Now the world is moving closer to the other planet. As we are searching for the new planets for living we had found that rockets are the only way capable to take the people from earth to the different planets, so scientist and engineers are focusing more on new rocket design which will be more efficient and more powerful in future, for example SpaceX company have rocket model SN 8 which have ability to take the humans to the mars. In rockets, the nozzle used for exhaust the gases at high speed which produced by the combustion of propellants. Today we have different type of rocket nozzle like conical, bell or convergent divergent nozzles. In this paper we will discuss about the convergent and divergent nozzle design with varying inlet and throat area or throat area ratio and will seethe variation in aerodynamic parameters and analyze all three designs on the ANSYS software which is computational fluid dynamic software. In rockets, convergent divergent shape is mostly used as nozzle which is also known as de-laval nozzle.
