The experimental research on shape of detonation wave was done for cylindrical explosive charges with 5 different energetic materials with nitrocellulose and nitroglycerine. Energetic materials were manufactured with the technology for production of ball propellants. Shape of detonation wave was determined using the method of measurement of detonation wave arrival time to a certain point in the charge. Measurement system was developed in the Military Technical Institute (VTI) in Belgrade and had 16 fibre optic cables, multi-channel optical signal detector and oscilloscope. Curvature of detonation wave was determined at two different distances from initiation point. Average radii of detonation waves were determined using the regression analysis of experimental data. Also, the change in detonation wave curvature was observed at different distances from the detonator.
 

Key words: detonation wave, energetic materials, nitrocellulose, nitroglycerine.
