Abstract

Abstract A binary munition system comprising at least two non-explosive ingredients that combine in flight to form a relatively safe explosive. The combination of said non-explosive ingredients for the purpose of forming safe explosives is novel. The binary munition stores the non-explosive ingredients in separate compartments which utilize membranes, bags or containers to facilitate the separation. The munition is equipped with means in which to rupture the compartments upon launch or fire. The purpose of the munition is to maintain separation of the non-explosive ingredients and to achieve mixing of the ingredients upon launch or fire of said munition.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 30 words
An explosive consisting essentially of an effective amount of non-explosive ingredients which combine upon mixing to produce a safe explosive, wherein said non-explosive ingredients are ethylene diamine and nitric acid.
Claim 2
Dependent Claim 30 words
An explosive consisting essentially of an effective amount of non-explosive ingredients which combine upon mixing to produce a safe explosive, wherein said non-explosive ingredients are ethylene diamine and nitric acid.
Claim 3
Dependent Claim 28 words
An explosive comprising an effective amount of non-explosive ingredients which combine upon mixing to produce a safe explosive, wherein said non-explosive ingredients are isopropylamine, hydroxylamine and nitric acid.
Claim 4
Dependent Claim 28 words
An explosive comprising an effective amount of non-explosive ingredients which combine upon mixing to produce a safe explosive, wherein said non-explosive ingredients are isopropylamine, hydroxylamine and nitric acid.
Claim 5
Dependent Claim 36 words
An explosive as set forth in claims 1 or 3, wherein said explosive may further comprise an effective amount of ammonium nitrate to be added to the nitric acid for increased performance of the safe explosive.
Claim 6
Dependent Claim 36 words
An explosive comprising an effective amount of non-explosive ingredients which are housed separately and which combine upon mixing to produce a safe explosive, wherein said separately housed, non-explosive ingredients consist essentially of hydrazine and ammonium nitrate.
Claim 7
Dependent Claim 36 words
An explosive comprising an effective amount of non-explosive ingredients which are housed separately and which combine upon mixing to produce a safe explosive, wherein said separately housed, non-explosive ingredients consist essentially of hydrazine and ammonium nitrate.
Claim 8
Dependent Claim 41 words
An explosive comprising an effective amount of non-explosive ingredients which combine upon mixing to produce a safe explosive, wherein said non-explosive ingredients are hydroxylammonium nitrate, triethanolamine nitrate and water; said water content in said explosive in less than 10.0 wt. percent.
Claim 9
Dependent Claim 41 words
An explosive comprising an effective amount of non-explosive ingredients which combine upon mixing to produce a safe explosive, wherein said non-explosive ingredients are hydroxylammonium nitrate, triethanolamine nitrate and water; said water content in said explosive in less than 10.0 wt. percent.
Claim 10
Dependent Claim 24 words
An explosive as set forth in claim 5, comprising 72.8 weight percent hydroxylammonium nitrate, 23.1 weight percent triethanolamine nitrate and 4.1 weight percent water.
Claim 11
Independent Claim 34 words
A method of producing a safe explosive, herein an effective amount of two or more non-explosive ingredients are combined upon firing or launch of a munition separately housing said non-explosives to form an explosive.
Claim 12
Independent Claim 34 words
A method of producing a safe explosive, herein an effective amount of two or more non-explosive ingredients are combined upon firing or launch of a munition separately housing said non-explosives to form an explosive.
Claim 13
Dependent Claim 16 words
A method as in claim 7, wherein said non-explosive ingredients are ethylene diamine and nitric acid.
Claim 14
Dependent Claim 16 words
A method as in claim 7, wherein said non-explosive ingredients are isopropylamine, hydroxylamine and nitric acid.
Claim 15
Independent Claim 29 words
A method as in claims 8, or 9, wherein an effective amount of ammonium nitrate may be added to the nitric acid for increased performance of the safe explosive.
Claim 16
Dependent Claim 15 words
A method as in claim 7, wherein said non-explosive ingredients are hydrazine and ammonium nitrate,
Claim 17
Dependent Claim 30 words
A method as in claim 7, wherein said non-explosive ingredients are hydroxylammonium nitrate, triethanolamine nitrate, and water; wherein said water content in said explosive is less than 10.0 wt. percent.
Claim 18
Dependent Claim 27 words
A method as in claim 12, wherein said non-explosive ingredients consist of 72.8 wt. percent oxylammonium nitrate, 23.1 wt, percent triethanolamine nitrate and 4.1 wt, percent water.
