Tianfeng Technology Company.

Two turbofan 16 engines will be produced and will be used for the test flight of the 919 passenger aircraft and started on the same day of production. However, the parts produced can be produced not only in the amount of two engines, but in the number of parts of ten turbofan 16 engines at one time.

This once again shows Li Tianfeng's courage and confidence.

Generally speaking, a new aircraft engine has a prototype of six to eight. Before these prototypes complete a series of tests and verifications, small batches of parts are generally not produced and manufactured.

The reason is very simple, that is, a series of problems may arise and expose during the test and verification process of the prototype. In response to these exposed problems, the engine may be changed in the design or even major design changes.

When the design changes, the size or structure of some parts will be changed. Parts produced and manufactured according to the original design drawings cannot be used and can only be scrapped.

If small-scale production is put into use before this, many parts may be scrapped, causing relatively large losses.

However, Li Tianfeng is very confident that the possibility of major design changes for the turbofan 16 engine is very low. Even if the design changes or improvements are required, it will be a small change and the losses to the parts are not large.

After receiving the production task of producing ten turbofan 16 engines, Sun Kangke was far less calm and confident than Li Tianfeng, so he ran to Li Tianfeng's office.

Sun Kang said worriedly: "Tianfeng, investing in the production and manufacturing of ten engines at one time is a little too risky, if..."

Li Tianfeng smiled confidently and said, "Brother-in-law, do you remember the development of our turboshaft D engine? At the beginning, we also invested in the production and manufacturing of ten engines at one time. Otherwise, the development progress of the turboshaft D engine was not so fast."

Sun Kang thought about it and nodded, "Tianfeng, how confident are you in the turbofan 16 engine? After all, this is a large bypass turbofan engine with extremely high technical content."

Li Tianfeng said: "It's okay. As I said, we will arrange the production and manufacturing of ten turbofan engines. We will start to enter small batch production and manufacturing, and wait for the turbofan 16 engine to complete the field test flight test and obtain a production license. We will consider increasing the production and manufacturing batch again!"

Also increase production and manufacturing batches!

Sun Kang looked at Li Tianfeng with admiration. Sun Kang also felt a strong sense of confidence from Li Tianfeng's expression. So Sun Kang said: "Tianfeng, then we will start small-scale production and manufacturing."

Li Tianfeng nodded and reminded: "Brother-in-law, we will hand over the two turbofan 16 engines to COMAC, and the progress requirements are the fastest."

Sun Kang said: "I have already thought about this aspect. I have checked our inventory. I have checked the parts inventory of the turbofan 16 engines, and give priority to the production and manufacturing of the missing parts of these two turbofan 16 engines."

Because the production and manufacturing levels of parts are different, the passing rate and scrap rate are also different. Some parts are invested in a large amount, some parts are invested in a relatively small amount, some parts are process verification and test multiple times, and some parts may be completed in one or two batches.

Therefore, the parts in stock feel a little uneven, some have more parts, enough to produce several turbofan 16 engines, and some have fewer parts. Even the last time the two turbofan 16 engines were manufactured, they lacked three parts.

Seeing Sun Kang say this, Li Tianfeng nodded. He thought to himself that his brother-in-law was really considerate and could check the parts inventory clearly.

Li Tianfeng and Sun Kang talked about the production and manufacturing of these two turbofan 16 engines in the office. They also talked about the production and manufacturing of ten turbofan 16 engines that are about to be put into production.

COMAC, assembly and manufacturing center.

A 919 passenger plane has basically been completed, but the engine is installed on the wings, which is a temporary shortage of the turbofan 16 engine.

The 919 is the second domestic large passenger aircraft independently designed and developed by China after the 10th anniversary of the movement.

The meaning of the first "9" is forever, and the "19" represents that China's first large passenger aircraft has a maximum passenger capacity of 190 seats.

It is the initial letter of Hina and the initial letter of COMAC's English abbreviation a. It may also mean that it is determined to enter the international large passenger aircraft market and to form a coherent pattern in the international wide-body large passenger aircraft manufacturing industry with Airbus (Airbus) and Boeing (Boeing).

As early as June 2011, COMAC's 919 large passenger aircraft debuted at the 49th Paris Air Show. In November 2012, it was unveiled at the Zhuhai Aerospace Exhibition, and received 15 Chinese and foreign users. So far, the order quantity has reached more than 300.

The 919 passenger aircraft was originally planning to use the Leap-1 engine provided by M International, but with the emergence of Tianfeng Technology's turbofan 16 engine, if nothing unexpected happens, the power of the 919 passenger aircraft will use the turbofan 16 engine with better performance.

