ABSTRACT:
A rocket motor having case segments which are attached together. A retaining member extends circumferentially thereabout to maintain attachment of the segments together. The retaining member is characterized by sensitivity to a predetermined temperature greater than ambient temperature and less than the ignition temperature of propellant material in the rocket motor to lose strength whereby the retaining member is released and the rocket motor may safely be rendered non-propulsive during a hazard such as a fuel fire or slow cook-off.
