Abstract
Propellers are providing throughout history a notorious contribution to the development and construction of various engineering systems, such as airplanes, helicopters, drones, ships, submarines and even land vehicles. Specifically for aircrafts, this device is responsible for providing thrust, converting the power generated from an engine. This work aims to study the performance of propellers through computational fluid dynamics (CFD), considering the influence of crosswinds. After validating the CFD model, two different small propellers were used in the simulations, comparing the results without crosswinds from the reference experimental results. Three simulation conditions were used, varying the intensity of the crosswind and the propeller advance ratio. After the simulations, the perception is that crosswinds decreases propeller efficiency for higher advance ratio values, whereas it had no negative effect on static condition.
