Title: Effect of RDX on mechanical and combustion property of variable burning rate gun propellant
Abstract: In order to achieve the purpose of the inner burning rapidly,high-energy ammonium nitrate explosive——RDX is added to the inner of variable-burning rate gun propellant.Meanwhile the mechanical properties of whole gun propellant have been affected with the introduction of RDX.Through the contrast of different tensile strength,shear strength and combustion phenomenon of the closed vessel test,the following results could be obtained.With the increase of RDX's content,the tensile strength and shear strength of variable-burning rate gun propellant decrease,meanwhile the properties of progressive combustion become good;with the growth of RDX's particle size,the propellant's tensile strength decreases,and the properties of progressive combustion become weak.
