Abstract

The paper investigated the effect of metal nanopowders additive on the combustion properties of HMX/CL-20/AP/polyvinyltetrazole binder/Al propellants. Using thermal analysis, the authors described the effect of aluminum, boron, zinc, nickel, copper, and molybdenum and identified the combustion in a pressure range from 4 to 10 MPa with a pressure step of 1 MPa. No significant correlation between the oxidation properties of the n-Me powders and the combustion properties of propellants was discovered. An addition of nanopowders caused an increase in the propellant burning rate by approximately 30 % for n-Al, n-B, n-Ni, and n-Mo independent from the pressure values. An addition of n-Cu resulted in a burning rate increase by a factor of 4.9 due to coppers’ probable catalytic activity during interaction with nitroesters and cyclic nitramines in a solid phase. n-Zn additive increased the propellant burning rate by factors 2.3 and 3.6 at 4 and 10 MPa, respectively, due to catalytic activity of zinc in a gaseous phase.
