摘要： A system for mixing fire-suppressant gel with water on board an aircraft includes a gel reservoir mounted in the aircraft, a pump for injecting gel into a flow of water into an aircraft-mounted payload tank, and a control system for controlling gel-water mix ratios. The control system monitors water volume flowing into the water tank, and regulates the gel pump to inject gel in appropriate amounts to produce gel-water emulsions having precise gel-water ratios. Settings for the control system are set by the pilot before water flow water is initiated. Once the aircraft is in flight, the gel-water mixing process is automatically controlled through a trigger on the pilot's control stick. The aircraft may be a helicopter or fixed-wing aircraft adapted to load water from a lake or other source while in flight, or a fixed-wing aircraft adapted to load water on land from a pressurized water source.

摘要： A tank on a firefighting aircraft initially is loaded with water. A polymer gel emulsion vessel is provided on the aircraft, but is not activated and mixed with tank water until such polymer gel preparation is initiated by an operator. When initiated, a pump pulls water from the tank and doses it with gel emulsion. 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 mixing paddles or sparging with gas. In one embodiment, a hollow tower of telescoping form has a float to keep an upper end near a surface in the tank and a sparging gas entry is a controlled distance below the surface, such that gas of limited pressure, such as from a ram air inlet can sparge and mix the water and activated polymer gel emulsion effectively.

摘要： The system includes an intake assembly upstream of a pump within the bucket which selectively uses an outer port for drawing water outside of the bucket into the system and an inner port for drawing water from within the bucket into the system. A polymer gel port is interposed between the intake assembly and the pump for combination, mixing and activation of a water and polymer gel emulsion combination within the pump. A fill assembly is provided downstream of the pump which can selectively direct water back into the bucket. A discharge assembly is also provided downstream of the pump which leads to a nozzle or other outlet for water and/or polymer gel emulsion from the system. A control valve selects between delivery of water and/or polymer gel emulsion back into the bucket through the fill assembly or out of the bucket through the discharge.

摘要： The system includes a pod suspended beneath the aircraft and above a water fillable and emptyable bucket. Polymer gel emulsion preparation equipment is included at the bucket. The pod includes an elongate shaft for carrying structural loads between a cable extending down from the aircraft and the bucket. The pod also includes a polymer gel tank. A polymer gel pump delivers polymer gel to the polymer gel emulsion preparation equipment within the bucket when required. The pod is configured to include a pathway for routing of various lines from the aircraft down to the bucket, and past the polymer gel tank. Sub-systems for filling the polymer gel tank and for equalizing pressure within the polymer gel tank are also included with the pod, so that the pod provides a modular polymer gel storage for use with polymer gel emulsion preparation equipment within a bucket suspended beneath the aircraft.

摘要： A method for mixing fire fighting gel in situ within a water tank of a fire fighting aircraft. A first step involves mounting a chemical tank to a fire fighting aircraft having a water tank. A second step involves injecting gel forming chemical from the chemical tank into a turbulent flow of water entering the water tank of the aircraft to achieve a required ratio of gel forming chemical and water, with the turbulent flow of water serving to mix the gel forming chemical with the water.

摘要： A system that allows a gel to be formed by mixing the solid precursor of the gel and water and spraying same onto surfaces is provided. The system includes: a conveyor for the added gelling agent or solid; a pair of openings on the sides of the conveyor tube; a dosing device located after the openings, which distributes the amount of solid added to the conveyor; a Venturi shut-off valve; a mains connection which allows water to enter the system when the water shut-off valve is opened; a Venturi inlet pipe which connects to the Venturi chamber through which the water passes; a Venturi outlet pipe through which the water passes with the solid; and a lance for discharging the gel produced by mixing the water and the solid.
