that answers nothing, he says "this design was very especial", "for angle of attack more than 20 degree especial design had been done" thats means absolutly nothing, i can show u a brick and say it fights airbattles better than a f-22 because it has "special design" but that doesnt make it true.
the physics says such as design will not work, does iran have magic to counter physics now? no one expects a full disclosure of the "special design" but even the most secretive militarys such as china and Russia have good reasons for their design choice and those reasons make sense without giving away sensitive info, they dont just go with "its a special design", for example, the russians say they use a radar blocking intake for their pak-fa to make up for the lack of s-curve intakes, it might not be the best solution but physically and (known) technology does allow one to do this. the chinese j-20 seems too large to be a fighter and has canards, but again the explanation makes sense, the tails are all moving thus allowing them to be small, making the plane seem large when in fact its comparable to the su-27 in size, the canards only maneuver during wvr combat where stealth has already be compromised
theres nothing in the mockup thats shows any solutions to said problems, and iran has not shown any technology that can overcome the limitations and problems. and simply saying the design reduces rcs alot also doesnt make it true. the j-20 has been modeled and simulated and shown by foreigners to be a true stealth design, and it follows all the known rules, such as smooth surfaces and general guildline of the reflective surfaces lining up. the f-313 does not follow these known rules at all.
further more there is the matter of capability, how many super computer does iran have to throw at the design? what sealth coating could iran even use? what is irans capability with regards to composits comapred to say, china, russia, USA? again for the 3 we have answers, we know china has engines production problems but we also know that china can test currently on ws-10 or al-31 engines(tuned for higher output but lower lifespan) and is putting in intensive efforts on ws-15 engines. whats iran got?
"we can't judge about them based on some photos or a short clip of it's mock up."
but in fact we can. there are shots/video of a person sitting in the cockpit giving us a relative size of everything, and it does not match up to what a real plane/mockup should be.
) However building a supercomputer in Iran case is a matter of money, hardware can be bought off the market, they can easily assemble several high-performance clusters. Distributed systems are widely used by educational institutions and companies around the globe.
