Dissertação (mestrado)—Universidade de Brasília, Faculdade de Tecnologia, Departamento de Engenharia Mecânica, 2013.The First chapter of this work provides a preliminary overview of the proposed activities outlining the motivations, objectives and proposed methodology to achieve the settled goals. The second chapter of this work analyses the markets for a microsatellite launcher and estimates the possible market share attainable by a Brazilian launcher in the category proposed. The third chapter presents the optimization technique employed and the various technological alternatives considered comparing then both qualitative and quantitative. The MDO algorithm is presented and detailed in this chapter. The forth chapter of this work proposes 7 optimization cases contemplating the most engineering and economically wise design alternatives. In the same chapter the 7 optimized designs are compared and a resulting solution is obtained. The resulting solution is then optimized again addressing design problem encountered during the optimization of the earlier 7 cases. The fifth chapter proposes a conclusion for the work and outlines future initiatives for continued work on the design of the microsatellite launcher.
