Estudio paramétrico y simulación dinámica de fluidos computacionales (cfd) de los efectos de integración aerodinámicos entre el sistema de propulsión y fuselaje para un vehículo aéreo no tripulado (uav) utilizado en agricultura

Abstract

The present work analyzes the integrated aerodynamics effects between the fuselage and the propulsion system of a fixed wing UAV, The atmospheric and operating conditions for an UAV have been established in order to operate in the Quito city, consequently the unmanned aerial vehicle Skywalker x8 has been selected because it has favorable characteristics in comparison with other UAVs used in the agricultural field. By the XFLR-5 and the ANSYS Fluent software, the aerodynamic characteristics and the behavior of the air flow between the fuselage and the propeller inlet have been obtained. In order to validate these results, public domain information has been used obtaining great similarity with other previous works. With the results of the analysis of the air flow carried in ANSYS Fluent, the disk theory has been used in order to determine the propulsive efficiency without boundary layer ingestion and when the boundary layer of the fuselage enters to the propulsion system.
