NEPE Propellant

Enhanced combustion under depressurization

A composite solid propellant with a three-dimensional non-planar microstructure of AP/HMX particles in a nitrate ester binder, where leading-edge flames intensify burning and enhance gas-phase heat release, providing microscopic insights into combustion instability in solid rocket motors.
