Projeto conceitual de uma sonda estratosférica reutilizável utilizando MBSE para estudo de modelos climáticos e de eventos ondulatórios na atmosfera

Abstract

This work presents the conceptual design of a stratospheric probe using Model-Based Systems Engineering (MBSE). The main objective of the study is to compare and validate temperature and wind models, as well as to use system measurements along with other observations to understand the origin of wave phenomena in the atmosphere. The methodology used was the NASA systems engineering approach, which allowed the development of the project in a systematic and efficient way. In addition, MBSE was used, an approach that uses models as tools to integrate and manage information throughout the project life cycle. The open-source tool Capella was used to model the system, allowing the derivation of a solution concept from the captured stakeholders’ problem, and also enabling the visualization of interfaces and traceability of all elements. The results were obtained through multiple systems engineering iterations, culminating in defining the final system configuration containing all subsystem components, cost and risk analysis. It was concluded that the proposed concept of the system solves the stakeholder problem previously identified, and that the use of MBSE and the systems engineering approach were crucial to the success of the project.
