Supersonic drones, do you think they will be used to deliver express delivery?

Chapter 7 New Turbofan Engine

Z University, at the school gate.

A black business car passed by the school gate at high speed.

"What kind of rich second generation is this?"

"Someone actually drives a commercial vehicle in school? Is this a new trend?"

I've seen a lot of speedsters.

The first time I saw someone driving a commercial vehicle drifting in school.

"You kid really didn't lie to us. If it's a lie, we'll have to settle the score with your father later!"

In the car, Mr. Li, Mr. Chen and Mr. Ding all stared at Lin Yu eagerly.

These three old men, whose combined ages were almost two hundred, actually made Lin Yu feel shuddering.

"Don't worry, I won't dare to lie to anyone, you three old... old people."

I almost said it to the old guy.

Lin Yu was embarrassed.

Mr. Li snorted.

Mr. Chen urged: "Why don't you hurry up?"

Lin Yu smiled bitterly: "Mr. Chen, we are about to take off soon. This is a business car, not my limited edition sports car."

"Come on, come on, we're all here, why are you in a hurry? Bullying the juniors, you are disrespectful."

Mr. Ding crossed his arms with his chest, looking relaxed and natural, unfazed by honor or disgrace.

Lin Yu watched and subconsciously rubbed his arm.

I didn’t know who it was just now, but I grabbed his arm and asked who made the composite metal.

At this age, his hands are so strong!
  The black business car came to a stop near the ninth experimental base.

When the three old men got out of the car and saw the desolate scenery in front of them, they all turned back to look at the bustling campus behind.

"I said, Mr. Lin, you are not going to kidnap the three of us, are you? What the hell is this place?"

"Why don't you show us the genius who created the memory composite metal?"

"I said, you're not trying to trick us three old people on purpose, are you?"

The three old men stared at Lin Yu.

This feeling of oppression... made Lin Yu feel that it was a bit stronger than his father who was stirring up trouble outside.

"The genius you three are looking for is right here. He also made that metal here."

Lin Yu pointed behind him and said casually.

The expressions of the three old men suddenly changed, and their brows wrinkled.

"What is Zhou Rui doing for a living this time? This is how he arranges outstanding students!"

Mr. Ding cursed without hesitation.

Zhou Rui is the current president of Z University.

"I think he lost his mind after becoming the principal!"

Lin Yu just pretended not to hear, and only these three dared to say so.

"Your good student!"

Mr. Ding and Mr. Chen turned to look at the silent Mr. Li.

Mr. Li put his hands behind his back and coughed lightly to hide his embarrassment.

"I haven't contacted him for a long time."

……

Lin Yu led the way. He checked specifically today and found that Chen Mo had no classes today, so he must be at this place.

however……

When he looked at the deserted and empty experimental base, he was completely stunned.

Without turning around, he could feel the three fiery gazes behind him.

"cough."

Lin Yu turned around awkwardly: "I can explain this."

"What about people?"

Mr. Ding narrowed his eyes slightly.

"I remember I saved your dad's number. He and I haven't been in touch for a long time."

Chen Lao pretended to take out his mobile phone.

Lin Yu quickly stopped him when he saw this.

If Mr. Chen and the old man complained that he had tricked them, he would definitely be grounded by the old man when he returned home.

"Mr. Chen, this is an accident. I didn't know he was not here, so I contacted him immediately." Lin Yu quickly took out his mobile phone, complaining about Chen Mo in his heart.

Why did he disappear at this time?

It’s not even meal time!
  "Old Li, what are you doing?"

Just when Lin Yu was about to call Chen Mo, Mr. Ding suddenly shouted.

Lin Yu looked back and saw Mr. Li running forward as fast as flying.

The experimental base where Chen Mo is located was previously used for aircraft construction. The area is almost the size of a basketball court and a half.

Mr. Li, who is in his sixties, actually reached the middle in just ten seconds.

"This old man has good physical fitness!"

Even Lin Yu couldn't help but exclaimed.

"What's this!"

Li Lao's voice was like a bell, and he shouted towards Lin Yu.

What he saw on his finger was a cylindrical object about as tall as a person. The whole body was made of metal, and the outside was wrapped with lines of three colors: red, yellow and blue.

If you just look at the appearance, it is just an ordinary-looking metal body.

But if you look closely at the structure...

"This is a turbofan engine!"

Mr. Ding walked over quickly. Because he walked too fast, he almost tripped over the parts on the ground.

Fortunately, the old man was in good physical condition. He steadied himself and didn't care about what tripped him.

I came to the turbofan engine excitedly.

"It hasn't been formed yet, but the structure should be a turbofan engine, using a three-dimensional viscous turbine design method. Look here..."

Mr. Ding walked around to the other side, and Mr. Chen and Mr. Li quickly followed after hearing this.

"The material of the guide vanes is still different, the curve is stretched more smoothly, and..."

Mr. Ding gently flicked the leaves a few times with his fingers.

"The sound is wrong, the density should be stronger, but the flexibility should be better."

Mr. Li pointed it out directly.

Mr. Chen frowned slightly and looked at it carefully for a long time.

"Have you noticed that the overall shape design, although it resembles a turbofan, is significantly more than twice smaller in size, and the texture of the heat-conducting and heat-dissipating metal used here seems to be different from what we have seen before."

"The shape of the high-pressure turbine has been deliberately reduced, but the number of blades has increased, and as you can see, the blades are nearly twice as thin."

"It's so thin...aren't you afraid of breakage?"

"No, it seems to be a different kind of steel. The luster on this material is different from the past. I just don't know if the hardness and density can handle overloading."

Lin Yu stood not far away, watching blankly.

He couldn't get a word out of what the three old men were studying there.

But he could tell that this thing seemed to be some kind of engine.

"Did Chen Mo design the drone?"

"Even if the size is reduced, the power is also greatly reduced. It is not suitable for use on fifth-generation machines, and it is not needed on fourth-generation machines. Moreover, this thing cannot be used by reducing the size."

Mr. Li shook his head regretfully.

"It's really a bit of a fantasy."

"What if the material of the blades can maintain supersonic flow speeds, and the second and third stage fans are integral blisk structures welded by linear friction welding?"

A different voice spoke.

"What about speed?"

"Mach 1 to Mach 1.5."

"In this case, wouldn't the performance be lower than the current Turbofan 21? Even worse than the Turbofan 17."

"What if it is used for large drones? The load capacity is only 5,000 kilograms, and the take-off weight and design volume do not exceed five tons."

The three old men were stunned when they heard this.

"Supersonic large drone!"

The name appeared in the minds of all three of them at the same time.

Soon, they suddenly came to their senses. It seemed that the person who answered the question just now was not one of the three of them, nor Lin Yu.

So, that person is...

The three old men turned back together.

At the door of Experimental Base No. 9, a young man with a stern face wearing a black windbreaker was carrying two boxes of lunch and looking at them calmly.

There seemed to be a smile in those deep black eyes.
