Chapter 736: Kou Kewang

"You see through it." Tan Zhenhua replied with an awkward smile.
However, in his words, the hidden little bit of embarrassment in his heart was not revealed: "I think so. Since I am one of the investors of "Flying Leopard", I have half of the shares and still own this. I have the exclusive right to export this fighter jet, so I can ask the designer and manufacturer of the product to design the aircraft according to my requirements? Brother Zhan, are you right? I intend to require the export-type "Flying Leopard" to be delivered within a specified time There is a certain state of technology, and Master Chen wants to catch up with this time schedule, and he can't do it without using some special methods—for example, working with IAI in flight control."
"You are nakedly intimidating!" Zhan Nuozhu pointed out Tan Zhenhua's sinister intentions unceremoniously.
Ben Fang's statement is a little softer: "Zhenhua, I think you are doing this to force Master Chen a bit?"
Tan Zhenhua didn't deny it, but sincerely said to Ben: "Teacher Ben, I can't force it, because I think the time window left for us is actually getting narrower and narrower."
"Oh? How to say?" Ben Fang asked.
Tan Zhenhua didn't rush to answer Ben Fang's question. Instead, he said: "The time window can be explained in the second step. I would like to first talk about why the problem of "excessive telex control system" should be solved as soon as possible. "
"Superfluous fly-by-wire control. This thing is not complicated in principle. It just transmits the action instructions given by the pilot to the various rudder surfaces of the aircraft with the original mechanical structure to control the flight attitude of the aircraft. , The original mechanical structure composed of a bunch of connecting rod gear nooses is removed, replaced with electrical signals, and the actuator is also changed to an electrically driven one. Further development on this basis can remove many of the original many that must be performed by the pilot. The programmed actions are made into standard procedures, allowing the flight control system to automatically execute these standard procedures after receiving clear instructions. This can greatly reduce the pressure on the pilots. Brother Zhan, I actually explained these to you last time, right? ?"
Zhan Nuozhu nodded. Tan Zhenhua indeed explained to him some simple principles and benefits of the fly-by-wire flight control system. In his understanding, this is equivalent to upgrading the aircraft from manual transmission to automatic transmission. He himself is the pilot. , Can fly at least the "Yun 5" and "Straight 5" models. I am very familiar with the control systems on these two models. The cabins of those two cargoes have a bunch of transmission mechanisms composed of connecting rod gears. It's really hard to drive.
"There is no doubt that the flexibility and action response time of the aircraft using the fly-by-wire control system is much better than that of the traditional mechanical transmission structure, which also means that the fighter can obtain more superior maneuverability; and for a fighter In other words, because the fly-by-wire control system automates many standard procedures, it can free the pilot from a large number of repetitive and possibly error-prone standardized flight actions, such as leveling, maintaining flight altitude, etc., and focus more on manipulating others. The equipment-such as advanced radar and fire control systems, weapons or electronic warfare pods. This is the first reason I want to control by telex. It represents the future of fighter control."
After a pause, he went on to say: "The second reason is more realistic. Since teletransmission control involves the transmission and processing of electrical signals, it must use semiconductor and electronic technology, and because of the reliability of the current circuit system And the need to increase safety redundancy backup, it is also necessary to install more than one set of such control systems on an aircraft to ensure the safety of the aircraft, that is, the
redundancy
just mentioned, such as installing 4 sets of mutually independent electric The transmission control system is called "four more degrees."
At this point, Tan Zhenhua sighed: "Teacher, I will answer your question about the time window just now, because if it is not forced, I am afraid that the gap will become bigger and bigger, until we finally have no courage to catch up. Now, if I push it like this, maybe it can attract enough attention in the country, then I will be satisfied, teacher, do you know what I felt the most during the time I was studying in the United States?"
Now even Zhan Nuozhu became a little curious, and asked Ben in unison: "What is it?"
"The level of semiconductors and electronics in the U.S. has developed too fast." Tan Zhenhua said: "For example, at Stanford University where I am studying, a major project underway is to spread across 33 square kilometers and use various The more than 5,000 computers in the structure are all connected together to enable them to communicate with each other. Teacher Ben, do you know what this means?"
Ben Fang's face suddenly changed: "This means that if this technology is applied to the military, they will have instant messaging and battlefield information management capabilities, and the battlefield range that this capability can cover will be very large. "
Tan Zhenhua nodded and said: "Yes, teacher, you can see clearly, but this is only a small aspect. Do you know the Z80CPU? It is the one I installed in a 4-rotor drone. This CPU has only been out for a few years. But in the United States, its performance has fallen far behind. At present, 32-bit CPUs have been put into testing in the civilian market. It is about to be mass-produced. The computing power has reached hundreds of times that of the Z80. You can understand the help of powerful CPU for information processing, right?"
Ben Fang’s face became more solemn, and Tan Zhenhua continued:
I also know that Texas Instruments launched a special DSP computing core TMS32010 last year. This chip can be said to be designed for computing. It can be used in one instruction cycle. It can complete one multiplication and one addition, and is used for digital signal processing. It has several times or even dozens of times the performance of current general-purpose CPUs. What does this mean?"
"It means that this chip can perform more Fourier transform calculations in one cycle. If it is applied to radar, the back-end filtering and signal processing capabilities of radar can be a step up to the current level of technology. The refresh rate and resolution will be greatly improved, and both the detection distance and the detection accuracy can be increased by an order of magnitude." Ben Fang's face is so dark that it can drip ink.
"Teacher Ben, you see, this is the scaly claw that I have learned in less than a year in the United States, and these are the technologies that China needs to spend a lot of effort to catch up with. I said bluntly, If we keep blindly working behind closed doors, the gap between us and the United States will be widened."
Ben Fang was still frowning and thinking, but Zhan Nuozhu couldn't help but interject: "But Zhenhua, we all know the fact that we are behind, but we are not behind for a day or two. The conditions were so difficult back then. Two bombs and one star..."
Tan Zhenhua interrupted his words and said sternly: "Brother Zhan, you mentioned "two bombs and one star". Well, let's talk about this "two bombs and one star". There is a fact that I must remind you that any engineering application First of all, it is inseparable from the breakthrough of basic science, and the "two bombs and one star" is a typical example. Without the discovery of basic physics, without Einstein's equation of e=mc2, and without the periodic table, it is impossible to have The achievements of "Two Bombs and One Star", it is a pity that in these basic discoveries of physics and chemistry, our Chinese people have made limited contributions. Newton said that the reason why he was able to discover "Newton's three laws" laid the foundation for classical physics. The foundation of learning is because he stood on the shoulders of giants. My understanding of this sentence is that Newton believed that the reason why he was able to achieve such great achievements was because many predecessors laid the foundation for him. And the people who laid the foundation are not just Britons."
Ben Fang suddenly raised his head and looked at Tan Zhenhua and said, "Zhenhua, you mean..."
"My meaning is very clear," Tan Zhenhua said categorically: "Importing, digesting and absorbing foreign advanced technology is not a question of whether we want to do it or not, but a question we have to do. In my opinion, there is no future for shutting down the country. Therefore, it’s even more undesirable to be self-proclaimed. The Chinese people invented gunpowder, but the Western powers developed this technology and even broke the closed gates of China with this, forcing our entire nation to experience an unbearable past. Now, it is they Given the foundation of modern science, we must respect this fact, but with their experience first, why can't we do the same thing?"
"Kou can go," Tan Zhenhua said softly, "I can also go."
