April 8th.

A bombshell-level message suddenly spread wildly on the Internet.

C919, the first domestic civil large passenger aircraft, announced that it had broken the ban on the sale of foreign advanced engines and successfully achieved mass production!

The news exploded on the Internet.

Many netizens don't believe it's true.

"How is this possible? How long has it been since the ban was imposed? ”

"It should be the engine I bought, this is indeed the fastest way to solve the problem."

"No, it's not! As mentioned in the press release, the domestic CJ-1000 large bypass ratio engine is not inferior to the LeapX engine produced by CFM International in terms of thrust, fuel consumption, service life and other aspects. ”

"Impossible!"

Immediately someone shook his head: "Absolutely impossible, we are more than 30 years behind foreign countries in the field of engines, and it is absolutely impossible to catch up in just a few months, there is a problem, there is definitely a problem with this news." ”

"But COMAC did solve the engine supply problem, and rolled off the assembly line in batches of 10 mass-produced C919 passenger aircraft at one time, and it can be seen from the details in the picture that the engine mounted under the wing is obviously different from the LeapX engine or Maozi's PS90 engine, which seems to be slightly smaller, and it should be a domestic engine."

"Even if it's a domestic engine! Nor is the performance likely to be on par with LeapX, at least more than a generation behind! In order not to breach the contract, the outdated engine had to be used, and in the actual use process, the fuel consumption alone was not competitive...... Users will definitely return the goods one after another, just dying! ”

"Shepherd Dogs, get out! No matter how bad the domestic engine is, it is also our engine, and the fuel consumption is larger! It doesn't matter if the ticket price is high, I'll buy it! ”

"Yes, we must support domestic large aircraft, and the air ticket is more expensive than it can afford!"

Netizens said that even if the ticket price is relatively expensive, they will make domestic aircraft.

For the support of netizens, COMAC was very moved, and immediately sent a letter of thanks, and also said at the back of the letter of thanks: The engine problem has been completely solved, the performance is indeed not worse than the LeapX engine, and the fuel consumption index is even lower.

Wow......

This reply made some netizens overjoyed and extremely excited.

But more netizens still don't believe it.

"Bragging!"

"Impossible!"

"Lie! Deceitful! ”

There are still a small number of netizens who still firmly believe that this is a scam.

……

April 9, morning.

Shanghai International Airport.

At the end of one of the runways, there is a production C919 aircraft that is mostly painted in the red color of the national flag.

This morning, the C919 will make its first passenger flight, which will be loaded with 168 passengers and headed for another airport 2,800 kilometers away.

Without refueling and returning home, two take-offs and landings, plus the round-trip distance, a total of 5,600 kilometers.

At this moment, thousands of people standing on both sides of the airport runway, in addition to the majority of media reporters, the most are the workers, leaders and relatives of COMAC.

Chen Jin and his mother He Li were also in the crowd of farewells.

"Lao Chen, do you really want to get on the plane and personally participate in the passenger test?"

He Li asked, her face was a little worried, and she even grabbed her husband Chen Gang's hand, shaking her head slightly, a little unwilling for him to go.

"It's okay, I'm confident enough in the plane we made ourselves!"

Chen Gang gave his wife a firm look, and he was 300 percent sure of this passenger test flight.

"Dad, has the engine on our plane really reached a particularly powerful level? I remember that the maximum range of the C919 at the beginning was 5500 kilometers, and you have to fly 5600 this time and take off with two large fuel consumption. ”

Chen Jin couldn't help but ask.

He felt that today's passenger test was a bit risky, in case the alternate fuel was insufficient, or ...... Phew, he slapped his mouth.

"No problem, absolutely no problem!"

Chen Gang explained: "Compared with the most advanced LeapX engine, the thrust of our engine is about 5% smaller, but the fuel consumption is 10% smaller, reaching an astonishing 0.432kg/, and because our aircraft is 15% lighter, the actual thrust-to-weight ratio is not small, and the thrust is completely sufficient." ”

"The most amazing thing is its range performance, you may not believe it, in the virtual factory simulation environment, the C919 full of guests, flew out of the limit range of 8000 kilometers, almost 50% more than the initial design range, although the fuel consumption in the take-off stage is a little higher, but do two take-offs and landings, fly 6000 kilometers in the middle, there is no problem at all."

"But we only flew 5600, leaving more than 400 margins."

"In addition, we also want to tell the majority of netizens who care about domestic large passenger aircraft, our customers, and CFM International, which bans the sale of engines, that our engines are OK! Our planes are absolutely brilliant! ”

Speaking of this, Chen Gang was a little excited, and he had the urge to vent freely.

Chen Jin nodded, the margin of more than 400 was a bit risky, but it was completely sufficient.

"Dad, go on! Go and visit the great mountains and rivers of the motherland, today is the day when your dreams come true. ”

Chen Jin gave two thumbs up and watched him board the C919.

9:50 a.m.

The tower gave the command that it could take off.

"Start the engine ......"

"Start sliding, accelerate ......"

"Pull up the lever and lift the nose wheels off the ground ......"

"Increase the thrust and take off successfully!"

At 13:01 p.m., the plane successfully landed at another airfield 2,800 kilometers away.

After an hour's stay at the airport and a meal, all passengers boarded the plane again with the crew.

At 14:05 in the afternoon, the plane taxied and took off again, and rushed into the sky with greater acceleration.

17:00 p.m.

More than 100,000 on-site spectators and millions of surrounding spectators at Shanghai International Airport and its surroundings are looking forward to the western sky.

Countless people were excited, clenched fists, or tears in their eyes, like countless radars, at the same time facing the west.

This passenger test is a 360 live broadcast without dead ends, and under the eyes of tens of millions of pairs, there is no room and possibility for cheating.

If the domestic engine works, then that plane will come back.

If the domestic engine does not work, then the plane ......

Actions speak louder than words!

Actions speak louder than keyboards!

And at this moment, everyone is anxiously watching.

Everyone prayed in their hearts: come back, you must come back, no matter whether the domestic engine works or not, the plane must come back!

There are more than 160 lives on it!

Suddenly!

A low "buzz~" sound sounded.

"Look over there, everybody!"

Someone exclaimed, pointing in one direction.

Everyone looked in that direction, and then suddenly exclaimed and stirred.

"It's back!"

"Our plane is back!"

I saw it in the orange sun that was setting, against the backdrop of the red glow in the sky.

A red-painted airplane, like a fiery red streamer, drilled out of the sun; The roar of the bigger and bigger engine, like the cry of the phoenix, symbolizes the rise and rebirth of an ancient nation!

Buzz~

Witnessed by countless pairs of eyes.

As the plane landed steadily on the runway.

"Boom~"

"It worked!"

"Wow!!"

"Woo woo woo~"

Cheers, shouts, cries......

The entire international airport was a sensation, the entire business sea was a sensation, and the entire land of China was in a boil!
