In order to study the fragility of NEPE propellant,a simulation device was adopted to test NEPE propellant samples which impacted target at different velocities. The damaged samples were tested in closed bomb and the burning performances of the damaged samples were analyzed. Results show that the maximum pressure rising rate and burning rate of NEPE propellant samples increase with increasing of damaged situation. The NEPE propellant samples firstly burn,and then detonate,when the impact velocity is more than 192 m·s-1.
