Something is funky, to say the least.
The nose is too small to have any radar larger than what the highway troopers uses to catch speeders, for starter.
Weapons bay -- allegedly -- is too clean. Anyone who has ever flown or worked on aircraft, civilian or military, know that internal volume space is a premium and in landing gears and weapons bay, there would be wiring bundles and pipes of every sort running through. On a real aircraft, when the landing gears are up and doors close, there would be literally fingers breadth between tire and a wire bundle or any mechanical doo-dads.
That cockpit...If this is a visual representation, then why bother to have an allegedly functional canopy because that cockpit well size is suitable for children, like Disneyland rides.
Sorry to the Iranian members here, but I have no choice to cast serious doubts on the validity of this. When the J-20 was rumored, I advised all to take caution until we see something more definitive. Then the Chinese surprised everyone with rolling field runs and eventually a flight. The Chinese had no intention of impressing anyone with any teaser photos. But Iran have been very vocal with one new weapons system pretty much on a monthly basis with nothing else to back up each one.
