A fire extinguishing device comprising liquid nitrogen filled canister-tank attached to a device to release the LN contents; wherein, the release mechanism comprises a small explosive to tear open the canister and rapidly disperse the LN. The bombs are opened at desired locations and are delivered by any means comprising the aerial, vehicle, drone, robotic systems and hand operated by firemen. The device is used for the purpose of extinguishing forest fires or structure fires.

When it comes to extinguishing destructive fires, one of the greatest tragedies of property loss in fires is the damage done by the water during the extinguishing process. It can be extreme. This invention eliminates the water and the resulting damage and greatly reduces the cost of cleanup and repair after the fire is extinguished.

Furthermore, the greatest threat to fire emergency personnel is close proximity to the fire. Often times, in order to put out a fire, such as in a building, a firefighter must enter the building to get access to the fire. This entails great danger and sometimes death or injury. This invention makes it easier and faster for firefighters to apply fire-extinguishing agents to the fire without entering the building.

Current technology does not offer these benefits.

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.

In aspects of a fire suppression apparatus, an elongated housing contains one or more fire extinguishing agents, and an explosive charge within the elongated housing. A trigger fuse ignites reactive to flame exposure, and the trigger fuse activates the explosive charge to expel the one or more fire extinguishing agents. Multiple fire suppression apparatuses can be linked for deployment in the path of a fire.

Firefighting gas releasing apparatuses may include a trigger housing. A containment shell having a plurality of interfaceable shell sections may be carried by the trigger housing. The shell sections may be positional in a closed shell configuration and an open shell configuration. A shell interior may be formed by the shell sections in the closed shell configuration of the containment shell. The shell interior may be configured to contain a supply of at least one fire-suppressing gas. A plurality of shell retention members may removably engage the shell sections. A shell retention strap may releasably engage the shell retention members. The shell retention strap and the shell retention members may retain the shell sections in the closed shell configuration of the containment shell. A retainer piston may be disposed in the trigger housing. The retainer piston may be selectively positional in a strap-retaining configuration engaging the shell retention strap and a strap-releasing configuration disengaging the shell retention strap. The retainer piston may be configured to engage the shell retention strap and maintain the shell sections of the containment shell in the closed shell configuration and disengage the shell retention strap for release of the shell retention strap from the shell retention members, disengagement of the shell retention members from the shell sections and disengagement of the shell sections from each other in deployment of the containment shell to the open shell configuration.

The present disclosure provides generally for a system and method for planting flora, fauna, and dispersing various organisms through drone delivery. The system may comprise of a drone with seedling box that may hold and drop the pods containing flora or fauna. The seedling box may hold the pods with the flora or fauna in them and at specific intervals drop the pod with the flora or fauna. The seedling box may also hold various organisms or other materials and drop these organisms or materials when directed. A seedling box may comprise loading mechanism and deploying mechanism to facilitate accurate, timely deployment of the pods containing the seedlings. A pod may comprise a weighted tip with hollow cavity for seedling placement and a vertical rod for securing seedling during deployment. Where the system comprises uneven number of seedlings, seedling box may include counterweights to provide stability in configured flight patterns for duration of seedling deployment.

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.

An unmanned aerial vehicle (UAV) can be configured for fire suppression and ignition. In some examples, the UAV includes an aerial propulsion system, an ignition system, and a control system. The ignition system includes a container of delayed-ignition balls and a dropper configured, by virtue of one or more motors, to actuate and drop the delayed-ignition balls. The control system is configured to cause the UAV to fly to a site of a prescribed burn and, while flying over the site of the prescribed burn, actuate one or more of the delayed-ignition balls. After actuating the one or more delayed-ignition balls, the UAV drops the actuated one or more delayed-ignition balls from the UAV onto the site of the prescribed burn.

A high-altitude jettisoning aiming method and system applied to an unmanned aerial vehicle and a storage medium, the method includes collecting a current inclination angle and height information of the unmanned aerial vehicle when the unmanned aerial vehicle is hovering at a fixed point over a target position; calculating a current wind speed and wind direction according to the inclination angle; estimating an offset between an actual jettisoning position of a jettisoned object and the target position according to the wind speed, the wind direction and the height, the offset including an offset orientation and an offset distance; and controlling, according to the offset, the unmanned aerial vehicle to adjust the hovering position such that the actual jettisoning position of the carried object overlaps the target position after the adjustment.
