Abstract

See full text

A propellant manufacturing method for manufacturing a propellant including a propellant grain having a first surface on which combustion starts upon ignition and a second surface to be coupled to a wall surface that prevents combustion. The manufacturing method includes placing a portion of first propellant having a first burning rate in a first space containing a first position on the second surface; and placing a portion of second propellant having a second burning rate higher than the first burning rate in a second space containing a second position on the first propellant. The method further includes placing a portion of third propellant having a third burning rate higher than the second burning rate in a third space containing a third position on the first propellant. The method further includes completing the propellant grain by simultaneously hardening the entireties of the first propellant, the second propellant, and the third propellant.
