Hey all,

May have a go at IDEAS 24, if you have any questions, post here, will give it a shot.

Thanks
Inquire if JF-17 could ever change engine such as to Chinese WS-21 or even WS-19.

Also consider Russian SM-100 has thrust to weight ratio of 8 to 1 while if there was afterburner thus over 10 to 1 ratio thus two SM-100 could be effective replacement of RD-33/RD-93 while improving safety since probability of both engines malfunctioning is far smaller than for single.

Two SM-100 if they had afterburner would generate 11 ton force of thrust compared to 8.5 ton force for RD-93 thus former 30 percent greater thrust.

Sorry my overenthusiastic friend, but the SM-100 - even more so for the JF-17 - is at least for now more a paper-project than real hardware stuff!

I would love to know if the rumours, some JF-17Cs are indeed using the RD-93MA and later the WS-13 are true.

@Deino Rumors regarding the RD-93MA are not true; none of the JF-17C aircraft utilize this engine. The Air Force is not very pleased with the RD-93 engine, especially considering that the recent crash of the JF-17 was due to an engine flameout over the gun range in a relatively new Block 2 airframe. There have also been issues with the smooth supply of spare parts due to sanctions on Russia, coupled with their consistently unreliable supply chain.
Currently, they are trialling the WS-13E engine; however, they have encountered a few snags that are being addressed.
You might ask for a source regarding this information, but I can only say that it is insider information.

Thanks a lot, the WS-13E part is interesting, since it fits the same I heard also from an insider. On the other side exactly my "insider" told me, at least a few JF-17Cs were delivered with the RD-93MA ... and here too: "You might ask for a source regarding this information, but I can only say that it is insider information." ;)

It is not a paper project. Salyut was assigned the task of cloning the Al-222 for the Yak-130 to remove the dependency from banned Ukrainian imports. After Salyut did that they made a plan to modernize the engine. They are progressively replacing all the components in it to make the SM-100. The Al-222 is modular so you can replace the components in it one by one. So yes the engine is still not available but it is an ongoing project.

Then maybe I misunderstood him ... I read his post as if the SM-100 "could be effective replacement of RD-33/RD-93" And that's impossible.

SM-100 is meant to be used in the Yak-130M. He is just speculating.

From what I understand engine basic design is complete and they are at the stage of component subassembly testing.

Currently, the low-pressure compressor and turbine are undergoing bench tests, while the combustion chamber is undergoing flight tests.
In addition, a modernized high-pressure compressor, which has become smaller and lighter and cheaper to produce, will also be tested in the near future.

He basically wants to replace the JF-17 with a lightweight twin engine fighter. I think the main issue with the SM-100 for that application, once it is available, is that as far as I know no afterburner is planned for it. Although there were versions of the Al-222 with it.

“In their creation, technologies and materials characteristic of the fifth generation engines are used. The SM-100 engine is designed in the dimension of AI-225-25 and at the same time has less weight, as well as thrust increased by one third – up to 3300 kgf. New design solutions allow to significantly increase the engine life with reduced thrust requirements, which reduces operating costs. Moreover, a modification for high-altitude unmanned aerial vehicles can be created on the basis of the SM-100 engine,” the press service of UEC said.

Also shown was the modernized RD-93MA with an extended operating life and a thrust increased by 400 kgf, which is 9300 kgf. This engine was developed at UEC-Klimov to power the JF-17 Block III fighter aircraft developed by Pakistan Aircraft Complex (PAC) based on the Chinese JF-17 of Chengdu Aircraft Corporation (CAC). This version of the aircraft has been in serial production in Pakistan since December 2020 and is equipped with an AESA radar, RD-93MA engine, larger and more advanced wide-angle cockpit display and electronic warfare capabilities.

For example Hongdu JL-10/L-15 uses AL-222K-25F engines and SM-100 with same afterburner section as former or redesigned one would be generational leap in thrust output at over 1.0 thrust to weight ratio at current rated maximum takeoff weight along have more output than JF-17 Block III with RD-93MA by 1700kgf.
