This will suffice why IAF didnt go for Russian stuff for own fighters whereas Made in India engine was always desirable and was in mind, but.
But the Kaveri has not lived up to expectations either...even after working with the Russians and the French.
And eventually the GE-404 has come out as the choice. This also shows why the PAF does not yet trust the WS-13 engine as it too like the Kaveri is an advanced product from a beginner. refining both will take time.
Not just metallurgy, high temperature close tolerance metallurgical design and manufacturing is a different ballgame.
You have also mentioned one of the many reasons why I keep arguing pn PDF to form a closer alliance with parties such as USA to get tangible benefits like transferred technologies rather than just renting yourselves out as cheap mercenaries.
But we do that with the USA as well?? but that's besides the point.
Closer alliance with the USA has did not guarantee us ToT at an time.. even during those days when Jacky Kennedy was given a cheering welcome here and our guys got ticker tape parades there.
And as a general reminder.. the origins of the JF-17 lie in close alliance with the USA.
It was Grumman Aerospace that first proposed using a cranked double delta on the F-7 as part of the Sabre-II program, and I apologize if I am offending my Chinese friends here.. but the F-7E design.. the PG.. owes its existence to the Americans.
Mr Ma may have brought out those old "tablecloth" sketches and put them to actual use.. But it was US engineers that first proposed the idea of the improved F-7. Although that proposal never worked out for the sabre-II.. it led to Chinese and Pakistani ingenuity taking that seed of an idea and turning it into the fine product the JF-17 is.
They all still use the basic core.. the PW-100 is a modular engine.. one of the first of its kind.Depends on what engines you compare it, PW 100 are the old F16 engines, but RD93 is more comparable to the RD33-3 series engines, even a bit more modern. That means you must compare it with later versions of the F16 engine too.
The main difference is, that the F16 is a medium class fighter with engines that also powers heavy class fighters, while the JF 17 is a light class fighter, with smaller engines, that's why it shouldn't be surprising that the F16 is more costly to operate.
Do you have any data about the cost difference of JF 17 and F7?
Yes, RD33 for twin engine fighters, SMR-95 for single engine and RD93 is a varient of it:
Klimov :: Production :: Aircraft Program :: RD-33 family
Klimov :: Production :: Aircraft Program :: SMR-95
Compared to many of its contemporaries that have evolved into something different, the PW-100 is still as potent today as it was in the 70's.
It may be a powerful engine for its class but the RD-33 does not even come close to the refinement of the PW-100.
GE Engines used on the big-mouth F-16's have more oomph.. but those that maintain both usually prefer the PW-100.(not anymore with the F-100-229.. ).
The PAF F-16AMs fly with the F-100-220E.. and the Block-52's have the 229)
