Aerial dispersion systems that may be employed to allow rapid and temporary conversion of aircraft for aerial dispersion purposes, such as aerial fire-fighting. The aerial dispersion systems may be implemented using modular components that may be configured for compatibility with conventional cargo loading and unloading systems of modern aircraft, including side-loading cargo systems of wide body passenger and cargo aircraft having high lift capacities. The aerial dispersion systems may be rapidly installed in a large fleet of high capacity aircraft in response to a wildfire or other rapidly-developing emergency such as an oil spill, chemical or biological contamination incident, building or refinery fire, etc. After use, the aircraft of the fleet may be rapidly de-modified and returned to original condition. The aerial dispersion systems may be operated with a fleet of aircraft in a coordinated manner, for example, as part of an aerial firefighting formation having multiple aircraft sharing information and / or common control.

A large size fire blanket folded in one pack is provided and delivered to the area of wild fire over the air by manned or unmanned aircrafts. Being deployed over the air to the wild fire area, the fire blanket attached to aircrafts is unfolding above the fire by stretching it out with aircrafts slowly moving apart until fire blanket is fully unfolded. After that the aircrafts starts simultaneous landing and covering with fire blanket the affected area. In result the fire blanket cuts off oxygen flow to the fire area and extinguish fire therefore. To prevent “hot air balloon” effect, the fire blanket has multiple perforations equally spread along the surface.

The invention employs a blower of the type used by commercial landscapers. The device has an engine mounted on a frame. Shoulder straps attached to the frame allow the user to wear the device on his back leaving the hands of the operator free to operate other tools such as a chain saw or perform other tasks. Also, wearing the device on the back makes it easier to transport the device over long distances to the source of the fire or backfire to be started.The device's blower generates a stream of air at high speeds. This stream of air can be used to feed a fire when the air is directed at a fire. When used to extinguish a fire, air from the blower is tapped from a point 180 degrees removed from the blower output and mixed with exhaust from the engine. This mixture is diverted through a Y-shaped valve into the airstream coming out of the blower. When the device is used to start backfires a fire is started. The airstream, without the mixture of air and engine exhaust can be used to both encourage the propagation of the fire and direct the fire towards the main wild fire. The ability to quickly spread the backfire in the proper direction is imperative because a sudden change in wind direction or other weather conditions could cause the backfire to become as big a problem as the original fire.
