Production? Already? This is massive, massive news. Bigger than the 6th Gen reveals if true.
Footage started appearing last year of the Y-20 test platform flying with a CJ-1000 engine. I'm guessing the engines that have been delivered were only for testing. If so, then I'm not sure "production turbofans" is the correct term to describe those engines.

We have not seen the C909 prototypes equiped with CJ-1000 for flight testings yet. And since it is necessary to test CJ-1000 on C909 before approval for operational use of the new engines, we might see likely 3 or 4 of the existing prototypes be converted to CJ-1000 powered flight testing a few months from today.
If we are lucky we may see the photo of CJ-1000 powered C909 doing taxi run tests in a month or two after delivery, follow by the first test flight later. I am curious how many flight hours are needed to certify air worthiness of CJ-1000 powered C909?

CJ-1000A is in production at least since 2022 for certification process.. certification process of high bypass engine is a very tired process for different type of test and material evaluation so you need many Units of ''XX'' engine.
1. first known airborne test flight of CJ-1000 took place in March, 2023
2. second known airborne test flight of CJ-1000 took place in December, 2024
so this information is extremely valuable but little misleading. they also disclose, team went to the outfield 7 times. MPM means performance test completed too. 1000 hours reliability test successfully passed as well. this piece of information indicate CJ-1000A started its last and final race for complete certificate then will enter in small scale production stage for commercial service.
so a big news ...........
You mean C919, not C909.
How does the CJ1000 compare to the current LEAP-1C that the C919 uses? Slightly worse? Slightly better?
Around the same. The difference is minimal, really. But what I've heard that it's quieter than the LEAP-1C but a tad bit more fuel hungry.
Even a 0.1% increase in fuel requirements is bad when airlines biggest costs is in fuel. Boeing and Airbus are spending billions just to get a 1% fuel efficiency boost. And the LEAP-1C isn't exactly the best engine on the market anyway, with the C919 already lagging behind it's Boeing and Airbus counterparts in range and fuel efficiency even with the LEAP-1C. Hopefully a upgraded variant is in the works.
Yeah I did think about the proper translation. But the original text said 产品, literally "production item". If it was just a sample, it would have been 样品.
