Znaci konkretnih odgovora, kao ni bilo kojeg izvora za to sto ti pricas nema. Zali boze gubljenja vremana na rasprave sa spinerima poput tebe.

Konkretne odgovore si dobio , a to što tvoje intelektualne mogućnosti ne dozvoljavaju da ih razumeš nije moj problem .

Jbg izgleda da nisam jedini kojem intelektualne mogucnosti ne dozvoljavaju da pojmi to tvoje isprazno trtljanje. A u svemu sto si ti napisao nema nikakvih konkretnih odgovora, kao ni bilo kakvih izvora koji tvrde isto sto i ti.

mean_machine ::Po meni dva vrlo dobra posta na temu doprinosa povecanju odraza:
defence.pk/forums/air-warfare/117976-ex.....ost1910717
defence.pk/forums/air-warfare/117976-ex.....ost1917174
Drugi post je inace napisao bivsi pilot F-15.
Lepo čovek kaže da je prva aproksimacija RCS naoružanog aviona sabiranje RCS aviona i pojedinačnih raketa/bombi . Nema tu mnogo iznenađenja kad se gleda prednja polusfera koja je najvažnija na avionu . Tek sa strane nastaju interferencije koje mogu da kumulativno uvećaju RCS .
Actually...It is very much like that. We effectively sum up all the individual RCS and perform full scale model radar testing. Sometimes the results surprised us because of unexpected destructive interference that give us a lower final RCS value than anticipated. Sometimes the results are greater so then it is back to the proverbial drawing board we go. Some designs may not give us the option of re-doing our work because any changes could catastrophically compromise aerodynamic necessities. Like it or not, aerodynamics comes first.

A privi deo si uspesno preskocio:
Citat:It is very very considerable and the JF-17 is no exception no matter how much anyone wish otherwise. DO NOT be misled by individual RCS values. Item three as I stated above can CUMULATIVELY make all the missiles, the bombs, the external fuel tanks, and the pylons that carries them as large an RCS value as the aircraft itself. Perhaps even greater.
Since the debut of the F-117, manufacturers are busy trying (with little success) to reduce the contributorships of externally carried stores. The problem lies with the second item I said above. The more protrusions you create, the more the complex the body and the greater the third item.
A preskocio si i pisanje pilota, jer ti valjda ne odgovara sta je on rekao:
Citat:When external stores are hung, huge areas of return form between the aircraft, pylon, and store. In particular, almost all aircraft external stores have "fins" of some type, and by placing a fin right next to an aircraft, even that small area creates a 90-degree reflected bounce. This also occurs on the fins of the missile or bomb itself.
Citat:Even tiny corner reflectors make a powerful signal. For aerial gunnery training, a plywood target is put together, and so it can be seen on radar, a single aluminum sheet corner reflector is bolted on the back. This device is only 1/2 a meter across, yet can be locked up like a B-52.
Again, in simple terms, if it looks busy, jumbled, and it's metallic, then it'll be reflective.
The fins on this AIM-9 alone could be seen at great distances by modern radar.

Ti si osim što si glup izgleda i ćorav , kad ne vidiš da se to odnosi na RCS sa strane i pozadi :

RCS se meri sa svih strana, a oni onda prezentuju taj najmanji iz prednje polu sfere i to kada je avion nenaoruzan. Jel to postoji neko pravilo da ti smes protivnicki avion napasti samo iz prednje polusfere, i ozraciti ga samo pod uglom koji njemu odgovara?
