Abstract:
A desensitizer unit forming part of a rocket motor assembly and with the rocket motor thereof capable of experiencing a cook-off condition having a temperature within a first predetermined range, said rocket motor having a rocket case having a forward end, an exhaust end, and an interior in which a propellant charge capable of being desensitized is located, said desensitizer unit comprising:(a) an enclosure having an exit port and a fill port; (b) a cap which seals said fill port; (c) a fluid located in said enclosure and capable of desensitizing said propellant charge; (d) a plug placed in said exit port of said enclosure and having a melting point at a second predetermined temperature range which is less than said first predetermined temperature range; and (e) a tube connecting said exit port of said enclosure to said forward end of said rocket case; whereby when said rocket motor experiences said cook-off condition said plug has already melted and opened said exit port to allow said desensitizing fluid to flow down said tube into said rocket case so that said propellant charge is already desensitized.
