THE MEASUREMENT METHODS OF NONSTEADY BURNING RATE OF HIGH-ENERGY MATERIALS
Two independent measurement methods of nonsteady burning rate of solid propellants − a method of high-speed filming and a method based on statement and decision of inverse problem of internal ballistics are considered. Results of measurements nonsteady burning rate of propellants are presented at sharp pressure release in semiclosed volume. The lead comparative analysis has shown that the considered methods are complementary. The applicability borders estimation of inverse methods of identification of nonsteady burning rate has shown perspectivity of use of these methods not only in laboratory conditions but also at measurements in large-sized solid-propellant gas generator.
