| 摘 要： | 研究了再入体零迎角再入飞行过程中的烧／侵蚀耦合效应，讨论了烧／侵蚀耦合效应对导弹落点的影响，在研究过程中提出了烧／侵蚀外形法向处理方法，并对不同的再入条件进行了烧／侵蚀外形及再入弹道计算，计算结果表明，烧／侵蚀外形法向处理方法简单可靠；零迎角再入飞行时烧／侵蚀耦合效应能够引起一定的落点偏差，且落点偏差的值与再入条件有关。

| Abstract: | This thesis studies the coupled ablation/ erosion effect of reentry-body during reentry process at zero-lift and discussed the influence on the impact-point. The normal direction ablation/erosion shape-change equations are established in this paper and it has been proved reasonable and acceptable. Several cases with various reenty conditions have been studied to discuss the influence of the coupled ablation/erosion effect on reentry-body impact-point. The results show that it can cause the missile impactpoint deviation to some degree, and the impact-point deviation number varied with the reentry condition. |
