Abstract
A propellant burning system and method useful in a rocket motor or projectile firing device burns a continuous main propellant grain of relatively soft propellant material selected from uncatalyzed or partially catalyzed propellants. A separating device divides the propellant grain into a large number of fragments of high-surface area during the burn and an activation mechanism for causing said separating device to operate on the main propellant grain and to ignite and control the burning thereof.
Claims13
A main propellant burning system for a rocket motor or projectile firing device comprising:
- (a) a propellant grain of relatively soft propellant material selected from the group consisting of uncatalyzed or partially catalyzed propellants;
- (b) a shredding device for dividing said propellant grain into a large number of fragments of high-surface area;
- and
- (c) activation mechanism for causing said separating device to operate on said main propellant grain and to ignite and control the burning thereof.
