The tens of billions of orders have made the employees of Tianfeng Technology happy for several days, that is, several military representatives in Tianfeng Technology Company, under the leadership of Chen Dong, went to Li Tianfeng's office to congratulate them, and Chen Dong was also happy in his heart!

The better the development of Tianfeng Technology, the higher his status will be, in the past, Chen Dong was a major when he was a military representative in the E factory, and he was promoted to a level after coming to Tianfeng Technology Company, and now he is a lieutenant colonel, if Tianfeng Technology Company continues to develop like this, in a few years, he may be a colonel, and he may even be promoted to a colonel.

Chen Dong congratulated, Li Tianfeng was also very happy, and chatted with Chen Dong warmly and politely for a long time, and finally, Chen Dong left Li Tianfeng's office with a smile.

After returning from the capital and bringing such a 10 billion order, Li Tianfeng was even more full and energetic to work.

The military was also very efficient, and a few days later, green military trucks drove into Tianfeng Technology and transported turboshaft D engines from the large warehouse in the test workshop to the helicopter factory.

The 3000-hour life test has been carried out, the 2000-hour life test has been carried out in the front, and the follow-up test has been added for another 1000 hours, with a total of 3000 hours of life test, and the subsequent increase of the 1000-hour test is now nearing the end.

In the test monitoring and control room, the engine is being tested, and the test commander looks at the cumulative time of the test run, which has reached 3000 hours of cumulative life test, and Qiu Wenan is looking at the instruments and meters on the test control platform, looking at the number of items.

Lubricating oil consumption is normal!

Fuel consumption is normal!

The engine output is normal!

The engine vibrates normally!

……

A series of numbers and engine test states look down, a qiē normal, that is, this engine after a cumulative 3000 hours of life test. The engine is still in good condition and can continue with the test run.

Qiu Wenan waved his hand and signaled to continue the test run without stopping, the purpose of which was to test that the engine worked until there was an abnormality. can no longer work properly to determine what the maximum service life is.

Such a test run, also called the maximum life test, or the destruction test, to complete such a test, this engine will also complete its mission.

At the test site, Qiu Wenan personally witnessed the successful completion of the 3000-hour life test of the turboshaft D engine, which was the task assigned by Li Tianfeng to Qiu Wenan, and Li Tianfeng himself was in the office. Look at the design drawings one by one.

Out of trust and confidence in the turboshaft D engine, Li Tianfeng did not go to the test site, in Li Tianfeng's opinion, his engine will definitely be able to complete the 3000-hour life test.

3000 hours life test! This is a very remarkable achievement, although Li Tianfeng did not come in person, Qiu Wenan's heart was slightly excited.

In the test monitoring and control room, everyone witnessed the completion of the 3,000-hour life test of the engine on the test bench, and everyone's hearts were not excited. Not to be pleased.

Several test drivers immediately stood up. The joy and excitement on his face were beyond words, and several test technicians present cheered even more, and even two of them hugged each other tightly with excitement.

As a technician, everyone naturally knows the gold content of completing the 3,000-hour life test, no wonder. Everyone is so excited.

Exaggeratedly, a test technician ran to Qiu Wen'an's face, grabbed Qiu Wen'an's hand tightly, and said loudly. shouted happily: "Mr. Qiu, we have a 3000-hour life test, and we have a good time!" ”

Even Qiu Wen'an, the chief designer who has always been more introverted and doesn't like words, also looked excited, and at the same time excited, Qiu Wenan applauded vigorously.

Under the leadership of Qiu Wen'an, everyone applauded vigorously, and there was a long-lasting applause in the entire monitoring and control room, and the excitement and joy in everyone's hearts were all contained in this long-lasting applause.

Outside the gate of the test workshop, the crackling firecrackers were very loud and cheerful, and the two red and long firecrackers were lined up on the ground and danced happily.

Shun lì completed the 3000-hour life test!

This good news soon spread throughout the test workshop, and it didn't take long for it to spread from the test workshop to the entire Tianfeng Technology Company.

An army-green military truck was driving in from outside, and several soldiers on the car saw the big red firecracker crumbs at the entrance of the test workshop, and couldn't help but say to a security guard at the door: "Comrade, what's the matter, you have a happy event?" ”

The security guard was proud, happy, and said in a very loud voice: "Our turboshaft D engine has just been tested for 3,000 hours, and we set off firecrackers to celebrate." ”

3000 hours life test!

