INTRODUCTIONSpace travel is one of the most costly endeavors ever by mankind. It is made possible by the heavy rockets that power the space shuttle and the pay load into space. Since it is a costly process the efficiency of the propulsion system must be optimized. The present propulsion system uses bell shaped nozzles..Their efficiency is limited at low and high altitudes because of the changing atmospheric pressure. A possible solution to this problem is the new Aero spike engine.
