This delicate and beautiful engine is lying quietly on the test bench, and several workers are doing the final inspection, and all the wiring and pipes of the engine have been connected.

After about a few minutes, the workers exited the test bench, the doors of the test bench began to close, and the huge air inlet fence began to slowly open.

A technician in charge walked over quickly and reported loudly: "Mr. Yu, Chief Engineer Yi, everything is ready to enter the test procedure." ”

Yi Chunhua looked at Yu Shaoguang.

Yu Shaoguang nodded lightly. The test is about to start, some people are inevitably happy and slightly nervous, the whole test control center is gradually quiet, and the test drivers and technicians are in place. Tang Fei and Zhang Ping also sat down in their chairs, waiting for the test run to begin.

At 10:20 a.m., the first test alarm bell rang throughout the entire test center factory, and everyone knew that the test run of the drone engine was about to begin.

At 10:25, the alarm bell rang for the second test drive!

At 10:30, the third test alarm bell!

Yi Chunhua said loudly: "According to the test outline and test procedure, start the official test run!"

As soon as his words fell, a technician in charge personally pressed the green start button, and the engine on the test bench began to start at low speed.

The whole set of test technology outline comes from the system, which is provided by Jiuzhou Industrial Group at the beginning, which is very scientific and detailed, what to do in the first step, what to do in the second step, clearly.

Test runs!

The test takers and technicians operate in an orderly manner and in strict accordance with the test technical outline. Tang Fei looked at it seriously, and from time to time looked at the engine on the test bench through the glass, and from time to time looked at the instruments and meters in the test control center, as well as the data on the display screen, and so on.

Time passes by minute, minute by minute.

A satisfied smile appeared on Tang Fei's face. At this time, whether it is the technicians, or Yi Chunhua are happy, the test run is here, everyone knows that the data is very good, fully in line with the data requirements on the test technical outline.

Zhang Ping also seemed to see something, but he was not sure, he cast an inquiring glance at Tang Fei. Tang Fei nodded lightly.

The test took about an hour or so.

When the engine stopped on the test bench, the entire test control room erupted in earth-shattering cheers, and then everyone applauded violently.

Yi Chunhua said loudly: "This is the smoothest and most perfect time for our test run, and the data fully meet the requirements of the test technical outline, which is really unbelievable!"

The test was a great success!

Tang Fei was completely relieved, and Zhang Ping was a little excited: "Mr. Yu, Chief Engineer Yi, that is to say, the performance and quality of this engine are very good!"

Yi Chunhua said in a very affirmative tone: "Yes, whether it is performance or quality, it has exceeded our expectations, it is very good." ”

The system is produced and must be a high-quality product!

This is the system design of the engine, the comprehensive performance is very good, even the engine manufacturing technical data is also from the system, 336 factory in strict accordance with these technical data production, the quality of the engine is also very good, just when the test is both comprehensive performance and engine quality are reflected.

Seeing Yi Chunhua say this, Zhang Ping was completely relieved and happy, "Mr. Yu, Chief Engineer Yi, you have made great contributions, and our first engine is truly manufactured." ”

Successfully passing the first test run means that the engine has been successfully built.

Yu Shaoguang said modestly: "It is mainly the credit of Jiuzhou Industrial Group, if there is no detailed technical information, if there are no metal materials provided, if there is no them to help us process those high-precision parts, our engine cannot be manufactured so smoothly." ”

Tang Fei smiled and said, "Mr. Yu, you are too modest. ”

After everyone gave in, Yu Shaoguang said: "It's now twelve o'clock at noon, let's go to dinner first, and in the afternoon, we just go to the aircraft assembly workshop to see the decomposition of this engine." ”

According to the requirements of the technical outline of the test run, the engine will be returned to the aircraft assembly workshop for disassembly, disassembly into parts and components after the completion of the first test run, and then carefully inspected.

The main thing is to see if there is any impact on the engine parts after a test run, if it has an impact, it is more troublesome, and it is necessary to carefully analyze the reasons and take measures.

Tang Fei and Zhang Ping readily agreed, and everyone went to eat first.

The group got out of the test plant, got in the car and left, and went to a nearby farm with a good environment. Yu Shaoguang had already prepared and had already prepared a sumptuous lunch there.

Everyone didn't drink alcohol, only some drinks, because there was still very important work in the afternoon, and we needed to see how the engine parts were disassembled.

After dinner, at about 2 p.m., everyone walked into the aircraft assembly center, and by this time, the engine had already begun to be disassembled and disassembled.

