I have some questions about
variable air intakes for different fighters.
Why are they needed?
Which one of these have variable intakes?
F-4, F14, F-15, F16, F-18, F-18E, F-22, F-35
Rafale, Typhoon, Gripen, Tornado, Mirage 2000, Viggen
Mig-21, Mig-23, Mig 25, Su-27 family, Mig-29
Thanks in advance.
edit: oops, forgot to put the word "variable" in the first question. I was thinking a bit too fast for my fingers to follow.
