And here is a chart showing the temperature, pressure and velocity of
the gas flow in a turbine engine, the J79.

Okay, here's a basic (probably dumb) question:   Notice that the pressure in
the middle of the combustion section is higher than the pressure at the
entry of the combustion section.  Given this, why doesn't the gas flow
forward (to a section of lower pressure) to the compressor section?  Is it
maybe the fact that "pressure" shown in the chart is "static pressure" and
that the static pressure PLUS the dynamic pressure of the gas moving aft
into the combustion section is higher than the static pressure in the
combustion section, thus the gas keeps moving aft?

You guys are hard to train.

There are no dumb questions. In fact that is an excellent question.
Gases have velocity, mass  and inertia, not shown in the diagram,
that also explain their behavior.

Ram jets and SCRAM jets work in exactly the same way.
