摘要：

For glycidyl azide polymer (GAP) propellant and polyethylene terephthalate (PET) propellant with different cyclot-rimethylenetrinitramine (RDX) particle size, a split Hopkinson pressure bar (SHPB) apparatus was used to carry out high-strain rate (1 000-6000s-1) dynamic impact experiments, combining the optical measurement technology of high-speed photography with digital holography, three high-speed cameras were simultaneous used to synchronously observe the generation of damage, ignition response and energy growth process of various propellants under impact conditions. It was found that the ultimate strength of GAP-based propellant under high-strain rate compression is twice that of PET-based propellant,and the elastic modulus is more than doubled at different strain rates. Compared with coarse-grained RDX propellant, the ultimate strength of medium-grained RDX propellant is increased by 80%,and the elastic modulus is increased by 148% . In addition, compared with PET-based propellant and medium RDX particle size propellant, GAP-based propellant and coarse RDX particle size propellant are easier to ignite and burn under high-strain rate compression conditions. However, the reaction of medium RDX particle size propellant is more intense and complete. © 2023 China Ordnance Industry Corporation. All rights reserved.
