What are they suppose to say, that WS-10 is a piece of junk? In Zhuhai airshow, they said the thrust level of WS-10 at the moment is 12.5 kg. Do you forget so fast?

They had 371 posts thread on CD, because the most well known big shrimp on Chinese military bbs said Taihang is still not as good. They need more work and time.

But clearly, you know more than him, a guy that was part of the Su-30MKK project. Read that thread, look at how well he is respected on this matter.

And it's not just him. None of us here are hoping for WS-10 will fail and J-10 or J-10B project slows down. But if AL-31FN is the more reliable engine right now, then J-10 and J-10B has to go with that.

If WS-10A is not mature and not enough thrust, it will not be used on new prototype for initial flight test of J-15S, J-16 and J-20. WS-10 is doing very well and PLAAF trust it. There is no reason not to put it on J-10B as demonstrated by a prototype of J-10b running WS-10A.


And if that's not enough, answer these questions.

Why would Shenyang Liming give up valuable orders? CAC is clearly going ahead with J-10A production and using Russian engines. Why would Shenyang Liming not sell CAC when it has production to do so?

This is even more absurd. I don't think we need a genius to figure out selling an engine is more profitable or selling a whole plane(j-11b) is more profitable? Worst of all you are selling the engine to an rival....

If Shenyang does not use FWS-10 for its new aircraft, what engine is it going to use? The Russians are not stupid, they are making sure all of their new AL-31F are going to the old aircraft. Why do you think so many J-11B aircraft were sitting outside SAC with no engines just 2 years ago? How many AL-31F engines do you think SAC has in storage that it can even use for new aircraft or prototypes?

That is just your assumption. J-11b uses Ws-10 engine is always PLAAF target and priority. You are now linking it to russia not going to supply AL-31F for PLAAF if they uses it on J-11b? How about the initial batch of J-11b and J-15 using AL-31F? How come Russia still continue to supply further more AL-31F engines to China? How can Russia ensure AL-31F goes to old plane only?

And we have seen at least one J-10B flying with FWS-10A. If it's not flying it for the purpose of hoping that the engine will be ready and for all the flight tests to succeed. What's the reason?

As I say early, SAC dirty move of trying to limit Chengdu J-10b cannot be expressed openly or say openly. ("We gonna limit J-10B, make PLAAF buy only J-11b!!"). You think SAC is some idiot? They need to act along and play accordingly to please PLAAF. Letting them test one prototype tested with J-10B will not killed them but letting serial production of operational J-10B will be a big problem.

Xi'an AE is Shenyang Liming's biggest competitor. Yet, WS-15 and WS-20 designed by SAERI gets produced by Xi'an AE. That's a case where part of Shenyang aircraft corporation is helping out a competitor rather than giving the project to another of its subsidiary. How does that work? Isn't SAC so powerful that it can override the desires of PLA on all except the biggest matters?

As I say J-20 is a high priority program just like PL-12 and KJ-2000. Nobody or even SAC dare to screw up this project. WS-15 is for J-20. So what do you think? And I already mention before, engine is not the core lifeline for SAC, Making a plane is. Chengdu is stepping on SAC toe. Xi'an is not...

You seem to forget the difference between the Al-31F and FN which also explains the reason why WS-10s for J-11s are different when compared to those for J-10s.
The original Al-31F has its gearox on top of the engine to fit the Flanker. However, the J-10 resembles Western aircraft in its engine bay design. As such, the gearbox of Al-31FN had to be moved below the engine to enable the turbofan to be fitted in the J-10. Because of this the WS-10s fitted in J-11s are also unsuitable for J-10s.

Of course i am aware of this. But do you think when Chinese design WS-10 engine will make it so complicated and logistic hard between engines for J-10b and J-11b that will delay J-10b production? Differences of course there is, but not until a extend will causes massive maintenace or logistic difficulties for Chinese to handle between J-11b and J-10b. Clearly this is not the problem to delay J-10b.

the best that russia can produce right now (117S) has 14500 kg of thrust, acording to wiki. Thats a significant gap. Of course we have to understand that ws-10 is the first chinese turbofan, while russia has been producing turbofans for decades.

Xi'an AE is Shenyang Liming's biggest competitor. Yet, WS-15 and WS-20 designed by SAERI gets produced by Xi'an AE.

why did XAC get the production role for WS-15? because of liming´s performance regarding the production of WS-10? but ws-10 problems are mainly design or production?

