Chapter 11 Aviation Instruments Zhao Jinli entered Sichuan

Before leaving the airport, Zhang Zhimu said to Li Wei: "Li Wei! You can't always stay at the airport, our march into Liaodong this year is a test for your technical arms. Especially this one by land. All the equipment and fuel had to be transported by road, which was a lot of pressure. Such a long distance is a test for our cars, artillery trucks, armored personnel carriers, and tracked tractors. Maintenance personnel and spare parts must be able to keep up. ”

"Huh! Mr. Zhang, after so many years, we already have a group of people, and I just need to urge them to do these specific things. Especially after the students of the technical school gave us, they have been very capable in the past two years. Each of them can drive a car and make repairs, not only technically, but also without ambiguity. I still have a wide range of knowledge, and it is easy to cultivate. Now I'm a strong soldier. This time, we divided all the heavy artillery into the armies. But the rocket artillery division we formed was even more powerful. I'm waiting to give it a try when I enter Liaodong this time. Li Wei still looked very aggressive. Zhang Zhimu knew that Li Wei was actually careful, and he didn't have to worry too much about his affairs.

On the car back, Zhang Zhimu said to Yang Chang: "The instruments they use on the ship and on the plane, you have to focus on it." ”

"Don't worry, Mr. Zhang, we now have a group of people like General Li Wei. After several years of training, they are all hands. When it's okay, everyone communicates with each other, and they improve quickly. I want to do something about it now. I've also seen that technicians, as long as they are given conditions, it is beneficial to give them a little pressure. ”

"That's good, talent is our most valuable asset, we should cherish them." Zhang Zhimu said, "By the way, let me tell you about aviation instruments!" ”

"Good!"

"Let's talk about the horizontal angle of the plane that measures takeoff and landing. I guess it's not too difficult to measure the horizontal angle with a leveling device. But I want you to use a small display, in the middle of the display with a line to show the horizontal line, when the nose down, you have to have a corresponding line to show the downward angle, the nose up according to the upward parameter to show an upward pattern, to give the pilot an intuitive parameter. In addition, if the left and right sides of the aircraft are not level, it should also be displayed with an image. This allows the pilot to know the attitude of his aircraft from this display. It's a job that requires a little bit of effort. In the future, if possible, the altitude, speed, and fuel are also displayed on the display. In this way, the pilot can take a look at the monitor and everything will be clear. ”

Mr. Zhang's meaning is to display all the data detected by the instrument with this display. Technically, we can do that, but it takes some time. Yang Chang said confidently, "Those of us who are engaged in the display can participate in this work." They're familiar with displaying something on a display. ”

"You're right." Zhang Zhimu asked again, "How's your radio detector doing?" It's a very important thing for our ships at sea, and if it's done, you're going to have to develop a high-power radio detector. On the coast, we have built a radio detector to clearly detect the positions of ships on the coastal sea, and it will be much more convenient to guard the sea in the future. ”

"They're experimenting." Yang Chang said, "I want them to try to increase the emission frequency as much as possible, so that the emission lobes will be narrower, as you said." However, the higher the frequency, the worse the stability, and the more powerful the interference. ”

"Of course. A small change in the parameters of the higher frequency will have a big effect, including the distribution parameters between the devices, as well as the direction of your wiring. And your devices, when it comes to high-frequency operating parameters and low-frequency time, there is also a big gap. Later, when it comes to the microwave band, many of our devices can't work, and we need to use cavity devices. That's another question. You can use the technology you can use now to achieve your goals! ”

Zhang Zhimu knows that the radar can only be better if it uses a higher microwave frequency band. However, the courses I studied in school, such as "Microwave and Antenna" and "Electromagnetic Field and Field Theory", basically did not use them again after graduation, and it was very difficult to recall. Besides, these two courses are also difficult to learn in professional courses, and I can only barely pass what I learned. It's really hard to sort things out on your own right now. But Zhang Zhimu also knew that even if he could give them a little advice, it would be much better than exploring it from scratch. Therefore, no matter how difficult it is, you must sort out as many things as possible, that is, point them in the direction.

