After learning about the situation here, in fact, Wang Qiang's heart was already very satisfied. His mission here this time is very simple, just by virtue of the relationship with the Ai Zhang family, the most preliminary contact with the radar technology of the Alice Group, that is, to understand a little bit of the situation, it stands to reason that the situation has been learned here, has been able to complete his task, there is nothing for him, as long as he reports what he knows, what will happen next, no matter whether this cooperation is successful or not, it has not had much to do with him.

But this guy is not, Ya thinks, since the leader sent himself, he has to make something practical, in line with the attitude of being responsible for the work, he has to do the work comprehensively, not only to know the advantages of this radar, but also to understand the shortcomings of this radar, if you can get some confidential information from the Alice Group, it would be better.

According to the preparation you have done in advance. In addition, I consulted the comrades of the Amine Institute and the Dixi Research Institute on the technical issues of radar, and I knew about it. At present, there are still many technical difficulties in the technical perspective of phased array radar, and in the research of airborne fire control radar, not to mention active phased array fire control radar, even if it is a simple passive phased array radar, it is also a technology that they look up to for domestic radar development units.

"Mr. Feklisov, thank you for your wonderful explanation to us" Wang Qiang, this girl's badness, thinking about his little Jiujiu in his heart. After first affirming Feklisov's introduction, he then changed the subject, "But there are a few questions, we have some doubts, can you please ask Mr. Feklisov to explain our doubts?" ”

Ya's speech suddenly became crepe.

"Don't dare to be confused, General Wang, please ask." In front of his boss's good friends, especially important figures in the military, Feklisov did not dare to make a big deal at all, and hurriedly said politely. As long as it is not a technical issue that needs to be kept secret, Feklisov does not mind telling Wang Qiang, a big man in the army, at all.

If you really think that it is someone who treats yourself as a dish, then you look up to yourself too much, if it is not for your own boss, it is estimated that this guy will not look at himself, and he has been in China for so many years, and he knows very well what kind of status such a major general is in the army.

"Then you're welcome, first of all, the parts of the phased array radar antenna." Wang Qiang is not polite, there is a series of questions when he comes up, and the questions asked are all related to the core of phased array radar technology. In fact, it doesn't matter if you can't get it, with the attitude of not taking it for nothing, I asked, the piece is the core of the phased array radar antenna element, to achieve the emission and reception of radio frequency signals in a very small volume, and the components must reach a certain power and considerable sensitivity, it is very difficult to develop, can you tell me how to get your antenna part done?.

Zhang Lan, who didn't care about it, opened her mouth into an O-shape after hearing the first question asked by Wang Qiang: What does it mean to ask this question? That's not what he, a military commander, should be concerned about, right?

But Wang Qiang's problem is not over here. That's the first problem, and since there is the first, there must naturally be a second, "The second problem, in fact, is a problem closely related to the first problem, which is a little different from Doppler radar, the active phased array radar antenna is densely packed with hundreds to thousands of pieces, the thermal power is very high, the thermal power of a single component can reach several thousand watts, and if these hundreds or thousands of powers are combined, the power will reach hundreds of kilowatts, and there is such a huge thermal power distributed in such a small area. This will be a very non-empty thing. You also said in the introduction just now, the power of this active phased array radar is 3 kilowatts, so the cooling problem of this radar has become one of the keys to the success or failure of the phased array radar design.

This guy's questions are getting more and more out of tune! Seeing Wang Qiang's shameless face, I just want to probe your lowly face with loose technology. Zhang Lan was a little angry: The relationship between our two families is familiar, but you can't use the relationship between the two families to do this kind of thing, right? You're not doing this properly.

Wang Qiang didn't notice the slight unhappiness on Zhang Lan's face, or rather, he noticed it, but pretended not to know and continued to ask Feklisov. "The third question, the voltage required by the line element of the active phased array radar is not high, but the overall current required by the antenna composed of multiple array elements is very large, so it is necessary to provide a stable and pure high-power and low-voltage power supply for the array elements of these radar antennas, and it must be highly reliable and light in size and weight, how do you solve the problem of this high-power, high-density, stable and pure low-voltage power supply?"

"Finally, the question, in terms of working mode, phased array radar mainly achieves its functional advantages through flexible beam control, therefore, the requirements for data processing capabilities are much higher, how does Guiyi solve such a large amount of data processing capabilities?"

As for the answers to these questions, Feklisov did not dare to say at all, these things are all related to the key technology of the airborne active phased array fire control radar, and they are all the technologies that have been studied by those military powers for a long time, although they do not know where their boss got these technologies, but if they think that these technologies can be found casually on the street. That's a big mistake.

Ya, the questions asked are more and more scathing! Zhang Lan was indignant in her heart, even if you plan to spy on intelligence, you haven't come to spy on intelligence in such a big way, right? Asking that in front of me? It's too embarrassing for me, isn't it?

