A fire fighting blower (1) comprises a propeller (2) coaxially mounted in a tubular casing (3) for generating an axial airflow. The blower comprises an airflow guiding device (9) in the casing (3) for obtaining a concentrated air jet having a substantially ovalized section, it comprises within the tubular casing (3) an assembly of first deflectors (4) for concentrating the axial airflow and generating a concentrated axial air jet and an assembly of second deflectors (16, 17) for generating an air stream deflected from the concentrated axial air jet so that the concentrated air jet having an ovalized section is a combination of the concentrated axial air jet and the deflected air stream.

Various forms of a gyroscopically stabilised aerial vehicle are provided. The aerial vehicle comprises a jet turbine and or an electric motor coupled to a gyroscopic stabilisation assembly via a shaft assembly. In preferred embodiments the gyroscopic stabilisation assembly comprises a gyroscopic fan with alternating pivoting fan blades to provide controlled stable flight. The aerial vehicle is preferably configured for vertical take off and landing (VTOL) to enable it to be used in a wide variety of situations, including in relation to fighting fires with its exhaust gasses.

A fire containment device includes a fog or mist maker, which electrically connected to batteries and a power controller. The battery and power controller are electrically connected to a transformer, and one or more electrical outlet electrically connected to the transformer. One or more switches are built in the electrical circuit to turn on and off the power of fog or mist maker. A cover covers the frame to contain water or mixed water with fire extinguisher agent without leakage. And a transport assembly is used to transport the fire containment device by helicopter or crane truck. Fog or mist maker generates fog or mist from mixed water with extinguisher agent. The fog and mist carry fire extinguisher agent to the flame.

The present invention is directed to a portable fan for the use in firefighting and other ventilation use-cases. The portable fan provides firefighters the ability to provide positive pressure ventilation in use for fighting fires which does not require power cables or combustible fuel powered motors, and provides increased portability, reduced risk, and reduced deployment time associated with managing and fighting a fire.

A spray jet discharging device of long range, whose function is based on the production of a powerful air stream with liquid droplets dispersed therein, the maximum velocity of the spray jet being at least 300 km/h. The air stream is produced by a centrifugal fan with a spiral housing (1). The device is mainly used for fire extinguishing. It may be mounted at fixed points or on land vehicles via a suitable support for the fan, which enables both rotation of the spray jet beam in the horizontal plane, and changing of its inclination angle in the vertical plane. It may be remotely controlled (10) or manually operated (60). There is also a version of the device for aerial fire-fighting operations (90), configured to be suspended from an aircraft, e.g. a helicopter, and a device for portable use (1 10), which can be carried by a fireman.

A system for controlling and containing wildfires comprises a transport unit that is configured to transport the system to a site of a wildfire. At least one fluid-spraying apparatus is configured to spray and blow fluid at the wildfire for control and containment thereof. At least one linkage device is configured to movingly link the transport unit to a corresponding fluid-spraying apparatus. The transport unit is configured to control operation of the transport unit, linkage device, and fluid-spraying apparatus. The linkage device is configured to move with respect to the transport unit and the fluid-spraying apparatus is configured to move with respect to the linkage device such that the fluid can be sprayed multi-directionally for control and containment of the wildfire.

A fire prevention system for a building. The fire protection system has an inlet duct having an interior end and an exterior end. An air handler is disposed at the interior end of the inlet duct to provide air from outside the building to the air handler. A flame arrester is located at the exterior end of the inlet duct to prevent burning embers from entering the inlet duct. The fire protection system also includes an interior duct system for distributing air from the air handler through the building. Distribution vents in the interior duct system allow flow of air from the interior duct system to the interior of the building to raise the pressure in the building above the outside pressure. Exhaust vents to allow flow of air out of the building. Also, a method for fire prevention for a building exposed to a fire.

A system for extinguishing and suppressing a fire in an aircraft includes a precooler, a heat exchanger, a condenser, a gas separator, and an accumulator. The precooler is configured to receive a bleed air from an engine of the aircraft. The heat exchanger is fluidly coupled with the precooler. The condenser is configured to receive a cabin exhaust air from a passenger cabin of the aircraft. The gas separator is fluidly coupled with the condenser and is fluidly coupled with the heat exchanger. The gas separator is configured to generate a fire suppressing agent from the bleed air and the cabin exhaust air. The accumulator is fluidly coupled with the gas separator. The accumulator is configured to receive the fire suppressing agent.

A fire-fighting cannon for the management of fires, in particular in a waste disposal centre, comprises a fixed base constrainable to a ceiling or to a vertical wall of a room defining a corresponding lying plane, a tubular body extending along an emission direction of at least one jet of fire-fighting fluid. In particular, the tubular body is arranged below or alongside the fixed base with respect to a normal direction to the lying plane. The fire-fighting cannon further comprises movement means configured to orient the tubular body between a plurality of operating positions, including an initial position in which the emission direction has a predefined angle of inclination with respect to the normal direction. The movement means is configured to orient the tubular body also in a position of inversion in which the emission direction is parallel to the normal direction, so as to emit the jet of fire-fighting fluid in a zone of the ground arranged underneath the fire-fighting cannon if the fixed base is constrained to the ceiling, or in a zone with horizontal output if the fixed base is constrained to the wall.
