The conference room was very quiet for a moment. After a few minutes, some people had read the technical plan. A large university stood up and began to speak first.

The colonel said: "Minister Liu, the technical plan proposes that the small-channel-based turbofan engine we are about to develop will have a service life of no less than 1500 hours before the first maintenance and a total service life of no less than 15 years. According to the current status of our domestic aviation industry, it is estimated that it will be difficult to achieve. Whether the requirements can be relaxed, such as the first life span is not less than 1,000 hours and a total service life of no less than 10 years."

In the conference room, many people looked at each other and nodded. Obviously, many people agreed with this.

Minister Liu said loudly: "This comrade is right, everyone speaks freely."

Soon, a colonel immediately stood up and spoke: "Minister Liu, our engine must have excellent reliability, and it must be clear and even focused in the technical solution."

Minister Liu nodded, obviously fully agreeing with this point and said to the relevant comrades: "This suggestion is very good and must be put forward as a key point in our technical solution."

The "Taihang" engine was originally intended for use in the J-10 fighter jet, but this engine has many shortcomings, especially its reliability. The J-10 power is a single-engine. Because the engine is not reliable enough, no one dares to take this risk. Therefore, our J-10 did not install the Taihang engine on a large scale, but was installed on the J-11 fighter jet with a double-engine.

Even the engines of fighter jets exported to foreign countries are rarely equipped with domestic engines, but are mostly made from Russian engines or imported from Europe and the United States, because such engines have higher reliability than "Taihang" engines.

Minister Liu said: "The speeches of the two comrades just now are very good. Everyone speaks freely and don't have any scruples. Even if they say it wrong, it doesn't matter."

After Minister Liu said this, everyone spoke enthusiastically, collected a lot of opinions and suggestions, and several meeting recorders who participated in the meeting recorded all of these things one by one.

Zhang Haiping also stood up and put forward his own clear point of view: "Comrades, this is a new small-channel turbofan engine that we are about to develop. Although it is only used as the power of J-10 or J-11. But to prepare for our more advanced turbofan engine in the future, I think its technical starting point must not be too low."

"On the contrary, this engine must have a relatively high technical starting point and must fully surpass the US F100 engine. The Al-31f engine surpasses Russia must not only have good comprehensive performance, high reliability and safety, but also excellent plateau airport takeoff performance and excellent high-altitude and high-speed performance..."

Zhang Haiping's speech was quite long, and even compared it with the US F100 engine and the Russian Al-31f engine. Everyone knows these two engines naturally.

The US f100 engine is mainly powered by the US fighter jets F-15 and F-16. The f100 engine is the first military engine to be put into use in the world with a thrust-weight ratio of 8. Russia's al-31f engine is powered by the Su-27. It is also the current J-10 fighter jet.

There are many people who support Zhang Haiping's view, but there are also opponents. These opponents are mainly not confident about the level of the domestic aviation industry, believing that the starting point of the engine is too high, and the difficulty of development will increase sharply, which may lead to development failure.

The colonel who was the first to speak at the meeting clearly opposed: "Director Zhang, I think that according to the current status of our domestic aviation industry, if this engine starts too high, it may be difficult to successfully develop. Even our "Taihang" engine at the beginning, it was only after years of hard development that it was the current situation. If such an engine surpasses the US f100 engine and the Russian al-31f engine, I think it is not suitable."

There are also many people who support the colonel's views, and these people nodded one after another.

However, Zhang Haiping has many supporters, even a major general. The major general immediately said: "We cannot be so pessimistic when looking at the problem. We must have sufficient confidence in our aviation industry. I think Tianfeng Technology is good. They have the strength to successfully develop the fourth-generation large-hauld-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bird-bi

The colonel retorted: "The chief, the turbofan engine of the big trolley is mainly for low-speed flight, with the focus on low fuel consumption, low noise, and low emissions, while the turbofan engine of the small trolley is focused on high-altitude and high-speed performance. The two are completely different. Even Tianfeng Technology Company can successfully develop the fourth generation of the big trolley is turbofan engine, but it may not necessarily successfully develop the small trolley is turbofan engine we need."

During the meeting, the controversy was very hot because they spoke freely, and everyone was just talking about the matter and did not engage in personal attacks. Although there was controversy, there was no such tense atmosphere.

