There was silence in the conference room for a while, and after a few minutes, when some of the people had finished reading the technical plan, a colonel stood up and began to speak first.

The colonel said: "Minister Liu, the technical plan proposes that we will develop this small channel than turbofan engine, the service life before the first maintenance is not less than 1500h, the total service life is not less than 15 years, according to the current situation of our domestic aviation industry, it is estimated that it is difficult to achieve, whether the requirements can be relaxed, such as the first turning life is not less than 1000 hours, the total service life is not 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: "What this comrade said is very right, everyone speaks freely. ”

Soon, a colonel stood up and said: "Minister Liu, our engine must have excellent reliability, and it must be clearly and even focused on in the technical plan. ”

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

The "Taihang" engine was originally intended to be used for the J-10 fighter, but there are many shortcomings in this engine, especially the lack of reliability, the J-10 power is single-engine, because the engine reliability is insufficient, no one dares to take this risk, so our J-10 is not installed in a large area with the Taihang engine, but on the double-engine J-11 fighter.

Even, the engines of the fighters exported by China to foreign countries are rarely equipped with domestic engines, but are mostly Russian-made engines or engines imported from Europe and the United States, because the reliability of such engines is higher than that of the "Taihang" engine.

Minister Liu said: "The speeches of the two comrades just now are very good, everyone can speak freely, do not have any scruples. It doesn't matter if it's wrong. ”

As soon as Minister Liu said this, everyone really spoke enthusiastically, collected a lot of opinions and suggestions, and several minutes takers who participated in the meeting recorded all these things one by one.

Zhang Haiping also stood up and put forward his own clear point of view: "Comrades. This is a new type of small channel ratio turbofan engine that we are about to develop, although it is only used as the power of J-10 or J-11, but to make technical preparations 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 comprehensively surpass the American F100 engine and the Russian AL-31F engine, not only to have good comprehensive performance. High reliability and safety, but also excellent take-off performance at altitude airports, and excellent high-altitude and high-speed performance......"

Zhang Haiping's speech was relatively long, and he even took out the American F100 engine and the Russian AL-31F engine as a comparison. These two engines, everyone naturally knows.

The F100 engine in the United States is mainly powered by the F-15 and F-16 fighters in the United States, and the F100 engine is the first military engine in the world to be put into use with a thrust-to-weight ratio of 8. The Russian AL-31F engine is powered by the Su-27. It is also the driving force of the current J-10 fighter.

There are many people who support Zhang Haiping's view, but there are also opponents. This part of the opponents, mainly because of their lack of confidence in the level of the domestic aviation industry, believes that the starting point of the engine is too high, and the difficulty of development will increase sharply, which may lead to the failure of development.

The colonel who was the first to speak at the meeting objected unequivocally: "Director Zhang, I think. According to the current situation of our domestic aviation industry, the starting point of this engine is too high, it may be difficult to develop successfully, even our "Taihang" engine, it has been after years of hard research and development to have its current appearance. I don't think it would be appropriate for such an engine to comprehensively surpass the American F100 engine and the Russian AL-31F engine. ”

There were not a few people who supported the colonel's views, and they nodded their heads.

However, Zhang Haiping also has a lot of supporters, even including a major general, the major general immediately said: "We can't be so pessimistic about the problem, we must have full confidence in our aviation industry, I think Tianfeng Technology Company is good, they have the strength to successfully develop the fourth generation of large channel ratio turbofan engine, I believe there is no problem in developing such a small channel ratio turbofan engine." ”

The colonel retorted: "Chief, the large channel ratio turbofan engine is mainly low-speed flight, focusing on low fuel consumption, low noise, and low emissions, while the small channel ratio turbofan engine, focusing on high-altitude and high-speed performance, the two are completely different, even if it is Tianfeng Technology Company, they can successfully develop the fourth-generation large channel ratio turbofan engine, but they may not be able to successfully develop the small channel ratio turbofan engine we need." ”

During the meeting, the controversy was very warm, because it was a free speech, and everyone was also on the matter, and did not engage in personal attacks, although there was controversy, but there was no such tense atmosphere.

