"Success, success!"

"We had a successful first test run!!"

In the entire monitoring and control room, the atmosphere reached its peak, and everyone's kind of joy, excitement, and excitement were all expressed on their faces, and even through guò action tables came out.

Several test drivers, needless to say, shouted and jumped, excited and excited, and even, there were two test drivers hugging each other tightly, and one test driver, clenching his fists hard, bending over and roaring loudly with joy, that kind of excitement, the expression was vivid.

Li Tianfeng saw everyone like this, and his heart was also inexplicably excited, and the first test run of the first verification machine was a complete success, indicating that he had taken a solid step.

……

The news of the successful test run spread very quickly, and soon spread throughout Tianfeng Technology Company, hearing such exciting good news, every employee's face was filled with joy, as if the New Year was celebrated, and even more happy than the first day of work during the Spring Festival.

"The test was successful, you know!"

"I just knew, such good news, it's so exciting!"

"The test run was a complete success, our hard work for so long was completely worth it, I am so happy!"

“……”

The employees of Tianfeng Technology, hearing such good news, everyone was happy for a while, and the whole Tianfeng Technology Company was boiling, everyone rushed to tell each other, and even some employees were so excited that their eyes were slightly moist.

"Bang, Peng, Peng......"

In front of the main factory of Tianfeng Technology, dozens of barrels of ceremonial flowers were lined up, and several security guards were lighting fires, and a deafening sound of ceremonies pushed the atmosphere to the top.

Many of the employees of Tianfeng Technology ran out of the factory and out of the office. Looking happily at this delightful flower and hearing the earth-shattering sound of the flowers, everyone seemed to hear the best, most beautiful and most pleasant sound in the world.

"A little up, a little more. A little further to the right. ”

Several security guards are hanging a long huge banner above the factory gate, on the red banner, several white characters "Congratulations on the success of the first test run", these big words, very eye-catching, standing on Songzhou Avenue can also be seen clearly.

The test was a complete success, and Li Tianfeng's heart was extremely comfortable.

When I came back from the test workshop, I saw the majority of employees as if they were celebrating a holiday. Li Tianfeng smiled happily, on a day like today, there is no need to ask everyone to work hard, today should be a happy day, today is everyone's festival, and it is also the festival of Tianfeng Technology Company.

In the evening, Tianfeng Technology Company held a grand celebration banquet, with dozens of tables in the state-guest hotel. Such a big scene made even Chen Fatzi, the general manager of the State Guest Hotel, stunned.

Participation in banquets. In addition to the designers, process personnel, and management personnel above the supervisor of Tianfeng Technology, a lot of guests were also invited, and Zhang Haiping must have been invited to participate. Wei Jin, Guo Tongde, Zhu Maohua, Yang Xianfeng, Liu Qingshan, etc. were all invited over.

Li Tianfeng's friends, congratulated Li Tianfeng and Tianfeng Technology Company, such a grand and warm celebration banquet, Li Tianfeng was drunk. Happily drunk......

In the next day's "Songzhou Daily", in the position of the front page, a large number of pictures and texts were reported, "China's first fourth-generation turboshaft engine successfully completed the first verification test in Tianfeng Technology Company".

Such a report has attracted a large number of eyeballs within the scope of Songzhou City, and many citizens who are concerned about the aviation industry and national defense construction have been heated discussions for several days.

E factory, the heated discussion is unprecedented.

This is Li Tianfeng's original work unit, many people have known Li Tianfeng before, and even familiar with Li Tianfeng, at the same time, everyone is familiar with the current situation of the aviation industry, and is even more familiar with aero engines. Here, the heated discussion is even more lively.

All units, workshops, offices, and teams, the most talked about are Li Tianfeng, Tianfeng Technology, and this engine that has just completed the first verification test.

Even, many grass-roots and middle-level cadres in E factory could not help but have a heated discussion, no, after a meeting, several middle-level cadres who were not in a hurry to disperse were smoking cigarettes while chatting, and the content of the chat was Li Tianfeng and his engine.

"Li Tianfeng is amazing, such an engine can be made in just two or three years."

"Yes, when I first heard such news, I thought it was a rumor, but I didn't think it was true, people have completed the first verification test, amazing!"

"I'm really a little envious of Tianfeng Technology, and if I make such a bullish aero engine, I will definitely have to be coaxed."