Several soldiers on this military truck, everyone was slightly stunned, dealing with aero engines all year round, everyone knows what it means to complete the 3,000-hour life test run, and in addition to being stunned, one of the soldiers said: "You guys are amazing!" ”

Hearing this, the security guard was happy in his heart, and a sense of pride rose from the bottom of his heart, and he instantly rushed straight to the Tianling Gai, such a sense of pride made the whole person tremble slightly.

………

Li Tianfeng looked at the design drawings one by one on the computer in the office, looked at them very carefully, and from time to time, he also recorded some problems and improvements in his notebook.

This is the design results of the aero engine design institute of Tianfeng Technology Company in the past few months, the design is basically completed, and the complete set of design drawings are all summarized to Li Tianfeng here, these days, Li Tianfeng will sit in front of his computer when he is free, carefully and carefully, and read these drawings seriously.

This is the blueprint of a new turboshaft engine, which is a general-purpose turboshaft engine, based on the core engine of the "TFWZ001" turboshaft engine, and on this basis, this turboshaft engine is designed.

Work has already begun on the design of the turboshaft D engine, which is aimed at the transport helicopter market as well as export markets abroad.

The core part of the engine adopts the "TFWZ001" type turboshaft engine, and the rest of the engine components are redesigned, the engine output is 1500KW, and the engine weight is slightly lighter than the turboshaft D, less than 200 kilograms, and the power-to-weight ratio barely reaches nine.

Such an engine, the technical grade is slightly worse than the turboshaft D, but much more advanced than the turboshaft C, such an engine, in the world, is definitely a first-class turboshaft engine, and a wide range of uses.

Armed helicopters can be used, general-purpose helicopters can be used, military and civilian transport helicopters can also be used, the versatility is much greater than the vortex D, and can be aimed at foreign markets, as an export-oriented product.

Such an engine can be regarded as a transitional model of Tianfeng Technology, and it is just right to develop such a transitional turboshaft engine before there is no more advanced aero engine research and development plan.

Because the core part of the engine is the same as the turboshaft D engine, this saves a large part of the workload and can greatly shorten the research and development cycle.

Li Tianfeng will not relax the research and development of this engine because this engine is a transitional model, on the contrary, Li Tianfeng attaches great importance to it.

Produced by Tianfeng Technology, it must be a high-quality product!

For some of the more important parts, Li Tianfeng will carefully check them, record some problems one by one, and then ask the designers to make design improvements. And fully consider the manufacturability of parts, cost and many other comprehensive factors.

Just as he was reading a few drawings, Li Tianfeng's phone rang, and as soon as the phone rang, Qiu Wenan's voice came.

Qiu Wen'an said: "Boss, I want to report good news to you!" ”

Li Tianfeng said: "Mr. Qiu, Shun lì has completed the 3,000-hour life test. ”

Qiu Wen'an said: "Yes, yes, we have completed the 3,000-hour life test, and now, continue to carry out the maximum life test." ”

Hearing this, Li Tianfeng's heart was happy, as he expected, the engine completed the 3000-hour life test, which shows that the performance of this engine is indeed excellent, the life of the first turnover period can reach at least 3000 hours, and later, after each overhaul, it can be used for 3000 hours, a total of three overhauls, and the overall life of the engine will reach a gratifying 12000 hours.

12,000 hours!

This is definitely an important symbol of an excellent aero engine, it cannot reach such a life, no matter how well the engine is designed, a short-lived engine, how to talk about excellent design, how to talk about first-class quality.

Li Tianfeng was also very happy, even though he had long expected that his engine would reach 3,000 hours of life test, but when he really heard Qiu Wen'an's report, Li Tianfeng's heart was happy and comfortable.

The position on the front page of "Songzhou Daily", the red headline, and the color photo of the turboshaft D engine attracted the attention of many citizens at once.

"Warm congratulations on the completion of the 3000-hour life test run of the turboshaft D engine", the headline is very eye-catching, the report is full of pictures and texts, seeing the enthusiastic report, many people in Songzhou City, talking about Tianfeng Technology Company and giving a thumbs up.

In the E factory, everyone heard such news, knowing the gold content of the 3000-hour life test, everyone admired Tianfeng Technology Company to death, and in addition to admiration, they were envious in their hearts.
