Method and device for destroying solid propellant motors

摘要

The method involves cutting a scrapped solid propellant engine into sections, and withdrawing sections that do not contain propellant. The sections containing propellant are cooled at a very low temperature by immersing it in a cryogenic liquid. The propellant is fragmented and separated from the envelope of each section. The sections of empty envelope are collected for deactivating residues. An independent claim is also included for an installation for the destruction of a solid propellant engine.
