Abstract
A propellant grain composition for use in solid fuel rocket engines comprises a first reactant component consisting of an oxidizer. A polymeric barrier coating encapsulates the first reactant component and a second reactant component comprising a reducer fuel reactable with the oxidizer is coated thereon, A final polymeric coating is placed over the entire propellant grain to yield a unitary metal fuel-oxidizer propellant grain structure for use as a solid rocket fuel.
