For more than ten years, solid micro-propulsion has been an active world-wide field of research. In the combustion chambers of the solid micro-propulsion systems of the small-sized orbital maneuvering vehicles, the scale factor has the significant influence. In this connection, the micro/nano- structures arising in the energetic material reactionary zones has a large influence on physical and chemical processes and on controllability of ignition and combustion processes. The analysis of experimental data shows that in a number of cases, the macro-scale phenomena at the energetic material combustion are result of self-Organizing of the micro/nano- structures in the reactionary zones. In the Issue the new hypothesis of excitation of some combustion instabilities, that are connected with Self-Organizing of the micro/nano- structures in the reactionary zones will be discussed. This phenomenon is universal and can be understood within a common framework based on modern nonlinear dynamics. The new possibilities for effective control by ignition and combustion processes opens in connection with possibility of initiation of self-organizing of the reactionary zone by use of the electric fields and the electric discharges. Self-organizing of the reactionary zones is essentially new level of self-organizing which is determined by achievement of critical special concentration of the micro/nano- structures.
