Rebirth of the 1980s: The Military Industry Empire
#525 - Chapter 525 Solve a Calculus Equation
The Sheraton Hotel was very large and high-end, as these visitors from the East knew, but they still widened their eyes when they were invited to the rooftop.
The rooftop was surprisingly unique!
Overhead was a grid made of raw wood. Although it couldn't block the sunlight, the shadows of the grid strips filled the ground with an artistic atmosphere. Now it was night, and a full moon hung overhead, divided into strips by the grid, looking very unique.
Holding a banquet could actually be outdoors!
Beneath the grid were tables and chairs, and many people were already sitting there, engaged in conversation. The men were all in suits and leather shoes, and the women were all in evening gowns, noble and elegant.
Among these people, Natalie was particularly dazzling. She already had an outstanding figure, and now, wearing a goose-yellow evening gown, she was even more alluring, and the gemstone necklace was just right, swaying back and forth between her peaks.
When she saw the visitors from the East, she immediately placed her empty wine glass on a tray held by a waiter and walked over gracefully.
Nie Xiaoqian glanced at her own attire: an ordinary floral dress, without any jewelry, and with even more ordinary plastic sandals on her feet. She immediately felt like Cinderella.
Could she be embarrassing Brother Yang?
"General Qin, welcome everyone to the banquet," Natalie said with a radiant smile. "General Qin, today our negotiations have made a breakthrough. We should celebrate! Some personnel from other military industrial units in Tel Aviv have also come to join the banquet. I'll introduce you later. Waiter!"
A waiter walked over, carrying two glasses of wine on a tray.
Natalie's slender fingers picked up a glass of wine and handed it to Qin Yang, a delicate ring on her index finger, exquisite and elegant.
Nie Xiaoqian immediately became nervous. What was Brother Yang going to do? Was he flirting with this woman?
"Is that so? What about me interests you?" Natalie puffed out her chest.
"At Rafael, they introduced you as the Deputy Chief Engineer in charge of the Python-3 missile. You're a technical person, right?"
"That's right," Natalie nodded.
"But your outfit at the company today made you look like you were in sales, and as for now, dressed so sexily, you look more like someone from the nightlife street below the bar. I'm very curious, are you really in technology?"
Hearing Qin Yang ask this, Nie Xiaoqian immediately smiled radiantly. Brother Yang was too awesome! He said that so well!
But, would Brother Yang's question make her angry and ruin this cooperation?
"Today's outfit at the company was because I was receiving you. Tonight's outfit is because this is a banquet. If it were a normal day in the research lab, I would also be in work clothes," Natalie said. "General Qin, different jobs and the attire between work and life are naturally different. These are very important, otherwise it would be considered impolite. What, do you doubt my identity?"
"Yes," Qin Yang nodded. "You'd better prove it."
"How do you want me to prove it?"
"Solve a calculus equation," Qin Yang said, then looked at Nie Xiaoqian beside him. "Did you bring paper?"
Nie Xiaoqian quickly took out her notebook. Qin Yang put the wine aside, took out the Hero brand fountain pen from his pocket, took the notebook, and scribbled on it.
Soon, he filled a page.
Natalie's expression was a little awkward. She didn't expect Qin Yang to actually be serious. What was wrong with this person? He wasn't moved by her beauty and even wanted to test her knowledge on the spot?
She got all A's in college, so why would she care about solving a calculus equation?
"Okay," Qin Yang tore off the page he had written on and handed it to Natalie.
"Okay, give me the pen too," Natalie took the paper and pen, and then immediately scribbled on the table next to her. Her handwriting was beautiful and fluent, and soon, she filled the entire table.
This matter aroused the interest of many people, and soon, a large group of people gathered around.
They held their wine glasses, watched the problem-solving process, and commented from time to time.
"Adaptive Simpson's method is more suitable for solving this equation."
"Actually, it's more convenient to write a program using a computer and call the quad function and quadl function to find approximate solutions."
Amid the discussion, a short man approached. Among the tall Westerners, he was very special: black skin, short hair.
He was just looking casually, but when he saw this equation, he suddenly widened his eyes, looked carefully for a few minutes, and then became excited.
"This, this equation is the simplified function of the canard layout flight control law! This function is used to solve the canard layout flight control program! Who wrote this equation?"
Canard layout, flight control program? Natalie, who was doing the final steps of the calculation, looked up in surprise. "Are you Easterners researching canard layouts?"
"Yes, we've been researching it for decades. We've accumulated a lot of experience in this area and summarized many equations," Qin Yang said. "After all, everyone knows that our Eastern engines are not good. If we want to develop advanced fighter jets on the existing industrial base, we have to find a way in aerodynamic layout."
As long as the engine is powerful, even a brick can fly into the sky, but what if the engine is not powerful? Then rely on aerodynamics!
The conventional fighter layout has the wings in front and the tail in the rear. Pitch operations rely on the horizontal tail. For example, if you want to climb, the horizontal tail turns downward, blowing air onto the top, so the tail has to go down and the nose is pried up.
The canard layout is the opposite, equivalent to placing the horizontal tail in front of the wings. If you want to lift your head, turn the wing surface upward, blowing air to the bottom, so the nose immediately lifts up. This layout of the aircraft is like a duck spreading its wings.
In professional terms, the canard layout provides positive lift, which is quick to operate, and the maneuverability of the aircraft can also be improved, so it is favored by aircraft designers in countries where engines are not powerful.
However, there are very few finished canard fighters. The biggest problem is that the wing surface operation of the canard layout is not linear. It has complex functional laws, and countless aircraft designers are tirelessly trying to understand this canard layout.
Now, the East was actually researching this technology, which made them very excited.
"How far have you researched?" the short man asked.
"Well, that's a secret."
The short man didn't know what to say for a moment and looked at the tall man beside him. This man was dressed in a suit and leather shoes, with black eyes, black hair, and yellow skin, but he had a hooked nose.
"I am Horev, an engineer from IAI. If you have time, you are welcome to visit our IAI company tomorrow," the man took out his business card.
"That's right, welcome to visit our company!" the short man also quickly invited.
Among the crowd, Old Song became excited.
