At this moment, Yi Chunhua was slightly excited.

From the trial production of the first part of the engine, to the assembly of this engine, to the test run of the engine on the platform, everything is vivid.

After so much hard work, the first phased results were finally achieved, and the engine finally successfully completed the 150-hour long-term test run. This is a milestone for the newly developed aero engine, and it is very close to its final success.

"Chief Engineer Yi, we successfully completed the 150-hour long-term test run!"

"It's like a dream, it's unbelievable!"

"The whole process went so smoothly!"

In addition to the surprise on the faces of several key technicians next to them, they also had a feeling of unreality. In their minds, the 150-hour long test could be so smooth for the first time.

The key is that the engine performed perfectly throughout the entire test run.

They are engaged in the research and development and manufacturing of aero engines not for a year or two, but for more than ten or even twenty years. In their memory, the development and trial production of each new engine is often very bumpy and difficult.

In the process of development, there are always bumps and bumps, and there are constant problems of size. The first demonstrator will have various problems during the commissioning process, and then improve and design for these problems.

What about this engine?

It didn't have any problems at all, and the whole test process was excellent. A lot of key technicians thought to themselves, oh my God, this is the first engine.

Yi Chunhua was immersed in deep joy.

The 150-hour long-term test was successfully completed, and after he came back to his senses, he picked up his mobile phone and immediately called out, reporting the good news to Yu Shaoguang, the leader of the 336 factory.

"Mr. Yu, our 150-hour long-term test run was successfully completed, and the test data were very perfect, which was unbelievable. ”

"Lao Yi, is this successfully completed?"

Yu Shaoguang is not in Factory 336, but on a business trip in Beijing. Otherwise, he would have stayed in the test shop and watched the engine complete a long 150-hour test run.

Yi Chunhua said loudly: "Mr. Yu, it has been successfully completed!"

"Okay, great. Yu Shaoguang's tone was full of joy, which seemed to be able to pass through the phone, and Yi Chunhua seemed to be able to feel it thousands of miles away.

Yi Chunhua said: "Mr. Yu, after the successful completion of the 150-hour long-term test, we will start to prepare for the 300-hour long-term test, in addition, the manufacture of the second engine I think can be appropriately accelerated process, and strive to enter the general assembly of the second engine after the Spring Festival." ”

Assembly of the second engine was originally planned to begin around March 2004. Since the performance of the first engine is very good, it means that the design of the engine is very mature and perfect, and there will be no major changes or changes in the design in the future, which can completely speed up the assembly of the second engine.

Yu Shaoguang was very happy, and agreed in one mouthful: "Agreed to conduct a 300-hour long test, and the assembly of the second engine should also be put on the agenda, do you know, I went to visit Director Zhang today, and learned from Director Zhang that Jiuzhou UAV Company has begun the production and manufacturing of parts for the second aircraft, and the general assembly of the first UAV will begin in about a month." ”

Yi Chunhua said: "Their progress is really fast, and the final assembly of the first drone will begin in a little more than a month, which means that they will need the engine of the drone in two or three months at most." ”

Yu Shaoguang said: "Yes, in two or three months at most, people will definitely need two engines." ”

According to the assembly process of the UAV, the assembly of the fuselage is generally carried out first, and then the assembly of the avionics system and all related accessories, and the engine is generally assembled at the end.

But even if the engine is installed at the end, with the production process of Jiuzhou UAV Company, the engine should be needed for assembly in another two or three months.

After making this call, Yi Chunhua's whole person was like clockwork, and he devoted himself to his work. The engine will be tested for 300 hours after 150 hours of long testing.

The production and manufacturing progress of the parts of the second and third engines will be accelerated, and the assembly of the engines will begin after the Spring Festival, and the delivery will be made to Jiuzhou UAV Company in two or three months.

……

Time flies.

The Spring Festival is approaching, and in two days it will be the traditional Chinese New Year. Jiuzhou Industrial Group also officially closed for holidays from today, and employees only came to work on the eighth day of the first month.

This year's Lunar New Year, Tang Fei is preparing to go back to Qingjiang City for the New Year, while Li Xueyan has been in Qingjiang City, carefully taken care of by Xiao Meilan and Liu Ping, and her belly is also slightly bulging.

