| 摘 要： | 利用可压缩流的等熵无旋定常平面流理论及特征线法，研究了滑移爆轰作用下， 炸药上方带覆盖物时的飞板运动。计算结果表明，覆盖物使飞板抛掷角增大，加速段 增长。同时提出爆轰产物向空气飞散时，计算飞板运动可以只采用Ｐ－Ｍ流动解作初 始参数的新方法。

| Abstract: | The flyer plate motion under the action of glancing detonation of explosive with a cover is investigated. The calculation results show that the bend angle of the flyer plate can be increased, and its accelaration section can be lengthened by the cover. At the mean time, the new method of the calculation of the flyer plate motion, which only uses the P-M flow solution as the initial parameters, is given as the explosive products flying towards air. |
