Diseño y construcción de un prototipo de multirrotor de bajo peso y portátil, para inspección y monitoreo del volcán Cotopaxi

Abstract

The aim of this work is to design and build a prototype of low-weight and portable multirrotor for the inspection and monitoring of the Cotopaxi volcano. In this context, the work was carried out through the concurrent design methodology. First, the performance of the quality function was carried out in order to define the technical specifications of the aircraft according to the needs and desires of the users. Then, based on these specifications, a functional analysis was developed that allowed the identification of a solution principle composed of three modules: structural, propulsion and control. Then in the materialization design stage the propulsion system was defined by the theory of moment and the blade element theory according to the height of the Cotopaxi volcano. As for the structural module, the appropriate material for the construction was selected and the dimensions for the entire multirrotor frame were established in function of the total thrust generated by the propeller-motor assembly. On the other hand, the appropriate flight controller was selected for the aircraft and a configuration of the basic parameters was made to ensure the stability of the equipment in the air according to previous studies carried out. Finally, the prototype of Multirrotor was built using additive manufacturing resulting in a coaxial hexacóptero with a total weight of approximately 3.5 [Kg] which can fold to ensure portability.
