The 10 billion order made the employees of Tianfeng Technology happy for several days. Even several military representatives stationed in Tianfeng Technology Company, led by Chen Dong, went to Li Tianfeng's office to congratulate him. Chen Dong was also happy!

The better Tianfeng Technology develops, the higher its status will be. In the past, when Chen Dong was the military representative at the e-factory major, he was promoted to Tianfeng Technology Company after coming to Tianfeng Technology Company. Now he is a lieutenant colonel. If Tianfeng Technology Company continues with this development momentum, in a few years, he may be a colonel, or even a major colonel.

Chen Dong congratulated him, Li Tianfeng was also very happy, and chatted with Chen Dong for a long time with warm and politeness. Finally, Chen Dong left Li Tianfeng's office with a smile.

After returning from Beijing and bringing such a ten-billion order, Li Tianfeng became more full and devoted himself to his work with great enthusiasm.

The military is also very efficient. A few days later, green military trucks drove into Tianfeng Technology Company and transported one turboshaft D engine in the large warehouse in the test workshop factory area. These engines will be transported to the helicopter manufacturing plant.

The 3000-hour life test run has been carried out. The 2000-hour life test run has been completed before, and 1,000 hours of subsequent test runs will be added, with a total of 3,000 hours of life test runs. The subsequent 1,000-hour test runs are now coming to an end.

In the test run monitoring control room, the engine is being tested. The test run commander looked at the cumulative time of the test run, which has reached 3,000 hours of cumulative life. Qiu Wen'an was looking at the instruments and meters on the test run console and various data.

The oil consumption is normal!

Fuel consumption is normal!

The engine output power is normal!

The engine vibrates normally!

...

After a series of data and engine test drive status, everything is normal. That is to say, after the engine has a total of 3,000 hours of life, the engine status is still very normal, and the test drive can be continued.

Qiu Wen'an waved his hand and signaled to continue the test drive without stopping. The purpose is to test that the engine will work until abnormal and cannot continue to work normally, thereby determining the maximum service life.

Such a test run is also called a maximum life test run, or a disruptive test run. After completing such a test run, the engine will complete its mission.

At the test run site, Qiu Wen'an personally witnessed the successful completion of the 3,000-hour life test run of the turboshaft D engine. This was the task assigned by Li Tianfeng to Qiu Wen'an, while Li Tianfeng himself was in the office looking at the design drawings.

Out of trust and confidence in the turboshaft D engine, Li Tianfeng did not go to the test drive site. In Li Tianfeng's opinion, his engine will definitely be able to successfully complete the 3,000-hour life test drive.

3000-hour lifespan test drive! This is a very amazing result. Although Li Tianfeng did not come in person, Qiu Wen'an was slightly excited.

In the test drive monitoring and control room, everyone witnessed the engine on the test drive table completing a 3,000-hour life test drive. Everyone was excited and happy.

Several test runners stood up immediately. The joy and excitement on their faces were beyond words, and the test runners present cheered even more, and some of them even hugged each other tightly with excitement.

As technicians, everyone naturally knows the value of successfully completing the 3,000-hour life test drive, no wonder everyone is so excited.

Exaggeratedly, a test drive technician ran to Qiu Wen'an, grabbed Qiu Wen'an's hand tightly, and shouted happily: "Mr. Qiu, we successfully passed the 3,000-hour life test drive, and we successfully passed!"

In addition, Qiu Wen'an, the chief designer who has always been introverted and does not like words, also looked excited on his face. While excited, Qiu Wen'an applauded vigorously.

Under Qiu Wen'an's leadership, everyone applauded vigorously. A long-lasting applause sounded in the entire monitoring and control room. 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 sound of firecrackers was very loud and very cheerful. Two red and long firecrackers were lined up on the ground and dancing happily.

Successfully completed the 3000-hour life test drive!

This great news soon spread throughout the test workshop. Not long after, it spread from the test workshop to the entire Tianfeng Technology Company.

A military-green military truck was driving in from outside. Several soldiers in the car saw the big red firecrackers on the ground at the door of the test workshop and couldn't help but say to a security guard at the door: "Comrade, what's wrong? Are you happy?"

