THE EFFECTS OF ADDITIVES ON PROPELLANT PERFORMANCE AND MOTOR OPERATING CONDITIONS

Abstract

The theoretical performance of inhibited red fuming nitric acid and unsymmetrical dimethylhydrazine with various additives was computed. Performance data were computed assuming a chamber pressure of 1,000 psia with optimum expansion to 14.7 psia. In addition, the effect of additives or of programmed density on motor operating conditions is discussed. With a constant nozzle throat area and a constant propellant flow rate, an additive (introduced to the combustion chamber) increases the chamber pressure significantly. A method for calculating this pressure increase is given. (Author)
