My apologies if this is the wrong group. Please direct me to the right
one if it is.

I'm a mechanical engineering student who is interested in how the
intake system works on the SR-71. I've seen many articles on the
internet that mention it briefly, and give a simplified explanation,
but that's not what I'm looking for.

I'm looking for an explanation/description that's geared towards
someone who has a degree in mechanical engineering with a concentration
in compressible flow. If anyone could tell me of a place to find a
good technical description, I would greatly appreciate it.

The description that sticks in my mind goes like this:

The spike moves in and out to make the shock wave fall just inside
the rim of the inlet. The shock wave zig-zags down the annular
passage that bypasses the turbojet core, doing the ramjet thing.
Somewhere in the back, go-juice gets added to the now hot and
compressed air before it gets to the nozzle.

It's a very qualitative description, and I may have some of the
details wrong, but I'm not an aerospace engineer, nor do I play
one on TV, nor did I stay at a Holiday Inn Express last night,
so YMMV. :-)

yours,
Michael
