Experimental Study on a Triple-base Propellant Formulation

摘要

In order to optimize the triple-base propellant's preparation technology and improve the combustion performance, used the half solvent method to prepare a series of propellant samples with different solvent ratios, and used the close bomb experiment and scanning electron microscope (SEM) and other experiments to study the microstructure, shrinkage rate and combustion performance. Results show that with the same formula but different solvent ratios, the shrinkage rate and the internal structure of the triple-base propellant were quite different, the solvent ratio 0.34～0.35 propellant's combustion performance is quite good and its formula was the best recipe.
