The turbofan 18 engine is considered the first generation of the large-halogen-type turbofan engine of Tianfeng Technology. It has a thrust level of 10,000 pounds and a 50-70-seat regional passenger aircraft power.

Li Tianfeng plans to develop a better and better generation regional passenger aircraft power than the turbofan 18 engine based on the second-generation core aircraft.

There has always been a striking countdown on Tianfeng Technology's official website. At that time, Li Tianfeng promised to launch this excellent regional passenger aircraft power within three years. Now, with the design of the second-generation core aircraft completed to this level, we can completely consider the design of the next regional passenger aircraft.

This regional passenger aircraft is designed based on the second generation core aircraft of Tianfeng Technology Company. Compared with the turbofan 18 engine, it will be more fuel-efficient, more economical and more outstanding.

From early June to the end of June, for almost a month, Li Tianfeng not only paid attention to the design of his second-generation core engine, but also the design of this engine.

After almost a month, Li Tianfeng personally drafted this design technical outline. In early July, Li Tianfeng convened everyone to have a meeting at the Aero Engine R&D Center.

Those who can attend this conference are all the best people in the field of aviation engine research and development of Tianfeng Technology, the backbone of the backbone and the elite among the elite.

Tianfeng Technology's aviation engine research and development team does not include process technicians. The number of technical personnel of various types has reached a huge number of more than 5,000, reaching sixteen design rooms, as well as supporting test centers, materials engineering centers, electronic research centers, etc.

More than 5,000 people can sit here, only a few dozen people, and they are completely among the elites. With such a powerful R&D team under his command, and with his helm and pilot, Li Tianfeng is full of confidence.

Even if Li Tianfeng knew that if this engine was successfully developed, it would be the most advanced regional passenger aircraft power in the world, he was full of confidence.

The conference room was very quiet. Li Tianfeng was using a projector to explain the design technical outline he had prepared in detail, even including his own design ideas.

The overall engine design is as follows!

The fan is first-level, with a diameter of 1.3 meters, and a 5.2-channel ratio.

Compressor is sixth stage, high-pressure turbine is one stage, and low-pressure turbine is two stages.

Thrust-weight ratio 12. Maximum thrust force 12,000 pounds, fuel consumption...

Li Tianfeng introduced it in detail. This engine uses the second-generation core engine technology of Tianfeng Technology, and the thrust-to-weight ratio can be designed above 15. However, as a civilian large-haul channel turbofan engine, the thrust-to-weight ratio of 12 is already high enough.

For civilian large-haul engines, the thrust-to-weight ratio is not the most important. The most important thing is low fuel consumption, low emissions, low maintenance and use costs, high reliability, high life, etc.

Obviously, this upcoming engine fully adheres to this concept. As the design elite of Tianfeng Technology, everyone is very clear about the performance of the turbofan 18 engine, but this engine is much better than the turbofan 18 engine.

After Li Tianfeng's introduction, someone immediately said: "Mr. Li, once such an engine is developed, it will be the most outstanding regional passenger aircraft power in the world, no doubt about it."

Someone also said: "Mr. Li, the engine thrust range is 4,700 pounds to 12,000 pounds. It can be used as the power of 30,40-seater passenger aircraft or business aircraft, as well as the power of 50 to 100-seater regional passenger aircraft. It has a wide range of use. It can almost achieve full coverage of regional passenger aircraft engines."

Sun Xiaoping also said: "Boss, you have already planned. The second-generation core machine we are developing now has the design size and power level, which is tailor-made for this engine. It can be moved directly to use, and basically no need to change it."

Of course, at the beginning of the design of the second-generation core aircraft, Li Tianfeng made long-term plans. The design size of the second-generation core aircraft was considered in the future power of this regional passenger aircraft.

It can be moved directly to use, with a small size change, which will save a lot of trouble and greatly shorten the design and development time of this regional passenger aircraft engine.

Li Tianfeng said: "Mr. Sun, you are right. I considered the design of our engine at the beginning."

Then, Li Tianfeng said: "Although our regional passenger aircraft has core aircraft, there are many design and R&D difficulties. Now I will talk to you a little..."

Li Tianfeng talked about these difficulties one by one, and even emphasized that when design, it is necessary to consider low manufacturing costs, high quality and quality.

Then, Li Tianfeng looked around the entire conference room and after looking at everyone, Li Tianfeng said loudly: "Do you have the confidence to fully complete the design of this engine before the end of this year in half a year!"

“Have confidence!”

"No problem!"

