In this report, the various definitions of inlet efficiency, which are currently in use for supersonic combustion ramjet engines, are surveyed. Derivations of each of these parameters and the relationships between them are presented. Charts for the conversion from one parameter of efficiency to another are included. These charts are based on real gas properties. Attention is drawn to the application of available energy concepts to the supersonic combustion ramjet engine, and a definition of inlet effectiveness is introduced.
