In this study, multiple detonation tubes are directed into a single ejector in an effort to reduce the added hardware required while maintaining the level of augmentation. By moving a single driver off axis it is found that the augmentation level can be maintained for x/d less than 4 and y/d up to at least 1.14, for a round ejector. The ejector augmentation, however, is found to decrease by about 25% during multi-tube operation, being approximately 1.3 ejector to baseline augmentation ratio. A linear arrangement of detonation tubes is constructed extrapolating typical unsteady ejector parameters. Four linear detonation tubes are directed at the linear ejector and the highest ejector augmentation ratio is 1.25 even with reduced fill fraction. With single tube operation, the performance of the linear ejector is at best 1.15, indicating multi-tube effects are significant.
