Graduated in Industrial Chemistry from the University of Southern Santa Catarina (1984); specialization in Quality Engineering (1994) and master's degree in Materials Engineering (1999) from the School of Chemical Engineering of Lorena - USP; PhD in Catalysis and Physical Chemistry from the Université de Strasbourg, France (2003). Ricardo Vieira worked for thirty-five years at the Combustion and Propulsion Laboratory of the National Institute for Space Research (INPE) in Cachoeira Paulista, SP. Has experience in Chemistry, with emphasis on Heterogeneous Catalysis and Propulsion, working mainly on the following subjects: synthesis and use of carbon nanofibers as catalytic support and reinforcement of advanced polymeric materials, green propellants, satellite thrusters, catalytic decomposition of hydrogen peroxide and nitrous oxide. Currently retired from INPE, partner of the company ACM Vieira Aprimoramentos, providing consultancy to Peroxidos do Brasil in Curitiba, PR, in the development of catalysts and recovery of noble metals.

This work aims to develop a monolithic catalytic support for hydrogen peroxide decomposition for aerospace applications. The geometry of the monolithic catalyst will be studied and implemented in order to reach the induction time similar to those found in traditional catalyst pellets, however with a lower pressure drop. The new geometry will be built by additive manufacture using Selectiv…
The aim of this work is to develop an analytical and experimental database of a hypergolic couple with low toxicity and high thrust density consisting of rocket grade hydrogen peroxide as oxidant, and promoted ethanol with catalysts as fuel. Firstly, the physical and chemical processes leading to the hypergolic ignition of liquid propellants will be studied. Secondly, it will be verified …
Nitrous oxide (N2O) is suggested to be a potential monopropellant for micro-thruster applied in satellites as a result of its non-toxicity, self-pressurization, and self-sustaining reaction. This monopropellant has drawn great interests due to its low cost and little hazard in handling. A key-technology for N2O monopropellant decomposition is the development of a catalyst that could be us…

This work aims to develop catalytic materials of manganese-doped cobalt spinels, to be used as catalysts in the decomposition of hydrogen peroxide (H2O2), allowing multiple cold starts on a satellite monopropellant microthruster. Initially, it will be mounted, in partnership with Peróxidos do Brasil company, a pilot plant for concentration of H2O2 from 70% to 90% by mass. In parallel, sp…
