A method for predictive fire control, comprising identifying a plurality of wildfire risk points on a power grid, calculating a route for an unmanned aerial vehicle (UAV) to intersect with a maximum number of points as a function of a range of the UAV, controlling the UAV to traverse the route, monitoring one or more sensors for an indication of a wildfire event and controlling the UAV to release a fire retardant on the fire.

A system for dispersing liquid over a desired location, the system comprising a pressurized tank having a main body, an inlet in fluid communication with the main body for introducing liquid to the main body, an outlet in fluid communication with the main body for dispersing the liquid, and an air inlet for charging air under pressure into the main body, where the improvement comprises providing a diffuser for slowing down pressurized air entering the main body from the inlet.

A tank on a firefighting aircraft initially is loaded with water. A polymer gel emulsion vessel is provided but gel emulsion is not activated and mixed with water in the tank until such polymer gel preparation is initiated by an operator. When initiated, a pump pulls water from the tank and returns water back to the tank with a dose of gel emulsion supplied therein. Double elbows and/or the pump impeller fully activates the polymer gel. The activated polymer gel is mixed within the tank by one of a variety of systems including sparging with air, routing of return water from the pump through nozzles and providing a baffle for generating circulatory mixing flow within the tank, or utilizing a mixer element which moves dynamically within the tank. Hydrodynamic forces associated with the aircraft passing over a body of water can power dosing of the water with polymer gel emulsion.

The instant invention relates to an apparatus and method for enhancing the fire extinguishing properties of water for use with fire fighting aircraft. The apparatus and method includes the steps of, and equipment for, transferring media into a holding tank in aircraft; filling a reservoir hopper with water in the aircraft; calculating the amount of media to be added to the reservoir; drawing the calculated amount of media into the reservoir to form an enhanced fire fighting admixture while the aircraft is in flight, wherein the admixture is offloaded by a controlled discharge for use in fighting forest fires.

Damage mitigating apparatus comprises in one embodiment a damage mitigating aerial vehicle that has sensors for detecting flight related characteristics and a communication unit for commanding activation of parachute deploying apparatus and of a lift generator deactivation unit following determination of a flight failure. In one embodiment, an aerial vehicle transmits a critical failure alarm signal to an unmanned aircraft traffic management system (UTM) following detection of the failure, and the UTM transmits a warning signal to neighboring aerial vehicles that are predicted to be in a vicinity of the descent path of the failed aerial vehicle to avoid collision with the failed aerial vehicle. The damage mitigating apparatus facilitates performance of a damage mitigating operation.

An expandable probe for filling a water tank in an aircraft from a body of water includes an inflatable hose having a proximal end fixed with a housing in the aircraft, a distal end fixed with a scooping head, an elastomeric internal conduit, and an inflatable bladder substantially surrounding the conduit. The conduit has a proximal end in communication with the water tank of the aircraft and a distal end fixed with a water scoop of the scooping head. An air supply is adapted to inflate and extend the inflatable hose to an extended configuration extending outside an open rear end of the housing below the lower side of the aircraft. Lowering the aircraft allows the scooping head to contact the body of water such that water enters the scoop and travels up the conduit to the water tank.

The present apparatus, method, and system utilize sound waves to suppress fires using metasurface lenses that can work in concert with detectors to amplify and optimize sound pressure level and thereby deprive a fire of needed oxygen. Metamaterial is utilized that manipulates the propagation of acoustic waves by its structural makeup rather than its interior chemical makeup, thereby adjusting the phasing of sound waves to form converging beams of constructive interference even after the waves exit the material, ultimately making long-range fire-extinguishing accomplishable.

The invention relates to a method for fighting and/or extinguishing a forest fire, comprising the following method steps: performing a first detection of a seat of the fire using a first forest fire detection sensor; performing a first localisation of the seat of the fire; positioning a second forest fire detection sensor; performing a second detection of a seat of the fire; performing a second localisation of the seat of the fire; fighting and/or extinguishing the seat of the fire by means of a forest fire fighting unit. The invention also relates to: a forest fire fighting system comprising a first forest fire detection sensor for detecting forest fires, a position determining system which is suitable and provided for determining the position of the first forest fire detection sensor, and a second forest fire detection sensor; a locating system which is suitable and provided for determining the position of a seat of the fire; and a forest fire fighting unit.

The invention relates to a method for suppressing and/or extinguishing a wildfire using a wildfire extinguishing station, having the steps of receiving information, generating a control command, transmitting the control command or information, and carrying out the wildfire suppression process. The invention additionally relates to a wildfire suppression system comprising a network device, a server unit, a gateway, a first terminal, said first terminal having a sensor unit, and a second terminal, said second terminal having a wildfire suppression element.

A system for forming and maintaining GPS tracked and mapped environmentally-clean chemical-based fire protection zones formed over property and ground surfaces in and about a neighborhood of homes, that proactively inhibit fire ignition and flame spread when exposed to wild fire. The system includes a GPS-tracking anti-fire (AF) liquid spraying system wirelessly connected to a wireless communication network supporting a network database. The GPS-tracked anti-fire liquid spraying system is used to spray particular GPS-specified ground surfaces in and about the neighborhood, with an environmentally-clean anti-fire chemical liquid so to form environmentally-clean chemical fire protection zones over the GPS-specified property surfaces, while generating GPS-coordinate and time/date stamped data records pertaining to the application of the environmentally-clean anti-fire chemical liquid spray during the formation of the environmentally-clean chemical fire protection zones. The GPS-coordinate and time/date stamped data records are transmitted over the wireless communication network for storage in the network database. A mobile computing system is used to access the GPS-coordinate and time/date stamped data records from the network database, relating to the formation of the GPS-specified environmentally-clean chemical fire protection zones, so as to verify that the GPS-specified environmentally-clean chemical fire protection zones were formed at the GPS-specified property surfaces on the particular date, to proactively inhibit fire ignition and flame spread when exposed to wild fire.