The security guard said proudly, happy, and loudly: "Our turboshaft D engine has just passed the 3,000-hour life test drive, and we set off firecrackers to celebrate."

3000-hour life test drive!

Everyone was slightly shocked by the soldiers on this military truck. They had been dealing with aircraft engines all year round. Everyone knew what it meant to successfully complete the 3,000-hour life test run. In addition to being shocked, one of the soldiers said: "You are so amazing!"

Upon hearing this, the security guard felt happy and a sense of pride rose from the bottom of his heart and instantly rushed to the sky. This sense of pride made the whole person tremble slightly.

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

This is the design result of Tianfeng Technology's Aero Engine Design Institute over the past few months. The design has been basically completed. The complete set of design drawings have been summarized here with Li Tianfeng. In the past few days, Li Tianfeng will sit in front of his computer when he has time, carefully and carefully looking at these drawings.

This is the design drawing of a new turbine shaft engine. This is a general-purpose turbine shaft engine. It is based on the core engine of the "tfwz001" type turbine shaft engine. It is designed on this basis, and this turbine shaft engine is provided.

After the design and shape of the turboshaft D engine, this design work has been started. This engine is aimed at the transportation helicopter market and foreign export markets.

The core engine part uses a "tfwz001" type turboshaft engine, and the remaining engine components are redesigned. The engine output power is 1500kw, and the engine weight is slightly lighter than the turboshaft d. It weighs less than 200 kilograms, and the work-to-weight ratio is barely nine.

Such an engine has a slightly worse technical level than the turboshaft d, but is much more advanced than the turboshaft c. Such an engine, internationally, is definitely a first-class turboshaft engine and has a wide range of uses.

Armed helicopters can be used, general-purpose helicopters can be used, and military and civilian transport helicopters can also be used. Their versatility is much larger than that of the turboshaft d, and they can target foreign markets as export-oriented products.

Such an engine is considered a transitional model of Tianfeng Technology. Before the development of more advanced aircraft engines, it was just right to develop such a transitional turbine shaft engine.

Because the core engine part is the same as the turboshaft D engine, it saves a lot of work and can greatly shorten the R&D cycle. Just a few months have basically completed all the designs, and most of the design drawings have been sent to Li Tianfeng.

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

Products from Tianfeng Technology must be a top-notch product!

Li Tianfeng will carefully check some more important parts, record some existing problems one by one, and then ask designers to make design improvements. He will fully consider many comprehensive factors such as the processability and cost of the parts.

Just as he read a few drawings, Li Tianfeng's phone rang. As soon as the phone was heard, Qiu Wen'an's voice came over.

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

Li Tianfeng said: "Mr. Qiu, the 3,000-hour life test run was successfully completed."

Qiu Wen'andao: "Yes, yes, we successfully completed the 3,000-hour life test drive. Now, we will continue to carry out the maximum life test drive."

Upon hearing this, Li Tianfeng felt a sense of joy. As he expected, the engine successfully completed a 3,000-hour life test drive. This shows that the performance of this engine is indeed excellent, with a first-round life of at least 3,000 hours. After that, after each overhaul, it can be used for another 3,000 hours, and three overhauls in total, and the overall life of the engine will reach a gratifying 12,000 hours.

12,000 hours!

This is definitely an important symbol of an excellent aircraft engine. If you cannot achieve such a life span, no matter how well the engine is designed, a short-lived engine, how can you talk about excellent design or first-class quality?

Li Tianfeng was also very happy. Even though he had long expected that his engine would be able to successfully test drive for 3,000 hours, but after he passed it smoothly and heard Qiu Wen'an's report, Li Tianfeng felt happy and comfortable in his heart.

The front page of Songzhou Daily, the red title, and the color photos of the turboshaft D engine, attracted the attention of many citizens.

The title of "Warm Congratulations to the Turboshaft D engine for successfully completing the 3,000-hour life test run" is very eye-catching. The report is full of pictures and texts. Seeing the enthusiastic reports, many people in Songzhou City gave thumbs up when talking about Tianfeng Technology Company.

At e Factory, when everyone heard this news, they knew the value of the 3,000-hour life test drive. Everyone admired Tianfeng Technology Company so much that they were envious. In addition to admiring it, they felt even more envious.
