Abstract

The ejector ramjet is a rocket based combined cycle propulsion system in which a rocket and ramjet are integrated to accrue synergistic benefits. A proof-of-concept experiment to augment the thrust of a simulated rocket by the induction of air through an ejector and the subsequent afterburning of kerosene fuel in it is described. Ejector ram-jet thrust augmentation ratios of up to around 1.1 at the simulated take off conditions have been achieved. The critical effect of the operating conditions and the ejector ramjet geometry, in particular the afterburner configuration, for achieving thrust augmentation ratios greater than one have been demonstrated.
