JF-17 Thunder Multirole Fighter [Thread 4]

[[--Leo--]]

i don't think that there is any eminent upgrade of engine ,
according one source we are in discussion with russia to provide us with latest series of these engines that have TVC and thrust of about 100 kn

which source?can you post the link please

What are the implications of the 200% load test? I am assuming it is dynamic loading they did. I assume they will add another tonne or two of payload? I.e. 5 tonne or 6 tonne carrying capacity. … … and the engine is being uprated. This is all good news for the fighter.

or they could choose to split the extra “strength” and use some to add tonnage and then some to add life (fatigue).

Hi,
Can you see the pictures posted by nabil_05?
Can you tell if the engine is same old rd-93 or something different?
As ws-10 is long awaited and long delayed...
May be the load test was for ws-10?

From the exhaust nozzle engine looks the same in both pics. I don't think there is going to be any change soon in the engines as Chinese version will take 5/6 more years to develop/mature. There is no other viable optiion available at the moment except of upgraded RD-93MA, which if developed, would need approval from Russian government.

I think GOP should launch an open program to build jet engine..
a 60 year old technology shouldn’t be so impossible..

I don't think it would be comercially viable to manufacture jet engines at this time. I would rather like to see PAC increase the number of parts manufactued in Pakistan from Pakistani produced materials specially frame.

There is one thing which confuses me, we know that we don't have any wind tunnels to test air frame aerodynamics, but on the other hand we have many private concerns who are engaged in manufacturing high speed target drones, how and where do they test air worthiness of their models? Do they make their own designs from scratch or are they too just assembling them fromimported CKD's?

If they are capable of designing their own models, then perhaps PCA can form some kind of JV with them to atleast try to design a successor design of Thunder.

JFT target by 2014-15 is 80% local parts.

What are they going to do about engines?

What are they going to do about engines?

continue with russia via china until chinese engine matures - time-line 3-5 years

^^ India will do all they can to stop,disrupt the supply if engines...
Thats an uncertain strategy for Pakistan...

A noob question, if anyone's up for it :

How hard is it to reverse engineer an 'engine' when you're already at the brink of creating a domestic one ? Which is to say could Pakistan allows the Chinese access to some of the F-16 engines that we have for them to make notes about it, to compare its performance with the desired performance of the indigenous Chinese one & to consequently identify improvements from the former to be implemented on the latter ?

I don't know why people on forums are so interested in engine only. May be its just a point of discussion for you guys. The current engine is doing great, PAF is happy with it. Plus, some tweaking with their basic design has increased their performance and reliability. The current needs of JF-17 is full filled by the current engine. It generates enough power to perform well even with greater weapon load. New engine discussion would be required when Block-III will commence, till then necessary tweaking and refinement in current engine is enough for PAF.

not a good idea.

this is not an issue anymore!

Sir its not the engine itself..
Its how and from where Pakistan gets it....thats the problem.
The whole point if jf-17 was to give pakistan an embargo free jet fighter..
Niw RD-93 is prone to delays and all out blockade at any time...
This doesnt match with the purpose of jf-17 program..
Thats why engine is pointed out always..,

 

[Gin ka Pakistan]

Why China is not interested in JF-17 ? or they have a plan to induct them in the future

thats your own assumption
