| 摘 要： | 为实现导弹自力发射时同心发射筒前盖自动向一侧开启,讨论了4种燃气开盖方案:易碎盖方案、内外筒偏心盖方案、半导流锥方案和各向异性材料发射筒盖方案,并用数值方法模拟了各种方案的筒内复杂三维流场.计算结果表明4种方案均具有可行性.经试验验证,各向异性材料的发射筒盖方案能按预先期望的方向整体飞出.

| Abstract: | In order to open the cover of a concentric canister launcher (CCL) automatically with the jet during its launching, four schemes are put forward, viz.fracturable cover, eccentrically positioned interior and exterior launching tubes, jet guides of assymmetric construction, and covers made of heterogeneous materials. Modes of flow under each scheme are numerically simulated. Detailed data show that all the four schemes are feasible, yet the last named scheme keeps the opened cover intact and makes it fly along the expected direction. |
