Working Fluid modeling Based on Air Turbine Rocket Engine and Propellant Comparative Analysis

Abstract

The propellant of the Air Turbo Rocket (ATR) engine is burned in the gas generator to produce primary gas. This paper uses the established ATR engine working fluid calculation model to calculate the physical parameters and components of the primary gas produced by the combustion of four propellants at a given pressure and temperature, and compares and analyzes them according to the propellant selection requirements, Choose the appropriate propellant for the ATR engine.
