A kind of ultrasonic system is designed for generating high-power ultrasonic wave. The powder combustion or explosive detonation is used to produce high-pressure and high-velocity gas flow, which drives the Hartmann ultrasonic generator to produce high-power ultrasonic wave. The ultrasonic generation system uses sound waveguide to focus the ultrasonic wave to a certain direction for effectively increasing the action range. Only a single ultrasonic system can produce the megawatt power of 20 kHz ultrasound and the effective action range is up to 54m. The high-power ultrasonic system designed can completely meet the operational need.
