Due to technological improvements, miniaturisation of UAVs is possible in different type of aerial vehicles, varying from airplanes to helicopters. Different from airplanes, helicopters have continuous airfoil motion, which introduces aerodynamic complications, such as a periodically varying incidence angle. Moreover, their small dimensions and low velocities imply low Reynolds numbers O(104 105) operating environment, which affects the airfoil performances by for example a laminar separation bubble (LSB). In order to improve the design of UAVs with pitching airfoils, it is of interest to gain knowledge in the flow field of moving wing bodies.
