摘要：

Time variations of current values of the velocity and propagation distance of the front of a gas-powder jet are studied as functions of the ratio of masses of the powder charge and the ejected fire-extinguishing composition. Three mechanisms of propagation of a pulsed gas-powder jet are established. An optimum range of mass ratios is obtained that provides for maximum values of the propagation distance of the gas-powder jet for barrels of various calibers and lengths.