The meeting lasted for several hours. Finally, Minister Liu made a summary speech. Minister Liu personally decided on the tone, which was basically consistent with Zhang Haiping's view that this small-channel turbofan engine that will be developed must completely surpass the US F100 engine and Russia's al-31f engine.

Finally, Minister Liu said: "Today is January 6th. The development project of our new engine is tentatively designated as '106 Project'."

Project code 106!

Many people looked at each other quietly, their eyes full of excitement!

Tianfeng Technology Company.

A few days ago, Li Tianfeng went to the Qingshi Manufacturing Base under construction and saw that the entire base was in full swing. After seeing it, Li Tianfeng was quite satisfied.

Tianfeng Technology Company is now well-funded, and the construction of Qingshi Manufacturing Base is naturally progressing very quickly. Li Tianfeng has even begun to consider equipment procurement matters.

Because the planning has been done before the base construction, the equipment needed has basically been determined, and the equipment procurement matters have also begun.

Equipment procurement is mainly based on imported equipment, plus a certain amount of domestic equipment, such as CNC lathes, various models, large and small CNC lathes, at least half of which will be imported from abroad, and about half will be purchased in mainland China or Taiwan.

In the office, Li Tianfeng was carefully looking at a long list of equipment. This was the list of equipment proposed in the process technology part. It had been fully demonstrated and discussed and finally sent to Li Tianfeng, and signed by Li Tianfeng to take effect.

Qingshi Manufacturing Base mainly produces turbine-shaft aircraft engines, such as the current turboshaft d and turboshaft e engines. In the future, if new turbine-shaft engines are developed, they will also be produced and manufactured at Qingshi Manufacturing Base.

The current headquarters of Tianfeng Technology Company mainly specializes in the production of turbofan engines, such as the current turbocharger 16 engine, turbofan 17 engine, and "tfws003" type turbofan engine. In the future, it may also produce small-channel turbofan engines.

Tianfeng Technology Company now has more than 15,000 employees and more than 6,000 employees, with an area of ​​more than 2,000 acres. The construction of the Qingshi Manufacturing Base has been completed and the company's area has doubled. The company's employees will definitely reach more than 20,000. In the future, it may gradually reach 30,000, or even more than 30,000.

The equipment list is very long, with a total value of more than 30 billion yuan. If you are an ordinary leader, you may feel dizzy when you see such a detailed equipment list. Fortunately, it is Li Tianfeng.

Li Tianfeng is very clear about technical matters and production and processing matters, so he naturally knows which equipment to purchase.

After reading it carefully, it took Li Tianfeng almost half a day to work. This equipment list is basically very comprehensive and scientific. Li Tianfeng only made a small change, deleted some unnecessary equipment, and added some equipment.

In the entire equipment list, there is no Japanese equipment. On the one hand, there are imported European and American equipment to be purchased, and there is no need to purchase it from Japan. On the other hand, it is mainly because of the high subsequent maintenance and maintenance costs of Japanese equipment, Li Tianfeng directly abandoned Japanese equipment.

If you make a slight change, sign your name and opinion, this equipment list will take effect and will soon enter the procurement process.

…………

After the Lunar New Year, not long after going to work in the new year, Tianfeng Technology's "tfws003" turbofan engine also completed a series of factory verification and test runs, and began to design and finalize the relevant application materials. Tianfeng Technology Company submitted it to the relevant superior departments.

The second and third and three or two prototypes of the "tfws003" type turbofan engine have also begun to be assembled. After the assembly is completed, a series of comprehensive flight verification will be carried out after factory trial operation.

The verified aircraft has been selected, a regional passenger aircraft from Embraer, and a 37-seat erj135 regional passenger aircraft.

Embraer's commercial jet aircraft is divided into two major series: the erj145 jet series, the 50-seat erj145 remote model, the 44-seat erj140 and the 37-seat erj135. These four aircraft can all use the "tfws003" turbofan engine.

In addition to the erj145 jet series, there are also four models, namely the 70-80-seat e-170, the 78-88-seat e-175, the 98-114-seat e-190, and the 108-122-seat e-195.

In addition, there are a number of business jets, including the Feihong 100, Feihong 300, Legacy 450, Legacy 500, Legacy 600, Legacy 650 and the hereditary 1000 jet business jets.

Li Tianfeng attaches great importance to cooperation with Embraer and has a special office of Tianfeng Technology in Brazil. Now, the two sides are in the honeymoon period and the cooperation is gradually deepening.
