Chapter 152

After landing these two UAVs, they are followed by the next two. After taking off, the test found that except for the basic data slightly better than the previous coating, other aspects are not worse than it, which makes it difficult to choose.

Lei Tiantang also accompanied them to test until now, they didn't go to dinner. It was more than 7 o'clock. Seeing that everyone had sorted out the data, Lei Tiantang clapped his hands and said, "OK! Take these equipment and drones back to the warehouse first! Then wash your hands and eat! We'll have a test at noon tomorrow

People also agreed that it is not too early now, and the test data can only be compared after many tests. It is only tested once today. Now it is impossible to decide which one to choose. It's better to eat quickly!

At noon the next day, we had lunch early, and then dragged all kinds of equipment and UAVs out again. Lei Tiantang accompanied everyone to continue the test work under the high temperature of 40 degrees. Because it was lunch time, many employees of the company also paid attention to such tests. However, as last night, Zhu chenjie personally led the security team to open the isolation belt here 。

The stealth coating project is a highly confidential experiment, which has not been disclosed except for the company's senior management and laboratory personnel. Of course, the current test still needs to be kept confidential. The staff just looked around curiously and only knew that these UAVs were F22 models, and what they were testing did not know. Although they were not driven away, they were still kept secret The security personnel should be on duty around.

Today's test will not only be the same as last night, but also the durability of the stealth coating at high temperature and high speed, so the test time today will be longer than last night.

As time goes by, the first batch of stealth tests have been completed. Now the high-temperature and high-speed tests are being carried out. Because the engine used by Lei Tiantang is a high-performance UAV Engine and has been modified by experts from Cosmos technology company, the maximum speed of UAV can reach Mach 1.8, which is worthy of the name of supersonic UAV!

The main reason why the UAV can fly so fast is that the interior design of the UAV is simplified as much as possible, and some high-strength graphene materials provided by the laboratories of materials companies are used, which reduces a lot of weight. Besides, there are no other things on the UAV except for some testing instruments. Therefore, the weight of UAV is much lighter than that of a real UAV, This speed is also the result of several adjustments made by Lei Tiantang and experts. The main reason is to test the performance of stealth coating in high-speed environment!

After half an hour of intermittent supersonic flight, the UAV finally landed when the fuel was about to run out. As soon as it landed, everyone gathered around. Lei Tiantang directly and vigorously took a UAV to a table, which made it more convenient to observe.

Laboratory experts in the use of instruments on the surface of the two UAVs to carry out a variety of exploration, excited to clap! Because the result is so perfect! After such a long time of supersonic flight, and the outdoor temperature is so high today, the combination of stealth coating and UAV fuselage is still the same as the one just coated!

After the results were released, warm applause broke out. Although we have done a lot of experiments in the laboratory and confirmed the excellence of the stealth coating, we still have some worries in our hearts without flight test. Now they can finally relax!

Through such a test, the stealth coating is basically a success! Now the results can be contacted with the military, let them use professional radar to test again, fly supersonic there a few more times, and then should be able to report the real painting to the fighter for final test!

We are excited for a while and then continue to work, because this is the first stealth coating, there is a test of it!

It is nearly two hours time, coating the second stealth coating of two UAVs also completed the test, the performance is also very excellent!

This is really the trouble of happiness! All of a sudden, two kinds of stealth coatings passed the test, and the performance difference was very small. Zhao Junxian wiped his sweat and asked Lei Tiantang: "boss, what do you think of the situation now? These two stealth coatings make me give up which one is distressed. Won't the military purchase two stealth coatings at the same time? "

"What do you think! The military hasn't tested it yet! It's too early to think about purchasing now! Since the performance of these two coatings are similar, you can sort out their data, and we will send them to the military for testing. Then we will see their test results and see how they choose! " Lei Tian Tang said with a smile.

"Good boss! Send them to test! We also know what's wrong with the one who comes back. We can correct it when we study it later! " Zhao Junxian also laughed when he thought about it. Indeed, it is too early to think about the military purchasing the stealth coating of his own home. The time required for military testing is certainly not short.

Through the senior level of the police, Lei Tiantang contacted the senior leaders of the air force, and the leaders had heard of his company. Even though there was a heated spy incident some time ago, Hongyuan new materials company occupied the news headlines for several days. Therefore, he attached great importance to Lei Tiantang after he learned that they had actually developed an invisible coating.The main reason is that Lei Tiantang guarantees that the stealth coating has passed all kinds of tests, and its performance is also very excellent. For the guarantee of such big entrepreneurs as Lei Tiantang, the senior military officials are willing to believe it. There is nothing good to cheat the military!

So the military immediately arranged for experts to come to the material company to take samples and UAVs, to take these things back for detailed testing!

Lei Tiantang personally received a party from the military. As soon as he met the military leader's expert, he introduced himself: "Hello, Mr. Lei! I've heard a lot about you! I am the person in charge of this military operation. My name is Liu Leshan! A professor in the military's secrecy! "

Lei Tiantang shook hands with the silver haired but energetic expert and said with a happy smile, "welcome to your coming! Professor Liu, it's hard for you! I believe this trip will not let you down! "

Then they shook hands with other people, and they were polite. Then they visited their laboratory under the guidance of Lei Tiantang and Zhao Junxian. Liu Leshan was very satisfied with the new high-end equipment of the laboratory, because only with such equipment and conditions can we make a breakthrough in material development!
