Seeing everyone's reaction, they walked quickly towards the two engines. Seeing this, Li Tianfeng smiled happily.

Zhang Hongzu said: "Mr. Li, is this our turboshaft D engine?"

Li Tianfeng said: "These are two verification machines of our turboshaft D engine. These two engines have undergone a series of verification and test drives. At present, they are temporarily placed here."

Everyone walked to the two engines and almost surrounded the two engines. These experts from the review expert group saw the real turboshaft D engine for the first time. Seeing these two engines right in front of them, everyone's eyes were full of colors, and some people even reached out and gently stroked the engine.

"Mr. Li, you can tell at a glance that these two engines are of good quality."

"Yes, it doesn't look like an engine that has undergone a series of verified test drives at all, but it looks like a brand new engine that has just been assembled."

"Mr. Li, I was inexplicably happy to see such an engine."

"Yes, I didn't expect that we also have such an advanced turboshaft engine, which is completely comparable to developed countries in Europe and the United States. I feel very proud."

"Yes, with our turboshaft D engine, at least in the field of turboshaft engines, the gap between us and developed countries in Europe and the United States has suddenly narrowed a lot. Mr. Li, it is amazing to develop such an advanced turboshaft engine."

“…”

All the experts, looking at these two engines, you said and said, everyone's faces were filled with joy and pride. Seeing this, the accompanying staff of Tianfeng Technology couldn't help but look at each other quietly. After communicating their eyes, everyone's eyes were full of joy.

Li Tianfeng was also very happy at this moment. The experts have such high evaluations of this engine. Li Tianfeng estimated in his heart that the model certificate of his turboshaft D engine should be a foregone conclusion.

As the leader of the review expert group, Zhang Hongzu nodded repeatedly after looking at these two engines. According to Zhang Hongzu's professional perspective, both the design and appearance quality of these two engines look very good. As for the overall performance, Zhang Hongzu had known it from relevant information.

Zhang Hongzu said: "Mr. Li, your two engines are really good. I have seen many engines in China that have completed a series of verification and test drives. None of those engines can do this. You can tell at a glance that those engines have been used for a long time. How can they give people the feeling of a new engine?"

Li Tianfeng said: "Expert Zhang, there was almost no oil leakage in our two engines during a series of test drives. After a long period of test drives, the engine surface was still clean."

Zhang Hongzu said: "Not bad, amazing."

Another expert next to him also agreed: "Mr. Li, although we have not reviewed your quality management system, technical management system, etc., it can be seen from the excellent quality of these two engines that you must have done a very good job in those aspects."

Li Tianfeng nodded confidently and thought to himself, that is indeed, in these management aspects, especially quality management and technical management, Tianfeng Technology is definitely first-class in China.

I looked at the assembly workshop for a long time. Everyone was very excited and there was still some time to take a look. Li Tianfeng said: "My experts, let's go to the test workshop to take a look."

"Okay, I should go to the test workshop to take a look." Several experts immediately agreed.

One of the experts said in confusion: "Mr. Li, did you not have a test drive task today? Why didn't you hear any test drive?"

Li Tianfeng smiled: "Our test workshop factory area is in another place, and it is several kilometers away."

"Oh, it turns out that it's not here." Everyone suddenly realized.

Zhang Hongzu said: "Mr. Li, after we saw these two engines, we really want to go to the test workshop to take a look."

Li Tianfeng said: "Okay, then let's go to the test workshop."

Several cars went on Songzhou Avenue in turn, and then headed towards the test workshop several kilometers away, and arrived at the entrance of the factory area of ​​the test workshop. Everyone got off the car and saw the environment here, and everyone praised it again.

Here, the environment is first-class, spacious and grand factory gate, and there is an asphalt road outside the gate, which is connected to Songzhou Avenue, and the transportation is very convenient.

In addition, the environment is elegant, and there are few houses around the test workshop and factory area of ​​three or five hundred meters. There are farmland and vegetable fields. There are rows of tall poplar trees around the high walls of the factory area. At this time, the trees are lush, which has a good sound insulation effect.

One of the experts said: "Mr. Li, you really know how to choose a place. This is really a good place for engine test drives!"

Li Tianfeng said: "The place is good, and I am quite satisfied. Let's go into the factory and take a look at our test workshop, and also look at the engine we are conducting the test drive."

The sound of engine test drive was coming from the factory area. When everyone heard the sound of engine test drive, they were full of energy. The sound of engine test drive was no different from the most beautiful sound in everyone's ears.

