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.

Avionic display systems and methods are provided for generating avionic displays including aerial firefighting symbology, which enhance pilot situational awareness and decision during aerial firefighting operations. In an embodiment, the avionic display system includes an avionic display device, a thermal image sensor configured to detect thermal image data external to the aircraft, and a controller operably coupled to the avionic display device and to the thermal image sensor. During operation of the avionic display system, the controller compiles a fire map of a fire-affected area in proximity of the aircraft based, at least in part, on the thermal image data collected by the thermal image sensor. The controller further generates a first avionic display on the avionic display device including graphics representative of a field of view (FOV) of the thermal image sensor and portions of the fire map outside of the FOV of the thermal image sensor.

Mobile fire-fighting assembly suitable for movement with an aircraft, wherein the mobile fire-fighting assembly comprises a fire extinguisher unit and water supply unit detachably arranged to each other by means of a suitable connection assembly enabling movement of the fire extinguisher unit and water supply unit together as one unit and separately.

An aerial drone is provided with a central passage and a rotating frame. A payload moves within the central passage through the drone body into a deployed position. The payload engages with the rotating frame and can be rotated into a desired orientation below the drone.

The present invention provides a fire-stopping suspension comprising a top suspension device and a bottom suspension device. The top suspension device comprises a first transmission mechanism, a plurality of shafts having fire-retardant fabrics thereon, and a top suspension support frame, wherein the first transmission mechanism drives the shafts to roll out or roll back the fire-retardant fabrics. The bottom suspension device comprises a second transmission mechanism, a plurality of first cutter shafts, and a bottom suspension support frame, wherein the bottom suspension support frame is suspended at lower ends of the fire-retardant fabrics, and the second transmission mechanism drives the first cutter shafts so that objects under the bottom suspension device can be easily cut and chopped by the first cutter shafts. The present invention also provides a method of using said fire-stopping suspension apparatus to stop the spread of fire.

A concentric, double hull, damage tolerant airframe vehicle double clad with a lightweight, impact resistant ceramic matrix composite for heat shielding and flame resistance, and fitted with insulation, to provide thermal protection from 35 C. to 1,650 C. of the internal fuselage areas for an extended period of time within an extreme heat environment, that will serve as a semi or fully autonomous vehicle, manned or unmanned, preferably an unmanned aerial vehicle designed as the delivery means to suppress or extinguish flames by repeatedly discharging pressure waves against flames without having to exit the fire environment.

Provided is a dropping-type fire extinguishing body that, in fire extinguishing using a gel-like fire extinguishing agent, can allow the fire extinguishing agent to be smoothly conveyed and dropped. A dropping-type fire extinguishing body 1 to be dropped onto the fire site to extinguish the fire, wherein a gelling agent 3 is contained in a bag body 2 formed of a water-permeable material and water is permeated into the body and is mixed with the gelling agent to prepare a gel-like fire extinguishing agent, thereby filling the gel-like fire extinguishing agent into the inside of the bag body.

An artillery shell is fired out of a gun towards a fire. A trigger releases a fire-retarding material from the artillery shell to retard the fire.

A method for dispersing liquid over a desired location, the method comprising a pressurized tank having a main body, an inlet in fluid communication with the main body for introducing liquid to the main body, an outlet in fluid communication with the main body for dispersing the liquid, and an air inlet for charging air under pressure into the main body, where the improvement comprises providing a diffuser for slowing down pressurized air entering the main body from the inlet.

A system for filling a tank for a firefighting helicopter with water without ground personnel, comprising a pilot controlled valve assembly to selectively permit water to flow into the refill tank upon the receipt of a communication transmitted by a communication device within the helicopter. The pilot controlled valve assembly can include a supply valve configured to move between at least a closed state and an open state, a controller configured to control the supply valve, and a receiver configured to send a signal to a controller to cause the controller to at least open the supply valve upon receipt by the receiver of a communication meeting one or more predetermined criteria. The water tank can be filled from a water source, including a municipal water source, when the supply valve is open to provide a more efficient, semi-autonomous refill tank system greatly improves costly and time-consuming manually refill systems.
