Chapter 415 launch resources

After a series of tests in the later stage, a single phased array antenna began to be mass produced. According to the different needs of different planes and ground radars, Xiaoer changed his phased array radar into three different models. The new phased array radar is named "eagle eye", the aircraft model of fighter is eagle eye 1, the aircraft model of large aircraft and early warning aircraft is eagle eye 2. The ground model is Hawkeye 3.

The biggest difference among the three different eagle eye radars is the difference in volume. For a single combat unit like fighter, the radar detection distance of three to five hundred kilometers is enough for actual combat. After all, its own combat ability can't even exceed this distance. Moreover, the larger the distance is, the larger the airspace the radar needs to scan. In this way, the radar first needs to More phased array antennas and more power are needed to meet the needs of further distance detection. In this way, the larger the detection distance, the greater the weight and volume, and the greater the power required. For fighters, every kilogram in the lift off weight is very valuable. Therefore, high-power radars are not suitable for fighters.

The effective detection distance of eagle eye 2 is within 7001000 km, and the increase of detection range makes the weight of the whole set of radar increase geometrically. However, for the early warning aircraft, a large-scale aircraft mainly serving radar services, this weight is nothing to it. Because of its larger coverage area, the demand for processing capacity of eagle eye 2 also increases greatly, so that Yu Xiaoer specially built a processing platform for it, using Dongchen's own CPU.

The effective detection distance of eagle eye 3 is even several times larger than that of eagle eye 2. Its core task is to scan the largest range as much as possible and track more targets as much as possible. This kind of radar, which is already a base station type early warning radar, has a strong control over the whole airspace, and as an early warning information source, it can serve non target Often more, it can not only indicate the target with longer distance for the air fighter, but also combine with the fire control system to provide the radar service for the surface to air missile directly.

For Zhang Yunfeng, the main purpose of the new phased array radar is to exchange for tickets for satellite launch. After he handed over three radars to the military for testing, Zhang Yunfeng discussed with his sophomore about the research and development of three-dimensional positioning satellites. For more than 30 satellites, Zhang Yunfeng hopes to launch all of them within one year, even for some time in one year It's too long.

Xiao Erxin knows that Zhang Yunfeng can't wait for the three-dimensional satellite positioning system, so he said to Zhang Yunfeng at the moment of research and development: "boss, I think you can now negotiate with those countries that have the ability to launch satellites, and let them provide us with commercial launch services. If you can use all the launch vehicles and launch centers in the world, then Then I think in two months at most, our three-dimensional navigation system can be completed. "

Zhang Yunfeng said: "I consulted with the senior management about the overseas commissioned launch before, and the senior management did not raise any objection, but they still hope to complete the launch at home as much as possible."

"It's too long." Small two can't help but say: "if all depends on domestic launch, it will take at least two or three years to launch all the satellites we need. Even now that Dongchen has funded to build a new launch base together with the state, we still have to follow the domestic launch capacity without launch vehicle technology. It's impossible to spare ten satellites a year."

Zhang Yunfeng nodded and said: "this can be communicated with the United States, e country and those countries in Europe. In view of our current situation, I believe these countries will not refuse."

"Don't forget Dong'ou, their satellite launch technology is world-class, but we can communicate with Dong'ou government to let Dong'ou undertake certain launch tasks," the waiter reminded

Zhang Yunfeng thought for a moment and said, "look at the density of satellite launches in various countries at present, as well as their maximum launch capacity. Estimate the remaining launch capacity. How much is the total monthly launch capacity?"

Thirty satellites can be launched in a month and a half. "

"There are some risks in satellite launching, so I estimate that we need to launch the most conservative satellite 35 times to ensure that our entire positioning system can cover the whole world. Of course, there are also risks brought by launch errors."

Zhang Yunfeng thought for a moment and said, "how long will it take to build 35 satellites?"

The waiter replied: "soon, we can make use of our own technology for the main body of satellite production and battery. As for solar cell, we don't need to develop it ourselves. We can purchase it directly from the supplier."

Zhang asked again, "how many years is the life span of each satellite?"

"More than 50 years." Xiaoer replied: "our technology is absolutely the top in the world. As long as the launch vehicle can put the satellite into the predetermined orbit, there will be no problem with the satellite for at least 50 years. If you are not sure, you can also launch several more satellites as a backup."

