Abstract:Safety firing apparatus is the important facility which assures the safety of shipborne weapon equipment and the achievement of combat mission. In order to ensure the ship safety and launch reliability in the operational process, the demand analysis of safety firing apparatus is carried out, the units of safety firing boundary are designed, the hardware and software architecture are built, and the basic functions of each software module are devised in details. On the basis of the contour curve measurement of a weapon system, the effectiveness of stop-shooting hysteresis to safety firing zones and launch device are analyzed, the maximum lag angle is calculated, the gap value of shooting forbidden curve is determined, the emission reliability and safety is verified, finally, provide the reference for the similar system design of safety firing apparatus.
