Abstract


Various experiments were performed on water disruptor to measure the velocity of water and projectile. In these experiments, double base propellants having different physical and chemical properties were utilized to drive the projectile. This projectile was made up of nylon material. Measurement of projectile velocity is significant parameter for disruptor in neutralizing IEDs. An attempt has been made to develop a mathematical model for processes taking place inside the water jet disruptor using internal ballistics model. A code has been developed based on the mathematical model and simulated for various input parameters. The validation of the code has been done by comparing the results with experimental firing. A parametric analysis is carried by varying barrel length of the disruptor, propellant type and projectile mass.
