Why is it constant volume?.The shock wave travels from the closed end of
the tube to the open end. After the shock-wave the pressure rises a
lot, this higher pressure is pushing on the closed face of the
tube producing thrust. Now the detonation wave travels faster than
the

One small thing -- of course, pushing on the closed face of the tube
isn't what causes thrust.
