After entering the control room, Wang Bin and the others found that there were quite a lot of people in the control room at this time. In addition to the necessary control personnel in the control room and Prof. Dai and Prof. Zhang, there were also many technicians in the control room. They all looked very excited, which made Wang Bin a little puzzled, but he immediately understood why.

Because among the ten engines, there are three engines that will complete 300 hours of verification test today.

After all, these three engines are different from the other seven, because these three engines have gone through 150 hours of non-stop testing before, plus this 150 hours of testing, so the completion time is naturally faster than the other seven half.

And now looking at the expressions of these technicians and Professor Poking and others, it is obvious that this verification test run is about to be completed, and it also marks that there were no accidents with these three engines during the test run, which also means It means that this engine already has the standard to be installed on drones.

At this moment, Professor Zha and the others finally found out that Wang Bin and others had arrived. Just as he was about to speak, Yang Lin who was beside Wang Bin spoke first, "Teacher, why are you here?"

Yang Lin was very shocked that Professor Zha appeared in Wang Bin's aerospace engine laboratory of Tiangong Science and Technology. You must know that Professor Zha was his mentor in college, and he was also the leader in the research and development of aviation development.

Moreover, Professor Zha also has a very high reputation in the domestic aviation development industry. According to the normal situation, even if Professor Zha retires, the unit will re-employ. The units are all the top talents.

In addition, even if Professor Po doesn't want to be in an official unit, he shouldn't appear in a small company like Tiangong Technology, but should stay in a company like Lanjian!

And when Professor Chi saw Yang Lin beside Wang Bin, he was also very surprised, so he said, "Hey! Xiao Yang, why are you here!"

At the same time, he looked at the people behind Yang Lin, and then said again: "Old Fang, Lao Yu...Why are you here, Lao Li?"

At this time, Professor Dai and Professor Zhang also looked towards this side, and were also very surprised, and then they greeted these experts.

Obviously, Professor Zha and Professor Zhang basically knew the experts who came to Wang Bin and Tiangong Technology for review, and they had a very good relationship.

"Poke Lao, I never thought that the engine developed by Mr. Zhang's Tiangong Technology was developed by you, teacher.

If we knew earlier that it was developed by you, we wouldn't have to come here for an audit. "Seeing his teacher here, Yang Lin was obviously very happy.

"Yeah! If we had known that you were here, we wouldn't have to come here..., we know your R\u0026D level,..." At this moment, other experts from the review team also joined in Open your mouth and say.

After hearing what the experts said, Professor Zha finally understood the purpose of these experts, and said to them with a smile: "Xiao Yang, and everyone, although this engine is developed by our Tiangong Technology, But the necessary procedures must be gone, I think, you also know my principles. As long as I open my mouth, this engine has already passed the inspection, otherwise, there is no need for you to come here. "

After listening to Professor Zha's words, Yang Lin and other experts nodded. They naturally agreed with what Professor Zha said.

As Professor Zha said, otherwise, with Professor Zha's energy, as long as he greeted them loudly, the project approval of this engine would not have to wait until now, it would have passed long ago.

Speaking of this, Professor Zha said again: "Xiao Yang and everyone, you are here at the right time today. We have a 300-hour verification test run for this engine of Tiangong Technology. Among the ten engines, three are about to be completed. Let's wait for the 300-hour verification test to be completed, and then go to my office to talk about the others!"

To exchange good books, pay attention to the vx public account. [Book Friends Base Camp]. Pay attention now, you can receive cash red envelopes!

"Good teacher, listen to you."

"It's just what we wish for! This also allows us to personally witness that your Tiangong Technology engine has successfully completed 300 hours of verification test......." Other experts also said.

After speaking, everyone turned their gazes to the screen in the control room.

However, when they saw the data on the screen, they were surprised, and Yang Lin couldn't help but said: "Teacher! The thrust of this engine has reached 15 tons?"

As this engine has been improving since the beginning of research and development, to the first and subsequent test runs, the maximum thrust without additional force has been greatly improved, and now the engine's The maximum thrust without afterburner has reached more than 15 tons.

This kind of thrust has already surpassed the thrust level of all engines currently in service in the country. Even compared with those advanced mid-thrust engines under development, this engine is not inferior in terms of thrust. It is no wonder that Yang Lin and the others are like this was shocked.

"What is this? This engine is still only a basic model. According to the calculations of me and Lao Dai, if nothing unexpected happens, we will carry out a series of upgrades on this engine. After it is fully formed, The thrust of this engine will reach at least 20 tons!" Professor Zha said excitedly.

At the same time, he still has something to say in his heart, that is, even if this engine is in its current state, it is actually only a first-generation machine. After it is improved to the second and third generations, the thrust of this engine can reach at least 22 tons. By the fourth generation, it can reach at least 25 tons. As long as the more advanced fifth-generation aircraft, until now, Professor Zha and the others have not calculated, but according to their estimates, the thrust will reach at least 30 tons by then.

Of course, Yang Lin and the others don't know about this. After all, they all think at this time that the engine developed by Prof. Jao and the others is already the third or even the fourth generation, because they have never seen such a large thrust. generation machine.

But even so, Yang Lin and the others' expressions suddenly became serious. After all, this is an engine with a maximum thrust of 15 tons without extra power! Such a high-thrust engine can definitely be used on many aircrafts. Even China's most advanced fighter jets, the thrust of this engine is definitely enough.

"Teacher, how long will it take for the 300-hour verification test run to end? I really want to see how this engine is after the 300-hour verification test run!" After watching for a while, Yang Lin asked Professor Po.

Professor Chi looked at the time, and found that there were less than ten minutes left before the end of the 300-hour verification test run, so he said, don't worry, there are still about ten minutes left.