"At least 40 satellites should be prepared for the spare and possible launch errors, which will be completed by you. As for the launch carrier, I'll meet with Liu Ganshi again and let him tell the high-level that Dongchen can't wait too long. Once the satellite is completed, we will find the most launch vehicle resources in the shortest time for us to complete the launch quickly Shoot. "

"Don't worry, boss. Forty satellites are nothing more than that. It won't take more than two months. You'd better determine the launch resources of forty satellites within two months. Then the satellites can directly enter the launch process."

Zhang Yunfeng shook his head and said, "I will start to do this after meeting with Director Liu, and I can't wait for you to build all 40 satellites before launching them. Instead, I will seize the time to implement the launch resources. Then whenever you have a satellite offline, we will send it to the orbit at the first time!"

officer Liu has been very busy recently. After the military got the "Falcon" engine from Zhang Yunfeng, the whole senior management attached great importance to the frequent flight test, and he became a forward special agent. Most of the time, he was on the flight test site, and communicated more first-hand information about the flight test to the senior leaders, and played a certain role in the whole flight test Regulating effect.

However, the Falcon engine hasn't really completed the test of multiple models. Zhang Yunfeng's eagle eye radar has been delivered to the military for test. This time, the military is even busier. A large group of radar and electronic equipment experts rush into the test field of j-20 to remove the radar of the test plane and replace it with the eagle eye radar of Dongchen. The significance of this test is no less than that of the engine If this set of radar really meets the standards Zhang Yunfeng said, even if it is installed on the J10, it can also bring a significant improvement to the actual combat capability of the aircraft.

Hearing the news that Zhang Yunfeng is going to meet with him, Liu Ganshi rushes to Jiangcheng. Before he comes, the senior management has explained to him. This time, the meeting with Zhang Yunfeng should be within 48 hours as early as possible. 48 hours later, director Liu will go back to the test airport to track the test of j-20 equipped with new engine and new radar.

When they came to Jiangcheng, the people of the motor train received director Liu to Dongchen's office headquarters in Jiangcheng. After meeting with Director Liu and Zhang Yunfeng, they exchanged greetings. Director Liu then said, "Yunfeng, it's a very special time. The senior management attaches great importance to the two sets of military tests. I don't even have a pee time every day. This time you call me here, the senior management only I've been given 48 hours. Within 48 hours, I have to go back to the scene, so we two don't need to be more polite. You can just say what you have. When you're done recently, I'll talk to you about the past. "

Zhang Yunfeng said with a smile, "well, since you said that, I won't go around in circles." Said, Zhang Yunfeng said: "I'm looking for my elder brother to come here. I hope you can help me convey a situation to the senior management."

"What's the matter?" Director Liu asked.

Zhang Yunfeng said: "now we have started to manufacture the three-dimensional navigation satellite, but the launch capacity in China is really limited. Dongchen can't wait two or three years for the launch. So, I want to use the cooperation between Dongchen and other countries to entrust countries with the ability to provide commercial launch services for Dongchen. If the senior management doesn't object, I will Now it's time to do it. "

Liu Ganshi thought about it and said: "the senior management is not against it, but has certain scruples and worries about your technology being contacted by foreign countries. However, as far as the strength of Dongchen is concerned, no one has the ability to copy, so I don't think the senior management will have any opinions."

Zhang Yunfeng said with a smile: "you'd better confirm with the senior management. If you do, I'll start to push forward this matter immediately, and try to get all the launch needs done before our first satellite goes offline. In this way, as long as a satellite is built, it can be sent to all parts of the world for launch at any time."

Liu thought for a moment, and then said, "well, now I'll contact Yanjing to convey your ideas to Yanjing."

Zhang Yunfeng nodded and said, "the sooner the better."

Director Liu said with a smile, "you still can't believe me? When can I drag you back? "

Although the information has been delivered to Yanjing, it needs to be discussed through internal meetings after the top level reports it. So Zhang Yunfeng waited for 24 hours. After 24 hours, Liu Ganshi's mobile phone received an email, the content of which is very simple: "Dongchen is in charge of all matters related to satellite launch."

Zhang Yunfeng was relieved. The senior management gave him full control, which means that no matter what you do, you can do whatever you want.

With this permission, Zhang Yunfeng immediately, in the name of Dongchen, contacted the United States, e-country, Ukraine, ESA, donggood, India, Australia and other countries, and made Dongchen's request that they assist in the commercial launch
