Zaphod, I think the word you were looking for is "splitter plate". It allows the intake airflow not to be perturbated by the boundary layer if I'm
Emile, for intakes you have different interesting systems to get optimized airflow, it often involves moving parts.
A nice example is the F-111A : it uses a moving cone in front of the intake, which moves back or forth depending on speed, and a part of the intake
itself can be moved forward for landing, creating a secondary intake for airflow, for landing and usually low speeds. There are two versions of this
intake, Triple Plow I (the entire intake goes forward) and Triple PLow II (three small inlets open) for later F-111 models :
Another explample is the French Mirages which use mobile "mouses" to help optimize the airflow, on the Mirage 2000 D and N these parts are fixed, as
a consequence their top speed is only mach 1.4 instead of mach 2.2 for the "2000 C" fighter version. You can note that the F-35 has "bumps" on the
fuselage inside the intakes, they can be compared to the Mirage "mouses", in my opinion, except they are fixed. Since they are fixed this could
limit the F-25 speed, on the other hand it seems that mobile mouses are a disadvantage for stealthiness, so having those bumps looks like an
I think the MiG-25 used moving plates inside the intake, quite like the F-14, F-15 I'd say. I don't know how one could tell which system is more
I'm not sure I answered you question but it was nice to write, anyway !
