Chapter 901: Grumman's problem

"President Qin?"
Next to Qin Guan, Xiang Jing pushed him, he was distracted. Is this sweet and sour pork ribs so delicious?
Xiang Jing was very strange. Qin Guan hurriedly swallowed the ribs into his mouth, and then said: "We do business with sincerity. Since we have decided to buy with gold, we have made up our minds, but if the price is too expensive , Beyond the limit we can bear, so what else shall we talk about?"
Qin Guan's meaning is clear, we still want to buy, but don't take us as a fool.
"Especially, our country is still very poor. If it weren't for fighting the bear country, we wouldn't buy weapons with precious gold. We should invest more money in economic construction. Consistent with the interests of the Eagle Nation, we do not want the Eagle Nation to give us military assistance. As long as they give us the normal price, we will be satisfied."
Qin Guan said two points. It is not easy for the country to come up with funds. Don't take us as a fool. The price is normal. If the deal is still to be negotiated, the price is normal.
"Then President Qin, what kind of price do you think is normal?" Pellehake asked.
Now, General Thomas can no longer come forward. After all, he and Han Guo have already talked about it. If he asks Han Guo to go over and make a low price, his old face cannot be pulled down. It is best to let Grumman mediate from it. .
"Each ship does not exceed 200 million eagle yuan, and four ships 800 million eagle yuan. At the same time, we also hope that our warships will not be castrated. We need anti-submarine ships and anti-aircraft ships. We hope to equip us with standard missiles. Done."
Their reserve price, traded in gold, is equivalent to 220 million eagle yuan. Now let Qin Guan say that, of course the price is lower. After all, the missiles and helicopters above will definitely be sold by the other party.
Pellehake frowned: "President Qin, at this price, the Navy probably uses its own equipment and will not sell it. It's too cheap."
"Yes, let's just talk about something else, Mr. President, the cooperation between us is going very smoothly. We are receiving your equipment. I hope you will do your best in debugging."
Grumman’s titanium alloy welding equipment has been exported to Han, and now it’s time for the final commissioning. In fact, Qin Guan doesn’t care anymore. This equipment is just an introduction. They have to play tricks, and they can use the machine at any time. Find new ones in the cemetery.
With the possession of this set of technology, one's most critical variable swept wing part, that is, the wing box, has been able to be created, imitating the Tomcat, there is nothing that can be rare for oneself.
Correspondingly, we also exported the stealth machine technology to Grumman.
Hearing Qin Guan's change of topic, Pellehake could only follow his words and say: "Of course not, after all, you only gave us half the formula."
If you want to design a stealth machine, one of the most important is the electromagnetic reflection model. In addition to the electromagnetic reflection experiment in the laboratory, it also needs to be calculated theoretically. Among them, there is a very important calculation. formula.
The exploration of these formulas is difficult. Qin Guan can use the weapon data cemetery to get it out at any time, but if he goes to explore it himself, it will take a lot of hard work.
In addition to giving them the model of the stealth machine, these materials were also given to the other party at hand. Anyway, if you don’t give it, the Yingguo people themselves will make it. If you say the stealth machine, the technology of the Yingguo people is definitely the first. of.
The important formula is given, but the constant parameters in the formula are not given to them, so it can only be regarded as a half formula. Han is very cautious.
"The rest, we are also studying it ourselves, and when it comes out, we will naturally share it with you the first time." Qin Guan said.
Pellehak nodded: "Yes, we look forward to the next part, but we still have a problem."
Hearing Pellehake's words, the expression on Qin Guan's face was also very solemn: "What problem? Let's overcome it together."
"Using this formula, we can only simplify calculations and turn our aircraft's exterior design into planes. This is not aerodynamic. If we want to calculate further, the amount of calculation required is quite huge."
What Pelehak said is to study a major problem of stealth machines, computing power.
The world's first stealth aircraft in service is the F-117. The appearance of this aircraft is a combination of various planes. Why does this happen?
Because of their insufficient computing power, they can only use one plane as the result of the calculation.
When it comes to the B-2 stealth bomber, the fuselage has become a smooth transition, because with the development of computer technology, their computing power is already powerful enough to accurately calculate and refine the surface of the aircraft. To the surface.
A curved surface is still made up of small planes, and the amount of calculation increases geometrically.
For attack aircraft, it doesn't matter if the body is a plane. Anyway, there is no need to do too many maneuvers, but fighter jets will not work.
In order to conduct research in theory, it is necessary to make the surface of the body smooth through precise calculations. In this case, it needs more computing power than any supercomputer in this era.
The most advanced supercomputer, launched by Cray, has a computing capacity of over 250 million times per second, which has advanced the world's advanced computing power to 100 million times.
However, if they use this computer to calculate, they will need hundreds of years!
This result makes them very emotional. Without a more advanced supercomputer, it is absolutely impossible for them to refine the shape of the model. If the aerodynamic shape is not good enough, then it will not be advanced. Close combat ability.
The three generations of Eagle Country's aircraft are most valued for close-range combat ability, and this indicator cannot be given up.
When Pellehake said so, 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 to lead the whole world. This is a fresh trick and eats all over the world. Now Han has its own advanced processor chips, and I am worried that there is no suitable super Computer? "We can help solve this problem." Qin Guan said: "We are currently developing a supercomputer with a computing capacity of one trillion times. After this computer is successfully developed, we can help you with data calculations."
This help, of course, will not be free. What should Grumman offer to express gratitude? We are not short of money, what we want is technology.
