Resumen
[ES] El objetivo de este trabajo es crear un marco numérico para estudiar, por medio de simulaciones URANS, la dinámica de un vehículo aéreo no tripulado sometido a ráfagas de viento y aplicar leyes de control para estabilizar su respuesta. La aeronave se representa por medio de un perfil aerodinámico 2D asociado a un modelo estructural que lo hace naturalmente estable. El software utilizado es StarCCM+ y su módulo de interacción fluido-estructura, DFBI. Se simulan tanto ráfagas frontales como transversales y se implementara un controlador proporcional de cabeceo. Se compara la respuesta del perfil con estudios experimentales existentes.

The aircraft is represented by means of a 2D airfoil associated with a structural model that makes it naturally stable. The software used is StarCCM+ and its fluid-structure interaction module, DFBI. Both frontal and transverse gusts are simulated and a proportional pitch controller is implemented. The profile response is compared with existing experimental studies.
