本文用热传导理论和后向有限差分法分析鱼雷战斗部装药室隔热涂层设计方案。计算结果证明,选用适当导热系数的绝热材料涂层来提高战斗部炸药耐火场的安全性是可行的。隔热涂层结构简单,技术易解决,可用于各种战斗部装药室内。 In this paper, the heat transfer theory and the backward finite difference method were used to analyze the design of the thermal insulation coating for the torpedo warhead’s charge chamber. The calculation results show that it is feasible to use the thermal insulation coating with appropriate thermal conductivity to improve the fire resistance of the explosive in the warhead. Insulation coating structure is simple, easy to solve technology, can be used for a variety of warheads charge room.
