- Abstract
In order to investigate the effects of several nano combustion modifiers (nm-DPT, nm-CB and nm-Al) on the combustion properties of DB/Al-CMDB/RDX-CMDB propellants, the propellant samples were prepared through a solventless extrusion technique. The burning rates of propellants were measured by the strand burner method. The results showed that the nm-DPT enabled a plateau burning effect to appear for the Al-CMDB propellant in the pressure range of 8~22MPa, and the burning rate at 10MPa to exceed 29mm/s. The additional nm-CB powder increased the burning rates of the propellant, and the propellant burning rate at 10MPa exceeded 35mm/s. The nm-DPT enabled a plateau burning effect to appear for the RDX-CMDB propellant in the pressure range of 8~22MPa and a mesa effect in the pressure range of 12~22MPa, and the burning rate at 10MPa to exceeded 28mm/s. The additional nm-CB increased the burning rate of the propellant, the burning rate at 10MPa exceeded 30mm/s and the pressure exponent in the pressure of 16~22MPa was -0.10.
