Abstract : The essential features and the performance to a flight Mach number of 4.5 are compared for three combination engines based on three existing turbofans. The turbofan and ramjet in an combination engine are mated in one assembly; the turbofan is located in the center of the powerplant and the ramjet is built around the turbofan. The combination engine is fed through a single variable geometry air inlet; all flows are ejected to the atmosphere through a single variable geometry exit nozzle. The direct ramjet flow is mixed with the secondary flow from the turbofan; this flow mixture is fed into the annular combustion chamber. The consequent effects of turbofan-ramjet interaction are important. (Author)