Li Yunhe, who had been sitting next to him and had not spoken, suddenly asked, "Yang Chang, I read your printed textbooks on radio. Some of it is all math. I think that except for the people left by Mr. Lu Bingyi to specialize in theory, that is, you have a high level of mathematics in radio. ”

Before Yang Chang could speak, Zhang Zhimu smiled and said, "Hehe! That's a little bit. Let me tell you, radio technology can be challenged in all areas of mathematics. Yang Chang: They still have a lot of math stuff. ”

Yang Chang said: "Oops! I don't think we can learn any worse mathematics than Mr. Lu Bingyi's students who study mathematics! And we've been applying it, and they've been learning with us about all the transformations and things you talked about. ”

"Don't compare yourself like that," Zhang Zhimu said, "and the mathematics will become more and more detailed in the future." What you need is a face-to-face, and Mr. Lu's students are going to study deeply and thoroughly in a very small field. The goals are not the same. The calculations of our bridges are all made by them in applied mathematics. In the future, we will have to replenish personnel in mathematics and physics, which is to lay the foundation for the future. ”

"Only now do I feel that Mr. Zhang, what you said was too right. No amount of effort is enough to train people. Li Yunhe said, "You see, we graduate so many students every year, it's not enough to grab." In the future, no large-scale factories will be built on the kiln side, and as many colleges will be built as much as possible. It will build Yaogang into a city composed of universities. ”

"Yunhe is right," Zhang Zhimu agreed, "In the future, the positioning of our kiln is to build a science, education and cultural center." At this moment, Zhang Zhimu's heart suddenly brightened. It's time to reposition the kiln. In the past, the construction of the kiln gang was always patched, and the top-level design of the kiln gang was not carried out from a higher level, so it was always passively pushed. This time I went back to discuss with Lu Bingyi and Huang Yukun, and the construction of the kiln gang should be re-planned.

Since Mr. Lu Bingyi personally led a team to the Tao River to inspect the water diversion plan, the planning plan for the kiln gang was not completed.

Lu Chengxiang, who arrived in Fujian, sent a request to transport a batch of cowhide bags that originally contained cement to Zhenjiang. Because the fleets to Sulu and Annam will soon return home. Lu Chengxiang suggested that all grain ships should be transported to Huai'an and the mouth of the Yellow River as much as possible, and from there they could be transported back to Shanxi and Shaanxi by tugboats. The ship carrying guano stopped at Zhenjiang, because half of the guano was kept for use in Henan, Anhui and other places, and half was transported back to Hetao, Shanxi. What Lu Chengxiang means is that these guano droppings are used everywhere to see how they are used. If it works, you can go to Sulu and ship back in large quantities of guano right away. Lu Qi and Fan Song telegraphed that there was a lot of guano over there, and a large ship full of 5,000 tons could not see how much guano was missing, and there were many islands in Sulu that were guano islands.

Since the canal from Kaifeng to Huai'an is not open now, the cowhide bags can only be transported to Kaifeng by boat, and then transported ashore to Huai'an by car and horse, and then transported to Zhenjiang by boat.

Zhang Zhimu knows that this method of using cowhide bags to pack guano is very good, because as long as the cowhide bags are sealed with a sealing machine, there is basically no taste, and it is easy to divide when distributed to various places, and it is more convenient to use at home when distributing guano to people.

However, Zhang Zhimu suggested that this guano is a phosphate fertilizer, which should be used in conjunction with chemical fertilizers such as ammonium nitrate. Five thousand tons is a lot, but the distribution to various places is pitiful.

Zhang Zhimu knew these specific things and stopped asking about them. Since Chen Yufeng and Ouyang He never came back in Datong, Zhang Zhimu stayed in the command center.

On this day, as soon as Zhang Zhimu came to the command center, Liu Yun greeted him with a telegram, "Mr. Zhang, take a look!" Zhao Jinli called. ”

"Hmmm! Zhao Jinli: How are they doing? Zhang Zhimu asked as he took the telegram.

"It went very well! This kid is okay. "Liu Yun returned to the command center to preside over the work of the General Staff, there are many things, but he has also trained people, and now he is more stable and sophisticated. The affirmative answer is also full of love for Zhao Jinli.

