Factors affecting the velocity of launching bodies by means of an electric-discharge light-gas accelerator
Annotation
The effect is investigated of a number of factors, which accompany the operation of an electric-discharge light-gas accelerator, on the velocity of launching bodies. One such factor is the contamination of the working gas with electrode erosion products. It is found that, at a temperature of the working gas of 25003000 K and below, the erosion of electrodes and walls of the discharge chamber does not cause a contamination that would result in appreciable decrease in the efficiency of the process of acceleration of bodies using an electric-discharge light-gas accelerator. It is determined that, with the launching velocities equal to or lower than the velocity of sound in the working gas, the actual values of launching velocity are 1015% lower than the calculated (maximal) values.
