【摘要】 本文将圆管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,推导出了圆管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。计算结果表明,在小抛掷角范围内,该方法有很好的计算精度。更多还原

【Abstract】 The motion of circular pipe driven by sliding detonation was compared with the exhaust part of de Laval nozzle.Based on the one-dimensional theory of de Laval nozzle,the two-dimensional formula for the motion of circular pipe driven by sliding detonation was deduced out.For those explosives that the polytropic exponent γ is not equal to 3,the little-parameter-disturbed method was introduced to solute the problem.As a result,the calculation proved that theoretical solution has a higher precise in the range of little bending angle.更多还原
