Chapter 29: Spy camera

Since everyone can't accept the facts that Tan Zhenhua knew by birth, then he can only be considered a genius.
Or Liu Dakai said: "Well, Tan Tiancai, what you said just now, we all believe you, then let's talk about something specific, such as your drone, and the Maoxiong you just said that the science and technology tree is wrong. What is it again?"
Tan Zhenhua laughed: "Let’s talk about this science and technology tree first. This word was created by me, which means the development of human science and technology. Every new technological achievement needs to be built on the basis of several predecessor technologies. In summary, it is like a tree, growing up little by little, and what this means is, in fact, I think that these new scientific and technological achievements conform to objective laws and exist objectively. In other words, after the basic technologies that constitute the new technology reach a certain stage of maturity, as long as you follow this development path, you will inevitably discover or create this result, but it needs to be done by the right person at the right time. Finding it and discovering it is like walking along a road in the dark, lighting up a street lamp all the way. Of course, if you walk along a different road, it must be a different lamp."
This metaphor is really vivid, and several people immediately made up for it, and they couldn't help but nod slightly. Zhan Nuozhu praised: "Well, the new word kid invented is a bit interesting.
Tan Zhenhua accepted Zhan Nuozhu's compliment without blushing, and immediately praised himself: "Well, I think so too, because I am a genius." After he finished speaking, he saw his father Tan Ming. The eyebrows were erected, and he quickly changed the subject: "However, the electronic technology of this bear family can be said to have gone in the wrong direction, so I said they clicked the wrong technology tree."
"Oh? Why do you see?"
"Of course it's from our firm's roots and on the radar."
"Oh, Tan Datian, when have you studied radar again?" Representative Wang teased.
Tan Zhenhua said, "I really have research. The radar technology in my mind is 40 years ahead. It's a pity that even if I take it out now, it's useless. We can't make it out of our current industrial base."
"Hehe, I don't have any research, but I will analyze it. The source of my analysis is an article in "Aviation Knowledge". It said that the pilot of the Mao Xiong family defected to the country in 1976 in the MiG 25. thing."
"Well, it's not a secret. Later, the U.S. disassembled the plane and studied it thoroughly. This stainless steel lump can fly double 3s, which is really scary." Zhan Nuozhu said. What he said this time is all true. The MiG 25 of the year can be said to be a lingering shadow on the hearts of all the soldiers of the rabbit family. There is no other reason. The guy in the rabbit hand wanted to take down the MiG. 25, almost impossible!
The MiG-25 of the Mao Xiong family is the most secret project in the history of the Mao Xiong family's aviation forces. Its main mission is to intercept and destroy enemy reconnaissance and bombers. The designer positioned it as a high-altitude high-speed aircraft.
In 1961, the MiG-25 prototype set a ceiling of 22,670 meters and a world record of 3,000 km/h in a test. It was known as the Double 3. At that time, no aircraft in the world could achieve this performance.
As soon as this number came out, it was not just the rabbits, even if they were as powerful as an eagle sauce, they were frightened, because they did not have a fighter to be their opponent!
Therefore, the Yingjiang family's intelligence agency tried their best to figure out the true performance and characteristics of the aircraft, but after spending a lot of manpower and material resources, it only got some fur that Mao Xiong family deliberately leaked.
However, what I didn't expect was that just when Yingjiang was helpless, her joy fell from the sky. One day in September 1976, a captain named Belenko from the Mao Xiong family defected in a MiG-25, and the plane landed at Hakodate Airport in Hakodate!
After World War II, the country was the good son of a U.S. native. As soon as this happened, of course he had to call his father, the U.S. native. Needless to say, of course, the Americans disassembled the MiG 25 inside and outside for a good study. They played around until mid-October before returning the plane to Teddy Bear, and published a series of public reports. The article introduces this aircraft, and there are many ridicules and derogations. Now, the MiG 25 is a leak, and its performance parameters have become the content of popular science magazines.
"This is not the point of what I said. The point is that the article said that the MiG 25's nose radar can cook rabbits when turned on. The Americans opened it and saw, oh, it was actually a tube."
When these words came out, everyone in the house became calm, why? Because the rabbit’s current radar is also full of electron tubes.
"What's wrong with the electronic tube? The electronic tube has the advantages of the electronic tube. It has strong anti-electromagnetic interference ability and high power." Tan Ming blushed and argued roughly. "
Tan Zhenhua does not eat his father's set: "You are the legacy of Mao Xiong's family!"
Tan Ming was confronted by his son in front of him, and his face was immediately lost. He shouted: "What do you know about you kid? You think you know electronics if you can play with a radio? What do you know about radar?"
Tan Zhenhua said with a smile: "Dad, don't worry, listen to me and finish talking. I don't understand radar, but I can analyze it. Look, this radar is installed on airplanes, right, I understand. Yes, as long as everything installed on an airplane can achieve the same function, it must be as light as possible, right?"
