内绝热层的炭化厚度和设计厚度计算

Computatuin of Charred Thickness and Design Thickness of Internal Insulation

根据内绝热层在固体火箭发动机中的作用,对其提出了若干要求;根据内绝热层的烧蚀机理,推导出内绝热层炭优厚度计算公式;根据燃烧室壳体对热防护的要求,给出了确定内绝热层设计厚度的方法。

The requirements for the internal insulation arc presented based on its functions in a solid rocket motor. The formulas to compute the charred thickness are derived based on its ablation mechanism and the methods to determine its design thickness arc given based on thermal protection for the chamber case.
