Abstract
Abstract This invention involves a means for dispersing submunitions from a cluster weapons system by utilizing a foamed propellant dispersion concept. The concept provides for the forced dispersion of clustered submunitions by high pressure gases generated rapidly and directly in the interstices of the submunition cluster by the controlled detonation of a propellant mixture containing cyclotetramethylenetetranitramine in a polyurethane foam.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
56 words
In a cluster weapon comprising a container and a multiplicity of submunitions positioned within said container as an unconfined cluster having interstices therebetween, the improvement which comprises having a gas generating, foamed, low density, polyurethane resin matrix positioned within and filling said interstices to form a quick acting mechanism for effecting the dispersion of said submunitions.
Claim 2
Dependent Claim
56 words
In a cluster weapon comprising a container and a multiplicity of submunitions positioned within said container as an unconfined cluster having interstices therebetween, the improvement which comprises having a gas generating, foamed, low density, polyurethane resin matrix positioned within and filling said interstices to form a quick acting mechanism for effecting the dispersion of said submunitions.
Claim 3
Dependent Claim
31 words
In a cluster weapon as defined in claim 1 wherein said matrix comprises an explosive mixture of about 60 percent by weight of cyclotetramethylenetetranitramine with the balance a foamed polyurethane resin.
