Chapter 101 How to lose weight

Nie Shiyu started school early, but today is Sunday. After finishing her homework at home, she ran to the shipyard to play. She happened to hear that military representatives were coming, so she came over to take a look. She happened to hear Qin Tao saying that he wanted to invite the general representatives. Of course I am very happy to come home.

While she was talking, she ran in and saw Zhao Ling standing inside wearing a military uniform.

“Wow, brother, this sister is so beautiful, much prettier than the sister last time!”

"What are you talking about?" Qin Tao's heart skipped a beat.

 “Which sister was it last time?” Zhao Ling had a smile on her face.

“Sister Cong Ju, I came here to work as a welding consultant. I originally said that she would come again after the New Year. Who would have thought that I have never seen her again. This sister, the room you live in is the room where Sister Cong Ju originally lived.”

Nie Shiyu acted very well, because the last time she faced Qin Tao and Cong Ju, she didn't perform well enough, and ended up making a big mistake. From that incident, she learned lessons and must not give anything to Brother Tao. Shame on you.

 “Sister Cong Ju?”

“He’s a master craftsman from a shipyard. He’s in his thirties, and his children are already good at making soy sauce.” Qin Tao quickly explained.

Zhao Ling glanced at him, feeling a little happy. Why should she explain this to herself? It means that he is afraid that he will misunderstand, and it means that in his heart, he still has status.

Is it because of his special status that he has an inferiority complex and doesn't come to see him? If this is the case, then forgive him.

“Have you settled in? Hey, why is there an extra little sister?” At this time, Meng Fansheng and Guo Wei came out.

“Well, hello, uncles.” Nie Shiyu was very polite: “I’m here to see my brother.”

“Qin Gong, it turns out she is your sister.”

"Yeah. By the way, you just arrived today. I'll take you out to have a nice meal and give you a refreshment."

 “No, there’s no need to do anything special for us, just the canteen.” Meng Fansheng quickly refused.

 The military representatives have a special status. If they are bribed by the sugar-coated bullets in the factory and lower their standards, something will happen. Before coming, the three of them all accepted the leadership's teachings not to make mistakes in this regard.

“Okay, let the canteen cook some dishes for you.”

There was a long distance from the dormitory to the cafeteria. Nie Shiyu was bouncing as she walked. Zhao Ling looked at her and always felt a little strange. The appearance of the two brothers and sisters were not similar at all!

Zhao Ling looked at the shipyard again. The hull of the dredger was still being welded. Countless sparks were flying and countless people were busy. Further on the river beach, two of the three submarines had been dismantled, and countless pieces of steel had been dismantled. Being loaded onto a truck and transported away.

 This is where Qin Tao has lived since he was a child. She and she are almost completely in two different worlds! Perhaps, he was embarrassed to contact me because of the big gap, right? Maybe he wants to wait until the shipyard develops and he has enough status before looking for his own?

Zhao Ling looked at Qin Tao's back again. The dissatisfaction caused by Qin Tao's lack of contact had completely disappeared.

In the canteen, although the tables were a little worn, they were wiped clean without any oil stains. Several plates of dishes were put out, including meat and vegetables.

“What would you guys like to drink?” Qin Tao asked with a smile.

Dad was on a business trip these days, and Qin Tao took the initiative to take on the task of receiving military representatives. Anyway, Qin Tao was so versatile that it was easy to do such a thing.

"No need, as long as there is water. When the missile boat is delivered, we will have a celebration bar then!" Meng Fansheng said.

“Okay, let’s get some bottles of soda, Shiyu, help bring a few bottles over.”

"OK."

  Nie Shiyu left jumping up and down.

“Shiyu, this name is very good.” Zhao Ling looked at Qin Tao: “It sounds much better than your name.”

“Yes.” Qin Tao nodded in agreement.

“Gong Qin, we have brought over the blueprints of the missile boat. Shall we start construction tomorrow?” Meng Fansheng was a workaholic, so this brought up work matters.

“Of course, our shipyard is large enough. It will be no problem to start construction of the first two missile boats at the same time.” Qin Tao said.

 A missile boat of several hundred tons is naturally a piece of cake.

"We have seen the design drawings. The overall design is good, but there is one thing." Meng Fansheng continued: "Wrapping the entire superstructure will require covering a large number of steel plates. Will the overall center of gravity increase? "

Military representatives must also understand technology. Meng Fansheng's words made Qin Tao admire him very much. He really thought about it seriously.

 In the past, there was no such design scheme in China or even in the world. The upper equipment of the warship was exposed to the outside. What was needed was put on it. Although it looked messy, it was nothing.

 Now, everything is wrapped inside, which is equivalent to an extra layer of weight on the outside! As a result, the weight has increased a lot compared to the naked body.

"The catamaran that has been launched currently uses ultra-high-strength steel plates. It has been inspected by the customs and the performance of the hull is very good. Therefore, the lower part of the hull remains unchanged, and the part covered by the upper layer is planned to be used The thinnest steel plate only needs to meet the coverage requirements. Of course, if the Navy requires further reduction of the weight of the upper layer, we can also choose aluminum alloy."

Anyway, the Mingzhou Steel Plant can produce steel plates. Just let them roll a batch of thin steel plates. If the Navy is not satisfied, then use aluminum alloy.

 In fact, the best thing is composite materials. Using composite materials to make warships has the best stealth, after all, it can also absorb part of it.

But now, we have just entered the 1990s, and there is not enough research on composite materials in China. The shipyards are even unable to master the manufacturing technology suitable for the materials, and accidents may occur. Therefore, Qin Tao did not mention it. .

"Aluminum alloy?" Meng Fansheng said: "This is a good choice, but if aluminum alloy is used as the upper covering, how can it be welded to the hull below?"

In the Battle of the Falklands in the 1980s, the British HMS Sherfield caught fire after being hit, burning with black smoke. The scene was extremely spectacular. The fire was eventually unable to be controlled, and damage control had to be abandoned. The reason was later analyzed. Sherfield In order to reduce weight, the superstructure is made of aluminum alloy materials. One reason is that aluminum alloy burns too easily.

However, the experience at that time was not taken seriously by warship designers. After entering the 1990s, aluminum alloys were still used in the construction of various warships, even big ones like the American Littoral Combat Ship. After all, Aluminum alloys were the best material they could find to reduce weight.

 Many missile boats are also made of aluminum.
