The invention relates to a method and device for controlling the mass flow rate of a sonic gas stream in a pipe. To carry out the above operation, an electric discharge is applied inside the pipe so as to create a plasma in the pipe. The electric discharge allows for an increase in the temperature of the gas stream and thus a variation in the mass flow rate or the pressure of the gas stream. By periodically emitting the electric discharge, a pulsed or adjustable gas jet is obtained at the outlet of the device. The gas jet can then be used to control a main stream.