Several key technicians are already there, and several workers are already skillfully and quickly disassembling the engine.

Disassembling is much faster than assembling, assembling an engine, if it is the first assembly, it often takes several days, and it only takes less than an hour to disassemble the engine into several major parts.

These major components are further disassembled, and finally disassembled one by one parts, these parts are neatly placed on the inspection platform, several experienced quality inspectors wear white gloves, holding flashlights, carefully checked, and even those few technical backbones are also checking the situation of some key parts.

Everyone walked over.

Yi Chunhua came over with a few pairs of white gloves and gave Tang Fei and Zhang Ping a brand new pair of white gloves. Tang Fei put on his brand-new white gloves and walked to the neatly arranged parts with great interest, and first picked up a turbine blade and looked at it.

Seeing this, Yi Chunhua was secretly stunned, and thought in his heart, it seems that Tang is always an expert, and he knows that the first thing to look at is the turbine blade.

Generally speaking, the engine has the greatest impact on the turbine blades after the test run, and the service life of the turbine blades is also the shortest in the whole engine.

Tang Fei picked up one of the turbine blades and looked at it, then nodded slightly, in his professional eyes, this turbine blade basically had no impact.

I looked at several other turbine blades in a row, and the situation was similar. Then, Tang Fei looked at some other parts, and after seeing a few key and important parts, Tang Fei gradually felt relieved.

This test run basically did not have much impact on the parts of the engine.

The quality inspectors and key technicians are working hard, meticulously checking the appearance of each part, or carefully re-measuring the dimensions of the parts and recording them.

Seeing that Tang Fei didn't continue to hold the parts and look at them, but took off the white gloves he was wearing, Yu Shaoguang invited: "Mr. Tang, Director Zhang, let's go take a rest, and leave the matter here to Chief Engineer Yi and them." ”

Yi Chunhua also said: "Mr. Tang, Director Zhang, don't worry, there will be results tomorrow morning, and I will report the situation to the two of you in detail tomorrow morning." ”

Tang Fei also felt that there was no need to inspect these parts in person, because he was already more relieved in his heart, and readily agreed: "Okay, then let's go and rest for a while." ”

Yu Shaoguang took Tang Fei and Zhang Ping to his office building and entered a reception room, where everyone sat and drank tea while chatting about the day relaxedly.

The first test run of the engine performed well, and the pressure on Yu Shaoguang's heart was greatly reduced, and his heart was relaxed.

The next day.

Tang Fei and Zhang Ping went to the aircraft assembly center of Factory 336, where Yi Chunhua gave a detailed introduction to the inspection of various parts and components after the engine test.

After a thorough inspection, it was concluded that the engine parts had fully withstood the first test test and that nothing had changed.

After Yi Chunhua reported the situation, he said confidently: "We are full of confidence in this engine, no, it should be said that we are full of confidence in this engine, we will reassemble this engine, and then conduct a second test run, and then it will be 100 hours, or even 300 hours of long test." ”

"Many parts of the second and third engines have been manufactured, and we will hurry up the manufacturing of the parts that have not yet been completed, and it is estimated that the final assembly of the second engine will start around New Year's Day......"

The excellent performance of this engine gave him full confidence, and he was obviously ready to make a big move, ready to speed up the production of the second and third engines.

According to the plan, the first engine will be used mainly for test validation and not for delivery. The second and third engines were delivered to Jiuzhou UAV and will be installed on the first UAV in the future.

Tang Fei said: "Chief Engineer Yi, I am waiting for your news, and I also eagerly hope that you will manufacture the second and third engines as soon as possible and deliver them to Jiuzhou UAV Company." ”

"Definitely, definitely. Yi Chunhua promised: "We will manufacture the two engines as soon as possible and deliver them to Jiuzhou UAV Company as soon as possible." ”

Hearing the conversation between the two, Zhang Ping became happy, relieved, and laughed.

After lunch, Tang Fei and Zhang Ping happily left Factory 336. Zhang Ping returned to the capital, and Tang Fei returned to Shenhai City and his Jiuzhou Industrial Group.

A few days after returning to Shenhai City, Tang Fei received a fax from Europe, inviting Tang Fei to go to Europe, because the first metro locomotive of the London Underground project had been successfully dropped off at the European factory of Siemens Rolling Stock and could be delivered to London immediately.

It was the first Underground locomotive to be delivered for the London Underground project.
