USE OF A RESONANT VIBRATOR POSITIONED PERPENDICULARLY TO THE OPTICAL AXIS OF A COMBUSTION CHAMBER FOR AMPLIFICATION OF THE ELECTROMAGNETIC FIELD IN IT

An electrodynamic model of a combustion chamber, in which a combustible mixture is ignited by a suberitical streamer discharge initiated by a vibrator with the use of a microwave radiation, is presented. For localization of this discharge in the combustion chamber, its initiator (vibrator) is positioned perpendicularly to the optical axis of the chamber. The possibilities of amplifi cation of the electromagnetic fi eld at the poles of the vibrator in the case where a microwave radiation is introduced into the chamber with the use of a plane horn and in the case where a planar waveguide is used for this purpose were considered. Numerical calculations of the electric fi eld in which a subcritical streamer discharge is formed in a combustion chamber have been performed with regard for the geometric parameters of the initiator of this discharge. The ways of amplifi cation of the resultant electromagnetic fi eld in the region of disposition of a vibrator in a combustion chamber were determined for the purpose of obtaining a subcritical streamer discharge with a volumetric structure in the chamber
