A practical model for calculating the lethal action field of a controlled fragmentation warhead is established. According to space-coordinate transformation rules, fragment parameters between the warhead coordinate and ground coordinate systems are transformed. Using energy criterion and fragment distribution density criterion, the lethal area of warhead is determined. The model can be used to select warhead schemes during the design process and to evaluate or calculate lethal power of a fragmentation warhead.
