Building a miniature experimental model for camouflage underwater explosions

Abstract

In general, explosion experiments on miniature models are research methods commonly used in explosion research. Although the method of experimental explosion research on miniature models in laboratory conditions is very meaningful for practical application but up to now, there have been no published papers on the method of calculating and designing parameters on the size of miniature models that satisfy the conditions of camouflage underwater explosions (UNDEX), so that similar explosive effect laws when carrying out UNDEX in rivers and seas can be drawn, whose factors converting research results from miniature models to reality are also obtained. For the above reason, the paper aims to analyze the theoretical basis of the similarity model of an explosion, proposing a method for calculating and verifying the parameters of miniature experimental models on underwater explosion effects, conducting experiments, and establishing experimental laws. The result is a miniature model for experimental research on underwater explosions that satisfies the conditions of blasting in infinite environments and satisfies the similarity principle of shock wave pressure in water environments with a model correction factor of 1.45 to 1.47 times when compared to the methods of Russia and the United States, respectively.
