However, when Wang Bin and others were preparing to install the new engine on the test bench, most of the people in Tiangong Technology Company, which was a few kilometers away, were also paying attention to Wang Bin and his team. The situation, because of Wang Bin and his Tiangong Technology's research and development of aero-engines, is no secret to Tiangong Technology's employees at this time.

After all, the various parts of the engine are produced by Tiangong Technology, and the sound of the engine test is so loud, these employees naturally know that it is the sound of an aero engine.

Even people who don't know it will ask each other the moment the engine test sounds, and they will naturally know what it is.

Of course, when the sound of the engine test was just heard, all the employees of Tiangong Technology were very happy. You must know that this is an aero engine! This is real high technology! It is the crown of industry! And now they Tiangong Technology are actually developing aero engines.

And now it has been successfully developed and the test run has begun. This is definitely something to be proud of for all the employees of Tiangong Technology. After all, many of them have participated in the manufacturing of parts for this engine. No participation, this engine was also developed by their company.

So after the sound of the engine test run sounded, all the employees of Tiangong Technology also silently prayed in their hearts that the aero-engine developed by them could be successful this time.

But when everyone was listening to the screeching sound from the engine test in a happy mood, the sound of the engine suddenly disappeared, which made everyone in Tiangong Technology very puzzled. What happened? The experiment was successful or failed, so many people began to discuss it.

"Why did the sound of the engine disappear all of a sudden? What happened? Did the experiment fail?"

"Yes! But wasn't everything fine before? I don't think there should be any problems! I wonder if the experiment was successful?"

"I think it may be successful, especially when the engine sound was very sharp in the last few minutes just now. I think it should be an afterburner test. You must know that the afterburner of a general aero engine can last for tens of seconds. It is already very remarkable, and this aero engine of our Tiangong Technology has been working for a few minutes, I think it must be a success!"

 …

However, when the employees of Tiangong Technology were discussing, in the test workshop a few kilometers away, those young technicians finally installed the second engine on the test bench.

Although it is said that this is only the first test run, but Professor Chi and the others naturally prepared a spare engine just in case, and not only one spare engine, but as many as five were directly manufactured, that is to say, excluding the previous test run. That one, now in the workshop, there are four spare engines.

Soon, with the efforts of those young technicians, the engine was installed on the test bench, and then every component of the equipment was carefully inspected. After it was confirmed that everything was installed in place, everyone withdrew from the vicinity of the test bench again and re-installed the engine. Entered the control room and started a new test.

Although many items have been tested for the previous single engine, but because of the replacement of an engine, all test items must be overthrown and re-tested.

So not long after, in the test workshop, the screeching sound of the aeroengine sounded again, and the workers in the Tiangong Technology factory a few kilometers away,

The mood of mentioning it was finally put down, and I happily listened to the sound of the engine.

In the test workshop, Wang Bin and others looked at the engine that was being tested, but they were not as nervous as they were when the previous engine was tested. After all, the previous engine had already been tested for ordinary tests. It is impossible to think that there will be any problems.

"Old Dai! After the test run of the previous engine, let those young people disassemble it, take a good look at the damage of the engine, and record all the data at the same time. After all, even if it was the test run before, for It is also very important for this engine.

After all, this is the afterburner in the case of a cooling system failure, which allows us to better understand the operation of the engine, as well as the working condition and working time of the engine when the same type of failure occurs in the future. "As the test drive began, Professor Zha said to Dai Lao who was beside him.

Hearing Professor Zha's words, Mr. Dai also nodded, and replied: "Indeed, the data from the previous test run is indeed very important to us, and this truly simulates the state of the engine when the cooling system fails!

So wait a minute, I will personally take charge of this matter to check the internal situation of this engine and record the data! "

"That's good!" said Professor Pok!

After the new engine started to test run, the steps of the previous engine test were very normal, and no problems occurred. Of course, this was also expected by Wang Bin and others until the maximum thrust test was re-entered, that is, afterburner. During the combustion test, the faces of Professor Poo and others became serious again, and Wang Bin's mood also raised again.

It's just that Wang Bin's worries seemed a little unnecessary, and the condition of the engine far exceeded the expectations of Wang Bin and Professor Cuo and others. The engine continued for nearly an hour in the afterburning stage before slowly Start to slow down, of course, this is not because there is a problem with the engine, but because the fuel prepared by the professor and others is not enough for the test run to continue.

After all, although the aero engine has a strong working efficiency, the fuel consumption of the engine is also very amazing. In less than an hour, it has already burned dozens of tons of fuel. This is definitely a real money burn.

You know this is aviation kerosene! The price per ton is more than 3,000. Even in this year's special situation, the price is as high as 2,899. That is to say, Wang Bin and his team's test drive this time, in less than an hour Hundreds of thousands were burned, if you add the loss of the engine, the kerosene burned by the previous engine and the engine itself.

The money burned by their Tiangong Technology during this test drive is definitely more than tens of millions, which makes Wang Bin really feel a little bit, aero engines are really not something that ordinary companies can play.

If it is an ordinary company, not to mention developing the engine, even if it is burned during the test run, it is enough to make them bankrupt.

As the aviation kerosene they had prepared was exhausted, it also meant that the test run was a perfect success. The data far exceeded the expectations of Professor Zha and their staff, and exceeded the design data of the drawings. In the entire test run workshop, all The young people cheered all of a sudden, everyone jumped and shouted, hugged and hugged, and some people threw their hats high.

Even if they poked the professor's face, they finally showed a smile.
