Análise da distribuição de calor na área de um lançador de foguetes de médio porte do centro de lançamento de Alcântara

Abstract

Space activities add great value to society in technological, economic, and social terms. Thus, the pursuit of development and advances in this area is of great importance, since this segment has very promising hopes and realities. Analyzing and verifying scenarios for performing these activities is essential as they require a high degree of reliability and security. It is in this line that this work is inserted, analyzing rocket launch scenarios located at the Alcântara Launch Center (CLA) which is one of the strategic regions for the development of the Brazilian Space Program. In this work we study the thermal behavior of the nozzle exhaust gases in a midsize rocket at launch, evaluating via finite element analysis for these conditions. In addition, there is verification of the spread of heat through the environment by assessing the safety distances that a person may be exposed to during launch. Using SolidWorks software for launch modeling and simulation, the temperature plot was plotted along with points scattered on a trigonometric plane at three different heights, finding values above 100 ° C still within the limit of an area of 3600 square meters. cause risks of side effects of burns and increased skin impermeability.
