The efficiency of conversion of energy in an electric-discharge light-gas accelerator of bodies

The results are given of investigation of the processes of energy transfer in a power supply-projectile system, which occur under conditions of acceleration of bodies by an electric-discharge light-gas accelerator with a caliber of $31.5$ mm, and of the effect of the initial parameters of the working gas and a number of other factors on the efficiency of energy conversion. It is found that the efficiency of electric-discharge lightgas accelerator with the velocity of launching bodies ranging from $1800$ to $6000$ m/s is 6 to $19$ $\%$; in a number of experiments, the efficiency reaches $23$ $\%$.
