Damn she's powerful. 35.2 tons is no joke.
Chinese Engine Development
- Thread starter jackbh
- Start date
This test basically completed in March, 2025. but AECC just disclose this information.
Zhuhai air show 2021, AECC released a promotional video of CJ-2000 Engine. in which they gave the hint of commercial certification date.
but program development speed exceed their own expectations. basically Engine is completed they can start flight testing as soon as next year or maybe early.
1. it has full composite casing plus full sized large composite wings.
2. 4th/5th generation powder alloy high pressure turbine disc tailgate.
3. integrated manufacturing of large size drum shafts and powder trays.
4. CMC high pressure turbine blades.
5. heavy used of composite and 3D printed parts.
there are many ''First'' Technologies applied on this Engine. basically never used before on any Chinese Engine.
It's not, COMAC signed for RR engines already, it's probably going to a option directly from launch though.
COMAC didn't sign anything with RR but they intend to use Trent7000 for initial C929 flight. let see what happens in coming years.
Isn't it too powerful for that? I believe the WS-20 is around 14-15 tons, this is more than twice of that for a single engine.
I don't think they'll use a Y-20, similar engines like the Trent XWB and GEnx were both tested on much larger aircraft such as B744 and A380 testbeds. It's probable AECC might convert a retired B744 from one of the state-owned airlines into a flying testbed for future engine development.
More likely to appear in C-5-class super-heavy transport aircraft
Indeed a more likely option.
Well, but before you use it on a new aircraft esp. in that class it has to be tested in flight somewhere first!
Without any derated variant, CJ2000 at 35.2 ton-force of thrust is too powerful for super-heavy airlifters of the C-5/An-124 category.
