Abstract: A first drone equipped with a high energy Directional Ultrasound Parametric Speaker Array and a second drone equipped with an Acoustic Dispersion Cannon are used to fight wildfire. The first drone is distanced far from a burning flame but in close proximity to a fire target. Both drones are guided by GPS to communicate with remote operators. Once the target is locked, the first drone blasts the target with Amplitude Modulated Ultrasound. The Ultrasound is self-demodulated into a lower frequency audio sound when it encounters a hot flame of richly charged ions. The lowered frequency sound pushes and pulls the flame forward and backward rapidly away from the combustion source, causing it to be disconnected from the flame which instantly cools down and is extinguished. The second drone blasts the combustible source with powerful sonic shockwaves to disperse the still hot particulates further apart to prevent the source being reignited.
