Siheyuan: Heavy Industry Revitalizes the Country

"Then does our country have a demand for high-altitude, high-speed interceptors now?"

Fang Xiang also felt that choosing the appearance of this F16 was a bit hasty.

I am a little hesitant, should I copy out the mig31?

"Of course it is needed. The J-8 is a high-altitude, high-speed interceptor.

It is also a new fighter jet designed in response to the current situation and national needs.

At present, our country’s basic national policy is defense-oriented.

Therefore, there is an extraordinary demand for high-altitude, high-speed interceptors.

The multi-purpose fighter you drew is an offensive type...

You understand what I mean, right?"

Professor Li put down the drawing and looked up at Fang Xiang.

"I see. As for the high-altitude, high-speed interceptor, I have some ideas. How about I try to draw a picture?"

Fang Xiang paused and pursed his lips.

The technical difficulty of mig31 is more than one level higher than that of mig25.

The first thing to be faced is the large area of ​​titanium alloy fuselage, which is a threshold that is difficult to overcome in China at present.

However, Fang Xiang has come to terms with it now. The MIG-31 is advanced in all aspects.

What if the indicators are reduced to a level currently acceptable in China according to the design of f16 and mig31?

Does that mean it will become a smaller f16 and a smaller mig31?

At worst, as domestic technology and materials improve, we can gradually upgrade the engine and internal electronic equipment.

Of course, he didn't dare to say such things too confidently.

“It’s a good thing to have ideas. I think the picture you drew this time is very good.

Apart from anything else, at least from the perspective of aerodynamics, I have never seen anyone in China who has better ideas than you."

Professor Li nodded and approved Fang Xiang's drawings.

“As for the internal structure and the whole machine drawings, if you feel you are capable, you can do it yourself.

Although I think it's amazing that you can draw this appearance.

But I think you are also aware of the technical difficulties and manufacturing difficulties brought about by such a delicate appearance.

Compared with J-7 and J-8, it is much higher.

Therefore, the demonstration is easy and the wind tunnel test is not difficult either.

But it may be difficult to make a prototype, at most we can just make a model. . . "

Professor Li paused here.

Fang Xiang naturally understood the meaning of the words.

But being able to achieve this is already very good.

Even if it was just to make some technical reserves for the country, Fang Xiang felt that it was worth meeting Mr. Zhou during the National Day.

The more I understand the current domestic situation, the more frightened I become, but at the same time, the more excited I become.

Even if we take a step back, the fact that he is bringing out these technologies now is equivalent to preparing for the next ten years.

Get yourself a safety jacket.

“I can do the internal structure and the whole machine myself, but it will take a little longer.

As for the appearance, after the wind tunnel test, if there is any data that needs to be modified and adjusted, please notify me in time.

I can also make corresponding modifications.”

Fang Xiang nodded. Now, he just had to face the challenge head-on.

"So, what do you know about Cheng Fei?"

Professor Li hesitated for a while and finally asked this question.

Ever since Professor Li said he was going to Chengfei and invited Fang Xiang to go with him.

Fang Xiang's reaction was indeed a bit abnormal, and it happened in such a short time during the Chinese New Year.

Just draw this appearance of a new type of aircraft, and if you say there is nothing special inside, other people may not think of it.

But in front of Professor Li, who is already an academician, those little thoughts are as ridiculous as child's play.

"Uh... nothing, I just think it's too far, and it would be a bit of a waste of your talents to go there."

Fang Xiang paused for a moment, and was surprised by what Professor Li noticed was unreasonable.

He had thought about it, but Professor Li discovered it so quickly.

Moreover, he asked it in front of him.

I had to come up with the excuse I had prepared before.

"You, if you don't want to talk about it, forget it.

Okay, I'll take this drawing.

I heard you’re getting married?”

Professor Li shook his head and did not ask any further questions.

Instead, he brought up Fang Xiang's personal affairs.