"I can answer these four questions," Zhang Lan signaled to Feklisov, who was a little at a loss, to leave this matter to himself, and asked rhetorically, "But Uncle Wang, each of these four questions involves the core technology of active phased array radar, and they are all things in the safe where they are, and it is impossible for any radar developer to reveal the claw, "Do you have such a Lei Feng for me?" Say whatever you ask, the bad thing is that you think Alice Group has no sense of secrecy about technology at all? ”,

"Huh". Wang Qiang laughed dryly, although he knew that he couldn't get answers to these questions, but he still didn't give up without asking, but just like the tightly covered baby here, that is, the shrewd ghost-like Alice Group who shouted "core competitiveness" all day long in the center, how could he tell himself the answer because of such a casual question?

But even so, Wang Qiang is already very satisfied with these gains, and the following things depend on what the above means. If the above really plans to cooperate with Alice Group, it should be reported soon.

"If you want to evaluate the performance of this radar, we welcome it at any time, whether it is the 14th Research Institute of the Ministry of Electronics Industry or the Riveting Institute. Of course, the place for evaluation can only be placed with us. Without waiting for Wang Qiang to say anything, Zhang Lan said very coawardly.

6 institutes, also known as AVIC, the first foot research institute of the group, if the numbers are more confused, of course, it can also be called riveting institute for the Chinese electronic technology research institute, is the driest component of the airborne radar research institute, but also in the airborne radar system in the most powerful research and production institutions, mainly engaged in the development and development of military and civilian electronic products, now Yangsuo has a full-level key electronic laboratory, a Sino-US cooperation period of the introduction of radar subcontracting production line; At the same time, it has strong technical strength in the field of antenna, microwave, signal and data processing, electronic circuits in various frequency bands, computer application technology, color grating display, ferrite devices, impact materials, aluminum waveguide precision casting, electronic measurement, structural technology, etc., and has strong technical strength, and its position in the domestic radar industry is a mess.

The 14th Research Institute of the Ministry of Electronics Industry is also a big mess in radar technology in China, and occupies most of the country's procurement from the corresponding domestic market in terms of ground-based radar systems, military and civilian airborne radar systems, military and civilian shipborne radar systems, satellite communication ground stations, and radio and television.

Of course, if these two radar research institutes are better, the radar used in China now does not need to be purchased from foreign countries.

"Do you know about Nasuo and the old institute? These two familiar names popped out of Zhang Lan's mouth, and this kid's familiar appearance seemed to be talking about his friend, which made Wang Qiang a little surprised in his heart.

"Please!" Zhang Lan was choked by Wang Qiang's words and rolled her eyes, "There are only two technical experts in China who study radar, and now Yangsuo and Dishan Research Institute can be expected to be our potential market competitors in the future, so we won't even know the basic situation of our competitors, right?" If that were the case, we would have failed too much. ”

Zhang Lan's words made Wang Qiang almost want to find a piece of tofu and crash to death!

Wang Qiang's report was quickly reacted. Probably the guys above didn't think that the Alice Group would be able to come up with such a radar system with excellent performance that is now in use in China, and the fire control radar is at least above the level of the year. With incredulity and disbelief, after carefully analyzing the videotape brought back by Wang Qiang, in a short period of time, the Ministry of Defense officially gave Alice Group a text. A detailed technical assessment of the airborne active phased array fire control radar developed by the Alice Group is to be carried out.

Although it is not said what to do after the evaluation, it can be known from the interest of these people above in this radar, and there is no need to ask. If they are not interested in this radar. Will it react so quickly?

As Zhang Lan expected, the people who came to formally evaluate this radar this time, in addition to the people from the Ministry of National Defense, were all people from the Riveting Institute and the Ministry of Electronics Industry, and the people from the Ministry of Defense only played a supervisory role, and basically all the work had to be handed over to the people from the Yang, the Ministry of Electronics, and the Research Institute.

And for a detailed evaluation of this radar. The Ministry of National Defense specially allocated a fund of 10,000 yuan for use during this period, after all, the person who evaluates the performance of this radar can't let the Alice Group pay for it itself, right? There is no such truth in the world.

This is very good news for Alice Group, if the radar system produced by Alice Group can really enter the domestic Air Force fighter sequence, it means that Alice Group has officially entered the ranks of the top suppliers of domestic military equipment, becoming one of the arms suppliers alongside several major military giants.

Although this situation must not be what those old men in the country are willing to see, if they are allowed to take such a good opportunity and not take advantage of it, it is obviously not their style

Now is not the era of seclusion and seclusion at the end of the Qing Dynasty. It's not someone else's stuff no matter how good it is, and it's not the time to use it.

Zhang Lan didn't think about holding this technology in his arms completely, out of the idea of stimulating domestic military technology, if necessary. Cooperation between the two sides is not something that cannot be considered, although the way of cooperation is still to be discussed, but as long as these guys are not too greedy, Zhang Lan does not care very much: there are many good things in his stomach.

But there are problems with these technical assessments. For Zhang Lan, there is no big deal, these things are not problems that can be solved in a day or two, even if it is just a preliminary technical assessment. Without a month's time to get it done, Zhang Lan naturally couldn't stay here all day. Zhang Lan, who felt that she should take a vacation and should have no problems for the time being, seemed to finally remember that she was still a student at the moment, and the current situation is. His senior year of high school is about to start in ten days, Zhang Lan looked at the sun in the sky that can heat people to death, and couldn't help but sigh, "This *** day is really fast!" ”。
