Evaluation method of combined blockage efficiency of anti-runway warhead and zone blockage warhead carried by dispenser

To study the evaluation method of efficiency of combined anti-runway warhead and zone blockage warhead blockading airport runway, the method to judge the efficiency of blockading airport runway was presented based on three criteria, such as the criteria for judging the destruction of airport runway by checking whether the minimum flying area is still existing, the time criteria of preventing the repair of craters within the minimum flying area, and the killing criteria of zone blockage warhead to airplane after the minimum flying area on runway was repaired. The model of drop points of anti-runway warhead and zone blockage warhead was established, and the calculation method of minimum flying area to judge the blockage probability of anti-runway warhead to runway was proposed as well as the calculation method of killing probability of zone blockage warhead to flying airplane. The evaluation model of runway blockage efficiency under combined blockage by the two kinds of blockage warhead was obtained. Under the conditions of different assembly scale of anti-runway and zone blockage warhead carried by one dispenser, the probability of blockading runway with 600 m long and 45 m wide was calculated. The result shows that the evaluation model can offer an important reference value for the design of blockage method of submunition and the efficiency evaluation of other blockage effect.
