The efficiency of Tianfeng Technology Company is still very fast, with the substantial increase in production capacity, the production and manufacturing speed of each part is relatively fast, and the assembly of the fourth and fifth prototypes of the turbofan 16 engine has also been put on the agenda.

In less than 20 days after the first flight of the Y-8K aircraft, the assembly of components for the prototype of the turbofan 16 engine for the C919 large airliner had begun.

The first step in the assembly of aero engine is the assembly of each component, and the basic assembly of each component is completed, and then these parts are assembled together, and finally assembled into a qualified aero engine.

The comprehensive trial production and process verification of the parts of the "TFWS002" turbofan are also in full swing, and the comprehensive trial production of this engine part has been carried out for several months.

Some important key parts, some parts with relatively complex processes, their process verification has been carried out several rounds, each round, then the manufacturing process of the parts is perfected, several rounds of trial production of parts, the manufacturing process is more and more perfect, more and more mature, according to the process specifications of the parts manufactured, the quality is more and more stable, more and more excellent.

Li Tianfeng is coming back from the production site, at this moment, Li Tianfeng knows in his heart, it is estimated that by next month, the first "TFWS002" turbofan will also begin to enter the final assembly, and then start a series of test runs.

Because the core engine of the "TFWS002" turbofan is the same as the core engine of the turbofan 16 engine, many parts do not need to be tested and verified, which saves a lot of things, otherwise, where is there such a rapid progress.

As for the "TFWS003" turbofan, it is designed on the basis of the turbofan 16 engine. It also saves a lot of work, and the design work is nearing completion.

After the completion of the design of this engine, the trial production and verification of parts will also begin, and Li Tianfeng is also full of confidence in this engine.

The market prospect of a 10,000-pound large-channel ratio turbofan engine with a thrust grade is also relatively broad. No, the full design has not yet begun, and at the Zhuhai Air Show, Embraer made it clear that it was ready to order this engine.

Perhaps, many people will think that it is impossible, the engine has not been successfully developed, it is only the design stage, how can there be an order, how can someone order this engine.

This is within the aviation industry. It is a common thing, GE, Rolls-Royce, Pratt & Whitney and other aero engine giants will not mention, even in China, it is also a common thing, and it is particularly obvious in the aircraft manufacturing industry.

For example, our ARJ21 regional airliner has already had a lot of orders in the development stage, such as the C919 airliner, and now the first prototype has not yet begun to fly test. There are already orders for more than 300 aircraft.

It's far away, let's get down to business.

Li Tianfeng is more concerned about his "TFWS003" turbofan engine. The design information sent by Sun Xiaoping, Li Tianfeng took a closer look at it when he had time, and checked it.

Because there is a ready-made "template" there, that is, the turbofan 16 engine, Li Tianfeng did not give Sun Xiaoping too much guidance on the design of such an engine as the "TFWS003" type. only grasped the general direction, and I have to say that the design team led by Sun Xiaoping is extremely good.

The design of this engine, because it is close to the end of the comprehensive design, Li Tianfeng often looks at the design data. Overall, the design is very good.

It fully adheres to the low noise, low emission, low fuel consumption, high safety and reliability, extremely high maintainability and so on.

The 3D design color map of the engine has long come out, this engine looks a little similar to the turbofan 16 engine, like a smaller version of the turbofan 16 engine, but the channel ratio is a little larger, so that the fuel consumption is lower and more economical.

………

Time flies so fast, and with some busyness and hard work, my two turbofan 16 engines have completed the test run smoothly, and the factory test table is excellent.

In the office.

Li Tianfeng was looking happy, and was talking on the phone with Ma Delong of COMAC, Li Tianfeng said: "Mr. Ma, I have good news for you." ”

Ma Delong said: "Mr. Li, have our two turbofan 16s completed the final assembly?" From Maderon's tone, it was clear that expectation was felt.

Li Tianfeng smiled and said: "Mr. Ma, you are really like a god, our two turbofan 16 engines have not only completed the final assembly, but also completed the factory test run smoothly, and have reached the deliverable state." ”

Ma Delong's heart was light, and he said in surprise: "Mr. Li, that's great, this is the best news I've heard in the past few days." ”

Li Tianfeng said: "Mr. Ma, then we will transport these two engines over and load them on our C919 passenger plane." ”

Li Tianfeng knows that the C919 passenger plane is basically close to completion, and he is only waiting for his turbofan 16 engine, and as soon as these two engines arrive at COMAC, they will definitely install this almost completed C919 passenger plane as soon as possible.

