation system, and changed his previous wording, no longer asking for assistance in launching, but asking for assistance in launching. This time, it can be seen that Dongchen’s attitude towards this matter
No matter how strong the insistence is, these countries are not prepared to go against Dongchen. Anyway, commercial launch itself is not a violation of principles. Since Dongchen wants to launch and has sufficient financial support, these countries do not have any
The need to refuse.
Dongchen has a strong influence all over the world. When it announced that it would build its own satellite navigation system, the whole world was surprised, but there was not much discussion. After all, Dongchen was too powerful. They
They have enough financial resources to build their own satellite navigation system, and they have no idea how the navigation satellite Zhang Wenhao will launch this time is different from previous navigation satellites.
The United States replied that it could arrange the launch of eight satellites for Dongchen in a short period of time. The European Space Agency was also very helpful. It also provided the launch capacity of eight satellites to Dongchen. Russia gave five, Ukraine gave two, and Japan
Five were given, and India also gave five.
After calculation, the overseas launch quota alone has reached 35, which can fully meet Zhang Wenhao's launch needs. Even if there is a certain probability of failure, normally, for the launch of thirty-five satellites, the maximum number of failures is
It is impossible to reach five, not to mention that China can still provide at least five to eight satellite launch capabilities. In this way, all launch needs have been solved. (To be continued. If you like this work, you are welcome to come
