How does a thermobaric work?

Thermobaric munitions are those munitions that, by design, produce more heat and overpressure than conventional explosives by exploding a vapour in the blast zone. Their main use initially was in airborne fuel-air explosive bombs.

How does a fuel-air bomb work?

The devices use a small charge to generate a cloud of explosive mixed with air. The main explosion is then detonated by a second charge (a fuel-air explosion), or by the explosive reacting spontaneously with air (a thermobaric explosion).

What is a thermobaric charge?

Definition of thermobaric of a weapon. : containing a charge of fuel designed to ignite and combine with oxygen present in the atmosphere to produce a prolonged explosion Rather than fight their way into such caverns, U.S. forces have preferred to drop specialized …

How powerful is a thermobaric bomb?

The thermobaric device yields the equivalent of 44 tons of TNT using about seven tons of a new type of high explosive. Because of this, the bomb’s blast and pressure wave have a similar effect to a small tactical nuclear weapon. The bomb works by detonating in mid-air.

Do explosions create a vacuum?

All explosions create a vacuum space. Due to the expansion of vacuum space, shock wave occur (figure 3). Figure 3. Area expansion during the explosion.

What bomb was used in outbreak?

In 1995, when this film was made, the most powerful non-nuclear weapon in the U.S. arsenal was the BLU-82 “Daisy Cutter,” which is indeed the bomb shown in the film, but which is not a fuel-air bomb.

Has MOAB ever been used?

On 13 April 2017, a MOAB was dropped on an ISIS-Khorasan cave complex in Achin District, Nangarhar Province, Afghanistan. It was the first operational use of the bomb. Bush administration, said that the US had not previously used the MOAB because of worries that it would inadvertently hurt or kill civilians.

How does the mother of all bombs work?

Unlike a bomb designed to actually penetrate a building or the ground, the MOAB (also called a fuel-air bomb) has a “proximity fuse” on its nose that ignites the warhead when it reaches a certain altitude—which might be anywhere between 50 and 1,000 feet—says Edward Priest, a former Air Force Special Operations combat …

Does temperature affect explosion?

Explosive conditions may be created when fuel evaporation and mixing with air occur. At temperatures higher than the flash point, liquid evaporation may result in the formation of a flammable cloud that, in turn, may give rise to explosion (the so-called “vapor cloud explosion”).

Do nukes make craters?

Most damage comes from the explosive blast. When a nuclear weapon is detonated on or near Earth’s surface, the blast digs out a large crater. Some of the material that used in be in the crater is deposited on the rim of the crater; the rest is carried up into the air and returns to Earth as radioactive fallout.

How big is a FOAB blast radius?

roughly three hundred meters
If Russia’s reported specifications are true, then the FOAB, which has a payload equivalent to forty-four tons of TNT and blast radius of roughly three hundred meters, would be the most powerful non-nuclear bomb in the world, with destructive potential close to that of a tactical nuke.

What is thermobaric weapon fuel made of?

In a thermobaric weapon, the fuel consists of a monopropellant and energetic particles [3]. In operation, the aerosol is detonated within a micro/millisecond in a manner similar to a conventional explosive like TNT or RDX.

Do thermobaric weapons really have enhanced blast performance?

New technologies have been developed now for warheads that claim to possess enhanced blast performance. Thermobaric weapons are classified as a subcomponent of a larger family of weapon systems which are commonly known as volumetric weapons.

What are thermobaric munitions and their medical effects?

MUNITIONS – Thermobaric Munitions and their Medical Effects! Thermobaric munitions are those munitions that, by design, produce more heat and overpressure than conventional explosives by exploding a vapour in the blast zone. Their main use initially was in airborne fuel-air explosive bombs.

What are thermobaric explosives (TBX)?

Recently, some thermobaric explosives (TBX) which are particularly highly metal-based systems have been successfully designed to exploit the secondary combustion which is responsible for the sustained overpressure and additional thermal effects [6], [7].
