Shangguan Yuqiang handed Wang Bu'an a business card.

Puzzled, he took it. I found out that the name on it was actually my own.

The following title is powerful - Chief Technical Consultant of the Ministry of Aerospace Industry of China (department level).

"What is this?"

"Newest part-time job. ”

"How many part-time jobs do I have now?"

"Not much. ”

"How much?"

"Eighty-seven. ”

"Not much, surely.

"Not much, really. ”

Wang Buan pouted quietly.

Yes, not much. Less than a hundred. There is no such thing as the former Heshen.

The question is......

There is also a parenthesis at the end.

Auditorium-level ......

This one is a bit of a.

What is the concept of the department level? That's a big official.

Wang Buan's own Laozi was only at the official level before he resigned. There are also deputy department level, department level, and deputy department level...... Then it's the turn of the main hall level!

How old is he now? Just with a parenthesis at the hall level? Isn't that envious, jealous and hateful?

I don't know who came up with the idea? It's all about hatred!

If it is made public, it will definitely arouse the excitement of netizens across the country.

At that time, it is estimated that the whole world is speculating about which high-ranking official surnamed Wang is his Wang Buan's Laozi.

If one is not good, maybe someone will throw eggs at him and end up like Bao Longxing. Maybe even worse.

Also, this position doesn't seem quite right!

There are also many part-time jobs below.

One of them is the technical consultant for the commercial large aircraft project.

Why is the matter of COMAC related to himself again?

At the beginning, it was said that Tyrannosaurus Rex Industries was only responsible for providing engines. Not responsible for any other items.

With the technical strength of COMAC, there is no need for Wang Bu'an to further intervene!

Just get the engine right and you're good to go.

The 270 engine is for commercial aviation.

Large transport aircraft, large bombers, large commercial aircraft...... All of them are used. It is perfectly compatible.

Generally speaking, there is a big difference between commercial engines and military engines.

Commercial engines place special emphasis on reliability, stability, and economy. Emphasis on the longest possible lifespan.

In a word, it is to save energy and save money.

Otherwise, the airline will lose money.

Military engines, on the other hand, mainly emphasize explosive power, maximum thrust, and so on. For economy and longevity, it can be put into second place for the time being.

Lao Maozi's military engine is the most typical example. Previously, longevity and economy were almost not considered. Blindly pursuing performance.

The MiG-25, MiG-31, are the best representatives of this idea.

For the sake of performance, everything else can be ignored.

"Who gave this to me?" asked Wang Buan.

"It's Minister Pei of the Ministry of Aerospace Industry. Shangguan Yuqiang replied in a low voice.

"Oh. Wang Buan nodded.

Well, it's a big deal.

Ministry of Aerospace Industry.

Supervised the production of all aircraft.

Whether it's commercial or civil. All fall under its jurisdiction.

What is Chengfei, Shenfei, Xifei, Nanfei, Hafei, Guifei, and Commercial Flight...... And so on, all of which are subordinate industries.

"Commander, what do I want to catch first?" Wang Bu'an was confused.

"The top priority now is to ask you to help deal with the domestic large aircraft project. Cheng Laifeng said.

"Isn't there already a C919 project team?"

"Do you think we'll meet regional jets with just over 100 seats?"

"Okay!"

Wang Buan nodded.

Of course not!

The domestic large aircraft is the most important industrial symbol of a country.

In today's world, there are only two largest manufacturers of passenger aircraft. One is Boeing. One is Airbus. They carved up the entire market.

The vast majority of passenger aircraft in the world are either Boeing or Airbus series.

The others are all petty and cannot be put on the table.

Including the polar bear's own Il.

Huaxia buys a large number of commercial airliners from foreign countries every year.

In some cases, an order can be tens of billions of dollars. In a year, it could exceed $100 billion.

Obviously, this is a big expense.

Now, we're going to earn the money ourselves.

This matter has nothing to do with Cheng Laifeng.

However, the Ministry of Aerospace Industry arranged it, and Wang Buan was temporarily under their control.

According to the previous agreement, after Wang Buan returned to China, the first thing to deal with was the two project teams. One is the C929 project team. One is the C939 project team.

"C929, the project of a medium-sized commercial airliner. Two hundred to three hundred. ”

"C939, large commercial airliner project. Three hundred to four hundred. ”

"In addition, there is a C969 project group that has not yet been launched. It mainly focuses on super-large passenger aircraft with more than 600 seats. ”

Shangguan Yuqiang handed Wang Bu'an detailed information.

These two projects are directly related to White Feather Whale Technology.

The main research and development is the responsibility of COMAC.

But in the end, it was the white feather whale technology.

Or, more precisely, Wang Buan's signature is required. Otherwise, it cannot be passed.

Frankly, this regulation is very overbearing. It's very unfair to COMAC. Why should others sweat and exert their strength, and in the end they have to leave it to others to decide their own fate?

