212: Common things

Xu Ning's writing was fluent and mature, leading Du Yishang to speculate that he must have read a large amount of literature in related fields.

Aside from a few places where sensitive data was deleted or altered, the entire paper required almost no changes.

"He's truly a young man who is both talented and willing to work hard," Du Yishang sighed, "I even feel embarrassed to add my name to the list of authors."

Du Yishang put down his pen, took off his glasses, and rubbed his eyes, lamenting that he was no longer young and that his physical strength and energy were declining year by year.

At the same time, outside the library.

Xu Ning encountered Zhao Zhide, as well as a slightly older-looking man holding a kraft paper folder.

"This is Mr. Hao Dagang, the technical expert I mentioned before, and also the Boss's brother-in-law," Zhao Zhide introduced, "And this is the young man we invited to help solve the problem, Xu Ning."

The two men nodded to each other in greeting.

In this era, "the Boss's brother-in-law" was not yet a label with negative connotations; it more often meant that this person was the Boss's confidant.

"Hello, Team Member Xu," Hao Dagang greeted politely, while handing Xu Ning a folder: "This contains all the information about our fan blades.

If you think you can do it, please consider signing the contract."

Xu Ning found a long bench to sit on and began to carefully study the contents of the file.

"Did you develop this blade shape yourself?" he asked.

Originally expecting to see some common NACA standard blades or casually drawn sketches, he didn't expect the file to contain not only development drawings but also a detailed process of blade development.

Clearly, the company's technical team was well prepared.

"Yes, my brother-in-law and I developed it together.

Although it's better than other domestic brands, it's still not as good as Fuji Electric's products in terms of noise," Hao Dagang said with a slight hint of regret in his tone:

"Because we are launching a completely new air conditioner model, the fan was also newly developed.

On the one hand, we couldn't obtain specific samples from Fuji, and on the other hand, we wanted to remain innovative rather than simply copy others' work."

Xu Ning nodded and commented, "Your mathematical foundation is really good."

Although this kind of development might not seem like the best choice today, for most companies at the time that only knew how to imitate standard models, being able to develop independently was already a significant step forward.

"You flatter me, I'm just a technical secondary school graduate, unlike you who received higher education," Hao Dagang responded humbly.

"Don't say that, the technical secondary school exams back then were also very difficult," Xu Ning continued, "Especially your creativity, using Bezier curves to shape the blades, it's truly unique."

Just as the two were talking, Zhao Zhide, who was standing nearby, seemed to sense that something wasn't quite right.

"Alas, talking so much is useless, after all, we still can't compare to Fuji Electric's technology.

Although I'm unwilling to admit it, we just can't catch up to them on such a small component," Hao Dagang sighed, "I wonder if you can help us improve it?"

As the conversation deepened, Hao Dagang became even more respectful of Xu Ning.

"Bezier curves are widely used in aviation and turbine fields, but they also have limitations," Xu Ning analyzed, "Firstly, adjusting one point affects the whole; secondly, they are not precise enough when dealing with curves like circles, resulting in an uneven blade surface."

Hearing this, Hao Dagang's eyes lit up: "So, you already have a solution?"

Xu Ning nodded affirmatively, then turned to Zhao Zhide and said, "Old Wu, prepare to sign the contract."

Xu Ning was actually a subcontractor, but this was approved by the client.

After Hao Dagang signed the contract, he immediately took out a kraft paper envelope from his bag and handed it to Zhao Zhide.

The envelope contained 1000 RMB in cash, which was not a small amount at the time.

Zhao Zhide checked the amount, quietly took out two hundred-yuan bills and put them in his pocket, then gave the remaining money and the envelope to Xu Ning, thus finalizing the deal.

"The development of optimized blades is entirely up to the two of you.

Our Boss highly values the Changhong Air Conditioner project, and we hope you can give it your all."

Hao Dagang packed up the documents, stood up, and cupped his hands towards the two, showing a bit of a chivalrous demeanor.

After all, in this era, people who dared to carry large amounts of cash for transactions usually had some background.

After Hao Dagang left, Zhao Zhide took off the backpack from his shoulder and handed it to Xu Ning: "Ning Ge, how long will it take?"

"Hard to say, but probably around a week," Xu Ning took the backpack, which contained the laptop and floppy disks he had been using these days.

"A week?" Zhao Zhide was so surprised he almost dropped the backpack, luckily Xu Ning quickly grabbed the strap, preventing potential damage, "But they said the original plan took two months to complete."

"Their basic development is actually quite good.

I just need to use NURBS technology to make some adjustments to the shape and arrangement of the fan blades."

"What is NURBS?" Zhao Zhide felt as if he hadn't learned math or Chinese well.

"It seems you didn't listen very carefully," Xu Ning said, "This was mentioned in computer-aided geometric design research."

To adapt to his new role, Xu Ning had specifically reviewed relevant research to ensure he wouldn't make mistakes.

"Ah!

I really regret it," Zhao Zhide suddenly realized that if he had studied hard back then, perhaps he could be earning five thousand yuan now instead of just one thousand.

Soon, Zhao Zhide's beautiful fantasy was doused with a bucket of cold water by reality.

"Don't have too high expectations.

Advisor Shi's class only covered the theoretical basis; the real challenge lies in practical application," Xu Ning patted Zhao Zhide's shoulder and gently comforted him.

For Xu Ning, this task was not unfamiliar.

A long time ago, he had developed axial flow fans of almost the same specifications for an enterprise called Changhong Group.

This group originally specialized in producing military fire control radar, and even after transitioning to a manufacturer of civilian products, it still maintained close ties with the aviation industry.

Therefore, requesting external technical support was a common occurrence.

"Alright, it seems I won't be earning this money," Zhao Zhide shook his head, accepting the fact.

Then, he took out a small notepad from his pocket, quickly wrote down a string of numbers on it, tore off the page, and handed it to Xu Ning, "This is my pager number.

Just have the paging center notify me when you're done."

In 1996, Chinese character display pagers were very popular; they could not only receive digital information but also display short text messages, like a simplified version of modern text messaging services.

Xu Ning walked towards the library with his backpack, just turning back to wave at Zhao Zhide to indicate that he understood.

Although the third-year members of the Aerospace Engineering major were relatively relaxed during this exam week, members from other years and other majors were not.
