چکیده

Composite solid propellants were prepared with and without nano-alloys (Ti-Co, Ti-Ni, Ti-Zn), where nano-alloys used as catalyst. These nano-alloys are prepared by hydrazine reduction method. Catalytic properties of these nanomaterials were measured on Ammonium perchorate/hydroxyterminatedpolybutadiene propellant by thermogravimetery analysis and differential thermal analysis. Both experimental results show enhance in the thermal decomposition of propellants in presence of nano-alloys. In this differential thermal analysis method experiments had done in 3 heating rate â1=5, â2=10, â3=15 degree on minute. Independent to model free; calculation of activation energy of high temperature decomposition step was done by using following kissinger equation. Burning rate of propellants is also calculated.
