Popov Institute of Applied Mechanics of the RAS, Moscow, Russia Authors experimentally investigated set fire of hydrocarbon fuel and air mixture supersonic stream with electric discharge. <...> Discharge parameters and set fire time were defined. <...> It is shown that average electric energy is less then kinetic stream energy more than 5 orders. <...> Experimental results confirm theoretical models of different authors. <...> Показано, что средняя энергия, вкладываемая в поток поджигающим устройством, более чем на пять порядков меньше кинетической энергии основного потока газа! <...>
