propellantcompositionmethod

The patent describes a method for enhancing propellant compositions by flowing an inert gas through an uncured mixture to eliminate dissolved gases. This process aims to improve the performance and stability of the propellant by ensuring a cleaner composition.

Claim 1

1 . A method for removing a gas from a propellant composition, the method comprising: providing an uncured propellant composition comprising a bonding agent, energetic particles, and polymeric binder; and flowing an inert gas at room temperature through the uncured propellant composition to remove an evolved gas from the uncured propellant composition. providing an uncured propellant composition comprising a bonding agent, energetic particles, and polymeric binder; and flowing an inert gas at room temperature through the uncured propellant composition to remove an evolved gas from the uncured propellant composition.
