In his room, Li Tianfeng thought for a long time, and after thinking for a long time, Li Tianfeng thought in his heart, this is the new journey he is about to start.

At the same time, Li Tianfeng thought in his heart that he felt difficult for such an engine, and it was conceivable what kind of pressure the AVIC Group, which was developed at the same time as himself, was facing.

After the military held this meeting and obtained the top-secret technical documents and the development task book, the AVIC group returned to their headquarters and held a high-level meeting of the group company in the afternoon of the same day.

Li Tianfeng was right, the pressure on the part of AVIC Group is also huge, and at the meeting, many people even talked about this.

A vice president in a black suit said: "Mr. Lin, such a development task is simply unprecedented, even comparable to the pressure when we received the development task of the 'Emei' engine." ”

"Yes, Mr. Lin, the pressure is huge, and the key is that we don't have a suitable core machine, so we have to start all over again."

Mr. Lin looked around the entire conference room, and then said: "I also know that everyone is under a lot of pressure, how can I not, but we aviation people have always had a tradition of hard work and overcoming difficulties, and this time we must also carry forward this spirit." ”

After a slight pause, Mr. Lin continued: "Comrades, I have thought carefully, we are not without advantages, we at least have huge resources, many experts, whether it is scientific research, or manufacturing, we have complete facilities......

Mr. Lin listed a series of his own advantages at the meeting, and the participants felt a little less pressure in their hearts.

Soon, someone said: "Mr. Lin, as soon as you say this, my confidence is more sufficient, I suggest." Is it improved and upgraded on the basis of the Taihang engine? ”

Someone immediately agreed: "Mr. Lin, I think this plan is feasible, and it can be carefully demonstrated." ”

Mr. Lin said: "I think it is okay, in addition, we can also upgrade and improve on the basis of the AL-31F engine, and this plan can also be demonstrated." ”

in the conference room. The atmosphere gradually became lively, and many plans were proposed, but these plans must definitely be demonstrated, and the specific plan to adopt in the end has not yet been decided.

………

The largest shopping mall in Beijing.

Li Tianfeng was shopping, behind Li Tianfeng, he was following Wang Liang, the "coolie", today, Wang Liang was arrested by Li Tianfeng.

Who called Wang Liang, this kid is a local. Familiar with the environment and good driving skills, Li Tianfeng made a phone call, and Wang Liang immediately drove over and took Li Tianfeng to the largest and most prosperous shopping plaza in Beijing.

As for Sun Xiaoping and Liu Wei, they have already returned to Songzhou by plane this morning.

Wang Liang carried several shopping bags and followed behind Li Tianfeng. He said, "Brother-in-law, you buy so many things for my sister." Why don't you have one of me, no, I have to buy one thing. ”

Li Tianfeng smiled, looked at the big bags and small bags on Wang Liang's body, and couldn't help but smile, "Wang Liang." Your sister is now pregnant and needs special treatment. ”

Wang Liang said, "Brother-in-law, for the sake of me being a coolie for you, buy me one and compensate for it." ”

Li Tianfeng smiled and said, "Okay." For your sake, you can pick any one, but it can't be too expensive. ”

Hearing this, Wang Liang was overjoyed, and immediately said happily: "Brother-in-law, you are so good, I really love you to death, go, I'll take you there." ”

Saying that, Wang Liang suddenly became motivated, and Wang Liang, who was still following Li Tianfeng, listless and tired, immediately rushed to the front of Li Tianfeng, and took Li Tianfeng to the famous watch area very familiarly.

Seeing this, Li Tianfeng couldn't help but smile lightly, looking at it, Wang Liang, this kid, must have taken a fancy to a certain watch here for a long time.

Sure enough, Wang Liang rushed to the watch cabinet, pointed to a famous watch in the cabinet, and said loudly: "Brother-in-law, this is this watch, Belle Feida's latest model." ”

Li Tianfeng looked at this watch, his eyes lit up, Li Tianfeng also likes to wear watches, and there is an official Vacheron Constantin famous watch on his wrist, but when he looks at this watch, Li Tianfeng is also full of likes.

Li Tianfeng said happily: "Wang Liang, you can do it, good vision, this is the latest." ”

The shopping guide next to her saw that Li Tianfeng was extraordinary, and she was carrying a famous watch in her hand, and knew that Li Tianfeng had a lot of purchasing power, so she couldn't help but say enthusiastically: "Sir, this is our latest model, which is very suitable for young successful people like you." ”

Wang Liang also said: "Brother-in-law, I have been looking at this watch for a long time, and I noticed it as soon as it was placed on this counter, but I have not had enough money and my hand is relatively tight, brother-in-law, this time it depends on you." ”

Li Tianfeng smiled and said, "Yes, but I have to call you in the future." ”

Wang Liang hurriedly said happily: "Okay, okay, there is no problem." ”

Li Tianfeng said to the shopping guide: "Beauty, give me two pieces of this watch!" ”

Two watches!

