I Found A Planet

After drinking about half a catty of liquor.

Chen Gang lay down on the table, and immediately became drunk and passed out.

He fell asleep until 10:00 am the next day, when a hand pushed him awake, and a voice rang in his ear.

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

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

I have to go to work today, and I slept until ten o'clock!

Put on the coat and pants, and went directly to the office 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 will swear an oath in front of the national flag, unify their thinking, overcome difficulties, and vow to solve the problem in the shortest time... He must also go to the scene.

I didn't expect to oversleep after drinking a few cups.

"Dad, don't go."

Chen Jin grabbed him, "Tell me the specific situation."

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

"My company can't make engines, but there is a way to help make them. Is this useful?"

Chen Gang paused.

He looked at Chen Jin seriously and said, "Engine is the crown of industry. There are only five countries in the world capable of producing aero-engines. The strongest engine companies all have hundreds of years of technology accumulation. Xinghai Technology was established. several years?"

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

"Dad, let me ask you, which one do you think is more difficult, making an engine or making a chip?" Chen Jin asked suddenly.

"Uh... almost, it's hard."

"Zhongxin International has conquered the 7nm process within eight months. Do you know this? Xinghai Technology's technology is used."

Chen Gang's eyes widened.

He was finally in no hurry to rush to the company, and the two sat on the sofa in the living room and chatted in detail.

Chen Jin was most interested in the question: Why did the French break the commercial contract that had already been signed?

The cost of each C919 is about 30 million knives, and the two engines account for 30% of the manufacturing cost... The engine is not only the most valuable, but also the most profitable.

However, for orders of at least a few thousand engines and billions of dollars in profits, the French say no to it.

"Actually, the French don't want to tear up the contract. Such a large order is enough for Safran Group to survive ten years. There is no company that does not want to enter a market of 1.4 billion people."

"Under pressure from the people of country M, the French were forced to rescind the contract."

"Because CFM International, a subsidiary of the Safran Group responsible for the production of the LeapX engine, has shares in General Electric (GE) of M country, and the core engine technology used in the LeapX engine comes from the technology authorization of M country...the sale of engines is prohibited for COMAC. Regarding this matter, Safran Group has no right to speak."

Country M has the final say on everything.

"That means that General Electric can also make money from selling engines, and the people of country M can also make money...Why is the sale still banned?" Chen Jin asked strangely.

"It should be that Boeing sent people to lobby the Congress of country M, and obstructed it, messing up the contract."

Chen Gang said: "Our C919 is cheap, fuel-efficient, and environmentally friendly. Once it is introduced to the market, it will erode Boeing's market share and damage their interests. Of course, they will use all means to suppress it."

However, what Boeing did was relatively subtle. After all, the country Z market is the largest sales market for Boeing aircraft. Once they offend country Z and are sanctioned by country Z, it is estimated that the country Z market will never be with them.

Therefore, those who promote the ban on the sale of engines to COMAC are the few politicians in the Congress of country M who are the most enthusiastic about it.

Apparently they also achieved their purpose.

The mass production plan of C919 was interrupted in an instant.

"With such an obvious weakness of the engine, isn't there any plan in advance to deal with the worst case? Key equipment, will foreign countries get stuck in our necks?"

"Once they run out of stock, we won't be able to replace the domestically-made engine in time, so we can do nothing?"

Chen Jin frowned and said, core technology and core equipment cannot be bought. Even if someone sells some core equipment to you in order to earn your money, they can disregard the spirit of the contract and sell out of stock at any time, and the lifeline will always rest with others hand.

You have to have something of your own.

"We have domestically produced large bypass ratio engines!"

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

"One is to introduce from abroad, and strive to realize the mass production of C919 in the most convenient way and at the fastest speed... The domestic large passenger aircraft project has been in progress for 15 years, but the development cycle of the engine is as long as 20 years, three years. Ten years, if we want to put C919 on the market quickly, we can only take the road of introduction, we can’t wait for 20 or 30 years, and neither can the users who bought C919.”

"In addition, we established a commercial engine manufacturing company (Shangfa) to be responsible for the research and development of the supporting engine for C919. The engine model is Changjiang-1000. At present, the C version of the engine has been produced, and the thrust, service life, and reliability have been greatly improved. improvement."

"But it's not enough! The CJ-1000C engine is at least 20 years behind the LeapX engine, and its service life, reliability, and fuel consumption are far inferior to the latter. Even if the scientific researchers of Shangfa Company work hard, it will take about ten years. , in order to come up with reliable alternative products.”

ten years?

Chen Jin shook his head, the waiting day lily was cold.

Thinking of one thing, he asked: "Shangfa's engine is not good, can the military engine work? I heard that the domestic large military transport aircraft Y-20 has already used the domestic turbofan-20 engine, and it is being mass-produced. Our C919 is equipped with military Won't the WS-20 also be able to immediately get rid of foreign dependence?"

Why not use a military engine?

"No way!"

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

"In terms of service life, civilian engines can generally reach more than 20,000 to 30,000 hours, with thousands of hours between overhauls, low failure rates, 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 do not fly every day, and the frequency of use is much lower. There are no strict requirements on engine life. A few thousand hours is enough. The military's maintenance support is also better, and the reliability of the engine is almost the same. It doesn't matter."

"There is also economy. For airlines, the biggest operating expense is fuel. In their eyes, an airplane that saves 15% of fuel is completely different from an airplane that is not fuel-efficient. Buying an airplane that saves 15% of fuel is equivalent to With 15% more profit, they will not hesitate to buy fuel-efficient aircraft.”

"Fuel saving is mainly achieved through the engine. The better the engine, the more fuel efficient it is, and the stronger the market competitiveness."

"But our CJ-1000 or the military turbofan-20 consume more than 30% more fuel than LeapX, which is doomed to have no market competitiveness. No airline is willing to buy it. Profit is the life of these companies."

In summary.

The C919, a large domestic airliner, must be equipped with an engine that has a long service life, high reliability, and economical fuel efficiency, in order to be competitive in the market, otherwise users will not buy it.

Most of the orders that have accumulated to nearly 5,000 will be lost due to exceeding the delivery date.

So... helpless.

Both helpless and angry.

Chen Jin shook his head again and again. He never thought that it would be 20X1 years, and the technical level of domestic engines and the situation they faced would still be so bad and severe.

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

His greatest wish is to travel around the great rivers and mountains of the motherland on the domestically-made large passenger plane he participated in the development of before retiring at the age of 60.

After thinking for a while, he said, "Dad, don't worry, I can help with this matter. The domestic aircraft engine problem will be resolved for you within half a year!"

Chen Gang looked at him suspiciously.

Chen Jin spent about an hour describing a certain technology.

Father Chen Gang's eyes widened suddenly, with ecstasy on his face.
