Influence of AP Particle Size on Burning Characteristics of HMX/AP Propellants Supplemented with Fe2O3

open access: yesPropellants, Explosives, Pyrotechnics, Volume 50, Issue 6, June 2025.
ABSTRACT Nitramine propellants have attracted considerable attention in the domain of solid rockets and gun propulsion because of their energetic and smokeless features. Ammonium perchlorate (AP) is the widely used oxidizer in propellants owing to the excellent burning characteristics.
