Regarding the air intakes you are not correct. The F-22 uses F-15 style movable ramps for shock generation unlike the DSI of F-35 and J-20 which doesn't have any moving parts and is simple.View attachment 74719View attachment 74720View attachment 74721
After seeing this scale model I think this is a pretty good Stealth Design , Nose section is very interesting - better stealth , good airflow for engine , better stealth from sideways. The air intake structure( side ways) much similar to F22 and offers better stealth features( unlike that shitty J20 ) top section also offers better stealth from AWACS which searches from above .
No EOTS , two patches in the nose section indicates may be Some sensors like cheek mounted Radar , No IRST , The HySIS spectral imaging satellite can directly feed into AMCA so it will get EOTS&IRST like sensor support without sensors , probably they will be added in the MK2 or may be it is already there .
Think they want a super Stealthy Aircraft without any protruding surfaces , May be better stealth than F22 & F35 if we use similar materials like of 22&35 .
Only time will tell how good it will be. Some people are disappointed that it doesn't look much fancy and immediately concluded it is not upto the mark , no words for those .
F-22 uses such a ramp structure with diverter plates and intakes because of its higher top speed . DSI are simpler ,weigh less and doesn't need a lot of maintainance . That's why Su-57 used ramps in the inlet instead of dsi because it also has a Mach 2.0+ max speed and higher supercruise speed. When you need that extra performance you need to focus on the minor details . And Su-57 isn't what most Western fanboys and F-22 and F-35 experts allege it to be .
DSI offers you mediocre performance at higher speeds unlike the variable ramps. It's all about what you want your ac to do and the tradeoffs required to accomplish the same.
