Comparative Study of Kerosene and Methane Propellants for Reusable Liquid Boosters Stages

Abstract

Kerosene and methane are two promising candidate propellants for a future reusable booster stage. This study assesses the merits of both propellants and compares their respective performance when used in a booster stage. The identification of the propellant properties is the starting point. An analysis of a staged combustion cycle engine for both propellants follows. The final assessment is based on the results of a performance analysis of a launch vehicle making use of these motors in reusable fly-back boosters.
