Study on energy output characteristics calculation method of two charges´ shock wave from underwater explosion

Multi-charges exploded synchronously are very useful to improve explosion power. But, there is few of information concerning the peak pressure calculation of two charges´ shock wave in present research. The calculation method based on distribution of emitted energy proposed in this paper, considered that under the influence of first charge´s emitted energy, the second charge´s propagation is changed. Then the correctness of the method has been proved through a series of experiments. Finally, the second charge´s peak pressure and its change in entire plane are proposed. This method provides reference information for underwater explosion implement of multi-charges.
