   Has anyone ever designed/built a hybrid jet-rocket (not a scram jet, but hey   
   if it scrams too then thats neat :)   
      
   I was thinking something along the lines of an external combustion rocket   
   nozzle, with a conventional turbofan jetting concentrically down the middle.   
   The turbofan could be used to power the pumps for the rocket fuel. Both   
   Burning LOX Kerosene in vacuo, the Turbofan burning air/kerosene on return   
   to atmosphere.   
      
   A quick check on google shows no such hybrid.
