I know exactly what these are for. Example: On the Grumman F-14/D Tomcat, there's whats called "bleed air ducts" on top of both intakes. At supersonic speeds, the vents open up because more air is going into the intakes faster than what the Twin General Electric F110-GE-400 turbofan engines can process. It'll cause a stall if the excess air can't escape prior to going through the engines at supersonic speed.
On the Mada' going at subsonic speeds, too much air going into the CAI can cause the 5.6 to stall so some of the air must bleed out thru the vents on the fenderwell that you see in the pic. Try breathing normally sticking your head out the window at freeway speeds and you'll know what I mean. You'll have to cover your nose to slow the air down to breath.
Now you know I'm blowing smoke about the latter right? Don't want to get flamed.
Gunslinger could be right!
YA know how when you're sitting in the cod with the door open and the props spinning how the pressure sort of thumps in the cabin? The exact same thing happens in the Armada with the windows open and the speed brakes closed (rear vent windows). The Mada's have the same little overpressure vents as the Tomcat but they are underneath the back at the bottom of the fender panels. And they work just about as well too...
