After deciding what to do, Ye Qiu stood up with a bang. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

"What are you anxious about, aren't you looking for trouble when you go on a long leave now? Besides, it's going to be summer vacation soon, and the matter of asking for leave will be put on hold until the beginning of the next semester, anyway, it's a two-month long vacation, and you can go out for a walk if you want to. Nan Xiaonan flew a huge sanitary eye before he could sit down again.

Yes, I'm a little dizzy this time, my sister is about to take the college entrance examination, and it's a long vacation.

There is also Fang Wenrui's throat, which has been off for a week after just a few days of treatment, even if she is in a bad mood, she must be completely cured before going out.

Since Ye Qiu Dou Wei came back from the sea, the relationship between the three of them has entered a delicate stage, which is completely different from the image of the active and profligate wreckage at sea, Dou Wei doesn't even talk to him much if he has nothing to do, although he talks about it with Nan Xiaonan, but Nan Xiaonan can't say anything about the breakthrough of the relationship between the two, and the active contact with him only stays on company affairs, and then Ye Qiu calls her to deal with other things.

Ye Qiu originally had no scruples about talking to Nan Xiaonan, but now he has become less talkative, on the surface, the top management of Datang is the same as usual, but Ye Qiu is also worried that if it goes on like this, the tacit understanding between the three of them will no longer be there, which is quite unfavorable to the development of the company.

The system task has been issued, and Ye Qiu needs to have his own territory, Ye Qiu said that he is not in a hurry, but every day he looks at the small bottle he collects, he is full of emotion, and with the antique and unknown material ring on his finger, he is even more itchy about the space.

It's more of a question, why does the system need territory, there is a faint answer in my heart, according to the current development trend, if all aspects of maintenance grow again, I am afraid that the contact should belong to the future, even if it is only a 4-level tailor series now, it can already repair spacesuits, deep-sea diving suits, protective clothes in a vacuum and the like, but he has not been able to contact these high-tech things, and it is unlikely that he wants to try them.

Out of consideration for the future, Ye Qiucai made up his mind to draw out Ning Chaoran and let him start the improvement and development of rubber materials, with Ning Chaoran's ability to be systematically strengthened, it should not be a few days before there should be results, coupled with the rapid progress of Datang Technology's various work research, after the summer vacation, I am afraid it will attract another wave of listing peaks.

Dou Wei didn't know the current situation, this was just for Nan Xiaonan, for any other girl, she would not be so polite, but it was really Nan Xiaonan, Nan Xiaonan treated her like her own sister, the relationship with Ye Qiu was a little confused and would ask her, she really couldn't bear to rob Ye Qiu like this.

Looking at the current relationship between the three of them, Dou Wei was also extremely anxious, she really wanted to carry the two of them and throw them together.

The treatment of Ye Qiu can't be dealt with, and the treatment of Teacher Xiao Li is still in the process of precipitation, Sha Bin can't beat him to death with a stick at such a time, then it is likely to be true, but the ministry only criticized, and there was no other news coming, Sha Bin had a way, and he simply let Teacher Xiao Li continue to rest at home.

Ye Qiu gave Wei Xun the lubricant additive he wanted in order to replace the land in the Los Angeles military camp, and at the same time took out an alloy formula, and there was a design plan for the propeller propeller, which took so long for the military to finally work.

The design of the new propeller is completely different from that of the previous ones.

The original propeller is mainly constructed with huge streamlined fan blades, and the researchers of the Artillery Research Institute are not unprecedented, in their feelings, the submarine ship has been developed for so many years, and it should have been tested with various propellers, and it is not easy to complete an innovation, and they are not optimistic about Ye Qiu's design.

However, after getting Ye Qiu's design, everyone was a little confused, the propeller used by Ye Qiu turned out to be a double-layer design with honeycomb pipes.

"No, absolutely not!" Just looking at the drawings, the people of the 131 Institute shook their heads:

"How does a double-layer design deal with noise?"

Noise, for the sea vehicle, is simply the most difficult obstacle to overcome, the propeller agitates the seawater, in order to bring thrust, but once it begins to rotate, the sound is inevitable, and it is still such a double-layer fan blade rotating in the opposite direction of the propeller, the forward and reverse water flow are excited, and the water sound is only bigger and more serious.

Ye Qiu didn't explain much about his own design, such a thing, if he didn't make a sample to test it himself, he wouldn't be able to calculate the effect at all.

In line with the trust in Ye Qiu, the 131 Research Institute solemnly handed over the drawings to the navy, and the designers of the navy almost jumped like thunder after reading it, this is nonsense, isn't it good to do your artillery research? Such a design wants to participate in the construction of our Navy?

But under the design drawings, chasing a designer's resume, the name is not written, this is not the point, the key is that the 131 Research Institute wrote down the processing of the rocket trajectory and the final experimental data that Ye Qiu gave them last time, and the navy finally suppressed the urge to make a phone call and scold back.

However, the process of building the real thing according to the drawings was quite unsmooth, and the fan blades were one, which was the rule on large ships and submarines, and it was not too difficult.

When it came time to make the outer shell, the Navy had a problem.

The inner wall of Ye Qiu's shell is designed with countless large and small honeycomb pits, which can allow the water to flow smoothly into the shell and flow out smoothly, because the number is too large, the navy has not made accurate data, the propeller has been manufactured, and it is installed in the tail of the new submarine for experiments, and the people of the Navy Design Institute finally found a huge difference, the old propeller is placed in the tail of the submarine, but the new one has a shell and has become a long cylinder, which can basically be placed at will in the lower half of the submarine.

In this way, it is much more convenient to install weapon systems, and the handling of submarines is greatly improved, and there is also a bonus to speed.

With great joy, the submarine entered the water, the engine started, and the gear transmitted energy to the propeller, and the propeller finally started smoothly, but the faces of both the submarine officers and men and all the designers immediately turned black.

What the hell is this propeller, it's a noise generator, are you trying to kill the enemy with noise?

That voice doesn't need ghost sonar at all, you can hear it from afar!
