Sustainable design of a nanosatellite structure type CubeSat as a modular platform for tests

This article is intended to contribute to the development of proprietary technologies and the evaluation and selection of integrated technologies in the study of the aerospace concept necessary for the processes of technological appropriation. The problem addressed lies in the lack of modular platforms and lowcost test systems for experimental development and simulations of satellite systems. Therefore, compare to this the proposal of a scalable modular platform of the 1U CubeSat standard is presented as the main results. The design and characterization process presented from the concept of sustainability, contributes to the use and development of low-cost equipment that minimizes the impact on the environment and, in turn, is practical for its implementation in activities of groups and research centers that promote the diffusion of space technologies in Colombia. The methodology of sustainable design, the definition of design principles and conceptual design, which is materialized with the application of quality function deployment method (QFD), the theory of inventive problem solving (TRIZ), the manufacturability-oriented design (DfM), assemblability (DfA), environmental impact (DfE), reliability (DfR), and safety assessment, are relevant for compliance with the CubeSat operating standards described in CDS. Finally, several constructive modes of the low cost test platforms are proposed with different materials such as 3D prototyping in paper, ABS, MDF wood and aluminum. All of them are small-scale satellite structures designed and constructed at low-cost. These designs result in the materialization to test on-board systems and integration resistance in assembly and materials, in laboratories as vibration test-bench, for research groups or companies interested in promoting the development of space technologies. Este artigo busca contribuir para o desenvolvimento de tecnologias próprias e a avaliação e seleção de tecnologias integradas necessárias para os processos de apropriação tecnológica no campo aeroespacial. O problema abordado surge da falta de plataformas modulares e sistemas de teste de baixo custo permitindo o desenvolvimento experiencial de sistemas de satélites e a realização de simulações. Portanto, a proposta de uma plataforma modular e escalável do padrão 1U CubeSat é apresentada como resultado final. O processo de desenho desta plataforma, sob critérios sustentáveis, contribui para o desenvolvimento de equipamentos de baixo custo que minimi
