Low Re, High Α Wing Aerodynamics for Micro Air Vehicle Applications
Low Re, high alpha wing aerodynamics for micro air vehicle applications
Driven by the need to develop suitable aerodynamic designs for micro air vehicles, results from a CFD investigation of low Reynolds number, high angle-of-attack wings are discussed. Results are presented for the effects of planform shape, camber, and angle-of-attack at Reynolds number of 500. A drag polar is presented and shows a lift peak at 20 degrees. A tip vortex moves streamlines away from the tip and toward the root, thus leaving a dead fluid region. A spiral vortex and recirculating flow are also observed at high angles of attack.
