Great warships

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 sister is so beautiful, much prettier than the one from 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 I have never seen 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 Congju?"

"It's a master craftsman in the shipyard. He's in his 30s, and his kids 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. I'll take you out to have a good meal, and cleanse you up."

"No, you don't need to do something special for us, just the cafeteria." Meng Fansheng quickly refused.

The military representative has a special status. If they are bought by the sugar-coated shells in the factory and lower the standard, then there will be accidents. Before coming, the three of them have accepted the earnest teachings of the leaders not to make mistakes in this regard.

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

There was a distance from the dormitory to the cafeteria, and Nie Shiyu was bouncing around. Looking at her, Zhao Ling always felt a little strange. The appearance of the two brothers and sisters was 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.

This is the place where Qin Tao lived since he was a child, and it is almost completely different from her!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 bit 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.

These few days when his father was on a business trip, Qin Tao took the initiative to take on the task of receiving the 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 get 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 building tomorrow?" Meng Fansheng is a workaholic, so this brings up work matters.

"Of course, our shipyard is big enough, and the construction of the first two missile boats can be started simultaneously," Qin Tao said.

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

"We've already seen the design drawings, and the whole thing is pretty good, 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 were all 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, just ask them to roll a batch of thin steel plates. If the navy is not satisfied, then they can use aluminum alloys.

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

But now, just entering the 90s, domestic research on composite materials is not enough, and the shipyard is unable to master the manufacturing technology suitable for materials, and accidents might 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 80s, 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 analyzed later was that the Shelfield was for One reason is to reduce weight and use aluminum alloy materials to make the superstructure. Aluminum alloy is too easy to burn.

However, the experience at that time was not valued by warship designers. After entering the 90s, aluminum alloys were still used in the construction of various warships, and there were even big guys like the US Littoral Combat Ships. After all, aluminum alloys It's the best material they can find for weight loss.

Many missile boats are also made of aluminum.
