An adding system for fire-extinguishing units is disclosed for producing a mixture of extinguishing agent and extinguishing agent additive (premix) by adding an extinguishing agent additive, e.g., a foaming agent, to an extinguishing agent, e.g., water, the adding system comprising a motor, which can be driven by the extinguishing agent stream, an adding pump, which can be driven by the motor, an adding line, and an extinguishing agent additive line. The invention increases the operational reliability of an adding system for fire-extinguishing units by the outer wall of the working chamber of the motor being in the form of a rotation motor, which can also have the shape of a logarithmic spiral. Furthermore, the wall of the drainage housing of the motor, which is in the form of a rotation motor, can have a through-slot for letting the extinguishing agent in and/or out. Moreover, the inlet of the adding pump can be arranged such that the extinguishing agent additive can flow into the adding pump substantially parallel to the movement direction of the pistons of the adding pump. Finally, the adding pump can have an integrated relief valve.

A computer identifies, based on sensor data from one or more sensors located in proximity to a fire site and on a corpus of firefighting knowledge, one or more firefighting goals. The computer generates, based on the one or more firefighting goals and the corpus of firefighting knowledge, one or more firefighting recommendations. The computer scores, using the corpus of firefighting knowledge, the one or more firefighting recommendations based on historical effectiveness of prior firefighting actions.

Provided is a fire-fighting system that has a very simple structure with only a hose and a water discharge nozzle mounted on a vehicle, can bring the vehicle close to the fire site by automatic operation or remote control, and minimizes the occurrence of a water hammer when water is supplied. A hose reel is installed on a base which is installed on a vehicle, so as to be rotatable around a rotary shaft extending vertically, a hose having shape retaining property is spirally wound around the hose reel and around the rotary shaft, the lower end of the hose is connectable to a water discharge pump installed behind the vehicle, and the upper end of the hose passes through the rotary shaft of the hose reel and is connected to a water discharge nozzle installed at the upper position of the vehicle.

A fire suppression sprinkler device 100 includes a sprinkler bulb 140, a nozzle manifold 160, and a conduit 190 for supplying fluid to the nozzle manifold 160. The sprinkler device 100 is arranged so that breakage of the sprinkler bulb 140 permits fluid communication from the interior of the conduit 180 to the nozzle manifold 160. The nozzle manifold 160 is disposed about the conduit 190.

A fire suppression nozzle includes an outer tubular member, an inner tubular member co-cylindrical with the outer tubular member and extending through the outer tubular member, wherein the inner tubular member comprises a first chamber, and the outer tubular member and the inner tubular member cooperatively define a second chamber, multiple disc members extending radially outward relative to an outer surface of the outer tubular member, a first and second set of openings extending through the inner tubular member to fluidly couple the first chamber with the second chamber, and a first and second set of discharge openings extending through the outer tubular member to fluidly couple the second chamber with an external environment, wherein the first and second set of openings are longitudinally aligned with the first and second set of discharge openings.

A method of fuel tank inerting includes separating process air into nitrogen-enriched air and oxygen-enriched air with an air separation membrane. A vacuum is applied to the air separation membrane to produce a pressure differential across the air separation membrane. The vacuum is manipulated to vary the pressure differential and vary purity of the nitrogen-enriched air.

A new artificial intelligence and swarm intelligence method and system in simulated environments for autonomous drones and robots for suppression of forest fires, which foresees the simulation of swarm intelligence models in simulated environment for autonomous drones and robots for suppression of forest fires, performing the analysis of forest fires based on data and information on real time conditions or historical data, of a burning area, transforming same into a simulation environment to obtain a better strategy for firefighting, based on virtual reality environments for digital land, with a mixture of real and virtual images, using satellite/aerial images and combined maps of virtual reality, augmented and mixed. Thus, providing improvements and higher efficacy in combatting forest fires.

Systems and methods for fire suppression systems are disclosed. In one embodiment, the fire suppression system comprises a water supply system, a foam concentrate supply system, and a foam concentrate recovery system. The water supply system includes a water pump and a water supply line. The foam concentrate supply system includes a foam pump and a foam concentrate supply line, the foam concentrate supply line fluidly connected with the water supply system to facilitate mixing foam concentrate provided by the foam concentrate supply system with water provided by the water supply system. The foam concentrate recovery system includes a recovery pump fluidly connectable with the foam concentrate supply system to facilitate the extraction of foam concentrate from at least a portion of the foam concentrate supply system. The system and method can also include circulating foam concentrate to promote mixing and hinder the congealment of foam concentrate.

A controller for a motor vehicle having an internal combustion engine, and a device for detecting a fire in a fluid conduit, the device having a fluid state sensor for detecting a state variable of a fluid that is conducted in the fluid conduit, are provided. The determination of a fire situation is performed in a manner dependent on a signal of the fluid state sensor.
