No. The scenario is that we are predominately generating the *pressure* 
by the centrifugal pumping action. The propellent undergoes an 
exothermic chemical reaction in the tip rocket liberating gaseous fluid 
that exits through a De Laval nozzle.

Clearly there is something impossible in the problem description; 
otherwise there would be no paradox. The puzzle is: "what is wrong?"
