Matryoshka diagnostic system, could take inlet and engine's 1st stage blades imagery for remote inspection?One obvious limitation of this inlet design is access to the front of the engine for pre/post flight inspection for FOD damage. The shape of the inlet does not appear to be big enough for personnel entry.
For US fighters, the crew chief typically crawls into the intake and visually inspects the engine 1st stage blades for damage. I don’t see any provision for the Russian FOD screen / alternate intake seen on the MiG 29 or SU 27 aircraft. Remote imaging via borescope is a possible low airframe volume solution, but this requires expensive equipment to be readily available for every inspection and is typically not a quick process
Or, they just don’t do the inspection and accept a number of engine failures due to undetected blade damage….
