What is the vacuum bomb?

Answer 1

It is a two stage explosive device.
During the first stage a fuel is being atomized over a large area and being mixed with air forming a volatile mixture. The second stage then ignites that mixture. Since it uses oxygen from the surrounding air during the detonation a partial vacuum is created.

Answer 2

Vacuum Bomb

Answer 3

As has been stated the Vacuum Bomb is what the US military calls an air burst or Hellfire weapon.
The device contains a lot of liquid fuel which is dispersed as a fine mist by the initial small explosion. This large cloud of fuel vapour is ignited by a second charge and the resultant very hot fire ball incinerates everything in its vicinity. The fireball eats up all of the oxygen and heats the rest to hundreds of degrees C. When the hot gas rapidly cools it forms a partial vacuum and the resulting inrush of air reaches supersonic speeds, the sonic shockwave destroys anything left standing.

Answer 5

Vacuum bomb or thermobaric weapons distinguish themselves from conventional explosive weapons by using atmospheric oxygen, instead of carrying an oxidizer in their explosives. They are also called high-impulse thermobaric weapons (HITs), fuel-air explosives (FAE or FAX) or sometimes fuel-air munitions, heat and pressure weapons, or vacuum bombs. They produce more explosive energy for a given size than do other conventional explosives, but have the downside of being less predictable in their effect.
A thermobaric weapon works by first dispersing a cloud of powder or liquid explosive using a small charge, then igniting it with a second charge.

The weapon consists of a container of either a volatile liquid or a finely powdered solid, which could be an explosive or metal powder, and two separate explosive charges.

The weapon is initiated upon dropping or firing, and the first explosive charge (or some other dispersal mechanism) bursts open the container at a predetermined height and disperses the fuel in a cloud that mixes with atmospheric oxygen. Once the fuel is appropriately mixed, the second charge detonates, propagating an explosion (blast wave) through the cloud.

Newer types of thermobaric weapons do not disperse the fuel before igniting it, but are single-stage bombs having one explosive charge that both ignites and disperses the fuel.
Fuel-air explosives represent the military application of the vapor cloud explosion and dust explosion accidents that have long bedeviled a variety of industries. An accidental fuel-air explosion may occur as a result of a boiling liquid expanding vapor explosion (BLEVE), for example when a tank containing liquified petroleum gas bursts. Silo explosions, caused by the ignition of finely-powdered atmospheric dust, are another example.

Fuel-air explosives disperse an aerosol cloud of fuel which is ignited by an embedded detonator to produce an explosion. The rapidly expanding wave front due to overpressure flattens all objects within close proximity of the epicenter of the aerosol fuel cloud, and produces debilitating damage well beyond the flattened area. The main destructive force of FAE is high pressure. More importantly, the duration of the overpressure gives it an edge over conventional explosives and makes fuel-air explosives useful against hard targets such as minefields, armored vehicles, aircraft parked in the open, and bunkers.

There are dramatic differences between explosions involving high explosives and vapor clouds at close distances. For the same amount of energy, the high explosive blast overpressure is much higher and the blast impulse is much lower than that from a vapor cloud explosion. The shock wave from a TNT explosion is of relatively short duration, while the blast wave produced by an explosion of hydrocarbon material displays a relatively long duration. The duration of the positive phase of a shock wave is an important parameter in the response of structures to a blast.

The effects produced by FAEs (a long-duration high pressure and heat impulse) are often likened to the effects produced by low-yield nuclear weapons, but without the problems of radiation. However, this is inexact; for all current and foreseen sub-kiloton-yield nuclear weapon designs, prompt radiation effects predominate, producing some secondary heating; very little of the nominal yield is actually delivered as blast. The significant injury dealt by either weapon on a targeted population is nonetheless great.

Some fuels used, such as ethylene oxide and propylene oxide, act like mustards. A device using such fuels can be dangerous if the fuel fails to completely ignite; the device is at risk of producing the effects of a chemical weapon.