Sitting down and reading the long telegram sent back by Zhao Jinli, Zhang Zhimu felt that there was nothing wrong with Zhao Jinli's use. Zhao Jinli sorted out the situation in Sichuan in a very clear manner.

After Zhao Jinli's original First Army was expanded into the First Army and the Ninth Army, the Ninth Army was left under the command of Ningde to be responsible for the defense of the west. Zhao Jinli led the First Army to Chencang, crossed the Qinling Mountains through the newly expanded Chencang Road and came to Hanzhong to rest, and Lin Feng and the Tenth Army, which had been expanded by the Third Army, also went to Hanzhong to join them and train together. In fact, Zhao Jinli and his first army also had a way to enter Sichuan from the Hehuang area, but the road there was more difficult to walk. Over there, Zhao Jinli and they couldn't carry a lot of heavy weapons. Therefore, after weighing it, they still followed Zhang Xianzhong's suggestion and entered Sichuan from Hanzhong.

Although Zhang Xianzhong repeatedly urged them to enter Sichuan as soon as possible, Zhao Jinli knew that he was not prepared and could not act. It was not until all the officers who had been trained at the kiln post returned to the team, and the officials and police officers assigned to them were all in place, that Zhao Jinli commanded the team to march towards Sichuan. There are some waterways, and the boats of the kiln can help them get the materials they need. However, the road into Sichuan is still very difficult. Although Zhang Xianzhong also sent people to repair the road, it can only be said that it is better than before, and the speed of the large group of people coming in is extremely slow. Especially Zhao Jinli, it is very difficult for them to walk on such a road with heavy weapons. But Zhao Jinli would rather re-send sappers to open the way, and insist on bringing heavy weapons. He knew that he couldn't help them when he entered his home in Sichuan, and he needed to solve all the problems on his own. Therefore, Zhao Jinli, they marched all the way to a difficult and very slow speed.

Fortunately, Zhang Xianzhong sent someone to respond, and there was no armed interference along the way. They divided their troops into two routes, went through Long'an Mansion, Shunqing Mansion, and Baoning Mansion with great hardships, and when they arrived at Chongqing Mansion and Chengdu Mansion respectively, Zhang Xianzhong's army had been divided into two routes, all the way to the west and the other to the south, and started a war against the rebel Tusi of the Shuixian clan.

Before Zhao Jinli entered Sichuan, Zhang Zhimu talked to him with Chen Yufeng and Ouyang He.

Zhang Zhimu told Zhao Jinli that the nationality issue is a very complicated issue. Our Ming Dynasty currently has two hidden dangers, one is the Tusi of all ethnic groups in the southwest, and the other is the Manchu Qing in the northeast. The just-concluded Southwest Tusi Hao'an Rebellion lasted nine years, and the war lasted until the third year of Chongzhen (1630). During the Apocalypse, Sichuan Yongning (Xuyong) Xuanfu Si Hao Chongming and Guizhou Shuixi (Dafang area) Xuanfu Si Anwei's uncle An Bangyan launched a rebellion. In September of the first year of the Apocalypse (1621), Gao Chongming started an incident in Chongqing and surrounded Chengdu for more than 100 days. An Bangyan raised troops in February of the second year of the Apocalypse and besieged Guiyang for more than 200 days. At that time, there were more than 400,000 people who fled into Guiyang, and after there was no food in the city, the army and the people ate each other, and in the end there were only more than 20,000 people left in the city. Therefore, the power of the Southwest Toast cannot be underestimated. Now there is Zhang Xianzhong using coercion in the front, after we pass, if we want to govern there for a long time, we can't rely entirely on coercive means, we must pay equal attention to grace and power. It is necessary to let the local people see hope and get benefits. But I agree not to be soft on those who resist. Remember, there will be no permanent tranquility there if the toast system is not completely broken. Once those toasts have rights, their ambitions will swell, and they will not be psychologically willing to obey the rule of our Han people, and their sense of resistance is from the heart. You have to spread more information to the people there and tell them that our policy is that all nationalities are equal. We treat all ethnic groups who are willing to cooperate with us equally. Our government there also needs to absorb some local people who are willing to cooperate with us. It's also a good idea to raze it. They understand the local situation, cooperate with them, and never discriminate against them. All the officers and men of your army must do a good job in this point and let everyone pay attention to it. I guess militarily, they are not our opponents. You're fighting more political battles.

