This should be the maximum thrust on the test bench; For longevity and endurance, the rated power won't be that high.
Chinese Engine Development
- Thread starter jackbh
- Start date
Probably something like an AN-225 then, which has been discussed here before but I don't know if we've ever heard anything about China ever working on such an aircraft. I don't think it even needs it. A Y-40(?)/C-5 class transport is more than sufficient for China
CJ-1000/CJ-2000 developed by ACAE. which is strictly for commercial use and CJ-2000 specifically designed for C929 with required 35 tons thrust.
Shenyang is developing 25 tons class high bypass turbofan. there is also tender of WS-35 Engine being released this year.
AN-124/C-5 equivalent Chinese aircraft most likely use this WS-XX engine or WS-35.
Trent 7000 is rated at ~330kN maximum, CJ-2000 will probably be slightly derated if not kept at that thrust to accommodate a heavier aircraft than the A330. There is no way the current CJ-2000 will be derated all the way down to 250kN.
NK-93 is rated at only 180kN which is only ~50 percent of the thrust of CJ-2000 and is about half the weight of a Trent 7000 (3,650 kg vs 6,445 kg). Limiting factor would be how much thrust and weight the pylon and wing can handle not the size of the engine.
yeah it depends on the wing's strength. but don't you think it would be expensive for AECC to buy 747 then modify for only Engine testing. i know it will be useful for future programs as well.
but it will be interesting to see which option they go with.
Even with 10-20% reduction, the engine thrust would still be somewhere from 28.2 ton-force to 31.7 ton-force, which is still quite excessive for an An-124/C-5-class airlifters.
Unless they're going for Il-100-sized airlifters, that is. But that would be a massive jump indeed.
China does not need such massive airlifters, especially if such airlifters are meant for use by the PLAAF. China doesn't have a lot of runways that are rated for An-225 operations, of which the number is only going to be scarce during wartime.
Also, do remember that the An-225 was conceived by the USSR primarily for ferrying the Buran space shuttle and rockets for the Buran Program, and NOT for transporting troops and military equipment.

a downgrade variant of CJ-2000 in 25-28 tons category class Engine just like Russia did with PD-35. they derived PD-26 from this engine for strategic airlifter.
but China doesn't need to do that, they have flexibility and enough resource for separate program. this is why WS-35 introduced. this is the most likely military version of 25-35 tons category machine.

I won't be worried about that. Both AECC and SOE airlines are state owned, "buying" between them is not really a buying but a internal asset repurposing like account tick-off and tick-on.
