Empirical research of human-weapon system

Rapid firing of the Skorpion vz.61 machine gun was registered at a police shooting range. The shooting was executed by a policeman from the secret service. The registration was done with the use of a fast digital camera Phantom v9.1 together with the necessary equipment. With the use of the specialised TEMA software, which serves to analyse the recorded image, the courses of the variation of kinematic quantities characterizing the weapon movement were obtained. On the basis of the courses of the variation of the displacement, velocity and acceleration over time, the behaviour of the machine gun in thirteen characteristic points of its operation was specified.
