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 β1=5,β2=10,β3=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
