US Patent 10054388 Methods and apparatus for disarming an explosive device

A disrupter cannon is used to disrupt or destroy explosive devices. A disrupter cannon may launch a liquid (e.g., water) toward an explosive device to disrupt the explosive device. The liquid may be launched through a nozzle. The nozzle may include passages that spread the liquid to for a column of liquid with a cross-section. A nozzle that provides a column of liquid with an oval cross-section may be more effective at disrupting certain types of explosive devices.
