The military-industrial scientific research system of the academic master.

"This is..." Liu Hongbo took the book and glanced at it twice. The expression on his face quickly turned to shock. After turning back a few pages, it turned to anger again.

There is a "Design Calculation Example" chapter at the end of this book. The design process of a small seaplane is almost exactly the same as that submitted by Huang Zhiqiang!

Although considering the difficulty of this course, Liu Hongbo does not prohibit students from referring to calculation examples in textbooks or other books, but they need to be marked according to the references. Too many reference parts will have a negative impact on the results.

Naturally, there is no label in Huang Zhiqiang’s design description.

Besides, this situation can no longer be called a reference, it is completely plagiarism!

And he actually wanted to give this assignment full marks before!

Liu Hongbo suddenly felt that he had been fooled.

"Forget it, you can handle this matter. I'll go back first." Du Yishan's good mood was completely ruined by this incident. He got up and left Liu Hongbo's office without even taking the book.

A few minutes later, Liu Hongbo picked up the phone receiver on his desk with a gloomy expression.

"Hey, is this Teacher Yan Lu? Please make another trip and ask your classmate Huang Zhiqiang to come to my office."

"It doesn't matter. I'm always in the office. You can wait no matter how late it is."

Although Liu Hongbo had already made a rough guess about the situation, after all, it was related to a student's grades and even his future, so he decided to suppress his anger first and call Huang Zhiqiang over to ask more detailed questions about design ideas.

If the latter can describe a closed-loop thinking process like Chang Haonan did just now, then he can think of it as a coincidence.

But if not, that's a different story.

……

In this era, papers still had to be submitted by hand, so Chang Haonan, who left Du Yishan's office, went directly to the stationery store to buy a stack of manuscript paper, and then went straight to the library.

As for Yan Lu’s bicycle...

It's better to do it later, I believe Sister Lu will understand.

Chang Haonan found a quiet place to sit down, took out the Hero 100 pen that his father gave him when he was in college from his stationery bag, and wrote the title of the paper he had already thought of on the manuscript paper.

"Research on the integrated layout of dual-module mandibular inward-turning inlet/conical anterior body"

Abstract: In order to achieve a good match between the internal contraction flow field of the three-dimensional inward turning inlet and the external compression flow field of the conical precursor, a double-modules mandibular inward turning inlet/conical precursor (Double-modules chin) is proposed. Inward-turning inlet and conical forebody (DCII/CF) integrated design method, a novel DCII/CF integrated layout of juxtaposed inlets is obtained. For this layout form, we carried out...

For handwritten papers, writing is actually very simple. The troublesome part is drawing, which needs to be hand-drawn on graph paper and then pasted on. It is not pasting with Ctrl+V, but with glue and physical pasting.

Fortunately, this is only the first draft, and Wu Yifan has already prepared the required charts before, saving Chang Haonan a lot of effort.

Since he had become very familiar with the contents in the past half month or so, Chang Haonan did not spend much time and only took about four hours to complete it smoothly.

It was already evening at this time, and Chang Haonan estimated that Du Yishan had probably already gotten off work, so he decided to send him there tomorrow.

Looking at the 10 pages of manuscript paper that had been filled in front of him, he stretched contentedly.

"Speaking of which, it's time to contact my family again."

Chang Haonan called home the day after he traveled through time, but at that time he couldn't control his emotions at all, so he only chatted for a few words and hung up in a hurry.

Thinking that after getting used to it for so long, it should be no problem.

Other than that...

He is almost out of money.

Originally, the holiday was coming soon, so I just had to hold on to the remaining money for a few more days and then buy a train ticket to go home.

But this summer vacation, he knew that he would most likely not have time to go home.

So I have to talk to my family about this in advance.

Chang Haonan's father, Chang Yuanchao, is a policeman, and his mother, Zhou Li, is a high school Chinese teacher.

Yes, he was Chang Haonan's Chinese teacher and class teacher in high school.

He was able to get into the Beijing University of Aeronautics and Astronautics, and it was indispensable for Ms. Zhou Li’s double encouragement both mentally and physically.

This kind of family background is supposed to be pretty good, but unfortunately my father has always had the attitude of raising children in poverty and raising daughters in wealth, so even after he went to college, he never had enough money.

After packing all the materials and papers into his schoolbag, Chang Haonan went to the public phone booth again, took out the IC phone card with the Yellow River pattern printed on the surface, and dialed his home phone.

"Hey, is it brother?"

A slightly immature female voice rang on the phone. It was Chang Haonan's younger sister, Chang Jiayao, who will be in her third year of high school in the second half of the year.

"It's me, why are you at home today?"

It's not dinner time yet, so Chang Jiayao shouldn't finish class so early.

"Brother, today is the weekend..."

"..."

Because Teacher Liu Hongbo only borrowed the lecture theater for today, the defense review was forced to be scheduled on Sunday. However, Chang Haonan had experienced too much in the afternoon just past, so he forgot about it.

"Okay, are your parents home?"

"No, I'm working overtime. I'll cook for myself at night." Chang Jiayao replied with a somewhat aggrieved voice.

The police are naturally busy day and night, and high school teachers may not always get a break on weekends. It is normal to be away from home.

"Okay." Chang Haonan's mood was a little complicated, not just because of the issue of living expenses, but because he did have a feeling similar to the shyness of being close to home: "How is Jia Yaoqian's recent studies?"

This is almost a question asked subconsciously, because Chang Haonan, who has returned from rebirth, actually knows his sister's situation. It will definitely be no problem to get into college, but it is basically impossible to get into a school like Beijing Airlines.

"Oh... that's it. If you don't go to college, it will be fine to go to university anyway." Chang Jiayao herself was very open-minded: "But brother, I want to ask you something."

"what's up?"

Although Comrade Chang Yuanchao has always shown a preference for girls over boys, this did not greatly affect the relationship between Chang Haonan and his sister, except that when he was a child, he often cheated his sister of pocket money.

"You studied airplane design in college?"

"Yes, aircraft major." Chang Haonan nodded and quickly searched his memory. He did not recall that his sister had shown any interest in his major.

"Brother, have you ever seen a moving airplane?" Chang Jiayao's tone was a little excited.

"Of course I have."

Chang Haonan's answer came out of his mouth.

But after he said this, he realized that he had probably never seen it before. Beijing Airlines has a famous aircraft museum, but the planes in it are obviously not flyable.

"What about the pilot? Brother, do you know the pilot?"

"I know a few of them." Since they had just said they had met each other, Chang Haonan simply pretended to be the same: "Why, you are already looking for a boyfriend at such a young age?"

"Brother, don't talk nonsense!" Chang Jiayao's voice slapping the table came from the receiver: "I... I want to participate in the Air Force recruitment next year."

Chang Haonan was completely silenced with one sentence.

He didn't remember that his sister had such an incident in the original timeline.
