THE INSTABILITY OF PHYSICAL FIELDS IN THE LIQUID-VISCOUS LAYER DURING THE BURNING OF ENERGETIC MATERIALS
要約
The development of a new generation of solid propulsion systems with high energy characteristics, featuring a reduced boost phase, has led to a renewed interest in the prevention of combustion instabilities and burning anomalies of energetic materials (EM). In the last few years, researchers have observed the excitation of the spatial periodic micro-structures (SPMS) and the presence of micro-torches at the burning surface of EM. Both experiments and theory confirm that the SPMS excitation is a rather universal phenomenon. Many arguments have emerged, suggesting a dominating role of condensed phase processes for a number of common homogeneous propellants. The present work focuses on one of the critical events, namely the SPMS excitation in the evaporated EM liquid-viscous layer. The presumed mechanism of the SPMS excitation in the evaporated EM liquid-viscous layer opens the possibility of understanding the burning of EM on a new qualitative level. In this paper, the EM decomposition is analyzed using new principles. Without understanding the excitation mechanism of the cellular micro-structures on the EM burning surface, it is impossible to understand the phenomenon of "negative erosion." Previously, "negative erosion" was considered for atypical conditions for excitation of cellular micro-structures. An additional task of this research is to confirm the existence of a cellular micro-structure in the EM burning wave.
