Study on Shock Wave Characteristics of Different Charges by Underwater Explosion

Characteristic parameters, such as impact wave pressure, time reduces constant, etc, of complex-PBX, fusing THL, thermoplastic THL and TNT are analyzed utilizing tested data in underwater explosion. Underwater explosion power of different charges is compared. The result indicates that the peak pressure of four charges are, from high to low, thermoplastic THL, fusing THL, TNT, complex-PBX; Decay constant are, from high to low, complex-PBX, thermoplastic THL, fusing THL, TNT; Contrast shock wave pressure impulse are, from high to low, complex-PBX, fusing THL, thermoplastic THL, TNT. Therefore, complex-PBX is the best performance of charges by multi-parameter comprehensive evaluation.
