Abstract: The influence of the space-time characteristics of a pulsed energy source on a supersonic flow through a divergent channel is considered. It is found that low-frequency energy sources used for generating the thrust may provide a considerably higher specific force than continuous energy input. The influence of the duration of periodically applied energy pulses on the specific force is shown to be nonmonotonic. Short pulses provide a much higher specific force compared with steady energy input. The nonuniformity of the energy input distribution along the channel is found to have a noticeable effect on the specific force.
