As for how long it will be stable, everyone doesn’t know, but Lei Tiantang told Zhu Chenjie and others not to worry too much. On the one hand, he will arrange for Yumi Akiyama to come to the company after a while and upgrade the company’s security system again, and then the most important thing. The thing is that their stealth coating has to be tested! When the time comes, people in the military will definitely upgrade their company security again! This basically guarantees foolproof!

Now that these spies have been wiped out, Lei Tiantang completely put the matter down. Of course, he also knows that this time the matter is definitely not over, because even after the country has issued a warning, the dark web has about their company. The mission has not been cancelled! I just changed a website to avoid the blow!

Lei Tiantang doesn’t bother to care about them for the time being. If he dares to come again, he will spare the time to run a few more times. He won’t notify the police if he comes again, and the scum will not disappear. This kind of action will not stop. Those behind the scenes, if you encounter them when you go out in the future, you must teach them a lesson. It is not his style to be bullied and not fight back!

However, during this period of time, he was not busy with this matter. He even pushed back to teach the little dwarf in Baga, because the company's stealth coating research plan has been basically completed, and two materials have passed the experiment. All the experiments in the laboratory will now be tested through actual combat!

Of course, it is impossible to notify the military at this time. You need to make a few drones, and then fly a few times after applying the stealth coating, and finally determine which sample to choose as the final product to notify the military.

It is very easy to make a drone, because Lei Tian Tang took out the design drawing, which is actually a drawing based on the reduced scale of f22. Of course, Lei Tian Tang still made a little modification. After all, the drone is essentially Fighters are still different.

I took the design drawing and came to the old factory of the material company. The robot laboratory equipment of the Universe Technology Company has been basically installed. It is very easy to use the equipment there to make a few drones.

The most important thing is that many of the technicians there have played model airplanes, so Lei Tiantang gathered these people together to make drones.

The process was very joyful and everyone was full of enthusiasm for this matter, because since I started with the company, everyone is either studying or designing rockets on the computer. It’s a bit boring to do this for a long time. This matter is just for everyone. Taste.

Everyone is not surprised by the f22 design drawing that Lei Tiantang brought, because the whole drone has the same appearance as the f22, and the internal engine and the like are only high-end drone accessories, and the f22 design drawing It's already available online.

With the joint efforts of everyone, the 4 drones were quickly manufactured. They are all exactly the same, except that the final stealth coatings are different. There are 2 of each coating, so that the experimental data can also be compared. .

At exactly 5 o’clock in the afternoon that day, four drones painted with two stealth coatings stopped on the longest road in the company. The multi-frequency radar built by the company’s laboratory was also erected. Some other test equipment are also placed on the side of the road.

The reason why the experiment was delayed until the evening was that the autumn tiger was too powerful. The highest temperature during the day reached 40 degrees. The first experiment is better at room temperature. If the test passed this afternoon, it will be again at noon tomorrow. Perform tests at high temperatures.

Since they were already testing large drones, they still notified the police, and then the police and the military applied for airspace. They applied for mid-to-low altitude airspace, and the sky above the industrial park was not a place where civil aviation routes passed. , So the application was quickly approved.

The experiment was carried out in two batches. Each time they flew two planes with the same coating. After all the preparations were completed, Zhao Junxian said to Lei Tiantang standing next to him: "Boss, they are all ready and ready to fly. Up!"

"Let’s start! Let’s see how it turns out! It’s been so long, I hope there is a good answer!" Lei Tiantang smiled and waved his hand to indicate that he could start. As for the quality of the drone, he was not worried because he was manufacturing After completion, they have all gone through several low-altitude flight tests, and some minor problems have been solved, so now they can take off directly.

"Attention from all departments! The test has officially started! The plane takes off!" After receiving Lei Tiantang's consent, Zhao Junxian directly arranged the test to start!

I saw two gray drones ignite at the same time, and then the engines glide on the highway for a certain distance with a blue flame, and then gently jumped up. In less than a minute, the ground was invisible to the naked eye. When they arrived, the people who stared at them also withdrew their gazes, and everyone stood in front of each monitor screen to watch their real-time dynamics.

After the instrument showed that the drone has reached an altitude of 2,000 meters, various tests have been officially launched. The radar has been scanning the drone when it takes off. It can still be detected in the initial stage, but After the drone rose to an altitude of 2000 meters and the flying distance was 30 kilometers away from the industrial park, the two drones disappeared from the radar screen!

If it weren’t for the positioning device on the drone, you might think that they don’t exist anymore. Of course, the radar doesn’t use only one waveband to scan. Although the laboratory experts are not specialized in radar, The performance of the radar modified with high-performance civil radar is also good, especially the radar bought by the experts has added a variety of frequency bands, which is no problem for testing.

The drone pilot manipulated the drone to hover in the airspace between 2000 meters and 3000 meters, controlling their distance from the radar. After nearly an hour of testing, it was found that only when the drone is within 30 kilometers of the radar, The radar can detect them!

This data is already amazing! According to public information, the range of stealth fighters found by radar in various countries is basically between 100 kilometers and 200 kilometers. Now the stealth coating made by our company can actually reduce this range to 30 kilometers. This number is estimated to be Even the most advanced stealth fighters in various countries can't reach it!

Of course, the data they are testing now can only be a rough figure. One is because the radar they used for testing is after all a civil radar modification, and the performance is definitely not as good as the radar used by the military. Another drone for testing The size is also incomparable with real fighters, so the final data still needs to be coated on privacy fighters for testing!
