During the morning's mobilization meeting.
They faced the bright national flag.
The tenacity and fighting spirit of the tens of thousands of Shang Fei's employees were all ignited.
Everyone held their breath and swore to mass-produce a large domestic passenger plane!
However, after the surging passion cooled down, the reality in front of them was still cruel.
The so-called collective oath and shouting a few slogans were only to stabilize the morale of the staff and unify their thinking.
However, there were always more solutions than difficulties.
In the process of calling the second elder, the CEO of Shang Fei, He Jin Long, took out his alternative solution.
"Buy the PS90 engine manufactured by the Russian aircraft parts manufacturing group.
"This engine model of the Russians is quite good. It has low fuel consumption, reaching the level of the CFM56-5C. It has a service life of more than 10,000 hours and a longer time between major repairs. The purchase price is also one-third cheaper.
"The long-range wide-body passenger plane C929 that we jointly developed with the Russian company UAC is expected to use the PS90 series engine.
However, although the Russian PS90 series engine was good, the price was much cheaper.
However, the fuel consumption was still 16% higher than the Leapx engine.
The service life was reduced by about half.
As for the failure rate, the Russian engine always gave people a feeling that it was not particularly reliable.
Purchasing the Russian PS90 engine was the only way to alleviate the problem before the domestic replacement engine was successfully developed … However, it would still greatly reduce the market competitiveness of the C919.
From this, it could be seen that the civil aviation engine field was somewhat similar to the chip industry. It was winner-take-all.
It was difficult for the losers to even get the soup.
He Jin Long still tried his best to guarantee, "We will seize the time and continue to optimize our plane! Although the engine's fuel consumption is a little high, the body of our C919 passenger plane is generally about 15% lighter than similar planes from Boeing and Airbus. If we cut some redundant weight, we can achieve a weight lighter than them by 18%.
"The lighter the plane, the faster the speed, the lower the fuel consumption.
"In addition, our production cost is about 20% lower, which is a very affordable price. After the launch, we will still have a certain degree of market competitiveness."
The reason why the C919 was lighter and much cheaper was that the people of Z had mastered an amazing technology.
The 3D printing technology for large structural parts.
This technology had not achieved major breakthroughs in foreign countries. They could not print large structural parts with a diameter of a few meters or more than ten meters.
However, the 3D printer in Z country could.
Using this technology, the 3D printer could print key components such as the main beam of the aircraft wing, the fuselage frame, and so on. The strength was up to standard, and the material utilization rate was more than 90%.
As for Boeing and Airbus, they still used traditional industrial machine tools to process the wing main beams and other components. The scrap rate was high, the material utilization rate was low, and the production cost and production efficiency were at a great disadvantage.
Due to the support of 3D printing technology, Shang Fei Corporation's C919 had a huge competitive advantage in the market. It could even be said that in the market for 200-seater passenger aircraft with a 5,000-kilometer flight range, it immediately became the king of price-performance ratio.
It would sweep the market for commercial airliners.
The Boeing Company and even the European Airbus Company had motives to obstruct them … Before they mastered the 3D printing technology, they didn't want a competitor like the C919 to appear in the market.
After the C919 used the Russian-made PS90 engine, the advantages brought by the 3D printing technology were immediately offset, and it immediately became a mediocre aircraft.
Moreover, given the Russians' character, even if their products' performance wasn't that great, they wouldn't hesitate to raise the price. Buying their engines now was cheap, but that might not be the case in the future.
"We still have to have our own advanced engine. We have to fight for it!"
The number two elder on the phone said with a sigh.
He Jin Long fell silent.
…
At this time.
The secretary walked into the office. "President He, the deputy chief designer of the landing gear project team, Chen Gang, wants to see you. He said that he has an important matter to report to you."
Chen Gang?
Chen Gang, who was missing from the mobilization meeting in the morning.
When someone snitched on him, a trace of displeasure flashed across He Jin Long's face.
But he still didn't take it to heart. Who asked him to have such an amazing son?
