METHOD AND ARRANGEMENT FOR PREVENTING ENCASED EXPLOSIVES BEING CAUSED TO EXPLODE BY AN EXTERNAL FIRE

摘要

This disclosure relates to a method and an arrangement for preventing explosives such as rocket engines from exploding while subjected to an external fire in an ammunition bunker. The basic principle underlying the invention is that the casing surrounding the explosive includes a number of parts which are held together by mounting components made from a shape memory alloy, the properties of which are selected in such a manner that these mounting components no longer hold the various parts of the casing together if the surrounding temperature rises to approach the ignition temperature of the explosive in the rocket engine.
