doi:10.3969/j.issn.1000-1093.2015.06.023

Abstract

Abstract: A novel five unit (NC-NG-DNTF-HMX-Al) high energy composite propellant suitable for screw extrusion process is developed. The main properties and key technology of the propellant are discussed in detail. The results show that the energy property of the propellant is improved by using 3,4-dinitrofurzananofuroxan(DNTF), spherical Al powder and HMX. Chemical stability and output energy of the propellant are further enhanced by adding energetic stabilizer P-Nitro-N-Methylamine (PNMA). Application of an energetic catalyst which guarantees good burning rate contributes additional energy to the propellant. The new propellant formulation has excellent comprehensive property.

Key words: ordnance science and technology, modified double base propellant, DNTF, HMX, Al powder, PNMA, energetic catalyst
