According to some examples of the presently disclosed subject matter there is provided a system and method for deploying a plurality of unmanned aerial vehicles (UAVs) by an airborne carrier aircraft for dispersing payload material, each UAV comprising at least one container containing payload material and being configured to disperse the payload material at a designated dispersion area in an event site.

Wildfires release enormous quantities of carbon dioxide and other greenhouse gases in addition to devastating animal habitats, destroying homes, and causing fatalities. Drones equipped with artificial intelligence to navigate through wooded locations, fire-detection hardware, and firefighting hardware can protect the environment by preventing wildfires. Methods can use a drone system that includes one or more drones to prevent wildfires. Each drone can include an infrared camera configured to detect fires. Each drone can fly in view of areas that might have a fire. After detecting a fire, the drone system can put out the fire if the fire is small. The drone system can also notify systems and people who can put out the fire.

Wildfires can quickly grow to enormous scales with devastating environmental impacts. Drone systems that provide early detection of wildfire risks can prevent wildfires before they grow out of control. Methods can use drones equipped with artificial intelligence to navigate through wooded locations and detect fire risks. Drones can include fire-detection hardware and fire-fighting hardware.

A control device of a fluid storing and jettisoning system with which a host aircraft is equipped, comprising a fluid reservoir and at least one tube, is connected to valves for allowing or preventing the jettisoning of water and controls the flow rate of fluid jettisoned and the jettisoning duration depending on at least one parametrized criterion.

A fluid storing and jettisoning systems with which host aircraft for fighting fires are to be equipped and which makes it possible to limit the dispersion of water in the air. The aircraft fluid storing and jettisoning system comprises a fluid reservoir and at least one tube comprising a closed tank having at least one opening intended to be connected in leak-tight fashion respectively to said one or more tubes for the entry of fluid and at least one opening oriented so as to make it possible to jettison the fluid in a determined direction that is different from the longitudinal direction of flow of the fluid in the one or more tubes. Also an aircraft equipped with such a system.

Environmentally-clean fire inhibiting and extinguishing dry powder compositions and products for sorbing flammable liquids while inhibiting ignition and extinguishing fire involving flammable hydrocarbon liquids such as, oils, fuels and non-polar solvents such as ketones and alcohols. The dry powder chemical compositions are made by mixing, blending and milling to suitable powder particle sizes, the following components: a fire extinguishing agent in the form of at least one alkali metal salt of a nonpolymeric saturated carboxylic acid; a powder fluidizing agent to help provide the dry powder composition with excellent fluid flow characteristics; and an oleophilic/hydrophobic composition for absorbing liquid hydrocarbons, while repelling water. A surfactant may be added to promote the formation of anhydrous semi-crystalline metal mineral salt film onto the surface of flammable hydrocarbon liquids involved in fire outbreaks to be extinguished and preferably absorbed by the dry powder chemical compositions.

A flame retardant product that contains an aqueous solution that includes a hydroxylated carbon-based component, an intumescent agent suitable for at least partially or even completely dehydrating the hydroxylated carbon-based component in such a way as to generate, under the effect of heat, a carbonaceous foam, and a thixotropic agent, selected to have a viscosity that increases as a result of water being added in the absence of shear. The solution has a sufficient concentration of the hydroxylated carbon-based component and the intumescent agent so that an addition of water to said solution increases the viscosity thereof in the absence of shear. The content by weight of the hydroxylated carbon-based component is greater than 10%.

An aircraft usable as a passenger aircraft and a fire fighter aircraft. The passenger aircraft includes a passenger area with passenger seats and a permanently installed fire extinguishing medium tank for storing fire extinguishing medium such as water, as well as a fire extinguishing medium nozzle for discharging the fire extinguishing medium. The passenger aircraft may be a type from an aircraft series also including a long-haul aircraft having a center tank for range extension. In the passenger aircraft, a center tank may be used as an extinguishing medium tank.

An accessory for an unmanned aerial vehicle (UAV) comprising a baseplate that is attached to the UAV unmanned aerial vehicle, at least one dispersant canister that is removably attached to the baseplate, a radio frequency receiver, an auxiliary circuit board, at least one battery, first and second wire pairs that supply electrical current from the auxiliary circuit board, a protective housing, and a radio frequency transmitter that is in communication with the radio frequency receiver. In alternate embodiments, the invention further comprises an electric match, linear solenoid, or electric primer.

A fire suppression apparatus for fighting fires from a vehicle configured for flight is disclosed, comprising a foam and water held in separate containers aboard the vehicle that when mixed forms a fire retardant, a pump driven by an electric motor to pressurize the fire retardant, the pump including an air induction valve where air is drawn into a suction end of the pump and pressurized together with the fire retardant, and an aimable boom connected to the pump by a conduit, the boom including a nozzle on a distal end of the boom from which the pressurized fire retardant and air is dispensed toward a target.
