Black technology: I have a refitting factory

Airshow Hall.

Aircraft parked in warehouse.

Three large trucks drove in slowly.

"Water friends, this is the place where the aircraft is parked in the air exhibition hall, and it is also the place where the aircraft is processed and assembled." Qian Qian jumped from the passenger cab of a truck and took a picture of the warehouse with his mobile phone.

"Wait a minute, our planes are also assembled here."

This air show did not involve any confidential things, so he was able to apply for the live broadcast permission.

Shortly after Qianqian got off the car, a man wearing a white helmet and blue overalls walked towards Qianqian.

"Dear friends, let me introduce to you. This is Yan Zhaowei, Yan Gong, a senior engineer of the China Southern Airlines Research Institute. He has been working in the propeller aircraft design industry for nearly 20 years. A very skilled and experienced tall engineer.

He took the lead in assembling all the aircraft in this air show. "

Qian Qian pointed the camera at Yan Zhaowei.

These have been agreed in advance, and the China Southern Airlines Research Institute has the intention of advertising for this air show.

"Hello everyone!"

Yan Zhaowei nodded towards the camera.

"Yan Gong, I'm here this time, besides delivering the plane. On the other hand, I want to know about the whole process of the plane from design, manufacturing, research and development. The water friends in the live broadcast room are very concerned about these. Can you give Shall we introduce these things?"

Qian Qian picked up his mobile phone and showed Yan Zhaowei the bullet screen in the live broadcast room. At this time, the bullet screen was already Yishui's "introduction".

He didn't ask these questions on a whim. As an anchor, he naturally knew what water friends cared about.

So he has already told the China Southern Airlines Research Institute in advance, hoping to talk about this topic.

"Hehe, this is of course no problem. The research and development of a new aircraft needs to go through many procedures. The first step is to formulate technical requirements, such as what kind of standards this aircraft hopes to meet..."

Yan Zhaowei took the conversation and started chatting,

"The next step is the design of the aircraft. This process is divided into two steps, one is power design, and the other is shape design..."

"The most important thing in power design is the engine. In terms of engines, especially turboprop engines, our country still lags behind the top level of foreign countries. In this regard, we are also working hard to catch up..."

"In addition, the shape design, especially the wing design, is also a very important point for an aircraft. There are many types of wings, and each has a different purpose.

For example, the wing in front of me is a modified supercritical wing. "

Yan Zhaowei pointed to the wing being unloaded from the truck, "The design of this wing is to reduce the shock wave when flying at high speed, so as to ensure the smooth operation of the aircraft and reduce fuel consumption.

However, this wing still has disadvantages. When the flying speed is not high, it is a disadvantage. The lift is very reduced, and the fuel consumption is more. Such a small aircraft generally does not use this design. "

"That is, is the wing actually good-looking or not practical?"

Qian Qian asked expectantly.

"Uh... I can't say that. If the speed is high, it should be possible. The main thing is to see if the power driven by the engine can reach this power.

Generally speaking, the power of the engine is related to the size. "

Yan Zhaowei replied, paused, looked to the other side, the engine that had been unloaded on the ground, and said, "However, if your engine is of this size, it should be difficult to achieve this thrust."

He's been very euphemistic.

In fact, he was not optimistic about this aircraft modification at all.

Aircraft wings and aircraft engines must be matched. With the size of the current engine, the best engine can generate 1500kw, which can barely reach the speed required by the wings.

But that's the best engine ever.

He didn't think that a refitting factory could make any powerful engine. At best, where to find an engine that is commonly used in the market. It can only be said that the person who designed this wing did not know much about the overall design of the aircraft.

That is, half-knowledge.

Or, simply copy the blueprints from somewhere.

But if it can be made, and the workmanship looks good, it is already very good in the refitting factory.

"Is that so, then I seem to have been tricked?"

money asked.

"Well, depending on your requirements, if it's good-looking, it shouldn't be considered a scam. The shape of this wing is still very good-looking. If it's performance..."

Yan Zhaowei smiled and didn't continue to speak, but the expression on his face showed what he meant.

Then, as if remembering something, he asked, "How much did you spend on this?"

"133w."

Money grinned.

Yan Zhaowei: "..."

It was the first time he saw that someone who had lost so much money could still laugh so happily.

Money is naturally happy.

According to what Yan Zhaowei said, the result of the modification is basically a conclusion!

If the effect in the contract cannot be achieved, Su Qi will have to pay back the money spent on the modification. At most, he should be more generous. Don't return all of it. Throw away the cost and calculate part of the labor cost.

It should be about 30w in total.

Compared with the gifts from the live broadcast, I still made a lot of money!

"Mr. Jin is really a dog!"

"Why do I feel that this guy, Lao Jin, found a banquet worker in advance, and came back to cheat us of money!"

"The only dream in life is shattered!"

...

There was a lot of complaints in the live broadcast room.

Seeing the barrage, Qian Qian smiled and said, "My friends, is I, Teacher Jin, that kind of person? Contact me in advance, how could I do such a thing?

Mr. Jin, I am extremely confident. I made this judgment based on my excellent knowledge. Mr. Jin, I was also a Harvard graduate. "

"Ms. Jin graduated from Harvard?"

Yan Zhaowei was taken aback when he heard Qian Qian chatting with the live broadcast room. He didn't expect that the live broadcast industry has become so busy now. Even students who graduated from Harvard have gone live.

"Uh, from Harbin Buddhist University."

Qian Qian looked at Yan Zhaowei and squeezed out a smile.

Yan Zhaowei: "..."

Studio:"……"

...

After the live broadcast of the aircraft assembly, Qian Qian originally wanted to broadcast the test flight, but because of the air traffic control today, the aircraft did not apply in advance, but it could not fly.

After a wave of teasing with water friends, after receiving a wave of gifts, Qian Qian shut down the live broadcast.

"It's finally time to relax."

Qian Qian got into the taxi, and his whole body relaxed.

Judging from the current situation, the pits dug before have basically been buried. Just wait until the live broadcast of the air show is over tomorrow, and the matter of the refitting factory will be over.

"To be happy in life is to have a good time, don't let the golden cup be empty to the moon. In the evening, you have to meet two beauties, serve with steak, and open a glass of champagne to celebrate..."

Thanks for the big rewards of onion and cantaloupe, thanks to Qiu Mo, Who Tama for buying millet, ending in 1857, and ending in 3400, for the monthly tickets, and everyone who voted for recommendations to follow up, thank you for your support!
