First, I start by saying that I have no desire to insult you or offend you in any way, but I just have to speak based on my knowledge of engines and my decades of experience at RR.
To compare J79 to AL21F, is a total utter nonsense. The GE engine is a 2nd gen engine, the Russian engine is a 3rd gen engine. They weight the same, although GE is 17/11 and the AL is a 24/17 (afterburner vs military power). The only thing I like about the GE engine is the PCC (pre-compression cooling with distilled water and oxidizers for higher altitude flight, e.g. 80,000 ft). Other than that, it is like comparing a Ferrari to a Ford.
Ignition box temp increase ???? umm. Sorry, this does not work on me. It's armature talk.
Even if Iran added single piece frontal fan to reduce the noise, even if they used blisks (2018 implementation technology) with blade temperature reducing covering, even if they used the most advanced combustors and low turbine stage, it is still the single spool J79 is a J79 and will always be a J79, with huge limitations. This was the most advanced engine of 1960s. That's all.
Compressor blades itself (without re-engineering of flow) cannot be modified to give a huge air injection for a worthy performance increase.
I am sorry, you are talking total utter nonsense. I hate to say anything that may insult someone on this forum. Not my style, but I just have to say how ridiculous your post is, in terms of reality and engineering.
Please don't hold that against me. I am just trying to be helpful.
I personally don't think much of either engine. I much prefer R35 (in Mig 23) with a frontal fan connected to the power source of the engine to generate a flow (momentum air displacement) with variable nozzle before it enters the front of the engine, this creates air flow momentum and using bleed sensors, reduces fuel consumption (somewhat, better than .98 lb/lbforcehour) - this technique is what U.S. implements with its engines in some of its stealth aircrafts.
With respect.
