Beschreibung
Zusammenfassung:The invention is directed to a co-layered propellant grain having an exposed outer surface, wherein said propellant grain comprises an outer layer comprising a slow-burning propellant composition located on essentially the entire outer surface of the grain, and an inner layer comprising a fast-burning propellant composition having a higher linear burning rate than said slow propellant composition; wherein said propellant grain has a structure such that after ignition, the inner layer becomes increasingly exposed at the outer surface
