I meant nozzle instead of thrust chamber. You can blow both ends off the
solid at the same time, so that the resulting release of pressure from each
end (roughly) cancels out to zero thrust.



If you vent the upper end sideways (they were going to do this on the MOL/Dyna-Soar Titan III SRBs using two nozzles 180 degrees apart) the sudden pressure drop in the SRB causes combustion to cease.
