Black technology: I have a refitting factory

Chapter 47 is done, the result of the modification is basically finalized.
Air exhibition 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 show 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 the money was dropped off, a man wearing a white safety helmet and blue overalls walked over in the direction of the money.

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

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

Qian Qian pointed the camera at Yan Zhaowei.

These were agreed upon in advance. The China Southern Airlines Research Institute has the intention to advertise this air show.

"Hello everyone!"

Yan Zhaowei nodded toward the camera.

"Gong Yan, this time I am here not only to deliver the aircraft. On the other hand, I want to understand the entire process of aircraft design, manufacturing, and research and development. The water friends in the live broadcast room are very concerned about these. Can you give me some advice? Shall we introduce these things?"

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

These were not questions he asked on the spur of the moment. As a host, he naturally knew what water friends were concerned about.

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

"Haha, of course there is no problem with this. The development of a new aircraft requires many procedures. The first one is to formulate technical requirements, such as what standards the aircraft hopes to meet..."

Yan Zhaowei took the conversation and started chatting,
"The next step is to design the aircraft. This process is divided into two steps, one is power design, and the other is appearance 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.

But this wing still has shortcomings. When the flying speed is not high, it is a shortcoming. The lift is very reduced and the fuel consumption is high.Small aircraft like this generally do 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 at the engine that had been unloaded on the ground on the other side, and said, "However, if your engine is this size, it should be difficult to achieve this thrust."

He had said it tactfully.

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 produce 1500kw, which can barely reach the speed required by the wing.

But it was the best engine.

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 to say, a little knowledge.

Or, simply copy the blueprints from somewhere.

But if it can be made and the workmanship looks good, it already belongs to a modification factory and is very good.

"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 did not continue, but the expression on his face showed what he meant.

Then he seemed to remember something and asked, "How much did you spend on this?"

"133w."

Money grinned.

Yan Zhaowei: "..."

This was the first time he saw someone who had lost so much money and could still smile 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.Teacher Jin, I also graduated from Harvard before. "

"Teacher Jin graduated from Harvard?"

Hearing Qian Qian chatting with the live broadcast room, Yan Zhaowei was taken aback. He didn't expect that the live broadcast industry is 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 live broadcasting the assembly of the aircraft, Qian Qian originally wanted to live broadcast the test flight, but due to air traffic control today, the aircraft could not fly without applying in advance.

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

"Finally I can relax."

Qian got into the taxi and relaxed all over.

Judging from the current situation, the hole dug previously has basically been buried.As long as the air show is broadcast live tomorrow, the matter of this modification factory will be over.

"If you are happy in life, you must have all the fun. Don't let the golden cup stand empty against the moon. In the evening, you must make an appointment with two beauties, pair it with steak, and open a bottle 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!