Zhang Haiping knew Tianfeng Technology well. When he heard the sound of the test drive, he couldn't help but say: "Mr. Li, you are conducting the test drive again. Is this an engine life verification test drive?"

Li Tianfeng said: "Yes, it's the engine life test drive."

Zhang Hongzu said: "Mr. Li, you have already started the lifespan test drive, and the progress is so fast."

Li Tianfeng said: "The lifespan test drive has been going on for several days, but it will take a long time to get the final test drive result."

Zhang Hongzu said: "Life-life test drive is usually a long process. By the way, Mr. Li, are you doing a 300-hour life test drive or a 500-hour life test drive."

Li Tianfeng stretched out his two fingers and was about to speak. An expert next to him clearly saw the two fingers that Li Tianfeng stretched out and couldn't help but feel a little disappointed. The expert said: "Mr. Li, such an excellent engine only has a 200-hour life test drive, which is too conservative."

Another expert immediately agreed: "Yes, such an excellent engine, I think it will take at least 500-hour life test drive."

"Yes, it's OK to have at least 500 hours or even 800 hours of life."

Zhang Hongzu also shook his head gently and said, "Mr. Li, the 200-hour life test drive is really a bit conservative. I suggest that you perform a life test drive of at least 500 hours, or an 800-hour life test drive."

Li Tianfeng smiled happily.

Seeing this, Zhang Hongzu said in confusion: "Mr. Li, isn't it a 200-hour life test drive, but..."

Zhang Hongzu didn't dare to say it, because Li Tianfeng stretched out two fingers. If it wasn't a 200-hour life test drive, it would definitely be a 2,000-hour life test drive, definitely not 20 hours.

Everyone looked at Li Tianfeng with shock. Originally, everyone was walking towards the factory while chatting. At this time, everyone stopped and looked at Li Tianfeng in shock, waiting for Li Tianfeng's answer.

An expert even exclaimed: "Mr. Li, you are not doing a 2,000-hour lifespan test drive!"

Li Tianfeng faced everyone's eyes and nodded confidently and said, "Yes, what we are doing now is a 2,000-hour lifespan test drive!"

It's really a 2,000-hour life test drive!

Suddenly, several experts took a breath and looked at Li Tianfeng in extreme shock. It actually had a 2,000-hour life test drive, which completely overturned the record of the first life test drive of the new aircraft engine.

Zhang Hongzu also said excitedly: "Mr. Li, is it really a 2,000-hour life test drive?"

Li Tianfeng said: "We are conducting a 2000-hour life test drive and completing a 2000-hour life test drive. If the engine is in good condition, we will add 1000 hours to achieve a 3000-hour life test drive."

What! 3000 hours!!!

Everyone looked at Li Tianfeng in extreme shock. As an expert in this field, everyone knows the value of a 3,000-hour life test drive. Such time will definitely be a precedent in China. Even if it is placed internationally, it is a very proud achievement.

3000 hours!

Many experts, in addition to being shocked, immediately began to calculate the overall life of the turboshaft D engine. The first turnover period was 3,000 hours. After that, every overhaul can be used for another 3,000 hours. An engine can undergo 3 overhauls, and the overall service life of the engine will reach an astonishing 12,000 hours.

My God, 12,000 hours!!!

To understand the service life of the engine, an expert even opened his mouth in shock. Obviously, it was the first time he heard that there was a newly developed engine in China that could achieve such a lifespan. Even those aircraft engines that have been mass-produced for many years and are already very mature in technology have few service lifespans that can reach 12,000 hours.

Great!

Who would have imagined it if you didn’t come to take a look in person? Many experts thought in their hearts, and the look of their eyes at Li Tianfeng was obviously different.

Li Tianfeng was very happy to see everyone's reaction and said with obvious joy: "Dear experts, our engine is being tested. Let's go and have a good look."

"Yes, go and have a good look!"

At this time, everyone came to their senses. As Li Tianfeng entered the test workshop, he watched the test workshop for a long time, and stayed in the test control room for a long time.

Especially in the test drive monitoring room, through the huge thick soundproof glass, we saw the engine being tested on the test drive table, and everyone was reluctant to leave for a long time.

The engine that was being tested seemed to be full of magic, sucking everyone firmly. Seeing this, Li Tianfeng couldn't help but smile. After looking at the time, it was already past afternoon get off work time.