"That must be true."
"Then dad, if you replace these tubes with transistors or even integrated circuits, how much weight can this radar save?"
"These weights, even if they are directly converted to the fuel carried by the aircraft, can they leave the aircraft empty for more time?"
"Also, radar is not only based on power consumption, but also on specific implementation functional parameters, such as detection range, number of tracking targets, number of locked targets, etc., that is, conversion efficiency. All of you here are experts, so I won’t talk about it. Now, if you talk too much, I know one thing. The guy with the tube must consume a lot of power and have a very poor conversion efficiency! This means that in actual combat, the time he can keep on turning on is short, because If it is turned on for a long time, the energy supply of the aircraft itself and the heat dissipation of the radar itself will surely have problems! If it cannot maintain a certain turn-on time, no matter how good the radar is, the combat effectiveness will be greatly reduced!"
As soon as I said this, the seats were all silent, yes, all of you here are veterans playing radar, how can you not know this?
For a long time, Wang Zetian sighed: "Everyone knows the truth, but unfortunately, there are some things that you can't think you can do. The devices can't keep up, and the gods can't keep up! Zhenhua, let's not talk about the troubles of the Mao Xiong family. Or just talk about your drone, but you can talk about it, where is the room for development of this thing?"
Liu Dakai also picked up the thing and put it in front of everyone.
Speaking of this, Tan Zhenhua immediately got his spirits, and saw him pretentiously asking: "Everyone knows that this thing has changed?"
Zhan Nuozhu also joined in for fun, and said, "The details are unknown."
Tan Zhenhua said: "This thing can be large and small, and can rise and be hidden; when large, it soars above nine heavens and can be used as a thunder strike; when small is hidden, it can be peeped and explored; when rising, it soars in the universe, hidden Lurk in the waves."
Tan Ming slapped him on his forehead and drank: "Talking!"
Tan Zhenhua said, "Oh yes," he said, "Dad, do you lightly and be stupid? I'm your son."
Everyone was happy, and Representative Wang said, "Okay, okay, don’t be poor, know that you’re a genius, right? You don’t need to say what the purpose of this thing is, you just talk about how it is done, and there is a future. The development trend is good.
Tan Zhenhua constricted his smile and said sternly: "Well, since Representative Wang said it, I will briefly introduce the situation. At present, I call this machine No. 1 in front of me. It was actually built to verify the principle of the entire system. At present, it seems that the principle verification has basically passed, at least, it is flying.
Of course, many problems were found in the principle verification.
The first one is the battery problem. I currently use Ni-Cd rechargeable batteries from the 755 factory. This battery can be recharged more than 100 times, which can effectively reduce the cost of use. However, the shortcomings are also very obvious, that is, the capacity is obviously insufficient. The first test flight , I only lasted less than 5 minutes. I heard that there are already higher energy density Ni-MH batteries in foreign countries. If that technology can be used, it can be increased to 10 minutes or more with other improvements. Achieved.
Then there are the structural parts of the body. At present, it can only be regarded as a piece of work. In the future, it should at least be processed by molds. Using engineering plastics as the body material can not only reduce the weight, but also increase the strength of the body. If it is for military use, I recommend using carbon fiber directly. Lighter and stronger. At the same time, it is necessary to restructure the design according to the circuit layout inside.
Then comes the power part. At present, the ferrite permanent magnet motor I use is cheap, but the shortcomings are also obvious, that is, low efficiency and poor load capacity. Master Pan helped me make this motor, but I don’t know the design of the motor myself. I read a few books and made a fool of myself. So the efficiency is not high. It may be much better if I switch to an expert. I heard Now the Japanese people are studying iron-based rare earth permanent magnet materials. If the research is successful, the performance of the motor can be greatly improved.
The last is the flight control. There are two most important parts of the flight control. One is attitude perception. I am using an electronic level gauge. The accuracy is too poor. I hope I can have the opportunity to replace it with a three-axis gyroscope in the future so that the attitude control can be achieved. It is much more accurate, and the flight control algorithm and CPU are too low now, but the condition is that, if there is a chance in the future, if the model can be finalized, you can fly more, fly out the flight envelope, and gradually improve the flight. Control algorithm.
As for the purpose, I think it can only be a toy for now, because as far as I know, there is no suitable load for it. However, with the advancement of technology, this gadget can be made smaller or larger. The spare time is longer and the noise is further reduced. It is very good to be a frontline investigation. "
"Actually, it can do a lot of things now," Zhan Nuozhu said suddenly, then took out an item from his pocket, put it on the table, and said, "Can it move this?"
"Fuck, what is this? Oh, this is the legendary spy camera, Chief Zhan, is it really alright for you to openly take it out like this?"
