Seeing such a big reaction from everyone, they all walked quickly towards the two engines, and seeing this, Li Tianfeng smiled happily.

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

Li Tianfeng said: "This is our two verification machines for the turboshaft D engine, these two engines have undergone a series of verification tests, and at present, they are temporarily placed here. ”

Everyone walked to the two engines, almost surrounded the two engines, these experts of the review panel, are the first time to see the real turboshaft D engine, see these two engines in front of their own, everyone's eyes are full of brilliance, and even someone stretched out their hands, gently stroking the engine.

"Mr. Li, you can see that the quality of these two engines is good at a glance."

"yes, it's not like an engine that's been tested for validation at all, it's a bit like a brand new engine that has just been assembled."

"Mr. Li, seeing such an engine, my heart is inexplicably happy."

"Yes, I didn't expect that we also have such an advanced turboshaft engine, which can be compared with developed countries in Europe and the United States, and I am very proud in my heart."

"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 narrowed a lot at once.

“……”

Experts, looking at these two engines, you say, I say, everyone's faces are full of joy and pride, Tianfeng Technology's entourage, seeing this, can't help but quietly look at each other, exchange eyes, everyone's eyes are full of joy.

Li Tianfeng's mood at the moment is also very happy. The experts have such a high evaluation of this engine, Li Tianfeng estimates in his heart that the type certificate of his turboshaft D engine should be a sure thing.

As the leader of the evaluation expert group, Zhang Hongzu also nodded again and again after taking a look at these two engines. According to Zhang Hongzu's professional vision, these two engines look very good in terms of design and appearance quality, as for the overall performance, Zhang Hongzu has long known from the relevant information.

Zhang Hongzu said: "Mr. Li, your two engines are really very good, I have seen many engines in China that have completed a series of verification tests. None of those engines can do this, and those engines can be used for a long time at a glance, and where can they give people the feeling of a new engine. ”

Li Tianfeng said: "Expert Zhang, our two engines, in a series of test runs, there is almost no oil leakage, after a long time of testing, the surface of the engine is still clean. ”

Zhang Hongzu said: "Not bad. Terrific. ”

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

Li Tianfeng nodded confidently, and thought in his heart, that is true, in these management. Especially in quality management and technical management, Tianfeng Technology must be first-class in China.

After looking at the assembly workshop for a long time, everyone was full of interest, and there was still a little time to take a look, Li Tianfeng said: "Comrades experts. Let's take a look at the test shop. ”

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

One of the experts said suspiciously: "Mr. Li, don't you have a test mission today?" Why didn't I hear a little test run. ”

Li Tianfeng smiled: "Our test workshop is in another place, and it is still several kilometers away from here. ”

"Oh, so it's not here." Everyone suddenly realized.

Zhang Hongzu said: "Mr. Li, after we looked at these two engines, we really want to go to the test workshop to have a look." ”

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

A few cars, in turn, went on Songzhou Avenue, and then went to the test workshop a few kilometers away, arrived at the gate of the test workshop, everyone got off the car, saw the environment here, and everyone was praised.

Here, the environment is first-class, spacious and elegant factory gate, outside the gate is an asphalt road, has been connected to Songzhou Avenue, the traffic is very convenient.

In addition, the environment is elegant, there are few people around the test workshop factory area for three or five hundred meters, a farmland and vegetable field, around the high wall of the factory, there are rows of tall poplar trees, at this time, the trees are luxuriant, which plays 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 testing!" ”

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

The sound of the engine test is coming from the factory, hearing the sound of the engine test, everyone has a burst of energy, the sound of the engine test, in everyone's ears, is not different from the most beautiful sound.

Zhang Haiping has a good understanding of Tianfeng Technology, and when he heard the sound of the test, he couldn't help but say: "Mr. Li, you are testing again, this is the engine life verification test?" ”

Li Tianfeng said: "Yes, it is the engine life test. ”

Zhang Hongzu said: "Mr. Li, you have started the life test, and the progress is so fast. ”

Li Tianfeng said: "The life test has been carried out for several days, but it will take a long time to get the final test results. ”

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

Li Tianfeng stretched out two fingers and was about to speak, when an expert next to him obviously saw the two fingers stretched out by Li Tianfeng, and couldn't help but be slightly disappointed, the expert said: "Mr. Li, such an excellent engine only has a 200-hour life test, which is too conservative." ”

Immediately, another expert agreed: "Yes, such an excellent engine, I think it will be at least 500 hours of life test." ”

"Yes, at least 500 hours, or even 800 hours of life testing."

Zhang Hongzu also shook his head lightly and said: "Mr. Li, 200 hours of life test, it is really a little conservative, I recommend that you carry out at least 500 hours of life test, or 800 hours of life test." ”

Li Tianfeng smiled happily.

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

Zhang Hongzu didn't dare to continue, because Li Tianfeng stretched out two fingers, if it is not a 200-hour life test, it must be a 2000-hour life test, definitely not 20 hours.

Everyone looked at Li Tianfeng with a shocked face, originally everyone was chatting and walking towards the factory, at this time, everyone stopped one after another, looked at Li Tianfeng in shock, and waited for Li Tianfeng's answer.

Even, an expert exclaimed: "Mr. Li, you are not conducting a 2000-hour life test!" ”

Li Tianfeng met everyone's gaze and nodded very confidently: "Yes, what we are doing now is a 2000-hour life test!" ”

What a 2000 hour life test!

Suddenly, several experts gasped and looked at Li Tianfeng in extreme shock, it was actually a 2000-hour life test, which completely subverted the record of the first life test of a new aero engine.

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

Li Tianfeng said: "We are carrying out a 2,000-hour life test, and after a 2,000-hour life test, if the engine is in good condition, we will add 1,000 hours to reach a 3,000-hour life test." ”

What the! 3000 hours !!

Everyone looked at Li Tianfeng in extreme shock, as a relevant expert in this field, everyone knows the gold content of 3000 hours of life test, such a time, absolutely set a precedent in China, even if it is placed in the world, it is also a very proud achievement.

3,000 hours!

Many experts, in shock, immediately began to calculate the overall life of the turboshaft D engine, the first turn period of 3000 hours, after each overhaul can be used for another 3000 hours, an engine can go through 3 overhauls, the overall service life of the engine will reach an astonishing 12000 hours.

Oh my God, 12000 hours!!

Thinking about the service life of the engine, an expert even opened his mouth in shock, obviously, it is the first time I heard that there is a newly developed engine in China, which can achieve such a lifespan, even if those aircraft engines that have been mass-produced for many years and have been very mature in technology, there are few service life that can reach 12,000 hours.

Amazing!

If you don't come to see it for yourself, who can imagine it, many experts thought so in their hearts, and the eyes of Li Tianfeng were obviously different.

Li Tianfeng was very happy to see everyone's reaction like this, and said with obvious joy: "Experts, our engine is being tested, let's go and take a good look." ”

"yes, go take a good look!"

At this time, everyone came back to their senses, and with Li Tianfeng entered the test workshop, they watched the test workshop for a long time, and also stayed in the test monitoring and control room for a long time.

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

The engine that was being tested seemed to be full of magic, firmly sucking everyone in, Li Tianfeng couldn't help but smile when he saw this, and looked at the time, it was already past the afternoon off-duty time.