My dear Lion, you are in self denial.

We shall wait and see. As more time drag by and J-10B nowhere in sight to enter service. That will prove my theory correct.
PLAF will not be happy to see J-10b enter service in AL-31FN, cos its lower thrust of engine could not provide super cruise for it. With SAC not providing engine, delay is the only option unless Chengdu goes for 117S which provide far superior thrust.

Well, I said we could have a truce on this and you want to continue.


so according to you, FWS-10A allow J-10B to super cruise? lol. good one, you clearly know more about Chinese aviation on J-10 project than Pupu.

You are the most knowledgeable Chinese aviation expert there is. All hail the great lion.

Yes, there is nothing wrong with what China is going thorugh with FWS-10. It has experienced a lot of pain since it's the first major turbofan engine it has developed. Of course, Shenyang Liming's production issues haven't helped.

Xi'an AE got production role for WS-15 and WS-20 I think. They also produce 1/3 of the parts for each Taihang engine. Their company is publicly traded, so you can read up stuff on their projects that you can't with any of the other Chinese engine producers. They have produced WS-9 for a while now and we haven't heard about any of the problems that we've heard about with Taihang.

Clearly, you know more than Pupu, oh Great lion.

Clearly, single engine aircraft is the same as double engine aircraft.

Clearly, China has so many extra AL-31F around that it can use at anytime.

Clearly, J-10B didn't have enough test flights with AL-31FN before flying with FWS-10A.

Clearly, Chinese flankers are like J-10s, they are not constrained in production if there is no Taihang for them.


This is even more absurd. I don't think we need a genius to figure out selling an engine is more profitable or selling a whole plane(j-11b) is more profitable? Worst of all you are selling the engine to an rival....
Has CAC stopped producing J-10? What does Liming have to gain by not selling engine to CAC? Does it look like this evil strategy by Shenyang Liming is reaping any reward so far? I've written about this. Each engine is at least $4 million and two engines is $8 million. You have all the added lifetime support and spares that you get on top of that. How much do you think each J-11B cost? $35 million? How much of that is produced by SAC? If you take out the engine cost and radar cost and sensor cost? What do you have left? $20 million or less? The after sale servicing you get back with engine is a lot more than just on the aircraft itself. You have to take it back every 500 flight hours for overhaul. After a couple of times, you have to get new engines. How much more profit do you think Shenyang Liming is giving up here?

That is just your assumption. J-11b uses Ws-10 engine is always PLAAF target and priority. You are now linking it to russia not going to supply AL-31F for PLAAF if they uses it on J-11b? How about the initial batch of J-11b and J-15 using AL-31F? How come Russia still continue to supply further more AL-31F engines to China? How can Russia ensure AL-31F goes to old plane only?
you obviously don't follow the Chinese forum on this issue. The initial production batch of J-11B was clearly using AL-31F, so PLAAF was fine with producing J-11B if FWS-10 engine was not available. If SAC had that many spare AL-31F lying around, why do you think J-11B production basically stopped for 2 years with those aircraft parked outside the company airfields. Don't you think PLAAF wanted those aircraft?

As I say early, SAC dirty move of trying to limit Chengdu J-10b cannot be expressed openly or say openly. ("We gonna limit J-10B, make PLAAF buy only J-11b!!"). You think SAC is some idiot? They need to act along and play accordingly to please PLAAF. Letting them test one prototype tested with J-10B will not killed them but letting serial production of operational J-10B will be a big problem.
oh great lion, you know more than all of us here. You know about SAC and CAC relationship better than everyone else. You know about Liming and 601 and 112's relationships better than anyone here. Teach us more.

As I say J-20 is a high priority program just like PL-12 and KJ-2000. Nobody or even SAC dare to screw up this project. WS-15 is for J-20. So what do you think? And I already mention before, engine is not the core lifeline for SAC, Making a plane is. Chengdu is stepping on SAC toe. Xi'an is not...

FWS-10 is the lifeline of Shenyang Liming. Where do you think Liming will be if has no more FWS-10 production contracts? Yet, SAERI designed WS-15 and WS-20 and they are going to be produced by Xi'an AE. There is a difference between the aircraft producing part of both base and the engine production part. But clearly, because you said so, Xi'an AE and XAC are the same thing. Shenyang Liming and 601 and 112 are the same thing.
