Chapter 28 We will have something better!

Chang Haonan's experiment continued until dawn.

The previous simulation and experimental results are exactly the same in terms of rules, which proves that his direction is correct, but the calculation accuracy under specific circumstances still needs to be improved.

The best version has an efficiency increase of more than 25% compared to the original design, and the noise is reduced by an astonishing 10 decibels.

Don’t underestimate this number. Decibels are not a linear value. A decrease of 10 decibels is basically equivalent to a drop to half of the original value in the perception of the human ear. This is already an exaggerated improvement.

When doing testing in a semi-anechoic chamber, he could almost only hear the sound of the motor.

"call--"

Chang Haonan straightened his aching waist, moved his body slightly, and listened to the crackling sound of his joints.

Just now, his attention had been on the experiment, so he didn't feel anything. But now that he relaxed, fatigue swept over his body instantly.

After returning to the dormitory, he fell asleep at the speed of light again after touching the pillow. This has almost become the norm since Chang Haonan was reborn.

Perhaps it can be regarded as one of the benefits brought by the system. After all, he has had insomnia since high school.

When I woke up, it was already afternoon.

After simply washing up, Chang Haonan was going to change his clothes, then find an empty classroom to write out the patent document, and then go to the patent office to submit it.

Just as he was about to go out, he happened to meet a few roommates who pushed in from outside. They must have just returned from lunch.

"Nan Shen, have you read this month's magazine?"

"Magazine?"

Chang Haonan had slept all day long from early this morning to now, so of course it was impossible for him to have any effort.

In fact, from the time he was reborn until now, he went to the library to read the latest news the night he was eating roast duck, and then he has been busy with design work.

"It says that our navy may need to buy two new destroyers." Liang Hao said, stuffing a magazine in his hand over: "

At this time, Chang Haonan also came to his senses. It should be about the two modern-class destroyers.

"If we can really buy these two ships, we will at least have a way to deal with the aircraft carrier." Liang Hao was obviously very excited about this.

"What use are two broken ships from the Soviet era? The missiles above have a range of just over 100 kilometers. They have to be sunk without even being able to see the shadow of the aircraft carrier."

Huang Zhiqiang glanced at Chang Haonan next to him, and climbed into bed with a nonchalant expression: "Besides, the American Arleigh Burke has served sixteen ships. Have you heard of Aegis? It can stop any aircraft or missile, if you ask me. , don’t dream about dealing with other people’s aircraft carriers.”

The inappropriate cynicism made the atmosphere in the dormitory awkward.

After this period of contact, Chang Haonan has roughly recalled that this Huang Zhiqiang is a standard exquisite person according to later generations, but it was rarely particularly obvious in the past.

I may have been stimulated by him recently, so I became a little bit jumpy.

"You really don't need to be too excited about this." Chang Haonan smiled nonchalantly and returned the magazine to Liang Hao.

He never took the other party seriously from the beginning, and there were quite a few such people even after more than twenty years.

"Huh? I thought you should be the happiest one."

Liang Hao was obviously a little surprised by Chang Haonan's reaction.

"Let's see, in a few years we will have something better."

After Chang Haonan finished speaking, he left the dormitory directly with the schoolbag containing the computer on his back.

……

The review of utility model patents generally takes 6-9 months, so Chang Haonan naturally cannot wait for the results to come out before giving out the plan.

Fortunately, patents are calculated based on the filing date, so just make sure to submit it earlier than others.

If this is a formal horizontal topic, then the ownership of this patent should actually belong to the investor.

But then again, setting up a horizontal topic cannot be as simple as five thousand yuan.

In short, after spending two days visiting the patent office and passing the final exams of the two elective courses, Chang Haonan finally contacted Wu Yifan through the pager.

Considering that the house the other party rented off campus was still some distance from the school, after hesitating for a moment, he inserted the phone card back, opened the notebook he carried with him, and dialed his home number.

"Hey?"

When he heard his father's voice again, his mood was much calmer than last time.

"Hey, Dad, it's me."

"...Yes, it's exam week, but there are no important exams this semester."

"...You are talking about the aircraft design course. There is no final exam in that course. There is a course design, which is the course I mentioned before about designing fighter jets."

"...Hey, of course it's been designed, and they don't care whose son I am."

"...It's like this. Because of the course design, there is now an academician of our college, who is the former member of the academic department. He thinks that I have good potential and wants me to join the research group in advance to participate in research, so I probably won't go back during the summer vacation. Next time I should go back during the Spring Festival next year.”

"Money is fine... I still have some money, so don't worry. I should have a scholarship in the second half of the year, don't worry."

"By the way, Jia Yao told me before that she wants to participate in the recruitment next year. Has she told you about this... Oh, what is dad's idea..."

"Well, I also think that Yaoyao's intention should be respected, but the prerequisite is that she has thought about it herself and will not regret it after making the decision..."

"..."

"That's it for now. No more chatting. One of my classmates came to see me..."

Chang Haonan hung up the phone, closed his eyes and took a deep breath, then pulled out the IC card and opened the phone booth door.

Wu Yifan was already waiting outside.

"Nan Shen, you are really awesome. I originally thought that one week was an exaggeration, but it turned out to be less than four days..."

"That's right, no matter who we are..." Chang Haonan said, taking off his schoolbag and handing it to the other party: "The final design plan is in two floppy disks, and I wrote labels on them respectively."

"Okay, but Nan Shen, the final payment may have to wait for a while. The contract states that it must be settled after they win the bid." Wu Yifan was a little worried that Chang Haonan was thinking too much about money: "But if you need money urgently, If so, I can also advance part of it to you."

Brothers have to settle accounts clearly. Although the two of them usually have a good relationship, they still need to be clear about matters involving money.

"No, how can I still not trust you?" Chang Haonan punched Wu Yifan on the shoulder and said with a smile.

In his previous life, Wu Yifan had made hundreds of millions of dollars, and he did not deny that they, old classmates with little money in their pockets, could still be trusted in terms of their character.

Moreover, judging from the fact that he can easily buy a new second-hand laptop from Jiujiu, he won't think much about these few thousand dollars.

After handing the things to Wu Yifan, Chang Haonan took another look at his system.

Since the fan has not had any impact yet, the research points remain unchanged.

But [Engineering Experience] became 60/1000, an increase of 40 points!
