Chapter 5 J-7 modification plan

"Then what are we going to do?"

Zhou Shuwan watched Chang Haonan turn off the computer with unfinished thoughts. In the past, he always thought that he was quite talented in academics, but today he really saw what it means to be someone who is different from others.

"Then of course I go back to sleep. I have stayed up late for several days. If I don't catch up on sleep, I will die suddenly."

Chang Haonan took out two floppy disks and carefully put them into his school bag. Then he stood up and stretched his muscles: "Old Wu is right. There is still time to design the course. There is no rush in this day or two."

After returning to the dormitory, Chang Haonan took a hurried shower and fell asleep almost as soon as he touched the pillow.

Probably because he hadn't had a good rest for too long. In short, when Chang Haonan woke up, it was already noon the next day.

Almost out of habit, he wanted to go to the bedside to touch his mobile phone to see if there were any WeChat messages. After grabbing it, he realized that he had returned to 1996.

Fortunately, it's a Sunday, so there's no need to worry about class.

"Haonan, what did you do last afternoon? When we came back in the evening, we could hear your snoring from outside the door. You were silent in your sleep for more than two years."

As soon as Chang Haonan sat up from the bed, a voice came from his upper bunk. He raised his head and saw a boy with short haircut holding a book with a cover and reading.

Chang Haonan remembered that his name was Huang Zhiqiang and his grades were very good, but he really had no more specific impression.

"Hey, I have been busy with the course design these days. I must be too tired. I'm really sorry." Chang Haonan said and picked up his washbasin, tooth cup and towel from the shelf next to him.

Unsurprisingly, Wu Yifan was not in the dormitory. He had lived outside most of the time since his sophomore year.

"Course design?" Huang Zhiqiang put down the book in his hand and looked at Chang Haonan below: "Do you really want you two undergraduates to design a fighter jet?"

As one of the top students in the class, Huang Zhiqiang is well aware of the difficulty of designing a supersonic aircraft, and he also knows Chang Haonan who lives in his lower bunk very well.

The opponent cannot be considered a talented player, not to mention that there are two losers in the course group, Wu Yifan and Zhang Man. Only two people can actually play a role.

"It's enough, it's not too complicated." Chang Haonan was thinking about which improvement plan to choose at this time, so he just waved his hand and answered casually.

After saying that, he trotted away from the dormitory, leaving Huang Zhiqiang with a stunned expression looking at his back as he disappeared through the door.

"It's really crazy..." Huang Zhiqiang shook his head and picked up the book again to study.

"Zhiqiang, you said...he can't really design it, can he?"

Liu Ran, who was also reading a book on the opposite bunk, asked.

"Tch, just them?"

Huang Zhiqiang sneered, looked around to make sure there was no one else in the dormitory, and then continued: "You see, so many members of the academic department and academicians can only copy homework according to the shabby designs designed by the Soviets, if you ask me. , they are all trash, not to mention a few of them."

After finishing speaking, Huang Zhiqiang paused and turned the book over to show it to the other person.

The content inside is actually all in English.

"I asked my sister to mail me an aircraft design manual from the United States. There are many things in it that are not in our textbooks, and the teacher never taught them in class. Are you still designing an aircraft?" Huang Zhiqiang said with a look of disdain. expression.

He originally wanted to go abroad after graduating from his bachelor's degree, but Beijing Airlines' government-sponsored undergraduate study abroad quotas are not available every year, so he had to settle for a postgraduate degree in China first. After graduating from his master's degree, there will be more quotas to study abroad for a doctoral degree. Quite a few.

Of course, the premise is that he cannot participate in confidential projects during his master's degree.

"It seems it has to be you, Brother Qiang." Liu Ran was relieved when he heard what he said and quickly gave Huang Zhiqiang a thumbs up.

The dormitory soon became calm again.

However, even though Huang Zhiqiang said this, Chang Haonan's calm tone and actions just now lingered in his mind, making him unable to concentrate.

"Do they have any other trump cards that I don't know about?" Huang Zhiqiang frowned slightly and thought in his heart.

On the other side, after washing up as quickly as possible, Chang Haonan changed his clothes and prepared to go to the cafeteria for lunch before going to the classroom to meet the other three people.

After all, the course design assignments included a lot of writing, drawing, and simple calculations, which he couldn't handle on his own, and the extra three hours of computer time were crucial.

When Chang Haonan arrived at the classroom where they had agreed to arrive, Wu Yifan and Zhou Shuwan were already waiting inside. However, the three of them waited for another ten minutes and did not see Zhang Man until the agreed time passed. shadow.

At this time, everyone didn't have mobile phones, so there was no way to contact Zhang Man, and there were no short videos in Moments to view, so they could only sit and wait.

"Speaking of which, Haonan, the software you used yesterday was called fluent?" Wu Yifan, who had been stunned just now, suddenly asked.

"Yes." Chang Haonan nodded: "You should at least listen to it in class. Although we have never learned this software, we should have been introduced to it before."

"Ah? Is that so?" Wu Yifan's expression was a little confused.

"No, I remember that computer simulation software was introduced in the design methodology course in my senior year. I had seen it in the senior's book before." Zhou Shuwan also turned around and joined the topic: "Hao Hao Nan, you’re afraid you didn’t think we had learned it all when you were studying on your own, right?”

Chang Haonan rubbed the back of his head in embarrassment. He only roughly remembered that he had been exposed to fluent software during his undergraduate days, but he had completely forgotten how old he was.

"Sorry, sorry, I'm late. I just went to the library to look for some information and didn't pay attention to the time."

At this moment, Zhang Man, carrying a schoolbag on his back and a huge cloth bag in his hand, finally appeared at the door, panting.

Chang Haonan curled his lips. He never liked people who had no sense of time, but he didn't say much: "Now that we are all here, let's get ready to start the next step."

"Well, regarding the improvement plan for this aircraft, I have found some design plans that can be used as a reference. I wonder if Brother Nan is interested in hearing about it."

"what?"

Chang Haonan really didn't expect this to happen. It seemed that the other party's lateness was not entirely due to personal factors.

"Since Brother Nan has analyzed the performance of the MiG-21 prototype yesterday, our next step should be to determine the general direction of improvement, right? Brother Nan?" Zhang Man raised his head again and faced Chang Hao Nan blinked.

"Yes, that's right." Chang Haonan was completely unmoved and just nodded.

"The J-21, a copycat model of the MiG-7, is the main fighter aircraft that our country's aviation industry department can provide to the Air Force in large quantities now, and even in the future, but in any case, it has been almost 40 years since the prototype was put into service. So my idea is to use existing mature technologies to increase the combat effectiveness of the improved model as much as possible within the capabilities of the aviation department."

Having said this, Chang Haonan lowered his head and looked at the enamel water glass he had on hand, took a deep breath and continued: "The feeling of powerlessness we had when we faced the Nimitz and Independence at the beginning of this year cannot be repeated again. ”

Even before his rebirth, even though many years had passed, Chang Haonan still remembered the anger and powerlessness he felt when he saw the news.
