АSP-500 Fire-extinguishing Air System
is intended for localizing forest fires and for suppressing fire storms during technogenic calamities and disasters over areas of up to 1000 sq m at an ambient air temperature in carrier take-off zone and in the fire centre of - 5°С to + 45°С under any weather conditions. At this, failure-free operation probability is 0.97 min. In terms of costs efficiency the air systems intended for delivery of a fire-extinguishing mixture (water) are considerably superior to other traditional delivery means such as artillery (by 70 times) or rocket systems (by 300 times). Application of traditional discharging fire-extinguishing air systems results in only minor amounts of dropped fire-extinguishing mixture reaching the fire zone.This is because of fire zone screening with hot air ascending convection current, as a result the required accuracy of water mass drop centre grouping with relation to the fire location cannot be ensured.

АSP-500 ensures a 100 percent delivery of fire-extinguishing compound to the fire zone, furthermore, explosive method of compound dispersing creates an airborne shock wave as an additional effect.
АSP-500 can be filled both at field or at factory facilities. ASP-500 makes it possible to involve military aircraft in accomplishing missions aimed at fire extinguishing without extra expenditures for fixed-wing or rotary-wing aircraft fleet modifications and without ingaging extra-fire brigades and special-purpose equipment. FSUE "SRPE "Bazalt" is in a position to offer its technology of ASP-500 utilization from the civil aviation aircraft (IL-76 or AN-12). The proposed technology will ensure ASP-500 massed applocation. One carrier aircraft is capable of delivering over 100 systems to the fire zone with fire extinguishing over an area of 10 plus hectares. The problem of safety assuring is solved both through the design solution and due to the elimination of dangerous fragmentation and blast effects beyond the aerosol cloud, as well as owing to organizational measures determining the bomb application procedure.
ASP-500 can be efficiently used in radioactive contamination regions as it permits to eliminate or to significantly reduce firemen direct contact with radioactive products of forest combustion.
Application of ASP-500 as a first-strike measure for suppressing intense burning will allow for rapid suppressing of the most dangerous fire zones thus reducing the intensity of ascending air convection current which prevents the precipitating of aerosol resulting at liquid direct drop from the currier aircraft.In doing so, the efficiency of subsequent use of traditional discharging systems can by improved tenfold. Thus, the combined application of ASP-500 and systems of direct liquid (mixture) drop from the carrier fixed-wing or rotary-wing aircraft ensures the maximum efficiency at extinguishing fires over wide areas.
