Dear,
I don't want to fight you over this but RD-33 basic had MTBO of 300 hours, which was improved to 1000+ for series 2 and 1500+ for series 3. RD-93 shares its MTBO with series 3, since its reported life-cycle is of 4000hrs with ~1500 hrs MTBO.
Regards,
Sapper
who asked you to fight me over this . there is nothing to fight over the truth .... please quote me one source that says rd-93 is derived from RD-33 series III engine
The FC-1/JF-17 is powered by a Russian-made Klimov RD-93 turbofan jet engine rated 49.4kN dry or 84.4kN with afterburning. The RD-93 is a derivation of the RD-33 used by the MiG-29 fighter. In 2007, China signed a contract with Russia to supply 150 RD-93 engines for the JF-17 production.
Liyang Aero Engine Corporation in Guizhou is reportedly developing an indigenous turbofan engine designated WS-13 (or Tianshan-21) as an alterative powerplant option for the FC-1. The engine was said to have been based on the RD-93 design with some modifications.
Are chinese using this WS-13 engine on any other plane rather than JF-17 ??
Since it is not a nice idea to use JF-17 as a test bed alone ..
The RD-93 is a derivation of the RD-33 used by the MiG-29 fighter not RD-33 series 3.
RD-33 series 3 is version of RD-33 for model with a longer service life used on later or upgraded old variants of the MiG-29 such as MiG-29M and MiG-29SMT. A pair of RD-33 series 3 engine equipped with TVN is currently undergoing flight tests as a component of the MiG-29OVT jet fighter.

Sapper's point is not wrong abt MTBO (Mean time between outages)
I have a question if taxi trails have already been taken place with ws-13, this means what ever modifications were required to accommodate a new engine has been already done.
My question is from this stage how long will it take for the WS-13 to fully equip the next batch of the JF-17s and secondly what are the parameters/benchmarks that are kept in mind before installing a new engine on a single engine jet.
Salman since you are an engineer perhaps you can enlighten me on this one.
Thanks
what u mesa by the word taxi trail.idiot Haanzo
jf-17 is much better that tejas. this is not i m saying but France & Russia said
10% more thrust means how much more speed we are talking about. Current max speed is stated as 1.8 with RD93, are we talking about crossing mach 2+ with 10% more thrust, can someone point comparison of WS13 and RD93 with their dry thrust and max thrust?
China is copying way less now than say, 10 years ago, because China has already learned most of the Russian techs anyway. There is no more benefit copying Russian stuff.
