Diseño de la estructura de un cohete de tres etapas para transportar una carga útil de 200 kg a una órbita baja de la Tierra

Abstract

This article presents the conceptual design of the structure of a three-stage rocket capable of carrying 200 kg to low Earth orbits, developed in the project of grade of two students of aeronautical engineering from the Fundación Universitaria Los Libertadores. The design starts from the decision of how they are going to form the structure to protect three rocket engines inside, considering the force generated by the first one since this is the largest, followed by the design of the profiles that make up the structure and selection of a lightweight material such as aluminum (Al) to support efforts up to 280 N/mm2, hence the calculation of total area, the required areas and moments of inertia, begins with the calculation of the stringer profile, followed by the bulkhead profile and even the rivet diameter obtaining dimensioning, structural distribution and the final configuration of the structure.
