Patent number: 6558488Abstract: The invention relates to a method of making pourable, plastic-bound explosive charges or rocket propellants, to which a metal powder having essentially spherically shaped grains is added. To avoid an increase in the viscosity of the explosive charge or the rocket propellant through polar groups attached to the surface of the metal powder, it is suggested according to the invention that the polar groups of the metal powder be saturated with SiR3 groups (Si=silane; R=organic residue) before the metal powder is added to the explosive mixture. As a result, the polar groups can no longer react with the isocyanates of the explosive charge or the rocket propellant and the specific surface of the respective metal powder, as well as the viscosity of the charges, is reduced.Type: GrantFiled: February 20, 2002Date of Patent: May 6, 2003Assignee: Rheinmetall W & M GmbHInventors: Paul Wanninger, Rainer Böhm, Horst Pinkernelle

Patent number: 6183574Abstract: A processing procedure for incorporating bismuth compounds into isocyanate cured hydroxy terminated binder propellants has been discovered. When added to the propellant formulation in ballistic modifier amounts (≧0.25%), bismuth salicylate and bismuth &bgr;-resorcylate significantly reduce the potlife to less than 1-hour. It was discovered that to maximize propellant potlife the temperature of the mixture at the time of the addition is critically important. The potlife of propellants containing bismuth compounds can be increased to greater than 15 hours at 70° F., when the temperature of the mixture at the addition step for bismuth, is lowered from the normal addition temperature of 150° F., to 60° F. Depending on the formulation and solids loading, the viscosity of the propellant at 60° F. is not greatly affected.Type: GrantFiled: September 2, 1999Date of Patent: February 6, 2001Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Larry C.
