J-35 carrier fighter (PLAN) thread

i still don't get it why this guy keep bragging about RD-93 engine.

even WS-13 latest variant has better thrust , inlet temperate , T/W ratio than RD-93. let alone WS-19

stop exaggerating Russian tech in 2022.

I think him talking about rd-93 has no problem in and by itself. It’s the best estimation we currently have of the engines available for the J-xy currently. No it’s not the WS-13 variant that’s most likely on the J-xy, but it most likely have some common areas like core design, rough range of thrust, TSFC, etc, because at the end of the day the WS-13 can indeed trace it’s lineage back to the rd-33 family. However his exact arguments also bewilders me somewhat.

Nobody here would have the accurate performance data of military engines and aircrafts, so all the discussions here are based on simplified and inaccurate model. I don't think anyone would have the privilege to underrate the opinions of the other and declare a victory.

WS-19 is, or should be, definitely better than RD-93, but it would not be a fairy tale.

For the 4th gen. fighters, most payload were hung under their wings or main frame. But for the 5th gen. stealth fighter aircraft, the request to load all the fuel and weapons within internal tanks and weapon bays would request them to be bigger, with larger volume/size ratio.

Also, since all the Chinese military avion enterprises share most of the achievements of engine technologies, if WS-19 could be supposed to have such huge progress from RD-93, then why can't we suppose that the new batch of the WS-15 engines were also greatly increased in their performances?

FC-31 or 35 would be a legend only when you overestimate the performance of WS-19 but underestimate that of the WS-15.

WS-15 was always be estimated 15t thrust and 1.6t weight, with a T/W ratio of a bit less than 10.

But the most exaggerated estimation for WS-19 is 12t thrust and a same 1.06t weight as RD-93, a legendary TWR of 11.5!

Obviously, only in this way can the fc-31 surpass the j-20 in performance. But how could that be possible?

WS-15 is probably going to be 17-18t thrust. There’s nothing magical about the WS-19 having a T:W ratio of 11.5. EJ200 stage two engines are supposed to have a T:W ratio of 12. That’s what this class of engines are naturally capable of so long as the materials are advanced enough.

it is not you. my massage was for someone else.

but J-35 or whatever you name this aircraft Fly with WS-21 engines. it is the new name of WS-13 advance variant. WS-13 base variant can indeed trace it’s lineage back to the rd-33 family but newer variant has nothing to do with RD-93. chamber redesign and incorporated next generation components and materials.

he absolutely know nothing about WS-15.

initial design of WS-15 was for 16.5 tons. but breakthrough in advance materials and processing techniques in 2010's decade made possible to redesign WS-15 engine. now dry thrust stands at 24,500 lbs.

I know man, that post is just my personal view on the matter. Cheers!

EJ2x0

Stage 1:

The EJ2x0 with 20% growth compared to the original EJ200. The EJ2x0 engine will have dry thrust increasing to some 72 kN (or 16,200 lbf) with a reheated output of around 103 kN (or 23,100 lbf).[15]

Stage 2:

The new engine plan to increase the output 30% more power compared to the original EJ200. The engine will have dry thrust of around 78 kN (or 17,500 lbf) with a reheated output of around 120 kN (or 27,000 lbf).[15]

The wiki hasn’t been updated for years lol. Either way if that target thrust wasn’t unachievable it wouldn’t be announced.

Would you please provide some news source proving that the 12t thrust stage 2 enhancement of EJ200 is in volume production now?
