Popis: There has been development, deployment and exploitation of various systems to trigger snow avalanche artificially and minimize the chance of occurrence of snow avalanche in an unpredicted manner. Few of these are based on the usage of explosives to generate adequate blast Peak Over Pressure (POP) above the fracture zone in the pre-surveyed and identified avalanche prone areas. In an ongoing study on development of a special class of high explosive ammunition for being fired with 84mm Recoilless Weapon System, the need to evaluate the quantum of blast POP has been understood. In the presented study, the tentative configuration of the projectile, the nature and quantity of explosive and the resulting terminal performance have been discussed. Numerical simulations and well-established formulations have been used to predict the levels of blast POP generation due to the ammunition and the outcomes have been compared. The work has been extended to validation of the generated outcomes with the data obtained by conducting static experimentation with the high explosive filled prototypes and measuring the blast POP at mean sea level as well as at high altitude.
