Diseño y construcción de una propela APC 12x6 EP para drone skywaker con materiales compuestos de matriz polimérica reforzados con fibra natural: componente práctico.

Abstract

The use of unmanned aerial vehicles (UAVs) has been increasing in recent years. These are used for field work, messaging, engineering, combat, and scientific research. Therefore, the demand for equipment and spare parts, especially in the propulsion system (Engine - propeller) is increasing. In Ecuador there are no manufacturers of this equipment, so their costs are quite high. Drone propellers are usually made from plastic materials. which means that, once they stop working, they are discarded and end up being a problem for the environment. The present work focused on the manufacture of an APC 12x6 EP propeller for a Skywaker drone made of a polymer matrix composite material reinforced with natural fibers, to obtain an alternative to plastic propellers. the project was developed from the studies carried out by Rivera J., 2022. In the first place, the selection and manufacture of the composite material that presented the best mechanical properties based on the parameters of a standard propeller was carried out. Once the composite material was manufactured, the propeller was designed and manufactured using the CNC machining method. Since this process allows obtaining elements with more complex geometries. Finally, the propeller was subjected to wind tunnel tests under controlled flow with the help of a propulsion system to compare the experimental data with the theoretical ones.
