Ti-alloys: Potential nano-modifier for Rocket Propellants

Abstract

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���� 5���� =10,���� 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.
