“…O material utilizado na câmara de combustão do MFPL L75 é o cobre cromo C18200, por apresentar alta condutividade térmica e elevada resistência mecânica em tração quando tratado termicamente [2]. Visando aumentar a taxa de extração de calor da câmara de combustão, esta é envolta por uma jaqueta de refrigeração, fabricada de aço inoxidável AISI 316L [3][4][5]. O AISI 316 L possui um ótimo desempenho, tanto em altas temperaturas, quanto em baixíssimas temperaturas, bem como excelente resistência a corrosão, ductilidade e soldabilidade [6].…”

“…Throughout the years, the experience obtained by the Institute of Space and Aeronautics, has shown that purchasing rocket engines and their components from foreign countries is an extremely delicate task, since the technology of rockets is subject to the restriction of the countries that signed the Missile Technology Control Regime (MTCR), in addition to experiencing embargoes of political, commercial and strategic origins (TORRES et al, 2009).…”

This work presents the study conducted at the Institute of Space and Aeronautics, an organization of the Department of Science and Aerospace Technology (DCTA-IAE, in the Portuguese acronym), to investigate the erosion of the thermal protection, nozzle throat insert, and thermal protection of the convergent manufactured in EPDM rubber of the convergent section of the nozzle, during the sub scale solid propellant rocket motor static firing test. During this study, tests were conducted in order to evaluate the performance of the nozzle ablation of insert material and also of the rubber to protect thermally the metallic motor case and also to the convergent, in addition to verifying the functionality of the adhesion between the propellant and the rubber. For the work herein presented, specifically, only the results inherent to the evaluation of the nozzle insert material and the deterioration of the EDPM rubber in the interface with the conducted in order to evaluate the performance of nozzle ablation of insert material, and also of the rubber to protect thermally the metallic motor case and also to the convergent, in addition to verifying the functionality of the adhesion between the propellant and the rubber. For the work herein presented, specifically, only the results inherent to the evaluation of the nozzle insert material and the degradation of the EDPM rubber in the interface with the graphite material insert for a test time of 56 s will be analyzed. After the tests, non-conformities were detected in components of the engine that subsequently led to a careful analysis of the reasons, as well as to the implementation of solutions for the redesign of components with the aim of improving the safety and assuring the structural integrity of the rocket engine for further tests.

“…Ao longo dos anos, a experiência obtida pelo Instituto de Aeronáutica e Espaço, que é uma organização do Departamento de Ciência e Tecnologia Aeroespacial (DCTA/IAE), tem demonstrado que adquirir motoresfoguetes e seus componentes no exterior é uma tarefa extremamente delicada, pois a tecnologia de foguetes está sujeita às restrições dos países signatários do Missile Technology Control Regime (MTCR Regime de Controle de Tecnologia de Mísseis), além de sofrer embargos de natureza política, comercial e estratégica (TORRES et al, 2009).…”
