Chapter 172 The most important weapon of the country

"Do you know anything about engines?"

Faced with this question, Fang Xiang was suddenly stunned.

This... Is Mr. Huang serious?

“I know a little bit…”

In order to avoid being considered young and frivolous, Fang Xiang was a little humble.

"Know a little bit? What do you know a little bit about? Tell me."

Old Huang chuckled. This young man was praised to the utmost by him.

I saw him today, and I am determined to pass the exam.

I originally thought that it was just hype and I somewhat underestimated it.

However, Fang Xiang's humble attitude did make Mr. Huang more favorable towards him.

“I know a little bit about gasoline engines, diesel engines, aerospace engines, and aviation engines.”

At this moment, Fang Xiang also noticed the scrutiny in Mr. Huang's eyes.

But if I understood, I would just say it out loud.

"Oh? You know a little bit about this across such a large area?"

Mr. Huang laughed. He was so young, yet he knew everything. Are you really not here to tease me?

Mr. Huang's impression of Fang Xiang basically came from some compliments he heard over the phone.

What the future of the country, young genius, top designer in the country.

As a senior researcher.

Mr. Huang knows best that technology requires time to accumulate.

According to what was said on the phone, could it be that Fang was born with this knowledge?

So, naturally, he didn't believe it. He only believed his own eyes.

“I have designed engines for Dongfanghong tractors, Jiefang trucks, Hongqi sedans, jeeps, and heavy trucks.

He also participated in the design of WP-6 and WP-7.

I think you have a rough understanding of it, right?!"

Fang Xiang looked at the expression in Huang Lao's eyes, which changed from curiosity to scrutiny, then to doubt, and now to contempt.

I know that older people are more or less stubborn, or they stick to their own ideas.

Just bring out your resume.

"You worked on WP-6 and WP-7?"

When Mr. Huang first heard the names of the engines, the contempt in his eyes did not change at all.

But when he heard the words WP-6 and WP-7, his expression finally changed.

"Yes, I drew some pictures."

Fang Xiang nodded. Since he had drawn the picture, he was considered to have participated. There was nothing wrong with that.

"Then tell me the difference between a turbojet and a turbofan."

When Mr. Huang heard this, he became happy again and planned to test him further.

"A turbofan engine is based on a turbojet engine, with a turbine added to drive the fan and compressor.

Thermal efficiency is reduced, but thrust is greater.”

Fang Xiang felt a little helpless at this time, as if he was back to the situation he encountered when he first went to the Ministry of First Machine Building.

However, Mr. Huang is so old, and he is still an academician. No matter what, he should be given the respect he deserves.

So he answered honestly.

"Then do you know the difference between a rocket engine and an aircraft engine?"

Mr. Huang nodded and raised the question to a higher level.

"A rocket engine is a jet engine that has its own oxidizer and is structurally simpler than an aircraft engine."

Fang Xiang rolled his eyes. This is a question that all freshmen know, right?

"Then do you know the difficulty of rocket engines?"

Mr. Huang raised another question.

“Materials, temperatures, assembly processes, design complexity, precision control, and stability.

Mr. Huang, why don’t you take me to see the engine that is currently being developed so I can see where the problem is.

My time is also time."

Fang felt helpless. Mr. Huang was not a teacher. He asked me these basic questions. Was it useful?

There is no meaning other than adding more words.

Just ask directly to see the engine.

"Okay! Anyway, your confidentiality level is high enough.

I'll take you to open your eyes.

Don't think that just because you have learned a little, you can show off your sword skills in front of Guan Gong."

Mr. Huang also smiled and pointed at Fang Xiang.

He immediately stood up and took Fang Xiang to the experimental site for a look.

"My boy, you are still young, and there are many things that you cannot understand just by reading books or listening to others talk about them.

The world is big, full of unknown areas and amazing wonders.

Just like the boundless blue sky we can see and those white clouds in various shapes and sizes, each one has a different story and meaning.

There are also tropical rainforests and polar glaciers. From deep-sea reefs to high-altitude clouds, every place contains the wisdom and power of nature.

But this is only on Earth. Have you ever seen space?

Do you know how many secrets are hidden in space? "

Mr. Huang talked as he walked.

To Fang Xiang, he sounded a little nagging, but he meant well.

She didn't interrupt him, nor was she boring enough to say that she had seen much more before she crossed over here.

After going downstairs, the huge cave is not far away.

From a distance, I thought it was only three stories high.

But when I really got up to it, I found that there were at least five floors.

Looking at the stones at the edge of the cave, Fang Xiang found it hard to imagine how, in this era, such a large hole could be dug out in the mountain with just an axe and a chisel.

But he knew the southwest and northwest at this time.

There are many more places like this.

The guard soldier saluted as he crossed the doorway, and his vision gradually darkened.

There was only a faint light hanging in the cave, and lines could be vaguely seen.

There are railroad tracks underfoot, but no rail cars are visible.

Looking up into the depths, a hundred meters away, there was a huge rocket standing in the dim light.

Next to the rocket, there were many people in white clothes, busy at work.

Along the walls, there were many iron boxes with wires wrapped around them, flashing red, yellow, green, blue and white lights.

The further you go inside, the higher the temperature.

Soon, he arrived in front of the rocket.

When I looked up, I realized that the top was not a mountain.

But it is a huge iron plate.

Could it be?

Fang Xiang glanced around.

In the dim light, I could see the mechanical device.

I estimated the distance from the ground to the top, it was more than thirty meters.

It went around the rocket, with a robotic arm supporting the rocket from the side.

It can be seen that the base of the rocket is the rail car.

Many staff members around looked at Fang Xiang with curious eyes.

But it was just a look, everyone was busy with their own work.

“This is a medium-range ballistic missile that can be launched from a mobile launch system and uses a single-stage liquid-fuel engine.

The design range is 3000 kilometers, and the purpose is to be able to carry Miss Qiu, who can be miniaturized in the future.”

Mr. Huang stepped forward and stroked the unpainted missile.

"This is the Dongfeng-2500, the initial version of the medium-range ballistic missile, with a range of kilometers.

The take-off weight is 64 tons and the warhead payload is 2.15 tons.

24 meters long and meters in diameter.

It can carry one high-yield warhead or three low-yield warheads.

Hit accuracy 3000 meters."

Fang Xiang looked at the unfinished missile and silently recited its parameters in his mind.

Later, it was she who sold it to the camel.

It has intimidated the Middle East for thirty years and forced Shadamu to retreat outside the country.

Even the beautiful country is helpless.

The most important weapon of the country!
