Abstract: A representative embodiment of the invention provides a MEMS-based safety and arming (S&A) device having a shuttle movably connected to a frame by one or more bowed springs. The device has an electrical path adapted to electrically connect the frame and a contact pad. In the initial state, the electrical path has an electrical break. If the inertial force acting upon the shuttle (e.g., during launch) reaches or exceeds a first threshold value, then displacement of the shuttle with respect to the frame causes the electrical break to close. If the inertial force reaches or exceeds a second threshold value greater than the first threshold value, then a latching mechanism employed in the S&A device latches to keep the electrical break irreversibly closed thereafter.

Abstract: Ammunition with structural and functional features such as to optimise the propellant combustion process when the weapon is fired, resulting in accelerated delivery of the combustion gases. For this purpose, advantageously, the ammunition at issue is fitted with an innovative firing system (4), the incendiary operation of which allows to ignite the entire quantity of propellant (7) in a homogeneous and capillary manner. In this operational circumstance, a considerably larger quantity of propellant (than that occurring with the known art) is therefore ignited in a shorter time. This results in accelerated delivery of the gases, such as to transmit to the projectile (5) an extremely fast burst of thrust, resulting in greater ballistic yield of the projectile and greater damage to the target.