Wang Buan seems to have felt the hatred from all the employees of COMAC.

He accepted such a task every time.

A professional backstabber, it's definitely not a lie.

"Let's take a look at the modification of the C919 first. Wang Buan said slowly.

"Okay. That's all there is to it. Shangguan Yuqiang took out a large pile of documents.

Wang Buan began to study the materials.

Now that you've taken over, you have to make a difference.

In terms of comprehensive performance, it is impossible to surpass Airbus and Boeing for the time being.

Wang Buan has always been very self-aware. Don't dare to speak outrageously.

Wear as big a hat as big as your head.

Eat as much as you have a big mouth.

After all, someone else has eaten more salt than he has ever eaten rice.

It is unrealistic to want to surpass Britain and catch up with the United States in a very short period of time.

However, it is still possible to make something unique in terms of engines and seize the market segment.

According to the data, the weakest point of the C919 domestic large aircraft is still the engine. We don't have a domestic engine to work with. Must be imported.

(Well, the independent intellectual property rights of domestic large aircraft advertised to the outside world...... Don't care about these details...... ）

The twin-engine turbofan medium-sized CFM-LEAP-X1C engine equipped with the C919 is a large jet airliner engine developed by CFM International, a joint venture between General Electric of the United States and SNECMA (Safran) of France. The engine is a modification of the previous generation of aircraft, with better fuel economy and lower CO2 emissions.

At present, China has become the main market of CFM International. More than 3,000 CFM engines are in service or on reserve for the entire China market.

In fact, in addition to the imported CFM engine, there are two domestic engines as a replacement.

One is the Yangtze River 1000 and the other is the Yangtze River 2000, but there is no data.

"The other party has always refused to provide it. Shangguan Yuqiang said.

"Don't rush. Wang Buan reminded.

"Why?"

"We've offended people now. ”

"Why?"

"We have robbed others of the fruits of their labor!"

"Oh. ”

Shangguan Yuqiang actually didn't understand.

What does it mean to rob others of the fruits of their labor?

Wang Bu'an obviously didn't do anything! These things were all stuffed to him by others.

To be honest, Shangguan Yuqiang is still very sympathetic to Wang Buan. It's just the hardest worker bee. I just got off the plane, and I was still at the airport, so I had to start getting busy.

That's right, Wang Buan is still at the airport. Didn't leave at all. It is estimated that he will have to live here for a while in the future.

Cheng Kailong specially chose a building here as Wang Buan's office.

This is a military restricted area, and the security is relatively guaranteed.

Throughout the airshow, Wang Buan will live here.

If there are any technical problems in the middle of the air show, the first thing is to ask Wang Buan to solve them.

In order for Wang Buan to concentrate on his work, everyone else was asked to leave.

Including Huang Ruoxi, Pei Lan, and Zhou Xiaoqi, they were all arranged to live in other places.

Now the C919 is ready to install two 125 engines.

Two 125 engines, which can provide about 120 tons of thrust.

For a commercial aircraft, this thrust is already very good.

Its maximum take-off weight is around 73 tons.

The maximum landing weight is about 67 tons.

The thrust of two 125 engines is enough for it to soar into the blue sky.

The C919 large aircraft, in the passenger aircraft team, can only be said to belong to the regional airliner. The range is about 5500 km.

It is aimed at Airbus A320 or Boeing 737 regional airliners.

The 125 is actually a military-type engine.

Installed on commercial airliners, it's not impossible. The same is compatible.

However, from a professional point of view, it is better to develop a new model of engine.

According to the first draft of the design, after the new engine is used, the model of the C919 will become the C929. This is where the C929 project comes in.

After the new engine, the layout of the C929 is very different from that of the C919.

There is no need for fuel tanks. There is no need for bulky engines.

There is no need to think about the range.

There is no need to think about fuel costs.

There is no need to cut the weight harshly.

Its body can be made more spacious and more seats can be added.

Previously, the standard number of seats was between 158 and 168 seats. But now, it can be completely increased to about 185-195 seats. The seats have also become more spacious. There's more storage space too. There are more and more mechanical and electrical equipment that can be installed, as well as various service facilities. You can even consider installing a massage seat. Anyway, I don't care about the weight or anything.

In general, it is the original slender streamlined type, which has become thick and fat, and the appearance has indeed declined.

Economically, however, it has been turned upside down.

The standard C919 flies at Mach 0.78-0.8.

The C929 with a modified 125 engine can fly at a speed of more than Mach 1.2.

In times of danger, its extreme temperature can even exceed Mach 1.5, which is almost twice the standard speed of the original C919.

In other words, it will become a supersonic commercial airliner. It will fly at supersonic speeds.

That's why Wang Bu'an was arrested to be in charge of this project.

Supersonic commercial airliners! Be cautious!
