Propulsion study of a self-propelled vehicle

Abstract

Travel to space in the last decades has become a race for the powerful countries. Nowadays developing rockets and all its accessories is of major importance. For completion of such projects, it is required to study propulsion, aerodynamic system and many aspects of the vehicle. Rockets can have different shapes and internal compositions. In this work, we chose the different components that constitute the propulsion system through calculations and simulations. We designed a propulsive system for a space vehicle and compared between a showerhead injector and a pentad injector to highlight the importance of having an efficient injector in a rocket thrust chamber. The thrust and other properties calculated theoretically at first failed to be reached by the simulations of the showerhead injector and were successfully attained when a pentad injector was tested.
