After landing the two drones, the next two drones were followed. After the launch, the test found that, except for the basic data slightly better than the previous coating, other aspects were not worse than it, which made it difficult to choose Up.

Lei Tiantang has also been with them to test until now. It is past 7 o’clock. Seeing that everyone has sorted out the data, Lei Tiantang clapped his hands and said: “Okay! First put these equipment and drones together. Take it back to the warehouse! Then wash your hands and eat! Test it again at noon tomorrow!"

Everyone also agreed that it is not too early now, and the test data needs to be tested several times before being compared. I only tested it once today. Now I want to make sure which one is impossible to choose, so I should eat quickly. !

At noon the next day, everyone had lunch early, and then dragged out various equipment and drones. Lei Tiantang also accompanied everyone to continue the test work under the high temperature of 40 degrees. Since it was lunch time, the company Many employees have also paid attention to this test, but like last night, Zhu Chenjie personally led the security team to pull the isolation belt here.

The stealth coating project is a highly confidential experiment. It has not been leaked apart from the company’s senior management and laboratory personnel. Of course, the current test is still confidential. The employees are just watching curiously, only knowing these few. The drone is a model of f22. I don’t know what it is testing. Although they have not been driven away, the security personnel still have to be on duty around to keep it secret.

Today's test will be the same as last night, but also test the durability of the stealth coating at high temperature and high speed, so today's test time will be longer than last night.

Time slowly passed. The first batch of stealth tests have been completed. Now they are conducting high-temperature and high-speed tests. Because the engine used by Lei Tiantang is a high-performance drone engine, it has also passed the Universe Technology Experts have magically changed, so the maximum speed of the drone can reach Mach 1.8, which is a veritable supersonic drone!

The reason why the drone can fly so fast is mainly because the interior design of the drone has been simplified as much as possible, and the high-strength graphene material provided by some material company laboratories is used, which reduces a lot of weight. There is nothing other than the instruments used for testing, so the quality of the drone is much lighter than that of the real drone. The speed that can be reached is also the result of several adjustments made by Lei Tiantang and experts. The reason is to test the performance of the stealth coating in a high-speed environment!

After half an hour of intermittent supersonic flight, the drone finally landed when the fuel was about to run out. As soon as it landed, everyone surrounded them. Lei Tiantang directly took a drone. On a table, it is more convenient to observe.

Experts in the laboratory applauded excitedly after using instruments to probe the surface coatings of the two drones! Because the result is so perfect! After such a long time of supersonic flight, today's outdoor temperature is so high, the combination of the stealth coating and the drone's fuselage is still unchanged as it was just painted!

After the results were announced, enthusiastic applause rang out. Although everyone has done a lot of experiments in the laboratory and confirmed the excellent stealth coating, everyone is still a little worried without the flight test. Now they can finally relax!

Through such a test, the stealth coating is basically a successful research! Now the results can be contacted by the military, let them use a professional radar to test again, fly a few times at supersonic speed there, and then they should be able to report for the real painting on the fighter for the final test!

Everyone was excited for a while and continued to work, because this is the first stealth coating, and there is one that has not been tested!

In another two hours, the two drones painted with the second stealth coating have also been tested, and their performance is also very good!

This is really a trouble of happiness! Suddenly, two stealth coatings passed the test, and the difference in performance was very small. Zhao Junxian wiped his sweat and asked Lei Tiantang, "Boss, what do you think of this situation? These two stealth coatings let me It hurts to give up that one. Wouldn't the military purchase two stealth coatings at the same time?"

"What are you thinking about! The military hasn’t tested it yet! It’s too early to think about purchasing! Since the performance of these two coatings are similar, then you can sort out their data and we will put them together They will be handed over to the military for testing, and then watch their test results and see how they choose!" Lei Tiantang said with a smile.

"Good boss! It's okay to send them all for testing! We also know what is wrong with the one who returned, and we can correct it when we study later!" Zhao Junxian smiled after thinking about it, indeed, thinking about it now It is too early for the military to purchase the stealth coating of its own home, and the time required for the military's test will certainly not be short.

Through the high-level police, Lei Tiantang contacted the high-level leaders of the Air Force. The leaders also heard about his company. Even the turbulent spy incident a while ago made Hongyuan New Materials dominate for several days. News headlines, so after learning about Lei Tiantang and they actually developed a stealth coating, he also attached great importance to it~lightnovelpub.net~ Mainly Lei Tiantang guaranteed that the stealth coating has passed various tests, and the performance is also very good. The high level of the military is still willing to believe in the guarantee of big entrepreneurs like Lei Tiantang. There is no good fruit to cheat the military!

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

Lei Tiantang personally received a group of military personnel, and when he met the leading military expert, he introduced himself: "Hello President Lei! I really admire a big name! I am the person in charge of this military operation. My name is Liu Leshan. A professor kept secret by the military!"

Lei Tiantang stepped forward and shook hands with this silver-haired but energetic expert, and smiled happily, "Welcome everyone to come! Professor Liu, thank you for your hard work! I believe this trip will not disappoint you!"

Then they shook hands with the others separately. Everyone was polite and visited their laboratory under the leadership of Lei Tiantang and Zhao Junxian. They were very satisfied with the new high-end equipment Liu Leshan in the laboratory, because they only have Only with such equipment conditions can a breakthrough in material development be achieved!
