摘要
将对称与非对称平板在滑移爆轰驱动下的运动与 Laval喷管扩张段进行对比 ,利用Laval喷管的一维理论 ,推导出了对称与非对称平板在炸药爆轰驱动下的二维抛掷公式。对于气体多方指数 γ≠ 3的情况 ,采用小参数摄动法进行了求解。理论与计算结果表明 ,在小抛掷角范围内 。
The motion of symmetrical or symmetrical plates driven by sliding detonation was compared with the exhaust part of the L aval nozzle. Based on the one dimensiona l theory of the Laval nozzle,the two dim ensional motion formulas of flying plate s under sliding detonation were deduced out.For γ≠3 explosives,the little parameter disturbed meth od was induced to solute the problem. As a result, the calculation proved that t heoretical solutions were very precise i n the range of little bending angle.
