Development and Optimization of a Catalytic Thruster for Hydrogen Peroxide Decomposition

Journal of Aerospace Technology and Management, 2014
Hydrogen peroxide is a non toxic, low cost, green monopropellant with a significant potential for applications in satellite microthrusters. It presents a density-specific impulse, similar to hydrazine. A new bulk mixed oxide catalyst for decomposition of
