Luo Chaoying asked, "What is a radical change?" ”

Lin Yuan said: "I know what you mean, you want to replace them with shells with strong explosive power, but this is not very useful, after all, their aiming accuracy and firepower density are not high, so it is useless to change the shells with strong power, so I think we might as well design a set of automatic cannons with extremely high hitting accuracy." ”

Luo Chaoying asked, "Automatic cannon?" How to design? ”

Lin Yuan said: "We brought a spare set of airborne radar over, and then used the radar to search for the target, and precisely tracked the target, after the radar tracked the target, passed the location of the target to our artillery, and then used the artillery to attack the enemy's warship." Luo Chaoying thought for a moment and asked, "Pass the location of the target to the artillery?" How to transmit? ”

Lin Yuan continued: "For example, a radar like a mechanical scanning antenna, after the radar finds the target and turns into a tracking state, it will measure the orientation and speed of the object, and calculate the acceleration according to the speed per unit time, and pass the calculated results to the antenna base of the radar through a series of mechanisms, so that the antenna base also rotates at a certain angle, so that the beam emitted by the radar is exactly aimed at the target." ”

"If we connect the signal that controls the rotation to other branches, for example, a servo motor, and the motor controls the high and low machine and the direction machine of the artillery, the signal of the motor can control the steering of the artillery, and then combined with the ballistic characteristics of the shell, we can realize the automatic control of the artillery by the radar."

Luo Chaoying thought for a while and said: "Your idea is very good, but this system needs a lot of key components, I don't understand the radar, as well as motors, automatic control, etc., you need to find a few more experts, and we can work together to make this automatic cannon system." ”

Lin Yuan said: "I will help you find an expert, and our related equipment will also be shipped, so you can rest assured." ”

Luo Chaoying said: "I want to give you a preventive shot in advance, this automatic cannon system seems simple, but its difficulty and complexity have far exceeded any kind of weapon we have designed and manufactured before, and there is a great possibility of failure in development." ”

Lin Yuan nodded and said, "It's okay, if we fail, we'll think of another way." ”

Lin Yuan left the Machinery Bureau, first asked the location of the Russian fleet, and knew that they were still on the surface of the Sea of Japan, so he asked the Beijing ship to transport a set of airborne radar from Lushun, and the experts and engineers in the same company, the Beijing ship in Lushun thought twice, and decided to transport the equipment from Port Arthur to Tianjin by sea, which would take a day.

As soon as Lin Yuan returned to Beijing from Tianjin, he went to find the newspaper Shen Wanqing, and found that Xu Feng was also here, and the two of them were sitting in front of a computer, and there were several pictures on the computer screen, and the picture was the outline of the person's face, Shen Wanqing asked Xu Feng: "Look at the face shape here, which one is most similar to Sakurai Wakami?" ”

Xu Feng pointed to one of them and said, "This one is the most similar, but the chin should be sharper." ”

Lin Yuan looked at them for a while, then asked behind them, "What are you doing?" Shen Wanqing said: "We are painting Sakurai's appearance. ”

Lin Yuan asked, "But you're not painting?" ”

Shen Wanqing laughed and said, "You think about what a person looks like in your mind, and then describe it accurately. ”

Lin Yuan thought about it, and then realized that although the appearance of a person was in his mind, it was very difficult to find some words to describe it, so he shook his head and said with a smile: "This can't be described, it's too difficult." ”

Shen Wanqing said with a smile: "That's right, when people remember other people's appearances, what they remember is the general appearance, and when they see this person again, the brain automatically reacts to who this appearance is, so drawing a portrait according to memory is like this, show a person a few sets of pictures, and then let that person pick out the one that best fits the memory, and then modify it according to the memory." ”

Lin Yuan nodded, and Xu Feng asked, "Are you in a hurry?" ”

Lin Yuan said with a smile: "It's okay, you continue to draw, I came to ask Wanqing to write a manuscript." ”

Xu Feng smiled: "Then wait for us to draw Sakurai Wakami." ”

Shen Wanqing said: "We don't have to wait, in this way, you tell me what manuscript you want me to write." ”

Lin Yuan said: "Please write a press release saying that Ryukyu has sold us the technology of automatic tracking cannons, and now the equipment has arrived at Port Arthur and will be shipped to Beijing in the near future." ”

When Xu Feng heard this, he said in surprise: "What? Auto-tracking cannon? Got this kind of thing? ”

Lin Yuan said with a smile: "When I was showing it in the Ryukyus, I once showed them the artillery that was stably aimed with a gyroscope, and I called it an automatic tracking gun at that time, and now when I write it like this, they will definitely believe it." ”

Shen Wanqing nodded and said, "It's good, I'll be able to see the newspaper tomorrow, but why do you want to send such a message?" ”

Lin Yuan said: "Do you remember the day I asked Wang Yuding to make a big deal about his leakage? ”

Shen Wanqing said: "Of course I remember, you also said that it was a foreshadowing planted by you. ”

Lin Yuan said: "My plan is like this, the Japanese and Russians will be very interested when they hear the news of our automatic artillery, because the Russian fleet is coming, so they will definitely spare no effort to collect information about the defense of Dagu, and the automatic cannon is something they cannot miss." ”

"If the Japanese want to know the situation of the automatic cannon, they will definitely start from the station, and they will definitely find someone who can leak the news, I let Wang Yuding make a big fuss, that is, let the Japanese know the Tao, he knows the situation on the train, so the Japanese will definitely go to him, so that we can find out the Japanese spy, maybe Sakurai Wakami will be found."

After Lin Yuan finished explaining the matter, he left the newspaper office, it was already dark at this time, and Lin Yuan had almost just sat down when someone came to report: "Wang Yuding is here!" ”

As soon as Wang Yuding entered the door, he said, "Lin Shuai, didn't you tell me to pay attention to who is looking for me?" I went to the teahouse at noon to tell me about the leak, and in the evening someone came to my house and brought me two jars of 50-year-old flower carvings. ”

Lin Yuan asked, "What did he tell you?" Wang Yuding said: "He is the new shopkeeper of Fuman Restaurant opposite the station, the restaurant is open, please take care of it." ”

After hearing this, Lin Yuan thought to himself: "It turned out to be walking around in the business field. So he smiled and said, "It's not such a person, you pay attention and tell me the person who wants to know what's on the road." ”

After Wang Yuding listened, he nodded and went, but it didn't take much time for him to turn around and come back, and as soon as he entered the door, he said nervously to Lin Yuan: "Lin Shuai, I remembered, the person who came to me today just wanted to know what people were on the train!" ”

Lin Yuan hurriedly asked, "What's the matter, tell me quickly." ”

Wang Yuding said: "When this person was talking to me, he casually asked me, what are the things on the train? ”

Lin Yuan hurriedly asked, "Then how did you answer him?" ”

Wang Yuding said: "I was attentive at the time, so I asked him, what are you doing with this?" He said that if the train was carrying goods, he would find a coachman and a carriage to help transport it, and if there were people on the train, he would prepare food in advance, and wouldn't he be able to make a lot of money. ”

Lin Yuan asked again, "Then did you promise him?" ”

Wang Yuding said: "I told him that he couldn't say anything in the car, and he left without asking. ”
