An embodiment of a fire suppression apparatus for fighting fires from an aerial vehicle is disclosed having a foam and water held in separate containers that when mixed forms a fire retardant in the separate water container, a pump driven by a first electric motor, the pump including an air induction valve positioned at the pump inlet where air and the fire retardant are drawn into the inlet and pressurized simultaneously by the pump, a primer pump driven by a second electric motor to prime the inlet with the fire retardant before starting the pump, an inverter to control startup of the first electric motor, 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 water/foam/air fire retardant is dispensed toward a target. Vertical mount plates can attach the apparatus to opposite sides of the helicopter.

The present invention relates to a multipurpose water/fire suppressant sprinkler system designed to be attached to an aerial vehicle such as a helicopter or firefighter plane. The multipurpose sprinkler system features a plurality of concentric tubes or, alternatively, a single spiral tube. The plurality of concentric tubes or single spiral tube each further comprise a plurality of sprinkler heads in fluid communication with a material holding tank, wherein water or a fire suppressant material in the material holding tank is selectively discharged from the tank through the plurality of sprinkler heads. The flow of water or the fire suppressant material can be controlled through a valve connected to the system.

Dry powder chemical compositions for extinguishing fires 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 a surfactant that promotes the formation of anhydrous semi-crystalline metal mineral salt film onto the surface of flammable hydrocarbon liquids, involved in the fire outbreaks to be extinguished and preferably absorbed by the dry powder chemical compositions.

A fire suppression system has a unique combination of components that includes interoperable electric-powered vehicles, facilities, hardware and software along with their range of specifications, standards, processes, capabilities and concepts of operations that comprise a concerted, multi-modal, system for delivering fire-retardant onto fires by uniquely-capable, ultra-quiet, electrically-powered, autonomous robotic aircraft (“SkyQarts”) that fly precise trajectories and perform extremely short take-offs and landings (ESTOL) at a highly-distributed network of small facilities (“SkyNests”) that have standardized compatible facilities, as defined herein, that interoperate with SkyQarts as well as with versatile, autonomous robotic electric-powered payload carts and electric-powered autonomous robotic delivery carts to provide safe, fast, on-demand, community-acceptable, environmentally friendly, high-capacity, sustained, affordable, day or night delivery of fire-retardant, even in smokey, IFR conditions to wildfires or controlled burns in urban, suburban, wildlands and rural settings in both developed and undeveloped countries across the globe.

Environmentally-clean aqueous-based fire inhibitor biochemical compositions in liquid phase that can be atomized and sprayed, over a broad ambient working temperature range, as a fine mist over ground surfaces, native ground fuel, living plants, trees and shrubs and when dried forming a durable fire protective coatings having improved surface coverage, and being an effective proactive wildfire inhibitor. These environmentally-clean aqueous-based fire inhibitor biochemical compositions can also be applied to wood products, and wood-framed and mass-timber buildings, decks and anything of a combustible nature, to provide proactive wildfire protection without compromising wood-fiber strength or producing volatile organic components (VOCs).

An airborne fire suppression system comprising a flying device, a deployment apparatus and folded fire suppressing blanket configured to allow quick and smooth deployment on or as a barrier to a forest fire or a building or other object on fire.

A process of forming strategic chemical-type wildfire breaks on ground surfaces to proactively prevent fire ignition and flame spread, and reduce the production of smoke in the presence of a wildfire. The process involves using a wireless mobile information network for managing the application of a clean fire and smoke inhibiting slurry composition containing clean fire inhibiting chemicals, and cellulose or wood fiber, mixed with water and other additives, on ground surfaces in advance of wild fire, to blanket the ground surfaces from wildfire ignition, and also application over smoldering ambers and ashes to prevent re-ignition while reducing (i) the use of significant amounts of water, (ii) the production of toxic run off water, and (iii) toxic smoke.

An embodiment of a fire suppression apparatus for fighting fires from an aerial vehicle is disclosed having a foam and water held in separate containers that when mixed forms a fire retardant in the separate water container, a pump driven by a first electric motor, the pump including an air induction valve positioned at the pump inlet where air and the fire retardant are drawn into the inlet and pressurized simultaneously by the pump, a primer pump driven by a second electric motor to prime the inlet with the fire retardant before starting the pump, an inverter to control startup of the first electric motor, 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 water/foam/air fire retardant is dispensed toward a target. Vertical mount plates can attach the apparatus to opposite sides of the helicopter.

The helicopter drizzle pipe allows for aerial wildfire suppression efforts in otherwise inaccessible areas. The pipe is balanced between the bottom legs of the helicopter as to prevent an imbalance or obstruction to the helicopter rotor blades. Along the bottom of the pipe are strategically placed holes to allow the liquid in the pipe to drizzle out at a constant speed over the whole length of the pipe, simulating rainfall. Due to the pipe's positioning, it is also very easy to remove from the helicopter for refilling or cleaning. Furthermore, the method by which the liquid drizzles from the pipe does not necessitate aircraft movement, thus functioning even when the helicopter hovers to thoroughly cover a specific area.

Aspects of the disclosed embodiments relate to an aerial firefighting system for a helicopter, the firefighting system including: an external reservoir for storing water, wherein the reservoir includes a water outlet; a supporting frame coupled to an outer surface of the reservoir; and a moveable robotic nozzle fluidly connected to the water outlet and mounted on the supporting frame or attached to a hose reel for distributing water on a fire; wherein the moveable nozzle is operable by a user from within the helicopter to control the direction that the water is distributed.
