Abstract
Results are given of experimental investigations of the combustion of a supersonic air-propane flow, initiated by a longitudinal-and-transverse dc discharge, in an aerodynamic channel with a backward-facing step. Several modes of combustion are revealed, which depend on the initial conditions associated both with the discharge parameters such as current, duration and so on and with the parameters of supersonic flow such as initial pressures in the systems for delivery of air and propane, initial pressure in the ballast chamber, and the relation between the times of delivery of air and propane.