Accompanied by Xu Guangming, Tang Fei got on the train from Changzhou Railway Station at more than ten o'clock in the morning and bought a sleeper ticket for the EMU.

It's Spring Festival.

The entire train station in Changzhou City is crowded with people. However, Tang Fei had already booked the sleeper ticket for the EMU, and successfully got on the EMU he was going to take accompanied by Xu Guangming.

"Boss, there are so many people. ”

After getting in the car, Xu Guangming said like this.

Before Tang Fei could say anything, a middle-aged man from the bunk next to him immediately took over, "This year's Beijing-long line is quite good, I heard that a total of more than a dozen EMUs have been put into operation, which has greatly relieved the passenger pressure on this line." ”

Tang Fei smiled, and chatted with the middle-aged man while he hadn't driven yet, "Big brother, you are going home for the New Year." ”

"Yes. The middle-aged man nodded and said: "I work in Changzhou City, but my hometown is in HB Province, this train happens to pass by our door, fortunately it is an EMU, if it is an ordinary train, it will take more than 30 hours to arrive." ”

Hearing this, Tang Fei felt a strong sense of pride in his heart.

The EMU of Jiufang EMU Company was put into operation, which began to exert force for the Spring Festival transportation and brought convenience to the travel of the general public. Traveling on EMUs is much faster than regular trains.

It didn't take long for the EMU to start.

Sitting on the car, watching the buildings and trees outside regress rapidly, Tang Fei thought to himself, the running speed of the JF200A EMU is really fast and smooth.

Throughout December, Jiufang EMU completed the delivery of 4 JF200A EMUs, and also completed the delivery of 4 trains in January, which is basically stable at about 4 trains per month.

More than half of the orders for 32 trains have been delivered, and a total of 16 JF200A EMUs are speeding on the Beijing-long line. According to this production and manufacturing schedule, the delivery of all 32 trains will be completed in another three or four months.

In the afternoon, the EMU arrived at the Qingjiang Railway Station. Tang Fei got out of the car and waved his hand: "Guangming, see you after the Spring Festival, I wish you a good year in advance." ”

Xu Guangming hurriedly said: "Thank you, boss, we'll see you next year." ”

He had worked hard for a year, and he should have a good rest for a few days, Tang Fei simply gave Xu Guangming a holiday. Anyway, staying in Qingjiang City during the Spring Festival, he won't run around, and he doesn't need Xu Guangming to accompany him and protect his safety.

"Phineas!"

Walking out of the Qingjiang City Railway Station, as soon as she saw Tang Fei, Li Xueyan hurriedly shouted in surprise. Seeing his wife, Tang Fei walked over quickly.

Not only Li Xueyan came to the station to greet her, but her parents and parents-in-law came, and there were two cars parked not far away.

"Dad, Mom, you're all here. ”

The family is together, happy and happy, and the strong family affection seems to be indissolvable. Tang Xuewen and Liu Ping looked at their satisfied son, and their eyes were full of pride.

Li Weibin said: "Xiaofei, Jiuzhou Industrial Group has successfully become one of the world's top 500, congratulations." ”

Tang Fei hurriedly said: "Dad, it's just a small achievement, I want to work hard for a few years, and strive to make the scale of Jiuzhou Industrial Group go to a higher level and further rank in the world." ”

Li Weibin said: "Young and ambitious, this is a good thing, we all support you, Xueyan, you don't have to worry, feel at ease to focus on work." ”

Tang Fei took his wife's little hand and hurriedly thanked several elders.

The family also began to get on the train and leave the Qingjiang train station to go home.

Approaching the Lunar New Year, Qingjiang City already has a bit of a New Year's flavor.

……..

Thousands of miles away in London.

The land of China is immersed in the strong flavor of the New Year, and now it is the traditional festival of China, the Lunar New Year. In London, apart from Chinatown, you won't be able to experience the Lunar New Year in other places for the time being.

Christmas in the West has long passed, Londoners have begun to rush for life, a large number of citizens travel by the subway every day, some careful people find that it seems that there are more and more new subway locomotives.

……

Today's two shifts, the second shift is complete, thank you for your support.
