   I looked on the web curious about thrust augmentation concepts for jet   
   engines and found a 1952? NACA report that detailed an experiment where   
   water was injected into the combustion chamber to increase mass flow and so   
   thrust.   
      
   However, the water and fuel were injected separately and the researchers   
   limited themselves to only adding 20% (I think) water because they thought   
   it would start interfering with combustion stability or something.   
      
   Has anyone heard of any research into pre-mixing the water and fuel together   
   to avoid this problem?  Or any other similar research like running jets on   
   water-alcohol fuels, or water-oil emulsions to achieve the same effect.
