Chinese Engine Development

Quickie

China needs a heavy lift chopper. Y-19 maybe in the class of Mi-26. 3 1800kw engine will give them a heavy payload.

Y-19 is the fixed wing transport aircraft. Must be some mistake there because the Y-19 in the picture has jet engines while it's supposed to use turboprop engines.

Guys ... even if the data itself might be real, these images are surely not. Just take a closer look: The image showing the Y-20 is a C-17, the new 3-engined helicopter is a Mi-26 and that strange Y-19 uses an old CG for the Y-20.

As such some daubts about the credebility is surely allowed.

From the latest UCAV Lijian. It seems that it is using a RD-93 engine. But from the engine list develop by China in the China aerospace engine conference. There is no mention of domestic version of RD-93 engine of WS-13. If China is keen on making this UCAV into service. WS-13 shall be a must to be developed in order for PLAAF to accept this UCAV. So the question is has China abandon WS-13 development? But given that they are developing UCAV using this engine, it sound illogical.

Or WS-13 development has already completed?

I find it perplexing that for all the effort in stealth shaping this bird, they leave the engine expose like that. There is ZERO attempt to hide or at least minimized the heat or IR signature of this UCAV.

LO exhausts are very tough science (those who interested can check Ben Rich memoirs about GD/MDC unsuccessful attempt to enlist Skunk Works to design exhaust system for ill-fated A-12 Avenger II, or saga of Northrop/MDC struggle with Lamilloy(TM) exhaust trenches for YF-23)

meantime, X-47A had circular nozzle and somehow lived with that

regarding Sharp Sword, it can be just temporary design decision for prototype vehicle
we just should wait to see operational one

Maybe they are simply testing it with RD-93, and it would be the final engine installed in service, just like how they are testing with the J-20.
