Simplified Method of Calculating Ram-Jet Performance Applicable to High Mach Numbers

Abstract

The method presented permits rapid calculation of ramjet performance and still incorporates major effects of molecular dissociation in combustion process and variable specific heats of air as well as of products of combustion. Variables, such as diffuser, combustion and nozzle efficiencies, and operating factors, such as velocity of air at entrance to combustion chamber and fuel-air-ratio, can be assigned any value considered practical for purposes at hand. Sample calculations are included.
