Abstract
Rocket motors are constructed by encasing a solid porous poly(vinyl alcohol) core in the shape of the propellant grain with motor casing material in the same manner as motor casing material is conventionally applied over a disposable or removable mandrel. The motor is then completed by filling the open passages of the core with liquid oxidizer. When the liquid oxidizer permeates the poly(vinyl alcohol), the result is a solid continuous propellant grain of rubbery consistency. Aluminum powder may be incorporated in either the porous poly(vinyl alcohol) or the liquid oxidizer to achieve a fuel-enhanced propellant.
