This paper discusses a study of two alternate oxidizers, liquid oxygen and hydrogen peroxide, for use in a rocket based combined cycle (RBCC) demonstrator vehicle. The flight vehicle is baselined as an airlaunched self -powered Mach 0.7 to 7 demonstration of an RBCC engine through all of its air breathing propulsion modes. Selection o f an alternate oxidizer has the potential to lower overall vehicle size, system complexity / cost and ultimately the total program risk. This trade study examined the oxidizer selection effects upon the overall vehicle performance, safety and operations. After consideration of all the technical and programmatic details available at this time, 90% hydrogen peroxide was selected over liquid oxygen for use in this program.
