“…The consequence of a bird sucked into the engine can be engine shutting down [6,8], whereas penetrating the canopy can cause a serious injury to the pilot, making him unable to continue piloting an aircraft. It should be remembered that apart from the compulsory experimental strength tests, conducted in laboratory conditions in order to meet certification requirements, there exist various theoretical methods which are realized on the basis of proper mathematical modelling of the bird strikes [5,10]. Therefore, due to lack of certification requirements for the category of normal, utility, acrobatic aeroplanes and small helicopters and a high degree of damage, especially to the cockpit canopy, it seems justified to conduct simulation of the strike impact by means of proper software.…”
