Nitrous oxide based explosives and methods for making same
An explosive device and methods for forming same, the device comprising a portion of nitrous oxide and a portion of fuel. In one example, the explosive device may include a first storage area containing said portion of nitrous oxide, and a second storage area containing said portion of fuel, wherein the first storage area selectively maintains the portion of nitrous oxide separated from the fuel in the second storage area prior to detonation of the explosive device. In another example, in the event the explosive fails to detonate, the explosive device may include a vent valve for discharging the nitrous oxide from the explosive device to reduce or eliminate its explosive characteristics. The explosive device can be used for various applications, including but not limited to military weapons, pyrotechnic devices, or civil blasting explosives, for example.
1. A military explosive device, comprising:
a portion of liquid nitrous oxide;
a first storage area containing said portion of nitrous oxide;
a portion of liquid fuel;
a second storage area containing said portion of fuel,
wherein the ratio of nitrous oxide:fuel is from about 20:1 to about 5:1 by weight,
wherein the nitrous oxide and fuel when mixed are miscible,
wherein the first storage area selectively maintains the portion of nitrous oxide separated from the fuel in the second storage area prior to detonation of the explosive device, and mixing of the nitrous oxide and fuel to form an explosive mixture is
(a) by a rupturable membrane or
(b) by a normally closed valve located within conduit coupling the first and second storage areas, and wherein the explosive mixture is maintainable as a liquid prior to detonation of the device.
2. The explosive device of claim 1 , wherein the first storage area is a tank for storing the portion of nitrous oxide.
3. The explosive device of claim 1 , wherein the second storage area is a tank for storing the portion of fuel.
4. The explosive device of claim 1 , wherein the second storage area includes a membrane for storing the portion of fuel.
5. The explosive device of claim 1 , wherein the portion of fuel is selected from alcohols, paraffins, olefins, aromatics and mixtures thereof.
6. The explosive device of claim 1 , wherein the nitrous oxide is stored in the first storage area.
7. The explosive device of claim 1 , wherein the explosive device is a military weapon.
8. The explosive device of claim 1 , wherein the explosive device is a pyrotechnic device.
9. The explosive device of claim 1 , wherein the explosive device is a civil blasting explosive.
10. The explosive device of claim 1 , further comprising:
a vent valve for discharging the nitrous oxide from the explosive device.
11. An explosive liquid mixture for use as a military device consisting essentially of liquid nitrous oxide and a liquid fuel, wherein the ratio of nitrous oxide:fuel is from about 20:1 to about 5:1 by weight, wherein the nitrous oxide and fuel are miscible, and
wherein the nitrous oxide and fuel are mixed to form the explosive liquid mixture and the explosive mixture is maintainable as a liquid prior to detonation of the device.
12. The mixture of claim 11 , wherein the fuel is selected from alcohols, paraffins, olefins, aromatics and mixtures thereof.
13. The mixture of claim 11 , wherein the nitrous oxide is under high pressure.
14. The explosive device of claim 1 , wherein the means for mixing includes a rupturable membrane positioned between the first and second storage areas.
15. The explosive device of claim 1 , wherein the second storage area includes a membrane for storing the portion of fuel.
16. The explosive device of claim 14 , wherein the membrane is capable of rupture at a pre-set time to initiate mixing between the first and second storage areas.
17. The explosive device of claim 14 , wherein the membrane is capable of rupture upon acceleration of the explosive device to initiate mixing between the first and second storage areas.
18. The explosive device of claim 1 , wherein the ratio of nitrous oxide:fuel is from about 20:1 to about 10:1 by weight.
