Open an aircraft carrier to fight against Japan

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 of little use, after all, their aiming accuracy and firepower density are not high, so you just change the shells with stronger power It didn't work either, so I thought, let's design a set of automatic guns with extremely high accuracy."

Luo Chaoying asked: "Automatic gun? How to design it?"

Lin Yuan said: "We transported a set of spare airborne radar, and then used the radar to search for the target and track the target precisely. After the radar tracked the target, it passed the position of the target to our artillery, and then used the artillery to attack the enemy. warship." Luo Chaoying thought for a while and asked, "Send the location of the target to the artillery? How do you pass it on?"

Lin Yuan went on to say: "For example, a radar like a mechanical scanning antenna, after the radar finds the target and switches to the tracking state, it will measure the object's azimuth and velocity, and calculate the acceleration based on the velocity per unit time, and pass the calculated result through a A series of mechanisms are passed to the antenna base of the radar, so that the antenna base also rotates at a certain angle, so that the beam emitted by the radar is just aligned with the target."

"If we connect the rotation control signal to another branch, for example, a servo motor, the motor controls the height and direction of the artillery, and the signal from the motor can control the steering of the artillery, combined with the ballistic characteristics of the shell, It will be able to realize the automatic control of the radar to the artillery."

Luo Chaoying thought for a while and said: "Your idea is very good, but this system needs many key components. I don't understand the radar, and there are motors, automatic control, etc. You need to find a few more experts. Let's work together. Only then can this automatic gun system be made."

Lin Yuan said: "I will find experts for you, and our related equipment will also be delivered, so you can rest assured."

Luo Chaoying said: "I want to inoculate you in advance. This automatic gun system seems simple, but its difficulty and complexity have far surpassed any weapon we have designed and manufactured before. The failure of the development Very likely."

Lin Yuan nodded and said, "It's okay, if it fails, we will think of another way."

Lin Yuan left the Machine Bureau, first asked about the location of the Russian fleet, and knew that they were still on the Sea of ​​Japan, so he asked the Beijing ship to transport a set of airborne radar from Lushun, as well as experts and engineers with him, to Beijing in Lushun. After careful consideration, the ship decided to transport the equipment to Tianjin by sea from Lushun Port, which would take a day.

As soon as Lin Yuan returned to Beijing from Tianjin, he went to the newspaper Shen Wanqing and found that Xu Feng was also here. The two of them were sitting in front of a computer. On the computer screen were several pictures. Qing asked Xu Feng: "Look at the faces here, which one is most similar to Sakurai Ruomi?"

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 drawing Sakurai Ruomi's face."

Lin Yuan asked, "But you're not drawing?"

Shen Wanqing laughed and said: "You imagine a person's appearance in your mind, and then describe it accurately."

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

Shen Wanqing smiled and said: "That's right. When people remember the appearance of others, they remember the general appearance. When they see this person again, their brain will automatically reflect who this appearance is. Therefore, drawing portraits based on memory Just like this, show a person several sets of pictures, and then let that person pick out the one that best fits his memory, and then modify it according to his memory."

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

Lin Yuan smiled and said, "It's okay, you guys continue to draw pictures, I'm here to ask Wan Qing to write a manuscript."

Xu Feng smiled and said, "Then let's draw Sakurai Ruomi."

Shen Wanqing said: "We don't have to wait, 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 guns. Now the equipment has arrived in Lushun Port and will be shipped to Beijing soon."

When Xu Feng heard it, he said in surprise: "What? Automatic tracking gun? Is there such a thing?"

Lin Yuan smiled and said: "When I showed them in Ryukyu, I once showed them a cannon that was aimed stably with a gyroscope. At that time, I called it an automatic tracking cannon. Now that I write it like this, they will definitely believe it."

Shen Wanqing nodded and said, "Okay, it will be published in the newspaper tomorrow, but why did you send out such a news?"

Lin Yuan said: "Do you still remember the day I asked Wang Yuding to publicize his leak?"

Shen Wanqing said: "Of course I remember, you still said that was the foreshadowing you planted."

Lin Yuan said: "My plan is this, the Japanese and Russians will be very interested when they hear about our automatic guns, because the Russian fleet is coming, so they will definitely spare no effort to collect information about our automatic guns. With Taku's defenses, automatic guns are something they can't miss."

"If the Japanese want to know the situation of the automatic gun, they will definitely start from the station, and they will definitely find someone who can leak the news. I asked Wang Yuding to make a big show, just to let the Japanese know that he knows the situation on the train, so Japan People will definitely look for him, so that we can find the Japanese spy, and maybe also find Takami Sakurai."

After Lin Yuan explained the matter, he left the newspaper office. At this time, it was already dark, and almost as soon as Lin Yuan sat down, someone came to report: "Wang Yuding is here!"

As soon as Wang Yuding entered the door, he said: "Shuai Lin, didn't you tell me to pay attention to who is looking for me? I went to the teahouse at noon to tell the leaked news, and someone came to my house in the evening and brought me two jars of 50 yuan. Aged Huadiao."

Lin Yuan asked, "What did he tell you?" Wang Yuding said, "He is the new shopkeeper of Fuman Restaurant across from the station. The restaurant has opened, please take care of us."

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 should be more careful and tell me anyone who wants to know what is on the car."

After Wang Yuding heard this, he nodded and went away, but it didn't take long before he turned around and came back, and said to Lin Yuan nervously as soon as he entered the door: "Shuai Lin, I remembered, the person who came to look for me today is People who want to know what's on the train!"

Lin Yuan quickly asked: "What's going on, tell me quickly."

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

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

Wang Yuding said: "I was careful at the time, so I asked him, what are you doing asking about these things? He said, if the goods on the train are goods, he can find a coachman and a horse-drawn carriage to help transport them. It’s a person who comes, so he prepares food in advance, won’t this make a lot of money?”

Lin Yuan asked again: "Then did you promise him?"

Wang Yuding said: "I told him that you can't just talk about what's on the car, and he left without asking."
