用于混合推进应用的燃料的消退速率由从反应交叉点产生的热通量密度与冷凝相过程所需的能量之间的耦合产生。三种燃料被认为是聚乙烯，实验室规模研究的参考材料，羟基封端聚丁二烯，助推器应用的候选材料，和缩水甘油叠氮聚合物。尽管是燃料，但其具有自主燃烧速率。凝相过程是一个不可逆的热裂解过程，不受压力的直接影响。这一过程的特点提出了三种燃料。烧蚀过程，在这里或在实验室设备或小型发动机的文献中测量，可以相当准确地描述纯燃料的扩散火焰方法。GAP的烧蚀主要由其自身燃烧控制，可能还有一些交叉流扩散火焰的附加效应，因此具有高的回归率。
The regression rate of a fuel for hybrid propulsion applications results from the coupling between the heat flux density issuing from the reacting cross {Jow and the energy required by the condensed phase process. Three fuels are considered polyethylene, a reference material for laboratory scale investigation, hydroxyl terminated polybutadiene, a candidate material for booster applications, and glycidyl azide polymer. which although being a fuel has an autonomous burning rate. The condensed phase process is shown to be an irreversible thennal pyrolysis not directly affecred by pressure. The characteristics of this process are presented for the three fuels. The ablation process, measured here or in the literature on laboratory devices or small motors, can be described quite accurately by the diffusion flame approach for the pure fuels. The ablation of GAP is dominated by its self burning with probably some added effect of the cross flow difTusion flame, with, as a consequence, high regression rates.
