Abstract

AbstractExperimental results about rb(P) laws of double‐base propellants are presented. The influence of many parameters (calorific potential, fabrication process, additives) is studied. With surface structure examination, we show that the first super‐rate (P < 100 bar) is in relation with the presence of a carbon layer which increases chemical reactions. The second super‐rate (200 bar < P < 400 bar), more physical than chemical, is in relation with the presence of globules (probably PbO) which increase the thermal conductivity near the propellant surface.
