Original abstract

The article is focused on the assessment of the most probable way of an attack to the civil aircraft, the assessment of the effect of this attack and capability of the aircraft to continue in the flight after the damage. The attack with missile with the fragmentation warhead was assessed as the most dangerous one. The influence of this attack can be simulated using finite element method, for the validation of the functionality of this model was performed suitable shooting experiment. The specimen was made as a semi-monocoque skin panel and was impacted by the fragments of known mass, velocity and direction of the stroke to the impacted area. The experiment proved that single fragment causes only small damage and has a little influence to the capability of the panel to carry loads. Also more fragments, with proper distance between each other, damage more single parts but they do not cause bigger damage to the panel which can be explained as a sum of partial influences of single fragments. The results of this experiment were used for the improvement of the numerical calculation of the damage.
