Abstract
A propellant system is disclosed which includes a propellant applied to at least one surface of a substrate which is in the form of a strip. The propellant strip is adhesively attached to itself in a configuration which conceals propellant within the configuration and which allows the attached strip to peel away from itself under applied forces thereby resulting in smooth and continuous exposure of propellant for burning. The system is directed to use with ejectable projectiles which are slidably disposed within a canister or casing. The propellant system is interconnected between the projectile and the cannister which houses the projectile. The propellant is urged to peel, and thus expose propellant for burning, as the projectile is ejected from the canister. Alternatively, the propellant is telescoped and covered with a sleeve which peels away as the projectile is ejected.
