The paper deals with the problem of increasing the speed of propagation of the flame front as applied to the problems of reducing noxious emissions of nitrogen oxides formed during operation of jet engines and industrial turbines, as well as the stabilization of a supersonic combustion. We investigate the possibility of reducing the induction time using non-equilibrium cold plasma produced by an electromagnetic vibrator in beam quasi-optical MW radiation. The positive effect of cold non-equilibrium plasma on increasing the rate of occurrence of oxidation reactions in the air is well known and undisputed. The presented results of the experiments demonstrate the advantage of the method developed in terms of efficiency and suppression of nitrogen oxide emissions. Also they show that combustion stabilization is achieved similarly in a supersonic flow.

Keywords: gas dynamics, quasi-optical microwave radiation, cold non-equilibrium plasma, supersonic combustion, emission of nitrogen oxides
