  • Patent number: 11958790
    Abstract: 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 burn rate than said slow burning propellant composition; wherein said propellant grain has a structure such that after ignition, the inner layer becomes increasingly exposed at the outer surface.
    Type: Grant
    Filed: August 20, 2018
    Date of Patent: April 16, 2024
    Assignee: Nederlandse Organisatie voor toegepast-natuurwetenschappelijk onderzoek TNO
