  • Nozzle Design - an overview

    The nozzle design generally follows the same ablative approach as the solid motor but with one caveat. An aluminized solid propellant usually operates in a low-O/F regime where I sp is maximized. In this region, where the combustion gases contain a low concentration of oxidizing species (such as O 2, OH, H 2 O, CO 2), graphite nozzles perform well, showing low erosion.
