为研究 TATB 基和 CL-20基 PBX 爆轰波的拐角性能，采用蘑菇（Mushroom）试验计算了含95％TATB 基（PBX-Ⅰ）、CL-20基（PBX-Ⅱ）及添加了铝粉的 CL-20基（PBX-Ⅲ）炸药药柱在起爆直径10 mm 和6 mm 条件下的出射角、熄爆角及延迟时间，讨论了3种 PBX 炸药的爆轰传播特征和拐角性能。结果表明，起爆直径为10 mm 时， PBX-Ⅰ的出射角和熄爆角（22．7°和31．9°）明显小于 PBX-Ⅱ的出射角和熄爆角（均为90°）；起爆直径为10 mm 和6 mm 时，PBX-Ⅱ和 PBX-Ⅲ的出射角和熄爆角均为90°，都能够传播为类似球形。对于 CL-20基 PBX，随着铝粉的加入和起爆直径的减小，其炸药半球均能够达到可靠传爆状态，具有较好的拐角性能。TATB 基 PBX 炸药药柱的出射角和熄爆角均显著减小，表明 TATB 基 PBX 炸药药柱的拐角性能较差。3种 PBX 炸药的拐角性能优劣顺序为：PBX-Ⅱ＞PBX-Ⅲ＞PBX-Ⅰ。

To study the corner performance of detonation waves for TATB-based and CL-20-based polymer bonded explosive(PBX),the breakout angles,failure angles and delay time of PBX-Ⅰcontaining 95%TATB ,PBX-Ⅱ containing 95%CL-20,and PBX-Ⅲ containing 81.5%CL-20 and 13.5%Al with initiating diameters of 10 mm and 6 mm were studied by Mushroom test.The detonation propagation characteristics and corner properties of three kinds of PBX explosive charge were discussed.Results show that,the first breakout angle and failure angle of PBX-Ⅰ(22.7°and 31.9°,respectively) were significantly smaller than those of PBX-Ⅱ (90°for both)with initiating diameter of 10 mm,the first breakout angles and failure angles of PBX-Ⅱ and PBX-Ⅲ were all 90°with initiating diameters of 10 mm and 6 mm,and the detonation waves of PBX-Ⅱand PBX-Ⅲ can develop to similar hemispherical shape.Thus,for CL-20-based PBXs,their hemispherical charge could transmit detonation wave reliably in spite of the addition of Al powders and the decrease of initiation diameter, which implies that CL-20-based explosives have excellent performance of corner turning.When CL-20 is all substituted by TATB ,both the first breakout angle and failure angle decrease significantly,which means that TATB-based explosives have poor performance of corner turning.The corner performance of detonation waves for the three kinds of explosive decreases in the order:PBX-Ⅱ>PBX-Ⅲ>PBX-Ⅰ.
