Introduction Solid propellant, as a major Energetic Materials in China, is widely loaded in rockets, missiles.
As a high energy density materials, solid propellant are flammable, explosive, which maybe initiated unexpectedly under specific excitation conditions through high-speed screwing.
The extrusion fluid temperature gets another climax where material gathers most.
