Ovo je pominjano ali definitivan odgovor zasto F-16 nose AIM-120 na krajevima krila a ne AIM-9 je sprecavanje flatera.
Citat:With all this in mind, I asked Lockheed Martin directly about this for a definitive answer. Here is their response:
The F-16 is able to carry different missiles on multiple stations at the same time, such as the AIM-120 and AIM-9. Because of that capability, the AIM-120 is positioned on the wingtip to reduce wing flutter, while still ensuring mission performance.
So, the wing flutter explanation is indeed the right one. This would explain why most F-16s fly with AIM-120 captive training rounds, which weigh 335 pounds, just like their live counterparts, on their wingtips regardless of the training situation.

Citat:Wing flutter is defined as "a dynamic instability of a flight vehicle associated with the interaction of aerodynamic, elastic, and inertial forces (aeroelastic phenomena)." Flutter has airframe fatigue and even performance impacts in particular areas of the flight envelope and can be minor to catastrophic in nature. If you have ever seen an armed F-16 taxi by you in person, the AIM-120s on the wingtips certainly bounce around, almost to a comical degree.

Iracki F-16 IQ ostaju bez podrske LockheedMartin osoblja:
https://www.nytimes.com/2021/05/10/world/middleeas.....artin.html
LM je do sada imao 70 svojih tehnicara u bazi Balad. Sada 50 ljudi povlaci kuci, a preostalih 20 premesta u bazu Erbil. Zvanicno objasnjenje je bezbednost osoblja.
Iracki piloti ne uspevaju da naprave dovoljan nalet, smatra se da je u ovom trenutku letno sposobno svega 10ak aviona. Uz odlazak LM osoblja iz baze, moze se ocekivati prizemljenje i tih 10ak letelica u veoma kratkom roku.
Alternativa je FA-50, ali i taj avion zavisi od podrske LM-a.
Ostale 2 mlazne opcije su L-159 i Su25, obe podzvucne.
Za L-159 ne znam kako ih Cesi odrzavaju, ali svi Su-25 su im trenutno prizemljeni zbog nedostatka rezervnih delova ili isteka resursa.
