Possibility of using gas-generating compositions for increasing the rocket propulsion efficiency

A possibility of ballistic efficiency of space rockets with main rocket propulsion engines by means of developing a system of gasification of unburned residues in propellant tanks with the use of gas-generating compositions with self-sustained combustion is considered. The criterion for choosing gas-generating compositions is the increment of the characteristic velocity of the rocket stage acquired due to combustion of gasified propellant residues. The results of the present study show that the proposed method of gasification of liquid propellant residues increases the energy characteristics of the rocket.
