Pyrocutter cartridge is an autonomous device that uses pyrotechnical charge for cutting rope while saving catapulted pilots. This work presents construction design and results of inner ballistic tests of pyrotechnical charge and pyrocutter cartridge as a functional device. The chosen pyrotechnical charge secures the necessary delay time. The scope of this thesis includes statistical analysis of the delay time, block diagram of used measuring instruments and block diagram of system functions as well as an estimate of reliability.
Key words: pyrotechnic, pyrocutter, pyrotechnical charge, internal ballistic testing, catapult seat.
