   Back in freshman physics the large lecture   
   hall was filled to direct students to the correct   
   curriculum.  One class was the old mass thrust   
   theory.  If you could not follow the theory you   
   were directed to a non-physics department.   
      
   I still wonder to this day.  I believed it was more   
   complicated than stated.  There was a function   
   of rocket mass change with time.  And a constant   
   fuel mass burning giving thrust. A fuel mass velocity   
   equates the theory.  Assuming a constant throttle.   
      
   My question was the true efficiency of fuel mass   
   to thrust.  The internal chamber structure is my   
   question. How would a flat plate engine design   
   differ from a the chamber? Begging the question,   
   how do chamber designs converge to the most   
   efficient?   
      
   I figure that maybe the hottest engine is the most   
   efficient.  Making the idea that a thermal defect   
   exists.  This is energy radiated not effecting   
   thrust.  This is of course small compared   
   to chemical thrust.  But it does introduce the   
   concept of chamber internal dynamics.   
   How would a straight tube chamber differ   
   from the normal cylinder with nozzle?   
   And the exact location of the burn in the chamber   
   be calculated?
