The most complex ones that I worked with were the F-111 and the B-70.
We tested inlet/engine combinations in the PWT Supersonic Wind Tunnel
(16x16x40ft test section) to determine inlet performance at various Mach
numbers. The desired characteristics of such inlets are high pressure
recovery and freedom from inlet unstarts (where the shock system is
expelled from the inlet).

Many supersonic jet aircraft have some system like that, Chris. Normally it
takes the
form of a movable ramp inside the intake, but some aircraft, such as the F16,
use another
device. I am guessing but it is probably the shape of the passage between
intake and the
front of the engine, although I rather think that the F16's shape does the
trick of
arranging for the shock wave to remain ahead of the intake, so keeping the air
into the
engine subsonic.
Yes, and the F-102 and F-106 had a half-cone at the intakes that
performed the same function.
