本文详细分析了有机和无机添加剂、壳体材料和样品截面尺寸对二硝酰胺铵(ADN)燃烧行为的影响。尽管ADN是一种氧化剂，但可燃环境对ADN压坯的燃速几乎没有影响。相反，少量的有机和无机混合物对ADN的燃烧行为有很大的影响，将持续燃烧的压力极限显著地扩展到真空区。在1-10 Mpa的压力范围内，线束横截面尺寸的减小导致ADN燃速的降低，并伴随着燃速数据的显著分散。实验结果表明，ADN燃烧过程中的主要原因是放热凝聚相分解反应起主导作用。提出了一种描述机理，解释了添加少量不同物质对ADN燃烧行为和自持燃烧低压极限的影响。
The paper presents a detailed analysis of the ammonium dinitramide (ADN) combustion behavior depending on organic and inorganic additives, material of the surrounding shell, and the sample cross-section size. In spite of the fact that ADN is an oxidizer, combustible surroundings have been found to exert practically no effect on the burning rate of ADN pressed strands. In contrast, minor amounts of organic and inorganic admixtures were shown to have a strong effect on ADN burning behavior, extending considerably the pressure limit of sustained combustion to the vacuum area. Within the pressure range of 1-10 MPa, a decrease in the strand cross-section size leads to a decrease in the ADN burning rate, accompanied by a notable burning-rate data scatter. The main reason for the observed combustion behavior is assumed to be a dominant role of exothermic condensed-phase decomposition reactions in burning of ADN. A descriptive mechanism has been proposed to explain the influence of small amounts of different substances added to ADN on its combustion behavior and the low-pressure limit of self-sustained burning.