Wang Liang looked at Li Tianfeng in surprise, the shopping guide lady was also stunned, and then, bursts of surprise, without thinking, Li Tianfeng bought two watches at one time.

Li Tianfeng saw Wang Liang looking at him in astonishment, Li Tianfeng smiled and said: "Liangzi, I also fell in love with this watch, you have a good eye." ”

Wang Liang came back to his senses and was pleasantly surprised, "Brother-in-law, you are so bold, you buy two watches at one time, but I like it!" ”

Li Tianfeng smiled proudly, "According to your brother-in-law's current financial resources, such two tables are naturally a piece of cake." ”

Wang Liang had a flattering expression, and came up and said, "Brother-in-law, I have taken a fancy to a Bentley, let's go, let's buy it." ”

Li Tianfeng scolded with a smile: "You kid owe a beating." As he spoke, Li Tianfeng flew up with a smile, and Wang Liang immediately ran away with a smile.

………

Li Tianfeng returned to Songzhou two days later and bought a lot of gifts for Wang Ruobing and his parents, and everyone was very happy.

After returning home in the morning, Li Tianfeng went to Tianfeng Technology Company in the afternoon, and Li Tianfeng began to draw up the design outline of the turbofan 20 engine in person.

What the military gave itself was only the technical requirements for the turbofan 20 engine, not the technical outline, and the design technical outline of the engine were completely different things, and Li Tianfeng had to draw up a detailed design technical outline on the basis of this technical requirement.

Previously, whether it was turboshaft D, turboshaft E, or turbofan 16, turbofan 17 and turbofan 18 engines, Li Tianfeng personally drew up the design technical outline.

What kind of design to use, what kind of parameters, how to ensure the high reliability and maintainability of the engine, Li Tianfeng also basically thought about it in his heart, and knew what kind of design technology to use.

First of all, it can only be regarded as a draft, and it will take Li Tianfeng several days to draw up such a draft, and then some details will have to be carefully scrutinized.

Li Tianfeng was "working hard" in his office, Xu Lilong knocked on the door and came in, Xu Lilong's face was happy, and he knew at a glance that Xu Lilong must have something good to report to Li Tianfeng.

Li Tianfeng looked up, saw Xu Lilong's happy face, and his heart was also happy, and hurriedly said, "Mr. Xu, please take a seat." ”

Xu Lilong sat down as he said, and then reported: "Mr. Li, I have two good news to report to you. ”

"Oh." Li Tianfeng was also happy, he didn't think about it or two good news, and suddenly, Li Tianfeng was also interested, and said happily: "Mr. Xu, two good news?" ”

Xu Lilong said: "Boss, two good news, the first news is that our Canadian office just called, our turbofan 17 engine has been installed on a Bombardier regional airliner, ready to start a series of comprehensive verification test flights. ”

Hearing this, Li Tianfeng was overjoyed, he didn't expect things to go so smoothly, as long as the other party installed his own turbofan 17 engine for test flight, he was sure that the other party would definitely place an order with him.

In Li Tianfeng's view, the turbofan 17 engine is really an excellent turbofan engine with a large channel ratio, and it is almost the first choice for regional airliners.

For example, this engine, low fuel consumption, low noise, low emission, high reliability and maintenance, it is almost impossible for Bombardier not to buy its own engine, the key is how much the other party is ready to buy, and how much can it account for Bombardier's share of the engine purchased.

Li Tianfeng thought in his heart, an excellent engine, its design technical outline is very important, if it was not for the original excellent design technical outline, there would not be this excellent engine.

It seems that the formulation of the technical outline must be carefully and fully considered, especially highlighting the high-altitude and high-speed performance, ultra-high reliability, and super maintainability.

Li Tianfeng said: "Mr. Xu, this is great news, pay close attention to Bombardier, pay close attention to the comprehensive flight test verification of our turbofan 17 engine. ”

Xu Lilong said happily: "Boss, don't worry, I will pay close attention to it personally." ”

Li Tianfeng nodded, and then said, "Mr. Xu, what about the second good news?" ”

Xu Lilong patted his head lightly and said with a smile: "Boss, you see that I am so happy that I almost forgot to report the second good news." ”

Seeing Xu Lilong's appearance, Li Tianfeng smiled happily and waited for Xu Lilong to continue.

Xu Lilong immediately said: "Boss, the second news is even more exciting, I have heard before, several domestic airlines have gone to Brazil to order regional airliners, and pointed out that these regional airliners must be equipped with our engines, I have always thought it was a rumor, and now it seems to be true." ”

Li Tianfeng said happily: "Mr. Xu, there is such a thing, if this is the case, it is a huge affirmation of our engine." ”

Xu Lilong nodded, and then said: "Boss, the second good news, Embraer has officially sent a letter, their vice president Mr. Marceldo will come to our company for an inspection, I guess if it is correct, it must be a business visit, and the purpose of the inspection is to prepare to order engines from us again." ”
