Aerodynamic Performances of Paper Planes

Journal of Advanced Research in Fluid Mechanics and Thermal Sciences, 2020
Paper plane has a high potential to be upgraded as a Micro Air Vehicle (MAV). Due to its simplicity, paper plane offers easier design option compared to the biological inspired designs as shown in recent MAV development. However, researchers have underestimate and overlook the basic aerodynamic performance induced by these paper planes.