However, Ma Delong's sexual urgency was completely beyond Li Tianfeng's expectations, obviously he had waited for so long, and he had already stopped waiting at all.

Ma Delong said: "Mr. Li, this time we have to transport the engine by air, and the engine will be loaded directly onto the plane from Huangping Airport, and our C919 passenger plane has been waiting for too long." ”

It's been too long!

This is the entire Chinese nation for almost half a century of waiting, foreign developed countries, in the sixties and seventies of the last century, launched the big aircraft project, the current Airbus, Boeing those large planes are even more thunderous.

As a big country and an economic power, China cannot always be without a large aircraft, and the Yun-10 aircraft with great hopes died halfway, and the current C919 large passenger aircraft will take on a heavy responsibility.

We also have a big plane, and it's a great big plane!

Li Tianfeng can fully understand Ma Delong's mood, and even, Li Tianfeng still admires them a little in his heart, the team led by Ma Delong, from the establishment of the C919 aircraft, research and development, all the way, to today, will finally have results.

Li Tianfeng knew that they had paid a lot for the C919 passenger plane, and now they were anxious to have their own two engines, and their mood was completely understandable, so Li Tianfeng said: "Mr. Ma, our two turbofan 16 engines will be shipped out immediately, loaded on today's plane, and arrive at your company today." ”

Ma Delong said happily: "Okay, Mr. Li, thank you so much this time, you promised to be a month, but it was eight days ahead of schedule, and the final assembly of these two engines was completed eight days in advance, and the factory test was completed along with lì, you are amazing!" ”

Recalling these two engines, Li Tianfeng couldn't help but think of the scene of his employees working overtime, many parts of these two engines were rushed out by his employees working overtime, otherwise, where would it be so fast.

According to the normal schedule, the production and manufacturing cycle of many parts takes more than a month, but under the situation of overtime and 24 hours a day, it only took more than 20 days from the beginning of the original commitment to COMAC to the official delivery, which is eight days ahead of schedule.

Li Tianfeng thought in his heart, this may be a little contribution he has made to China's large aircraft project!

On the phone, Li Tianfeng and Ma Delong negotiated a qiē matter, and the two turbofan 16 engines were immediately shipped out of Tianfeng Technology Company, directly to Huangping Airport, installed at the airport, and transported to COMAC.

………

Today's COMAC, the final assembly manufacturing center, is brightly lit and busy.

The two turbofan 16 engines arrived at COMAC along the way, and the assembly of the engines began immediately, as well as some finishing touches.

In the huge assembly and manufacturing center building, the huge C919 passenger plane is parked there, and the workers are busy, and the two turbofan 16 engines are being loaded into the engine compartment, which is tense and orderly.

Ma Delong, Shen Wensheng and other senior executives of commercial aviation companies are there, watching the assembly of the aircraft, and a strong sense of accomplishment can be seen from everyone's eyes.

Shen Wensheng said: "Mr. Ma, Tianfeng Technology Company is really fast, these two turbofan 16 engines came over so quickly." ”

Ma Delong nodded and said: "Tianfeng Technology Company is good, it will be our most important partner in the future, whether it is our ARJ21 or our C919 passenger aircraft, my plan is to install all the turbofan engines produced by Tianfeng Technology Company." ”

An executive next to him looked humanitarian: "Mr. Ma, our plane is no longer equipped with imported engines?" ”

Ma Delong waved his hand and said: "I think the turbofan engine of Tianfeng Technology Company is very good, we will gradually reduce the share of imported engines, and gradually install all our domestic turbofan engines." ”

This is the first time that Ma Delong has expressed his position in front of everyone, and before, he may have had such thoughts in his heart, but he has never said it as one of his own executives.

Shen Wensheng said: "Our domestic aircraft is to be equipped with a domestic engine, I heard that the turbofan 16 engine is installed on the Yun-8K transport aircraft, and a series of test flights have been completed, and the table is very good, and the military is very satisfied." ”

Everyone chatted about Tianfeng Technology Company, chatting about the turbofan 16 engine, the two turbofan 16 engines gradually completed the assembly, and the workers were smoothly loaded on the C919 passenger plane, and now, the engine is in place, and the whole C919 passenger plane has looked decent.

Ma Delong said: "Mr. Shen, arrange it immediately, our senior management team will have a family photo, and the background is this C919 passenger plane." ”

Soon, a group of executives of COMAC stood in front of the plane, and with a "click", a family photo was taken, and behind everyone was the C919 passenger plane.

Today's two shifts, the second shift is complete. (To be continued......)
