This study was inspired by take-off and landing performance improvement of small unmanned aerial vehicles (sUAV). It focused on little researched low Reynolds nomber range and on simple actuation mechanism. Existing semi-empirical method was used to design a single- and double-slotted flap for a DAE 31 airfoil. Results from low-speed windtunnel test and URANS simulations are presented.