Zhao Jinli listened and nodded.

Chen Yufeng said: "At the beginning, you must fight with majesty, otherwise your gentle methods will be regarded as weakness." I think Zhang Xianzhong can kill on a large scale, which is not a good way. ”

"Huh! I agree with Mr. Chen's words. Ouyang He said, "You have broken the right of toast that has been passed down from generation to generation, and people will inevitably fight with you." Everything can only be discussed when there is a high or low level in terms of force. In the end, peace was made, and it was also fought. As long as they are obedient, we will treat them well, otherwise they will be severely punished and resolutely not polite. Without Wei, they can't know En. ”

Zhang Zhimu agreed to use forceful means, and if he wanted to solve the southwest problem in a short time, he could not use forceful means. Zhang Zhimu knew that in the original history, Wu Sangui almost exterminated the ethnic minorities in the southwest, and it was only then that the southwest was completely stabilized. Although Zhang Zhimu did not agree with that kind of exterminating practice, he also knew that this was a life-and-death contest, and it was not okay to be merciful. At the beginning, Zhu Yuanzhang, the Taizu of the Ming Dynasty, adopted the method of divide and rule, and set up a total of more than 300 toasts in the southwest, and the territory of those big toasts was divided into many small toasts, and those who were not convinced often had to launch wars to conquer and annex. But some toasts are very influential, such as the Shuixian clan that uses the method of marriage everywhere, and as soon as they rebel, many toasts will follow.

However, Zhang Zhimu analyzed that the southwest toasts made a very wrong judgment this time. He thinks that the Ming Dynasty is no longer good, this Zhang Xianzhong is an outsider in Sichuan, and he is not popular with Sichuan people, they think that this is a good opportunity for them to rebel against independence, so they really raised the banner and rebelled. They live deep in the mountains, and the news is too closed, and they don't know that now there is a force that they can't compete with. And now Zhang Xianzhong has the backing of the Yaogang people, and he is trying to do something for the Yaogang people, waiting for this good opportunity to kill them.

After reading the telegram handed over by Liu Yun, Zhang Zhimu said: "Zhao Jinli, they can be regarded as stepping into Sichuan. It depends on how he gains a foothold in Sichuan and the southwest. However, send a telegram to Zhao Jinli and Zhang Xianzhong, pay attention to capture more prisoners, the roads in Sichuan are too poor, and we need people to build them. That kind of plank road has to be the kind of road that you build that can lead to cars. If you need cement, you can transport it from Hanzhong. By the way, tell them that it is more stable there, and we will send someone into Sichuan to design the road into Sichuan in detail. In the future, if we want to completely change the situation there, we must build high-grade roads and railways into southwest Sichuan. ”

Liu Yun also agreed: "That's right! Mr. Zhang. As long as it was a road or a railway, the telegraph and telephone were connected. The people there also feel that they are one family with us, and we understand each other more, so there is not such a deep estrangement. The people will also benefit from this, and they will not follow in the trouble. ”

"Also, urge Fan Chengkun and them a little, the Yangtze River waterway must be dredged as soon as possible. The opening of the Yangtze River waterway is very important for us to govern Sichuan. Zhang Zhimu commanded.

"Yes, Mr. Zhang."

At this time, a staff officer ran over with a telegram.

Liu Yun took the telegram and glanced at it, and hurriedly handed it to Zhang Zhimu.

The telegram was sent by Qin Peng, and it read:

"Command center: Our army arrived at Zhaoqing Mansion, and the Zhaoqing Prefect led the army to close the city gate and not allow our army to enter. Our troops approached, and the city's artillery opened fire on us with bows and arrows. We tried several times to no avail. I ask for permission for our army to open artillery and attack the city! ”
