After drinking about half a catty of liquor.

Chen Gang leaned on the table and was immediately drunk and unconscious.

After sleeping until 10 a.m. the next morning, a hand woke him up, and a voice rang in his ears.

"Dad, don't sleep, get up."

Chen Gang slowly opened his eyes, picked up his mobile phone and looked at the time, and immediately lifted the blanket and sat up from the bed.

I still have to go to work today, and I actually slept until more than ten o'clock!

Put on a coat, put on pants, and go straight to the company without going to the bathroom to wash your face and brush your teeth!

The company is going to hold a mobilization meeting today, and all employees swear in front of the national flag, unify their thinking, overcome difficulties, and vow to solve problems in the shortest possible time...... He had to go to the scene as well.

I didn't expect to oversleep after a few drinks.

"Dad, don't leave yet."

Chen Jin grabbed him, "You tell me about the specific situation." ”

Chen Gang shook his hand, still walked forward, and shook his head: "What's the use of telling you, your company doesn't make engines?" ”

"My company can't build engines, but there is a way to help build the engine, is this useful?"

Chen Gang paused.

He looked at Chen Jindao with a serious face: "The engine is the crown of industry, only five countries in the world have the ability to build aero engines, and the strongest engine companies all have hundreds of years of technology accumulation, and Xinghai Technology has only been established for a few years?" ”

Chen Gang shook his head: "Your company can't help." ”

"Dad, let me ask you, do you think it's more difficult to build engines and chips?" Chen Jin suddenly asked.

"Uh...... Almost, it's hard. ”

"Zhongxin International conquered the 7nm process in eight months, do you know this? What is used is the technology of Xinghai Technology. ”

Chen Gang's eyes widened.

He finally stopped rushing to the company, and the two sat on the sofa in the living room and chatted in detail.

The question that Chen Jin is most interested in is: why did the French break the commercial contract that had already been signed?

Each C919 costs about $30 million, and the two engines account for 30% of the manufacturing cost...... Engines are not only the most valuable, but also the most profitable.

However, at least an order for a few thousand engines, billions of dollars in profits, the French say they don't want it.

"In fact, the French don't want to tear up the contract, such a big list is enough for the Safrant Group to survive ten years, a big market of 1.4 billion people, and there is no company that does not want to come in."

"It was under pressure from the people of Country M that the French were forced to tear up the contract."

"Because CFM International, a subsidiary of the Safran Group, which is responsible for the production of LeapX engines, has a stake in General Electric (GE) in country M, a large number of core engine technologies of the LeapX engine originate from the technology licensing of country M...... Saifeng Group has no say in the ban on the sale of engines by Commercial Airlines. ”

Everything is up to country M.

That shows that General Electric can also make money from selling engines, and people in M can also make money...... Why is it still banned? Chen Jin said strangely.

"It should be that Boeing sent someone to lobby the Congress of Country M, which made an obstacle and messed up the contract."

Chen Gang said: "Our C919 is cheap, fuel-efficient, and environmentally friendly, and once it is introduced to the market, it will erode the market share of Boeing aircraft and damage their interests, and they will of course suppress it by any means." ”

However, Boeing is more obscure in this matter, after all, the market of country Z is the largest sales market for Boeing aircraft, once it offends country Z and is sanctioned by country Z, the market of country Z is estimated to be out of contact with them.

Therefore, the people who pushed for the ban on the sale of engines to COMAC were the happiest in the face of the announcement, and it was a few politicians in the Congress of Country M.

Apparently they also achieved their goal.

As a result, the mass production plan of the C919 was interrupted in an instant.

"With such an obvious weakness in the engine, is there no foresight for the worst-case scenario? Key equipment, foreign countries will not stuck our necks? ”

"As soon as they are out of stock, we will not have a domestic engine to top it in time, so we can only be at a loss?"

Chen Jin frowned and said, the core technology and core equipment can't be bought, even if people sell some core equipment to you in order to make your money, you can ignore the spirit of the contract and run out of stock at any time, and the root of your life will always be in the hands of others.

You have to have your own stuff.

"We have a large domestic bypass than the engine!"

Chen Gang said: "When the large aircraft project was established, we took into account the problem of stuck necks and adopted a two-way walking strategy. ”

"One is to introduce C919 from abroad, and strive to achieve mass production of C919 in the most convenient way and at the fastest speed...... The domestic large passenger aircraft project has been done for 15 years, but the engine development cycle is as long as 20 or 30 years, if you want to make C919 put into the market as soon as possible, you can only take the road of introduction, we can't wait for twenty or thirty years, and users who have purchased C919 can't wait. ”

"In addition, we set up a commercial engine manufacturing company (Shangfa) to be responsible for the research and development of the C919 supporting engine, the engine model is Changjiang-1000, and now we have come up with the C version of the engine, which has greatly improved thrust, service life and reliability."

"But it's not enough! The CJ-1000C engine, at least more than 20 years behind the LeapX engine, has a service life, reliability, and fuel consumption that is far inferior to the latter. ”

Decade?

Chen Jin shook his head, and the daylily that didn't wait was cold.

Thinking of one thing, he asked: "If the engine of Shangfa is not good, is the military engine good?" I heard that the domestic large military transport aircraft Y-20 has already used the domestic turbofan-20 engine and is being mass-produced, and our C919 military turbofan-20 engine can not immediately get rid of foreign dependence? ”

Why not use military engines?

"No way!"

Chen Gang still shook his head: "The requirements for the use of civilian engines are far more stringent than those of military engines. ”

"In terms of service life, civil engines can generally reach more than 20,000 or 30,000 hours, with an overhaul interval of thousands of hours, low failure rate and low maintenance costs...... After all, each aircraft is related to the lives of hundreds of people, and it must be absolutely reliable. ”

"Military engines do not have this requirement, military transport aircraft will not take off every day, the frequency of use is much lower, there are no strict requirements for engine life, generally a few thousand hours is enough, the military's maintenance support is also better, and it doesn't matter if the engine reliability is almost."

"There is also economy, for airlines, the biggest operating expense is fuel, fuel saving 15% of the aircraft and not fuel-saving aircraft, in their eyes is completely different, buy a fuel-saving 15% aircraft, they will have 15% more profits, they will not hesitate to buy fuel-efficient aircraft."

"And fuel saving is mainly achieved through the engine, the better the engine, the more fuel-efficient, the stronger the market competitiveness."

"But our CJ-1000 or military turbofan-30 has more than 30% greater fuel consumption than LeapX, which is destined to have no market competitiveness, no airline is willing to buy, and profit is the life of these companies."

Sum up.

The domestic large passenger aircraft C919 must be equipped with a long-service life, high reliability, economical and fuel-efficient engine in order to be competitive in the market, otherwise users will not buy it.

Orders that have accumulated to nearly 5,000 aircraft can only be lost because they exceed the delivery deadline.

So...... Helpless.

Both helpless and angry.

Chen Jin shook his head again and again, he didn't expect that it had been 20X1 years, and the technical level of domestic engines and the situation they faced were still so bad and severe.

Looking at his father's angry and frustrated expression, and seeing the white hair growing on his temples, Chen Jin suddenly realized: Dad is 53 years old this year.

His greatest wish is that before he retires at the age of 60, he will take a large domestic passenger plane that he participated in the development of and cruise the great rivers and mountains of the motherland.

After thinking about it, he said: "Dad, don't worry, I can help with this matter, and the problem of domestic aircraft engines will be solved for you within half a year!" ”

Chen Gang looked at him with a suspicious expression.

Chen Jin spent about an hour describing a certain technique.

Father Chen Gang's eyes suddenly widened again, and his face showed ecstasy.
