Ordnance neutralization method and device using energetic compounds
View Patent ↗This invention generally relates to a method and apparatus to neutralize ordnance, more specifically improvised explosive devices (IEDs) and unexploded ordnance (UXOs). The current invention provides a simple method to neutralize the ordnance by taking advantage of a new class of energetic materials that includes nano-thermites, binary thermites and additionally powdered thermites. In the invention, a projectile is loaded with the new class of energetic materials and fired into the ordnance. The impact causes the energetic materials to react in such a fashion that the explosive compound or other material within the IED or UXO is burned in a self-propagating mode without exploding. Hence, the ordnance is neutralized.
1. A device for neutralizing ordnance containing explosive material, said device comprising:
a projectile; and
an energetic material contained within said projectile, wherein said energetic material, in response to said projectile contacts and penetrates the casing of an ordnance containing explosive material, reacts with said explosive material within said ordnance in order to deflagrate said explosive material within said ordnance, wherein said energetic material includes a reducer and an oxidizer, both being formed in separate layers packed within said projectile.
2. The device of claim 1 , wherein said reducer is a metal and said oxidizer is a metal oxide.
3. The device of claim 1 , wherein said reducer is boron and said oxidizer is boron oxide.
4. The device of claim 2 , wherein said metal is selected from a group consisting of aluminum, magnesium, tantalum, zirconium, tungsten, hafnium, beryllium, and combination thereof.
5. The device of claim 1 , wherein said oxidizer is selected from a group consisting of bismuth trioxide, tantalum pentoxide, iron (III) oxide, iron (II,III) oxide, tungsten(IV) oxide, tungsten(VI) oxide, lead oxide, copper oxide, silver oxide, molybdenum trioxide and combinations thereof.
6. The device of claim 1 , wherein said reducer and oxidizer are selected from a group consisting of aluminum and bismuth trioxide, aluminum and molybdenum trioxide, aluminum and iron oxide, aluminum and tungsten oxide, aluminum and copper oxide, aluminum and tantalum oxide, and tantalum and tungsten oxide.
7. The device of claim 1 , wherein said reducer and oxidizer are separated by a barrier.
8. The device of claim 1 , wherein said reducer and oxidizer are formed in separate layers within said projectile in an interleaving manner.
9. A device for neutralizing ordnance containing explosive material, said device comprising:
a projectile; and
an oxidizer contained within said projectile, wherein said oxidizer, in response to said projectile contacts and penetrates the casting of an ordnance containing explosive material, reacts with said explosive material within said ordnance in order to deflagrate said explosive material within said ordnance.
10. The device of claim 9 , wherein said oxidizer is selected from a group consisting of bismuth trioxide, tantalum pentoxide, iron (III) oxide, iron (II,III) oxide, tungsten(IV) oxide, tungsten(VI) oxide, lead oxide, copper oxide, silver oxide, molybdenum trioxide and combinations thereof.
11. A device for neutralizing ordnance containing explosive material, said device comprising:
a projectile; and
an energetic material contained within said projectile, wherein said energetic material, in response to said projectile contacts and penetrates the casing of an ordnance containing explosive material, reacts with said explosive material within said ordnance in order to deflagrate said explosive material within said ordnance, wherein said energetic material includes a first metal and a second metal, both being formed in separate layers packed within said projectile, which is capable to react and form an intermetallic compound.
12. The device of claim 11 , wherein said intermetallic compound includes AlPd, RuAl, TiNi, FeAl and TiB 2 .
