Projeto de um propulsor a propelente sólido com impulso total máximo de 1300 N • s

Abstract

This work presents the development of a model for the design of a solid propellant thrus ter, aimed at devices with a maximum total impulse of 1300 N · s. The model integrates fundamental sizing theories and design recommendations, with an emphasis on safety and manufacturability. Implemented in Python, following object-oriented programming (OOP) principles, the model ensures modularity, code reuse, and ease of expansion. It includes critical analyses such as heat transfer, combustion chamber pressure, and structural sizing, reducing the need for external software. Although the code has not been made available, it generates all the necessary geometry from a few inputs, facilitating the application of opti mization algorithms. The results indicate good accuracy compared to experimental results and literature data. However, complete validation requires the fabrication of the motor. The work resulted in an effective model, prepared for future expansions and integrations with optimization algorithms. It is recommended to fabricate the designed motor for empirical validation and to explore more efficient geometries through future optimizations.
