However, there is one thing he still agrees with Wang Bin's words, that is, if this engine can persist in such extreme weather conditions, then there is really no condition for this engine to persist in the future.

However, when Professor Zha was thinking about this, the verification of this project, after half an hour of test drive, finally came to an end.

Although during the process of verifying the test drive, Professor Poking was also very nervous. After all, there are ice cubes with a diameter of one centimeter or even larger in these ice chips! But now it's finally over.

With the end of the ice swallowing verification test run, this proven engine was disassembled again by the laboratory staff and a new engine was installed again to start the sand swallowing verification test run, although the sand swallowing verification test run process The diameter of the gravel used in the game is not like swallowing ice, there are sands with a diameter of one centimeter, but the sand with the largest diameter, it should not be said that small stones have reached 0.5 centimeters.

In addition, the hardness of the sand is worse than that of ice, so in fact, the sand swallowing test run is more stressful for the engine, but fortunately, in the end, the engine survived the same as the previous ice swallowing test drive. It took half an hour to verify the test run.

With the success of these several verification test runs by the followers, Professor Pok finally relaxed his gripping mood, and he is also very confident in the engine they developed. After all, this engine can operate in such a harsh environment. He really can't think of any engine in the world that can match this engine.

Of course, after the verification of so many subjects, the development of Professor Zha and others is not over yet, because there is still a verification test that has not been completed, and that is the verification of foreign object impact.

After all, when the aircraft is flying in the air, it is inevitable that it will be hit by birds, or even directly involved in the air intake of the engine, which will cause the engine to malfunction.

In fact, in all aircraft accidents, the probability of being struck by birds is very high, so as an aircraft engine, the ability to resist the impact of flying birds is also a very important performance.

The last verification is naturally the anti-collision performance of this engine, and the birds they developed and used this time are not ordinary bird strikes, but directly use a chicken as the protagonist of this collision, after all Now most of the birds are national protected animals, so they don't want to sit in the classroom because of imitating the bird strike this time.

Of course, the chickens they use are not live chickens, but chickens that have long since ended their lives.

However, compared to the previous verification test runs, this time imitating the impact of birds, Professor Po and others are not very nervous, because according to the design data, this engine can completely withstand the impact of any birds, even It is no problem for a bird as big as a chicken.

Sure enough, after changing the engine, these verification tests also passed the test easily.

"Okay, today's verification and test run project really wanted to go well, but the result was a little better than I expected, so that's all for today's test run, everyone, get ready, and disassemble these engines tomorrow to see what's going on inside. .” After Professor Chi relaxed, he said to everyone.

Similarly, as one of the persons in charge of the R\u0026D and verification test run of this engine, Professor Zhang felt relieved after seeing the successful verification test run.

However, when his mood relaxed, he felt that something was wrong with him, he felt that his eyes were a little dark, and at the same time he felt that his hands and feet were a little weak.

Just after Professor Zha finished speaking, Professor Zhang finally couldn't hold on anymore, felt his eyes darken, and finally lost consciousness.

And when Professor Poking next to him just finished speaking, he also felt that something was wrong with Professor Zhang's situation.

Before he could speak, he saw Professor Zhang fall to the side all of a sudden. Fortunately, he reacted quickly and hugged Professor Zhang in time.

"Old Zhang! Old Zhang! What's wrong with you, wake up."

"Old Zhang! Old Zhang!" Professor Dai at the side also noticed the situation here and hurried over.

"professor Zhang!......."

"...."

After Professor Zhang fell down, the whole laboratory suddenly became very chaotic. Some picked up the phone and called the ambulance, some dialed Wang Bin's number, and some were at a loss.

"What! Something happened in the laboratory. Professor Zhang fainted!" He was in the laboratory. When Wang Bin received the situation in the aerospace laboratory, he was very nervous. In the laboratory, the unfinished experiment didn't care about continuing, but immediately walked out of the laboratory in a hurry, heading towards the direction of the aerospace engine laboratory.

Soon, Wang Bin came to the laboratory and saw Professor Chi and others in the lounge of Professor Zhang in the laboratory. At this time, Professor Zhang was lying on the bed in the lounge.

"Professor Zha, how is Professor Zhang doing now?" Wang Bin hurriedly asked Professor Zha who was sitting by the bed after he came to Professor Zhang's lounge.

"I don't know what's going on, but I don't think the problem is too big. It's probably because I'm too tired. After all, the task of the laboratory has been too heavy during this period of time. Except that the laboratory is developing In addition to this engine, Professor Zhang and others also need to understand and upgrade the drawings of that large fighter, which is a lot of work.

So during this period of time, Lao Zhang and the others worked late every day, and came to the laboratory early in the morning. Not to mention Lao Zhang and his age, even young people might not be able to bear this kind of work intensity. "Professor Poke said.

"What? Working late at night and coming to the lab early in the morning?

Professor Pok, why don't you persuade Professor Zhang and the others! Even if you can't persuade me, you should tell me! "Wang Bin said with a frown.

"Hey! It's not that we haven't persuaded them, but they don't listen, so what can I do.

Originally, I wanted to tell you this matter a long time ago, but during this period, since it is the critical period of our engine test run, we did not tell you. We want to wait until the engine’s 150-hour durability test run and swallowing It was reported that the verification test run such as swallowing sand and ice was completed, but unexpectedly, this kind of thing happened just after the completion of the verification test run of swallowing ice and sand. "Professor poking at this time also had a look of remorse.

At this time, Wang Bin also had a look of remorse. After all, if he had noticed the situation here earlier, perhaps what happened today would not have happened.

However, when Wang Bin was thinking about this, the siren of an ambulance came from outside the laboratory. Hearing this sound, Wang Bin and the others hurriedly carried Lao Zhang out of the laboratory and came to the door of the laboratory. , and the ambulance just arrived at the door of the laboratory at this time.