The meeting lasted for several hours, and finally, Minister Liu made a concluding speech, and Minister Liu personally set the tone, which is basically the same as Zhang Haiping's point of view, this small signal ratio turbofan engine that is about to be developed must comprehensively surpass the American F100 engine and the Russian AL-31F engine.

Finally, Minister Liu said: "Today is the sixth of January, and the development project of our new engine is tentatively codenamed '106 Project'. ”

Project code 106!

Many people quietly glanced at each other, 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.

The current Tianfeng Technology Company can be said to have sufficient funds, and the construction of the Qingshi manufacturing base is naturally progressing rapidly, and even Li Tianfeng has begun to consider the procurement of equipment.

Because the planning has been done well before the construction of the base, what equipment is needed has basically been determined, and the procurement of equipment has also begun.

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

Li Tianfeng was in the office, looking at a long list of equipment, this is the list of equipment proposed by the process technology part, which has been fully demonstrated and discussed, and finally sent to Li Tianfeng, signed by Li Tianfeng.

The Qingshi manufacturing base mainly produces and manufactures turboshaft aero engines, such as the current turboshaft D and turboshaft E engines, and in the future, if a new type of turboshaft engine is developed, it will also be produced and manufactured in the Qingshi manufacturing base.

At present, the headquarters of Tianfeng Technology Co., Ltd. mainly specializes in the production and manufacture of turbofan engines, such as the current turbo 16 engine, turbofan 17 engine, and "TFWS003" turbofan engine, and in the future, it may also produce small channel ratio turbofan engines.

Now Tianfeng Technology Co., Ltd., more than 15,000 or 6,000 employees, the company covers an area of more than 2,000 acres, the construction of Qingshi manufacturing base has been completed, the company area has doubled, and the company's employees will definitely reach more than 20,000 people, and the follow-up may slowly reach 30,000 people, or even more than 30,000 people.

The list of equipment is very long, the total value of equipment is more than 300 billion yuan, if it is an ordinary leader, you may be dizzy when you see such a detailed list of equipment, but fortunately it is Li Tianfeng.

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

After taking a serious look, it took Li Tianfeng almost half a day's effort, this list of equipment is basically very comprehensive and scientific, Li Tianfeng only made a small change, deleted some unnecessary equipment, and added some equipment.

In the whole equipment list, there is no Japanese equipment, on the one hand, there is imported equipment from Europe and the United States can be purchased, there is no need to buy from Japan, on the other hand, mainly considering the high cost of repair and maintenance of Japanese equipment, Li Tianfeng directly abandoned Japanese equipment.

With a slight change and a sign of your name and opinion, the list of equipment will take effect and will soon enter the procurement process.

…………

After the Lunar New Year, not long after the new year went to work, Tianfeng Technology's "TFWS003" turbofan engine also completed a series of factory verification tests, and began to finalize the design.

The second and third prototypes of the "TFWS003" turbofan engine have also begun to be assembled, and after the assembly is completed, a series of comprehensive flight verifications will be carried out after factory test runs.

The aircraft for validation has already been selected, an Embraer regional airliner, a 37-seat ERJ135 regional airliner.

Embraer's commercial jets are divided into two series: the ERJ145 jet series - a total of four models, namely the 50-seat ERJ145, the 50-seat ERJ145 long-range, the 44-seat ERJ140 and the 37-seat ERJ135, all of which can use "TFWS003" turbofan engines.

In addition to the ERJ145 jet series, there is also the E-jet series, which is also four models, namely the E-170 with 70-80 seats, the E-175 with 78-88 seats, the E-190 with 98-114 seats and the E-195 with 108-122 seats.

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

Li Tianfeng attaches great importance to the cooperation with Embraer, and has a special office of Tianfeng Technology in Brazil, and now, the two sides are in the honeymoon period, and the cooperation has begun to deepen.
