Y-20 has max payload of 60 tonnes. Shave off one engine and it should still be able to do 40 tonnes easy. You don’t need 40 tonnes of additional fuel to power a single 350 kN engine for tests. 3 WS-18 are not going to struggle with carrying a single CJ-2000 in engine out conditions so long as you’re not flying max payload on the Y-20 testbed.
by the time, D-30/WS-18 have been replaced with WS-20 engines even on testbed aircraft.
Probably not necessary. No point redoing integration tests with new engines for a testbed plane.
Well, if we take the Il-76 as an indication (which is after all a related design that is very close in size and configuration):
Fan diameter 2.9m, weight 6.4t (the test engine was pretty grossly overweight). Both are equivalent to a GENx-class conventional turbofan. If anything, the 35tf thrust load could be the biggest problem.
fine. so you are saying Y-20 should be able to carry CJ-2000 easily. above latenlazy sir cleared.
Last eek we saw the first image of the new engine testbed based on the Y-20A, but as it seems (if this image is a recent one) the good old Il-76SK (?) is still active. But does anyone have an idea what engine this is, it looks wider than the original D-30KPs but not like a WS-20?
Might’ve been the WS-15 lol.
WS-15 is way past that stage. It was already tested on a J-20 last year.
You are right in that it could be a low-bypass fighter engine in a casing.
I'd say a WS-19 or WS-21.