"Yes, such an engine, how exciting!"

“…”

In Factory E, everyone is hotly discussed, and many people are envious for a while, wishing that they are a member of Tianfeng Technology and can share this proud achievement.

"Lao Bao is now developed, although it used to be a senior engineer in our department, but where is there such a style now, I happened to meet him yesterday, the whole person is completely different, full of red light, the pride exuded by the body, the spiritual momentum, and the previous is completely different."

"It's not, you know Xiao Jiang in our office, Tianfeng Technology, who jumped to Tianfeng Technology two years ago, happened to meet him today, good guy, driving a brand new off-road vehicle, I heard that he became the department manager of Tianfeng Technology, and he said a few words, and he opened and closed his mouth to 'How is our engine', tsk, I can't believe it, it was the former Xiao Jiang in our office."

Tianfeng Technology Company.

The first test run of the first demonstrator was a complete success, a grand celebration banquet was held that night, and the next day, the engine was transported from the test workshop back to the final assembly workshop, and then it was disassembled and disassembled into a parts state.

After the engine is disassembled, the individual parts will be strictly inspected, and after the test run, there will be any changes in each part and whether there is any problem.

If a problem is found, it is necessary to analyze and find out the cause, of course, it is impossible to have no problems, after the first verification test of the first verification machine, there will always be problems with some parts, the key is what type of problem, whether it is strict or not, whether the design or process needs to be improved.

The verification machine is used to verify the design, manufacturing and assembly process, materials and other aspects, and even, sometimes, to make a design improvement, or use a new material, the new process can also be tested and verified.

The disassembly of the aero engine is much faster than the assembly, the assembly of this engine took more than a week, but the disassembly took only one day, within one day, the assembly workshop successfully completed the task, and now, this engine has become a part state.

The parts are also carefully cleaned, cleaned with gasoline or other cleaning agents, and the parts are classified by parts and placed in different areas.

For example, the parts of the compressor part are neatly placed in one area, the parts of the combustion chamber part are placed in one area, and the parts of the turbine part are placed in one area.

The parts are placed according to the area, and cleaned cleanly, the inspection of each part has begun, the process technicians and inspectors of the assembly workshop have all started to work, the visual inspection of the parts, the size measurement, and even metallographic analysis if necessary.

Today, Li Tianfeng personally stayed in the assembly workshop, the first test run was completed, and a solid step was taken, but the work behind it can not be taken lightly, and it is very arduous, for example, after this test run, the inspection of parts is very critical.

A series of problems can often be seen from the parts after the commissioning, and it may be necessary to improve and refine the design according to these problems.

Li Tianfeng was wearing thin white gauze gloves, holding a magnifying glass, and was looking at the free turbine disc seriously. Part inspection, first of all, is the appearance of the inspection, that is, to see the surface appearance of the part.

Before the test, the turbine disc is the metallic luster of high-temperature alloy, very bright, after the test, after the test, experienced a high temperature of more than 1,000 degrees, and the surface color of the parts has changed slightly.

Li Tianfeng held a magnifying glass and looked very carefully, Li Tianfeng was judging whether the slight change in color was within the normal range, whether it caused a change in the structure of the material.

Not far from Li Tianfeng, Qiu Wenan was also personally in battle, also wearing white gloves and holding a magnifying glass, looking at a part seriously.

Li Tianfeng looked at it carefully for a long time, looked at this turbine disc once, and didn't even put every tenon groove over. After watching it for a long time, Li Tianfeng had a conclusion in his heart, this is a normal change, and it is completely within the normal range.

There are a lot of parts, such an inspection, at least a few days, or even more than ten days, if more problems are found, the time period will be longer.

………

Tianfeng Technology Co., Ltd. completed the first test run, and is inspecting the parts of the engine that has completed the test run.

"The first verification test was a complete success", the post is very detailed, and there is even a photo of the engine being tested on the test bench.

As soon as this post came out, it was like a bombshell, almost turning the forum upside down, and even some deep-water fish were blown up, and the whole forum was hot again.

In such forums, most of them are military enthusiasts, or military enthusiasts, and there are even many people in the industry, such as those in the aviation industry, some people in the military, etc., whose level is higher than that of those in the general forum.

The first validation test was successful, and everyone knows what that means.

Today's two watches, the first one is sent!

Came back late, the update was a little late, sorry! (To be continued......)
