Abstract : This note presents equilibrium thermodynamic data, in graphical form, for the H2-O2-He system considered as a possible high enthalpy driving gas for hypervelocity applications. The weight formula of the basic system is expressed as (2H2 + O2) + m H2 + n He, and molar dilutions of the stoichiometric hydrogen-oxygen system up to 67% are envisaged. For these mixtures, composition data, thermodynamic data and relevant partial derivatives are given assuming thermodynamic equilibrium, for temperatures ranging from 2000K to 5000K and pressures from 0.01 to 10,000 atm. More specifically, these data include mole fractions, molecular weight, enthalpy, density, logarithmic first partial derivatives with respect to temperature at constant pressure or with respect to pressure at constant temperature of molar fractions and molecular weight, equilibrium specific heat, isentropic exponent, and equilibrium and frozen speeds of sound.