But the mobilization meeting was such a serious event. At the critical moment when they needed to unify their thinking and fighting spirit, he was actually not there? What did this mean?
He Jin Long was still a little disgusted.
He didn't really want to see this person.
But he heard the secretary say again, "President He, Designer Chen also brought his son here. He's the founder of Xing Hai Technologies.
"Yes, yes, yes. Ask them to come to my office."
…
They entered the office.
"President Chen, welcome, welcome. You're young and promising, really young and promising."
He Jin Long extended his hand with great enthusiasm.
"Old Chen, you've given birth to an amazing son." He shook Chen Gang's hand and patted him on the shoulder.
But He Jin Long felt strange. Why did this father and son want to see him? Why did they come to see him?
Could it be that they were disheartened by the hopelessness of mass production of the domestically produced large passenger aircraft and wanted his approval to retire early?
He Jin Long cursed in his heart. He gestured for them to sit down and asked the secretary to pour two cups of tea.
After chatting for a while, he asked, "May I know why the two of you are here?"
"Of course it's for the engine. We have things to do …" Chen Gang said impatiently.
"Uh-huh ~"
Chen Jin coughed twice. "The main reason is to discuss the development of the domestically produced engine with you, President He. This topic is more confidential and high-end. My dear secretary, could you please go out and close the door?"
He looked at the male secretary.
"Xiao Lin, go out for a while and close the door." He Jin Long immediately understood and let the secretary out of the office.
There were only three people left in the room.
Chen Gang said impatiently, "President He, my son's company has a way to solve the problem of the domestically produced engine's performance!"
"Dad, why are you in such a hurry?"
Chen Jin looked at him helplessly. "Sit aside and don't talk. Let me talk to President He first."
He Jin Long looked at him in surprise. His face was full of suspicion.
Chen Gang shut his mouth in embarrassment.
"President He, I'd like to take up some of your time to talk about the development of the domestically produced engine. Would you be willing to talk to me?"
"Sure, sure. Of course."
He Jin Long nodded.
The two of them began to talk.
Usually, it was Chen Jin who asked the questions and He Jin Long who answered.
"President He, tell me the truth. How many years do you think the difference is between our country's engine and the most advanced foreign engine?"
"Uh, at least 30 years. To be honest, it could even be 50 years."
"Why is it so different?"
"The engine is the product that best reflects the industrial foundation of a country. Our foundation is still too weak. The West has been industrializing for more than 300 years. We have less than 60 years. The gap in many basic areas is too big. The simplest example is that the Mericans landed on the moon 52 years ago. We still can't do it.
But I've read in many articles that we have conquered most of the material technology that makes up the advanced engine. Materials are no longer a problem. The main problem is the engine design. We are not as good as others. Is that the reason? "
"Yes, you're right!"
He Jin Long nodded. "We have made up for the material shortcomings. The main problem is the design. Our country has not produced a top-notch engine designer."
Of course, the engine's poor performance was not entirely the fault of the designers. The lack of investment from the country was also a big part of the reason.
Because a good engine was not only designed, but it was also built by burning money!
Professional wind tunnels, test stations, and other equipment were not to be mentioned.
Every time they did an engine test, they would consume a few tons of aviation fuel. Moreover, they had to burn it every day, every year.
For example, if they threw a rock the size of a fist into the engine, the engine that was worth tens of millions would be completely destroyed.
Not to mention when the economy of Z country was in dire straits, it was still not enough even when Z country was rich and powerful now.
To put it simply, an advanced aviation engine had to be "paid for" day after day, year after year, to have a chance of winning.
Once the engine was dismounted midway, all the previous efforts would be wasted.
Only an expert in paying for gold could become an engine manufacturing powerhouse.
But …
Chen Jin had a plug-in in his hands. Not only could it save him a lot of money, but it could also greatly shorten the engine development cycle.
Chen Jin described to He Jin Long the plug-in that "saved thousands of tons of fuel per day," "arranged for hundreds of engines to be tested at the same time," and "shortened the development cycle by 90%."
