Given the importance of fuel reduction in the aeronautical industry, for both economic and environmental purposes, the last few years have seen the popularization of wingtip devices as a mean to increase aerodynamic efficiency. This work presents and studies several wingtip device geometries at different flight conditions, assessing the impact that a number of geometric parameters cause on the lift and drag forces. This is performed through computational uid dynamic simulations, potential flow-based panel method analyses, and an attempt at experimental measurements. The main conclusions derived from this study indicate that, for several wingtip device configurations, it is possible to achieve a 10% increase in the aerodynamic efficiency of a given wing. The validity of the panel method employed is discussed, and several considerations are presented towards future numerical and experimental research.
