Simulación y fabricacion de una propela apc 12x6 ep para drone skywaker con materiales compuestos de matriz polimérica reforzados con fibra natural: componente teórico.

Abstract

The present work uses the numerical prediction methodology at small scales to determine the efficiency of an APC 12x6 EP propeller. For the study, the use of a commercial software called ANSYS FLUENT is implemented, which allows the study of physical problems in the area of fluid dynamics. The software allows the simulation of fluids, with the aim of understanding the physical model of the APC 12x6 EP propeller, obtaining fast and precise results, thus establishing working conditions to which the propeller will be subjected. Once the working parameters have been established, the thrust force generated by the propeller is obtained, as well as its moment. The results obtained in the different simulations are compared with the data available on the APC commercial to stablish the relative error between them. Tetrahedral unstructured meshing was used as it can be easily coupled to problems involving solids with complex geometries. To consider the effect of rotation of the propeller, MRF (Moving Reference Frame) is used, thus varying the working conditions. In this way, with the loads obtained in the simulation, a structural analysis is carried out to establish the best option for the composite material of polymeric matrix reinforced with natural fiber.
