Abstract

MAIA, Fernanda Francisca et al. Development and Optimization of a Catalytic Thruster for Hydrogen Peroxide Decomposition. J. Aerosp. Technol. Manag. [online]. 2014, vol.6, n.1, pp.61-67. ISSN 1984-9648.  https://doi.org/10.5028/jatm.v6i1.286.

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 hydrogen peroxide has been developed and tested in a 2 N thruster with modular parts, allowing the use of catalytic beds with different diameters and lengths. A method of experiment design with a star configuration was implemented to optimize the catalytic bed geometry, in order to yield complete peroxide decomposition, reduce thruster size and volume and provide maximum thrust.

Keywords : Satellite propulsion; Hydrogen peroxide; Mixed oxide catalyst; Catalytic bed optimization.
