тут вот у индийцев один товарищ ругается
как специалист (если не лень) не могли бы прокомментировать, насколько это серьезная критика или же просто рассуждения пикейного жилета? Данный гражданин предъявляет претензии к расположению движков, отсеков вооружения и всего прочего и заключает с умным видом что сие не пятое поколение. Но индийское "министерство военных НИОКР" DRDO он смешно и верно обозвал - действительно попильная контора.
В целом же большинство отзывов индийцев ИМХО положительные, есть и восхищенные, подобные выпады в меньшинстве
Sorry to be the dampener here but it seems our beloved indian governments penchant for wasting money on poor design choices (or get railroaded into them by the russian our beloved DRDO (defence rejects and disasters organisation) comes to the fore here
1) Notice the engines
a) other than the basic oblique semi shielded engine placement (as in the su-27 and mig 29) there seems to be no obvious engine shielding of the JSF and JF-17 (one prototype) type. Someone on bharat rakshak has drawn a speculative ( and BR has for a while now been given to excessive speculation and flights of fancy - see their agni mssile page for example) flow of how they may be internally shielded BUT from this pic the wheel placement seems to block any neccesary width to allow for such a geometry
With the f22 while the intake geometry overlaps the engines the weapons bay placement right in front of the engines logically suggests total shielding see bottom left image in link below

b) the entire engine seems unsheathed top and bottom much like the current sukhois which means the IR signature will be significant. even the Mig 1.44 that came out 10-12 years back had better heat sheathing than this. This affects not just rear top and bottom stealth but radiated heat from the top and bottom will also creat a visible heat corona in the front approach
c) This plane is very obviously lacking some of the JSF's breakthrough features such as the conformal electro optical targetting system, the distributive aperture sub system, which means for ground attack it will have to carry external targetting pods and watching out for missiles and fighters in the rear will be manual and a major league pain in the posterior

d) the IRST is very obviously external and so obviously not stealth as is another bump behind the cockpit
e) take a look at this pic

i am simply astounded at the stupidity (and contradiction) of putting serrated edge bay doors (in this case presumably for the re-fuelling pod) while the quality of the jointing is of a most atrocious quality. Notice how many badly aligned screws are visible and even in this lowish resolution image their lack of flush alignment is all too obvious. Its a bit like montserrat caballe wearing black cuz she thinks it looks " slimming" on her - FAT CHANCE LADY!!!
presumably such shoddy finishing carries on on the rest of the plane as well
truly a case for " for want of a nail the kingdom was lost"
f) A further conntradiction is the limited rear visibility when
1.1 the lack of a rearward DASS array mean the back is basically a fully blind spot
1.2 built in supermanouverability added to unrestricted rear vision could have been a symbiotic plus
g) IMHO this is merely a superficially fifth generation grand stander. The true under the skin, construction, finish challenges of fifth gen have not been met
