ABSTRACT:
A method of making solid rocket propellant that facilitates tailoring of a variable burn rate. The method comprises molding binder and fuel and/or oxidizer to produce, for example, a molded strip of solid rocket propellant material. The molded solid rocket propellant material is formed into a desired shape by, for example, filament winding. In a preferred aspect, the solid rocket propellant is cured prior to being encased in a rocket motor casing. This improves rocket propellant to rocket engine casing bonding. Yet another aspect of this invention is a method of making solid rocket propellant comprising forming binder and oxidizer into separate strips and combining the binder and oxidizer strips to form solid rocket propellant material.
