Chapter 101 How to Lose Weight

Nie Shiyu has already started school, but today is Sunday. She finished her homework at home and came to the shipyard to play. When she heard that a military representative was coming, she came to have a look. Just in time, she heard Qin Tao say that the representative of the general should be invited. Of course I am very happy to come home.

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

   "Wow, bro, this older sister is so beautiful, much prettier than that older sister last time!"

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

   "Which sister was last time?" Zhao Ling had a smile on her face.

   "Sister Cong Ju, the person who came here as a welder consultant originally said that she would come after the new year. Who would have thought that she would never see her again. This sister, the room you live in is the one where Sister Cong Ju lived."

Nie Shiyu behaved very well, because last time she faced Qin Tao and Cong Ju, she didn't perform well enough and ended up having a big oolong. From that incident, she learned a lesson and must not give Brother Tao shame.

   "Sister Cong Ju?"

   "I'm an old craftsman in the shipyard. He's in his thirties, and his children can make soy sauce." Qin Tao quickly explained.

  Zhao Ling glanced at him, a little happy in her heart, why explain this to herself? It means that he is afraid of being misunderstood, and that in his heart, he still has status.

   Could it be that because of his special status, he has a sense of inferiority, so he doesn't come to him? If so, forgive him.

   "Is it settled? 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 find my brother."

   "Qin Gong, so it's your sister."

   "Well. By the way, you just came here today, and I will take you out to have a good meal, and clean up your dust."

   "No, we don't need to make special arrangements for us, just the cafeteria." Meng Fansheng quickly refused.

  Army representatives have a special status. If they are bought by the sugar-coated shells in the factory and lower their standards, there will be accidents. Before coming, the three of them have accepted the leadership's instructing them not to make mistakes in this regard.

   "Okay, let the cafeteria cook some dishes for you."

   There is a certain distance from the dormitory to the cafeteria. Nie Shiyu was bouncing around. Looking at her, Zhao Ling always felt a little strange. The appearance of the two brothers and sisters is not the slightest similar!

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. On the farther river beach, two of the three submarines had been dismantled. Being trucked away.

  Here is the place where Qin Tao lived since he was a child, and she and her are almost completely in two worlds! Perhaps, he was embarrassed to contact him because of the big gap? Maybe he wants to wait until the shipyard develops and he has enough status before going to find himself?

  Zhao Ling looked at Qin Tao's back again, and the dissatisfaction caused by Qin Tao's lack of contact has completely disappeared.

  In the cafeteria, although the tables were a little worn out, they were wiped clean without any oil stains. Several dishes were placed on the table, both meat and vegetables.

   "What would you like to drink?" Qin Tao asked with a smile.

  Dad was on a business trip for the past few days, and Qin Tao took the initiative to take on the task of receiving military representatives. Anyway, Qin Tao is well-versed, so it is very easy to do this kind of thing.

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

   "Okay, let's have a few bottles of soda, Shi Yu, help me get some bottles."

"OK."

  Nie Shiyu went bouncing around.

   "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.

   "Qin Gong, we brought all the blueprints of the missile boat, shall we start construction tomorrow?" Meng Fansheng is a workaholic, so this brings up work matters.

   "Of course, our dock is large enough, and the construction of the first two missile boats will be started at the same time, so there is no problem." Qin Tao said.

  A missile boat of hundreds of tons is naturally a piece of cake.

"We've already seen the design drawings, and it's pretty good overall, except for one thing." Meng Fansheng continued: "Wrapping all the superstructure will require covering a large number of steel plates. Will the overall center of gravity increase? "

  Army representatives also need to understand technology. Qin Tao also admired Meng Fansheng's words, and he really thought about it seriously.

  In the past, there was no such design scheme in China or even in the world. The upper-level equipment of warships was exposed to the outside, and what was needed was placed on it. Although it looked messy, it was nothing.

   Now, everything is wrapped in, which is equivalent to an extra layer of weight on the outside! In this way, the weight has increased a lot compared to the naked body.

"Currently the catamaran that has been launched uses ultra-high-strength steel plates. It has been inspected by the customs. 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, as long as it meets the coverage requirements, of course, if the navy requires further reduction in the weight of the upper layer, we can also choose aluminum alloy.”

  Anyway, the Mingzhou Iron and Steel Works can produce steel plates. Let them roll a batch of thin steel plates. If the Navy is still not satisfied, then they can use aluminum alloys.

  Actually, the best thing is composite materials. Using composite materials to make warships has the best invisibility, after all, it can absorb part of it.

But now, just entering the 1990s, there is not enough research on composite materials in China, and the shipyard is unable to master the manufacturing technology suitable for materials, and accidents may happen, so Qin Tao didn't 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 Falklands naval battle in the 1980s, the British Shelfield caught fire after being hit, burning black smoke billowing, the scene was extremely spectacular, the fire was finally out of control, and the damage control had to be abandoned. The reason was analyzed later, Shelfield No. In order to reduce weight, the superstructure is made of aluminum alloy material, which is one reason, aluminum alloy is too easy to burn.

However, the experience at that time was not valued by warship designers. After entering the 1990s, aluminum alloys were still used in the construction of various warships, and there were even big guys like the Littoral Combat Ships of the United States. After all, Aluminum is the best material they can find for weight reduction.

   Many missile boats are also made of aluminum.
