A New Method for Measuring the Pressure Increase in Energetic Compositions in a Maximally Filled Container

Abstract

A new method for direct measurement of the pressure increase in energetic compositions (propellants, powders, and explosives) upon thermal decay of energetic samples is described. This method is applicable to the control of the decay kinetics of elastic compositions during long-time storage. The testing of this method showed that the error in measuring the pressure increase in the systems under study during long-time storage at a constant temperature and the maximum filling of the reaction container did not exceed 4%.
