The experimental results of studying in-water initiation of propane-oxygen charges in the form of ring bubbles by using 2, 4 and 6 electrical sparks have been presented. In discharge gaps, sparks were initiated from the single capacitor storage of energy 2 J and were located along the ring perimeter of diameter 52 mm at the same distance from each other. The difference between the processes of energy release in the combustion of gas charges has been revealed in the analysis of force pulses measured by the piezo-dynamometer with time resolution of 2.6 μs. It has been shown that for the same gas charges in the initiation of gas by multispark discharges, thrust characteristics have both qualitative and quantitative advantages. As the number of sparks increases from 2 to 6, the amplitude of force pulses rises to 30% and a specific pulse increases to 20% for the same gas charges.
