Siheyuan: Heavy Industry Revitalizes the Country

January 1966, 1, Beijing, cloudy.

"When did you learn pneumatics?"

Professor Li looked at the beautiful appearance on the drawing and wished he could glue his eyes to it.

“This appearance is so beautiful.”

Professor Li didn't seem to mind Fang Xiang's silence and devoted himself to the drawing.

Yes, the one on the drawing is the famous F16 Fighting Falcon.

However, due to time constraints, Fang Xiang only completed a small part of the drawing design work before leaving Beijing.

Only a week has passed since I last boasted to Professor Li.

The New Year of 1966 had passed, and Fang Xiang was ready to return to Luoyi.

However, time is tight and the engine part has just started.

In desperation, Fang Xiang had to give the appearance drawings to Professor Li first.

"Have you ever considered how difficult it would be to manufacture something this beautiful?"

Professor Li has looked through this F16 countless times. It has a very beautiful appearance.

Obviously, Professor Li was greatly shocked.

“You just said that this appearance is very consistent with the principles of aerodynamics.

So what do you think is more important, cost or performance? "

Fang wanted to know that Professor Li was not actually blaming him, but was reminding him implicitly.

The price that the national industry has to pay to build this aircraft is extremely high.

However, Fang Xiang knew very clearly that future wars would all depend on air supremacy.

The design of the F16 will not be outdated even in 2024 when he travels through time.

Moreover, it is the main fighter jet of many countries in the world.

Therefore, if the appearance is finalized, only the internal structure, engine and radar function need to be upgraded accordingly.

This is much more durable than Master 8.

It can even be said that, to a certain extent, it was due to its excellent aerodynamics and the heart that Fang Xiang provided him.

This will allow it to firmly stand between T60 and T0 in the world in the next 1 years.

“Your exterior design is extremely bold and innovative.

Full of imagination.

However, it is useless to have only appearance on paper but cannot realize it. "

Professor Li's eyes were filled with complexity.

“I’m still drawing the internal structure, and I have some ideas about the matching engine.

But these things take time. You know how much manpower, material resources and time are needed to design a complete fighter plane."

Fang Xiang shrugged. This was something he had planned long ago.

As for Luoqi, apart from Daliang, there is nothing else to worry about.

Samples from the Hangzhou Engine Factory were also sent over.

The factory is organizing a test run.

Once Dongfanghong is assembled and there are no major problems with the test run.

So even if Jeep 213 was added, he wouldn't have much to do in the factory.

Staying in the factory is nothing more than acting as a stabilizing force.

With talents like Cao Tianwei around, give him some time.

It is only a matter of time to fully understand Dongfanghong and 213.

"So, you decided to go to Chengfei with me?"

Professor Li's eyes sparkled.

“No, I won’t go to Chengfei.

To be honest, I don’t really recommend you to go to Chengfei.

There are plenty of other people out there who can take your place as the general manager.

But this aircraft was designed, verified, demonstrated and trial-produced.

I don’t think anyone can replace you.”

Fang Xiang was a little amused and shook his head to reject Professor Li's second invitation.

He really didn't expect that Professor Li would think that he had changed his mind just because he designed the airplane?

Moreover, Fang Xiang was indeed not very confident in handing over the complete design and engine drawings of the aircraft to others.

Professor Li was certainly not as nice to him as Professor Xu.

But after all, there is some kind of relationship between master and disciple.

What’s more, Professor Li is an academician!

The resources that can be mobilized and the voice that can be expressed are far greater than those of ordinary people.

"What you said makes sense...

I think that the appearance design alone is more than ten or even twenty years ahead of the world.

Wind tunnel testing is necessary.

Neither you nor I would feel at ease if we leave it to anyone else.

How about this, you don’t have to go to Luoqi, come with me to report to the Chinese Academy of Sciences.

How about being my assistant and moving this project forward together?"

Upon hearing this, Professor Li felt that what Fang Xiang said made sense.

Aviation is a large category and a key link that the country attaches great importance to.

