Abstract:

Experimental investigations were made of the effect of injecting H2O2 solutions into the chamber of a catapult during burning of the propellant in a large-volume closed bomb. Solutions of H2O2, in concentrations varying from 0 to 60, were tested, and oscillograms of pressure and thermocouple temperatures vs time were obtained. H2O2 solutions, injected during burning of conventional propellants, exhibited to a significant degree properties of a propellant and of a coolant. A 10 concentration was ample for the complete elimination of C formation in the chamber. Synthetic materials used for experimental injector piston seals neoprene and Teflon must be protected from the combined action of hot gases and free O in order to attain satisfactory life.
