Abstract

Based on the known (rated) values of the densities and temperatures at the beginning and end of the decomposition of thermal-protective binder composite materials, as well as on the exponential nature of the decomposition (pyrolysis) of the binder composite materials, the law of binder pyrolysis is established with the formation of a gas component and a porous coke residue, through which the pyrolysis gases are filtered and are blown into the high-temperature boundary layer. The law is universal in nature and suitable for almost any heat-shielding composite materials, since it does not use the chemical kinetics of decomposition, which are difficult to formalize. The use of this decomposition law will greatly simplify the mathematical modeling of complex processes for the design of thermal protection for high-speed and hypersonic aircraft. An analysis of the obtained calculation results is presented.

热保护粘结剂复合材料高温分解的普遍规律

摘要

根据热保护性粘结剂复合材料分解开始和结束时的密度和温度的已知（额定）值，以及粘结剂复合材料分解（热解）的指数性质，定律通过形成气体成分和多孔焦炭残留物来建立粘合剂热解机理，将热解气体过滤并吹入高温边界层。该定律本质上是普遍适用的，几乎适用于所有隔热复合材料，因为它不使用难以形式化的分解化学动力学。使用该分解定律将大大简化用于高速和超音速飞机的热保护设计的复杂过程的数学建模。
