Patent ID: 7051658

Claim:
A propellant, comprising at least one grain and a plug, wherein said at least one grain has a diameter of at least 3 mm and has at least one hollow chamber that discharges with an opening to an outside surface of the grain, wherein the opening has a diameter of 0.03 mm to 0.5 mm and is closed off with said plug, wherein the plug comprises a non-volatile solid material and a moderator wherein the plug is formed, in a polishing drum, in which the grain is subjected to surface treatment in combination with an amount of solid material of 0.085 to 0.4 wt % relative to the weight of the grain and an amount of moderator of 0.05–0.5 wt % relative to the weight of the grain; wherein the plug has a temperature dependent mobility, meaning it has a higher mobility for a lower deployment temperature than for a higher deployment temperature, so that the plug permits a stronger hole burning at a lower deployment temperature than at a higher deployment temperature.
