Chapter 98: Great God Meeting

The man who rushed in was not tall, had a face with Chinese characters, was in his early forties, had a square face, and his sparse hair was combed twenty-eight.
Tan Zhenhua took a closer look. This acquaintance is not only acquainted, but also very familiar. He called this uncle when he was a child. He has been called this uncle for more than ten years, but he is a neighbor in the gray building No. 9 who lives on the second floor. Ben put Ben the great god.
But what kind of virtue is this person, who should be named a great by Xiao Tan Tan?
Of course it's because this one will be too great in the future.
Ben Fang, born in 1938, Manchu, graduated from Harbin Institute of Technology in 1963 with a major in Radar. He is Tan Ming's alumnus, but his achievements are far worse.
In the history of Tan Zhenhua’s previous life, he was one of the founders and academic leaders of China’s airborne fire control radar. He has won many national and ministries awards and participated in the development of the first phased array radar "7010" in China. .
But these are trivial matters.
What really established his position in the field of China's radar engineering research was that in 1989, as the chief division, he successfully developed China's first pulse Doppler airborne fire control radar.
Because of his special contribution to the country, Ben Fang was elected as an academician of the China Academy of Engineering in 2001, that is, the academician who came out of Building 9 mentioned above.
However, these are all things to do. The current Master Ben Fangben does not have a trace of the demeanor of a future academician, but like a street splash, Jen Nuozhu keeps jumping.
While pulling him out, Zhan Nuozhu rolled his eyes and said, "Hey, hey, this is new clothes. Don't tear it up! A gadget flew up here. You can't see it. It's your radar. How can you ask me the question! Besides, you have to ask the person who made this gadget, what are you doing with me?"
Ben Fang found out that there were three more standing on one side. When he saw it, he still knew each other.
Tan Zhenhua didn't say anything, he grew up when he was a kid. The other two were related to a pre-research project he received last year. For that subject, he had also had several dealings with these two aviation giants, and they were quite familiar.
Seeing these few people, he hurriedly stepped forward to say hello: "Professor Song, Professor Guo, and Zhenhua, why are you all here? Could it be that you made the gadget that just flew?"
To say that the brains of the future academicians are good, and you can see the key people at a glance, just the big boss of Zhan Nuozhu, what good things can be made?
Song Wenhua said with a smile: "Ben Gong, that's what happened. A few months ago, Zhenhua made a four-rotor drone. Both Lao Guo and I found it interesting. We optimized it and planned to fly today. Look at the effect. I heard that you have a dual-coordinate radar for factory testing today. It happened to be used to see the effect, so I set the test flight location here. Here, it’s what Lao Guo holds. How is it, beautiful? Right? I just heard Xiao Zhan say, can't see?"
Ben Fang replied dejectedly: "It will be filtered out after a flash. It is really invisible. In the future, this will be a trouble."
Tan Zhenhua nodded secretly in his heart, the future academician, the foresight of new technology products really leveraged, he knew at a glance, this thing will be a trouble in the future.
is not it? This thing is too small, flying low and slowly, ordinary radar can't use it at all. Moreover, even if it is seen by radar, how to get it down is still a problem.
For this reason, when this gadget became popular after entering the 21st century, countries have invested heavily in research on how to "discover-dispose" such "low and small" targets, and a specialized discipline has been derived. As for the methods used, it is even more strange-
For example, special radars for detecting "low, small, slow" targets, such as electromagnetic interference guns, electronic fences and even laser guns, etc., and the most incredible thing is the fishing net!
Unfortunately, the results are not very satisfactory.
Therefore, various key areas are invaded by drones from time to time, such as airports, key government departments, confidential facilities, and so on. The most bizarre thing is that the British Empire has held back the aircraft carrier "Queen Elizabeth" for several years. As a result, the F-35 carrier-based aircraft provided by the good Eagle sauce did not have time to deliver. When the first sea trial was pulled out with an empty deck, a UAV made by China landed on the aircraft carrier in a big swing. Became the first aircraft to land on this ship.
Song and Guo don't care about this, they look at each other and smile, you can't see it, you can't see it!
Tan Zhenhua couldn't do it. He was a junior, so he respectfully stepped forward and said: "Hello Uncle Ben."
Ben Fang looked at Tan Zhenhua's face and asked Xingshi: "You made this thing?"
Tan Zhenhua hurriedly tossed the pot: "No, no, I made a prototype. The flying one is made by Professor Song and Professor Guo."
Ben Fang turned to Song and Guo again, "It's still with you two, you are not allowed to go today, let's find a place, you can explain this gadget to me!"
Tan Zhenhua was happy to hear this, okay, this is the meeting of the three great gods.
The place was ready, and a few people sat down in an empty cabin next to the test site.
Ben Fang pointed to the drone in Professor Guo's hand and said, "Old Guo, please tell me about this first."
Professor Guo said: "My mouth is dumb, Old Song can speak, he should come."
Song Wenhua didn't refuse, pointing to the drone and said: "Well, then I will talk about it."
"Let’s start with the motor. This motor uses silicon steel sheet magnets imported from Japan, single-strand winding, brushless motors, high-precision bearings, matching drivers, and 124.5 carbon fiber blades. A 40% increase in power over the prototype and a 100% increase in pulling force have greatly improved the load capacity of the body."
After showing off these things, he cast a sideways glance at Tan Zhenhua.
Tan Zhenhua immediately blushed, and he cursed in his heart: Nima, you are professional, okay, compared with my amateur, are you embarrassed? As far as the things you just mentioned, is there anything I can get?
"After talking about the motor, let's talk about energy supply. We contacted many domestic manufacturers, but they were unable to provide batteries that meet our requirements. Finally, Harbin Institute of Technology provided a set of laboratory products they are currently researching that barely met our requirements. , But the performance is not very stable."
Tan Zhenhua interjected: "Are Ni-MH batteries used?"
Song Wenhua looked at him in surprise this time and said: "Yes, I didn't think Xiao Tan even knew this. It is indeed a nickel-hydrogen battery. Its energy storage capacity is 1.5 times that of the nickel-cadmium battery you used last time. Around it is the battery with the highest energy density we can find.
It’s a pity that even so, there is still some distance from Xiao Zhan’s 20-minute blanking time requirement. Today’s experiment result is twelve minutes, but I want to adjust the power supply control system to 15 minutes later. It is still possible. "
Zhan Nuozhu glanced at Tan Zhenhua, and shrugged: "Well, it's OK to do it for 15 minutes, Professor Song, continue."
Professor Song nodded and said, "Okay, let's look at the control system. This is the core part of this quadcopter."
