When extinguishing high-altitude forest fires from the air, two problems are consistently encountered:

1. When extinguishing from aircraft at a safe altitude for the equipment and personnel, over 90% of the extinguishing water evaporates, losing the majority of its extinguishing effectiveness.
2. The limited amount of water reaching the ground mostly fails to hit the advancing fire front because capturing it from a linear trajectory and high-speed-moving aircraft is extremely challenging.

REVOLUTIONARY SUPPRESSION TECHNOLOGY

• Fast: Extinguishing from the air reaches the suppression area most quickly. The extent of damages depends on the speed and efficiency of the initiation of suppression operations.
• Precise: Extinguishing from UAVs or drones enables the most precise targeting of the fire front. For extinguishing larger areas, a drone swarm can be utilized, composed of four drones with a payload capacity of 300 kg each.
• Efficient: The new suppression technology allows the transformation of extinguishing water into microdroplets, achieving uniform coverage of the suppression area and the maximum possible extinguishing effect.

AERIAL SUPPRESSION WITH A CLOUD OF MICRODROPLETS

Using an extinguishing container containing 200 liters of water, approximately 400-600m2 of burning surface can be extinguished. The UAV/drone drops the container above the fire, and at a pre-set height, the container detonates with a small and highly controlled explosion, turning the water inside into a cloud of microdroplets.

RAPID SPEED OF THE MICRODROPLET CLOUD

The controlled explosion transforms extinguishing water into microdroplets while giving the resulting cloud of microdroplets high speed. This facilitates the spread and expansion of the cloud over a long distance, allowing the extinguishing of 1 liter of water to cover 2-3 m2 of burning surface.

The high speed of microdroplets enables the extinguishing water to penetrate the structure of a burning tree and prevent or reduce re-ignition.
