Chapter 481

Compatibility alone must be a headache.

Qin Guan also decided to come and have a look after hearing that there were many problems here.

The 6611 Research Institute finally grew up. They didn't have to worry about everything. They disassembled the J-7 2M and J-7 E. after seeing the avionics inside, they knew they had found it. Qin Guan was more relieved. However, Marconi Company is not a good bird. Let alone the price of the later introduction negotiations, let's talk about the current technology, They will certainly shout that their side is no problem, it's the plane and so on.

If it had been a few months ago, Qin Guan might have used all kinds of tricks to negotiate with Marconi Company and finally obtain benefits, but now it is no longer necessary.

At any time, you can find out the technical data of Marconi Company in the 1980s, and then hand it over to your own electronic technicians for production. If there are any chips you have not seen, you can also find the data of the chips and hand them over to the chip factory for imitation.

Now I still negotiate with Marconi Company, but I'm afraid to show my feet and let the world know that Han has suddenly become a scientific and technological power.

First introduce, and then self-produced. In this way, we can explain to the outside world that our Shanzhai ability is the first. As for the patent right, go to hell. Qin Guan won't care.

Bincheng is very close to the capital, so Qin Guan can drive there almost the same day.

Now, we have caught up with this specific problem.

Mr. Tu wanted to say that obviously both of our planes are OK, but this problem happened to the newly modified fighter here. It's very strange.

Our side suspected that the radar equipment produced by Marconi Company could not reach the performance data they said. They were making a fake, while the people of Marconi Company thought that our side was whimsical and could not have done it.

The two sides have different views, and there is no good coordination at all.

Qin Guan came to the nose.

These experts of Marconi Company just want to simplify the problem. I can't solve it. It's wrong to do so, so it's over.

However, on the Han side, we must turn the impossible into possible. This is the contradiction.

What's the problem?

Other fighters of later generations either air intake on both sides or air intake on the belly, in order to reserve the position of the nose to install radar, but the J-7 fighter is air intake on the nose. It can only find a way on the air intake cone. The caliber is very small, and it has to move back and forth continuously. There are indeed many technical problems.

However, when it comes to the serious decline of detection performance, Qin Guan remembered something and said to the people present: "is this material problem that blocks too many radar waves, resulting in too little radiated electromagnetic wave energy?"

The cover of the air inlet cone is still the same. It is equipped with a radar. Although this thing can also penetrate electromagnetic waves, its permeability will be greatly reduced.

There is no mature airborne radar in China. I don't know how serious the texture of the radome is. As for Marconi's experts, they don't want to work harder on it at all.

Qin Guan was very clear, because Xiong state in the north had suffered losses on the radome. At that time, their first interceptor loaded with large-diameter radar, su-15, used air intake on both sides to free up the nose to load radar.

As a result, Xiong Guoren was surprised to find that the radar could not achieve the performance in the laboratory. What's the matter? It took several months to find the problem. It turned out that the radome buckled outside failed!

And this is the first time that Han did it.

Yes! As soon as Qin Guan said, Tu laodun reacted. There may be a problem here!

"Take this cover apart and let's do an experiment on the ground," said old Tu.

Qin Guan turned to the experts of NiuGuo again and said, "please wait here for a while. Can we look for problems together?"

Jack knows that Qin Guan is terrible. At the beginning, Qin Guan was aggressive in Luoluo company. Now, Qin Guan may have this problem. Let's try.

"Anyway, our radar must be all right," Jack said. "Let's have a look here."

Soon, the radome was disassembled, and the fighter could not start the engine, otherwise the air inlet cone could not complete the air flow regulation without the cover. The tester looked at the radar screen in the cockpit, and after a few minutes of preheating, the clear image was displayed.

"Find the target, very clear!"

Facing the sea, there is no shelter. As long as the radar antenna on the nose is slightly upward, you can see the aircraft over the sea. At this time, two navy J-7 are conducting flight training on the sea. Looking at the radar screen from here, it is quite clear that the target is definitely 20 kilometers away!

"Look, I said our radar is OK?" Jack said. "There is a problem with the radome you made yourself. You must replace it. If you don't have it, you can order it from us, but the price..."

No company is interested in this kind of small radar. After all, the nose space is so large. Who will engage in this kind of chicken rib? This is unique to Marconi Company. Of course, the price can't be low.

The other party can't even get a radome. It's just time to blackmail them again!

Before Jack finished, Qin Guan saw Xiang Jing coming in a hurry.

"Lieutenant General Jamal, the first deputy chief of staff of the air force of the holy Kingdom, has seen the J-8 and is flying to our 30lipu airport to see our new J-7." Xiang Jing said to Qin Guan.

This is the news I just received. I didn't expect that it's a good time for my side to come here today. It's another big customer!

Holy country? Qin Guan was also very happy to hear that. Yes, he had been only concerned with the negotiation of the date country and had forgotten the great customer of the holy country.

The holy state and the white elephant state are old enemies in history, and the enemy of the enemy is a friend. Therefore, the relationship between the holy state and the Han state is very good. In every war, the Han state fully supports the holy state, and the Han state also accounts for more than half of the weapons and equipment of the holy state, including the jian-6 fighters.

After more than ten years of wind and rain, these J-6 fighters have been in an aging state and their performance has fallen behind. Therefore, the holy state needs new fighters to replace them.

F-16？ The price is too high, and it is certainly impossible to equip a large number of equipment. Then, the new J-7 is definitely the best scheme for the holy country.

Jack was also very happy when he heard this. Marconi Company valued this project. Although they were high on the ground, he also hoped to sell more.

"Come on, buckle up the radome!" Jack shouted. At this time, for the first time, he stood in the same camp with the Han people.