Today, Madron once again came to the assembly and manufacturing center and looked at the aircraft with satisfaction. This is the first prototype of the 919 aircraft. It not only successfully completed the structural assembly stage, but also completed the avionics system, control system, and internal decoration.

Looking at this large plane, Madron suddenly remembered a sentence, everything is ready, only the east wind is needed!

As a vice president of COMAC, Shen Wensheng was with Ma Delong. When Shen Wensheng saw this prototype, he said happily: "Mr. Ma, it seems that it won't take long for our 919 aircraft to fly into the blue sky."

Ma Delong said: "This is a large aircraft project that gathers national strength. It must fly into the blue sky. This is the will of the country and the will of the people!"

Shen Wensheng said: "Our large passenger aircraft adopts advanced aerodynamic layout and new generation supercritical wings and other advanced aerodynamic design technologies to achieve better cruising aerodynamic efficiency than the current similar aircraft, and has comparable cruising aerodynamic efficiency with the competitive aircraft in the market in ten years. I am very confident in the first flight."

Ma Delong said: "Our 919 passenger aircraft has excellent power. The turbofan 16 engine has excellent comprehensive performance, ultra-low fuel consumption, noise and emissions. Mr. Shen, our large passenger aircraft has such excellent power, you will make a great contribution!"

Upon hearing this, Shen Wensheng felt happy. In the final analysis, if we pursued the reason, the key was Shen Wensheng's contribution. If Shen Wensheng had not led the team to Tianfeng Technology Company in person, maybe things would have been another situation.

The 919 passenger plane is still waiting for the turbofan 16 engine, and the improved Y-8, that Y-8k transporter, has completed the assembly of the engine.

These two turbofan 16 engines have been successfully installed on this Y-8K transport aircraft. Many technicians and inspectors are conducting final inspections and commissioning.

A few days later...

Under the traction of a tractor, the Yunbak slowly left the huge aircraft assembly factory and headed towards the airport. The Yunbak will conduct a test flight in two days.

This is an airport belonging to a test flight in a certain flight test institute. Many test flights of aircraft are carried out here. After being pulled to the airport, the Yunbak was parked in a designated location.

Many people at the airport, including maintenance, ground crew, test pilots, etc., are very familiar with Yunba. It happened that many people saw this Yunba k being pulled over.

"Wow, what kind of plane is that??"

"Yunba doesn't know him either. Lao Zhang, you are not confused, right?"

"I'm confused, Lao Yuan, take a closer look. Is this Yunba?"

Upon hearing this, Lao Yuan, who was preparing to conduct a routine inspection of a fighter plane, looked away. At first glance, he really thought it was Yunba, but when he looked closely, he soon discovered many differences.

Two turbofan engines!

The body also seems to be wider and larger!

"Old Zhang, this is really not Yunba. Yunba is not like this. Is this a new type of transport aircraft we have developed?"

"It's said it's a newly developed transport aircraft, but it doesn't look like it at all. It's said it's Yunba, but it doesn't seem to be." Lao Zhang looked at the distance in confusion.

It happened that a test pilot passed by the two people and couldn't help but smile when he heard the words of them, "You don't know this plane. This is a new type of Y-BaK, which has been improved and upgraded based on the Y-BaK aircraft."

"No wonder, it turned out to be the Y-8k, but before that Y-8 had four turboprop engines, and this time it was changed to two turbofan engines. This engine looks good and imported from that country."

The test pilot smiled and said, "What imported one? This is a real domestic engine, a turbofan 16 engine. Have you heard of it?"

"Ah! This is the turbofan 16 engine. I have only heard of it before and have never seen it. It turns out that it is an engine like this and looks very good."

Like Lao Zhang and Lao Yuan, there were many people who were pulled over to see this Yunbak. When they saw this plane, people who knew a little suddenly became furious and talked with relish. There were many people pricking their ears around them.

Yunbak stopped steadily, and the tractor slowly left. Seeing this, many people trotted over and surrounded this Yunbak, and watched with relish.

"It looks much better than the previous Yunba."

"Yes, at least it looks much more beautiful. The two turbofan 16 engines are really powerful!"

"I heard that this plane will fly for the first time in two days."

"Ah! It's going to be a first flight!"

When I heard that the first flight was about to take place, many people were in a hurry to get on, and I thought to myself, the first flight is really looking forward to it!

…………

Two updates today, and the second update will be given.

In addition, let me explain that in reality, the first flight of the real 919 passenger plane is not that fast. Don’t link it with reality. For the plot of this book, the 919 passenger plane will also be the first flight in the near future. (To be continued.)
Chapter completed!