"Well, during the Chinese New Year, I discussed it with my boyfriend's family, probably in May or June..."

Fang Xiang was surprised. He didn't expect that Professor Li knew about his own affairs.

But this is not a bad thing, there is nothing to hide.

Since you asked, just tell me.

"Okay, I understand...

If I have time, I will give you a great gift."

Professor Li suddenly smiled and said something that left Fang Xiang confused.

"That's it, go get busy. I have a lot of things to do here, so I won't entertain you."

Before Fang Xiang could react, Professor Li waved his hand and started to chase people away.

"Uh......"

Fang Xiang felt helpless. How could this be possible? He left the conversation unsaid and still kept people in suspense.

This Professor Li is really...

As for the great gift that Professor Li mentioned, Fang Xiang couldn't think of what it would be for a while.

Maybe, it refers to what gift to give when you get married?

Fang Xiang shook his head and left Professor Li's office.

After getting on the jeep, we returned to the Liu family compound.

Yes, since the beginning of the year, Liu Shuying no longer allowed Fang Xiang to live alone in that small courtyard.

But it was based on the promise that Fang Xiang made last year that he would live here this year.

Let him live in Liu's house temporarily.

As soon as I returned to Liu's house, I found that Liu's father was also at home, talking to Liu's mother, while Liu Shuying was curled up on the side, peeling oranges and eating them like a little squirrel.

"Uncle Liu, Aunt Liu."

Fang wanted to take off his coat and say hello to Liu's father.

"Xiao Fang, please don't mind if we keep this simple at this wedding."

After Fang Xiang sat down on the sofa, Father Liu took the initiative to speak.

"Look at what you said, the current situation is changing rapidly, so it is natural to keep a low profile.

I was thinking that if Luoyi wasn’t too far away, I would have taken Shuying to Luoyi.”

Fang Xiang smiled and picked up the thermos, refilling the teacup in front of Liu's father with water.

"It's definitely not possible to go to Luoyi, it's too far and the conditions are too harsh.

But you, why don’t you think of a way to transfer Xiao Fang back... "

Mother Liu started complaining again.

I don't know how many times I have said similar things during the Chinese New Year.

Mother Liu already knew very well what Fang wanted to do in Luoyi.

Saying more is nothing more than expressing one's attitude.

“Well, spring is coming soon, and all the work needs to start moving forward.

When you are in Luoyi, you can work with peace of mind.

I'll let Qiwen remind you in May.

You don't have to worry about the things in the capital, I will take care of it."

Father Liu patted Mother Liu's leg gently, then turned around and wanted to give her some instructions.

"Okay, I won't say any more. I have something else to do. I'll leave first."

After Mr. Liu finished speaking, he stood up, walked to the clothes rack, put on his coat, and went out.

"Can I take a few days off?"

Liu Shuying, who had just been hiding aside and acting invisible, was now looking at Fang Xiang eagerly, somewhat reluctant to leave.

"Hey, Xiao Fang has been at home for so long.

Men should focus on their careers, so don't hold Xiao Fang back."

As soon as Mr. Liu left, Mrs. Liu immediately changed her attitude. She took Liu Shuying's hand and comforted her.

"I'm a little reluctant..."

However, Liu Shuying broke free from Liu's mother's hand and moved to Fang Xiang's side.

Just like Xiao Fanfan’s favorite thing to do, he threw himself into Fang Xiang’s arms.

"Oh, I came back in May, time flies.

Besides, I can still make phone calls and write letters now, and I don’t have to go abroad.”

Fang Xiang smiled somewhat awkwardly, after all, Mother Liu was sitting next to him.

He could only stretch out one hand and gently pat Liu Shuying's back.

"You guys chat, I'm going back to my room."

Mother Liu had an understanding look on her face, smiled and said something, then went upstairs.

"Oh, I'm going to die!"

Liu Shuying finally reacted, and her little face turned red.

After saying this, she immediately buried herself in Fang Xiang's arms.
