The turbofan 18 engine is the first generation of turbofan engines of Tianfeng Technology Company, with a thrust level of 10,000 pounds and the power of 50 to 70 regional airliners.

Li Tianfeng plans to develop a generation of regional airliner power that is better and better than the turbofan 18 engine on the basis of the second-generation core engine.

On the official website of Tianfeng Technology Company, there has always been a striking countdown sign, at the beginning, Li Tianfeng promised that within three years, the launch of this excellent regional airliner power, and now, with the completion of the design of the second-generation core aircraft to this extent, it is possible to consider the design of the next regional airliner.

This regional airliner is designed on the basis of the second-generation core engine of Tianfeng Technology Company, and compared with the turbofan 18 engine, it will be more fuel-efficient, more economical and more excellent.

From the beginning of June to the end of June, for almost a month, Li Tianfeng paid attention to the design of his second-generation core machine, which was the design of this engine.

In about a month, Li Tianfeng personally drew up this design technical outline, no, at the beginning of July, in the aero engine research and development center, Li Tianfeng convened a meeting.

The people who can participate in this meeting are all the best people in the field of aero engine research and development of Tianfeng Technology Company, the backbone of the backbone, and the elite of the elite.

Tianfeng Technology's aero-engine R&D team, excluding process technicians, has reached a huge number of more than 5,000 technicians, 16 design rooms, as well as supporting test centers, materials engineering centers, electronic research centers and so on.

There are more than 5,000 people, and there are only a few dozen people who can sit here. Completely the elite of the elite. With such a strong R&D team under his hands, coupled with himself as the helmsman and navigator, Li Tianfeng is full of confidence.

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

In the meeting room, it was very quiet. Li Tianfeng is using the projector to explain in detail the design technical outline compiled by himself, even including his own design ideas.

The overall design of the engine is as follows!

The fan is 1st stage, with a diameter of 1.3 meters and a channel ratio of 5.2.

The compressor has six stages, a high-pressure turbine one, and a low-pressure turbine two-stage.

Thrust-to-weight ratio 12, maximum thrust 12000 lbs, fuel consumption ......

Li Tianfeng introduced it in great detail. This engine, using the second-generation core engine technology of Tianfeng Technology Company, can be designed to have a thrust-to-weight ratio of more than 15, but as a civilian turbofan engine with a large channel ratio, the thrust-to-weight ratio of 12 is high enough.

For civilian turbofan engines, the thrust-to-weight ratio is not the most important, the most important thing is low fuel consumption. Low emissions, low emissions. Low maintenance and use cost, high reliability, long life, etc.

Obviously, this engine to be developed fully adheres to this concept, as the design elite of Tianfeng Technology Company. Everyone is well aware of the performance of the turbofan 18 engine, but this engine is much better than the turbofan 18 engine.

After Li Tianfeng's introduction, there was a humane immediately: "Mr. Li, such an engine." Once developed, it will be one of the world's best regional airliner power. ”

Another humanitarian: "Mr. Li, the engine thrust range is 4,700 pounds to 12,000 pounds, which can be used as the power of 30 or 40-seat passenger aircraft or business jets, and can also be used as the power of 50 to 100-seat regional airliners. ”

Sun Xiaoping also said: "Boss, it turns out that you have already planned, the second-generation core machine we are developing now, the design size and power level, are tailored for this engine, and it can be directly moved and used, and basically there is no need to change it." ”

Naturally, at the beginning of the design of the second-generation core aircraft, Li Tianfeng made a long-term plan, and the design size of the second-generation core aircraft was to consider the power of this regional airliner in the future.

It can be moved directly and used with little size change, which will save a lot of trouble and greatly shorten the design and development time of this regional airliner engine.

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

Then, Li Tianfeng said: "The design and development of our regional airliner, although there is a core aircraft, there are also a lot of design and development difficulties, now I will talk to you a little about ......"

Li Tianfeng talked about these difficulties one by one, and even emphasized that when designing, low manufacturing costs, high quality and quality must be considered.

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 in half a year before the end of this year!" ”

"Have faith!"

"No problem!"

Everyone's answer is very loud and powerful, and it seems full of confidence, everyone is so confident, mainly because the design of the second-generation core aircraft has been completed for most of the time, and the design process is relatively smooth, in addition, more importantly, there is Li Tianfeng, the pilot.

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.

After the review, Li Tianfeng seems that the design technical outline has been very perfect and very reasonable, and the design can be carried out on this basis.

A few days later, the design of the engine began, based on the second-generation core machine.

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

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

The turbofan 21 engine, although it is only a civilian regional airliner engine, is very advanced and excellent, and it still arouses the interest of many people, such as Zhang Haiping.

Zhang Haiping read the design technical outline, and happily called: "Mr. Li, the turbofan 21 engine is very advanced, it will definitely be very good, such an engine, once it is put into the market, I think many people should be depressed." ”

Li Tianfeng laughed, "Minister Zhang, it's still early, no, it's just the beginning of the engine design work." ”

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

Li Tianfeng nodded, but agreed with this, this time next year, it 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, I didn't think that you paid so much attention to our turbofan 21 engine, how about your drone project?" ”

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 anxious and irritable." ”

For this project, Li Tianfeng can't help much for the time being, and the current Tianfeng Technology does not have the R&D and manufacturing strength of drones at all.

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

"Hmm." Zhang Haiping could only think so, obviously, Zhang Haiping didn't want to talk about this annoying problem, and after a change of words, Zhang Haiping said: "Mr. Li, your first batch of ten RQ2000 gas turbine engines have been installed in the tank factory with our Type 99 tanks, and they will soon be delivered to the troops." ”

RQ2000 gas turbine engine, a series of factory tests were completed in June, and the first batch of ten units was delivered in early July.

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

Zhang Haiping said: "In terms of troops, you don't need a large number of after-sales service personnel, you can set up several after-sales service teams and visit the troops frequently." ”

Li Tianfeng happily agreed: "That's okay." ”

……….

Great Northwest.

This is the station of a certain army, and in the distance, not only a lot of Wuzhi 10 helicopters are neatly parked, but also a lot of Type 99 main battle tanks, as well as some various armored vehicles, infantry fighting vehicles, and so on.

This is Wei Jin's troops, Wei Jin is in a good mood these days, and soon 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 said with a smile: "Old Wei, congratulations, you will be our leader in the future, but you have to take care of us." ”

Wei Jin said modestly: "Lao Wang, the matter has to be completely settled." ”

People are in good spirits on happy occasions, and Wei Jin's mental outlook is very good, but the happy events are not limited to this one, the latest batch of Type 99 tanks have been equipped with troops, and are preparing to carry out driving and off-road performance tests.

A training ground.

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

Everyone knows that this is a new type of tank, but the appearance of the tank looks almost unchanged, and everyone thinks that the tank has not improved much.

After entering, I noticed that the space inside the tank was obviously a little larger, no longer so cramped, but more relaxed.

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

RQ2000 gas turbine engine, than the previous water-cooled diesel engine is not smaller, by the way, after installing such an engine, the internal space of the tank is a little larger, and the tank fuel tank is also a little larger, but the change of the fuel tank can not be seen.

Today's two watches, the second one is sent! (To be continued......)
