I am not here to spoon feed u.Go search yourself from open sources,,it cleared trials on il-76 but its heavy and lacks optimum wet thrust.
Plus we cannot mass produce the single crystal blades yet,,,u think we won't do it in next 10 years??
It will be done,don't worry
Let's assume what you are saying is true, which is debatable, but let's say it is true.
What fighter would use this engine. Rafale? Nope. Tejas? Nope. PAKFA? Nope. MKI? Nope. You have no other planes, AMCA? That's too far into the future and it's medium fighter, so even if it were true Kavari can't power it. I have also heard of a joint venture with Russia on a transport, but that one uses Russian engines, not Kavari.
There are no fighters that would use this engine, there is no incentive to finish this engine, and even if finished, who would use it.
As to IL-76, that's really not a good indication, all it shows is that somehow it won't fit into a fighter. Which I have never heard happen before.
I seen the specs for Kavari engine, it is like WS-13, in terms of performance, though the WS-13 can actually power fighters now, WS-13 is the weakest of the Chinese engine family.
So, no, the difference is defiantly not 10 years.
If you still like to debate, cool, but ask yourself, even if it was done today, what fighter would it even power.
