Chapter 901

"President Qin?"

Around Qin Guan, Xiang Jing pushed him. He was distracted. Is this sweet and sour pork chop so delicious?

Xiang Jing was very strange. Qin Guan quickly swallowed the ribs into his mouth, and then said, "we pay attention to sincerity in doing business. Since we decided to buy with gold, we have made up our mind. However, if the asking price is too expensive and exceeds our limit, what else should we talk about?"

Qin Guan's meaning is very clear. We still want to buy it, but don't kill us as a big enemy.

"In particular, our country is still very poor. If it is not to fight against the bear country, we will not buy weapons with precious gold. We should invest more money in economic construction. Our fight against the bear country is also in line with the interests of the eagle country. We do not want the eagle country to give us military assistance. As long as we are given the normal price, we will be satisfied."

Qin Guan said two things. It's not easy for the state to come up with funds. Don't treat us as the wrong big head. The normal price. If the transaction still wants to be discussed, then the normal price.

"Mr. Qin, what kind of price do you think is normal?" pelehak asked.

Now, general Thomas is no longer able to come forward. After all, he has talked about the collapse of the Han Dynasty, and then called the Han kingdom in the past. At a low price, his old face could not pull down, or let Grumman come to conciliation the best.

"No more than 200 million yuan for each ship and 800 million yuan for four ships. At the same time, we also hope not to castrate our warships. We need anti submarine ships and anti-aircraft ships. We hope to equip us with standard missiles."

Their reserve price is traded in gold, equivalent to 220 million Eagle yuan. Now let Qin Guan say so, of course, the price should be lower. After all, the other party will certainly tear down the supporting missiles and helicopters.

Pelehak frowned: "President Qin, I'm afraid the Navy will not sell its own equipment at this price. It's too cheap."

"Yes, let's talk about something else. Mr. President, our cooperation is going well. We are receiving your equipment. I hope you will try your best in debugging."

The titanium alloy welding equipment of Grumman company has been exported to the Han country, and now it is almost ready for final debugging. In fact, Qin Guan doesn't care. This equipment is an introduction. If they want to play tricks, they can find new ones from the machine tool cemetery at any time.

With the possession of this set of technology, the most critical part of your variable swept wing, that is, the wing box, has been able to be built. Nothing can be difficult to live on your side by imitating the male cat.

Accordingly, our side also exported the stealth aircraft technology to Grumman company.

When Qin Guan changed the subject, pelehak could only follow the meaning of his words: "of course not. After all, you only give us half of the formula."

If you want to design the stealth machine, one of the most important is the electromagnetic reflection model. In addition to doing electromagnetic reflection experiments in the laboratory, you need to calculate theoretically. In the middle, there is a very important calculation formula.

The exploration of these formulas is difficult. Qin Guan can use the weapon data cemetery at any time, but it takes a lot of hard work to explore it himself.

In addition to giving them the model of the stealth aircraft, these materials were also readily given to each other. Anyway, if they don't give it, the eagle people will work out it themselves. To say the stealth aircraft, the eagle people's technology is absolutely the first.

Important formulas are given, but several constant parameters in the formula are not given to them. Therefore, it can only be regarded as half a formula. Han is very cautious.

"We are also studying the rest. When we study it, we will share it with you at the first time," Qin Guan said.

Pelehack nodded. "Yes, we look forward to the next part, but we have another problem."

Hearing pelehak's words, Qin Guan's face was also solemn: "what problem? Let's overcome it together."

"Using this formula, we can only simplify the calculation and turn our aircraft appearance design into planes one by one, which is not in line with aerodynamics. If we want to make further calculation, the amount of calculation is quite huge."

What pelehak said is a major problem in the study of stealth aircraft, computing power.

The first stealth aircraft in service in the world is the F-117. The appearance of this aircraft is the combination of various planes. Why is this happening?

Because of their insufficient computing power, they can only use one plane as the calculation result.

By the time of the B-2 stealth bomber, the fuselage has become a smooth transition, because with the development of computer technology, their computing power is strong enough to accurately calculate the aircraft surface and refine it to the surface.

A surface is still composed of small planes, and the amount of calculation increases exponentially.

For attack aircraft, it doesn't matter that the body is flat one by one. Anyway, it doesn't need to do too many maneuvers, but the fighter won't work.

To study theoretically, it is necessary to make the body surface smooth through accurate calculation. In this way, it needs more computing power than any supercomputer in this era.

The most advanced supercomputer, launched by clay company, has a computing power of more than 250 million times per second, pushing the world's advanced computing power to 100 million times.

However, if you use this computer to calculate, they need hundreds of years!

This result makes them feel incomparably that without more advanced supercomputers, it is absolutely impossible for them to refine the shape of the model. If the aerodynamic shape is not good enough, it will not have advanced close combat ability.

The most important thing of eagle's third-generation aircraft is the ability of close combat. We can't give up this index.

When pelehak said this, Qin Guan immediately knew what the other party was thinking.

Sure enough, it is of great use to take the microelectronics industry as a breakthrough and lead the whole world. This is called a fresh move and eat all over the sky. Now Han has advanced processor chips. Are you worried about not having a suitable supercomputer? "We can help solve this problem," Qin Guan said. "We are currently developing a supercomputer with a computing capacity of one trillion times. When this computer is successfully developed, it can help you with data calculation."

Of course, this help will not be free. What should Grumman take out to thank you? We don't need money. We want technology.
