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 method for forming an explosive device, comprising:
storing nitrous oxide in a first storage area;
storing fuel in a second storage area, said fuel being chemically isolated from the nitrous oxide; and
controllably mixing the nitrous oxide and the fuel to form an explosive mixture and maintaining the mixture as a liquid prior to detonating the explosive device.
2. The method of claim 1 , wherein the nitrous oxide is a gas.
3. The method of claim 1 , wherein the nitrous oxide is a liquid under high pressure.
4. The method of claim 1 , wherein the fuel is a solid selected from the group consisting of powdered graphite, plastics, metals and mixtures thereof.
5. The method of claim 1 , wherein fuel is a liquid selected from the group consisting of alcohols, paraffins, olefins, aromatics and mixtures thereof.
6. The method of claim 1 , wherein the first storage area is a tank for storing nitrous oxide.
7. The method of claim 1 , wherein the second storage area is a tank for storing fuel.
8. The method of claim 1 , wherein the second storage area includes a membrane for storing fuel.
9. The method of claim 1 , wherein the mixing comprises rupturing of a rupturable membrane positioned between the first and second storage areas.
10. The method of claim 9 , wherein the mixing comprises rupturing of the membrane by opening a normally closed valve wherein high-pressure gas pressurizes a storage area and ruptures the membrane.
11. The membrane of claim 9 , wherein the mixing comprises rupturing of the membrane by massive acceleration of the device.
12. The method of claim 1 , wherein the explosive device is a military weapon.
13. The method of claim 1 , wherein the explosive device is a pyrotechnic device.
14. The method of claim 1 , wherein the explosive device is a civil blasting explosive.
15. The method of claim 1 , wherein the ratio of fuel:nitrous oxide is from about 5:1 to about 1:100 by weight.
16. The method of claim 1 , wherein the mixing occurs before deployment of the explosive, as the explosive is being deployed, or after deployment of the explosive.
17. The method of claim 1 further comprising opening a valve to let the explosive fluid evaporate for deactivating prior to detonation of the explosive device.
18. The method of claim 17 , wherein the portion of nitrous oxide is combined with the portion of fuel prior to evaporation.
19. The method of claim 17 , wherein the opening of the valve is done autonomously by a timer, is done by a properly coded radio remote control, or is done manually.