This idea has evolved from firearms to vehicles and now to aircraft.

Has already demonstrated top talent.

This is no longer something that can be explained by a genius.

In Professor Li's eyes, it was a bit of a waste to put it in such a small place as Luoqi.

"Well...

To be honest, going to the Chinese Academy of Sciences has been my long-cherished wish.

But as I said last time, a large group of people will go with me to Luoyi this time.

There was no way I could abandon them and go back to Beijing alone.

At least, you have to wait until I make achievements in Luoyi, right?"

Fang Xiang heard that Professor Li planned to take him to the Chinese Academy of Sciences.

My heart suddenly started beating violently.

It would be a lie to say that I am not moved.

But it’s still the same problem, Liu Qiwen, Cao Tianwei and others.

It was all because of me that I was transferred to Luoyi.

No matter what, I can't justify abandoning them at this time.

I can only say that Professor Li’s proposal came too late.

With no other choice, I could only refuse temporarily.

But in the end, Fang Xiang also expressed that he hoped there would be such an opportunity in the future.

"Well then...

I won't force you.

By the way, which direction did you design this plane to fly?"

The light in Professor Li's eyes gradually dimmed as Fang Xiang refused.

Of course, he also heard that Fang Xiang was quite excited about going to the Chinese Academy of Sciences.

At this time, you can only press.

Let's turn the topic to the plane itself.

"High altitude and high speed... As for whether it's an interceptor or multi-purpose, I haven't decided yet."

Faced with Professor Li's question, Fang Xiang was suddenly startled.

The F16's exterior design is not high-altitude and high-speed.

Instead, it was developed as a multi-purpose fighter.

Even if you equip the F16 with the MIG25 engine, it still won't be able to fly 3-3!

So, as I was talking, this F16 that I drew was a bit impulsive.

"It doesn't look like a high-altitude, high-speed interceptor to me.

Besides, you know that the J-8 is a high-altitude, high-speed interceptor.

You look more like a newer multi-role fighter.

Just now you said that you had some ideas about the engine, what are they, can you tell me about them?"

After all, Professor Li is an academician in the aviation field and a top expert.

He denied what Fang Xiang had just said at a glance, but did not criticize him. Instead, he asked about the engine.

"It can probably have a thrust of 60-80 kilonewtons, and the afterburner can reach about 80-100."

Fang thought of the R-25B-15 engine of the MiG-300. Its parameters were not abnormal.

But the performance in all aspects is almost doubled compared to the current turbojet 7 which has a thrust of less than 60 kilonewtons.

Moreover, the actual strength of the R-15B-300 engine is stronger than the maximum 8 kN of the WP-93.

But think about the domestic industrial strength, and this engine requires a comprehensive multi-functional electronic control system.

I gave a discount unconsciously.

Not to mention, the WP-8 is installed on the Type 6, and it would not work well on a fighter jet with such a small body.

“Well, let’s draw the picture first.

Later, when you come up with the complete design of the fuselage, I will see if the WP-7 can be installed on this aircraft.

If the WP-7 can be installed on this aircraft, I think the J-8 will be at least ten years behind. "

Professor Li no longer has any doubts about Fang Xiang's ability to design engines.

However, in Professor Li's opinion, Fang Xiang is more adept at cutting-edge theoretical research.

Rather than the practical applications that are very important right now, it is somewhat similar to theoretical physics and applied physics.

In fact, Professor Li’s view of the other party is very correct.

This is the path Fang wanted to take, rather than spending countless time, energy and money on cash.

It would be better to implement more advanced technologies in the future more quickly.

"So what is our country's current demand for high-altitude, high-speed interceptors?"

Fang Xiang also agreed with Professor Li’s evaluation and opinions.

The F16 was not designed for high altitude and high speed.

Although his original idea was to take out the mig-25, unfortunately the Soviet Union already had a prototype.

It would be a lot of fun if he designed one exactly the same.

But it doesn't mean that he only knows about the mig-25, which is high-altitude and high-speed, and there is also a mig-31.
