A method of fire-fighting is provided based on unmanned aerial vehicles “UAV(s)” launched from transporter aircrafts to deliver water or fire-retardants or any other fire-fighting materials to a location selected by the fire-fighting personnel. A capability of putting-off high intensity forest fires is provided that stems from the precision and the quantity of material that can be delivered per unit surface per unit time. After releasing the fire-fighting material(s), the UAV reaches a safe altitude from which it flies on autopilot to intercept and then proceed on a pre-programmed route to land per pre-programmed instructions on an airfield from which fire-fighting transporter(s) operate, allowing a high efficiency along the line, from loading the transporter airplanes to maximizing the quantity of material that reach the target, to minimizing the remote-pilot time and up to the recovery system that minimizes the recovery cost and it maximizes UAVs' utilization by a quick turnaround.

It is designed to be thrown a distance so that it can reach areas of difficult access and project the extinguishing agent achieving a fast extinguishing, it consists of a body (1) of spherical configuration in turn comprising a lower tank (4) which has a partially spherical configuration housing the extinguishing agent, which is formed by a first half-body (5) and a second half-body (5′) joined together, and an upper spray cap (7) equipped with spray nozzles (8) which are joined to the lower tank (4), and a solenoid valve (3) automatically or manually activated by remote control which allows the passage of the circulation of the extinguishing agent from the tank (4) to the spray nozzles (8) for its mass propagation from said spray nozzles (8) towards the exterior to extinguish the flames.

Apparatus and method for firefighting includes a containerless core of a fire retardant material, compressed to form a prolate spheroid shape. A shaft with fins and a carrying hook can extend from the core tail. The core can have a core charge of an explosive material within the core channel. An altimeter sensor coupled to the core charge and a triggering mechanism is coupled between the altimeter sensor and the core charge, and causes the triggering mechanism to detonate the core charge when the apparatus reaches an altitude. A delivery apparatus is included with a frame having carry harness, and at least one holding hook on the frame coupled to the carrying hook. The carry harness supports delivery apparatus in transport. Powders of calcium carbonate, magnesium carbonate, ammonium sulfate, diammonium sulfate, diammonium phosphate, ammonium polyphosphate, or monoammonium phosphate can be intermixed as fire retardant, along with indigenous plant seed.

A fire suppression device may be launched from a hand-held, stand alone, or object- or vehicle-mounted device. The fire suppression device may be propelled by a first accelerant ejected out of a proximal end of the fire suppression device. The fire suppression device may be ruptured by a second accelerant after a predetermined amount of time. A fire suppressant may be dispersed on a fire when the fire suppression device is ruptured.

A liquid projection bomb includes a shell and is characterized in that functional liquid is filled into the shell, and the shell is made of a soft or hard material easy to crack when bumped. The functional liquid includes water, alcohol, fuel oil, and a solution of water mixed with an extinguishing agent, a fertilizer or a drug.

A method and apparatus for delivering fire retardant to a ground fire from an aircraft. The apparatus includes a dispenser casing that dispenses fire retardant after the casing has been released from an aircraft. The apparatus includes a dispenser fuse that actuates the dispenser casing to dispense the fire retardant in response to one or more predetermined conditions.

The invention discloses a unidirectional spray type fire extinguishing bomb without high explosive fragmentation, includes a housing, a fuse, an igniter, an fire extinguishing agent and a main charge, and further includes a tail braking device, combustor, a plate closure, a piston and a diffuser. The housing, the tail braking device and the piston are made of light metal materials; the housing is cylindrical; the tail braking device is arranged at the bottom of the housing and is fixed with the housing through a screw nail; and the fuse is arranged on the diffuser and is fixed through a screw nail. During working process, when the fuse detects the fire extinguishing bomb to be 5-10 meters far away from a combustion source, the igniter ignites the main charge, the piston is pushed under high pressure to move in the housing, and the fire extinguishing agent is sprayed out from spraying holes to the combustion source for fire extinguishing. The present invention has simple structure, and has no lethality when the fire extinguishing agent is sprayed.

A system includes a plurality of inflation balls configured to be launched and a connection mechanism. The plurality of inflation balls are configured to modularly inflate with respect to one another to create a combined modular volume. The connection mechanism is configured to allow the modular inflation of the plurality of inflation balls with respect to one another.

The present disclosure provides a throwing device with a launcher and a propulsion system. The propulsion system comprises a retardant set between two sections of propellant for delaying the combustion and reducing the generated smoke or heat while launching the propulsion system. The launcher comprises: a tube for containing the propulsion system; and a trigger for triggering the ignition cartridge. A screw hole is in center of a bottom of the first chamber; nozzles are located around the screw hole; and a collar with a hole fixed in the bottom of the first chamber, wherein the ignition cartridge is fixed in the screw hole by the collar. The ignition cartridge comprises an explosive primer, and the launcher further comprises a firing pin triggered by the trigger to hit the explosive primer.
