ODAB-500PMV Space-detonating aviation-bomb

Aerial bombs (AB) ODAB-500PMV consists of a warhead filled with liquid fuel, dispersing the charge, the container with the parachute system, the initiating charge and the release mechanism, the cutter, the cartridge device variable delay (CPL) and the detonation device, which consists of a predictor, B1 and B2 fuses, power supply, switching mechanism and the brake sensor (TAA).

The explosion at the epicenter of the shock front pressure is 30 bars, the damage radius is 30 meters. It consists of a thin housing, equipment, containers with parachute system and the detonation device U-563. Its ammunition is liquid piperylene volatile liquid. The head of the predictor is placed, a power supply, a switching mechanism and a fuse detonation device. The middle section is located piperylene - total weight of 145 kg, the central charge of explosives and 6 peripheral charges. In the rear, in a container, placed parachute system, the cutter, the secondary charge, fuse and the brake sensor.

When bombing from planes and helicopters taking advantage of the CPL at the time of separation from the bombs of the aircraft (helicopter) electrical current pulse is applied to the CPL. After the set delay time at CPL electrical pulse is fed to the detonation device (slave). After the electric pulse to the slave is the launch of the power supply and the clock mechanism, and carried out a given program is TDM switching electric circuits.

After a certain time the parachute system opens and fires a certain distance unwinding the harness that connects the mechanical and electrical with the AB, engines fuses B1 and B2 are installed in the firing position. When meeting with an obstruction the charge explodes conventional explosives. At a meeting with the leader or bombs inertial barrier triggered contactors leader or fuse B1, triggering the firing circuit fuses B1 and B2. From pulse fuse B1 occurs undermining dispersing charge. As a result, his body collapses triggering the warhead, is crushed and throwing the liquid fuel to form a fuel-air cloud.

This leads to the destruction of a thin-walled body bomb explosive sublimation liquid to a gaseous state and the creation of the aerosol cloud, which is able to penetrate into the leaking (trenches, bunkers, and others.) Shelter. After a certain period of time triggered fuse B2, which undermines the initiation charge. After initiation of 100-140 milliseconds explodes the detonator, located in the capsule, attached to a parachute and there is an explosion of fuel-air mixture. From the response of the initiating charge cloud detonation occurs with the formation of a shock wave high power that strikes the target.

The main factor affecting ODAB a shock wave in front of which an overpressure can reach about 3000 kPa (30 kg / cm). It has a long time the vacuum zone, in connection with what is sometimes called vacuum ODAB and effectively affects manpower, including where it is sheltered from the effects of oskololkov. The effective radius of the defeat enemy personnel in open terrain is 30 meters, field fortifications and trenches - 25 meters, unsheltered aviation technology on parking 30 meters.

ODAB-500PM may be all the tactical combat aircraft, operated by the Russian Air Force. List of aircraft carriers includes Su-24, Su-25, Su-27, MiG-29 and Mi-24 helicopter: aircraft bombs ODAB-500PMV bombing by planes has been tested in the treatment process. The use of bombs from airplanes as a possible without the involvement of the CPL (with heights ranging from 200 to 600 m), as well as taking advantage of the CPL (with heights of 400 m and above). The use of bombs from helicopters is possible only with the activation of the CPL. Aerial bombs ODAB-500PMV is all-altitude and applied as from planes and helicopters, equipped with an electric control system fuses.

The development of fuel-air explosives by American designers began approximately in 1960. For a long time these works were of the laboratory character. It was also found that the explosion of a bomb containing about 32-33 liters of ethylene-fuel mixture cloud is formed radius and a height of 7.5-8.5 m to 3 m monoxide. After its 125 milliseconds after detonation shock wave formed with excess pressure on the front that could be created at a distance of 8 m at 200-250 kg of TNT explosion. This bomb was capable of within a radius of 30-40 meters from the blast site permanently damage the aircraft or helicopter in the parking lot. They were tested and found suitable for use as explosives bomb blast volume of ethylene oxide, propylene oxide, methane, propyl nitrate, MAPP (a mixture of methyl acetylene, propadiene, and propane).

Attempts to create a larger ammunition due to technical difficulties were not successful. Therefore, cluster bombs were created with several bombs surround explosion caliber 32.6 kg. Simultaneous use of their increased size of the cloud and the total attack area.

Typical volumetric bomb detonating consiste of a container with two separate reagent and explosive charges. After discharge the first charge opens the container at a certain height, the reagent is sprayed and mixed with atmospheric oxygen creates an explosive aerosol cloud. The size of the cloud depends on the amount of reagent. The resulting mixture encapsulating objects and penetrates the structure. After a while there is the undermining of the clouds the second charge, resulting in a powerful shock wave that destroys unfortified buildings, equipment and personnel of the strikes. Effects on humans is amplified in single trench or personal protective equipment and in enclosed spaces (in mountain caves, buildings, bunkers, etc.).

In the USSR, a similar weapon was created in a short time and was used during the border conflict with China (1969) and in Afghanistan. Currently, the Russian army has a wide arsenal of space-detonating ammunition third generation.

Currently, munitions of this type are KAB-500Kr-OD (body-bomb detonating action with telenavedeniem), SLM-OD BLU (8 container volume and cluster bombs detonating action), 220 and 300-mm MLRS 9A52-2 "Twister "9P140 and" Hurricane " helicopter ATGM "Storm" and "Attack", applying missiles with warheads volume-detonating action, as well as 80-mm aircraft missile S-8D (C-8DM) with a head portion having a similar effect.