Everyone's answers were very loud and powerful, and they seemed to be full of confidence. Everyone was confident in this way, mainly because the design of the second-generation core machine was completed and the design process was relatively smooth. In addition, what was more important was that Li Tianfeng, the leader.

Li Tianfeng introduced this design technical outline, and then everyone conducted a careful review, and many people also put forward good opinions and suggestions, and Li Tianfeng improved them one by one.

Li Tianfeng's view of the design technical outline after review, it has been very perfect and reasonable, and the design can be carried out on this basis.

A few days later, the design of this engine began, and the design was carried out based on the second-generation core engine.

At the same time, Li Tianfeng began to apply for the national project of this engine. Surprisingly, the project was very smooth. The engine was designed and the country had officially approved the project, and the engine code was turbofan 21.

Such rapidity shows the status and influence of Tianfeng Technology Company, and also shows the recognition of Tianfeng Technology Company by the upper level.

Although the turbofan 21 engine is just a civilian regional passenger aircraft engine, it is very advanced and outstanding, and has attracted the interest of many people, such as Zhang Haiping.

After reading the design technical outline, Zhang Haiping happily called: "Mr. Li, the turbofan 21 engine is very advanced and will definitely be very outstanding. Once such an engine is put into the market, I think many people should be depressed."

Li Tianfeng laughed, "Minister Zhang, it's still early. Now, the engine design work has just begun."

Zhang Haiping said: "Mr. Li, I believe your speed. At this time next year, you may have entered the full trial production of parts."

Li Tianfeng pointed it a little and agreed with this point. At this time next year, he will definitely enter the trial production stage. If the progress goes a little smoother, the assembly of the first prototype may have begun.

Li Tianfeng said: "Minister Zhang, you didn't think you are so concerned about our turbofan 21 engine, your drone project, how about you?"

Speaking of the drone project, Zhang Haiping could only sigh and said slowly: "Don't mention it. Facing a lot of technical problems, I am now overwhelmed and irritated."

Li Tianfeng can't help with this project for the time being. Tianfeng Technology now does not have the strength to develop and manufacture drones at all.

Li Tianfeng comforted: "Minister Zhang, take your time and don't worry, these technical problems will be conquered one by one sooner or later."

"Yes." Zhang Haiping could only think of this. Obviously, Zhang Haiping didn't want to talk about this annoying issue. After a change of the topic, Zhang Haiping said: "Mr. Li, your first batch of ten RQ2000 gas turbine engines have been installed in the tank manufacturing plant. Our Type 99 tank will be delivered to the army soon."

The rq2000 gas turbine engine completed a series of factory test runs in June. In early July, the first batch of ten units were delivered. Unexpectedly, the tank manufacturer was so quick that it had installed the engine on the tank.

Li Tianfeng said: "Minister Zhang, we will send an after-sales service team to enter the tank manufacturing plant, enter the army, and provide a series of after-sales services."

Zhang Haiping said: "In the army, you don't need a large number of after-sales service personnel. You can just form a few after-sales service teams and visit the army frequently."

Li Tianfeng agreed happily: "This is OK."

Great Northwest.

This is the base of a certain unit. In the distance, not only were there many military ten helicopters stationed neatly, but also many Type 99 main battle tanks, as well as some armored vehicles, infantry fighting vehicles, etc.

This is Wei Jin's army. Wei Jin was in a good mood these days. Not long after, general Wei Jin was promoted to major general and served as chief of staff of the group army.

In the command room, a colonel smiled and said, "Old Wei, congratulations, you will be our leader in the future, so you must take care of us."

Wei Jin said modestly: "Old Wang, the matter needs to be completely settled."

People feel refreshed when they are happy, and Wei Jin's mental outlook is very good. However, there are more than one happy event. The latest batch of Type 99 tanks have been equipped with troops and are preparing to conduct driving and off-road performance tests.

A training ground.

Several brand new Type 99 tanks were parked neatly, and a small group of soldiers were running over, opening the tank hatch, and everyone entered the tank one by one.

As you all know, this is a new type of tank, but the appearance of the tank looks almost unchanged. Everyone thinks that the tank has not improved much.

After entering, I found a difference. The space inside the tank was obviously larger, and it was no longer as cramped as it was, but was relatively loose.

"I heard that these 99s have been replaced with new engines, but I didn't think about it, and the space inside has also become a little larger."

The rq2000 gas turbine engine is much smaller than the previous water-cooled diesel engine. By the way, after installing such an engine, the internal space of the tank is a little larger, and the tank fuel tank has also been a little larger, but no one can see the changes in the fuel tank.
